20100026659 | GLASS SUBSTRATE FOR CAPACITIVE TOUCH PANEL AND MANUFACTURING METHOD THEREOF - A capacitive touch screen panel includes top and bottom ITO coated glass sheets that may both be connected to detection electronics (e.g., a controller) by way of a single, normal flexible printed circuit connector. The ITO coated surface of each of the top and bottom glass sheets may face each other and a transparent material such as an optically clear adhesive may be disposed between the top and bottom glass sheets. In some embodiments, a number of spacers may be disposed between the top and bottom glass sheets to maintain a desired gap between the sheets. In other embodiments, the single, normal flexible printed circuit connector may generally reside in a single plane. | 02-04-2010 |
20100045620 | INTEGRATION DESIGN FOR CAPACITIVE TOUCH PANELS AND LIQUID CRYSTAL DISPLAYS - An integrated touch screen and display device includes a polarizer with a layer of transparent conductive material deposited thereon. A touch screen controller is coupled to electrodes of the transparent conductive layer to detect the location of touches by, for example, a finger or stylus. A method for producing an integrated touch screen and display device includes applying a transparent conductive coating to an outer surface of a polarizer of a display device, creating electrodes in the conductive coating, and coupling the electrodes to a touch screen controller. A double super twisted nematic display that includes a capacitive touch panel integrated into a compensation cell of the display is also provided herein. | 02-25-2010 |
20100139955 | CAPACITIVE TOUCH PANEL HAVING DUAL RESISTIVE LAYER - A patterned substrate for a touch screen sensor assembly that includes a plurality of electrodes that are formed from a first transparent conductive layer that has a first surface resistivity. The substrate also has a plurality of traces that may be used to couple the electrodes controller associated with the touch screen sensor assembly. The traces are formed from a second conductive layer that has a second surface resistivity that is less than the surface resistivity of the first conductive layer. The first and second conductive layers may be formed from indium tin oxide (ITO) having different surface resistivities. A second, similarly configured substrate can be provided and may be spaced apart from the first substrate by a dielectric spacer. | 06-10-2010 |
20100156811 | NEW PATTERN DESIGN FOR A CAPACITIVE TOUCH SCREEN - A capacitive touch sensor assembly that includes multiple regions is provided herein. Each of the multiple regions may include a top and a bottom array of patterned conductive material, such as indium tin oxide. The touch sensor assembly may further include a separate controller for each region, wherein the patterned conductive material in each region is coupled to the controller associated with that region. In one configuration, the top array of each region may not be aligned with the associated bottom region, such that multiple controllers may sense touches at a single point. Further, the patterned conductive material may include a plurality of rows and columns of diamond-shaped electrodes, wherein all of the electrodes have substantially the same surface area. | 06-24-2010 |
20100156846 | SINGLE SUBSTRATE CAPACITIVE TOUCH PANEL - A touch screen sensor assembly that includes a single substrate. In one embodiment, the assembly includes a first patterned transparent conductive layer (e.g., indium tin oxide) disposed on top of the substrate. The assembly also includes a second patterned transparent conductive layer disposed over the first conductive layer, with a layer of silicon oxide disposed therebetween. The silicon oxide layer functions to electrically isolate the first and second conductive layers, thereby eliminating the need for two substrates or a single substrate having transparent conductive layers on each of its top and bottom surfaces. The assembly may also be connectable to a single, non-bifurcated flexible printed circuit operative to connect the assembly to a controller. | 06-24-2010 |
20110181543 | Multi-driver touch panel - A novel capacitive touch system includes a first controller having a plurality of channels, a first sensor row having a first discrete sensor element and a second discrete sensor element, a second sensor row having a first discrete sensor element and a second discrete sensor element, a first sensor column, a second sensor column, and a first signal line electrically coupling one of the plurality of channels of the controller to both the first and second discrete sensor elements of the first sensor row. In a particular embodiment, the first controller includes a second channel electrically connected to both the first and second discrete sensor elements of the second sensor row. In another particular embodiment, the capacitive touch system includes a second controller having a plurality of channels, the first sensor column includes a first discrete sensor element and a second discrete sensor element, and a first channel of the second controller is electrically coupled to both the first and second discrete sensor elements of the first sensor column. | 07-28-2011 |

The first and second conductive layers may be formed from indium tin oxide (ITO) having different surface resistivities. A second, similarly configured substrate can be provided and may be spaced apart from the first substrate by a dielectric spacer. | 07-19-2012 |
20130194523 | Heater for Liquid Crystal Display - A heater for a display such as a liquid crystal display (LCD). The heater includes a transparent film, a transparent conductive layer formed on a surface of the transparent film, and an optically clear adhesive (OCA) disposed over the conductive layer. The heater may be laminated directly to a rear transparent (e.g., glass) plate of an LC cell of the LCD using the OCA in a manner that is substantially free of air gaps or bubbles between the heater and the LC cell. Front and rear polarizers may be respectively disposed on outside surfaces of the LC cell and the heater. | 08-01-2013 |
