Abstract:
A test display panel is configured for application to a lighting test, and includes a plurality of reference voltage input terminals and a plurality of sub-pixels. The reference voltage input terminals are in a one-to-one correspondence to the sub-pixels. The display panel further includes a reference voltage supply circuit and a plurality of reference voltage lines. The sub-pixels include a plurality of first sub-pixels, second sub-pixels, and third sub-pixels having different colors. The reference voltage lines include a first reference voltage line, a second reference voltage line, and a third reference voltage line, each corresponding to respective sub-pixels. The reference voltage supply circuit is configured to provide reference voltages to the plurality of reference voltage lines in a time division manner. The reference voltage lines are electrically coupled to respective reference voltage input terminals of the sub-pixels.
