The NCTU PCU-3-02 10-megapixel 4K2K (max. 4160x2464) LCoS panels with LCM-1107 nematic LC were assembled and evaluated. The results of both 1.2-inch 4K2K (~4,000 PPI) amplitude type LCoS microdisplay and 0.7-inch 4K2K (~7,000 PPI) phase-only type LCoS spatial light modulator (SLM) can achieve 1~2 ms response time at T=45 o C. Meanwhile, the phase linearity, precision and accuracy of 4K2K LCoS-SLM were assessed in this work. These new LCoS schemes will potentially be utilized in color-sequential, holographic, virtual and augmented reality display.

A digital modulation is the use of pulse width modulation on liquid crystal to create gray scale and phase level. The operation in time domain has greater RMS voltage accuracy for finer gray scale and high pulse frequency by Terminated Write Pointer let liquid crystal behaves more smoothly.

A 4,000 PPI phase-only NCTU PCU-3-01 LCoS-SLM filled with UCF-L1 NLC was assembled and evaluated. The resulting LCoS panel possessed 1.6 ms of linear-full-phasemodulation response time under digital driving (V w = 4.5 V, V b = 0.3 V) at T = 45 o C. The 3D holographic images show that most diffracted light is transferred within 2 ms. Meanwhile, a low-latency driver solution based on 1920 x 640 at 240Hz (equivalent to 4000 PPI) input frame rate and 720 Hz data frame rate were presented.
