Abstract: A display may have an array of pixels arranged in rows and columns. Display driver circuitry may be provided along an edge of the display. Data lines that are associated with columns of the pixels may be used to distribute data from the display driver circuitry to the pixels. Gate lines in the display may each have a horizontal straight portion that extends along a respective row of the pixels and may each have one or more non-horizontal segments such as zigzag segments. The non-horizontal portion of each gate line may be connected to the horizontal straight portion of the gate line by a via. The non-horizontal portions may each have portions that are overlapped by portions of the data lines. Dummy gate line structures may be provided on the display that are not coupled to any of the pixels in the display.

Abstract: An electronic device may have a flexible display. The display may have portions that are bent along a bend axis. The display may have display circuitry such as an array of display pixels in an active area and signal lines, thin-film transistor support circuitry and other display circuitry in an inactive area of the display surrounding the active area. The display circuitry may be formed on a substrate such as a flexible polymer substrate. The flexible polymer substrate may be formed by depositing polymer on a support structure that has raised portions. The raised portions may create locally thinned regions in the flexible polymer substrate. The reduced thickness of the flexible polymer substrate in the thinned regions may help ensure that a neutral stress plane that is associated with bending the display along the bend axis is aligned with the display circuitry, thereby minimizing stress in the display circuitry.

Abstract: A display may have a liquid crystal layer sandwiched between a thin-film transistor layer and a color filter layer. An upper polarizer may be placed on top of the thin-film transistor layer. A lower polarizer may be placed under the color filter layer. Components may be bonded to bond pads on the inner surface of the thin-film transistor layer using anisotropic conductive film. Bond quality may be assessed by probing probe pads that are coupled to the bond pads or by visually inspecting the bond pads through the thin-film transistor layer. Opaque masking material in the inactive area may be provided with openings to accommodate the bond pads. Additional opaque masking material may be placed on the underside of the upper polarizer and on the upper surface of the thin-film transistor layer to block the openings from view following visual inspection.

Abstract: A display may have a thin-film transistor (TFT) layer and color filter layer. Light blocking structures in an inactive area of the display may prevent stray backlight from leaking out of the display. The thin-film transistor 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. Light-cured sealant may be formed between the TFT layer and the color filter layer. Gaps may be formed in the second black masking layer to allow light to cure the sealant. At least a portion of the TFT circuitry may serve to block stray backlight penetrating through the gaps in the second black masking layer during normal operation of the display.

Abstract: A display may have a thin-film transistor layer and a color filter layer. The display may include light blocking structures formed on a transparent substrate. In one arrangement, a clear planarization layer may be formed over the light blocking structures. The thin-film transistor layer may be formed over the planarization layer. The color filter layer may be integrated with the thin-film transistor layer. At least light blocking structures and the planarization layer should be formed from high temperature resistance material. In another arrangement, the color filter layer may be formed on the light blocking structures. A clear planarization layer may then be formed over the color filter layer. The thin-film transistor layer may be formed on the planarization layer. In this arrangement, the color filter layer also needs to be formed from thermal resistance material.

Abstract: A thin-film transistor having a protection layer for a planarization layer. The protection layer prevents reduction of the planarization layer during an ashing process, thereby preventing the formation of a steeply tapered via hole through the planarization layer. In this manner, the via hole may be coated with a conductive element that may serve as a conductive path between a common electrode and the drain of the transistor.
