Abstract :
In this paper, two considerations were presented for designing pico-projector based-on LCoS panel and LED. To have a clear picture, LED duty cycle has to be less than 50% of whole possible LED illumination times. And, a constant current circuit is needed to maintain a white balance of picture.
