Abstract
The present invention relates to a cholesteric liquid crystal display, a micro processing unit, and a method for hybrid driving. The cholesteric liquid crystal display comprises a display panel and a micro processing unit. First, a grayscale threshold value needs to be set in advance. The micro processing unit will change the grayscale value of the display unit exceeding the grayscale threshold value to the new grayscale value displayed by the bright state color, and display the image by the DDS driving mode. Then the micro processing unit drives the display image in the PWM drive mode, which can greatly improve the color level and contrast display effect of the image.
