Description
Technical field
The utility model relates to capacitance-type touch screen technology, the OGS capacitive touch screen that especially a kind of METAL builds bridge, and belongs to field.
Background technology
Capacitance touch screen Market competition, only have minimizing manufacturing cost and product to possess singularity and just have the market competitiveness, current main flow and the good capacitive touch screen structure of performance is ITO builds bridge and METAL builds bridge, METAL bridging structure is lower than ITO bridge formation cost, but can see bridge point after the LCD that fits.This has just become the disadvantage of METAL bridging structure product.And existing METAL infrastructure product is run business into particular one METAL bridge and also can be met, but existing METAL bridging structure needs to climb (METAL bridge point will weigh above OC and climb), then easily cause METAL bridge to break.
Summary of the invention
For solving an above existing difficult problem, the utility model discloses the OGS capacitive touch screen that a kind of METAL builds bridge, and sees the problem of bridge point after solving traditional capacitance touch screen METAL bridge formation laminating LCD.
The OGS capacitive touch screen that a kind of METAL builds bridge, comprise the glass substrate be cascading, IM film plating layer, BM frame pattern layer, METAL conductor layer, OC protective seam and ITO patterned layer, SINX protects the shadow layer that disappears, described IM film plating layer is arranged on the glass substrate back side, described BM frame pattern layer is positioned at the surrounding of described glass substrate, between touch-screen X/Y electrode and and be provided with the first conductive layer between touch-screen X/Y electrode and touch-control IC, described OC protective seam upper end is provided with the second conductive layer, described IM film plating layer is made up of a kind of film of SIO2 or NB2O5 or SIO2 and NB2O5 combined films, described first conductive layer is made up of the combined films of METAL and SIO2, and the second conductive layer is made up of indium oxide tin film, bridge point live width in described METAL conductor layer is 3-7um, and the bridge point live width in described OC protective seam is 45-55um.
Further: the etching of described conductor layer No.1 has METAL conductor layer, this METAL conductor layer is combined by one or more of molybdenum alloy or aluminium alloy or aldary or silver alloy.
Beneficial effect: the utility model uses METAL bridging structure, electrical property effect is then built bridge effective than ITO, can't see bridge point, again reduce cost simultaneously after capacitance touch screen METAL bridge formation laminating LCD.
