Problems solved by technology

A flat layer (PL) is usually formed on the active element (TFT) array substrate of the touch display device. When the third metal layer (M3) is used to realize the transmission of the touch signal and reduce the driving voltage, a large The area where the third metal layer is formed usually adopts the method of hollowing out the flat layer, so that no support pad (Bump) can be formed in the corresponding area
For the existing process, the thickness of the support pad is about 5500 angstroms, and the thickness of the third metal layer is about 3700 angstroms. The height difference of about 1800 angstroms, in turn, leads to the problem of uneven display of the touch display device

Abstract

The present invention provides a display device, comprising a first substrate, having a peripheral area and a display area adjacently arranged, and the display area is provided with a plurality of pixel units or a plurality of touch units; a first wiring structure, Arranged in the peripheral area, the first wiring structure is composed of a second metal layer and a third metal layer; a second wiring structure is arranged in the peripheral area, and the second wiring structure is composed of a second The metal layer is composed of; a support pad is arranged on the second wiring structure, and the position of the support pad is corresponding to the second wiring structure; and a second substrate is arranged opposite to the first substrate; Wherein, the first wiring structure and the second wiring structure are arranged alternately, the second metal layer is electrically connected to the plurality of pixel units or the plurality of touch control units, and the third metal layer respectively electrically connected to the plurality of pixel units or the plurality of touch units.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device with good display effect. Background technique [0002] With the development of technology, touch display devices are widely used in many electronic products, such as mobile phones, tablet computers, watches and so on. [0003] Existing touch display devices are usually manufactured using a low temperature polysilicon process (LTPS), and pixel units and control circuits are electrically connected through wiring (fan out). A flat layer (PL) is usually formed on the active element (TFT) array substrate of the touch display device. When the third metal layer (M3) is used to realize the transmission of the touch signal and reduce the driving voltage, a large The area where the third metal layer is formed usually adopts the method of hollowing out the flat layer, thus, no support pad (Bump) can be formed in the corresponding area. For the existing process, the thickne...
