Display device

Abstract

The invention discloses a display device, comprising a plurality of pixel units, wherein the pixel units comprise a red light-emitting area, a green light-emitting area, a yellow light-emitting area,and a blue light-emitting area; the display device further comprises a blue light source and color film transparent substrates located on the light emitting side of the blue light source; the surfacesof the color film transparent substrates in the red light-emitting area, the green light-emitting area and the yellow light-emitting area close to the blue light source are respectively provided witha red filter layer, a green filter layer and a yellow filter layer; the red filter layer, the green filter layer and the yellow filter layer respectively emit red light, blue light and yellow light under blue light illumination; a transparent material layer is disposed on the color film transparent substrate in the blue light-emitting area; and the surfaces of the color film transparent substrates among the red light-emitting area, the green light-emitting area, the yellow light-emitting area, and the blue light-emitting area close to the blue light source are provided with black matrixes. The technical solution provided by the embodiment of the invention expands the display color gamut of the display device and improves the utilization rate of light emitted by the light sources.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display device. Background technique [0002] With the continuous development of display technology, display devices are widely used in various fields of social life. [0003] The display device in the prior art includes sub-pixels of three colors of red, green and blue, the display color gamut is relatively small, the picture color purity is low, especially black is more obvious, and the degree of reduction to yellow and gold is low. In addition, the light source of the above-mentioned display device is white light, and the light color conversion is realized through the color filter layer, but the color filter layer absorbs a large amount of light energy, thereby making the utilization rate of the light emitted by the light source low. Contents of the invention [0004] The invention provides a display device to expand the display color gamut of the display...
