Abstract

The technical field of touch panel is related to. A touch panel provided herein includes a touch area and a peripheral area. A first driving circuit and a GOA circuit are provided in the peripheral area. The first driving circuit and the GOA circuit include same stage transmission units, and share a same driving signal. The first driving circuit is sandwiched in the GOA circuit, and thus a layout space of the first driving circuit can be saved, which can facilitate realization of narrow frame design. Sensor pads in the touch area are arranged in a rectangular array, and a first sensor pad and a last sensor pad of each row of sensor pads are connected with the first driving circuit respectively. Two adjacent sensor pads are connected by a first connecting line or a second connecting line. A display device including the touch panel is further provided.

Description

technical field [0001] The invention relates to the field of built-in touch panels, in particular to a touch panel and a display device. Background technique [0002] The built-in touch panel is a panel that integrates TP (Touch Panel, touch panel) functions into the thin film transistor liquid crystal display (TFT-LCD) array process, which can realize the thinning and thinning of the panel and even the whole machine. The mutual capacity built-in panel is a kind of built-in touch panel, which includes a sensor pad (Sensor Pad), a first connection line and a second connection line. Commonly used mutual capacitive built-in touch panels, such as figure 1 As shown, a sensing pad 10 is arranged between the first edge 13 and the second edge 14, and every two adjacent sensing pads are connected by the first connecting line 11 and the second connecting line 12, meanwhile, at the first edge 13 A GOA circuit 17 and a first signal line 18 are arranged between the first frame 15 and a...
