Problems solved by technology

[0004] In the prior art liquid crystal cell products, In-Cell refers to the method of embedding the touch panel function into the liquid crystal pixel, that is, embedding the touch sensor function inside the display screen, making the touch panel relatively light and thin, and adopting a square touch sensor design, Due to the different resistance-capacitance delays of adjacent touch sensors, the large resistance-capacitance delay on the macroscopic scale will cause vertical stripe cracks between the sensors
[0005] To sum up, the display panels in the prior art are prone to resistance and capacitance delays and cracks.

Abstract

The invention provides a touch panel which comprises a substrate and a touch layer located on the substrate, the touch layer comprises a plurality of touch units arranged at intervals, an area betweenevery two adjacent touch units forms a lead area, and the lead areas are filled with lead materials;the edge of each touch unit is engaged with the edge of at least one adjacent touch unit, the touchpanel has the advantages that the graph of the touch unit inside the touch panel is made into a matched shape, the resistance-capacitance delay effect of the touch panel is reduced, and then the situation that the touch panel cracks is relieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch panel and a preparation method thereof. Background technique [0002] With the development of large-size display applications, there are more and more demands for human-computer interaction, and touch applications have become an important medium in human-computer interaction. [0003] According to the position where the touch circuit is embedded in the liquid crystal display panel, the embedded touch panel can be divided into a touch circuit on the liquid crystal cell (On Cell) type and a touch circuit in the liquid crystal cell (In Cell) type. [0004] In the prior art liquid crystal cell products, In-Cell refers to the method of embedding the touch panel function into the liquid crystal pixel, that is, embedding the touch sensor function inside the display screen, making the touch panel relatively light and thin, and adopting a square touch sensor design, Since adjace...
