ABSTRACT:
An image display apparatus and method are provided. The image display apparatus includes an external light detection module which detects an intensity of external illumination; a storage module which stores a plurality of light emitting unit control values; and a control module which selectively performs, according to a result of a determination, a lightness compensation operation for compensating a lightness of a light emitting unit and a visibility adjustment operation for adjusting the visibility of the original input image. The method includes detecting an intensity of external illumination; determining whether a visibility of an original input image can be ensured according to an input light emitting control value and the detected external illumination intensity; and selectively performing, according to the determination, a lightness compensation operation for compensating a lightness of a light emitting unit and a visibility adjustment operation for adjusting the visibility of the original input image.
