Abstract
A display device includes: light-emitting elements in a backlight divided into a plurality of areas, the light-emitting elements being arranged in such a manner as to correspond to the plurality of areas; and a drive unit configured to drive the light-emitting elements in the plurality of areas by time division based on an input image every prescribed period of time, the drive unit turning on all the light-emitting elements in the plurality of areas in a partial period of the prescribed period of time and driving those light-emitting elements in at least one of the plurality of areas based on the input image in a remaining period of the prescribed period of time.
Claims6
A display device comprising:
- light-emitting elements in a backlight divided into a plurality of areas, the light-emitting elements being arranged in a plurality of rows and a plurality of columns in such a manner as to correspond to the plurality of areas;
- a plurality of switches configured to control ON/OFF of voltage application for each row of the light-emitting elements;
- and
- a drive unit configured to drive the light-emitting elements in the plurality of areas by time division based on an input image every prescribed period of time by sequentially driving the light emitting-elements in at least one row in each of the prescribed periods into which a frame period is divided, the drive unit turning on all the light-emitting elements in the plurality of areas by turning on all of the plurality of switches in a partial period of the prescribed period of time and driving those light-emitting elements in at least one of the plurality of areas based on the input image by turning on a part of the plurality of switches and turning off the other part of the plurality of switches in a remaining period of the prescribed period of time.
