Abstract
(EN) The present invention relates to a technology for enabling a driving chip provided at an outer portion of an OLED panel to calculate and to compensate for the luminance deviations of pixel elements arranged in a display area through the use of a reference pixel provided at an adjacent location. The present invention comprises: a reference pixel element unit which is provided at an outer portion of a display area on an organic light emitting diode panel and operates corresponding to the pixel elements arranged in the display area; and a driving chip which is equipped in an area, in which the reference pixel element unit is included, of the outer portion of the display area, compares the luminance value of light incident from the reference pixel element unit with a reference luminance value, calculates a luminance deviation value according thereto, and controls the driving of the pixel elements arranged in the display area according to the luminance deviation value so that light, the luminance deviation of which has been compensated for, is irradiated.
(FR) La présente invention concerne une technologie pour permettre à une puce d'excitation prévue au niveau d'une partie extérieure d'un écran OLED de calculer et de compenser les écarts de luminance d'éléments pixels agencés dans une zone d'affichage grâce à l'utilisation d'un pixel de référence prévu dans un emplacement adjacent. La présente invention comprend : une unité élément pixel de référence qui est prévue dans une partie extérieure d'une zone d'affichage sur un panneau à diodes électroluminescentes organiques et fonctionne de façon correspondante aux éléments pixels agencés dans la zone d'affichage ; et une puce d'excitation qui est installée dans une zone, dans laquelle l'unité élément pixel de référence est incluse, de la partie extérieure de la zone d'affichage, compare la valeur de luminance value de la lumière incidente à partir de l'unité élément pixel de référence à une valeur de luminance de référence, calcule une valeur d'écart de luminance selon celle-ci, et commande l'excitation des éléments pixels agencés dans la zone d'affichage selon la valeur d'écart de luminance pour que la lumière, dont l'écart de luminance a été compensé, soit irradiée.
