Abstract
Provided is an apparatus for measuring a picture and a lifetime of a display panel including: a chamber having at least one display panel for measurement disposed therein, and for uniformly maintaining temperature and humidity conditions of an inner portion; at least one camera installed in the chamber to obtain image signals of the display panel; a bias supply and measurement part for providing pulse bias voltage and current required to measure depending on control signals, and measuring the voltage and current to convert into digital data when the display panel is driven; a converter for converting the image signals obtained through the camera into digital data; and a control and data processing part for generating parameters by receiving the digital data from the bias supply and measurement part and the converter, and analyzing a lifetime of the display panel using the parameters.
