Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a first display module and a second display module positioned on the light emitting side of the first displaymodule, wherein the second display module is a transmission type display module; the first display module is used for modulating a ray which is irradiated to the second display module; the first display module comprises a plurality of first pixel units which are in array arrangement; the second display module comprises a plurality of second pixel units which are in array arrangement; and at leastone layer component between each pixel unit and each second pixel unit has a light diffusion function. At least one layer component between each first pixel unit and each second pixel unit is specially processed to enable the layer component to have a light diffusion function, so that the ray is emitted to the periphery by each angle, the original spreading direction of the ray is changed, the generated ray can more favorably break a graph generated by a periodic optical grating structure, and therefore, Moire fringes are eliminated.

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] Local Dimming refers to dividing the backlight of the display panel into multiple areas. When displaying images, adjust the brightness of the backlight in each partition at the same time according to the needs of the display screen, so as to achieve energy saving and enhance image quality. purpose. The display device used at this stage uses direct-lit backlight and increases the number of point light sources to increase the number of backlight zones. However, this method is limited by the size of the point light source, but the large increase in the number of light sources will also lead to a large increase in the drive circuit. The increase requires a higher-precision production level, which increases the production difficulty and production cost, and also increases the thickness of the whole machine. [000...

Problems solved by technology

However, such a display device structure brings new problems, that is, the repetitive pixel structure in the upper and lower display panels, due to the periodic grating pattern with similar spatial frequency, undergoes various effects such as shading effect, diffraction effect and interference effect. Function, moiré fringes will appear during image display, which will affect the display effect
