20110109240 | LIGHT-EMITTING ELEMENT DRIVE CIRCUIT SYSTEM, AND ELECTRONIC DEVICE - A light-emitting element drive circuit system for driving a light-emitting element includes a current circuit section that drives the light-emitting element at a preset drive current value, and a current value setting section. The current value setting section sets the drive current value so that the drive current value is changed during a preset transition period from a first current value to a second current value that is not equal to the first current value, and changed during a preset transition period from the second current value to a third current value that is not equal to both the first current value and the second current value. | 05-12-2011 |
20110109251 | LIGHT-EMITTING ELEMENT DRIVING CIRCUIT SYSTEM - A light-emitting element driving circuit system is provided in which a plurality of current paths, in each of which a light-emitting element and a switching element which is controlled to be switched ON and OFF for causing light to be emitted from the light-emitting element are connected in series, are placed in parallel to each other, wherein an ON time of each switching element is adjusted based on a light-emission period which is a period in which the light-emitting elements are caused to emit light in a circulating manner, such that a number of switching operations of each switching element is reduced. | 05-12-2011 |
