QLEDadalah alternatif kepada OLED yang dibangunkan oleh Samsung. Ia merupakan akronim kepada quantum dot light-emitting diode, iaitu teknologi bagi menyelesaikan masalah burn-in yang sering berlaku pada OLED. Panel yang digunakan masih lagi berasaskan panel LED, tetapi setiap komponen LED itu direka dengan konsep titik kuantum.. Namun, Samsung ada yang lebih baru iaitu Neo QLED - apa pula
Durante a CES 2017, que aconteceu em janeiro, Samsung e LG apresentaram suas novidades no segmento de TVs. A primeira mostrou sua nova tecnologia de telas, a QLED. Já a segunda mostrou um aprimoramento da já existente tecnologia OLED. Ambas as tecnologias prometem travar uma batalha épica no mercado, disputando cada um dos clientes. Neste artigo iremos explicar as diferenças entre as duas tecnologias e as suas respectivas vantagens. QLED TVs QLED da Samsung exibem cores com mais qualidade e volume Foto Divulgação/Samsung — Foto TechTudo QLED é a sigla para Quantum Dot Light Emitting Diodes. Ela foi desenvolvida pela Samsung que apresentou a novidade na CES 2017, uma das maiores feiras de eletrônicos do mundo. A tecnologia é baseada nos famosos pontos quânticos, que são minúsculos cristais que absorvem determinadas frequências de luz e emitem outras, conforme a necessidade. Os pontos quânticos, ou quantum dots QD, em inglês foram usados para melhorar a qualidade das telas LCD e LED e, assim, darem sobrevida à tecnologia. Porém, nas mãos da sul-coreana Samsung, os pontos quânticos deram origem as TVs QLED. A principal vantagem desse tipo de tela é que ela promete reproduzir 100% das variações de cores do padrão DCI-P3 em qualquer nível de luminosidade. Isso significa que você pode ajustar o brilho no máximo e, ainda assim, a TV QLED irá mostrar cores fiéis à realidade. Aplicativo do TechTudo receba as melhores dicas e últimas notícias no seu celular QLED usa o conceito dos pontos quânticos mais brilho por toda a área da tela, contraste maior e cores mais precisas. Na imagem, a comparação da TV QLED com uma convencional Foto Divulgação/Samsung — Foto TechTudo Além de serem capazes de reproduzir a totalidade das variações de cores, as TVs QLED possuem um brilho impressionante. Os modelos que estavam em demonstração alcançavam uma faixa de a nits índice de brilho nos picos de luminosidade. A média é de apenas nits. Isso faz com que as TVs QLED se saiam bem em qualquer tipo de iluminação ambiente. Outra vantagem dessa tecnologia é o seu ângulo de visão. Ela pode compensar os reflexos criados pela luz ambiente e, desta maneira, exibir uma imagem perfeita tanto se olhada de frente quanto de lado. Além disso, as telas QLED têm potencial de consumir metade da energia das OLED tradicionais e de terem um custo de produção menor. A tecnologia QLED pôde ser vista na CES deste ano por meio dos televisores Q7, Q8 e Q9, que possuem uma tela de 65 polegadas e resolução 4K. Infelizmente, ainda não há previsão de quando essas TVs chegarão às lojas brasileiras e nem o seu preço. Mas podemos ter certeza que serão bem caras. OLED A tecnologia OLED Organic Light Emitting Diodes é um pouco mais antiga e já é utilizada até por outras fabricantes. Mas quem está investindo pesado é a LG. A grande diferença entre um display OLED de um QLED é que o primeiro não precisa de um painel adicional de LED, chamado de backlight. lg_md_001LG Signature - OLED TV W é quase tão fina quando um iPhone 7 Foto Anna Kellen Bull/TechTudo — Foto TechTudo Isso é possível graças aos diodos orgânicos emissores de luz, que são responsáveis por emitir e controlar sua própria luz e, por isso, não precisam do auxílio do backlight. Com a exclusão desse item, que é obrigatório inclusive nas novíssimas TVs QLED, a LG pode fabricar televisores absurdamente finos. A série W, por exemplo, tem apenas 2,6 milímetros de espessura. O “W” vem de “wallpaper”, ou papel de parede. Daí você já tem ideia de quão fina ela é. O televisor é projetado já para ficar preso à parede e não possui sequer um pedestal ou apoio para mesa. Ele se fixa à parede por meios de hastes com ímãs. Sua instalação se assemelha a de um quadro. Os altos falantes também saíram. Agora o áudio das TVs OLED da LG são transmitidos por uma espécie de soundbar que fica separada do display. É nesse acessório que também ficam as diversas entradas, como HDMI e USB. A LG OLED TV W TV é pendurada na parede usando ímãs Foto Anna Kellen Bull/TechTudo — Foto TechTudo As TVs OLED, em geral, tem menos brilho e um ângulo de visão menor quando comparada com uma TV QLED. A linha W da LG não tem previsão de chegar ao Brasil e o preço também não foi divulgado ainda. Resumindo As TVs QLED da Samsung possuem uma qualidade de imagem melhor e mais ângulo de visão, mas são um pouco mais conservadoras no que se refere a design. Já as novas TVs OLED da LG encantam os olhos com sua espessura finíssima e design inovador. Mesmo assim, ainda é cedo para dizer qual tecnologia levará a melhor.
Laporanitu memberi bukti lebih jauh kalau Samsung akan beralih dari panel LCD di produk TV layar QLED miliknya. Pada TV QLED, Samsung menggunakan teknologi kombinasi quantum dot filter dan LCD backlight. Berdasarkan pemberitaan yang ada, pejabat dari Samsung dan LG telah bertemu untuk mendiskusikan panel OLED. Mereka mengutip keterangan dua
QLED menjadi salah satu teknologi panel dari Samsung yang cukup bagus, ini lebih dari sekedar TV LED biasa. Walaupun kemampuannya berada di bawah di bawah teknologi OLED, TV QLED punya beberapa kelebihan di antaranya mampu mengeluarkan kualitas warna alami. Dari penamaan huruf, keduanya hampir sama, cuman beda Q dan O. Sebelum membahas perbedaan QLED dan OLED, kita jelaskan dulu tentang teknologi QLED. Apa itu QLED? Kelebihan TV QLED, Sebagus apa? QLED VS OLED, Bagus yang Mana! Kesimpulan dan Tabel Perbedaan Apa itu QLED? QLED adalah teknologi yang dikembangkan oleh Samsung untuk produk televisi berkelas mereka. Dan beberapa telah merambah ke produk monitor. Teknologi ini menggunakan Titik Quantum atau quantum dots untuk menampilkan warna. Dengan adanya filter metallic quantum dots, layar jenis QLED bisa lebih berwarna, lebih kontras, dan mempunyai kemampuan gambar HDR lebih baik saat dibandingkan dengan LED/LCD biasa pada umumnya. Intinya, konstruksi panelnya hampir sama seperti panel LED biasa, cuman bedanya QLED menggunakan bahan anorganik quantum dots yang tertanam di panel LCD-nya. Teknologi Quantum dots? Quantum dots adalah partikel semikonduktor berukuran beberapa nanometer 1 nano itu 0, mm atau satu per sejuta milimeter. Partikel tersebut bersifat optik dan elektronik atau anorganik, ia termasuk dalam senyawa aluminium, sifatnya berbeda dari partikel dengan ukuran lebih besar. Awalnya teknologi tersebut digunakan oleh Samsung sendiri. Tapi dikarenakan licensing partnership, teknologi ini juga digunakan oleh produsen lain. Sehingga kita bisa menjumpai teknologi QLED di TV merek lain seperti TCL dan Xiaomi. Kelebihan TV QLED, Sebagus apa? Berkat filter quantum dots, cahaya mampu melewati titik-titik halus dengan lebih efisien dan efektif, sehingga mampu menciptakan warna lebih luas dan akurat. Titik kuantum juga mampu mengontrol secara tepat setiap warna yang keluar. Menggantikan filter warna merah, hijau dan biru yang digunakan pada TV lama. Samsung mengklaim, TV QLED miliknya menggunakan filter baru dalam menampilkan cakupan 100% jangkauan warna DCI-P3 dengan level hitam mendalam dan HDR berkilau. Serta tetap mempertahankan kinerja, berapa pun kecerahannya. Tingkat kecerahan maksimum bisa mencapai antara 1500 nits dan 2000 nits, selagi tetap menjaga warnanya selalu akurat. Singkatnya nano partikel berukuran sangat kecil yang secara dramatis mampu meningkatkan kualitas warna beserta kecerahan pada layar. Samsung Q65R, jadi salah satu contoh TV yang menggunakan panel layar Samsung QLED 4K UHD dengan luas 43 inci. Selain itu mereka juga membuat model Samsung The Frame 50 inci atau Samsung The Frame 85 inci sebagai TV wallpaper, kemudian Samsung Neo QLED 55 inci dan Samsung the serif 50 inci, sebagai TV andalan. Itu mahal, namun beberapa dengan harga murah juga ada, seperti TV TCL QLED 43 inci q725, atau xiaomi QLED 55 inci. Panel OLED kini mempunyai saingan kuat, yaitu QLED. Masing-masing dari keduanya memiliki kelebihan dan kekurangan. Untuk mengetahui teknologi mana yang lebih baik, maka kita coba untuk membandingkan secara detail kelebihan dan kekurangan dari keduanya. Sehingga bisa memilih TV mana yang cocok menjadi pilihan. Berikut 10 perbedaan QLED dan OLED. 1. Tingkat kehitaman Warna gelap membuat gambar bisa ditampilkan seperti aslinya alami. Untuk menampilkan warna gelap, panel OLED akan mematikan piksel, sehingga tidak ada cahaya yang memancar. Tentunya tingkat kehitaman warnanya akan sangat gelap. Sementara panel QLED tidak sebagus OLED, karena dalam menampilkan warna gelap ia hanya akan menghalangi cahaya lampu sehingga layarnya masih menyisakan cahaya. Ini membuatnya tidak benar-benar hitam sebagaimana layar OLED. 2. Kecerahan Panel QLED mempunyai kelebihan dalam hal kecerahan. Mereka menggunakan lampu layar LED terpisah yang dapat menghasilkan tingkat kecerahan super tinggi. Kemampuan Quantum dots dapat menghasilkan cahaya sangat terang, tanpa kehilangan saturasi warna. Ini artinya warna yang dipancarkan akan benar-benar konsisten, sehingga kontras akan tetap baik di ruangan gelap maupun terang. QLED mampu menangani kecerahan hingga nit jika pabrikan menginginkan backlight seterang itu. Dari sisi kelebihan, kamu bisa menikmati konten HDR di ruangan yang sangat terang. TV QLED di ruangan terang dan gelap Sementara untuk layar OLED, rata-rata memiliki tingkat kecerahan 500 hingga 800 nits, itu pun tidak bisa menghasilkan warna murni pada tingkat kecerahan tinggi, setiap pikselnya tidak dapat menghasilkan tingkat cahaya yang sama. Namun, OLED masih bisa menghasilkan warna murni pada tingkat kecerahan yang tidak begitu tinggi. 3. Cakupan warna QLED bisa lebih bagus ketimbang OLED; dalam hal akurasi warna, kecerahan warna, dan volume warna. Menurut Samsung, QLED memiliki jangkauan warna yang luas dengan saturasi terbaik, serta dapat mencapai tingkat kecerahan lebih tinggi. Tampilan QLED memiliki nada lebih hangat daripada jenis tampilan lainnya, karena titik kuantum merah dan oranye lebih besar daripada biru dan hijau. Cakupan warnanya juga sangat luas hingga 84% dari Rec. 2020, sementara OLED umumnya sedikit lebih rendah dengan rentang 75% dari Rec. 2020. 4. Waktu Respons Waktu respons, waktu yang diperlukan untuk beralih dari satu kondisi ke kondisi lainnya. Bisa dibilang ini adalah waktu yang dibutuhkan untuk pergantian warna. Semakin cepat prosesnya, gambar yang dihasilkan akan semakin tajam ketika ada gerakan atau smooth halus, dalam istilahnya ini disebut motion blur. Waktu respons QLED bervariasi, antara 2 sampai 8 mili detik mirip dengan standar panel LED pada umumnya, namun OLED lebih cepat dengan 0,1 atau mili detik ini sangat cepat. Namun ketika dilihat sebagai TV, tampilannya akan sama saja dan tidak menunjukkan perbedaan. Jadi memilih yang mana saja tidak masalah. Kecuali untuk sekelas monitor gaming pro, yang mencari motion blur rendah. Refresh rate, pergantian atau memperbarui tampilan layar di setiap detik. Normalnya TV menggunakan kecepatan Refresh rate 60Hz, untuk yang lebih canggih ada 120Hz. Setiap TV memiliki Refresh rate bervariasi, dan semua dapat diterapkan di kedua panel tersebut. 5. Sudut pandang wide viewing angle Layar QLED akan tampak baik saat dilihat dari depan. Dan ketika bergeser semakin ke sisi samping atau atas dan bawah kualitas gambarnya akan terlihat berkurang dan berubah, baik dari segi warna maupun kontras. Walau sudut pandangnya telah sedikit ditingkatkan dengan menambahkan lapisan anti-reflektif, tetap tidak dapat menandingi OLED. Jadi OLED masih lebih baik jika dilihat dari sudut mana pun. 6. Ukuran Awalnya OLED hanya bisa untuk layar dengan ukuran 55 inci, kemudian 88 inci. Tetapi QLED bisa lebih dari itu, karena saat itu Samsung telah mengeluarkan dengan layar lebih luas, yang bisa mencapai 98 inci 8k. 7. Masa pakai TV QLED memakai backlighting led, yang pada dasarnya memiliki masa pakai lebih lama, atau bisa dibilang ini lebih awet. Kemudian bahan anorganik baru berbentuk Quantum Dots, memberikan ekspresi warna konsisten dalam jangka waktu yang panjang. Sedangkan TV OLED memiliki umur lebih pendek. Untuk berapa lamanya dapat bertahan, itu tergantung pemakaian. Selain itu, bahan organik yang digunakan dapat memudar seiring bertambahnya waktu. 8. Layar Burn-in Layar burn-in atau terbakar. Masalah ini membuat perubahan warna permanen pada layar. QLED dengan titik Quantum anorganik tidak mengakibatkan burn-in, bahkan di tingkat kecerahan maksimum. Jadi ia lebih tahan dari masalah burn-in. Sedangkan OLED cenderung rentan terhadap burn-in, karena di kombinasikan dengan bahan organik. Ia akan cepat mengalami burn-in apabila menyala dengan kecerahan tinggi yang menyebabkan panas berlebihan. 9. Konsumsi daya Teknologi QLED mirip dengan panel lain seperti panel LED pada umumnya, menggunakan backlight di belakang panel untuk memancarkan cahaya. Seperti yang diketahui itu membuatnya lebih boros daya. Panel OLED itu ringan dan tipis. Setiap pixel pada panel OLED dapat menyesuaikan kecerahannya sendiri, membuatnya lebih efisien dengan mengonsumsi daya lebih sedikit. Terutama jika gambar yang ditampilkan tidak selalu cerah, atau cenderung banyak gelapnya. Intinya konsumsi daya panel OLED menyesuaikan konten yang sedang ditampilkan. 10. Harga Meski teknologinya lebih baru, biaya pembuatan panel QLED lebih murah dibandingkan OLED. Kita tahu keduanya punya kualitas yang sama-sama premium. Penyebab OLED bisa mahal dikarenakan proses pembuatan panelnya yang sulit, dengan kisaran harga 30 hingga 50% lebih mahal dibandingkan QLED.

Qled adalah teknologi panel layar yang menggunakan bahan anorganik quantum dot berukuran nano untuk memfilter cahaya LED. Qled TV adalah TV yang menggunakan teknologi quantum dot yang dikembangkan oleh Samsung. Perbedaan qled dan led Cara kerja keduanya sama, namun QLED menggunakan partikel quantum dot untuk mengelola warna.
PhilipsOLED805 juga memiliki kedalaman (volume) 5,8 cm. Bandingkan dengan Sony A8 yang 5,2 cm dan LG CX yang 4,7 cm. Mungkin mengejutkan, Q90T QLED Samsung mengalahkan semua OLED ini dengan hanya setebal 3,5cm, tetapi ketebalannya sama di semua titik. Tidak ada bagian super tipis seperti pada saingan OLED-nya.

Hence, QLED and OLED are causing some consternation among shoppers, and among some online reports, about what the differences are and which technology is superior.Image credit Tom's Guide/LGSince Samsung's QLED TVs came on the scene in 2015, the technology has improved and expanded to other brands, including several of the best TVs. The refinements of the last several years have made it harder to spot the difference in more premium TVs, narrowing the gap between expensive OLED sets and the sometimes more affordable QLED TVs on the market. And as more manufacturers offer quantum-dot-enhanced displays, the confusion between the two technologies will only tested the leading models, including the Samsung Q90 $2,499 and LG C9 $2,796, and cut away the jargon to set the record straight about QLED and OLED technology – and tell you which is are the players?QLED is an abbreviated form of "quantum-dot LED," and while the term is most closely associated with Samsung TVs – as seen on high-end LCD TVs like the Q90 – the technology and QLED name is by no means proprietary. Quantum-dot technology has been around since 2013, and many manufacturers are already using it on new 4K TVs, including Hisense, TCL and Vizio, in addition to sets are essentially a modification or addendum to conventional LCD TVs, which represent the majority of TVs on the Bravia OLED XBR-65A1E OLED stands for organic light-emitting diode, a very different way of creating a picture. The only company currently making large-panel OLEDs for TVs is LG, which offers a variety of OLEDs, including the LG C9 OLED OLED65C9PUA. Other companies with OLED TVs, such as Philips, Panasonic and Sony – including the Master Series A9F – use LG's do they work?Quantum-dot, or QLED, sets use a conventional LCD liquid-crystal display to which they add another layer of quantum dots of a particular size, which in turn dictates the color those dots emit when hit by light from behind. By adding the extra quantum layer, extra colors a wider color gamut can be displayed.Image credit QLED uses a layer of nano-sized quantum dots that emit particular colors when lit. Credit SamsungHowever, quantum-dot LCDs still require a separate backlight to illuminate the display. That light is created by LEDs behind the panel or along its edge, hence the "LED" part of Samsung's acronym. While there are a handful of TVs on the market that use LEDs for display and color, namely Samsung's MicroLED sets, they are far from mainstream, and LED TVs for the moment almost exclusively refer to LCD sets with LED backlighting.Image credit LCD panels require a separate backlight to illumnate the display. Credit LGLG CX OLED vs. Samsung Q90T QLED Which should you buy?OLED, or organic light-emitting diode, represents a completely different kind of display. No backlight is required because the organic pixels emit their own light when activated. So each pixel can be completely turned on or off separately.Image credit OLED panels can turn each individual pixel on and off. Credit SonyWhich is sharper?In technical terms, OLED is theoretically sharper because it can turn on or off each individual pixel. With quantum-dot sets, because there's an afterglow and light leakage behind the LCD layer caused by the separate backlight, it tends to blur the edges around bright or local dimming on LCD sets helps, but some light leaking still occurs. Consequently, we still commonly see halo effects around bright objects displayed on LCD sets from manufacturers ranging from Samsung to OLEDWhich delivers deeper blacks?When it comes to crisp, clear details and accurate picture reproduction, a key element is the display's black levels. Deeper blacks allow for a sharper-looking picture and a more realistic viewing experience. And when it comes to black levels, there is no debate OLEDs are the only sets that can deliver true LCDs – including Samsung's QLEDs – look grayish next to an OLED set. The backlighting system necessary to make LCD and quantum-dot LCD sets work means it is virtually impossible to completely eliminate light leakage. The result is a glowing grey called "elevated black," and depending upon the set, it can extend a centimeter or two around any bright object on the screen, or even cover the screen from corner to corner. The more premium the TV, the better the black levels, but it's a problem we see on even the best QLED OLEDWhich is brighter?Quantum-dot LCD sets, including Samsung's QLEDs, are brighter than OLEDs. They simply put out more light, making them more appropriate for sunny rooms where brightness counts.Image credit QLEDs like this Samsung offer more brightness. Credit SamsungCompare, for example, our recent brightness test results from an LG C9 with 412 nits to our results from Samsung's Q90 with 1,896 nits. On the other hand, if you tend to watch movies in a dimly lit room, OLEDs can seem brighter because of their more pronounced contrast QLEDWhich has better color?Overall, a well-designed quantum-dot LCD or QLED TV can deliver a wider range of colors than an OLED set. They can also be more accurate, with more faithful reds, for example. But the gap between the two technologies is narrowing, with LG's technology division putting some serious R&D behind improvements to OLED color recent tests, the LG C9 OLED earned a Delta-E color accuracy score of compared with Samsung's Q90 quantum-dot TV, which had a score of lower is better. While the Samsung edged slightly ahead, both offer superb color accuracy.Image credit QLED TVs generally deliver a wider range of colors. Credit SamsungNevertheless, how wide a color gamut or how many colors a display can reproduce still varies from set to set. Some OLEDs, such as Sony's Master Series A9F, can match or best quantum-dot sets in this regard. Recent Tom's Guide tests showed that the Sony OLED, for example, was able to produce % of the Rec. 709 color spectrum, while Samsung's QLED reproduced of the same color video content may not reveal the differences, but as more HDR 4K programming becomes available, the nuances will be easier to TieWhat about contrast?While quantum-dot LCDs struggle with inky blacks, they tend to do better at eliciting the subtle changes between dark and light areas. Overall, top quantum-dot or QLED sets have a wider contrast range and can reveal some picture details OLEDs Your Guide to Cable TV Cord-CuttingConversely, it may look to one's eye that OLEDs deliver better contrast because of the striking differences between light and dark areas. However, OLEDs' contrast range is limited to a narrower-frequency range; as it approaches black, an OLED tends to cut off the light completely, eliminating some shadowy picture details in the process. The result is that dark grays and other near-black shades simply disappear into an undifferentiated, inky mass, an effect known as "crushed blacks."Winner QLEDWhat about viewing angles?Most of us don't sit dead center in front of the TV. We're usually at one end of the couch or the other, which means we're looking at the set off-axis. When viewed off-center, LCD TVs such as Samsung's Q60 QLED sets tend to lose some of their luster; colors look washed out or even strangely skewed. On the other hand, OLEDs such as those from LG and now Sony do not suffer from such shortcomings at least not nearly to the degree that LCDs do.Image credit SamsungSamsung's QLED is definitely an improvement in terms of viewing angles over previous generations of quantum-dot sets and most LCDs. However, LG's OLEDs are still far superior in this regard, holding their images, colors and crispness even if you are sitting a little askew in your bean bag OLEDWhat about burn-in?QLED sets come with the same advisories as OLEDs about burn-in and the dangers of letting a static picture sit on the screen for too long just look in the owner's manual. Personal experience indicates that OLEDs seem slightly more susceptible to the problem, especially in the short term, where the ghost of a logo or other icon may appear to linger a minute or two longer on an OLED than on most LCD TieOverall Winner OLEDSo which is better, QLED or OLED? The differences between the two technologies get smaller every day, with QLED TVs getting better black levels and more precise backlight control, and OLED sets boosting the overall brightness and offering more accurate black levels. But put a QLED set side by side with an OLED TV, and you'll see the reality quantum-dot-enhanced TVs can offer a great and slightly more affordable alternative to OLED, but if a pristine picture is what you want, OLED is the way to said all that, our own Kate Kozuch reckons 2021 was the year QLED finally beat OLED; that's down to how Samsung's Neo QLED took on LG's OLED evo.
