Problems solved by technology

However, under the built-in design, the relevant circuits of the sensing element need to be fabricated inside the display panel, which will increase the manufacturing process of the display panel and affect the electrical properties of the sensing element
For example, the coupling between the sensing element and other components or circuits will increase the load on the sensing element, which will affect the sensing ability and sensing quality of the sensing element

Abstract

The invention provides a touch display panel and a pixel structure. A touch display panel includes a substrate, a sensing electrode layer, a metal layer and an active unit layer. The sensing electrode layer is disposed on the substrate and includes a plurality of sensing electrodes separated from one another and arranged in an array. The metal layer is disposed on the substrate and includes a plurality of signal lines. One signal line is used for transmitting a signal between one sensing electrode and a driving circuit. The active unit layer is disposed on the substrate and is located between the sensing electrode layer and the metal layer. The touch display panel can reduce stray capacitance born by a sensing electrode.

Description

technical field [0001] The present invention relates to a display device, in particular to a touch display panel and a pixel structure. Background technique [0002] In recent years, various electronic products are increasingly integrating touch-sensitive elements into the display panel, so as to omit the space required for the keyboard or control keys, and to expand the configurable area of ​​the screen. Therefore, the application of the touch display panel is becoming more and more popular and extensive. Generally speaking, the touch display panel can be built into the display panel with sensing elements, such as sensing electrodes, or externally attached to the display panel, such as a flat touch panel. [0003] The touch sensing element built into the display panel can reduce the thickness of the touch display panel, and also simplify the assembly of electronic products. However, under the built-in design, the relevant circuits of the sensing element need to be fabrica...
