    Abstract: A display device including at least one emission area emitting light and a transmission area adjacent to the at least one emission area and transmitting external light. The display device includes a substrate and a circuit element including at least one transistor and a storage capacitor disposed on the substrate. An insulating layer is disposed on the circuit element and includes a contact hole. A first transparent electrode is disposed on the insulating layer and is electrically connected to the circuit element through the contact hole. At least one light-emitting diode is disposed on the first transparent electrode and defines the at least one emission area. The at least one light-emitting diode comprises a PN diode including inorganic semiconductor based-materials. A portion of the first transparent electrode is located in the transmission area.

    Abstract: A hologram display device includes a light source unit, a light guide plate, a spatial light modulator, a sensing unit, and a light source driving unit. The light source unit includes a plurality of light sources and emits light when at least one of the plurality of light sources is turned on. The light guide plate converts the light emitted thereto from the light source unit to a planar light beam. The spatial light modulator spatially modulates the planar light beam to produce a hologram image. The sensing unit senses a position of a user watching the hologram image, and the light source driving unit turns on the at least one of the plurality of light sources, based on information on the position of the user obtained by the sensing unit.

    Abstract: 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.

    Abstract translation: 从对应于调光区域的图像信号中提取多个灰度值，以计算灰度值的平均值，以及方差，标准偏差，峰度，偏度，中心时刻 ，并使用平均值计算图像力矩。 然后，使用所计算的值确定与调光区域对应的代表灰度值，并且基于代表灰度值来确定包括在调光区域中的光源的调光功能。 然后，基于调光功能驱动包括在调光区域中的光源。

    Abstract: A head-up display includes: a plurality of displays having a plurality of pixels and configured to emit lights from each of the plurality of pixels; a plurality of collimators configured to receive the lights emitted from each pixel of the plurality of pixels of the plurality of displays and output collimated lights by collimating the lights; and a diffractive optical element configured to receive the collimated lights from the plurality of collimators, diffract the collimated lights, emit the collimated lights at angles substantially equal to respective angles at which the collimated lights are incident to the diffractive optical element, respectively, and generate a virtual image by the collimated lights emitted from the diffractive optical element. The head-up display is reduced in size and capable of generating the virtual image at infinity to allow drivers to view the virtual image without shifting their focal point.
