Abstract

An embodiment of the invention discloses a wake-up method and device based on a self-capacitive touch screen, and relates to the technical field of touch screens. A main objective is to solve the problem of large power consumption for screen scanning during the process of the screen from a standby state to a wake-up state when the existing self-capacitive touch screen is waken up. The main technical solution of the embodiment of the invention is: detecting whether there is a touch signal in a preset area in the self-capacitive touch screen, wherein the preset area is a wake-up activation areafor receiving a touch signal for waking up the self-capacitive touch screen; if so, waking up the self-capacitive touch screen to a working state; if not, controlling the self-capacitive touch screento a preset standby state, wherein the preset standby state is a state in which other areas other than the preset area in the self-capacitive touch screen are all closed. The embodiment of the invention is mainly used in the wake-up process of the self-capacitive touch screen.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch screens, in particular to a method and device for waking up based on a self-capacitive touch screen. Background technique [0002] With the continuous advancement of technology, smart devices have gradually become popular. Usually, smart devices are equipped with touch screens, such as mobile phones, tablet computers and other devices. During the use of smart devices, since the power of the built-in battery of the device is limited, the power consumption of the device will directly affect the use time of the device after a single charge, thereby affecting the actual user experience of the user. During the use of the device, since the touch screen is a device that consumes a large amount of energy, its power consumption has a great impact on the use time of the device. [0003] In smart devices, self-capacitance touch screens are generally provided. This type of touch screen i...
