Problems solved by technology

However, since ITO has a certain resistance value, when the size of the touch display panel is larger or the width of the driving electrode and the sensing electrode of the sensing circuit is smaller, the sensing circuit will be limited by the resistance value of ITO The obvious resistance-capacitance load effect makes the sensitivity of the sensing line uneven, and the signal size driving the sensing line needs to be increased, thereby increasing the power loss of the touch display panel.

Abstract

The invention discloses an embedded touch display panel, which includes a substrate and a sensing circuit. Scanning lines and data lines are defined on the substrate, and the sensing lines are set corresponding to the scanning lines and data lines, wherein the sensing lines include multiple first electrode series, multiple grid electrode blocks, multiple electrode line segments, and multiple Transparent bridging electrodes. Each first electrode series includes a plurality of main sensing bars, and the main sensing bars are arranged corresponding to the scanning lines. The transparent bridging electrodes span each main sensing strip respectively, and the transparent bridging electrodes connect any two adjacent electrode line segments and any two adjacent grid electrode blocks and each electrode line segment to form a plurality of second electrode series .

Description

technical field [0001] The invention relates to an in-cell touch display panel, in particular to an in-cell touch display panel in which sensing circuits are integrated in an array substrate. Background technique [0002] With the rapid development of science and technology, the touch panel has been widely used in the external input interface of the instrument due to its human-computer interaction characteristics. In recent years, with the wide application of consumer electronics products, there are more and more application products that combine the touch function with the display panel to form a touch display panel, such as: mobile phone (mobile phone), satellite navigation system ( GPS navigator system), tablet PC (tablet PC), personal digital assistant (PDA) and notebook computer (laptop PC), etc. [0003] Currently, in the traditional touch display panel, the driving electrodes and sensing electrodes of the sensing circuit are formed of transparent indium tin oxide to ...
