The present invention belongs to the field of display technology, in particular to a power supply control method for display device and a display device. The power supply control method for a display device comprises: acquiring images of a room where the display device is located; judging whether there is any person in the room; when determining that there is a person in the room, further recognizing an action state of the person in the room and judging whether the person in the room has a demand of watching the display device; according to a result of judging that there is no person in the room or that the person in the room has no demand of watching, cutting power supply of the display device off.

Power supply control method for display device and display device

The embodiments of the present invention relate to a color management method and device, the method comprises: RGB values is acquired from image signal inputted from external device; the corresponding transmittance of red pixel, transmittance of green pixel, and transmittance of blue pixel are calculated with an formula according to said RGB values and pre-stored system transition matrix with standard transition matrix; a control signal to control a driving voltage and/or luminance of light source corresponding to the red, green and blue pixels of the display device is generated according to the calculated transmittance of red pixel, transmittance of green pixel, and transmittance of blue pixel, so as to control the display device to perform the color display. The color management method enables the display device to accurately restore the reproduction color information, thereby effectively solving the color distortion problem of the display device.

Color management method and device

The present invention relates to an edge-lighting LED backlight and LCD. The edge-lighting LED backlight comprises an LED light bar and a light guide plate, wherein a reflector is disposed between the LED light bar and the light guide plate, holes are set on the reflector, and light emitted from the LED light bar enters into the light guide plate through the holes. An LCD comprises the above edge-lighting LED backlight. In the above solution, the surface reflectance of the LED light bar is improved, the light loss is decreased and the utilization rate of light is improved by disposing the reflector between the LED light bar and the light guide plate, which decreases the quantity of the LEDs and the cost of the backlight.
