Problems solved by technology

In order to obtain higher touch accuracy, it is necessary to reduce the line width of the touch scanning line and the touch sensing line, but this will cause the resistance value of the touch scanning line and the touch sensing line to increase, resulting in delay to the signal; in order to reduce the resistance of the touch scanning line and the touch sensing line, it is particularly important to select low-resistance materials

Abstract

Embodiments of the invention provide a touch display panel and a manufacturing method thereof, relate to the technical field of touch displaying and aim to reduce resistance of touch electrodes, improve signal lag and increase touch precision accordingly. The touch display panel comprises an array substrate and a color film substrate abutted to each other. The touch display panel further comprises a group of parallel first electrode lines arranged on the array substrate or the color film substrate, and a group of parallel second electrodes; the second electrode lines arranged on the array substrate or the color film substrate intersect with the first electrode lines for arraignment; the first electrode lines are non-electrically connected with the second electrode lines. The first electrode lines and / or the second electrode lines correspond to a black array of the color film substrate in position; the first electrode lines and / or the second electrode lines corresponding to the black array in position are metal electrode lines. The touch display panel and the manufacturing method thereof are applicable to manufacturing of touch display devices.

Description

Technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a preparation method thereof. Background technique [0002] With the continuous development of display technology, the research on the integration of touch panel functions and liquid crystal display panels has become increasingly popular. [0003] At present, the integrated technology research and development route of the in-cell touch screen mainly includes on-cell touch and in-cell touch. The difference between the two is: on-cell touch is a touch technology that embeds the touch panel function between the color film substrate and the polarizing plate. Specifically, the touch sensor component layer in the touch panel is made on On the base substrate and bonded with the color filter, so as to be embedded in the liquid crystal pixel; in-cell touch is a touch technology that embeds the touch panel function into the liquid crystal pixel, specifical...
