Abstract:
An image projection system for a display device, comprising:a first set of first LEDs for generating first light having a first wavelength during a first emission time frame;a second set of second LEDs for generating second light having a second wavelength during a second emission time frame, the second wavelength being different from the first wavelength;a first set of first optical fibers, each first optical fiber including at opposite ends thereof a first input terminal for receiving first light from at least one of the first LEDs and a first output terminal to propagate the first light from directly or indirectly to an imaging device;a second set of second optical fibers, each second optical fiber including at opposite ends thereof a second input terminal for receiving second light from at least one of the second LEDs and a second output terminal to propagate the second light directly or indirectly to the imaging device; anda display controller adapted to receive color image data from a data source and convert the color image data to at least first and second color frame sequential data for driving the imaging device, the display controller also being adapted to control the first and second emission time frames of the respective first and second sets of LEDs such that the imaging device implements the first color frame sequential data during the first emission time frame and the imaging device implements the second color frame sequential data during the second emission time frame.
