Abstract

The embodiment of the present invention discloses a wake-up method and device based on a self-capacitance touch screen, which relates to the technical field of touch screens, and the main purpose is to solve the problem of waking up the self-capacity touch screen from standby to wake-up. The problem of high power consumption of screen scanning. The main technical solution of the embodiment of the present invention is to detect whether there is a touch signal in a preset area in the self-capacitive touch screen, and the preset area is a wake-up activation area that receives a touch signal for waking up the self-capacitive touch screen; if so, Then wake up the self-capacitance touch screen to the working state; if not, then control the self-capacity touch screen to a preset standby state, and the preset standby state is in the self-capacity touch screen except the preset area All other areas are closed. The embodiment of the present 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...
