Electronic illuminating device
View Patent ↗An electronic illuminating device includes an illuminating area, a routing area and a control area. The illuminating area includes multiple light-emitting blocks and multiple illuminating area power-supply lines. Each the light-emitting block employs at least one light-emitting element as light source, and further is electrically coupled to a corresponding one of the illuminating area power-supply lines. The routing area includes multiple routing area power-supply lines, and each the routing area power-supply line is electrically coupled to a corresponding one of the illuminating area power-supply lines. The control area provides powers to the routing area power-supply lines. A width of at least one of the illuminating area power-supply lines and the corresponding routing area power-supply line or a length of at least one of the routing area power-supply lines is adjusted, such that differences among resistances between the light-emitting blocks and the control area are within 20%.
