Patent ID: 11017727

Abstract:
A driving voltage setting device includes a first voltage determiner, a luminance measurer, and a second voltage determiner. The first voltage determiner is configured to: determine, based on a variable preliminary black gray scale voltage (BGSV) under a first display luminance condition, a first BGSV corresponding to a first display luminance of a display device; and determine, based on the variable preliminary BGSV under a second display luminance condition, a second BGSV corresponding to a second display luminance of the display device. The luminance measurer is configured to measure a luminance of a BGSV of the display device using the variable preliminary BGSV. The second voltage determiner is configured to determine, based on the first BGSV and the second BGSV, BGSVs respectively corresponding to a plurality of preset display luminances between the first display luminance and the second display luminance.
