Patent number: 7839568Abstract: A bi-stable projection screen includes a light diffusion unit and a bi-stable display unit stacked together. The bi-stable display unit, when actuated, selectively operates in a first mode or a second mode. When operating in the first mode (e.g., a transmission mode or a reflection mode), the bi-stable display unit receives a projection light from a front projection or a rear projection, and emits the projection light after modulation. When operating in the second mode (a non-transmission mode or a non-reflection mode), the bi-stable display unit is a pattern to become a part of a scene. The light diffusion unit receives and diffuses the modulated projection light to be perceived by human eyes.Type: GrantFiled: March 27, 2008Date of Patent: November 23, 2010Assignee: Industrial Technology Research InstituteInventors: Chun-Hsiang Wen, Wen-Hsien Wang, Yaw-Ting Wu, Hui-Lung Kuo

Patent number: 6927911Abstract: The light-guide module for emitting particular polarized light beams includes a splitter for separating non-polarized light beams, a transformer for converting polarization of light beams, and a non-polarized light source. The non-polarized light source emits light beams. Particular polarized light beams pass the splitter and other light beams are reflected by the splitter. Polarizations of reflected light beams and of light beams emitted by the non-polarized light source are converted by the transformer so as to separate the light beams later. Thus the light-guide module for emitting particular polarized light beams loses relatively little light energy.Type: GrantFiled: June 9, 2003Date of Patent: August 9, 2005Assignee: Industrial Technology Research Institute/Material ResearchInventors: Ming-Lang Tsai, Chun-Hsiang Wen, Hui-Lung Kuo, Kuo-Tung Huang, Yaw-Ting Wu, Ying-Chiang Hu, Chih-Kng Lee, Liang-Bin Yu, Ping-Chen Chen, An-Shun Liu

Patent number: 6383694Abstract: A method of manufacturing a color filter for a reflective liquid crystal display is disclosed. The method comprises the following steps: 1) coating a layer of positive photoresist on a reflective layer or reflective substrate, and exposing the photoresist layer to a light via a mask having a fine pixel pattern so as to form at least three exposed regions of different exposed energy in the photoresist layer, 2) Removing one of the existing exposed regions having a largest exposed dose by the use of an alkaline developer solution so as to expose the surface of the electrically conductive reflective substrate corresponding to the removed region; and electrodepositing a color paint on the exposed surface of the reflective substrate to form a color filter layer of one selected color, 3) repeating step 2) to remove the other exposed regions in the photoresist layer and proceeding with an electrodeposition process with another color paint until a color filter layer of all desired colors is completed.Type: GrantFiled: August 25, 2000Date of Patent: May 7, 2002Assignee: Sumitomo Chemical Company LimitedInventors: Yaw-Ting Wu, Chun-Hsiang Wen, Shu-Huei Cheng, Ming-Hsiang Chan, Jun-Ichi Yasukawa, Hajime Kuwahara
