摘要
In order to make display device more useful and convenient, a device only using single liquid crystal (LC) panel as image source has been presented, and it can switch between 2D direct view and projection modes. Well controlled light path of the backlight module and sufficient image quality of the projection lens have been shown by simulation. The MTF (Modulation Transfer Function) of the projection lens is greater than 50% at 4 lp/mm, which is equivalent to 124.5um pixel size. Moreover, the projection image size is about the A4 size, with a throw distance of 462mm. Besides, the uniformity of collimation backlight reaches 70% and the FWHM (full width at half maximum) of angular divergence is less than 5°. The thickness of backlight light module is 15mm. Therefore, the display unit is compact and suitable for mobile application.
