Abstract

The invention discloses a self-capacitance touch display panel and a display device. The self-capacitance touch display panel comprises a display area and frame areas, and the frame areas are arranged on the two sides of the column direction of the display area. The display panel further comprises a plurality of touch sensing units which are arranged in the display area at intervals in a row-column mode. a touch signal line, of which one end is connected to the touch sensing unit, and the other end is connected to the touch integrated circuit, wherein the touch signal lines comprise a plurality of first touch signal lines and a plurality of second touch signal lines, and the first touch signal lines are connected with the touch sensing units close to the frame area and extend to the frame area from the display area. The self-capacitance touch display panel and the display device have the beneficial effects that the touch signal lines on the edge of the display area extend into the frame area, so that the effective touch area of the display area close to the frame area is effectively increased, the touch performance of the display area close to the frame area is improved, and therefore, a problem that the touch performance of the display area close to the frame area is poor is solved.

Description

technical field [0001] The present application relates to the field of touch control, in particular to a self-capacitive touch display panel and a display device. Background technique [0002] Display devices mainly include liquid crystal display (LCD: liquid crystal display), plasma display panel (PDP: plasma display panel), organic electroluminescence (OLED: Organic light emitting diode), active matrix organic electroluminescence (AMOLED: active -matrix organic light emitting diode), which has broad application space in vehicle, mobile phone, tablet, computer and TV products. [0003] Generally speaking, the touch function has become one of the standard configurations of most display devices. Capacitive touch panels are widely used. The basic principle is to use tools such as fingers or stylus to generate capacitance with the touch screen, and use touch The electrical signal formed by the front and rear capacitance changes is used to confirm whether the panel is touched a...
