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 method is provided for fabricating a back channel etching (BCE) oxide thin film transistor (TFT) for a liquid crystal display. The method includes forming a first metal layer having a first portion and a second portion over a substrate, depositing a gate insulator over the first metal layer, and disposing a semiconductor layer over the gate insulator. The method also includes depositing a half-tone photoresist to cover a first portion of the semiconductor layer and the first portion of the first metal layer. The half-tone photoresist has a first portion and a second portion thicker than the first portion. The first portion has a via hole above the second portion of the first metal layer. The second portion of the half-tone photoresist covers the first portion of the first metal layer. The method further includes etching a portion of the gate insulator through the via hole such that the second portion of the first metal layer is exposed, removing the first portion of the half-tone photoresist while remaining the second portion of the half-tone photoresist, and etching to remove a second portion of the semiconductor layer that is not covered by the half-tone photoresist.

Abstract: Systems and methods may reduce or eliminate image artifacts due to a defective pixel of an electronic display. An electronic display may include pixels that respectively include a self-emissive element, pixel drive circuitry that supplies a pixel drive current to drive the self-emissive element, and signal routing circuitry that reduces or eliminates a visual artifact due to a defective pixel among the pixels. The signal routing circuitry may do this by turning off the self-emissive element, supplying image data from the pixel drive circuitry to a first adjacent pixel, or receiving image data from other pixel drive circuitry from the first adjacent pixel or a second adjacent pixel.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.

Abstract: An electronic display may include an active area having a first pixel formed in the active area, where the first pixel emits light in response to image data. The electronic display may also include a controller to transmit the image data to the first pixel. The first pixel may include an organic light-emitting diode that emits the light in response to the image data, memory to digitally store the image data received from the controller, and driver circuitry to receive the image data from the memory. The driver circuitry may cause the organic light-emitting diode to emit the light in response to the image data.

Abstract: An electronic device may have a display. A gaze detection system may gather information on a user's point of gaze on the display. Based on the point-of-gaze information, control circuitry in the electronic device may produce image data for an image with areas of different resolutions. A full-resolution portion of the image may overlap the point of gaze. Lower resolution portions of the image may surround the full-resolution portion. The display may have a pixel array. The pixel array may include rows and columns of pixels. Data lines may be used to supply data to the columns of pixels in accordance with row selection signals supplied to the rows of pixels. Display driver circuitry may be used to display the image using the pixel array. The display driver circuitry may have row selection circuitry and column expander circuitry that are responsive to a resolution mode selection signal.
