Since this year, a large number of enterprises and capital into the field of OLED, pouring from the upper panel to the downstream machine, OLED each link were showing explosive growth. In domestic manufacturers, skyworth, konka, changhong have begun production organic 4 k OLED TV, and launch series products; In the foreign manufacturers, LG, panasonic, philips also successively into the field of OLED.
In the display market, there are many compares the contents of OLED TV and quantum dots. Who is the better display technology has become a concern of the industry. Learned, quantum dots TV is selling products on the market at present is not comparable to OLED, because the technology products for LCD, still need to back light to shine on the principle of just stick a quantum dot film on the LCD backlight components, although improved the color gamut, but increases the cost, reduces the light transmittance, instead, on the expression of a few color more expansion is not natural. And the quantum dot film being limited by the material temperature, application scope is limited. Spontaneous and OLED USES mature light OLED technology, can control each pixel, so has the perfect black and accurate color performance, wide visual Angle, image is clear, at the same time there is no back light.
Is developing the future of the quantum dots - QLED more advanced some TV technology, QLED light-emitting principle similar to OLED. But QLED huge and complex system development process, the formal QLED TV commercial need 4-5 years of time. The OLED display technology has entered the market for many years, the technology more mature at the same time, the market performance and public preference have advanced performance significantly.
The advantages of OLED, no doubt, but I still have questions about, the ghosting, life often mentioned, yield and other issues. In fact, the "bottleneck" of OLED are on the market is already solved. According to LG Display OLED phase division President lu DE, the life of the current OLED products have can ensure that in 50000 hours, if watch eight hours a day, can be used more than 17 years. In addition, for the question of "echo" problem, OLED panel also through quality improvement algorithm and improved component characteristics fully solved, now can guarantee 10000 hours also won't appear the phenomenon of shadow.
If being rate, the yield of liquid crystal panel development initial period less than 50%, after ten years of 80%; And 2 k OLED panel only two years to reach 80% of the roa, the development speed is unable to catch up with the LCD panel. As a result, the so-called OLED bottlenecks or defects, now has been completely solved, it also provides great impetus to the development of OLED industry.
