Problems solved by technology

However, the exemplary light-emitting layer usually emits unevenly, has low light source utilization efficiency, and narrow color gamut, so that the displayed color of the sensed image is single and the display quality is poor, thereby reducing user experience.
[0003] Therefore, the exemplary image display panel has the problem that the displayed color of the sensed image is single and the display quality is poor due to uneven light emission, low light source utilization rate, and narrow color gamut.

Abstract

The invention relates to a display panel and a display device. The display panel comprises a control backboard, a light-emitting unit, a packaging layer and a light sensor array, wherein the light-emitting unit comprises a quantum dot film layer. Because the quantum dot film layer can be excited to generate light with different wavelengths to control the color effect, the utilization rate of a light source is improved. The quantum dot film layer comprises a nano-porous frame and quantum dots arranged on the nano-porous frame, so the arrangement condition of the quantum dots and the size of thequantum dots can be adjusted and controlled in order through the nano-porous frame, and the quantum dots are more uniform, stable and ordered, so as to adjust and control the light-emitting spectrum,color arrangement and color uniformity, widening the color gamut, and achieving a better color display effect. Therefore, the light sensor array is combined with the quantum dot film layer, and a sensing image with higher quality and richer colors can be obtained.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the continuous development of image sensing technology, people have higher and higher requirements for image display effects. A display panel for image sensing is usually provided with a light emitting layer to provide a light source for image sensing. The luminous quality of the luminous layer affects the display effect of the image to a great extent. However, the exemplary light-emitting layer usually emits unevenly, has low light source utilization efficiency, and narrow color gamut, so that the displayed color of the sensed image is single, and the display quality is poor, thereby reducing user experience. [0003] Therefore, the exemplary image display panel has the problems of uneven light emission, low utilization rate of light sources, and narrow color gamut, so that the displayed color of...
