Embodiment Construction

[0031] The present invention provides a display screen through the embodiment of the application, which is used to solve the technical problem in the prior art that the display screen can only display image information based on the display light source provided by the light source layer, but cannot display image information based on ambient light.

[0032] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0033] A light source layer, when the display screen is in the first display mode, the light source layer is turned on to provide a display light source corresponding to the first display mode, and when the display screen is in a different display mode from the first display mode In the second display mode, the light source layer is in an off state; the liquid crystal layer is placed in front of the light source layer; the polarizer is placed in front of the liquid cryst...

Abstract

The invention provides a display screen and a piece of electronic equipment. The display screen comprises a light source layer, a liquid crystal layer, a polarizer and a control unit. When the display screen is in a first display mode, the light source layer is open to provide a display light source corresponding to the first display mode; and when the display screen is in a second display mode different from the first display mode, the light source layer is closed. The liquid crystal layer is disposed in front of the light source layer. The polarizer is disposed in front of the liquid crystal layer. The control unit is connected with the liquid crystal layer and used for controlling the liquid crystal layer. When the display screen is in the first display mode, the liquid crystal layer, under control of the control unit, enables the optical phase of polarized light passing through the liquid crystal layer and corresponding to ambient light to rotate from a first angle to a second angle meeting a first preset condition; and when the display screen is in the second display mode, the control unit controls the liquid crystal layer so as to control the optical phase of the polarized light to rotate from the first angle to a third angle meeting a second preset condition.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a display screen and electronic equipment. Background technique [0002] Display screens in the prior art use advanced materials, such as Organic Light-Emitting Diode (OLED), which is a recently emerging self-luminous display technology. OLEDs do not require a backlight source due to their simultaneous self-luminescence. , high contrast, thin thickness, wide viewing angle, fast response, can be used for flexible panels, wide operating temperature range, simple structure and manufacturing process, etc., are considered to be the next generation of emerging application technologies for flat panel displays. However, due to the design of the OLED's own structure, its metal cathode reflectance is extremely high, so the OLED display strongly reflects ambient light, so its display effect is not satisfactory. [0003] In the prior art, in order to solve the above-mentioned technical ...
