Abstract: The present disclosure provides a backlight module and a display device. The backlight module includes a plurality of first light sources and a diffusion plate. In a 3D display mode, the first light sources belong to different scanning areas, each of which corresponds to a display area. The backlight module further includes a barrier structure provided corresponding to the respective scanning areas and configured to prevent light emitted by first light sources in the scanning areas other than a current scanning area from entering into a display area corresponding to the current scanning area. In the backlight module of the present disclosure, the barrier structure is provided corresponding to each scanning area, which can prevent light emitted by first light sources in other scanning areas from entering into the display area corresponding to the current scanning area.

Abstract: Embodiments of the present invention relate to a color temperature tuning method, a color temperature tuning apparatus, and a display apparatus. The color temperature tuning method includes the steps of: matching an input color temperature signal with a color temperature value in the color temperature lookup table, and extracting a current signal corresponding to the color temperature value matching with the input color temperature signal from the color temperature lookup table; and controlling a light emitting device to emit light according to the current signal. According to embodiments of the present invention, intermediate calculation process is omitted and time for tuning the color temperature is shorten. Currents flowing through the blue and green light emitting elements are controlled to emit lights to excite red fluorescent powder, so that the LED emits lights having various color temperatures, and tuning accuracy of the color temperature and user experience are improved.

Abstract: The general inventive concepts provide a side-light type backlight unit. The side-light type backlight unit comprises a light guide plate and a light source located at the side of the light incident surface of the light guide plate. The light source comprises a circuit board which comprises a first region opposite to the light incident surface of the light guide plate and a second region adjacent to the first region. The first region and the second region are provided with LED lamps. By arranging LED lamps in both the first region and the second region of the circuit board of the side-light type backlight unit, the incident light of the side-light type backlight unit is increased, thereby improving the luminance of the side-light type backlight unit in 3D state. The disclosure further provides a display device comprising such a side-light type backlight unit.

Abstract: The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform.

Abstract: The present invention provides a diffuser plate assembly. The diffuser plate assembly includes a first diffuser plate and a second diffuser plate located under the first diffuser plate, and a gap is formed therebetween. Correspondingly, the present invention also provides a backlight comprising the diffuser plate assembly and a display device comprising the backlight. Compared with the prior art, the diffuser plate assembly provided by the present invention can enable light emitted by a light source to irradiate a display panel more uniformly, and the thicknesses of the backlight and the display device can be reduced.

Abstract: Embodiments of the present invention relate to a profiled light guide plate, a backlight module and a liquid crystal display device. In the profiled light guided plate according to the embodiments of the present invention, because the reflectivity of the profiled assembly is less than that of the light entry assembly, the emergent angle of the light beam entering into the profiled assembly from the light entry assembly is larger than the incident angle thereof, which causes the light beam entering from the light entry assembly into the profiled assembly to converge towards the central part of the profiled assembly, away from the ramp of the profiled assembly, thereby decreasing the amount of light leakage from the ramp.

Abstract: Various embodiments of the present invention are generally directed to an apparatus and method for low temperature physical vapor deposition (PVD) of an amorphous thin film layer of material onto a substrate. A PVD chamber is configured to support a substrate and has a cathode target with a layer of sputtering material thereon, an anode shield, and a magnetron assembly adjacent the target. A high impulse power magnetron sputtering (HiPIMS) power supply is coupled to the PVD chamber, the power supply having a charging circuit and a charge storage device. The power supply applies relatively high energy, low duty cycle pulses to the magnetron assembly to sputter, via self ionizing plasma, relatively low energy ions from the layer of sputtering material to deposit an amorphous thin film layer onto the substrate.
