[0003] The current LED drive control method is the traditional passive drive control. The traditional passive drive control scheme cannot meet the requirements of Micro-LED display due to PCB layout restrictions and display fineness. Therefore, Micro-LED display needs to be driven by active TFT circuits. Well-known manufacturers and scientific research institutions at home and abroad have proposed a variety of active TFT drive solutions for Micro-LED display. However, there is no mature peripheral display control method for Micro-LED active TFT drive circuits.

[0004] AMOLED and LCD display technologies have been developed for many years, and both have mature display driver ICs and display control solutions. The Micro-LED active TFT drive circuit adopts the PAM+PWM hybrid drive method to reduce the impact of LED color deviation on the display effect under low current to meet the needs of fine grayscale display. The important part of the PAM+PWM hybrid drive method needs to generate a SWEEP comparison signal to compare with the PWM signal. During the comparison process, the LED chip emits light to display the video signal. However, there are currently no display driver ICs and display control solutions for Micro-LED on the market.
