The performances of a display chip based on Fabry-Perot interferometer (FPI) array was stimulated theoretically.
Lighting by a single frequency laser, the grayscale of image pixels can be manipulated by transmission intensity
modulation of the FPIs which act as chip pixels. The F-P cavities were constructed by Lithium Niobate thin layer. The
cavity mirrors were deposited directly on the crystal surfaces. Using the converse piezoelectric effect of Lithium Niobate,
the cavity length was scanned by changing the applied voltage. Therefore, the single frequency laser transmission was
controlled. The electrodes were coated locally for corresponding chip pixel. A theoretical model for a display chip with
an array of 64×64 FPIs was built. The main parameters of the chip were optimized and the performances were stimulated.
The influences of mirror flatness, parallel of the cavity mirrors, linewidth and frequency stability of the lighting laser
were discussed. The simulation results indicated that this technique is promising for laser display.
