Abstract: Electrical shield line systems are provided for openings in common electrodes near data lines of display and touch screens. Some displays, including touch screens, can include multiple common electrodes (Vcom) that can have openings between individual Vcoms. Some display screens can have an open slit between two adjacent edges of Vcom. Openings in Vcom can allow an electric field to extend from a data line through the Vcom layer. A shield can be disposed over the Vcom opening to help reduce or eliminate an electric field from affecting a pixel material, such as liquid crystal. The shield can be connected to a potential such that electric field is generated substantially between the shield and the data line to reduce or eliminate electric fields reaching the liquid crystal.

Abstract: A display that contains a column spacer arrangement which takes advantage of a protrusion on a TFT substrate is provided. One set of column spacers is disposed on top of the protrusion, while a second set of column spacers of substantially the same height as the first set of column spacers are disposed throughout the display. In this way, the display is adequately protected against deformation from external forces while at the same maintaining enough room to allow for a liquid crystal to spread out during the manufacturing process.

Abstract: A touch screen having touch circuitry integrated into a display pixel stackup. The touch screen can include a transistor layer, an LED layer and a first layer. The first layer can operate as an LED cathode during a display phase and as touch circuitry during a touch sensing phase. The transistor layer can be at least partially utilized for transitioning between the display phase and the touch sensing phase. The touch screen can be fabricated to reduce or eliminate damage to the LED layer.
