Abstract

The invention relates to the field of liquid crystal display, in particular to an image display method, device, equipment and storage medium of a cholesteric LCD, which are used for acquiring complete frame data from a video interface, storing the complete frame data into a target bit half area of a memory, comparing a high bit half area with a low bit half area address by address, judging whether the data of the high bit area and the low bit area in the same address are the same, and sending the complete frame data to a cholesteric LCD image processing assembly when the number of different addresses of the data of the high bit area and the low bit area exceeds a preset trigger threshold value and taking a non-target bit half area in the high bit half area and the low bit half area as a new target bit half area. The complete frame data with small difference in the invention can not be sent to the cholesteric LCD image processing component for display at all, thereby reducing the display pressure of the cholesteric LCD, realizing effective image transmission, comparing only by reading the address once and saving the processing time.
