    摘要: A display may have an array of pixels controlled by display driver circuitry. The pixels may have pixel circuits. In liquid crystal display configurations, each pixel circuit may have an electrode that applies electric fields to an associated portion of a liquid crystal layer. In organic light-emitting diode displays, each pixel circuit may have a drive transistor that applies current to an organic light-emitting diode in the pixel circuit. The pixel circuits and display driver circuitry may have thin-film transistor circuitry that includes transistor such as silicon transistors and semiconducting-oxide transistors. Semiconducting-oxide transistors and silicon transistors may be formed on a common substrate. Semiconducting-oxide transistors may have polysilicon layers with doped regions that serve as gates. Semiconducting-oxide channel regions overlap the gates. Transparent conductive oxide and metal may be used to form source-drain terminals that are coupled to opposing edges of the semiconducting oxide channel regions.

    摘要: A display may have a thin-film transistor layer and color filter layer. The display may have an active area and an inactive border area. Light blocking structures in the inactive area may prevent stray backlight from a backlight light guide plate from leaking out of the display. The thin-film transistor layer may have a clear substrate, a patterned black masking layer on the clear substrate, a clear planarization layer on the black masking layer, and a layer of thin-film transistor circuitry on the clear planarization layer. The black masking layer may be formed from black photoimageable polyimide. The clear planarization layer may be formed from spin-on glass. The light blocking structures may include a first layer formed from a portion of the black masking layer and a second layer such as a layer of black tape on the underside of the color filter layer.

    摘要: A touch screen having layers. The touch screen can include a substrate upon which the layers of the touch screen are disposed, and a touch region including a touch pixel electrode, a first display sub-pixel and a second display sub-pixel. The touch screen can also include a sense connection coupled to touch sensing circuitry. An intermediate connection can be disposed between the touch pixel electrode and the sense connection, and can be coupled to the sense connection at the first display sub-pixel and the touch pixel electrode at the second display sub-pixel. In some examples, the sense connection can be disposed at least partially underneath a structure in the first display sub-pixel, such as a data line. In some examples, the intermediate connection can be comprised of a same material type as a structure in the first display sub-pixel, such as a gate line material.
