Description

Technical Field

[0001] The present invention belongs to the technical field of display devices, and in particular relates to an energy-saving display device with zero standby power consumption. Background Art

[0002] With the improvement of living standards, the requirements for the environment are getting higher and higher, and energy conservation and green environmental protection have become the goals that people are constantly pursuing.

[0003] The standby power consumption of display devices such as IFP and TV is also an invisible waste of energy, because traditional display devices are mainly powered by the power board to the mainboard. When in standby mode, only the main circuit is turned off, but some mainboards and power boards are still in working state. The lowest standby power consumption can only be 0.5W. Therefore, the standby power consumption of traditional products is generally 0.5~3W. Calculated based on 16 hours of standby per day, billions of degrees of electricity will be wasted every year. Summary of the invention

[0004] The main purpose of the present invention is to provide an energy-saving display device with zero standby power consumption, solve the problems existing in the prior art, and achieve zero standby power consumption by adding a light energy panel, optimizing the power panel and the standby circuit of the whole machine.

[0005] In order to achieve the above object, the solution of the present invention is: An energy-saving display device with zero standby power consumption, wherein a light energy board and an energy storage capacitor are added to the display device, and the light energy board absorbs light energy and converts it into electrical energy; in the standby state, the power supply of the power board and the main board of the display device are completely cut off, and the light energy board and the energy storage capacitor supply power to the remote control receiving head and buttons of the display device; after the remote control receiving head or the button receives a power-on signal, the power board starts to supply power to the main board and backlight, and at the same time, the light energy board starts to store charge in the energy storage capacitor.

[0006] After the remote control receiving head or button of the display device receives the standby signal, the light energy board sends a signal to the power board, and the power board cuts off all voltage outputs through the control circuit; at this time, the display device only receives the power-on signal from the remote control and button.

[0007] The power board reserves an interface controlled by the light energy board.

[0008] The light energy panel is an amorphous silicon solar panel.

[0009] When the display device is in a non-standby state, the voltage of the power board is used to charge the energy storage capacitor.

[0010] After adopting the above technical solution, the present invention has the following technical effects: The present invention realizes changing the logical architecture of the remote control receiving head and buttons, adopts a method of controlling power supply by a solar energy board, cuts off power supply to a main board and a power board in a standby state, and only the solar energy board and energy storage capacitors supply power to the remote control receiving head and buttons, thereby achieving zero standby power consumption.
