Problems solved by technology

[0003] However, the capacitive sensing touch panel can only determine the coordinates of the finger according to the capacitance change, and cannot sense the pressure
Therefore, the traditional touch panel must rely on the finger to press twice at the same position when inputting the system software execution command (Enter), and software assistance is needed to judge, but if the position is shifted after being pressed twice, or the time interval is too long or Too short, it is not easy to judge the execution command requested by this finger

Embodiment Construction

[0041] The present invention provides a touch panel with positioning and pressure sensing, please refer to Figure 2A , which shows a schematic cross-sectional view of a touch panel according to an embodiment of the present invention. Firstly, a first substrate 100 is provided, such as a glass substrate, having an inner surface 100a and an outer surface 100b, a color filter layer 106 is disposed on the inner surface 100a, and a positioning sensing structure 102 is disposed on the outer surface 100b. The position sensing structure 102 can sense the position where the panel is touched, which can be as figure 1 The shown capacitive sensing element determines the touch position by sensing the capacitance generated by the finger touching the panel. In addition, in another embodiment, the positioning sensing structure 102 can also be a light sensing element (not shown), and two groups of light emitters and light receivers are respectively arranged in the X and Y directions, and are...

Abstract

The invention discloses a touch panel and a touch display device. The touch panel comprises a first substrate with an internal surface and an external surface, a localization sensing structure arranged on the internal surface or the external surface of the first substrate, a second substrate arranged opposite to the first substrate and facing the internal surface of the first substrate, a plurality of press sensing structures arranged between the first substrate and the second substrate and a signal connecting wire in series connection with all press sensing structures. The touch display device comprises the touch panel.

Description

technical field [0001] The invention relates to a touch display device including a touch panel, in particular to a touch panel with a positioning and pressing sensing structure. Background technique [0002] The traditional touch panel is generally a capacitive sensing touch panel. The capacitive sensing touch panel uses the capacitance between the finger and the sensing electrode to determine the position of the finger. see figure 1 , which shows a schematic plan view of sensing electrodes of a conventional capacitive sensing touch panel, where the sensing electrodes include a plurality of X-axis sensing electrodes 10 and Y-axis sensing electrodes 20 . When the signal scans to a certain X-axis sensing electrode, the remaining X-axis sensing electrodes and Y-axis sensing electrodes are grounded, and the scanning X-axis sensing electrode and the rest of the grounded Y-axis sensing electrodes will generate capacitance Cx-y, But when there is a finger touching the X-axis sens...
