Problems solved by technology
[0005] Since the touch sensing layer—the ITO layer is prefabricated on one side of the CF substrate, and then CF is fabricated on the other side of the CF substrate, when performing CF fabrication, the CF substrate must be turned over so that the side where the ITO layer is located faces The ITO layer is in direct contact with the machine, and it is easy to scratch the ITO layer, which will cause the panel to be reworked or scrapped

Abstract
The invention provides a manufacturing method of a touch control display panel. The method includes the steps that a display panel semi-finished product is provided, the display panel semi-finished product comprises an array substrate, a color filter substrate and a liquid crystal layer, the liquid crystal layer is located between the array substrate and the color filter substrate, and according to the display panel semi-finished product, assembling of the array substrate, the color filter substrate and the liquid crystal layer is completed; a photoresistance pattern complementary to a touch control sensing layer pattern is formed on the surface of the side, away from the liquid crystal layer, of the color filter substrate; an ITO membrane is formed on the photoresistance pattern and the color filter substrate which is not covered with the photoresistance pattern; the ITO membrane is etched selectively, the ITO membrane above the photoresistance pattern is etched and removed, the photoresistance pattern is exposed, and the ITO membrane above the color filter substrate which is not covered with the photoresistance pattern is maintained; the photoresistance pattern is stripped off, and the touch control sensing layer pattern is formed.
Description
technical field [0001] The present invention relates to the technical field of touch display, in particular to a method for manufacturing a touch display panel. Background technique [0002] With the development of the information age and the acceleration of the pace of life, touch technology has gradually replaced the traditional mouse and keyboard due to its humanized design and simple and fast input, and is widely used in various electronic products. Among them, the capacitive touch screen is widely used due to its advantages of fast response, high sensitivity, good reliability and high durability. Capacitive touch screen mainly includes protective glass (CoverLens) and touch sensing layer (TouchSensor). The sensing principle is to apply voltage to the four corners of the screen sensing area and form a fixed electric field. Capacitance changes between the electrodes can cause the electric field to induce a current, measured by the controller, and the contact position can...
