摘要： To provide a highly reliable lighting-emitting device that hardly causes defects in case a wiring board is bent, while realizing high brightness by increasing a mounting density of surface-mounted LEDs on a wiring board that is rounded into a truncated cone shape or a cylinder shape, the light-emitting device comprises: the wiring board, a plurality of sets of pads arranged in a line along a circumferential direction of the wiring board, and a plurality of surface-mounted LEDs respectively fixed to the pads. The device satisfies y≤−1.04x+1.80, where (L) is a length of the circumference of the wiring board with the pads, (y) (y=s/L) is a ratio of a total sum (s) of the lengths in the circumferential direction of the pads relative to the circumferential length (L), and (x) is a curvature of the wiring board where the pads are arranged.

摘要： An OLED driving device includes an overdrive controller (ODC) which executes an overdrive of applying to an OLED an electric current larger than a rated electric current for the OLED for a predetermined period (period for the overdrive) to cause the OLED to emit brighter light for the predetermined period than at the rated electric current for the OLED for light emitting. The controller (ODC) executes a PWM control to the electric current flowing to the OLED for the predetermined period, and sets a PWM signal in the predetermined period so that at least one pulse of a pulse before the OLED starts the light emitting and a pulse at a just time when the OLED starts the light emitting has a width larger than a width of a pulse after the OLED starts the light emitting.
