ORGANIC LIGHT EMITTING DIODE DISPLAY PANEL AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE

摘要

An organic light-emitting diode display panel and an OLED display device have a sensing driving stabilizer that can increase accuracy in sensing and compensation by providing potential stability to a reference voltage line acting as a sensing line during the sensing driving.
