From mobile phones to tablets to laptops, major consumer electronics with screens are increasingly using OLED panels.

In the field of TV, OLED still exists, but with the promotion of major giants such as LG, Samsung and Sony, popularity is just a fake.

But just like the screen burning phenomenon of OLED on mobile phones, it can't be avoided completely on large-size TVs, which has sparked a war of words between Samsung and LG, two major Korean brands.

A few days ago, LG said it learned from the testing agency Rtings that Samsung's QD OLED TV panel is easier to burn than LG Display's WOLED. The strange thing is that Rtings has not yet released the test results.

According to LG, the Samsung QD OLED uses the traditional RGB sub-pixel arrangement, which will result in a shorter life than its own WOLED, which means it is more likely to burn the screen.

It is reported that the essential reason for burning the screen is that the lifetime of RGB sub-pixels is different. in order to extend the life, LG's WOLED scheme is to add White (white) pixels to improve brightness; Samsung launched QD OLED last year by adding a blue self-luminous layer after the quantum dot layer to brighten.
