Abstract

The invention provides a touch display device and drive method thereof. The device includes a first substrate, a sensing electrode layer positioned on the first substrate, a first passivation layer covering the sensing electrode layer, bridging patterns positioned on the first passivation layer, a pixel array positioned on the first passivation layer, a second substrate opposite to the first substrate, and a display media positioned between the first substrate and the second substrate; the sensing electrode layer includes first sensing electrode patterns and second sensing electrode patterns; each bridging pattern is electrically connected to two adjacent sensing electrode patterns and is across the corresponding first sensing electrode patterns; the pixel array includes scanning lines, data lines, active components which are electrically connected to the scanning lines and the data lines, and pixel electrodes; each active component includes a grid, a grid insulating layer, a drain and a source; each pixel electrode is electrically connected to the corresponding active component; the grid and the bridging patterns are formed by the same film layer. According to the invention, the manufacturing cost can be reduced, and the product performance is improved.

Description

technical field [0001] The present invention relates to a display device and a driving method, and in particular to a touch display device and a driving method. Background technique [0002] In recent years, with the rapid development of information technology, in order to achieve more convenience and humanization, many information products have changed from traditional input devices such as keyboards or mice to touch display devices as input devices. Generally speaking, based on the position of the touch sensing structure, the touch display device can be divided into out-cell, on-cell and in-cell. [0003] Taking an in-cell touch display device as an example, it includes a display panel and a touch sensing structure disposed in the display panel. Specifically, the display panel includes a first substrate, a second substrate opposite to the first substrate, a display medium between the first and second substrates, a pixel array between the first substrate and the display me...
