The display device further comprises a backlight module 05, wherein the backlight module 05 can provide backlight corresponding to the sub-field sequence for the liquid crystal display panel;
the optical splitting module 06 is configured to inject light corresponding to display data into the first display panel or the second display panel, so that the first display panel or the second display panel forms a monochrome gray-scale image corresponding to the display data, where the display data is pixel driving data required by a subfield sequence;
the light mixing optical module 07 is configured to mix the monochrome gray-scale images corresponding to the sub-field sequences to obtain a target color image, so that the display device displays the target color image.
It is understood that the manner in which the liquid crystal display device implements color display is classified into a color filtering method and a color field sequential display method. In a liquid crystal display device using a color filtering method, each pixel unit of a display panel is divided into three sub-pixel units, and color filters of corresponding colors are provided for each sub-pixel unit, and light emitted from a backlight source is transmitted to red, green and blue color filters through liquid crystals, thereby forming a color image. In a liquid crystal display device using a color field sequential display method, RGB light sources are arranged in each pixel unit instead of decomposing the pixel unit into three RGB sub-pixel units. And the red, green and blue primary lights emitted by the RGB light source are sequentially emitted through the liquid crystal in a time-sharing mode, and the liquid crystal molecules corresponding to the pixel units are correspondingly controlled to deflect a preset angle in a time-sharing mode, and the gray scales of the corresponding R, G and B primary lights are corresponding, so that the afterimage effect is used for displaying the color image.
In this embodiment, the display panel is driven by a color field sequential display method.
Because the conventional color field sequence display method writes pixel driving data corresponding to the color component diagram into the liquid crystal display panel in the sub-field sequence, after the pixel driving data writing is completed, the liquid crystal in the liquid crystal display panel is driven and moves to the position corresponding to the color component diagram; and then controlling the backlight module to start the backlight with the color corresponding to the sub-field sequence so as to realize the display of the color component diagram in the corresponding field sequence. However, the writing process of the pixel driving data may result in a shorter time for turning on the backlight, which may affect the overall display brightness and color gamut.
Fig. 2 is a timing chart of color field sequential display of a conventional display panel, and as shown in fig. 2, a frame of color display is divided into three sub-field sequences of RGB, and a completed frame of color display is formed by overlapping the three sub-field sequences. Each frame of the sub-field sequence can be divided into three phases: writing data, turning over liquid crystal, and emitting light by backlight; with the current higher and higher requirements of people on display resolution, the data writing amount will become larger and longer, so that the time of writing data becomes longer and longer, which compresses the time of backlight light emission, and the actual duty ratio of display light emission becomes smaller, thereby influencing the realization of high brightness and high color gamut of the display.

the light mixing optical module is used for adjusting the adjustable light mixing reflecting surface to be parallel to the second light mixing reflecting surface in the first sub-field sequence stage, so that first light passing through the second display panel sequentially passes through the second light mixing reflecting surface and the adjustable light mixing reflecting surface to be reflected to a screen of the display device, and a first monochromatic gray-scale image is formed;
the light mixing optical module is further configured to adjust the adjustable light mixing reflective surface to a position parallel to the first light mixing reflective surface in the second subfield sequence stage, so that a second light ray passing through the first display panel sequentially passes through the first light mixing reflective surface and the adjustable light mixing reflective surface and is reflected to a screen of the display device, and a second monochromatic gray-scale image is formed;
the light mixing optical module is configured to adjust the adjustable light mixing reflective surface to a position parallel to the second light mixing reflective surface in the third subfield sequence stage, so that a third light ray passing through the second display panel sequentially passes through the second light mixing reflective surface and the adjustable light mixing reflective surface and is reflected to a screen of the display device, and a third monochromatic gray-scale image is formed;
The light mixing optical module is used for enabling the first monochromatic gray scale image, the second monochromatic gray scale image and the third monochromatic gray scale image to be mixed to form a target color image, and enabling a screen of the display device to display the target color image.
