Multiple resistance OLED can become the main force of flat-panel TVs

For nearly two years, with LCD and plasma flat-panel TV products as a leader with increased production, substantial growth in the market, has been rapid development. Many consumer electronics manufacturers in the efforts to promote flat products, but also gradually began to explore the next generation of display technology research and development. From the recent year's research and development of flat panel display technology, OLED TV development momentum just fierce, concern.

In 08 years of American International Consumer Electronics Show (CES), Samsung, SONY and other international brands have demonstrated OLED TV products, OLED TV debut this product has undoubtedly become the absolute focus of large-scale exhibition. Samsung is relying on the 31 inch 4.3mm thin led market. However, the development and application of a new type of display technology must be restricted by various aspects. The research and development of OLED TV, the cost and the limitation of life, will be a strong resistance to the development of OLED, can become the main force in the tablet market, will also be an unknown number.

OLED TV

English OLED is the abbreviation of OrganicLightEmittingDiode, Chinese translated as "organic light emitting diode". OLED as a new generation of display technology, display technology is different from LCD and PDP, OLED is a kind of organic electroluminescent materials and organic display technology based on the structure, can provide a slimmer design, and high contrast, brightness, color reproduction range and fast response time. OLED is composed of solid structure, no liquid material, so the seismic performance is better, not afraid to fall.

OLED basic structure

OLED can be self luminous, while LCD is not light, which makes the OLED than the current LCD to screen a lot of light, and greater contrast, color performance is better. At the same time, light conversion efficiency of OLED is higher, because the current LCD need background lights lit, and OLED just need to add light when the unit was added on the power, so the voltage required for OLED ratio is relatively low, known as the LCD screen saving more low power consumption, more power saving.

Before, OLED is mainly used in digital camera, mobile phone and other devices, these devices required screens are relatively small, but the cost is quite high. Although SONY launched a 11 inch OLED TV last year, but its expensive price of about $13000, equivalent to the price of 47 inch flat screen TV, so that it can not be fully applied and universal. If the OLED technology to be fully used in large-size flat-panel TVs, technology and cost issues will become a powerful obstacle to the development of OLED.

In addition, at this stage, in addition to face OLED technology and cost, the biggest drawback facing short life is OLED, because OLED can only reach about 5000 hours, compared with present LCD can be as high as 10000 working hours is much shorter. At the same time, OLED still has a big problem, that is, the aging time is not synchronized, which means that the red, green, blue diode decay rate is different, will lead to distortion of the image of the tv. Serious lack of display technology, can not be well resolved, will not be able to climate. From the industrial point of view, OLED also has very big potential, the current OLED industry as LCD industry as competitors are more and more complex, and the order of LCD is much better, more conducive to the healthy development of this industry. Recently, the use of amorphous silicon (a-Si) TFT as an array of AM OLED development has a breakthrough development, contribute to the promotion of the OLED industry. If you can combine OLED industry expertise in coating technology, OLED packaging technology and module technology, as well as LCD manufacturers expertise in the field of TFT, is likely to be the best combination of the future display, television market.

The tablet market, although the OLED display technology and body design compared to the LCD and PDP are much better, but the OLED high cost and short life show, if not well resolved, may not be able to become the main force of a new generation of tablet market.
