P-151: Color Filter Liquid-Crystal-on-Silicon Microdisplays
نویسندگان
چکیده
We present a color liquid-crystal-on-silicon microdisplay that integrates color filters on silicon for colors. Fabrication parameters, color purity and light stability of this breed of microdisplays were characterized. A single-panel WXGA color projector based on this color filter microdisplay technology was demonstrated.

Fundamental Microdisplay Metrics for Near-To-Eye Applications: An Analysis of the Main Features of Microdisplays for Best Practice NTE Designs
Microdisplays are the enabling technology for head mounted and Near-to-Eye displays. In creating a colour image, FLC based LCOS technology is intrinsically and uniquely capable of a far more accurate rendering than any of the competitive technologies. LCD and OLED based technologies all suffer from fundamental limitations to image quality.
متن کاملApplication of Photoalignment Technology to Liquid-Crystal-on-Silicon Microdisplays
We applied photoalignment technology to liquid-crystal-on-silicon microdisplays and characterized their performance. A three-step photoexposure method was developed to solve problems with alignment disturbances on reflective silicon panels. The azimuthal and polar anchoring energies of photoalignment layers produced by this method were high and comparable with that of rubbed polyimide layers. W...
متن کاملFast-response liquid crystals for high image quality wearable displays
We demonstrate two ultra-low viscosity liquid crystal mixtures to enable field-sequential-color wearable displays for low temperature operation, while keeping a wide color gamut. Our mixtures offer ~4X faster response time than a commercial material at 20°C and ~8X faster at −20°C. Other major attractive features include: (1) submillisecond response time at room temperature and vivid color even...
متن کاملDesign of a polarized head-mounted projection display using ferroelectric liquid-crystal-on-silicon microdisplays.
It has been a common problem in optical see-through head-mounted displays that the displayed image lacks brightness and contrast compared with the direct view of a real-world scene. This problem is aggravated in head-mounted projection displays in which multiple beam splitting and low retroreflectance of a typical retroreflective projection screen yield low luminous transfer efficiency. To addr...
متن کاملOptimization of Bend Cells for Field-Sequential Color Microdisplay Applications
The geometry and waveforms of optically compensated bend cells are optimized for fieldsequential color microdisplay applications. A unique software package based employing D. W. Berreman’s modeling software as a calculation engine is used to determine the critical voltages, dynamics and optics of reflective bend cell microdisplays. The optimized configuration features an on-off time of less tha...
