Abstract

The embodiment of the invention provides a display module and a display device, the display module comprises an array substrate and a liquid crystal layer, a corresponding film layer in a camera shooting area is improved, so that the thickness of the liquid crystal layer in the area and the birefringence of liquid crystal molecules in the liquid crystal layer meet the quantitative relation in the embodiment of the invention, and the effect of a polarizing film layer is further formed. When light passes through the film layer, the light reflectivity in the area can be effectively reduced, the brightness of the camera shooting area of the full-screen display panel and the brightness of other areas can reach high consistency, and the integrated display effect of a full screen is improved.

Description

technical field [0001] The invention relates to the technical field of display panel preparation, in particular to a display module and a display device. Background technique [0002] With the continuous improvement of display panel preparation technology and preparation process, people have higher and higher requirements on the performance of the prepared display panel and equipment. [0003] In recent years, with the continuous development and maturity of full-screen display panel technology, full-screen displays have been applied to many display devices. Compared with the conventional display screen, the full screen removes the black non-display area with a large proportion of the water drop screen. By setting the camera hole of the camera area directly on the display area of ​​the display screen, and through the The display effect of the corresponding film layer in the hole is adjusted, such as adjusting the transmittance of the film layer in this area to achieve a full...
