Test apparatus of display, method and computer readable medium

A test apparatus for a display device including a display unit including a plurality of pixels and a power source voltage application line respectively connected to a plurality of pixels and applying a power source voltage, the test apparatus comprising:

• an interface transmitting a characteristic information including resolution of the display unit and each equivalent model of a plurality of pixels, a reference voltage model including a plurality of reference voltages respectively corresponding to a plurality of pixels included in a unit region of the display unit, and pixel information including a position of a plurality of pixels to be tested among the plurality of pixels;
• a pixel model generator that schematizes the plurality of pixels into a plurality of test pixels and at least one equivalent load pixel according to the characteristic information and the pixel information to generate a pixel model;
• and
• a voltage mapper that maps the reference voltage model to the pixel model to calculate test voltages respectively corresponding to the plurality of test pixels and the equivalent load pixel.
