摘要： A light emitting element drive apparatus that drives light emitting elements reduces power loss caused by variability between forward voltage drops of the light emitting elements. A plurality of voltage applying sections (1, 32 and 33; and 2, 34 and 35) generate application voltages based on a detection voltage determined based on a maximum forward voltage drop among the forward voltage drops of the light emitting element arrays (11 to 14), and apply the generated application voltages to the light emitting elements (11 to 14). Switching sections (30 and 31) switch between a plurality of voltage applying sections (1, 32 and 33; and 2, 34 and 35) to which the light emitting element arrays (11 to 14) individually connect. Controlling sections (40 to 42) control the switching sections (30 and 31) to switch connection to minimize the difference between forward voltage drops of light emitting element arrays (11 to 14).

An LED backlight (121) has a light emitting surface in which P light emitting areas that can each individually emit light are divided into Q groups, and radiates light from the P light emitting areas to a display panel (110). A feature amount detecting section (133) detects a feature amount of an image signal. A brightness calculating section (132) determines the light emission values of the P light emitting areas on a per light emitting area basis based on the feature amounts detected.A backlight driving section (122) detects the light emitting states in the P light emitting areas on a per group basis based on the light emitting brightness values determined. The backlight driving section (122) changes the group in which the light emitting state is renewed, among the Q groups at a frequency of M times per one frame period of the image signal.
