Abstract

The invention provides a display device. The display device comprises a display panel and a backlight source in laminated arrangement. The display panel comprises a color light emitting layer and a light filter layer, and the color light emitting layer comprises a red-light quantum dot area, a green-light quantum dot area and a transparent area. The backlight source is a blue-light backlight source and used for providing blue light for the color light emitting layer to enable the red-light quantum dot area, the green-light quantum dot area and the transparent area to emit red light, green light and blue light distinguishably. The light filter layer is used for absorbing part of blue light emitted by the transparent area. By the display device, blue light emitted by the transparent area can be reduced, and accordingly intensity of blue light emitted by the transparent area can be reduced to be equal or approximate to that of light emitted by other two light emitting areas, light intensity of the three light emitting areas is balanced, and display effects are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] LCD (Liquid Crystal Display) technology is currently the leading technology in the field of flat panel display due to many advantages such as low power consumption, high image quality and light weight. Quantum dots are widely used in displays because they can emit high-purity monochromatic light, which improves the color gamut and saturation of the display. Different from ordinary color film substrates, quantum dots are used in the color film layer. Quantum dots can be used for the active ingredients in the red pixel area and the green pixel area, while the blue pixel area uses organic transparent materials. The corresponding backlight Using the backlight emitting blue light, the red pixel area, the green pixel area and the blue pixel area can respectively emit red light, green light and blue light without adding other pho...
