Optically Bonded Anti-Reflective Cover Plate for TFT-LCD

Tue, 07/27/2010 - 10:20am
OSD now offers Optical Bonding Technology to attach cover lenses; anti-reflective glass, plastic, or touch sensor directly onto our range of high brightness flat panel displays. This technology allows the elimination of the air gap between the cover plate or touch sensor and the TFT panel.

By using an adhesive that closely matches the index of refraction of the panel and the cover plate the total reflectance of the module can be reduced to as low as 0.2%, dramatically increasing the contrast ratio in a high ambient light environment. Other benefits of this process include improved impact and shock resistance.

Optical bonding is available as an option on many of OSD’s small to medium size TFT modules. Currently these include the 3.5” (320x240 QVGA), 4.3” (480x272 WVGA), 5.7” (320x240 QVGA), 5.7” (640x480 VGA), 7.0” (800x480 WVGA) & 8.0” (800x480 WVGA) display modules.

Applications targeted for this product include OEM Automotive GPS/Information display centers and Industrial control panels.
