17 Inch LCD Touch Module Optical Bonding with PCAP Touch with 1280*1024
Optical Bonding Introduction: it is using OCR or OCA to bond LCD and touch panel without air gap.
Advantages of Optical BondingTechnology:
Optical bonding technology eliminates air gap between LCD and touch panel, which helps to reduce the reflection between LCD panel and touch panel (reduce 75%), and it can make the module screen look more transparent and enhance the display effect of the screen.
The touch panel is closely combined with LCD panel to improve the module's strength.
The screen won't have dust again.
Optical bonding technology is more effective in reducing the interference caused by panel noise to the touch signal.
Reduce the display of internal lines on the touch screen.(bottom shadow decreasing).
The image is clearer.
Description Of Touch Panel: Capacitive Touch Panel is to use the working current of induction of human body.The operational principle of the projected capacitive touch panel: There are two layers of the ITO layer under the surface of glass. This ITO layer respectively forms the electric field of X axis and Y axis, which can keep balance by crossing the surface of the class. Once the fingers approach the glass surface, the fingers and the electrode X axis or Y axis will form a new electric field, which can make the local capacitance change. Then the controller will determine the location based on capacitance changes.
