IMAGE DISPLAY SYSTEM AND METHOD OF DRIVING THE SAME

摘要

An image display system includes a camera part and an image display part. The image display part includes a user analyzer, a gamma corrector, a gamma voltage generator, and a display panel. The camera part takes a picture of a user and generates a user image signal. The user analyzer calculates the user's viewing direction based on the user image signal. The gamma corrector generates a correction gamma value based on the viewing direction. The gamma voltage generator generates a gamma voltage based on the correction gamma value, and the display panel displays an image corresponding to the gamma voltage. Accordingly, the image display system provides the image having an optimized gamma curve to the user in real time even without a separate input from the user.

1. An image display system comprising:
a camera part configured to take a picture of a user and configured to generate a user image signal; a user analyzer configured to receive the user image signal and configured to calculate a viewing direction and a viewing distance of the user based on the user image signal; a gamma corrector configured to generate a correction gamma value based on the viewing direction and the viewing distance; a gamma voltage generator configured to generate a gamma voltage based on the correction gamma value; a display panel configured to display an image corresponding to the gamma voltage; and a speaker module configured to output a sound synchronized with the image.
