Once the power is cut off, the electronic display medium will not work, resulting in a black screen, which completely interrupts the advertising display, information inquiry, and information guidance of the medium. , Information release and information interaction. This situation is not only a functional defect in some occasions, but even causes great inconvenience and confusion to the information audience. For example, the electronic display of a bus station will not be able to display the bus line information after a power failure, and a piece of paper is placed at the same time. The quality stop sign is superfluous and at a loss.

The present invention creates a power-off operation mechanism for electronic display media. It covers a crimpable information medium that does not require strong power on the electronic display medium, and automatically shrinks and hides when power is on, without affecting the display of the electronic display medium. And interactive, it will automatically extend and cover the electronic display medium when the power is off, and replace the information release function of the electronic display medium, thus solving the problem of continuous operation after power off. The invention can be widely used in indoor and outdoor electronic advertising screens, public transportation electronic stop signs, information indication screens and information release screens, self-service terminals, etc.

The solution is simple and easy to implement, and only needs a simple power-on/off induction device and a media expansion device, which occupies a small space, can be hidden with the original electronic display media device, and is reliable in operation.

Summary of the invention

In order to solve the display problem of electronic display media after power failure, the present invention provides an operation mechanism and application of electronic display media after power failure. A rollable information medium without strong power is overlaid on the electronic display media. , It automatically shrinks and hides when power is on, does not affect the display and interaction of the electronic display medium, and automatically stretches when power is off, covers the electronic display medium, and replaces the information release function of the electronic display medium, thus solving its continuous operation after power failure problem.

The said electronic display medium is characterized in that it can be a display or interactive device that requires strong power support for the operation of various media itself and its auxiliary devices, including LED display, LCD display, OLED display, PDP display, CRT display Screen or mixing device, etc.

The aforementioned need for strong power support means that its display requires more power for power support compared to the retractable information medium that does not require strong power over it.

The “no need for strong electricity” means that compared with the display or interactive device that needs strong electricity support, its display does not require electricity support or only needs less power support, so that it can be displayed independently or on a smaller power battery after power failure. Independent display under the support of.

The crimpable information medium is characterized in that it can be various advertising papers, advertising cloths or other bendable and foldable information release materials, takes up a small space after shrinking, and can be hidden in the housing and auxiliary devices of the electronic display medium.

The crimpable information medium that does not require strong electricity is characterized in that it can be a variety of advertising papers, advertising cloths or other flexible and foldable information release materials, on which relevant information that needs to be released after power failure can be produced, including publicity , Advertisements and information guidelines, etc., can be referred to as information screens for short.

The retractable information medium that does not require strong electricity is overlaid on the electronic display medium, which is characterized in that the size of the expanded area of the retractable information medium that does not require strong electricity is basically the same as the display area of the electronic display medium. It is completely covered and beautiful.

The automatic shrinking and hiding when powering on is characterized in that the motor is automatically started after power is turned on, or gravity is used to scroll, pull or hang down the retractable information medium that does not require strong electricity to shrink and hide in the housing and auxiliary device of the electronic display medium. So as not to affect the normal display and interaction of the electronic display medium.

The described automatic extension and covering on the electronic display medium when the power is cut off is characterized in that when the strong electricity is cut off, gravity or a low-power battery is used to start the motor, hang down or roll, and pull the retractable information medium without strong electricity. After unfolding, it will cover the electronic display medium and replace the electronic display medium to perform the information release function.

The method of shrinking and stretching of the information screen is not limited to the way of shaft curling, but can also be folded or louvered for shrinking and stretching; the direction of contraction and stretching of the information screen can be vertical or horizontal; the information screen shrinks , The extended drive mechanism can be installed in any of the four directions of up, down, left and right.

The information screen is installed between the screen of the electronic station and the glass panel, and the rotating shaft is fixedly installed above the glass panel, as shown in Figure 3. The platform line information curtain should be basically the same size as the transparent glass of the glass panel. When the curtain paper is unfolded, it can cover the screen instead of providing basic information. After being rolled up, it will be hidden above the transparent glass part without affecting the screen display.

The present invention only needs a simple power-on/off induction device and a media expansion device, which occupies a small space, can be hidden with the original electronic display media device, and is reliable in operation.
