AI Technical Summary
Technical Problem
The existing LCD display panels have high light loss, high energy consumption, and are prone to color separation during the light output process.
Method used
By adopting a plurality of backlight regions in the liquid crystal display device, each backlight region contains light emitting devices of n colors, and receiving the initial image in the first working mode through a control circuit, the liquid crystal display panel is controlled to display n subfield images in sequence to reduce color separation phenomenon.
Benefits of technology
On the premise of reducing power consumption and improving resolution, color separation is reduced and light output efficiency is improved, avoiding the necessity of using color films in display technology.

Abstract
A liquid crystal display apparatus, an image display method, and an electronic device, which relate to the field of display. The liquid crystal display apparatus comprises a liquid crystal display panel and a control circuit (CU). The liquid crystal display panel comprises a liquid crystal display substrate (PNL) and a backlight module (BLU). The liquid crystal display substrate (PNL) comprises a plurality of pixels. The backlight module (BLU) comprises a plurality of backlight regions (BA), and each backlight region (BA) comprises light emitting devices of n colors. The control circuit (CU) comprises a first working mode, and is configured, in the first working mode, to: receive an mth frame of initial image, and control each liquid crystal display panel to sequentially display n different sub-field images to obtain an mth frame of actual image, wherein m and n are positive integers, and n≥2. The initial image comprises initial color information of each pixel. The initial color information of one pixel comprises an initial grayscale under n tones. In one sub-field image, the backlight regions (BA) comprise a first backlight region (BA1) and a plurality of second backlight regions (BA2). The tones of light emitted by the first backlight region (BA1) and the second backlight regions (BA2) are different, and the tones of the light emitted by the second backlight regions (BA2) are the same.
