摘要： A display apparatus includes a light guide plate, a light source unit and a display panel. The light guide plate includes an incident surface, an exit surface and an opposite surface opposite to the exit surface and guides a light incident into the incident surface toward the exit surface. The light source unit includes a light source which generates light and is disposed adjacent to the incident and has an emitting surface inclined with respect to the incident surface. An extension line of a normal line of the emitting surface passes through the opposite surface, and the light is incident into the incident surface while being inclined toward the opposite surface. The display panel displays an image by receiving the light emitted from the exit surface.

摘要： A display device with improved display quality is provided. The display device includes an LED light source emitting light, a display panel receiving the light to display an image, and a backlight driver adjusting the magnitude and the duty ratio of an LED current I_LED flowing through the LED light source. The waveform of the LED current I_LED includes at least one of a rising section in which the magnitude of the LED current more gradually increases from a turn-off current value to a peak value, and a falling section in which the magnitude of the LED current more gradually decreases from the peak value to the turn-off current value. This acts to reduce waterfall noise.

摘要： A plurality of gray-scale values is extracted from image signals corresponding to a dimming area to calculate a mean value of the gray-scale values, and at least one of a variance, a standard deviation, a kurtosis, a skewness, a central moment, and an image moment is calculated using the mean value. Then, a representative gray-scale value corresponding to the dimming area is determined using the calculated values, and a dimming function for the light sources included in the dimming area is determined based on the representative gray-scale value. Then, the light sources included in the dimming area are driven based on the dimming function.

摘要： In a display apparatus having a backlight unit, a light unit includes plural light source strings commonly connected to an output terminal of a boosting circuit to generate light in response to a light source driving voltage. The light source strings are grouped into plural light generating groups. Plural driving circuits are respectively connected to the light generating groups, and each driving circuit sequentially outputs feedback voltages from the light source strings of a corresponding light generating group. A minimum voltage detecting circuit compares the feedback voltages with each other from the driving circuits to detect a minimum voltage and outputs a control signal according to the detected minimum voltage. A voltage control circuit controls a voltage level of the light source driving voltage in response to the control signal. Accordingly, although the number of the driving circuits increases, power consumption used in each driving circuit may be reduced.
