摘要： A display device and a method of testing the display device. The display device includes a substrate including both a display region on which pixel cells are located and a peripheral region; test pads, main pins connected to the pixel cells, and dummy pins that are respectively connected to the test pads, the test pads, the main pins, and the dummy pins being on the peripheral region of the substrate, and visual test lines on the peripheral region of the substrate. The visual test lines include a first portion connected to the main pins and a second portion connected to the test pads, and the first and second portions are disconnected from each other.

摘要： Embodiments may disclose a display device which includes a display panel including a display pixel displaying an image in response to a common voltage and a data voltage and a sensing pixel outputting a feedback voltage in response to the common voltage and a reference voltage; and a driving circuit unit supplying the data voltage and the reference voltage to the display pixel and the sensing pixel, respectively. The driving circuit unit includes a common voltage estimating part comparing the reference voltage and the feedback voltage to generate a counter signal having a counter value that is stepwise varied according to the comparing of the reference voltage and the feedback voltage; and a common voltage adjusting part stepwise varying the common voltage supplied to the display panel in response to the counter value.
