At present, all design of communication systems, digital camera, camcorder and projector et cetera were requested with the smallest volume, convenient and carry-on product.
It would be best that a machine including multi function such as communication, photograph,and video, broadcast and share with friends. Since many years the mobile device has made much progress in size. Similarly the size of projector devices is demanded smaller from mini,pocket to Pico size which is significant to integrate into mobile device and other 3C product.
As this requisition, we need to think about not only the size but also the power consumption
of all key parts at first priority when designing the projector device.
In this thesis, for the light source we used the Red, Green and Blue LED with collimator to replace the conventional lamp, reflector and color wheel due to LED light source is the low power consumption, do not need to cool down with fan when the users turn on and off and reduce the size of the light source system. For illumination system we used lens array to take the place of Rod for reduces the total track of illumination system and to get high
uniformity above 82%.
For light separator, we use a new type TIR prism design which combines the projection lens and illumination system to decrease the volume and improve thecontrast of the projector.For the projection system, we used 8 elements such as 6 Spherical lenses and 2 Aspherical lenses to design the telecentric lens with 52 mm of the total track and do the evaluation and analyze the tolerance of the lenses with Code V optical software. Finally we
use the ASAP optical software to simulate the system of the power efficiency and uniformity.
