The heat dissipation device is applied to a display device, including a temperature monitoring unit, configured to monitor an environment temperature of each predetermined region of the display device; a control unit, connected to the temperature monitoring unit, configured to determine regions to be cooled according to a monitoring result of the temperature monitoring unit and then send a control instruction to a movement unit; the movement unit, connected to the control unit, and configured to move at least one heat dissipation fan to the regions to be cooled in response to the received control instruction; and the at least one heat dissipation fan connected to the movement unit.

Abstract: The present invention provides a method for burning device keys, wherein the method for burning comprises the steps of: step a: computing device keys to be sent at an operating device end to obtain a first verification code; step b: sending the device keys to be sent to a receiving device end, and controlling the receiving device end to store the received device keys into the receiving device end; step c: controlling the receiving device end to compute the received device keys to obtain a second verification code; step d: comparing the first verification code with the second verification code; step e: finishing the burning method when the first verification code matches the second verification code, and performing the steps b, c, d and e again when the first verification code does not match the second verification code. The present invention also provides a burning system.

Abstract: The present disclosure provides a display module and a display device. The display module includes a backlight module and a display screen arranged in front of the backlight module. The display module further includes a front frame that is shared with the display device. The backlight module and the display screen in the display module are directly fixed together by the front frame.

Abstract: The present disclosure provides a backlight source and a display device. A rigid element is arranged between a light strip of the backlight source and a light-entering surface of a light guide plate. One end of the rigid element is fixed onto the light strip, and the other end of the right element is fixed onto the light guide plate, so as to maintain a constant distance between the light strip and the light-entering surface of the light guide plate. An elastic element is arranged between the light strip and a back plate and at a side of the light strip opposite to the light-entering surface of the light guide plate. When the light guide plate is thermally deformed, a deformation force generated by the light guide plate is applied to the rigid element, so push the light strip to press against the elastic element.

Abstract: 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.

Abstract: The present invention provides a remote controller, a display device and a remote control display system. The remote controller comprises a control module and a transmitter module electrically connected to each other, wherein the remote controller is provided with at least five direction keys each corresponding to a different control direction, and when any one of the direction keys is pressed, the control module can control the transmitter module to transmit a direction remote control signal corresponding to the pressed direction key to a remotely controlled display device. The present invention can enable a corresponding object on the remotely controlled display device to move in more directions, thereby significantly simplifying operation steps required for carrying out moving or positioning operation through the remote controller.

Abstract: A portable display device includes a display element provided with a main screen thereon, the portable display device further includes a secondary screen capable of being incorporated with the main screen. By providing a secondary screen, a display region of the portable display device can be extended as required, thereby allowing to run more applications to satisfy user's demands. And at the same time, the drawing structure can extend the display region in a convenient and steady manner.

Abstract: The present invention provides a reminding method of program broadcasting and a reminding system of program broadcasting and a display device. The reminding method comprises: identifying a favorite program of a user; acquiring a broadcasting time of the favorite program; and sending reminding information of program broadcasting when an interval between the current time and the broadcasting time of the favorite program is less than or equal to a reminding time interval. According to the reminding method, the user may be prevented from missing the broadcasting of the favorite program, broadcasting channels no longer need to be sequentially searched after the user receives the reminding information, and aimless waiting for the program is no longer needed, so that the time and effort of the user are saved, and great convenience is provided for the user to timely and accurately watch the favorite program.
