Why Pulse-Width Modulation (PWM) is such a headache

[NikoB]

LG seems to have solved it better.

Yes, LG has eliminated low-frequency PWM flicker on AMOLED TVs, but at the cost of fast burn-in and banding, ie. less dynamic range. Miracles don't happen.

By the way, LG is the only company on the planet, when you buy a laptop with its panel, you can be 100% sure that it does not flicker either on a regular pencil test or on a camera. And it will never flicker on VCOM templates (techmind.org/lcd/index.html), flickering on which leads to the prohibition of such screens by the legislation of some countries. Although the authorities (due to the civil stupidity of the population) often turn a blind eye to this. But, for example, Samsung in its internal documents admits the presence of such defects on its panels for laptops, which, in theory, should lead to a ban on sales of laptops with them, as well as panels from Innolux (most often flicker), BOE (less often but also often, especially with multi-row backlit) and AUO and lesser known brands.
