E.5 Touchscreen Selection
Due to using pure glass instead of the coating, ELO SAW and IR touch are ideal
selection for touch solution on transflective LCD, they have lower reflectance rate
than traditional resistive and capacitive touchscreen that have coating on them.
Since our technology is based on transflective principle, the glass or sensor will
reduce the sunlight reflect out. It would have problem to use high reflectance sensor
or glass on transflective LCD.
Suggestion: ELO SAW and IR touch are recommended for touch screen solution on
transflective LCD.
