Liquid Crystal Displays have emerged to become the dominant technology for displaying graphic and video content in a
diverse range of applications - from cell phones to very large TVs. Agoura’s PolarBrite technology was developed to
reduce the power consumption of LCDs.
LCD's are notoriously energy inefficient. Typically less than 10% of the light that is generated in an LCD actually gets
projected from the front of the display. The 90% inefficiency is lost as heat. The cost of the LCD is consequently higher
because larger power supplies, light sources, and heat management technology are required. The single biggest light
inhibitor and energy loss is in the rear polarizer film.
The traditional rear polarizer, which is an essential component of all LCDs, absorbs more than 50% of the light produced
by the display’s backlight. Agoura’s PolarBrite film is a same-cost substitute for the traditional absorbing rear polarizer.
However, the PolarBrite film does not absorb the unwanted polarization components of the backlight illumination.
Rather, it reflects them back into the backlight structure where scattering effects convert the unwanted components into
polarized light that is useable by the LCD. This process is known as polarization recycling and enables as much as 60%
more of the backlight illumination to be utilized by the LCD.
Agoura’s PolarBrite films are based on a proprietary new manufacturing method that enables wire grid polarizers to be
fabricated at very low cost and in areas large enough for even the largest LCD TVs.
