摘要： Index matching for touch screens is provided. An index matching stackup for a touch screen can be formed including a substantially transparent substrate, a substantially transparent conductive layer disposed in a pattern, and an index matching layer for improving an optical uniformity of the touch screen. The index matching layer can also be designed to operate as a dual-function layer. In one dual-function design, the index matching layer design performs both index matching and passivating the conductive layer. In another dual-function design, the index matching layer performs both index matching and adhesion of layers. The index matching layer can also be designed to serve all three functions of index matching, passivating, and adhering.

摘要： A touch screen including display pixels with capacitive elements is provided. The touch screen includes first common voltage lines connecting capacitive elements in adjacent display pixels, and a second common voltage line connecting first common voltage lines. The pixels can be formed as electrically separated regions by including breaks in the common voltage lines. The regions can include a drive region that is stimulated by stimulation signals, a sense region that receives sense signals corresponding to the stimulation signals. A grounded region can also be included, for example, between a sense region and a drive region. A shield layer can be formed of a substantially high resistance material and disposed to shield a sense region. A black mask line and conductive line under the black mask line can be included, for example, to provide low-resistance paths between a region of pixels and touch circuitry outside the touch screen borders.

摘要： A display may be provided with an active central region and a peripheral inactive region. The display may have one or more flexible edges in the peripheral inactive region. Conductive lines may pass between components in the active central region such as display pixels and touch sensor electrodes and components in the inactive peripheral region such as gate driver circuitry and patterned interconnect lines. Each conductive line may have an unbent segment on a portion of a display layer in the active central region and may have a segment on the bent edge of the display layer. The display layer may be formed from a polymer or other flexible material. The bent segments may be configured to be less susceptible to increases in resistance from bending than the unbent segments.

摘要： Embodiments of the present invention provide for a FFS TFT LCD with a high refresh rate without limiting the aperture of individual pixels. More specifically, embodiments of the invention provide for the use of common bus lines to reduce the effective resistance of the common electrode and to therefore allow for higher refresh rates of the display. Furthermore, the common bus lines can be positioned in such a manner so that they do not further reduce the aperture of the display. More specifically, the common bus lines can be positioned above or below existing elements of the display that are already opaque. Thus, adding the common bus lines need not reduce the aperture. The above can be achieved by, for example, placing the common bus lines above or below existing non-transparent lines, such as gate lines or data lines.

摘要翻译： 本发明的实施例提供了一种具有高刷新率的FFS TFT LCD，而不限制各个像素的孔径。 更具体地，本发明的实施例提供了使用公共总线线路来降低公共电极的有效电阻并因此允许显示器的更高刷新率。 此外，公共总线线路可以以这样的方式定位，使得它们不会进一步减小显示器的孔径。 更具体地，公共总线可以位于显示器的已经不透明的现有元件的上方或下方。 因此，添加公共总线不需要减小孔径。 上述可以通过例如将公共总线放置在现有的不透明线路之上或之下，例如栅极线或数据线来实现。
