Abstract: An apparatus for manufacturing a display device includes a chamber in which a display substrate is arranged, a lamp portion arranged outside or inside the chamber irradiating light, and a mask arranged inside the chamber to expose a portion of the display substrate and to shield another portion of the display substrate. The mast includes a hole through which the light irradiated from the lamp portion passes, and the lamp portion includes a flash lamp or a xenon lamp.

Abstract: A method of determining whether a display manufacturing facility is abnormal includes a first step of obtaining facility information data of facilities used to manufacture a display panel, a second step of preparing a display module by attaching a printed circuit board and a driving chip to the display panel, a third step of obtaining preliminary inspection data through an on-off test on the display module, a fourth step of associating the facility information data with the preliminary inspection data, establishing a database by repeatedly performing the first step to the fourth step, obtaining real-time inspection data through an on-off test on a display module to be inspected, determining whether the display module to be inspected is normal, and determining a facility causing abnormality of the display module, from the real-time inspection data by using the database, in case that the display module to be inspected is abnormal is determined.

Abstract: An apparatus to determine a driving voltage includes: a color coordinate value comparator to measure a color coordinate value of an organic light-emitting display apparatus, to calculate a difference value between the measured color coordinate value and a fiducial color coordinate value, and to compare the calculated difference value with a first critical value; a voltage level changer to increase an absolute value of a driving voltage applied to each pixel of the organic light-emitting display apparatus when the difference value is greater than or equal to the first critical value; and a voltage level determiner to determine a level of the driving voltage at a point of time when the difference value is calculated as a final level of a driving voltage, when the difference value is less than the first critical value.
