Problems solved by technology

[0005] However, since the sheet resistance of transparent conductive materials is much higher than metal materials such as gold, silver, and copper, when the size of the touch panel is large, the sheet resistance of the touch panel device will be greater than 1KΩ / square, and the board The capacitance value between the edge endpoints of the sheet 11 is greater than 400pF (pico-farad), which seriously affects the function of the control unit 14 to detect the coordinates of the touch point, so the size of the general capacitive touch panel device is limited to 7 inches or below 7 o'clock, cannot be applied to large display screens

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0028] See Figure 3, Figure 4 5, the first preferred embodiment of the touch panel device of the present invention is assembled on a general display screen 21, and a controller 22 detects the position of the contact point touched by the user, see Figure 4 , Figure 5 and Figure 6, the touch panel device comprises a horizontal transparent plate layer 3, a capacitive touch unit 4 located on the top surface of the plate layer 3 and made of transparent material, a capacitive touch unit 4 electrically connected to the capacitor The wire unit 6 of the type touch unit 4 and a protective film unit 7 covered on the capacitive touch unit 4 . In this embodiment, the touch panel device is installed on the display screen 21 (shown in FIG. 3 ) as an example for illustration.

[0029] In this embodiment, the plate layer 3 is a transparent substrate, and its composition materi...

Abstract

A touch control panel device comprises a horizontal transparent plate layer, a plurality of first and second electrodes arranged at the top of the plate layer in a matrix type alternatively, a plurality of first electric wires electrically connected with adjacent first electrodes, a plurality of second electric wires electrically connected with adjacent second electrodes, and a plurality of separate slices at the crossed parts of the first and the second electric wires. Each first or second electrode is made from metal material thinner than 250 angstroms or narrower than 200um, to reduce the plane resistance of the touch control panel device, improve conductivity and produce lager touch control panel. The metal lines are thinner than 250 angstroms or narrower than 200um, and therefore, users can not observe the first and the second electrodes on the plate layer to reduce plane resistance, improve the transparence of the whole touch control panel and support the use as a touch control medium of large screens.

Description

technical field [0001] The present invention relates to a touch panel device, in particular to a touch panel device installed on a display screen of an electronic device for a user to touch and operate the electronic device. Background technique [0002] FIG. 1 shows the structure of a general capacitive touch panel device at present. The capacitive touch panel device has a horizontal sheet layer 11 made of a transparent material, and a first electrode positioned on the top surface of the sheet layer 11. Unit 12, a second electrode unit 13 located on the bottom surface of the plate layer 11, a control unit 14, a second electrode unit 13 extending inward from the periphery of the top surface of the plate layer 11 and electrically connecting the first electrode unit 12 and the control unit A wire unit 15 , and a second wire unit 16 extending inward from the periphery of the bottom surface of the sheet layer 11 and electrically connecting the second electrode unit 13 and the co...
