BACKLIGHT, CONTROL METHOD THEREOF, LIQUID CRYSTAL DISPLAY DEVICE AND ELECTRONIC DEVICE

摘要

<P>PROBLEM TO BE SOLVED: To easily avoid a phenomenon that a screen end portion becomes darker than the screen center when successively emitting light from a plurality of light emitting areas, in a backlight for irradiating a liquid crystal display panel with light. Ž<P>SOLUTION: A light source driving circuit is configured to successively turn on first to sixth-area light sources with a luminance of 100%. The first-area light source positioned at the uppermost end of the screen is turned on with a luminance of 60% at the timing before the timing of turning on with a luminance of 100%, and also, the first-area light source is turned on with a luminance of 20% before the timing. The sixth-area light source positioned at the downmost end of the screen is turned on with a luminance of 60% after the timing of turning on with a luminance of 100%, further, the sixth-area light source is turned on with a luminance of 20% at the timing after the subsequent timing.
