EPSON OLED once again lead the technology to meet the challenge

If most of the attention of consumers has been fully focused on the LCD, PDP and other flat-panel TVs, it shows that the industry stakeholders are more concerned about the next step in the development of flat panel display core technology. OLED (organic light emitting diode) since its birth in 1979 Kodak laboratory, has been considered to be the next generation of display technology, the most powerful competitors, will fully occupy our vision in the future. But as the day before SHARP, Samsung and other companies released a concept of new LCD products, many people doubt on OLED, SED and other next-generation display technology in the future.

LCD counterattack

New technological advances make LCD color performance, in contrast, the thickness of the panel has been significantly improved, so that in the past the chronic illness is compensated, and let the next generation display technology of the original lead was almost equal. The mature technology and production cost advantages brought about a large number of applications. In the eyes of many people, if a new generation represented by OLED display technology can't again establish their own technological advantages, and quickly realize the low cost of products, is likely to be covered by the development of liquid crystal technologies, thus aborted.

From the technical analysis, compared with the liquid crystal technology, OLED has the characteristics of simple structure, thin thickness, high contrast, fast response, wide range of temperature adaptation and so on. The recent advances in liquid crystal technology are also aimed at these areas, narrowing the technology gap. From the production, organic luminescent material of OLED has been the subject of life, especially in the color OLED panel, three RGB uses organic light-emitting materials with different brightness, which will lead to different attenuation cycle, display color change occurs in the process of using. Previously, full-color OLED display elements in the basic life of more than 20 thousand hours, can only be used in mobile devices such as mobile phone, TV and other mainstream and cannot be applied to the field of flat-panel display (usually that TV screen display should have a life expectancy of 50 thousand hours).

OLED lead again

OLED technology to cope with the challenges? EPSON, SONY and other companies also use a series of technical progress gives the answer: OLED will continue to show themselves in the leading position on the performance, and quickly make up for lack of life, products and so on, again showing OLED as the next generation display technology represents the core position.

EPSON released the latest R & D results - the ultimate black (black ultimate (the)) OLED display system, in the life and display quality has made considerable progress. EPSON, by improving the development of light-emitting materials and the development of its own components, to solve the problem has long been plagued by the extension of the early life of the equipment failure. The service life is extended to more than 50 thousand hours, compared with the current mainstream flat-panel TV screen life basically reached the same level, can be used as a mainstream TV or display screen, greatly expand the application prospect of the OLED display system.

In addition, the advantages of OLED in the quality of the picture has also been further improved by the ultimate black. Because it is necessary to display through the backlight, LCD technology requires a lot of means to improve the ability to turn off and through the light to enhance the image contrast. Even so, the black screen appears also because the presence of total light grey surface. As a self luminous display device, OLED had a high contrast. While EPSON's ultimate black OLED can not show when the real black, or even better than the traditional self luminous technology PDP better performance. Not only black, self luminous characteristics so that the OLED can also ensure excellent color saturation in brightness is low, so that the screen from light to dark are natural color. Therefore, the ultimate black regardless of color contrast, the level is much higher than the general LCD panel, beyond the traditional flat-panel display image quality.

For the image quality is very sensitive to the application field, pure and rich black is a key measure of the quality of their display. EPSON's technological breakthrough so that the application of OLED is expected to show a new direction. In the past a lot of people are wishful thinking OLED can quickly cut into the big screen market, and LCD, PDP TV head-on confrontation. However, from the current OLED large screen and finished speed, the date of the decisive battle will continue to delay. The EPSON display of this high-quality OLED panel is expected to open a breakthrough in some professional, industry applications. In the image, publishing, automotive, high quality display and other fields, the display quality is very sensitive to the user will put aside the price factor, with OLED to improve their work efficiency or taste.

Like the EPSON show the ultimate black OLED simulation scene, a OLED screen embedded in the dashboard, showing the speed, engine speed and other information. Because of the new OLED black performance is very good, looks like a black panel display on the instrument, but also in a variety of light has a distinct effect.

SONY announced in December to start selling 11 inches OLED display from the product and panel thickness has made a breakthrough. This product can be said to be the first OLED to display equipment appearance in the market (the past is as small screen mobile devices), although the price is not low (200 thousand yen, about 14000 yuan), but its meaning and influence will be very far-reaching. The screen thickness of the product is only 3mm, far below the current level of the LCD screen, fully demonstrated the advantages of simple OLED structure.
