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.

An electrode structure of a vanadium redox flow battery is disclosed, which includes a proton-exchange membrane, two graphite papers, two graphite felt units, two pads, two graphite polar plates, two metal plates and a lock-fixing device which are symmetrically stacked in sequence from center to outside. wherein each graphite polar plate has the flow channels with a grooved structure, and each graphite felt unit is embedded in the flow channels of one of the graphite polar plates, and then the graphite felt units are covered by the graphite papers such that the different electrolytes flow in their corresponding flow channels. The storage tanks of vanadium electrolyte are connected through the connection pipelines, and the redox reaction is performed through the flows of the vanadium electrolyte. The electrode structure of the vanadium redox flow battery can be stacked for forming a large-scale electrode structure to increase the electrical power.
