Problems solved by technology

[0005] In addition, when the driving electrodes and the receiving electrodes are implemented on the same layer, compared with touching while holding a device such as a smartphone equipped with a touch sensor board, touching the above-mentioned device while not holding the smartphone When touching the sensor board, there is a problem that the output touch signal changes due to LGM (low ground mass)
In particular, when the user does not hold the above-mentioned device with his hand (hereinafter referred to as the floating state), there is a problem that the output touch signal is split to the left and right or up and down.
Due to the problem of left-right splitting or up-down splitting of the output touch signal in this way, the above-mentioned device mistakenly judges one touch input by the user as two or more multi-touches, which may cause unexpected malfunction of the above-mentioned device by the user.

Description

technical field [0001] The present invention relates to a touch sensor board, and more particularly, to a touch sensor board capable of improving splitting of an output touch signal when a device having the touch sensor board is touched with one finger without holding it by hand. Background technique [0002] Various input devices are utilized in order to operate computing systems. For example, input devices such as buttons, keys, joysticks, and touch screens are used. Due to the simplicity and ease of operation of touch screens, the utilization rate of touch screens in operating computing systems has increased. [0003] The touch screen may constitute a touch surface of a touch input device including a touch sensor panel, which may be a transparent plate having a touch-sensitive surface. The touch sensor pad is attached to the front of the display, and the touch-sensitive surface covers the viewable side of the display. The user can operate the computing system simply by...
