Optical Clear Adhesive Film (S-LGB)

S-LGB is silicone based optical bonding sheet that is glued between the cover glass and display to eliminate the air gap so that it can provide perfect contrast and readability.

Please check more product features and advantages as below.

oca_01

Reducing the diffused reflection caused by the sunlight by removing the air gap with the application of OCA on the high reflex point—back of the tempered glass, the POL side—of the display device

Benefits
By removing the air gap between tempered glass and polarizer, brightness is improved. Improved brightness enables to minimize the loss of visibility. Better visibility under the direct sunlight provides improved contract in brightness. Possible to use in bad conditions including vibration and impact. Diffused reflection is minimized.

oca_02

- Improve the contrast range by minimizing the refraction of light occurred when the light of BLU passes the air gap.

The Principles of improvement in Picture Quality
- In the existing monitors, laptops, TVs, audio, video and navigation systems, different mediums exist between the tempered glass and the polarizer in the module structure. Such a structure causes lower brightness, the limit in improving picture quality visibility and viewing angle, and the diffused reflection caused by the sunlight. By applying OCA, such optical properties can be improved.
(available for TFT-LCD, STN-LCD, PDP, OLED and 3D-TV)

Advantage

  • Suitable to outdoor or harsh environment with silicone’s core properties, like low conductivity, low chemical reactivity, thermal stability and ability to repel water etc
  • Excellent readability and contrast with anti-reflection and anti-glare features.
  • With different thickness of OCA films, different depth of display can be implemented simply
  • No condensation nor fogging by eliminating air gap
  • Providing robust construction by shock and vibration absorption
  • No yellowing for more than 10 years
