AI Technical Summary

Technical Problem

Existing liquid crystal display panels have high light loss and energy consumption during the light emitting process, and are prone to color separation, which affects the display effect.

Method used

Using field-sequential display technology, the liquid crystal display device receives initial grayscale data in multiple primary colors in the first working mode, filters out target pixels and non-target pixels, and determines the actual grayscale of the target pixel according to certain conditions. The average value of non-target pixels reduces the contrast, thereby weakening or eliminating color separation, and uses different color light-emitting devices in the backlight module for display.

Benefits of technology

Without increasing power consumption, it can improve light extraction efficiency, reduce color separation, improve display effects, and improve picture smoothness.

Abstract

The invention discloses a liquid crystal display device, an image display method, electronic equipment and a readable storage medium. In a first working mode, a control circuit of the device receives display data of an mth frame of image, and controls the device to display n sub-field images to obtain the mth frame of image; the display data comprises initial gray scales under n primary colors; in one sub-field image of the mth frame of image, pixels comprise a target pixel, and the actual gray scale of the target pixel is an average value of the middle gray scale and the initial gray scales of T non-target pixels; the actual gray scale of at least part of non-target pixels is the initial gray scale; the target pixel at least meets one of a first condition and a second condition; the first condition is that the distance between a target point reflecting the color of the target pixel in the reference color space and a white point is smaller than a distance threshold value; the second condition is that the reference brightness of the target pixel is greater than a brightness threshold; and / or the contrast ratio of the target pixel is greater than a contrast ratio threshold value.
