Miniaturization Design And Key Structure Optimization Of LCD Projector

As a large screen display device, LCD projector is applied in many fields. However, its slightly bulky volume and exorbitant price are important factors to restrict the development of this kind of product. Therefore, the miniaturization, low cost and high brightness LCD projector products for users and enterprises have significance.First, the optimization design of the optical system is carried out. Affected by the characteristics of the components, the miniaturization of optical elements will decrease light utilization rate. By designing of bulb reflector shape, enhancing the integral mirror fabrication and selecting the suitable polarizing plate material, the light utilization rate of small light machine is improved; and through the experimental method, the fixture verification platform design effect and finally get compact and high brightness light machine.Additionally, the frame structure is designed to make the whole machine miniaturization. In order to reduce the number of parts, save the cost and improve the utilization ratio of space, the frame structure is designed as the foundation of the projector, and the intensity of the machine is improved.Moreover, the space of the LCD projector is constrained by the cooling air path, which is designed to combine the heating characteristics of each element. The light bulb cooling adopts the variable wind path to realize the whole week working mode of the whole machine. The filter dust and noise reduction are improved to effectively promise the normal operation of small LCD projector.Upon examination at A4 size, the LCD projector has reached 3000 lm high brightness display. With its characteristics of small volume, light weight, high brightness and pricing economy, the products have regions and achieved good response in the market, which can also provide reference for the same type product development.
