Abstract

The invention discloses a capacitance type touch display panel comprising a display panel, a touch sensing unit and a plurality of floating grid static protective elements, wherein the display panel comprises a sensing area; the touch sensing unit is arranged in the sensing area of the display panel and comprises a plurality of first sensing serials and a plurality of second sensing serials; the plurality of first sensing serials are arranged along a first direction and each first sensing serial comprises a plurality of first sensing pads which are mutually and electrically connected; the plurality of second sensing serials are arranged along a second direction and each second sensing serial comprises a plurality of second sensing pads which are mutually and electrically connected; the plurality of floating grid static protective elements are arranged in the sensing area of the display panel; and each floating grid static protective element is arranged among two first sensing pads which are adjacent but not electrically connected and two second sensing pads which are adjacent but not electrically connected. The capacitance type touch device is provided with the floating grid static protective elements in the sensing area, thereby effectively improving the static protecting capability of the capacitance type touch device.

Description

technical field [0001] The present invention relates to a capacitive touch display panel and a capacitive touch substrate, in particular to a capacitive touch display panel and a capacitive touch substrate in which a floating gate electrostatic protection element is arranged in a sensing area . Background technique [0002] In today's market of various consumer electronic products, portable electronic products such as mobile phones, satellite navigation systems (GPS) and digital audio-visual players have widely used touch panels as man-machine Data communication interface. Since the current design of consumer electronic products emphasizes thinness and compactness, traditional input devices such as buttons and mice are expected to save space in product design, so touch input is adopted. In addition, with the introduction of touch operating system software, it is expected to drive another wave of demand for touch panels. [0003] Today's touch panels are mainly capacitive ...
