Power control method of light emitting device for image display, light emitting device for image display, display device and television receiver

摘要

In a method of controlling power of a light emitting device for image display that irradiates illumination light from divided regions, light emission brightness data of each light emitting element of the light emitting device is determined based on image data for image display (S20). Power in each region and total light emission power are computed based on the light emission brightness data of each light emitting element for each region (S40). If the computed total light emission power exceeds predetermined allowable power, the power in each region is limited so that the total light emission power is equal to or less than the predetermined allowable power (S50).
