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： Provided is a display apparatus, which includes a light source unit providing light, a light guide panel guiding the light to a display panel, the display panel receiving the light to display an image, and a bottom chassis accommodating the light guide panel, the light source unit, and the display panel. The light guide panel is adjacent to the light source unit, and includes a light incident surface to which the light is incident, a light output surface from which the light is emitted, and an opposite surface opposed to the light output surface. The display panel faces the light output surface and receives the light to display an image. The bottom chassis has a bottom facing the opposite surface. The light guide panel includes a coupling member protruding from the opposite surface and coupled to the bottom chassis.

摘要： A light guide plate includes an incident surface receiving incident light from a light source, an exit section that outputs exit light having a light distribution different from a light distribution of the incident light and a reflective section opposite to the exit section. A plurality of first patterns are formed on the exit section while being arranged in a first direction of the exit section to distribute the exit light with maximum brightness in a direction perpendicular to the exit section. A plurality of second patterns are formed on the reflective section to scatter the incident light.
