Abstract

The invention is applicable to the technical field of displaying, and provides a display panel assembly and a display device. The display panel assembly comprises a diffusion film arranged on the light emitting surface of a display panel; the diffusion film comprises a first electrode, a second electrode and a diffusion liquid crystal layer clamped between the first electrode and the second electrode; and the diffusion performance of the diffusion film varies according to voltage applied between the first electrode and the second electrode. According to the display panel assembly, through thearrangement of the diffusion liquid crystal layer on the light emitting surface of the display panel, the diffusion performance of the diffusion film can be changed by adjusting the voltage, so that auser can freely adjust the diffusion performance of the diffusion film to meet different visual angle requirements; a good displayed picture can be observed under a large visual angle, and the picture still has relatively good contrast and brightness under a small visual angle; the display panel assembly considers different visual angles and the picture quality under different visual angles; andthe flexibility of visual angle adjustment and the user experience are improved.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a display panel component and a display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is a commonly used electronic device, and is widely favored by users due to its characteristics of low power consumption, small size, and light weight. [0003] LCD includes TN (Twisted Nematic, twisted nematic) mode, VA (Vertical Alignment, vertical alignment) mode, IPS (In-P1ane Switching, in-plane switching) mode, etc. according to different display modes. Among them, taking the VA mode as an example, it has become a commonly used display mode due to its advantages such as wide viewing angle, high contrast and no need for frictional alignment, but it also brings serious color shift and lower contrast at large viewing angles. Because the liquid crystal molecules in the VA mode are arranged vertically to the upper and lower glass in the dark stat...
