1. A display module, comprising:
a color backlight module and a liquid crystal display module stacked in sequence, wherein the liquid crystal display module comprises a liquid crystal display panel having a plurality of display subareas arranged along a column direction, and the color backlight module has a plurality of backlight subareas in a one-to-one correspondence to the plurality of display subareas and comprises a plurality of backlight sources located in each of the backlight subareas, each of the backlight sources comprising light-emitting elements of N colors, N being a positive integer greater than 1;
a driving apparatus connected to the color backlight module and the liquid crystal display module respectively and configured to sequentially execute N driving processes in response to receiving data of one frame of image, wherein an ith driving process comprises:
sequentially driving liquid crystal molecules in the display subareas to turn over, and after driving the liquid crystal molecules in each display subarea to turn over, driving a light-emitting element of an ith color comprised in each of the backlight sources in one backlight subarea corresponding to the display subarea as driven to emit light, i being a positive integer not greater than N; and
a plurality of reflective cups disposed between the liquid crystal display module and the color backlight module, wherein a cup bottom of each of the reflective cups is farther from the liquid crystal display module relative to a cup rim, and a size of the cup bottom is smaller than a size of the cup rim; wherein an orthographic projection of each of the reflective cups onto the liquid crystal display module overlaps with an orthographic projection of at least one of the backlight sources onto the liquid crystal display module.
