Abstract

A screen uniformity calibration method and a terminal device are disclosed in the embodiment of the present invention, wherein the screen of the terminal device applied to the terminal device comprises N regions, a photosensitive sensor is correspondingly arranged under each area, wherein, the method comprises the following steps of: displaying a color temperature test image when the terminal device is in a dark environment, wherein the color temperature test image is a solid color image whose brightness is higher than a preset value; collecting display parameters of each area of the screen, wherein the display parameters are color temperature or screen brightness; adjusting the display parameters of each of the regions with reference to preset target display parameters; where N is an integer greater than 1. The screen uniformity calibration method provided by the invention can quickly and effectively calibrate the screen uniformity of the terminal equipment.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for calibrating screen uniformity and a terminal device. Background technique [0002] With the gradual popularization of terminal equipment color screens, the material of terminal equipment screens is becoming more and more important. The types of screens of terminal devices generally include TFT (Thin Film Transistor, Thin Film Field Effect Transistor), TFD (Thin Film Diode, Thin Film Diode) and OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) and so on. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the layers of the picture will be richer. [0003] At present, due to factors such as the voltage drop of the screen trace impedance and manufacturing, the screen has poor display uniformity. For example, the upper half of the screen is bright and the lower half...
