Organic electroluminescent display and image correction method thereof
First Claim
1. An organic electroluminescent (EL) display, comprising:
- an image signal processor configured to receive an analog image signal from an external source and to convert the analog image signal to a digital image signal;
a brightness sensor configured to measure brightness of an external light and to convert the measured brightness into a brightness signal;
a wavelength sensor configured to measure wavelength of the external light and to convert the measured wavelength into a wavelength signal;
a data controller coupled electrically to the image signal processor, the brightness sensor, and the wavelength sensor, the data controller being configured to receive the digital image signal, the brightness signal, and the wavelength signal, and to generate a corrected image signal;
a data driver coupled electrically to the data controller; and
a display panel coupled electrically to the data driver, the display panel being configured to receive the corrected image signal from the data controller via the data driver and to display an image.

11. A method of correcting an image of an organic electroluminescent (EL) display, comprising:
-
converting measured brightness of an external light to a brightness signal; converting measured wavelength of the external light to a wavelength signal; obtaining correction data, the correction data proportionately related to the brightness and wavelength signals; applying the correction data to a received image signal to automatically form a corrected image signal; and outputting the corrected image signal to display an image. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
