Abstract: A touch sensor panel having co-planar single-layer touch sensors fabricated on a single side of a substrate is dis-closed. The drive and sense lines can be fabricated as column- like patterns in a first orientation and patches in a second orientation, where each column-like pattern in the first orientation is connected to a separate metal trace in the border area of the touch sensor panel, and all patches in each of multiple rows in the second orientation are connected together using a separate metal trace in the border area of the touch sensor panel. The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.

Abstract: When a user operates a touch sensor panel having an LCD device outdoors or in a bright environment, light reflecting off the device can create glare. In order to reduce glare, a user can view the device through polarized filters such as polarized sunglasses. Doing so can reduce the visibility of the image displayed on the LCD. A quarter-wave retardation film can be added to the touch sensor panel's LCD device to mitigate these effects by producing circularly polarized light. However, adding a separate quarter-wave retardation film can increase the thickness and cost of manufacturing the touch sensor panel. Examples of the present disclosure are directed to a touch sensor panel constructed from a base film having quarter-wave retardation properties that can produce circularly polarized light. Because the base film has the desired optical properties, a separate quarter-wave retardation film may not be needed.

Abstract: Integrated touch screens are provided including drive lines formed of grouped-together circuit elements of a thin film transistor layer and sense lines formed between a color filter layer and a material layer that modifies or generates light. The common electrodes (Vcom) in the TFT layer can be grouped together during a touch sensing operation to form drive lines. Sense lines can be formed on an underside of a color filter glass, and a liquid crystal region can be disposed between the color filter glass and the TFT layer. Placing the sense lines on the underside of the color filter glass, i.e., within the display pixel cell, can provide a benefit of allowing the color filter glass to be thinned after the pixel cells have been assembled, for example.

Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

Abstract: An edge lit backlight unit 104 for a display is provided. In one embodiment, the backlight unit may include a light guide 106 configured to receive light from a source 108 and emit such light in a broad distribution 116 to a turning film 120 disposed over the light guide. The turning film 120 may be configured to redirect light received from the light guide toward a normal of the turning film. In one embodiment, the light guide may be configured such that peak light distribution therefrom occurs at an incident angle of approximately sixty degrees, with broad light distribution substantially occurring over an angular range between incident angles of thirty-five and eighty-five degrees. Additionally, in one embodiment, the turning film (120) may include multiple prisms (118) that receive and redirect the light emitted from the light guide (106), and that include apex angles of about sixty degrees. Additional edge-lit backlight units and methods are also disclosed.
