MicroLens™ Optical Design Technology

MicroLens™ technology is a set of optical design innovations that provide optimum utilization of LEDs in edge-lit lighting applications delivering superior brightness and control of illumination. Through the use of proprietary optical modeling software and design techniques, the MicroLens features and their pattern in the LGP or film can be customized to efficiently spread the light across the entire lighting surface or focus it in specific locations depending on the application and illumination requirements. MicroLens features enable precise control of uniformity, exit angle and spread of the light, and can be implemented through a highly repeatable patterning process, enabling high-volume, custom-designed LGPs and films.

MicroLens technology is implemented with as many as 100,000 optical elements per square inch and can be printed on films as thin as 0.3mm. This enables ultra-thin solutions for LED edge-lit backlights in LCD displays and input devices for computing and consumer electronics products. With advanced modeling techniques, the MicroLens light distribution features can be varied by depth, shape, density and location to support a broad range of display and light fixture sizes with the fewest LEDs as compared to alternative edge-lighting techniques.

With Rambus' innovations such as MicroLens light distribution features, LED edge-lit lighting fixtures and displays can be illuminated with superior brightness and control while reducing the total number of required LEDs. All the benefits, lower power, wider color gamut, and thinner form factors, of LEDs can be realized in the most cost-effective manner. Further, the ability to place all of the LEDs along as few as one side of the display or light fixture greatly simplifies thermal management and provides greater flexibility in system implementations.

MicroLens technology is part of a portfolio of over 80 lighting patents that make LED lighting thinner, brighter and more cost effective, and further Rambus' mission of enriching the experience of consumer electronics.
