Abstract

The present application provides a method for detecting the adjustment value of the brightness under the screen. The method for detecting the adjustment value of the brightness under the screen includes: calculating the brightness gain of the screen; calculating the real-time brightness of the screen according to the brightness gain and the real-time system brightness of the screen. Actual brightness; and calculate the off-screen light-sensing brightness adjustment value according to the real-time system brightness of the screen, the real-time actual brightness of the screen, and the maximum system brightness of the screen. In addition, the present application also provides an under-screen photosensitive brightness correction method, a photosensitive sensing device, and a terminal device. The technical solution of the present application can accurately acquire ambient light brightness.

Description

technical field [0001] The present application relates to the field of photosensitive technology, and in particular to a method for detecting an adjustment value of under-screen photosensitive brightness, a method for correcting under-screen photosensitive brightness, a photosensitive sensor device, and a terminal device. Background technique [0002] With the rapid development of electronic technology, electronic devices such as smart phones and tablet computers have become more and more popular. Among them, terminal devices such as smart phones and tablet computers all have display screens. [0003] Usually, an ambient light sensor is provided below the display screen. The ambient light sensor is used to detect the brightness of the external environment, so that the electronic device can control the brightness of the display screen according to the detected brightness of the external environment, so that the brightness of the display screen can adapt to the external envir...
