Abstract: A light emitting display device includes: a substrate; an organic film on the substrate; a green light emitting diode on the organic film and including a first anode; a red light emitting diode on the organic film and including a second anode; a black pixel defining film having an opening exposing the first anode and an opening exposing the second anode; a cathode on the black pixel defining film, the first anode, and the second anode; an encapsulation layer covering the cathode; a light blocking member on the encapsulation layer and having an opening; and a color filter filling the opening in the light blocking member. A portion of the organic film overlapping the first anode in a plan view has a halftone exposure area, and a step of the halftone exposure area is 30 nm or less.

Abstract: A method for evaluating a lifespan of an organic light emitting display panel includes: aging an organic light emitting display panel, including first light emitting elements for emitting a first color, second light emitting elements for emitting a second color, and third light emitting elements for emitting a third color, during a preset aging period by displaying the first color in a first pattern area of the organic light emitting display panel and displaying a fourth color in a second pattern area of the organic light emitting display panel; measuring luminances of the first pattern area and the second pattern area by displaying the first color in the first pattern area and the second pattern area during a measurement period; and calculating a lifespan of the first light emitting elements based on the measured luminance of the first pattern area and the measured luminance of the second pattern area.

Abstract: A display device includes: a display panel including pixels each having a light emitting element located between a first power source receiving a first power voltage and a second power line receiving a second power voltage, and photo sensors including a light receiving element located between a third power line receiving a reset voltage and the second power line; at least one temperature sensor for sensing a temperature of the display panel; a power supply for supplying the first power voltage, the second power voltage, and the reset voltage; and a controller connected to the temperature sensor and the power supply. The controller controls the power supply such that a voltage value of the reset voltage is changed based on the temperature of the display panel.

Abstract: A method for aging an organic light emitting display includes estimating a lifespan curve of a display panel based on at least one initial aging profile of the display panel, correcting at least one of a target luminance or a target white color coordinates of the display panel such that the estimated lifespan curve corresponds to a target lifespan curve, and setting a lifespan look up table by storing at least one of the correction value of the target luminance or the correction value of the target white color coordinates.
