Why can OLEDs take the lead in next-generation display technology?




Looking at China's color TV industry in 2015, we can use “weak and blue” to describe it. Worryingly, the entire industry is experiencing a cold winter, and the performance of a number of companies has shown negative interest. The joy is that around the display screen of color TVs, various technologies and concepts have been launched to fight against each other and the industry has entered a stage where hundreds of flowers bloom.

Of course, a hundred flowers blossom is good, but in the end it still needs a technology that dominates the world. Just as in 2005, LCD replaced CRT TVs in full. Nowadays, this kind of technology has already begun to show, it is OLED technology.

According to the explanation of Baidu Encyclopedia, OLED (Organic Light Emitting Diode), also known as Organic Light-Emitting Diode (OLED), was discovered in the laboratory by Chinese-American professor Deng Qingyun. The OLED display technology has a self-luminous characteristic, and adopts a very thin organic material coating and a glass substrate. When an electric current passes through, these organic materials emit light, and the OLED display screen has a large viewing angle and can save electric energy.

So, why do you think OLED has become the leader in next-generation display technology? The author thinks there are two reasons. First, many domestic and foreign manufacturers have joined and followed. Second, OLED has the technological advantages that LCD TVs cannot match.

The more the merrier

Compared with laser televisions and quantum dot technology, OLED organic TVs that already occupy a certain market position clearly show a trend of "clustering." In September 2015, LG Display united with nearly 30 color TV industry upstream and downstream industry chains and research institutions such as LG Electronics, Skyworth, Konka, Changhong, Haier, Suning and Gome to jointly establish the “China OLED Display Industry Alliance”.

Recently, LG Display has announced that it has invested more than 10 trillion won, launched an ultra-large OLED production line and a flexible OLED production line of more than 9 generations, and will start production in the first half of 2018. This also means that the panel supply of OLED TVs will be further enriched, and the yield rate will be effectively improved, which is more conducive to the large-scale production of OLED TVs.

At the end of last year, Skyworth held the "OLED Future Product Summit Forum" in Shenzhen and announced the launch of a new generation of OLED organic TVs with HDR technology, which was planned for 2016 in advance. Previously, OLED organic TVs including Skyworth, LG, Konka and other brands have all been launched in volume and have been favored by high-end consumers. Changhong, Haier and other brands are also actively planning to introduce OLED organic TVs.


Samsung and Matsushita, which had announced their withdrawal from the OLED TV market, also changed their attitude toward OLED TVs. According to reports, Samsung is working on the research and development of large-screen OLED panels, introducing a new transparent and mirror-based 55-inch OLED TV display, and is expected to return to the OLED organic TV market in 2017. Recently, there is news that Samsung Display will be in OLED. An increase of 7.47 billion U.S. dollars in investment in factories and equipment; Panasonic also plans to launch 65-inch 4K OLED organic TVs in the European market.

Even Hisense, which has previously been openly opposing and rejecting OLED TVs, has recently changed its position. At the press conference for a new generation of laser theaters held by Hisense, the president of Hisense Group Liu Hongxin also changed his attitude toward OLED television. Liu Hongxin said that Hisense has never rejected OLED. Perhaps three to five years later, as long as the time is ripe and consumers like it, Hisense will do its best to promote OLED.

All the above indications indicate that, with the return of Samsung, Panasonic and other companies, as well as the follow-up of major domestic and foreign manufacturers, the confidence of OLED organic TV camp will undoubtedly increase, making OLED camps overwhelmingly in competition with other display technology schools. Win. In particular, domestic pioneer Skyworth, is expected to become a leader in China's OLED organic TV market.

Quality? Thin? What are the advantages of OLED?

Is it just because of the picture quality that a change in the era is displayed? The answer is certainly not, but it is also crucial. Of course, in addition to the excellent display quality of OLEDs, the ultra-thin, flexible, and curlable designs brought about by the self-illumination of LCDs cannot be realized by LCD TVs. This is why OLEDs have been recognized as the next generation display technology.

Judging from the quality of the picture, the TV picture strives for purity and truth. Among them, black expression is particularly important because only perfect black expression can express pure colors. As we all know, LCD TVs because of its backlight and the pixels can not be fully closed restrictions, often in the performance of dark screens show a gray light leakage phenomenon, and OLED by virtue of each individual pixel self-luminous characteristics, without backlight source, in the display black At this time, it is possible to completely turn off the light of the relevant display area and present the most realistic and natural black color.

The data shows that the black brightness of OLED organic television is only 1/176 of LCD Quantum Dot TV. In other words, the OLED organic television achieves the complete closure of the light source, and the black displayed is really pure black. At the same time, the brightness performance of OLED organic TVs also has the advantage of LCD roller compactness. The test results show that the peak brightness of the former is three times as much as the latter.

At the same time, thanks to the advantages of raw materials, OLED organic TV completely overcomes the problem of color drift and realizes an ultra-wide viewing angle. OLED TVs can enjoy the same picture colors at any angle.

In brief, in terms of display effects, the OLED panel can be truly completely black due to the pixel points that can be turned off independently, and therefore has a much higher contrast ratio than the LCD screen. In terms of response speed, the grayscale change of the LCD screen needs to pass through the liquid crystal molecules. The deflection is completed, the latter's deflection is a physical movement process, will result in different degrees of image afterimages, while the solid and without physical changes of the OLED does not have doubts in this regard, and its response speed is even more than the plasma also does not need a passive light source fast.


Of course, the advantages of OLED technology are not only reflected in the picture quality, but also can provide favorable conditions for the design innovation of flat-panel TVs. Since the backlight source is not required, the thickness of the OLED panel is lower than that of the liquid crystal panel. Therefore, the thickness of the OLED TV can be further reduced. For example, the body thickness of the Skyworth 4K OLED S9 series is only 5.27 mm. At the end of this year, Skyworth will also introduce a 1mm-thick OLED TV.

At the same time, the simple structure also allows OLEDs to achieve curved and even folded display effects by matching different substrate materials. For example: curved TV, Samsung edge series and LG's GFlex series mobile phones. Only by tying up the flexibility of the circuit and other accessories, the OLED can achieve bending and even folding effects almost immediately.

Written at the end: OLED is being highlighted in mobile phones, wearable devices, etc. due to its plasticity and energy consumption advantages. It is believed that with the continuous expansion of application scale and demand, OLED organic TVs will certainly accelerate the replacement of LCD TVs. DisplaySearch once predicted that by 2018, China's OLED organic TV market will grow at a rate of about 80% annually. It is estimated that by 2020, the global OLED TV market penetration will reach 15%-20%.
