Figure 1-6As shown, an embodiment of the present invention provides an electronic signboard, comprising a shell 1, an electrophoretic display screen 2 and a drive interface 3, wherein the electrophoretic display screen 2 and the drive interface 3 are installed in the shell 1. Preferably, the shell 1 comprises an inner shell 11 and an outer shell 12, wherein the inner shell 11 and the outer shell 12 are fixedly connected, the electrophoretic display screen 2 and the drive interface 3 are located between the inner shell 11 and the outer shell 12, and the outer shell 12 is a transparent shell, wherein the display surface of the electrophoretic display screen 2 faces the outer shell 12. The drive interface 3 is electrically connected to the electrophoretic display screen 2, and is used to receive a display drive signal and transmit it to the electrophoretic display screen 2, thereby changing the display characters of the electrophoretic display screen 2, thereby forming a signboard with a new logo. Since the electronic signboard itself does not have a drive circuit, but only receives an external display drive signal through the drive interface 3, the cost of the drive circuit board is saved, which greatly reduces the cost of the electronic signboard and makes it easier to promote and apply. During use, the drive interface 3 is connected to the drive connector of the external host to receive the display 4 drive signal, so that the electrophoretic display screen 2 displays the text or pattern corresponding to the display drive signal, and then the drive interface 3 is separated from the drive connector of the external host. Since the electrophoretic display screen 2 has a bistable characteristic, the displayed text or pattern can be maintained until the next display drive signal is received. In a preferred embodiment, the electrophoretic display screen 2 is powered by the drive interface 3, that is, the electronic signboard 10 is not provided with a power supply or a dedicated power interface. Only when the drive interface 3 is connected to the drive connector of the external host, power is obtained from the drive connector of the external host to power the electrophoretic display screen 2. Since the electrophoretic display screen 2 has a bistable characteristic, the characters are still displayed after the power is turned off. In another preferred embodiment, the electronic signboard 10 is not provided with a drive circuit 5, and the drive circuit 5 is provided in the external host. To change the characters on electronic signboard 10, connect the drive interface 3 of electronic signboard 10 to the drive circuit 5. Drive circuit 5 on the host generates a display drive signal, which is transmitted via drive interface 3 to electrophoretic display screen 2, causing electronic signboard 10 to display the new characters or image. Because electrophoretic display screen 2 is bi-stable, the characters remain displayed even after power is removed. Disconnecting electronic signboard 10 from drive circuit 5 allows it to be used as a new electronic signboard 10.
