Abstract: A display may have organic light-emitting diode pixels formed from thin-film circuitry. The thin-film circuitry may be formed in thin-film transistor (TFT) layers and the organic light-emitting diodes may include anodes and cathodes and an organic emissive layer formed over the TFT layers between the anodes and cathodes. The organic emissive layer may be formed via chemical evaporation techniques. The display may include moisture blocking structures such as organic emissive layer disconnecting structures that introduce one or more gaps in the organic emissive layer during evaporation so that any potential moisture permeating path from the display panel edge to the active area of the display is completely terminated.

Abstract: An electronic device may have a display such as an organic light-emitting diode display. The 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. A first passivation layer, a first planarization layer, and a second passivation layer may be formed over the cathode. The first and second passivation layers may be formed from inorganic material. A second planarization layer may be formed over the second passivation layer between the second passivation layer and a polarizer. The second planarization layer may planarize the polarizer at the edges of the active area of the display where the polarizer would otherwise have a steep taper. Planarizing the polarizer in this way mitigates undesirable secondary reflections off of the polarizer. The first and second planarization layers may be formed from organic material.

Abstract: An organic light-emitting diode (OLED) display may have an array of pixels that each have OLED layers interposed between a cathode and an anode. The display may also include a planarization layer that is deposited using inkjet printing. To mitigate the need for dam structures to prevent overflow of the planarization layer during inkjet printing, capillary-flow-inducing structures may be included in the inactive area of the display. The topology of the capillary-flow-inducing structures may be propagated to a passivation layer such that an upper surface of the passivation layer has a similar topology as the capillary-flow-inducing structures. The planarization layer therefore undergoes capillary flow when deposited on the upper surface of the passivation layer. The capillary-flow-inducing structures may be formed from dots, rectangular strips, or trapezoidal strips. The capillary-flow-inducing structures may be formed from the same material as spacers in the active area or using another layer in the display.
