Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] An embodiment of the present invention provides a method for waking up a touch terminal, such as figure 2 As shown, the method includes the following steps:

[0040] 201. In a standby state, the terminal performs unilateral scanning at a first scanning frequency to detect whether there is an effective touch.

[0041] When there is no user operation, the terminal is in the standby state. When the user needs to use the terminal, he can touch the terminal to ...

Abstract

The embodiment of the invention provides a method for rousing a touch terminal and the touch terminal, and relates to the technical field of touch. The power consumption of the terminal can be lowered, and the service life of the terminal can be prolonged. The method comprises the steps that when the terminal is in the standby state, single-side scanning is carried out through first scanning frequency, and whether effective touch exists or not is detected; if the effective touch exists, full-screen scanning is carried out through second scanning frequency, and the first scanning frequency is lower than the second scanning frequency.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a method for waking up a touch terminal and a touch terminal. Background technique [0002] As a human-computer interaction method, the touch screen is widely used in various electronic terminals, providing users with a WYSIWYG interaction method. Commonly used touch screens include resistive, capacitive, infrared, surface acoustic wave, etc. Among them, capacitive touch screens have the best touch effect; but the price and cost of capacitive touch screens are relatively high. The larger the size, the power consumption and cost problems are particularly prominent. For TVs, in order to seek alternatives to capacitive touch screens, it is common to develop infrared touch TVs using infrared touch detection devices combined with TVs. [0003] Such as figure 1 As shown, it is an infrared touch TV terminal in the prior art. The adjacent two sides of the touch screen of the te...
