    摘要： A display device includes a display panel and a light emitting device to supply light to the display panel. The light emitting device includes a light emitting element emitting a first light and a fluorescent layer receiving the first light, transmitting a portion of the first light, converting a remaining portion of the first light to a second light having a wavelength range different from the first light, and emitting the second light. The second light emitted by the fluorescent layer has a full width at half maximum equal to or larger than 110 nanometers (nm) and a light emission spectrum having a peak wavelength within a wavelength range of about 530 nm to about 560 nm. The second light has a light emission intensity corresponding to 10 to 30 percent of a peak light emission intensity of the first light.

    摘要： A display apparatus includes a display panel, a backlight unit, a backlight control circuit, sensors, a read-out circuit and a sensor auxiliary circuit. The display panel includes pixels and displays an image. The backlight unit includes a first light source which emits a first light in a infrared light range. The backlight control circuit controls a brightness of the first light source. The sensors sense an external signal and outputs first sensing signals. The read-out circuit outputs the first sensing signals as second sensing signals. The sensor auxiliary circuit compares a maximum value and a minimum value of the second sensing signals and provides a brightness control signal to the backlight control circuit based on the compared difference to control the brightness of the first light source.

    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.

    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.

    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.
