Embodiment Construction

[0051] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] An embodiment of the present invention provides a wake-up method based on a mutual capacitive touch screen, such as figure 1 As shown, the method includes:

[0053] 101. Detect whether a touch signal exists in a preset area in a mutual capacitive touch screen.

[0054] Wherein, the preset area includes at least one wake-up point, and the wake-up point is a position for receiving a touch signal for waking up the mutual capacitive touch s...

Abstract

The embodiment of the present invention discloses a wake-up method and device based on a mutual-capacitance touch screen, which relates to the technical field of touch screens, and the main purpose is to solve the problem of detecting touch while the screen is waiting for wake-up when the existing mutual-capacity touch screen is woken up. The problem of high power consumption during the signal. The main technical solution of the embodiment of the present invention is: detecting whether there is a touch signal in the preset area in the mutual capacitive touch screen, the preset area contains at least one wake-up point, and the wake-up point is used to The position of the touch signal of the capacitive touch screen; if so, wake up the mutual capacitive touch screen to the working state; if not, then control the mutual capacitive touch screen to a preset standby state, and the preset standby state is the interactive Other areas in the capacitive touch screen except the preset area are in a closed state. The embodiment of the present invention is mainly used in the wake-up process of the mutual 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 mutual 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] Since the mutual capacitive touch screen can support multi-point touch, this type of touch screen ...
