“…As a result, the silicon oxide was widely used as the alignment layer of the LCoS microdisplays in VA mode. [10][11][12][13][14][15] In this research work, the silicon oxide was also adopted as the alignment layer for the process of VA mode CF-LCoS microdisplay. The color filter array was prepared on the silicon substrate by the same process as reported in our previous works.…”

The process of vertical alignment (VA) mode color filter liquid crystal on silicon (CF-LCoS) microdisplay was developed. In order to minimize the fringing field effect in small color pixels, a three dimensional (3D) optical model was established and performed to analyze this VA mode CF-LCoS microdisplay. The simulated result was compared with the experimental data and they coincided well. Optimization of this breed of VA mode CF-LCoS microdisplay was proposed with optimal pretilt angle and pixel size. With the pretilt angle of 86 degrees and the pixel size of 15 μm, the color purity of the VA mode CF-LCoS microdisplay could attain more than 60% National Television Standards Committee (NTSC) level, and the contrast was larger than 400.

“…The initial system was developed in partnership with JVC, utilizing their 33-mm-diagonal analog-backplane QXGA-resolution (2048 × 1536) devices. 17 These devices provided the highest-performing, commercially available, vertically aligned LCOS devices existing at the time of concept development in 2002.…”

Abstract— A digital cinema projector that utilizes three JVC QXGALCDs, and provides 12,000 lumens, 2000:1 contrast, and 3‐Mpixel resolution was developed. This system, which was described in a prior paper (see Ref. 10), has a novel optical configuration based on the use of intermediate imaging optics and wire‐grid polarizers and is described in greater detail in this paper. The polarization optics, including the polarization compensators, contribute to a system that provides high contrast at a low f/#, with a wide color gamut and minimal color shading at high power.

“…1 But thus far, D-ILA has been limited to high-end professional applications. 2 The new 720P device is targeted at consumer applications and employs a fully digital driving method. Many have tried to drive liquid crystals (LCs) digitally, [3][4][5] but until now they have not obtained good picture quality and reliability at the same time.…”
