Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0024] The current self-capacitive oncell touch structure is to set two layers of metal layers on the packaging layer, and the two layers of metal layers are respectively made to form the touch electrode layer and the touch lead layer. The units all lead to the touch lead layer, so there are many touch lead layers. For example, taking an 8-inch screen as an example, the touch unit is 4.2mm, and the touch unit requires at least more than 1,000 touch lead layers. The touch lead layer and the touch elec...

Abstract

The embodiment of the invention provides a touch control substrate, a preparation method thereof and a display device. The touch control substrate comprises a substrate, a touch control lead layer arranged on the substrate, a packaging layer arranged on the touch control lead layer and a touch control electrode layer arranged on the packaging layer. The packaging layer is internally provided witha first opening hole communicated with the touch control lead layer, the touch control electrode layer is connected with the touch control lead layer through the first opening hole, the distance between the touch electrode layer and the touch lead layer can be increased, and parasitic capacitance generated between the touch control electrode layer and the touch control lead layer is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch substrate, a preparation method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is the development trend of future display products, with a series of advantages such as wide viewing angle, fast response speed, high brightness, high contrast, bright colors, light weight, thin thickness, and low power consumption. Currently, organic light emitting diode display devices have begun to be applied to mobile phone screens. [0003] With the emergence and continuous development of OLED display technology, flexible display has become the trend of future display development. Bending and rollable flexible screens are widely used in mobile phones and tablets, which requires the touch layer to also need bending performance. Therefore, the current AMOLED flexible screen has changed from a plug-in mutual capacity structure to an...
