Abstract:
Embodiments of the present disclosure provide a display device and a method of driving the display device. The display device includes: a side-lighting backlight source, a display panel disposed at a light exit side of the side-lighting backlight source, and a light controlling component disposed between the display panel and the side-lighting backlight source; the side-lighting backlight source comprises a light guide plate and a plurality of light emitting devices disposed at a side of the light guide plate; the light guide plate includes a plurality of first regions and a brightness of a light emitting face of each of the first regions is controllable by at least one of the light emitting devices; the light controlling component includes a plurality of second regions configured such that one of the first regions covers at least one of the second regions; the brightness of the light emitting face of each of the first regions and a light transmittance of each of the second regions are controlled according to the contrast of the image to be displayed by a corresponding region of the liquid crystal display panel.

Claim (Index 10):
The display device according to  claim 1 , further comprising:\n control circuits being in one-to-one correspondance to and in electrical connection with the side-lighting backlight source, the display panel and the light controlling component; and a processor electrically connected to the control circuits; wherein, the processor is configured to acquire a contrast of an image being currently displayed and a contrast of an image to be displayed by the display panel through the control circuits electrically connected to the display panel, determine the brightness of the light emitting face required for respective first region of the side-lighting backlight source and light transmittances required for respective second regions of the light controlling component according to the contrast of the image being currently displayed and the contrast of the image to be displayed, and modulate the brightness of the light emitting face of the respective first region by using the control circuit electrically connected to the side-lighting backlight source and the light transmittances of the respective second regions by the control circuit electrically connected to the light controlling component, such that the light coming from the side-lighting backlight source and passing through the light controlling component permits the display panel to display an image with a desired contrast.
