Publication number: 20120050175Abstract: A touch panel of a display disposed on a display panel includes a transparent substrate, a transparent electroconductive layer and an electrode pattern layer vertically stacked together. The electrode pattern layer includes two opposite parallel X-side electrodes and two opposite parallel Y-side electrodes, all of which surround a rectangular area and are disposed on a periphery of the transparent electroconductive layer. Also, a plastic film is disposed on a side surface of the electrode pattern layer opposite the transparent electroconductive layer. Thus, the touch panel needs not the processing of the surface hard layer, so that the manufacturing processes are simplified, the production yield is increased and the manufacturing cost is reduced when the large-scale touch panel is manufactured. Meanwhile, the interference of electromagnetic waves on the transparent electroconductive layer and the electrode pattern layer can be reduced, and the touch certainty and precision can be enhanced.Type: ApplicationFiled: August 28, 2010Publication date: March 1, 2012Inventors: Wu-Tung KAO, Chih-Ping Shu, Chi-Feng Chiu

SURFACE CAPACITIVE TOUCH PANEL WITH MULTI-POINT TOUCH STRUCTURE AND MULTI-POINT TOUCH METHOD THEREOF
Publication number: 20120050202Abstract: The invention relates to a surface capacitive touch panel capable of simultaneously determining different touch points, and a method thereof. The touch panel includes a transparent substrate, a transparent electroconductive layer and an electrode pattern layer. The electrode pattern layer includes at least one first X-side electrode, at least one second X-side electrode, at least one first Y-side electrode and at least one second Y-side electrode, which surround a rectangular area and are formed on a surface periphery of the transparent electroconductive layer. The impedances of the X-side and Y-side electrodes are configured in an ascending manner or a descending manner with a common difference or a common ratio toward the same side, so that impedances of two touch points on the same horizontal or vertical line of the touch panel have a gradient phenomenon to prevent currents from offsetting each other when the two touch points are moved.Type: ApplicationFiled: August 27, 2010Publication date: March 1, 2012Inventors: Wu-Tung KAO, Chih-Ping Shu, Chi-Feng Chiu -
Publication number: 20120050174Abstract: A display includes a display panel and a touch panel with a multilayer structure disposed on the display panel. The touch panel includes an ITO film, a transparent electroconductive layer and an electrode pattern layer stacked vertically. The electrode pattern layer includes two parallel X-side electrodes and two parallel Y-side electrodes, all of which surround a rectangular area and are disposed on a peripheral portion of the transparent electroconductive layer. A mother glass layer is stacked above a side surface of the electrode pattern layer opposite to the transparent electroconductive layer. Thus, the touch panel needs not the processing of the surface hard layer, so that the manufacturing processes are simplified, the production yield is increased and the manufacturing cost is reduced. Meanwhile, the interference of electromagnetic waves on the transparent electroconductive layer and the electrode pattern layer can be reduced, and the touch certainty and precision can be enhanced.Type: ApplicationFiled: August 27, 2010Publication date: March 1, 2012Inventors: Wu-Tung KAO, Chih-Ping Shu, Chi-Feng Chiu

Publication number: 20120050204Abstract: A touch panel of a display has an impedance adjusting structure for enhancing the detection precision of touch points and includes a transparent substrate, a transparent electroconductive layer and an electrode pattern layer. The electrode pattern layer includes two parallel X-side electrodes and two parallel Y-side electrodes, which surround a rectangular area and are formed on a periphery portion of the electroconductive layer. Each of the X-side and Y-side electrodes is composed of carbon paste sections and silver paste sections arranged in a neighboring manner. Output currents of the X-side and Y-side electrodes are adjusted according to ratios of the carbon paste sections to the silver paste sections, wherein the carbon/silver paste sections are spaced apart by gaps, which are the same, ascend or descend. According to the design, the specific impedance adjustment of the electrode pattern layer can be performed according to the special requirement in the used environment.Type: ApplicationFiled: August 27, 2010Publication date: March 1, 2012Inventors: Wu-Tung KAO, Chih-Ping Shu, Chi-Feng Chiu
