Patent number: 8107020Abstract: The invention pertains to an improved LCOS microdevice that eliminates colored lights required generally in a prior art system. According to one aspect of the present invention, the LCOS structure uses color filters directly in the LCOS chip. Depending on the number of colors being used, the color filters are arranged repeatedly according to a predefined pattern across an entire LCOS chip to coincide with pixels in the microdevice. When a white light is focused onto the LCOS microdevice, it reflects a color image that is then magnified and projected onto a display screen.Type: GrantFiled: January 14, 2008Date of Patent: January 31, 2012Assignees: Wuhan Splendid Optronics Technology Co., Ltd., Worship holdings limitedInventor: Darwin Hu

Patent number: 7728947Abstract: A nano-liquid crystal on silicon (nano-LCoS) chip having carbon nanotube (CNT) pillars that are grown on a glass substrate thereof. As the heights of the CNT pillars are uniform, the CNT pillars can function as spacers providing a uniform cell gap between the glass substrate and a silicon chip of the nano-LCoS chip. Also, being excellent electrical conductors, CNT pillars can form a part of the electrical connection between an outside voltage source and the indium tin oxide (ITO) layer formed on the glass substrate. The nano-LCoS chip includes nano-LCoS alignment keys that are formed in the silicon chip and connected to the CNT pillars. By applying the same voltage to the ITO layer and keys, a portion of the liquid crystal activated by the keys become transparent fiduciary marks for optical alignment of nano-LCoS chips.Type: GrantFiled: January 19, 2009Date of Patent: June 1, 2010Assignees: Wuhan Splendid Optronics Technology Co., Ltd., Sysview Technology, Inc.Inventors: Gihong Kim, Charles Chul-Whei Koo

Patent number: 7486287Abstract: An LCoS chip is designed to suppress electrical noise due to cross-talk between electrical components of the chip and stray light entered into the chip. The LCoS chip includes a silicon substrate having an array of memory cells formed the substrate. The chip includes a first polycrystalline silicon layer that forms word lines and a metal layer that forms bit lines, wherein bit lines are directed orthogonal to the word lines. The chip also includes capacitor storages formed on second and third second polycrystalline silicon layers. The second polycrystalline layer is disposed over the first polycrystalline silicon layer and over regions of the substrate not covered by the word lines. The metal layer includes shields to reduce cross-talk between neighboring bit lines as well as between the bit lines and the capacitor storages. A third polycrystalline layer is configured to reduce cross-talk between the bit lines and the word lines.Type: GrantFiled: August 15, 2006Date of Patent: February 3, 2009Assignees: Sysview Technology, Inc., Wuhan Splendid Optronics Technology Co.
