66‐3: Submillisecond‐Response 10‐Megapixel 4K2K LCoS for Microdisplay and Spatial Light Modulator

Abstract

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.

Fabrication of TiO2-Embedded Polyimide Layer with High Transmittance and Improved Reliability for Liquid Crystal Displays

“…The decay time of each cell was measured to determine the response speed, as shown in Figure 4 c. The gray-to-gray method, which is most commonly used, was used to measure the response speed. Here, the gray range was designated as dark gray and light gray for a transmittance of 10 and 90%, respectively [ 32 , 33 , 34 ]. Therefore, the decay time is the time taken to drop from 90 to 10% of the transmittance.…”

Vertical Alignment of Nematic Liquid Crystals Based on Spontaneous Alignment Layer Formation between Silver Nanowire Networks and Nonionic Amphiphiles

“…The measurement of response speed was based on gray-to-gray method, which is currently the most commonly used measure of response time. This method measures, in terms of time, the display transitions from dark gray to light gray (rising time) or from light gray to dark gray (decay time), whereby 10% transmittance was set to dark gray and 90% to light gray [34][35][36]. It can be seen in Figure 6 that the rising time of the conventional PI/ITO substrate is 22 ms and the decay time is 15 ms.…”

25‐1: Invited Paper: OLED Microdisplays for AR/VR Applications: Technical Approaches Toward Realization of over 10,000 Nits Full‐Color Panels

“…Of the many display candidates, microdisplays have great potential as proper solution for the application in AR/VR due to their small size and high resolution. [1][2][3][4] There are several types of microdisplays; Liquid Crystal on silicon (LCoS) [5,6], Digital Light Processing (DLP) [7,8], OLED microdisplay [9][10][11][12][13], and LED microdisplay [14]. In general, LCoS and DLP have been already used in projectors, projection televisions, and near-eye applications such as electronic viewfinders for digital cameras.…”
