ABSTRACT:
A driving method and an apparatus for a light emitting device have a simple configuration and activate the device at an accurate luminous intensity. The apparatus includes a power supply which outputs a function of time in synchronization with a timing pulse determining a lighting period, a k-multiplied timing pulse generating part which generates a timing pulse for a period multiplied by 1/k and a control information storing part which stores control information to decide which one of the generated n timing pulses is used. Appropriate pulses generated by said k-multiplied timing generating device are passed based on information stored in said control information storing device and the output from the power supply is sampled using the pulses passed, to activate the light emitting device.
