“…The 1T DRAM LCOS pixel circuit of Figure 6(a) is typically used in analog mode but has also been used in digital PCM mode [7], illustrating the flexibility of the DRAM approach. The p-Si TFT circuit of Figure 6(b) adds a MOSFET for voltage to current conversion, making it suitable for OLEDs but leaving its output subject to manufacturing variations in the threshold voltage and carrier mobility.…”

Microdisplays are used in many applications from electronic viewfinders to rear projection television and even in nondisplay applications such as printers. There exist a number of microdisplay technologies based upon different materials and physical systems. We outline the various classes of microdisplay along with their suitability for certain applications. We describe an emerging microdisplay technology based on a combination of polymeric organic electroluminescent material and CMOS active-matrix backplane, making comparisons with conventional OLED display technology and other microdisplay technologies. We focus, in particular, on a novel active matrix addressing approach for the emerging technology.

“…Liquid crystal on silicon (LCOS) technology [1][2][3][4][5][6][7][8] has been an active area of research since the early 1980's. By employing silicon very-large-scale integration technology and complementary metal oxide semiconductor (CMOS) circuitry, complex functionality can be realized by using a silicon backplane with the associated scalability of pixel size and active area.…”

A method to measure the optical response across the surface of a phase-only liquid crystal on silicon device using binary phase gratings is described together with a procedure to compensate its spatial optical phase variation. As a result, the residual power between zero and the minima of the first diffraction order for a binary grating can be reduced by more than 10 dB, from -15.98 dB to -26.29 dB. This phase compensation method is also shown to be useful in nonbinary cases. A reduction in the worst crosstalk by 5.32 dB can be achieved when quantized blazed gratings are used.

“…To achieve a high pixel density with the least bumpy pixel, we utilized a pixel circuit based on the one-transistor cell of the familiar dynamic random access memory (DRAM). Other groups working on FLC/VLSI devices have followed a similar approach [4,5,6]. The challenges with this approach are to minimize pixel mirror corrugation and to minimize light sensitivity.…”

Black Forest Engineering, Colorado Springs, Colorado 80962-2083 We have made 128x 128 and 256x 256 spatial light modulators (SLMs) using active backplanes fabricated through a commodity silicon foundry and incorporating a thin ferroelectric liquid crystal (FLC) light modulating layer at the backplane's surface by means of post-processing of individual foundry die. These electrically addressed devices exhibit optical rise and fall times as short as 105 ps, with contrast ratios in images as high as 100:1, and in zero-order diffracted light as high as 200:1. Total optical throughput to the zero-order diffracted beam exceeds 10% for the 256 x 256 devices and 17% for the 128 x 128 devices. Frame update times shorter than 100 s, corresponding to image information throughput of greater than 80 MBytes/s, were realized by employing pipelining techniques in conjunction with a wide digital input word.
