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: 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 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 thin-film transistor circuitry on a substrate with a substrate surface. An array of organic light-emitting diodes may be formed on the thin-film transistor circuitry. The organic light-emitting diodes may have anodes, cathodes, and emissive material located between the anodes and cathodes. The anodes may be oriented so that they are not parallel to the substrate surface. The anodes may have curved shapes or may have tilted shapes. Tilted anodes may have multiple segments. Anodes may be tilted by amounts that vary as a function of lateral distance across a display.
Abstract translation: 显示器可以在具有衬底表面的衬底上具有薄膜晶体管电路。 可以在薄膜晶体管电路上形成有机发光二极管阵列。 有机发光二极管可以具有位于阳极和阴极之间的阳极，阴极和发光材料。 阳极可以被定向成使得它们不平行于衬底表面。 阳极可以具有弯曲形状或者可以具有倾斜形状。 倾斜阳极可能有多个部分。 阳极可能会随着显示器横向距离的变化而变化。
