Abstract

PURPOSE: To prolong the service life of a fluorescent lamp by supplying luminance data so that there is not a fluorescent lamp which turns off completely when respective fluorescent lamps constituting the display device display an image. CONSTITUTION: A display panel 1 is constituted by arraying the fluorescent lamps in matrix. Display addresses indicating the individual fluorescent lamps and their luminance data are inputted to a ROM 2. The ROM 2 gives specific luminance, e.g. 1/256 of 256 gradations to the inputted luminance data and adds the luminance data thereto. With the output of the ROM 2, fluorescent lamps displayed with display addresses are turned on according to the said addition data.. Consequently, there is no fluorescent lamp which turns off and the service life of the fluorescent lamps can greatly be prolonged.
