    Abstract: A display may have a thin-film transistor layer formed from a layer of thin-film, transistor circuitry on a substrate. The thin-film transistor layer may overlap a color filter layer. A portion of the thin-film transistor layer may extend past the color filter layer to for a ledge region. Components such as a flexible printed circuit and a display driver integrated circuit may be mounted to the thin-film transistor layer in the ledge region. The components may have alignment marks. The thin-film transistor layer may have a black masking layer that is patterned to form openings for display pixels. In a border area of the display that overlaps the ledge region, the thin-film transistor layer may have alignment mark viewing windows. Alignment marks formed from black masking material in the windows may be aligned with respective alignment marks on the components.

    Abstract: A display may have a thin-film transistor (TFT) layer and a color filter layer. The TFT layer may have a first substrate, a first black masking layer, a planarization layer, and a layer of TFT circuitry on the planarization layer. The color filter layer may have a second substrate and a second black masking layer on the second substrate. A portion of the inactive area may serve as a logo area for displaying desired information to the user. A reflective structure may be formed on the bottom surface of the planarization layer, on the bottom surface of the first substrate, on the bottom surface of the second substrate, or on the upper surface of the first substrate in the logo area. In another embodiment, the logo area may be backlit by transmitting light through one or more openings in the first and second black masking layers in the logo area.

    Abstract: A liquid crystal display (LCD) includes an array of pixels over a thin film transistor (TFT) substrate. The TFT substrate includes a TFT that has a first metal layer to form a gate electrode and a second metal layer to form a source electrode and a drain electrode for each pixel. The LCD also includes an organic insulation layer disposed over the TFT substrate, where the organic insulator layer has trenches on a top surface. The LCD further includes a third metal layer disposed over the organic insulation layer in the trenches, the trenches having a trench depth at least equal to the thickness of the third metal layer. The LCD also includes a passivation layer over the third metal layer, and a pixel electrode for each pixel over the passivation layer. The LCD further includes a polymer layer over the pixel electrode, and liquid molecules on the polymer layer.

    Abstract: A display may have a color filter layer and a thin-film transistor layer. A layer of liquid crystal material may be located between the color filter layer and the thin-film transistor layer. Column spacers may be formed on the color filter layer to maintain a desired gap between the color filter and thin-film transistor layers. Support pads may be used to support the column spacers. Different column spacers may be located at different portions of the support pads to allow the support pad size to be reduced while ensuring adequate support. Lateral movement blocking structures such as circular rings may be used to prevent column spacer lateral movement. Subspacers located over pads may be used to create friction that retards lateral movement. Lateral movement may also be retarded by receiving column spacers in trenches or other recesses formed on a thin-film transistor layer.

    Abstract: A display may have pixels configured to display images. The pixels may be formed from thin-film transistor circuitry on a substrate. Color filter elements formed from colored polymer such as colored photoimageable polymer may be formed on the substrate. A black matrix formed from black photoimageable polymer may have an array of openings. The colored polymer may have first portions that overlap the black matrix and second portions in the openings that form the color filter elements. In some portions of the pixels, the thin-film transistor circuitry may be interposed between the first portions of the colored polymer and the black matrix. In other portions of the pixels, data lines may be formed that are overlapped by the black matrix and that are interposed between the first portions of the colored polymer and the black matrix.

    Abstract: 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.
