Technical interest double conflict OLED TV universal difficulty

Speaking of "LED TV," I am afraid that many people are not unfamiliar. LED TV advertisements in the electronics store are everywhere. However, the LED TV I talked to here is exactly an OLED TV. Now, what is known in the market as "LED TV" is actually It is still a traditional LCD TV, but only the backlight system has been replaced with CCFL lighting and LED lights.

Speaking of OLED TVs, it seems that many people feel that they are far away and seem to be still conceptual. However, some time ago, at the CES Consumer Expo, the two major Korean companies put their products on the booth so that the products did not seem so far away.

Obvious advantage of OLED OLED display uses organic light-emitting diodes (OLED) to provide backlight for the display, so the power consumption is relatively small compared to the LED display. In addition, the image quality and response speed of the OLED display are also better than the traditional LCD screen.

As an OLED TV that actively emits light at each pixel, the brightness of each point is individually controlled. Compared with LCD TVs, the backlight system has an inherent advantage in contrast, and contrast is a very important factor in the black level of the film. This is why more video players prefer plasma.

In addition to its advantages over liquid crystals, the advantages of OLED power saving are incomparable with plasma. At the same time, the thickness and thinness of millimeter-level OLED TVs are far behind plasmas.

Korean enterprises are ahead of the Korean companies most concerned with OLED. According to previous news, Samsung will shift its development focus to OLED display products after splitting the LCD display business.

As early as April 2010, LGDisplay Company stated that it will invest 223 million US dollars to expand its OLED production line. According to Chap Sin, vice president of the strategy and marketing center of LGDisplay, consumer demand for OLED displays will begin to increase in 2013. By then, the price gap between OLED TVs and LCD TVs will shrink to about 30%.

Japanese and Chinese Taiwanese companies are not to be outdone. At present, Sony is already developing OLED TVs, and AU Optronics of Taiwan also began mass production of OLED displays for mobile devices in 2011, while developing OLED displays for TVs and tablets.

OLED development time is unpredictable However, OLED has so many advantages, plus several major panel giants to follow up, it seems that the popularity is on the horizon. And many people concerned have also published articles such as the words “The OLED Storm Comes”.

Yang Dongwen, CEO of Skyworth Group: OLED is a revolution in the display technology of the color TV industry. The OLED display has self-luminous properties, no backlight source, high contrast, ultra-thin, wide viewing angle, fast response, wide operating temperature range, and simple construction and process advantages. OLED TVs will enter the promotion period next year and gradually enter the lives of consumers. It will take at least two years before they enter the industrial harvest.

However, at the recent Konka Cloud TV product launch event, I interviewed Konka Group General Assistant and said that for the time that OLED replaces LCD, we used the phrase “unpredictable” with caution. One of the important reasons is that the upstream panel manufacturers are The layout and investment of the LCD industry are quite large. When it is not determined whether the benefits brought by the OLED industry can surpass the LCD, the specific promotion time is an indefinite number. What's more, both will become the game's momentum.

Indeed, the liquid crystal industry is currently investing billions of dollars in investment in a production line. For the promotion and popularization of OLEDs, it will directly affect the interests of the entire LCD industry chain, which is particularly sensitive to panel makers. Therefore, even if the technology is mature, OLED promotion will also be cautious. The SED technology that once attracted a lot of attention from the industry, and it almost disappeared afterwards, is not unrelated to this.

In addition, in the control of cost and yield, the current OLED is clearly not yet resolved, compared to the LCD TV market has matured, there is no advantage in product prices, in a very long period of time, I am afraid LCD TV is still the mainstream .
