Embodiment Construction

[0050] In order to improve touch sensitivity, an embodiment of the present invention provides a touch screen, including a base substrate, a plurality of first touch electrodes extending along the row direction and second touch electrodes extending along the column direction on the base substrate. An electrode, and a medium layer between the first touch electrode and the second touch electrode; the thickness of the medium layer in the overlapping area of ​​the first touch electrode and the second touch electrode is greater than the thickness of other areas.

[0051] In the embodiment of the present invention, in the dielectric layer between the two layers of touch electrodes, the thickness of the area where the two layers of touch electrodes overlap is greater than the thickness of other areas, such as the edge, and correspondingly, the generated capacitance is Smaller than the capacitance at the edge, it reduces the impact on the touch effect and improves the touch sensitivity....

Abstract

Embodiments of the invention disclose a touch screen, a display apparatus and a manufacturing method for the touch screen. The touch screen comprises a substrate, a plurality of first touch electrodes extending in a row direction and arranged on the substrate, a plurality of second touch electrodes extending in a column direction and arranged on the substrate, and medium layers between the first touch electrodes and the second touch electrodes, wherein the thickness of each medium layer in an overlapping area of each first touch electrode and each second touch electrode is greater than the thickness of the medium layer in other area. According to the scheme, in the medium layer between the two layers of touch electrodes, the thickness of the medium layer in the overlapping area of the two layers of touch electrodes is greater than the thickness of the medium layer in other area, such as the edge, correspondingly, the generated capacitance is smaller than the capacitance at the edge, so that the influence on the touch effect is reduced and the touch sensitivity is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch screen, a display device and a manufacturing method of the touch screen. Background technique [0002] In the current touch screen, touch sensitivity is a very important performance index, and there are many factors that affect touch sensitivity. For example, in an existing touch screen, two layers of touch electrodes are made, and the touch There is a dielectric layer between the electrodes. The capacitance at the overlap of the two layers of touch electrodes and the capacitance at the edge will affect the touch effect, especially the large capacitance at the overlap of the two layers of touch electrodes will reduce the touch. Sensitivity of the touch control; where the touch electrode overlaps another touch electrode is called the edge; for another example, the distance between the touch electrode and the finger will also reduce the touch sensitivity of the touch scree...
