Abstract
Official abstract text for this publication.
A pixel structure, a display device, and a method of manufacturing a pixel structure, the pixel structure including a base substrate; at least one first electrode arranged in an upper portion of the base substrate; at least one second electrode having a circular shape extending along a circumferential direction around the at least one first electrode; and a plurality of LED elements connected to the first and second electrodes.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a pixel structure, the method comprising: applying a plurality of LED elements and a solvent on a plurality of circularly shaped first electrodes and a plurality of annularly shaped second electrodes respectively extending along a circumferential direction around the first electrodes; and respectively applying different voltages to the first electrodes and the second electrodes, wherein the LED elements are aligned between corresponding ones of the first electrodes and the second electrodes, wherein two of the second electrodes are connected by an electrode line at a same layer as the second electrodes. 2. The method as claimed in claim 1 , wherein a separation distance between the corresponding ones of the first electrodes and the second electrodes is about 1 μm to about 7 μm, and wherein a difference between voltages respectively applied to the first electrodes and the second electrodes is about 10 V to about 50 V. 3. The method as claimed in claim 1 , wherein applying the different voltages to the first electrodes and the second electrodes comprises radially generating a first electric field around the first electrodes and between respective ones of the first electrodes and the second electrodes. 4. The method as claimed in claim 1 , wherein a same voltage is applied to each of the first electrodes, and wherein a same voltage is applied to each of the second electrodes.
