Problems solved by technology

[0004] However, since the backlight provided by the existing backlight module is white light, and the color resistances of the red, green, and blue colors in the color layer only allow the corresponding red, green, and blue bands of white light to pass through, this When the white light passes through the color layer, there will be a considerable loss, resulting in a lower display brightness of the display device.

Embodiment 1

[0031] see figure 1 and figure 2 , the pixel unit structure provided by the embodiment of the present invention is applied to a display device, including N sub-pixels, and the N sub-pixels include a transparent sub-pixel 403 and N-1 photoluminescent sub-pixels; the backlight emitted by the backlight module of the display device Exciting the N-1 photoluminescence sub-pixels corresponds to generating N-1 primary color lights; the N-1 primary color lights and the backlight 403' realize color display.

[0032] Among them, in the display device applied to the pixel unit structure provided by this embodiment, the structure of the display panel is various, for example: please refer to figure 1 , the display panel may include a first polarizer 1, a second polarizer 2, a TFT array substrate 3 and a color filter substrate 4 arranged between the first polarizer 1 and the second polarizer 2, the TFT array substrate 3 and the color filter A liquid crystal layer 5 is arranged between the...

Embodiment 2

[0050] see figure 1 , the color filter substrate 4 provided in this embodiment includes a plurality of pixel unit structures of the technical solution provided in the first embodiment above.

[0051] Compared with the prior art, the beneficial effects of the color filter substrate 4 provided in this embodiment are the same as those of the pixel unit structure provided in the first embodiment above, and will not be repeated here.

Embodiment 3

[0053] see figure 1 The display device provided in this embodiment includes a backlight module and a display panel, and the display panel includes the color filter substrate 4 provided in the second embodiment above.

[0054] Compared with the prior art, the beneficial effect of the display device provided by this embodiment is the same as the beneficial effect of the pixel unit structure provided by the first embodiment above, and will not be repeated here.

[0055] And considering that in the existing backlight module, the light source is composed of a plurality of single-color LED chips, and in order to make the light source provide white mixed light, each LED chip is also covered with other LED materials. Doping contains epoxy resin and silica gel so that the LED material can be firmly covered on the LED chip, but because the LED chip will generate heat during the working process, and the LED material covering the LED chip will make it difficult to release the heat, result...

Abstract

The invention relates to the technical field of display and discloses a pixel unit structure, a colour film substrate, a display device and a display method for improving display brightness of the display device. The pixel unit structure is applied to the display device and comprises N subpixels, wherein the N subpixels comprise one transparent subpixel and N-1 photoluminescent subpixels; backlight emitted by a backlight module of the display device excites the N-1 photoluminescent subpixels to correspondingly produce N-1 primary light; and the N-1 primary light and the backlight realize colour display. The colour film substrate comprises multiple pixel unit structures provided by the technical scheme. The display device provided by the invention is applied to the technical field of display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel unit structure, a color filter substrate, a display device and a display method. Background technique [0002] A display device is a device that visualizes digital signals, and generally includes two parts: a backlight module and a display panel; among them, the backlight module provides backlight for the display panel, and the display panel processes the backlight to form a visual image . [0003] In order to colorize the image, a color filter substrate is provided in the display panel, and the color filter substrate includes a color layer composed of a plurality of pixel units; each pixel unit is generally composed of three color resists of red, green and blue. In this way, after the backlight emitted by the backlight module passes through the color layer of the color filter substrate, it will be colored by each sub-pixel in each pixel unit in the color layer, so that...
