Abstract

The present invention relates to a touch sensing device and a touch sensing method. The touch sensing device according to one aspect of the present disclosure includes a touch coordinate calculation unit configured to calculate a touch coordinate corresponding to the touch label on the basis of touch intensities of touch electrodes included in the touch label; a representative value calculation unit configured to calculate a representative value of the touch label by correcting the maximum touch intensity value of the touch label on the basis of a coordinate of a target touch electrode and the touch coordinate when the touch input corresponding to the touch coordinate is detected in the edge region of the target touch electrode among the touch electrodes; and a touch coordinate transmission unit configured to determine the touch input as a normal touch when the representative value is greater than or equal to a first threshold and transmit the touch coordinate to a host system.

Description

technical field [0001] This specification relates to a touch sensing device. Background technique [0002] With the development toward an information society, various demands on display devices for displaying images are increasing. Recently, various types of display devices such as liquid crystal display (LCD) devices or organic light emitting diode (OLED) display devices are being used. [0003] In recent years, a display device having a touch screen panel capable of detecting a touch input of a user's finger, stylus, etc. has been widely used in order to depart from conventional input methods using buttons, keyboards, mice, and the like. A display device having such a touch screen panel includes a touch sensing device for accurately detecting the presence or absence of a touch and touch coordinates (touch position). [0004] The touch sensing device assigns identification information to touch electrodes on the touch screen panel whose touch intensity is calculated to be ...
