DISPLAY PANEL AND TEST METHOD THEREOF

A method of testing a display panel includes applying a test voltage to each of data lines; applying a gate signal to each of the gate lines; measuring a sensing voltage applied to end of the light emitting unit of each of the pixels by the pixel circuit in response to the gate signal and the test v...

Zusammenfassung:	A method of testing a display panel includes applying a test voltage to each of data lines; applying a gate signal to each of the gate lines; measuring a sensing voltage applied to end of the light emitting unit of each of the pixels by the pixel circuit in response to the gate signal and the test voltage; and determining whether the light emitting elements are validly connected in series within the light emitting unit of each of the pixels based on the sensing voltage.
