Problems solved by technology

However, when the transparent cover 103 is a curved surface or a spherically curved substrate, since its overall thickness will no longer be uniform, the vertical distance between each sensing unit and the touch surface of the transparent cover 103 will be different. The capacitance value of a sensing unit is also different, which will cause interpretation errors in touch sensing and affect the quality of touch sensing

Embodiment Construction

[0036] The following is a detailed description of preferred embodiments of the present invention with the accompanying drawings. The following description and drawings use the same reference numerals to indicate the same or similar elements, and repeated descriptions of the same or similar elements are omitted.

[0037] The traditional way of disposing the touch sensing layer is to adopt the sensing units with the same area, and distribute and arrange them on the transparent cover plate or the glass substrate with the same pitch. When the transparent cover is formed of a glass with different thickness (that is, the thickness is not uniform), because the vertical distance between each sensing unit and the upper surface of the transparent cover is different, different capacitance values ​​will be formed, and in The touch sensing will cause interpretation errors and affect the quality of touch sensing. Therefore, the present invention corrects the area of ​​each sensing unit and ...

Abstract

A touch panel comprises a substrate, a touch sensing layer and a transparent cover plate. The touch sensing layer is disposed on the substrate. The transparent cover plate is of different thicknesses and is disposed on the touch sensing layer. The touch sensing layer comprises a plurality of touch units; each touch unit corresponds to single thickness of the transparent cover plate; according to the single thickness of the transparent cover plate, area of each touch unit and spacing between the touch unit and the adjacent one are set.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch sensing layer structure of the touch panel. Background technique [0002] figure 1 Shown is a schematic cross-sectional view of a capacitive touch display panel. Generally speaking, the touch display panel 100 includes a display panel (display panel) 101, a touch panel 102 disposed on the display panel, wherein the touch panel 102 includes a substrate 105, a transparent cover 103 and a touch panel. The sensing layer 104 is formed on the substrate 105 , wherein the transparent cover 103 is used to protect the touch sensing layer 104 and the display panel 101 thereunder. like figure 1 The touch panel 102 shown is a double glass touch panel structure (G / G type). In another One Glass Solution (OGS) touch panel structure, the touch sensing layer 104 is directly disposed on the transparent cover 103 without the substrate 105 . [0003] figure 2 Shown is a known capacitive tou...
