Problems solved by technology

Since this mainstream touch screen off-line material uses double nano-indium tin oxide (Indium Tin Oxides, ITO) film glass, the aesthetics of the shape design will be greatly reduced (generally it can only be designed as a rectangle), and in You can only use the internal card when installing the machine, and the off-line material ITO glass will inevitably crack and shatter when it is dropped or squeezed

Embodiment Construction

[0026] refer to figure 1 , which is a three-dimensional exploded view of an embodiment of the touch screen provided by the present invention; as shown in the figure, this embodiment mainly includes the following layers of structure:

[0027] circuit layer 1;

[0028] The upper line ITO film 2 attached to the upper surface of the circuit layer;

[0029] A lower conductive printed circuit (Print Circuit, PC) board 3 attached to the lower surface of the circuit layer.

[0030] During specific implementation, the circuit layer specifically includes:

[0031] On-line circuit layer 11;

[0032] Offline circuit layer 12;

[0033] The isolation layer 13 is arranged between the upper line circuit layer and the lower line circuit layer.

[0034] Wherein, a flexible printed circuit 4 (FlexiblePrinted Circuit, FPC) provided with leads is also drawn out from the circuit layer 1 ( figure 1 not shown, refer to figure 2 ).

[0035] In addition, the upper layer of the ITO film on the ...

Abstract

The invention discloses a resistance-type touch screen, which is characterized in that the resistance-type touch screen comprises a circuit layer, a flexible printed circuit educed from the circuit layer, an upper ITO film integrated on the upper surface of the circuit layer; a mirror integrated on the upper ITO film through adhesive, and a lower conductive PC board integrated on the lower surface of the circuit layer. Correspondingly, the invention also discloses a manufacturing method of the resistance-type touch screen. The invention avoids various shortcomings caused by glass materials used in the prior art, such as poor bending degree, poor pressure resistance and bad anti-attack performance, and also avoids the limitations that only the rectangular and inner-clipping way can be used.

Description

technical field [0001] The invention relates to touch screen technology, in particular to a resistive touch screen and a manufacturing method thereof. Background technique [0002] The touch screen is an input device that can complete corresponding operations by touching the viewed interface. It can make the operation of the system simple, visible and intuitive, and can omit the addition of separate buttons, so that the scope of use becomes wider and wider. And now the mainstream touch screen off-line material is glass. Since this mainstream touch screen off-line material uses double nano-indium tin oxide (Indium Tin Oxides, ITO) film glass, the aesthetics of the shape design will be greatly reduced (generally it can only be designed as a rectangle), and in The internal card can only be used during installation, and the ITO glass, the off-line material, will inevitably crack and shatter when dropped or squeezed. And because the bending degree of the glass is limited, it h...
