Abstract

The invention relates to a display screen correction method and device, electronic equipment and a storage medium, the correction method is applied to terminal equipment with a display screen and a fingerprint identifier arranged in the display screen, and the correction method comprises the following steps: controlling the display screen to send a first optical signal; a reflection signal collected by the fingerprint identifier is obtained, the reflection signal is an optical signal obtained after the first optical signal is reflected by a jig, and the jig is arranged outside the display screen in advance; and adjusting the intensity of the first optical signal according to the reflected signal and a reference signal, so that the intensity of the reflected signal is the same as that of the reference signal. According to the technical scheme, the fingerprint identifier is used for collecting the reflection signal, so that a light intensity adjustment scheme with a negative feedback mechanism can be formed, namely, the light intensity of the display screen can be adjusted in a closed loop mode until the intensity requirement of the reference signal is met, the accuracy of light intensity adjustment of the display screen is improved, and the problem of inaccurate adjustment caused by an open-circuit adjustment mode is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of terminal equipment, and in particular, to a method, device, electronic device and storage medium for calibrating a display screen. Background technique [0002] With the advancement of science and technology, the functions of terminal equipment are more and more abundant, and the performance is more and more superior. Especially the display screen of terminal equipment has undergone several revolutionary progress and development in recent years, and the display performance has become more and more superior. The display screen of the terminal equipment needs to be optically calibrated both in the factory and in the process of use. The calibration in the related art is not accurate, and the display screen cannot maintain normal display brightness. SUMMARY OF THE INVENTION [0003] In order to overcome the problems existing in the related art, the embodiments of the present disclosure provide a c...
