Array substrate and manufacturing method thereof

Abstract

The invention provides an array substrate and manufacturing method thereof. The array substrate includes a gate line and a data line which are crisscrossed, a touch control wire, a plurality of pixel regions defined by intersection of the gate line and the data line, a TFT switch at the intersection of the gate line and the data line, a gate insulation layer located on the gate line, an oxide semiconductor located on the gate insulation layer, a first insulation layer that covers the oxide semiconductor and the data line, a third insulation layer that covers the first insulation layer, pixel electrodes located on the third insulation layer and located in the pixel regions, a pad layer located under the touch control wire, a second insulation layer that covers the touch control wire and pixel electrodes, and a plurality of common electrodes located on the second insulation layer. The array substrate uses a gray scale mask plate, through a reduced number of mask processes, the array substrate having a touch control function is prepared, and compared with a conventional design, the array substrate preparation process is obviously simplified, the yield of array substrates is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a touch screen, in particular to an array substrate and a manufacturing method thereof. Background technique [0002] Since the iPhone 4 adopts a capacitive touch screen, the public's requirements for the touch screen experience have also increased, and the touch screen has become the mainstream in the display field. [0003] Currently, the most widely used touch panels are Add on Touch Panels that are mounted outside the display screen and In cell Touch Panels that are embedded in the display screen. The built-in touch screen integrates the touch function inside the LCD, which greatly meets the needs of consumers for thinner displays, and is also synonymous with high-end products. [0004] However, for the design of the existing embedded touch screen array substrate, the structure of each film layer and the process flow are relatively complicated, and the number of masks is large, which leads to high preparation costs and lim...
