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.

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 a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.

Abstract: A liquid crystal display may have main column spacers and subspacer column spacers. The column spacers may have cross shapes formed from overlapping perpendicular rectangular column spacer portions respectively located on a color filter layer and a thin-film transistor layer. The column spacers may have a hybrid configuration in which some of the rectangular portions on the thin- film transistor layer extend vertically and some extend horizontally. Column spacers may be formed from planarization layer material, may be formed from locally thickened portions of a planarization layer, and may have circular shapes.

Abstract: Liquid crystal display device (14) that has a color filter substrate (56) and a thin-film transistor substrate (58). A layer of liquid crystal material (52) is located between the color filter substrate (56) and the thin-film transistor substrate (58). Column spacers (122) are formed on the color filter substrate (56) to maintain a desired gap between the color filter substrate (56) and the thin-film transistor substrate (58). Support pads (130) used to support the column spacers (12) are formed on the thin-film transistor substrate (58). The column spacers (122) and support pads (130) have comparable thicknesses in order to avoid damage of surface layers of the substrates (56, 58) by scratching in case of misalignment between some of the column spacers (122) and support pads (130).

Abstract: A display may be provided with display layers. Ambient light reflections may be suppressed by forming antireflection coatings on one or more surfaces of the display layers. An antireflection coating may be formed by depositing alternating high and low index of refraction dielectric layers using a sputtering tool. A controller may control the operation of a spectrometer and the sputtering tool. To ensure that the antireflection coating exhibits a desired color, the controller may direct the sputtering tool or other equipment to deposit a subset of the dielectric layers for the antireflection coating. A spectrum may then be measured with the spectrometer. Based on the measured light spectrum, thickness adjustments or other adjustments may be made to remaining dielectric layers to ensure that the antireflection coating color matches a target color.

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. The column spacer structures may be formed from polymer structures such as photoresist pillars and may include metal pads. The metal pads may be formed on the upper surface of the thin-film transistor layer or the lower surface of the color filter layer. The photoresist pillars may be formed on a surface in the display such as the lower surface of the color filter layer. Column spacer structures may include main spacer structures, subspacer structures, and intermediate thickness spacer structures to enhance pooling mura and light leakage performance.

Abstract: Display layers in an electronic device may be used to generate images. The display layers may include liquid crystal display layers such as upper and lower polarizers and a layer of liquid crystal material. A display cover layer may be mounted in a housing using adhesive. A touch sensor layer may be mounted under the display cover layer. An air gap may separate the upper polarizer from the touch sensor layer and display cover layer. Antireflection coatings may be formed on the lower surface of the display cover layer or touch sensor layer and may be formed on the upper surface of the upper polarizer. The antireflection coatings may include coatings formed from a polymer hard coat covered with a polymer layer having a different index of refraction and may include broadband antireflection coating material formed from textured polymer or other structure exhibiting a continuously varying index of refraction.
