Problems solved by technology
[0003] However, the direct operation of the touch screen will have certain limitations. For example, if the test of the touch screen needs to be performed manually, it will be inefficient and waste manpower; After all, the feedback of the touch screen to human fingers is not as good as that of physical buttons. Therefore, there are currently gamepads for smart mobile terminal devices. The smart mobile terminal and the gamepad are connected wirelessly (such as Bluetooth connection, etc.) Mini USB interface connection, etc.) to transmit signals, wireless connections often have delays, wired connections require cables, and the corresponding gamepads need to be equipped with corresponding communication modules to communicate, which increases the limitations of the design

The invention discloses a touch device and a touch method applied to a capacitive touch screen. According to the method, through prestored excitation signal data of each pixel point on each first coordinate axis, when simulated touch operation needs to be performed, excitation signal data of a target touch point at a to-be-touched position is acquired from the excitation signal data and generated,and a simulated touch signal is generated and output to a signal receiving electrode corresponding to the target touch point to complete simulated touch operation. Through the touch device and the touch method, existing technical problems are solved, design is easy, and the structure is simple; and meanwhile, only a signal output component is needed, a signal collection component is not needed tocollect an excitation signal on a signal sending electrode, and therefore cost is lowered.
Description
technical field [0001] The invention relates to the field of touch technology, in particular to a touch device and a touch method applied to a capacitive touch screen. Background technique [0002] At present, smart mobile terminals such as smart phones or tablet computers are very popular. These smart devices generally use touch screens, such as capacitive touch screens or resistive touch screens, which can realize WYSIWYG operations and are more intuitive. [0003] However, the direct operation of the touch screen will have certain limitations. For example, if the test of the touch screen needs to be performed manually, it will be inefficient and waste manpower; After all, the feedback of the touch screen to human fingers is not as good as that of physical buttons. Therefore, there are currently gamepads for smart mobile terminal devices. The smart mobile terminal and the gamepad are connected wirelessly (such as Bluetooth connection, etc.) Mini USB interface connection, ...
