Problems solved by technology

[0006] However, both ITO and IZO films have non-negligible resistance
When the indium tin oxide film or indium zinc oxide film is used to form a capacitive sensor, a resistance-capacitor filtering effect will be generated, which will cause the capacitive sensor far away from the control circuit to be unable to accurately detect capacitance changes, resulting in Capacitive touchpad operation error
Especially when the capacitive sensor is placed under a thicker interface, the capacitive sensor is even more unable to detect changes in capacitance
[0007] This shows that the above-mentioned existing touch panel obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Abstract

The present invention relates to a touch control panel which comprises a control circuit and a touch screen connected with the control circuit. The control circuit is used for generating an X-Y coordinate signal. The touch screen comprises a transparent substrate and a transparent conductive film installed on the transparent substrate. The transparent conductive film comprises a plurality of capacitance inducers which are arranged along X-axis direction and Y-axis direction. These capacitance inducers are patterned to the pattern which has equalizing resistance capacitance distribution. The touch control panel according to the invention can accurately detect the position of the contact on the touch screen.

Description

technical field [0001] The invention relates to a touch panel for a display device, in particular to a capacitive touch panel for a display device that can accurately detect the position of a touch point on a touch screen. Background technique [0002] The touch panel can be used as an interface tool for operating an electronic device through a display screen. For example, a user can input desired information on a display device that is displaying an image and combined with a touch panel. Since the user can input information into the electronic device through the display screen, the use of the touch panel can reduce or omit the user's need for other types of input devices (eg, keyboard, mouse, remote controller, etc.). Currently, the touch panel has been widely integrated into the display screen of the flat panel display device, such as liquid crystal display device, plasma (ie, plasma) display device, organic electroluminescence (LE, electroluminescence) device and cathode...
