- W4384702561 abstract "The market demand for portable projectors has been high because they are portable and can be easily used on different occasions, such as business demonstrations, educational training, home theater, etc. With the continuous progress of technology, portable projectors have more and more diversified functions, such as supporting wireless screen projection, built-in battery, HD projection, etc., which also further increase the market demand. A projection system based on the LED microarray was designed. The system consists of a display unit and a projection objective lens. A 10mm×7.5mm self-emitting LED microarray was used as the display unit, and the projection objective was designed with an optical design zemax. The projection objective has antiremote optical structure with full field of 66 and focal length of 8.5mm; At the spatial frequency of 85 lp/mm, the modulation transfer function MTF is greater than 0.5 and the distortion is less than 1%. Meet the design requirements of the projection system. The projection system has the advantages of small size, simple structure, good projection effect and convenient processing, which can provide reference for the development of the third generation projection technology." @default.
