WitsView said that thanks to the international brand response such as SONY this year, OLED TV shipments than expected performance; the other hand, QLED TV camps such as Samsung, TCL and Hisense, due to pricing issues, in the promotion of high-end market encountered no small obstacle Although organic materials in OLEDs have the problem of color fades, image sticking may appear after prolonged use, which has been criticized for a long time. However, the current LCD panel has been limited in terms of specifications. However, OLEDs, regardless of color saturation, , And even the thickness of the machine can continue to optimize, so the international brand is still very attractive.
Although the QLED camp constantly emphasizes that it is superior to OLED in color saturation and has no problem of service life, at this stage, because of the poor external quantum efficiency, it is difficult to maintain a long time of light emission, and the real self-luminous QD display is still difficult to achieve commercial Level.Therefore QLED camp in the short term will still QD backlight products to fight, that is, a layer covered in the backlight covered with a quantum dot film, commonly known as QDEF, through the LED light to stimulate the quantum dots in order to achieve high-color full However, since backlighting is a must-have component that increases overall thickness, it is still a disadvantage compared to 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 both the retail price of only about 100 US dollars, but in recent years in LG Electronics and SONY and other manufacturers to 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 Technical limitations, the highest resolution can only reach 4K; On the contrary, QD backlight is currently no resolution restrictions, so for the QLED camp, the development of 8K television may have the opportunity for QLED in the high-end TV market to regain competitiveness.
