Embodiment Construction

[0031] As mentioned in the background, the display device in the prior art has the technical problem that the non-fingerprint recognition area is prone to flicker or sudden change in brightness during optical fingerprint wake-up. The inventor found that the reason for this problem is that the current display device turns on the highest brightness in all areas of the screen to ensure the accuracy of the fingerprint identification area, and then reduces the brightness of the non-fingerprint identification area, without separately controlling the fingerprint identification area. Brightness, during this process, non-fingerprint recognition areas will appear flickering or sudden changes in brightness. In order to solve the above problems, the inventor found that by independently controlling the gray levels of all pixel units in the fingerprint identification area, reducing the correlation with the control of the gray levels of all pixel units in the non-fingerprint identification ar...

Abstract

The present invention provides a display device, comprising: a screen body, including a first display area and a second display area; and a display driver chip electrically connected to the screen body, used to drive the screen body to display and emit light; wherein, The display driver chip includes: a first preset grayscale generating module, configured to generate a first preset grayscale voltage; a second grayscale generating module, configured to calculate the voltage of each pixel in the second display area according to image data the gray scale required by the unit, and generate a gray scale voltage interval including a plurality of gray scale voltages; the gray scale driving module is used to select the gray scale voltage required by each pixel unit in the second display area from the gray scale voltage interval a gray-scale voltage corresponding to the gray-scale; and a first control module, configured to control the gray-scale driving module to distribute the first preset gray-scale voltage to all pixel units in the first display area. By independently controlling the gray scale of the first display area, flickering or abrupt brightness changes in the second display area are avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method. Background technique [0002] With the continuous development of display technology, optical screen fingerprint recognition technology has attracted much attention. In the existing display device, during the optical fingerprint wake-up period, the fingerprint recognition area of ​​the screen needs to be turned on with the highest brightness to ensure the accuracy of fingerprint recognition. However, non-fingerprint recognition areas are prone to flickering or sudden changes in brightness, which affects user experience. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a display device and a display method to solve the problem of flickering or sudden change in brightness of non-fingerprint identification areas in the prior art. [0004] One aspect of the present invention provide...
