WitsView said OLED TV shipments have outperformed this year thanks to Sony and other international brand responses. On the other hand, QLED TV operators such as Samsung, TCL and Hisense have encountered major hurdles in the promotion of high-end markets due to pricing issues Although organic materials in OLEDs have color fades, residual image may appear after prolonged use, which has been criticized for a long time, but the extent of current LCD panel specifications has been very limited. OLEDs, however, The overall thickness of the machine is continuously optimized so it is attractive to international brands.
Although the QLED camp constantly emphasizes that color saturation is better than OLEDs and there is no problem of service life, QLEDs are not commercialized at this stage due to the poor external quantum efficiency and long-term inability to emit light, so the real self-luminous QD displays are still difficult to achieve commercialization. QLED camp will continue to QD backlight products to fight, that is, the backlight is covered with a layer of quantum dots covered film, commonly known as QDEF, through the LED light to stimulate the quantum dots in order to achieve high saturation effect.However, due to Backlight is an essential component that increases the overall thickness of a machine and is therefore more disadvantageous than OLED TVs, so a new generation of QLED TVs may use glass light guide solutions to reduce the thickness.
In addition, price positioning is also QLED TV this year, a big problem to 55-inch 4K TV, for example, OLED TV and QLED TV, the retail price of only about 100 US dollars, but in recent years in LG Electronics and SONY and other major manufacturers fueled Under the OLED TV in the minds of consumers has become synonymous with high-end television, so QLED TV pricing too high but will affect the purchase intention.
WitsView pointed out that QLED camp looking forward to the next generation technology such as QD CF or QD self-luminous displays, there are still technical bottlenecks to be overcome, the fastest production time also falls after 2020. However, at this stage OLED due to Technology limitations, the highest resolution can only reach 4K; the contrary, QD backlight is currently no resolution limit, so for the QLED camp, the development of the 8K television may have the opportunity to allow QLED in the high-end TV market to regain competitiveness.
