Abstract: An electronic device may include a display and an optical sensor formed underneath the display. A pixel removal region on the display may at least partially overlap with the sensor. The pixel removal region may include a plurality of non-pixel regions each of which is devoid of thin-film transistors. The plurality of non-pixel regions is configured to increase the transmittance of light through the display to the sensor. In addition to removing thin-film transistors in the pixel removal region, additional layers in the display stack-up may be removed. In particular, a cathode layer, polyimide layer, and/or substrate in the display stack-up may be patterned to have an opening in the pixel removal region. A polarizer may be bleached in the pixel removal region for additional transmittance gains. The cathode layer may be removed using laser ablation with a spot laser or blanket illumination.

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 display may have an array of pixels with light-emitting diodes that emit light to form images. The display may have a substrate with thin-film transistor circuitry for supplying signals to the light-emitting diodes. Anodes may be formed on the thin-film transistor circuitry, emissive material may be formed on the anodes, and a cathode layer may overlap the anodes. During operation, currents may flow between the anodes and the cathode layer to illuminate the diodes. An array of electrical components such as an array of light sensors in an integrated circuit may be mounted under the substrate. An array of corresponding light transmitting windows may be formed in the display each of which may allow light to pass through the display to a corresponding one of the light sensors. Light transmitting windows may be formed by patterning the cathode layer and supplying the windows with antireflection layers.

Abstract: A display may have an array of pixels formed from organic light-emitting diodes of different colors. Each organic light-emitting diode may have an anode, a cathode, and an emissive layer between the anode and cathode. To prevent undesired color shifts with off-axis viewing angles, evaporated color filters may be formed on the cathode in alignment with the light-emitting diodes. The color filters may include red color filters that overlap the red diodes but not the green and blue diodes, may include red, blue, and green filters that overlap respective red, green, and blue diodes, or may include an orange filter that overlaps red and green diodes and a blue filter that overlaps blue diodes. The color filters may serve as a capping layer for the diodes or a capping layer that is separate from the color filters can be incorporated into the display.

Abstract: A display may have a stretchable portion with hermetically sealed rigid pixel islands. A flexible interconnect region may be interposed between the hermetically sealed rigid pixel islands. The hermetically sealed rigid pixel islands may include organic light-emitting diode (OLED) pixels. A conductive cutting structure may have an undercut that causes a discontinuity in a conductive OLED layer to mitigate lateral leakage. The conductive cutting structure may also be electrically connected to a cathode for the OLED pixels and provide a cathode voltage to the cathode. First and second inorganic passivation layers may be formed over the OLED pixels. Multiple discrete portions of an organic inkjet printed layer may be interposed between the first and second inorganic passivation layers.

Abstract: An electronic device may have a support structure that supports a display and lenses. Each lens may be a reflective lens such as a catadioptric lens that receives polarized image light from the display and provides a corresponding image to an eye box. The display may be an emissive display with pixels that include light-emitting diodes. The light-emitting diodes may be overlapped by a light recycling layer such as a reflective polarizer or cholesteric liquid crystal layer. The light recycling layer recycles emitted light to enhance display efficiency.
