Assignment
To develop the Power Supply for a Flat-TV, the specification of the display part and the Backlight-Unit in particular, plays a crucial role. As many different displays need to be taken into account and because the display-prototypes as well as the display-specifications only become available at a late stage, it would be very useful to have a universal Backlight-Unit available for first testing of the Power Supply prototypes.

This universal Backlight-Unit should have a high flexibility in order to approach as close as possible all kinds of display-specifications, regardless of their size and technology (side-lit or direct-lit, with or without scanning possibility, different configurations of the LED-strings, …). Remark that only backlight-units based on LED’s are considered here.

The goal of this assignment is to define and realize a Universal Backlight-unit that should fulfill the following characteristics:
- High flexibility
- Able to approach the requirements for 32” up to at least 52” display-size
- Able to approach the following technologies :
o Side-lit
o Direct-lit
o 2D-dimming + scanning possibilities
- Easy to reproduce ( for multiple testing in parallel )
- Easy to change the configuration of the LED-strings
- Ease of use.

Remark : a first set-up of this assignment has already been initiated in a previous project.
