摘要: A backlight driving circuit for a display apparatus includes a receiver, a signal modulation detector and a driver. The receiver receives a clock signal and a brightness data signal by a serial transmission and in response to an enable signal. The brightness data signal is synchronized with the clock signal and includes brightness information. The signal modulation detector detects a modulation of the brightness data signal, based on at least one of the clock signal and the enable signal, and outputs a control signal based on a detected result thereof. The driver receives the brightness data signal, in synchronization with the clock signal, selects one of the brightness data signal and a predetermined reference brightness data signal in response to the control signal, generates a driving voltage using the selected brightness data signal, and provides the driving voltage to the backlight unit to control the brightness of the backlight unit.

摘要: A display apparatus includes plural light guide plates each including a light incident surface and a light output surface, plural light sources providing light to the light guide plates, and a display panel receiving the light to display an image. The light guide plates have a rectangular shape, are spaced apart from each other and are in a same plane. The light sources are disposed between two adjacent light guide plates. Each of the light sources includes a light emitting surface, and provides the light to the light guide plates through the light emitting surface. The light emitting surface of the light sources is inclined with respect to one side of the light guide plates.
