摘要

PROBLEM TO BE SOLVED: To suppress a reduction in image quality.SOLUTION: There is provided a lighting unit that includes: a light source; a time-division control part that performs a time division operation on a value represented by a first brightness control signal of a first bit number for controlling the brightness of the light source by a second brightness control signal with a second bit number smaller than the first bit number, so as to create a third brightness control signal with a pulse width corresponding to a value represented by the second brightness control signal; and a driving part that creates a driving signal for causing the light source to emit light on the basis of the third brightness control signal and supplies the driving signal to the light source. Also provided is a display device.
