21.5 Inch OCR OCA Capacitive Touch Optical Bonding
21.5inch Capacitive Touch Optical Bonding With LCD display With OCR
/ OCA
Optical bonding technology introduction:
Optical bonding technology: Using OCR or OCA to bond LCD and touch
panel without air gap.
Advantages of optical bonding technology:
1. 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.
2. The touch panel is closely combined with LCD panel to improve
the module's strength.
3. The screen won't have dust again.
4. Optical bonding technology is more effective in reducing the
interference caused by panel noise to the touch signal.
5. Reduce the display of internal lines on the touch screen.(bottom
shadow decreasing).
6. The image is clearer.
Projected Capacitive Touch panel:
It’s a kind of projected touch panel with USB interface. It can
support win7, win8, win10 OS and can realize 10 finger point touch.
Capacitive Touch Screen Features:
1. Response speed fast, smooth touch
2. Using the latest projection touch technology <3mm touch
faster than other touch screen 3-5ms
3. Flat panel, more high-end atmosphere, eliminating infrared touch
screen surface with a groove edges are not allowed to shortcomings
4. Precision-touch capacitive screen is using the body's
current-sensing
5. Accuracy up to 99% proficient in writing, no break no drift
6. Completely dead 10-point touch really, any point can withstand
more than 50 million times touch
7. No ghost after the first calibration, drift-free
8. Explosion-proof and durable, complete physical steel
explosion-proof glass, scratch-resistant, anti-collision,
anti-radiation within the core capacitive touch ensure stable,
durable
9. Strong compatibility, support WindowsXP / 7/8 / 8.1 / 10 / CE,
Mac, Android / Linux and other operating systems
