    Abstract: A display may have a layer of liquid crystal material between a color filter layer and a thin-film transistor layer. Column spacer structures may be formed between the color filter layer and the thin-film transistor layer to maintain a desired separation between the color filter and thin-film transistor layers. Column spacers may be deposited in column spacer regions of the color filter layer. The color filter layer may include rows of red, green, and blue color filter elements. Blue color filter material that forms blue color filter elements in the color filter layer may also be used to form a planar surface over red and green color filter elements in the column spacer regions. Using the blue color filter material to planarize the surface on which column spacers are formed ensures that the column spacers provide sufficient support for the display without requiring an additional planarization layer.

    Abstract: A display may have a thin-film transistor layer formed from a layer of thin-film transistor circuitry on a substrate, a color filter layer, and a layer of liquid crystal material interposed between the thin-film transistor layer and the color filter layer. The thin-film transistor layer, the liquid crystal layer, and the color filter layer may be sandwiched between upper and lower polarizers. A backlight unit may supply backlight illumination for pixels in the display. The color filter layer may have a black matrix with an array of openings. Color filter elements of different colors may be formed in the openings. The black matrix may have sidewalls that are steep or that are undercut. The profile of the black matrix helps block improperly colored off-axis light and thereby reduces undesired color mixing in the display.

The display pixels may be organic light-emitting diode display pixels or display pixels in a liquid crystal display. In an organic light-emitting diode display, hybrid thin-film transistor structures may be formed that include semiconducting oxide thin-film transistors, silicon thin-film transistors, and capacitor structures. The capacitor structures may overlap the semiconducting oxide thin-film transistors. Organic light-emitting diode display pixels may have combinations of oxide and silicon transistors. In a liquid crystal display, display driver circuitry may include silicon thin-film transistor circuitry and display pixels may be based on oxide thin-film transistors. A single layer or two different layers of gate metal may be used in forming silicon transistor gates and oxide transistor gates. A silicon transistor may have a gate that overlaps a floating gate structure.

    Abstract: A method is provided for fabricating thin-film transistors (TFTs) for an LCD having an array of pixels. The method includes depositing a first photoresist layer over a portion of a TFT stack. The TFT stack includes a conductive gate layer, and a semiconductor layer. The method also includes doping the exposed semiconductor layer with a first doping dose. The method further includes etching a portion of the conductive gate layer to expose a portion of the semiconductor layer, and doping the exposed portion of the semiconductor layer with a second doping dose. The method also includes removing the first photoresist layer, and depositing a second photoresist layer over a first portion of the doped semiconductor layer in an active area of the pixels to expose a second portion of the doped semiconductor layer in an area surrounding the active area. The method further includes doping the second portion of the doped semiconductor layer with a third doping dose, the first dose being higher than the second dose and the third dose.

    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 (TFT) layer. The TFT layer may include thin-film transistors formed on top of a glass substrate. A passivation layer may be formed on the thin-film transistor layers. A first low-k dielectric layer may be formed on the passivation layer. Data line routing structures may be formed on the first low-k dielectric layer. A second low-k dielectric layer may be formed on the first low-k dielectric layer. A common voltage electrode and associated storage capacitance may be formed on the second low-k dielectric layer. The first and second low-k dielectric layers may be formed from material having substantially similar refractive indices to maximize backlight transmittance and may have appropriate thicknesses so as to minimize parasitic capacitive loading.
