Abstract

Embodiments of the invention relate to the technical field of infrared touch control devices, and particularly relate to a display screen brightness adjustment method and device. The method comprises: when there is no user touch control action, periodical sampling of an infrared receiving tube in an infrared touch control frame is performed; whether the difference values between infrared signal parameter values of N consecutive samplings and a reference parameter value are all greater than an abrupt change threshold is determined, wherein the N is an integer not less than 2; when the difference values between the infrared signal parameter values of N consecutive samplings and the reference parameter value are all greater than the abrupt change threshold, a display brightness adjustment command is generated. According to the technical scheme, the method and the device can adjust the brightness of high-sensitivity display screen without adding extra light sensing elements.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of infrared touch devices, and in particular to a method and device for adjusting brightness of a display screen. Background technique [0002] The display effect of the display screen of the terminal device is closely related to the light intensity of the environment where the terminal device is located. In order to make the terminal device have a better display effect, the brightness of the display screen can be adjusted according to the light intensity of the surrounding environment. [0003] Currently, there are two ways to adjust the brightness of the display screen. One is that the user manually adjusts the brightness of the display screen of the terminal device according to personal experience; The signal collected by the photosensitive device determines the change of the light intensity in the environment, and automatically adjusts the brightness of the display screen of the te...
