Abstract: The present disclosure provides a backlight, a display device and a method for controlling backlighting thereof. The present disclosure relates to the field of display technology, and enables a display panel with uniform brightness. The backlight comprises a backplate and a light emitting unit which is arranged on a surface of the backplate. The light emitting unit comprises a substrate and a plurality of light sources which are fixed onto the substrate. The substrate comprises an attached part which is fixed to a central area of the surface of the backplate and a bendable part which forms a preset angle with a non-central area of the surface of the backplate.
Abstract: There is provided a video signal transmission apparatus, a play system and a transmission method. The video signal transmission apparatus comprises: a first interface configured to be connected with a video signal source; a second interface configured to be connected with a display device; a signal receiving unit and a control unit arranged between the first interface and the second interface, the control unit being connected with the display device through the second interface and the signal receiving unit being connected with the video signal source through the first interface. The control unit comprises an acquiring module configured to acquire parameter information of the display device and feed acquired parameter information back to the signal receiving unit.
Abstract: The present disclosure relates to a display technique and provides a multi-screen display apparatus comprising a plurality of display screens, wherein small signal earth wires of the plurality of display screens are connected with each other, large signal earth wires of the plurality of display screens are connected with each other, the small signal earth wires cause small signal grounds of the respective display screens to be connected with each other, and the large signal earth wires cause large signal grounds of the respective display screens to be connected with each other. The plurality of display screens share one power supply, and common-mode choke coils are disposed at signal input terminals of signal boards of the plurality of display screens. The present disclosure further provides a method for eliminating signal interferences in multi screens based on the multi-screen display apparatus.
Abstract: The present disclosure discloses a mold frame, a backlight module and a display device. The mold frame includes sidewalls for limiting a periphery of a light guide plate and optical films in the backlight module, and a boss for limiting the light guide plate and the optical films in a direction perpendicular to an output surface of the light guide plate. The boss is provide with a recess opening towards the light guide plate. The recess is provided with a number of rollers therein in a lengthwise direction thereof. A diameter of the rollers is greater than a depth of the recess. The mold frame is applied to the backlight module. In assembly, the light guide plate, the light source and the optical films are placed in the mold frame.
Abstract: The present invention provides a setting method of a display mode and a display mode configuring system, the setting method comprises the following steps: setting display mode parameters of a first display device; extracting and storing the display mode parameters of the first display device; setting a second display device based on the extracted display mode parameters of the first display device; and making the second display device display based on the display mode parameters of the first display device. In the present invention, through extracting the display mode parameters of the first display device, the display mode of the second display device is set, and compared to the manual setting, the operation is convenient and mistake is not easy to occur, thus on the premise of ensuring setting accuracy, the setting efficiency is increased.
