Patent number: 9128568Abstract: 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.Type: GrantFiled: July 13, 2009Date of Patent: September 8, 2015Assignee: New Vision Display (Shenzhen) CO., LimitedInventors: Ding Hua Long, Hai Hui Zhang, Hai Long Zhang

Patent number: 8525955Abstract: 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.Type: GrantFiled: January 31, 2012Date of Patent: September 3, 2013Assignee: Multek Display (Hong Kong) LimitedInventor: Ding Hua Long

Patent number: 8507800Abstract: 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.

Patent number: 8228306Abstract: 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.Type: GrantFiled: July 22, 2009Date of Patent: July 24, 2012Assignee: Flextronics AP, LLCInventors: Ding Hua Long, Hai Long Zhang, Hai Hui Zhang

Patent number: 8209861Abstract: A method for manufacturing a touch screen sensor assembly that includes providing a first transparent substrate, depositing a first non-metallic conductive layer onto the first substrate, removing the first conductive layer from a viewing portion of the first substrate, depositing a second non-metallic conductive layer onto the viewing portion, and removing portions of the second and first conductive layers to respectively form a first electrode pattern and a plurality of traces. The disclosed method also includes providing a second transparent substrate, depositing a third non-metallic conductive layer onto a viewing portion of the second substrate, removing portions of the third conductive layer to form a second electrode pattern, and bonding the first substrate to the second substrate using an optically clear adhesive. Each trace on the first substrate formed from the first conductive layer is electrically coupled to at least one electrode of either the first or second electrode patterns.Type: GrantFiled: December 2, 2009Date of Patent: July 3, 2012Assignee: Flextronics AP, LLCInventors: Ding Hua Long, Hai Long Zhang, Ying Yu

Publication number: 20110199328Abstract: A touch screen system that can sense when an object is held in continuous direct or indirect contact with a transparent substrate of the touch screen system as well as determine a location (e.g., X, Y coordinates) of the object in relation to the transparent substrate. The touch screen system employs dynamic surface capacitance technology to sense whether the object is held in contact with the transparent substrate and acoustic sensing technology to determine a position of the object that is contacting the transparent substrate.Type: ApplicationFiled: December 29, 2010Publication date: August 18, 2011Applicant: FLEXTRONICS AP, LLCInventor: Ding Hua Long

Publication number: 20100156846Abstract: 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.Type: ApplicationFiled: December 18, 2009Publication date: June 24, 2010Applicant: Flextronics AP, LLCInventors: Ding Hua Long, Hai Long Zhang, Hai Hui Zhang
