GE Advanced Materials is expanding its Illuminex diffuser film family of optical films for liquid crystal display (LCD) backlighting applications into complete display solutions for applications such as televisions, notebook PCs, computer monitors and automotive GPS displays. These materials provide both top and bottom diffuser film solutions in LCD backlight modules to help enhance performance under demanding environmental reliability conditions and greatly expand GE's wing-to-wing materials solutions capabilities for the global electronics industry.
GE's Illuminex diffuser films offer key advantages over traditional coated polyethylene terephthalate (PET) films by eliminating the coating, which can experience failures from flaking, voids, and scratching of light guides, resulting in poor yields.
GE continues to expand its technology resources in the area of electronics at its Shanghai China Technology Centre.
At the centre, GE is currently developing next-generation Illuminex display products, working closely with customers to accelerate the product development process.

In addition, GE will continue to expand manufacturing capabilities for Illuminex diffuser films, which includes the Pacific region, in 2006.
'The proliferation of new products with LCDs and the trends toward larger sise and greater thinness have created challenges for manufacturers in terms of higher temperature performance, optical quality and durability', said Todd Hoff, Market Director - Displays, GE Advanced Materials.
'By extending our Illuminex diffuser film portfolio into full solutions for LCDs and making further global investments in this product line, GE will be able to offer comprehensive performance and quality advantages in a range of applications'.
Illuminex diffuser films combine the advantages of GE's expertise in Lexan polycarbonate optical-quality resins with a Class 10,000 low-stress, optical-quality clean room environment.
These films feature excellent optical properties that are 'built into' the film formulation and/or calendared into the film surface - compared with traditional PET films that are coated - to help deliver an excellent combination of cost-effective quality and performance.
Further, Illuminex diffuser films may help increase yield compared with coated diffuser products, which scratch more easily and can fail during handling and assembly.
As LCDs continue to evolve, becoming larger and thinner with an increased number of light sources, there is a need for higher temperature and humidity performance.
GE Advanced Materials' products help address these requirements, offering a heat deflection temperature (HDT) of 130C and outstanding performance in high-temperature and high-humidity conditions.
