摘要： A backlight assembly includes a light source unit, a reflective element, a receiving container and a diffusion plate. The light source unit has at least one point light source, and the point light source emits light toward a side surface direction. The reflective element has a reflective surface, and the reflective surface is separated from the point light source toward the side surface direction by a predetermined distance for reflecting the light from the point light source toward an upper direction. The receiving container has a bottom plate and a side wall, for receiving the light source unit and the reflective element. A diffusion plate is disposed over the light source unit and the reflective element. Thus, uniform brightness may be enhanced, and the thickness of a display apparatus may be reduced.

摘要： A light source apparatus includes a light source, a duty determining part, a luminance shifting determining part and a duty compensation part. The light source includes a plurality of light-emitting blocks. The duty determining part determines a duty of light-emitting blocks by using a block representative value obtained from a plurality of image blocks that are divided in accordance with a plurality of light-emitting blocks. The luminance shifting determining part compares block representative values of a previous frame with block representative values of a current frame to determine whether a luminance shifting is generated at an adjacent light-emitting block. The duty compensation part compensates a duty of the adjacent light-emitting blocks when the luminance shifting is generated at the adjacent light-emitting blocks. Thus, the duty of the adjacent light-emitting blocks determined as a block representative value is compensated so that an occurrence of flicker may be decreased.
摘要翻译：光源装置包括光源，占空比确定部分，亮度转换确定部分和占空比补偿部分。光源包括多个发光块。占空比确定部通过使用从根据多个发光块划分的多个图像块获得的块代表值来确定发光块的占空比。亮度偏移确定部分将先前帧的块代表值与当前帧的块代表值进行比较，以确定在相邻发光块处是否产生亮度偏移。当在相邻的发光块产生亮度偏移时，占空比补偿部补偿相邻的发光块的占空比。因此，确定为块代表值的相邻发光块的占空比被补偿，从而可以减少闪烁的发生。

摘要： A light-generating device includes a driving substrate and a plurality of light source arrays. The driving substrate has a rectangular planar shape. The plurality of light source arrays is formed on the driving substrate. The light source arrays include at least one light emitting diode to generate light in response to power being applied through the substrate, and the light source arrays are spaced apart from each other. Thus, heat generated from the light-generating device is rapidly dissipated from the light-generating device, improving brightness of the light, brightness uniformity of the light and color reproducibility of the light.

摘要： A backlight assembly a plurality of first light-emitting chips for emitting light and a thermistor for indicating the temperature of the first light-emitting chips. The first light-emitting chips emit first color light and are connected in series to each other. The thermistor may be connected in series to the first light-emitting chips and has an electrical resistance that decreases with an increase of its temperature. The light amount emitted by the first light-emitting chips is controlled by pulse width modulating the current driving the first light-emitting chips based on the temperature (resistance) of the thermistor and based on received image data. Thus, a decrease in brightness due to temperature variation may be compensated for while performing color dimming.
