Abstract

The invention discloses a display assembly and a rearview mirror display screen, and relates to the field of display screens. The display assembly comprises a cholesteric liquid crystal layer, a quarter-wave plate, a linear polarizer and a display module which are sequentially stacked, under the condition that the cholesteric liquid crystal layer is powered on, display light emitted by the display module sequentially penetrates through the linear polaroid, the quarter-wave plate and the cholesteric liquid crystal layer, so that the display assembly has a display function. Under the condition that the cholesteric liquid crystal layer is powered off, display light emitted by the display module sequentially penetrates through the linear polarizer and the quarter-wave plate and is reflected on the side, facing the quarter-wave plate, of the cholesteric liquid crystal layer, and ambient light is reflected on the side, deviating from the quarter-wave plate, of the cholesteric liquid crystal layer. The rearview mirror display screen comprises the display assembly. The problems that the contrast ratio of a displayed image is poor, negative influences are caused to a driver wearing a polarized lens, and the cost of a current reflection type polaroid is high can be solved.

Description

technical field [0001] The present application belongs to the technical field of display screens, and in particular relates to a display assembly and a rearview mirror display screen. Background technique [0002] Adding a display screen to a car rearview mirror is one of the trends in vehicle design in recent years. Its main application is to integrate a driving recorder into the rearview mirror, and it can also be used to display reversing images. Currently, the rearview mirror display adopts a backlight display method, and its display module is located behind the lens; when the image is not displayed, the display module is turned off, and the rearview mirror display is used as a rearview mirror. [0003] The current car rearview mirror adopts such as figure 1 with figure 2 In the design shown, the ambient light passes through the reflective polarizer 02 and reflects the light of polarization state 1 to act as a rearview mirror; the reflective polarizer 02 can emit ligh...
