Does the Lcd screen not have high frequency pwm dimming?

The LCD screen itself does not have high-frequency PWM dimming, but needs to be achieved by the LCD controller or driver chip. Under normal circumstances, the LCD screen will use DC dimming or low-frequency PWM dimming to control the brightness to avoid visible flicker and interference. However, some high-end LCD screens or professional LCD displays may use high-frequency PWM dimming technology to obtain a more refined and smooth brightness control effect.
