OLED is a new generation of liquid crystal display technology compared to LCD. The biggest feature is self-illumination, which is brighter than LCD. However, due to the low yield of OLED liquid crystal screens, mass production has always had problems. In June last year, Sony and Panasonic established the OLED alliance, hoping to complete the goal of mass production by the end of this year. However, last year South Korea's Samsung and LG took the lead in launching large-size OLED LCD TV products, which have been shipped on a large scale this year. The industry believes that this is also an important reason for forcing Sony and Panasonic to abandon OLED cooperation and research and development.
In the field of 4K TV, Japanese companies such as Sony are ahead of the Korean giants. 4K TV belongs to ultra high definition resolution TV. Last year, Sony launched the 4K TV in China. In contrast, Panasonic has not had more moves in the 4K TV field.
