摘要： A display having data lines that can be configured between a display mode and a touch mode is disclosed. The display can have sense regions for sensing a touch or near touch on the display during the touch mode. These same regions can display graphics or data on the display during the display mode. During display mode, the data lines in the sense regions can be configured to couple to display circuitry in order to receive data signals from the circuitry for displaying. During touch mode, the data lines in the sense regions can be configured to couple to corresponding sense lines in the regions, which in turn can couple to touch circuitry, in order to transmit touch signals to the circuitry for sensing a touch or near touch. Alternatively, during touch mode, the data lines in the sense regions can be configured to couple to ground in order to transmit residual data signals to ground for discarding.

摘要： With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce persisting visual artifacts by offsetting their effects or by distributing their presence among different colored sub-pixels. In some embodiments, this may be accomplished by using different write sequences during the update of a row of pixels.

摘要： Reduction of the effects of differences in parasitic capacitances in touch screens is provided. A touch screen can include multiple display pixels with stackups that each include a first element and a second element. For example, the first element can be a common electrode, and the second element can be a data line. The display pixels can include a first display pixel including a third element connected to the first element, and the third element can contribute to a first parasitic capacitance between the first and second elements of the first display pixel, for example, by overlapping with the second element. The touch screen can also include a second display pixel lacking the third element. The second display pixel can include a second parasitic capacitance between the first and second elements of the second display pixel. The first and second parasitic capacitances can be substantially equal, for example.

摘要： Disclosed embodiments relate to a thin-film transistor (TFT) for use in a display device. The display device may include a liquid crystal display (LCD) panel having multiple pixels arranged in rows and column, with each row corresponding to a gate line and each column corresponding to a source line. Each of the pixels includes a pixel electrode and a TFT. The TFT may include a metal oxide semiconductor channel between a source and drain. For each TFT, holes may be formed in the gate line in a region beneath the source and/or the drain. The holes may be formed such that the source and drain only partially overlap the holes. The presence of the holes reduces the area of the gate line, which may reduce parasitic capacitance and improve loading. This may provide improved panel performance, which may reduce the appearance of certain visual artifacts.
