With touch panel attached to LCM, the display suffers not only brightness going down but also the deteriorating in display quality. Especially the reflection of ambient light causes the dark image being not as dark as it supposed to be.
By adding the process of Optical Bonding, we can reduce the brightness loss and avoid the influence of ambient light. Optical bonding technique fills the air gap with Optical Clear Adhesive or OCA. While the optical index of OCA is designed to be very close to that of glass, light reflection at those two interfaces is minimized. Since less ambient light is bounced off the interfaces with optical bonding, the dark image remains as dark as it should be and the contrast ratio as well as the color saturation are restored back to the level when touch panel was not there. Likewise, back light of LCM experiences less reflection loss when it propagates through the interfaces with OCA, and the brightness off the touch panel is up as if the TP was not there.
