ACTIVE MATRIX ORGANIC LIGHT EMITTING DIODE DISPLAY HAVING DETERIORATION DETECTION FUNCTION IN PROGRAMMING PERIOD
摘要:
There is provided an active matrix organic light emitting diode display including: a data driving unit converting previously prepared correction data into a correction signal and generates a driving signal according to the analog correction signal; a pixel unit having an organic light emitting diode (OLED) between first and second power supply terminals receiving first and second powers, respectively, charging a value corresponding to the correction data according to the driving signal in a predetermined programming period, detecting the driving signal in order to detect deterioration, and allowing current to flow through the OLED according to the value charged in the predetermined programming period in a predetermined holding period; and an ADC detecting deterioration voltage corresponding to the driving signal having deterioration information of the OLED of the pixel unit in the holding period.
