Abstract
The invention relates to a capacitive type touch screen which has low cost of materials and processing and improves reliability thereof. The capacitive type touch screen comprises an ITO glass substrate and is characterized in that the ITO glass substrate is a double-surface ITO glass substrate specifically; and two surfaces of the ITO glass substrate are connected mutually by a soft printing circuit board.
Description
(1) technical field
The present invention relates to the capacitive touch screen technical field, be specially a kind of capacitive touch screen.
(2) background technology
Existing capacitive touch screen structure is: stick other one deck ITO film and could constitute Sensor section on single face nano indium tin metal oxide (ITO) glass substrate, wherein the single face ITO film of single face nano indium tin metal oxide (ITO) glass substrate is an axially conducting circuit of X (or Y), it comprises the axially axial conducting circuit not of conducting circuit and Y (or X) of X (or Y), and one deck ITO film is the axial conductive membrane of Y (or X) in addition.The other one deck ITO film that sticks, its material and cost of processing height; And because in addition one deck ITO film need need form bridge joint with the cross section of single face ITO film on the single face ito glass substrate, it is in the process of fitting, and the instability that easily causes bridge joint is from reducing the reliability of capacitive touch screen.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of capacitive touch screen, its material and processing cost are low, and have improved the reliability of capacitive touch screen.
Its technical scheme is such: it comprises ito glass substrate, it is characterized in that: described ito glass substrate glass substrate is specially two-sided ito glass substrate, and the ITO layer on described two-sided ito glass substrate two sides interconnects by flexible printed circuit board.
It is further characterized in that: the positive ITO layer of described two-sided ito glass substrate is an X axis conducting circuit, its reverse side ITO layer is that Y-axis is to the conducting circuit, described flexible printed circuit board comprises connection X axis conducting circuit pack, connects Y-axis to the conducting circuit pack, the reverse side of described two-sided ito glass substrate is being pressed and is being connected described connection Y-axis to the conducting circuit pack, and described connection X axis conducting circuit pack cooperates pressing with the front of described two-sided ito glass substrate and is connected;
Described flexible printed circuit board has two non-conterminous grooves near a side of described two-sided ito glass substrate, projection in the middle of described two non-conterminous grooves is described connection X axis conducting circuit pack, described two non-conterminous groove two side portions are described connection Y-axis to the conducting circuit pack, and the described connection X axis conducting circuit pack when unassembled exposes to described connection Y-axis to the conducting circuit pack;
The reverse side of described two-sided ito glass substrate is being pressed by aeolotropic conductive film and is being connected described connection Y-axis to the conducting circuit pack, and the front that connects described two-sided ito glass substrate is being pressed by aeolotropic conductive film in described connection X axis conducting circuit pack bending back.
In the said structure of the present invention, because it adopts two-sided ito glass substrate, the ITO layer on described two-sided ito glass substrate two sides interconnects by flexible printed circuit board, it need not to mount in addition the ITO film again, so its material and processing cost are low,, need not to carry out bridge joint because the ITO layer on described two-sided ito glass substrate two sides interconnects by flexible printed circuit board, its connectivity is good, has improved the reliability of capacitive touch screen.
