Display apparatus, light source driving apparatus and driving method thereof

摘要

Disclosed are a display apparatus, a light source driving apparatus and a driving method thereof, the display apparatus including: an image processor which is configured to process an image; and a controller which is configured to set a plurality of current levels corresponding to a plurality of screen modes for a display and control the display to perform a dimming by receiving a current level of a current which corresponds to a screen mode of the display.

主权项

1. A display apparatus comprising:
an image processor which is configured to process an image comprising a plurality of frames; and a driver which is configured to drive a light source, the driver comprising a multiplexer and a constant current controller; a controller which is configured:
to set a plurality of current levels corresponding to a plurality of screen modes for a display,in response to a screen mode among the plurality of screen modes, to control the multiplexes to select a reference current having a current level corresponding to the screen mode and to output the selected reference current to the constant current controller, andto control the constant current controller to supply the light source with a driving current having the current level corresponding to the screen mode based on the selected reference current output from the multiplexer by changing an on/off ratio of the current level to perform a dimming for each of the plurality of frames.
