LCD Repolarization

Film enhancements are an effective way to restore your LCD's brightness and viewability. Increase brightness, eliminate reflection and glare, prevent EMI interference, add privacy features and more, just by replacing or upgrading enhancement films.

The quality of your brightness is not only affected by your LCD capabilities but also largely on external factors. On an average sunny day, ambient sunlight can average 30,000 nits; for superior readability, LCD brightness must be high and screens must have clear optical quality. Exposure to extreme heat, cold or even just the age of the LCD may cause polarizers to warp or discolor, decreasing readability. LCDs purchased off the shelf are often not properly built for such conditions.

Making small additions or changes to the components of the LCD can easily bring your display's readability, brightness and optical clarity up to meet the environmental challenges your LCD faces.

AGDisplays offers a variety of film enhancements to improve your LCD's functionality and versatility. Brightness enhancing films are installed to help your LCD meet targeted brightness levels without any major redesigns or increase in power consumption. We offer protective films over coverglass that resist scratch and abrasions while minimizing reflection, increase contrast and sharpness. These solutions are not run on power but manipulate light in particular ways to achieve their specific attribute. The films are configured in the LCD build, not the LCD itself, so installation (or removal) is fast and will not affect the integrity of your display. Read below about our selection of films.

repolarization benefits

Our film products are retrofitted into any sized LCD. This service is a passive enhancement, meaning it is non-invasive.

  • Increased display contrast and readability
  • Enhanced optics and image clarity
  • Increased side-viewability
  • Provides a shielding layer to the front glass
  • Resistance to scratches and abrasions
  • Increased color sharpness
  • Privacy of information
  • Non-invasive: no change to electrical components
  • No need to readjust thermal management
  • No additional wattage consumption

anti-glare treatment

Anti-glare (AG) treatments minimize reflections from ambient lighting, noticeably improving readability.  The textured film diffuses specular reflections, removing the external reflection a user may experience. This film also improves scratch resistance. AG gives a matte appearance on the front of the LCD.

anti-reflective treatment

Anti-reflective (AR) film improves the durability and lifetime of your display surface. Anti-reflective properties increase the contrast and sharpness as well as decrease the reflection from your LCD screen without having to increase your LCD’s power consumption. Anti-reflective film can be identified as having a slightly purple tint.

brightness enhancing film

Brightness Enhancement Film or BEF film can increase the brightness of LCDs through utilizing refraction and reflection, increasing the efficiency of your backlight source. Light exits the LCD at a specific angle; light outside of this angle is reflected back into the LCD until it exits at the proper angle. Multiple BEF films used in unison can enhance light properties.

dual brightness enhancing film

Dual Brightness Enhancement Film (DBEF) is another thin film reflective polarizer that enhances LCD brightness. It uses light normally lost to absorption in the bottom LCD polarizer and redirects it until allowing it to exit the LCD backlight assembly. Using DBEF film in conjunction with BEF film can often offer the highest yield of light output.


Enhanced Specular Reflector (ESR) is designed to maximize the usage and distribution of light from the LCD’s light source. ESR film allows light distribution from the backlight to increase the LCD’s viewing angle. This film used with other brightness enhancing films can obtain the highest light output. A good solution for LCDs used in direct sunlight light.

privacy films

AGDisplays’ privacy film solution decreases viewing angles, allowing an increase in privacy by keeping information away from prying eyes. It works by controlling the distribution of light in relation to the viewing angle of the display. Light control films direct light only in the direction of the user; viewed from the front, the display is clear and bright. Viewed from either the left or right side, the display view is black.

Light Diffusion

Diffusion films improve LCD functionality by providing brightness uniformity throughout the active area. Light travelling through the stack up of an LCD will have no inherent direction and will be travelling in all directions. The function of the diffuser film is to redirect light in one direction, toward the next film. Employing diffuser films can provide up to 98% total light transmittance.

Quarter Wave Retarder

This film offers uniform birefringence, increasing the wide angle view performance of the panel while keeping haziness low. Birefringence refers to the double refraction of light seen through a transparent material. This film works to provide a uniform view of the images on the LCD when being viewed from the left, right, top or bottom.
