Abstract

The application provides a liquid crystal display device, which relates to the field of display. The liquid crystal display device includes a light source, a first liquid crystal layer and a liquid crystal panel; the light source and the liquid crystal panel are respectively located on opposite sides of the first liquid crystal layer, and the light source is used to provide light The pixel area of ​​the liquid crystal panel is provided with a photosensitive device, and the photosensitive device is used to sense the light emitted from the liquid crystal panel and reflected by the identification object; the second liquid crystal layer is sealed in the liquid crystal panel, and both the first liquid crystal layer and the second liquid crystal layer can be in the Switching between the first state and the second state, the liquid crystal display device can realize high-precision biometric identification in the first state, and the liquid crystal display device can realize normal picture display in the second state. The present application also provides an electronic device including the liquid crystal display device, and a control method for controlling the electronic device. The solution of the present application can realize the biological feature recognition in the screen without affecting the viewing angle of the display screen.

Description

technical field [0001] The present application relates to the display field, and in particular to a liquid crystal display device, an electronic device including the liquid crystal display device, and a control method for the electronic device. Background technique [0002] At present, terminal devices with in-screen fingerprints are relatively common. The in-screen fingerprint is to build the fingerprint identification module into the display screen, and form the fingerprint identification module together in the manufacturing process of the display screen. In-screen fingerprints help to increase the screen-to-body ratio of terminal devices. However, the existing in-screen fingerprint solutions have low fingerprint recognition accuracy, which may affect the product experience. Contents of the invention [0003] The present application provides a liquid crystal display device, an electronic device including the liquid crystal display device, and a control method for the e...
