Backlight device and display apparatus |
摘要 |
Provided is a backlight device wherein when the drive duty and the drive current are controlled according to a motion, the image quality is improved by preventing flicker caused by the change of the drive waveform. A light-emitting unit (121) comprises a plurality of light-emitting areas. A motion amount detecting unit (131) detects the motion amount of an image in each of a plurality of motion areas each corresponding to at least one or more light-emitting areas. A drive condition specifying unit specifies a drive condition including the duty and pulse height value of a drive pulse for causing each of the plurality of light-emitting areas to emit light, on the basis of the detected motion amount. A drive unit drives each of the plurality of light-emitting areas according to the specified drive condition. The drive condition specifying unit adjusts the drive condition such that the drive condition temporally smoothly changes.
