Abstract:
An organic light-emitting display includes: a pixel comprising a pixel circuit; a power supply configured to supply a first power voltage to the pixel circuit; a voltage divider configured to generate a power division voltage by dividing the first power voltage; a converter configured to generate a first digital value by performing an analog to digital (A/D) conversion of the power division voltage; a storage unit configured to store a first reference digital value generated by the converter, the first reference digital value corresponding to a first reference voltage and a second reference digital value generated by the converter, the second reference digital value corresponding to a second reference voltage that is different from the first reference voltage; and a voltage level determiner configured to determine a level of the first power voltage based on the first digital value, the first reference digital value, and the second reference digital value.
Abstract:
A method of calculating a gamma-value for a display panel includes displaying a first color test image having a first target gray-level and then measuring a first luminance-value implemented by at least one first color-pixel included in a jth display-area, displaying a second color test image having the first target gray-level and then measuring a second luminance-value implemented by at least one second color-pixel included in the jth display-area, deriving an estimated driving current flowing in the second color-pixel at the first target gray-level based on RGB gray level-driving current curves, deriving a second target gray-level when the estimated driving current flows in the first color-pixel based on the RGB gray level-driving current curves, and calculating a target gamma-value to be applied to the first color-pixel included in the jth display-area based on the first target gray-level, the second target gray-level, the first luminance-value, and the second luminance-value.

Abstract:
A electronic device includes a display panel including a first region in which a plurality of pixels and a second region having a higher transmittance than the first region, and an electronic module disposed under the display panel and overlapping the second region. The electronic module includes a camera module configured to image a subject to obtain a plurality of first images having a first resolution, an actuator configured to move the camera module while capturing each of the plurality of first images, and a processor configured to obtain a second image having a second resolution higher than the first resolution using the first images captured.
