Rambus Inc. buys Imagine Designs Inc.'s lighting and display portfolio of patents and technology for general lighting, LCD backlighting and MEMS displays.

Following the acquisition, Brian Richardson, Imagine Designs founder and principal inventor, will serve as a technical director in Rambus' Lighting and Display Technology business.

''A few of the innovative technologies developed by Imagine's team are colour changing and optics systems used on most live concert productions, a computer server and various other computer equipment, bicycle components, and even a bobsled used in the Olympics,'' according to Imagine Designs.

''Imagine's new light valve technology can be seen in action to the right. This demonstration prototype has a contrast ratio in excess of 5000:1 and is over 90 per cent efficient. Imagine is developing this new technology, with its new optics, for flat panel displays,'' according to the firm.

Rambus has been expanding its lighting intellectual property. Launched in 2009, its lighting and display business includes edge-lit LED optical designs, MicroLens light distribution features, and light guide panels and multi-function film manufacturing technologies.

In 2009, Rambus, a technology licensing company, acquired technology and a portfolio of advanced lighting and optoelectronics patents from Global Lighting Technologies Inc. (GLT). These patented innovations, which include MicroLens light distribution technology, broadened Rambus' solutions for computing and consumer electronics. As part of this agreement, Rambus paid GLT Rs.119.25 crore ($26 million).

Last year, Rambus acquired a portion of Uni-Pixel's IP portfolio relating to dynamic backlighting, field sequential colour displays and time multiplexed optical shutter display technology for Rs.10.32 crore ($2.25 million). In addition, Uni-Pixel has entered into an engineering services agreement with Rambus for future collaboration and technology development.

Also last year, GE Lighting, a unit of the General Electric Company's appliances and lighting business, signed a licensing agreement for the use of Rambus' lighting patents, reference designs and manufacturing process know-how.
