摘要： A display device includes a driver circuit on a display panel, a conductive frame that is disposed behind the display panel and supplies a frame ground, a control printed board disposed behind the conductive frame, and a conductive shield cover covering at least a part of the back face of the control printed board. The control printed board includes a front ground pad and a backside ground pad. The front ground pad is electrically connected to the back face of the conductive frame. The backside ground pad is electrically connected to the conductive shield cover. A part of an end of the conductive shield cover is electrically connected to the partial region.

摘要： A touch panel includes arranged touch electrodes, and a driver IC connected to each of the touch electrodes. The plurality of touch electrodes is grouped into a plurality of groups such that electrodes belonging to different groups are included in a range smaller than an object to be detected, such as a finger. The driver IC alternately or sequentially applies a driving voltage to the touch electrodes of the plurality of groups, detects a capacitance of each of the sensor electrodes, and detects, based on the detected capacitance, whether there is a touch.
