Abstract

To improve the resolution of projective image of a Thin Film Transistor-Liquid Crystal Display (TFT-LCD)

a method was proposed by using a piezo-stage to drive the TFT-LCD movement in

and

directions to implement the pixel-multiplexing of the TFT-LCD. The hardware configuration of the TFT-LCD was introduced

and the principle of improving the resolution of projective image by the pixel-multiplexing was presented. On the basis of accuracy demand of displacement movement to be 10 nm

the moving mechanism that can achieve a higher precision was chosen. Furthermore

three kinds of test schemes were proposed to prove the obtained results

and a experimental platform was constructed to verify the correction and efficiency of test principle. Experimental results show that the image resolution projected by the TFT-LCD has been doubled in

and

directions

respectively

and total pixels are four times that of traditional imaging method. Proposed method changes the situation that the resolution of a star simulator is limited by that of the display device.
