16-channel LED driver
The TLC5941 is a 16-channel constant-current-sink LED driver. Each channel has an individually adjustable 4096-step gray-scale PWM brightness control and a 64-step constant-current sink (dot correction), which adjusts the brightness variations between LED channels and other LED drivers. The dot correction and gray-scale control are accessible via a serial interface, while a single external resistor sets the maximum current value of all 16 channels. The TLC5941 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal and the thermal error flag (TEF) indicates an over temperature condition.

Large-format thin-film micrdiffusers
WaveFront Technology will introduce a large-format 42-in.-diagonal high-performance Tailored Micro-Diffuser (TMD®). These thin-film diffusers can replace conventional bulk diffusers or thick plates in direct-lit backlight units (BLUs) and improve performance in edge-lit BLU systems from mobile LCDs to large LCD TV monitors. Compared with conventional bead-type diffusers, the TMD® can provide the following advantages: higher brightness, better contrast and viewing angle, less thickness, and fewer layers (such as elimination of diffuser plate and/or prism film). Although BEF and DBEF (which are much more expensive then TMD® films) are still the best films for brightness enhancement, TMD® can provide a cost-effective alternative solution by replacing BEF and DBEF.
