<P>PROBLEM TO BE SOLVED: To make a user grasp the residual amount of a battery stepwise according to the residual amount of a battery without abruptly turning off the power source of an information display device, and also to prolong the driving time after the residual amount of the battery becomes small by switching to power-saving display mode while suppressing the power consumption when the residual amount of the battery becomes small. <P>SOLUTION: The method for driving the spontaneous light emission type display is characterized in that at least two or more set reference values for the residual amount of the battery driving a battery driven type information display device equipped with the spontaneous light emission type display such as an organic EL display, are disposed to judge the residual amount of the battery level by comparing a detected value of the residual amount of the battery with the set values in magnitude, and a thinned-out display mode is entered by switching to a driving signal for thinning out and turning off the pixels of the spontaneous light emission display or pixels of R (red), G (green), and B (blue) stepwise as the residual amount of the battery level drops. <P>COPYRIGHT: (C)2007,JPO&INPIT |
