Abstract:
1. A display device comprising: a first substrate; a dimming controller; light emitting device (LED) light sources mounted on the first substrate; light source drivers to drive the LED light sources; a light source controller configured to control the light source drivers in response to dimming signals output from the dimming controller; a light guide plate including a side surface on which light emitted from the LED light sources is incident and a back surface from which light is emitted in a direction different from a direction of the light incident on the side surface; and a panel disposed on the light guide plate and displaying a video image, wherein at least first and second LED light sources adjacent to each other, among the LED light sources on the first substrate, are controlled differently from other LED light sources on the first substrate based on the video image, wherein the light guide plate includes a pattern positioned therein corresponding to areas of the LED light sources, wherein the pattern is to prevent the light emitted from one light source from being distributed to the area of neighboring light source, wherein the pattern is formed in any one or more of a first shape and a second shape, the first shape being narrow in a lower portion and wide in an upper portion, and the second shape being wide in a lower portion and narrow in an upper portion, wherein the light source drivers are respectively designated by different addresses to control the LED light sources individually, and wherein the light source controller receives the signals output from the dimming controller via a Serial Peripheral Interface.
