摘要： A gate signal adjustment circuit for a display is disclosed. The gate signal adjustment circuit can adjust a transition time of a gate signal used to drive data displaying. The adjustment can be to either speed up or slow down the transition time according to the requirements of the display. In an example, the gate signal adjustment circuit can include multiple transistors, where a first set of the transistors outputs the gate signal and a second set of the transistors outputs an adjustment to the gate signal. The second set of transistors can be the same or different sizes depending on the desirable number of adjustment options. The circuit can also include a control line coupled to the second set of transistors to control the adjustment output. Gate signal adjustment can reduce crosstalk in the display.

摘要： 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.

摘要： Display ground plane structures may contain slits. Image pixel electrodes in the display may be arranged in rows and columns. Image pixels in the display may be controlled using gate lines that are associated with the rows and data lines that are associated with the columns. An electric field may be produced by each image pixel electrode that extends through a liquid crystal layer to an associated portion of the ground plane. The slits in the ground plane may have a slit width. Data lines may be located sufficiently below the ground plane and sufficiently out of alignment with the slits to minimize crosstalk from parasitic electric fields. A three-column inversion scheme may be used when driving data line signals into the display, so that pairs of pixels that straddle the slits are each driven with a common polarity. Gate line scanning patterns may be used that enhance display uniformity.

摘要： An electronic device may have a display such as a liquid crystal display. The display may include a layer of liquid crystal material interposed between a color filter layer and a thin-film transistor layer. The thin-film transistor layer may be provided with capacitive touch sensor electrodes. Wide metal lines on the thin-film transistor layer may be used to inhibit parasitic capacitances during touch sensor mode. The color filter layer may include a layer of black masking material that surrounds the active display area. A light-curable adhesive may used to attach the color filter layer to the thin-film transistor layer. Openings may be formed in the black masking material and in the metal lines on the thin-film transistor layer. The adhesive may be cured by applying ultraviolet light to the adhesive through the openings in the black masking material and through the openings in the metal lines.

摘要： Setting a slew rate, e.g., a rising time or a falling time, of a scanning signal can be performed with a first operation, and a shunting resistance of the scanning line can be set with a second operation. A scanning system that scans a display screen, a touch screen, etc., can set a desired slew rate during a first period of time and can set a desired shunting resistance during a second period of time. A gate line system can sequentially scan gate lines to display an image during a display phase of a touch screen. The gate line system can, for example, increase the falling times of gate line signals. After the falling gate line signal has stabilized, for example, the gate line system can decrease the shunting resistance of the gate line.
