Abstract
Provided are a pixel having two contacting points and an operating method of the pixel. The pixel includes a positive power terminal and a negative power terminal which are related to power required for driving of a pixel driving circuit unit driving a plurality of light-emitting elements, wherein the positive power terminal is connected to a data driving circuit, and the negative power terminal is connected to a scan driving circuit. The pixel may be driven according to a potential difference between a signal output from the data driving circuit and a signal output from the scan driving circuit.
