Luminance control method and a display device using the same
First Claim
1. A method of establishing uniform luminance on a non-light-emitting display panel when display data are displayed on the non-light-emitting display panel with light being emitted from a light source toward the non-light-emitting display panel via a light guide plate, said method comprising:
- a storing step of storing correction values determined beforehand for making the luminance on the display panel substantially uniform; and
a correcting step of reading out one of the correction values corresponding to a position where the display data are displayed for correcting a gain of the display data, thereby making the luminance on the display panel substantially uniform.

Abstract
A display device includes a light source, a light guide plate diffusing light issuing from the light source and a non-light-emitting display panel illuminated with light being emitted from the light source via the light guide. The display device includes a storage for storing correction values determined beforehand for making the luminance on the display panel substantially uniform. The display device also includes a corrector for reading out one of the correction values corresponding to a position where display data are displayed from the storage and for correcting the gain of the display data for thereby making the luminance on the display panel substantially uniform.

9. A display device including a light source for emitting light, a light guide plate for guiding the light and a non-light-emitting display panel illuminated with the light guided by said light guide plate, said display device comprising:
-
a storage for storing correction values determined beforehand for making the luminance on the display panel substantially uniform; and
a corrector for reading out one of the correction values corresponding to a position where display data are displayed for correcting a gain of the display data to thereby make the luminance on the display panel substantially uniform. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
