1 and 2 , the electronic paper display device with wireless communication function of the present application includes: a device body 110 , an electronic paper display module 120 , a driving mainboard 130 and a wireless communication module 140 .

The device body 110 may be made of plastic or metal. The device body 110 may be a housing of an electronic paper display device. In some embodiments, the device body 110 may be in the shape of a rectangular frame. Of course, the device body 110 may also be designed in other shapes according to actual application requirements, which is not limited here.

The electronic paper display module 120 is disposed on the device body 110. The electronic paper display module 120 is mainly used to realize the display function of the electronic paper display device. The electronic paper display module 120 can be used to dynamically display patterns and to display price information in a fixed manner. The electronic paper display module 120 adopts electronic paper technology, which has the advantage of low energy consumption, helps to reduce energy consumption and carbon emissions, and improves the energy-saving and environmental protection effect of the device.

The driving mainboard 130 is disposed on the device body 110 . The driving mainboard 130 is mainly used to drive the electronic paper display module 120 to display different contents. The driving mainboard 130 is electrically connected to the electronic paper display module 120 .

The wireless communication module 140 is electrically connected to the driving mainboard 130. The wireless communication module 140 is used to receive the wireless control signal and transmit it to the driving mainboard 130. After the driving mainboard 130 receives the wireless control signal, the price information content fixedly displayed by the electronic paper display module 120 is changed according to the corresponding wireless control signal. The wireless communication module 140 can be set in the driving mainboard 130 in an integrated manner.

In some embodiments, the wireless communication module 140 includes but is not limited to one of a Bluetooth module, a WiFi module, an RFID module, a LoRa module, a 2.4G module, a 2G wireless module, a 3G wireless module, a 4G wireless module, and a 5G wireless module. Any of the above modules can be used as the wireless communication module 140 according to actual applications.

In this embodiment, a wireless control signal can be sent to the wireless communication module 140 of the electronic paper display device, and the wireless communication module 140 receives the wireless control signal and transmits it to the driving mainboard 130, so that the driving mainboard 130 correspondingly drives and controls the electronic paper display module 120 to change the fixed displayed price information content, so that the display device can remotely update the display content without physical connection, which greatly improves the flexibility and convenience of adjusting the display content of the electronic paper display device, especially for multiple electronic paper display devices in the same area, the display content of multiple electronic paper display devices in the same area can be adjusted and managed simultaneously through the wireless control signal. Of course, the wireless control signal can also be used to control the electronic paper display module 120 to change the content of the dynamic display pattern.

In some embodiments, the wireless control signal may come from a control terminal that is signal-connected to the wireless communication module 140. In other embodiments, the wireless control signal may also be sent by a base station and transmitted to the wireless communication module 140, wherein the wireless control signal may be sent by a cloud platform system located in the cloud.

In some embodiments, the electronic paper display module 120 can realize a dynamic display pattern by changing the brightness of the pattern. It is understood that the electronic paper display module 120 can realize a dynamic display pattern by controlling the brightness of the display pattern in whole or in part. Among them, only one pattern can be controlled in brightness to realize a dynamic display pattern. That is to say, when the electronic paper display module 120 does not change the pattern to be displayed, only the brightness of the same pattern is controlled in whole or in part to achieve the effect of dynamically flickering the display pattern.

In other implementations, the electronic paper display module 120 may also display two or more patterns alternately and play them in a loop in the above manner, thereby realizing a dynamic display pattern of the electronic paper display module 120 .

In some embodiments, the electronic paper display module 120 can use a dot matrix display or an eight-segment code display to display price information.

3 is a schematic diagram of the structure of an electronic paper display module in an electronic paper display device with wireless communication function shown in an embodiment of the present application; FIG. 4 is a schematic diagram of the structure of an electronic paper display module in an electronic paper display device with wireless communication function shown in an embodiment of the present application.

Please refer to FIG. 3 and FIG. 4 . In some embodiments, the electronic paper display module 120 includes a first electronic paper display screen 121 and a second electronic paper display screen 122. The first electronic paper display screen 121 is used to dynamically display patterns, and the second electronic paper display screen 122 is used to display price information. The driving motherboard 130 is electrically connected to the first electronic paper display screen 121 and the second electronic paper display screen 122, respectively.

In some embodiments, the first electronic paper display screen 121 can set a display pattern on the cover plate corresponding to the pattern area for displaying the pattern, and the first electronic paper display screen 121 uses its electronic paper display layer to alternately display two colors with different brightness to realize a dynamic flickering (i.e., dynamic) display pattern. Specifically, when the first electronic paper display screen 121 is working, the external light passes through the pattern area and enters the electronic paper display layer, and then the display pattern of the pattern area is dynamically displayed after reflection. By setting different display patterns, the display requirements of colorful patterns and images are met. Among them, the first electronic paper display screen 121 uses the electronic paper display layer to alternately display two colors with different brightness, which can be performed locally, globally, or locally in sequence. Different display modes are used according to different dynamic display requirements. Compared with the method of global refresh, it can be more energy-saving and realize low power consumption and long battery life of the product.

It can be understood that the first electronic paper display screen 121 and the second electronic paper display screen 122 can be two electronic paper display screens that are independent of each other and do not interfere with each other, that is, the first electronic paper display screen 121 and the second electronic paper display screen 122 do not interfere with each other. The driving motherboard 130 drives the first electronic paper display screen 121 and the second electronic paper display screen 122 to display different contents. The first electronic paper display screen 121 and the second electronic paper display screen 122 are used to independently realize dynamic display patterns and display price information, thereby effectively improving the display effect of the electronic paper display device, and facilitating the separate management of the display content of the electronic paper display device, so as to separately adjust the contents displayed by the first electronic paper display screen 121 and the second electronic paper display screen 122, so as to flexibly adapt to different adjustment requirements.

In some embodiments, the first electronic paper display screen 121 and the second electronic paper display screen 122 are symmetrically or asymmetrically adjacently distributed. Wherein, the adjacent distribution of the first electronic paper display screen 121 and the second electronic paper display screen 122 may refer to one of them being arranged adjacent to the other. When the first electronic paper display screen 121 and the second electronic paper display screen 122 are symmetrically adjacently distributed, the display areas of the first electronic paper display screen 121 and the second electronic paper display screen 122 are the same, and when the first electronic paper display screen 121 and the second electronic paper display screen 122 are asymmetrically adjacently distributed, the display areas of the first electronic paper display screen 121 and the second electronic paper display screen 122 are different.

In some embodiments, the display area of the first electronic paper display screen 121 is larger than that of the second electronic paper display screen 122, and the second electronic paper display screen 122 is embedded in the first electronic paper display screen 121. It can be known that the second electronic paper display screen 122 is used to display price information in a fixed manner. Compared with the display function of the first electronic paper display screen 121 for dynamically displaying patterns, the display area of the second electronic paper display screen 122 can be smaller than that of the first electronic paper display screen 121, and the second electronic paper display screen 122 can be embedded in a preset position of the first electronic paper display screen 121 according to actual application requirements. For example, the second electronic paper display screen 122 can be embedded in the lower right edge of the first electronic paper display screen 121. For another example, the second electronic paper display screen 122 can be embedded in the upper right edge of the first electronic paper display screen 121.

In some embodiments, the second electronic paper display screen 122 is embedded in the first electronic paper display screen 121, and the second electronic paper display screen 122 is flush with the first electronic paper display screen 121. In other words, when the second electronic paper display screen 122 is embedded in the first electronic paper display screen 121, the first electronic paper display screen 121 and the second electronic paper display screen 122 form a display area with flush edges, which effectively improves the overall display effect of the electronic paper display device.

In some embodiments, the first electronic paper display screen 121 and the second electronic paper display screen 122 are respectively black and white electronic paper display screens or color electronic paper display screens. Among them, the black and white electronic paper display screen can display black or white, and the color electronic paper display screen can display colors other than black and white. Of course, the display color of the electronic paper display screen can also be achieved by grayscale control.

The electronic paper display module 120 and the driving main board 130 are fixedly installed through the first mounting groove 111 and the second mounting groove 112, respectively, effectively enhancing the structural reliability of the product. Among them, the first mounting groove 111 and the second mounting groove 112 can be located at opposite ends of the device body 110, which is more conducive to the thin and light design of the electronic paper display device.

In some embodiments, an anti-collision gap is provided between the first mounting groove 111 and the second mounting groove 112. Thus, through the anti-collision gap, a distance can be reserved for the assembly of the electronic paper display module 120 and the driving main board 130, thereby effectively avoiding collision and damage between the electronic paper display module 120 and the driving main board 130.

In some embodiments, a protective base plate (not shown) is further provided on the side of the driving main board 130 away from the device body 110, and the driving main board 130 is protected by the protective base plate, thereby effectively increasing the service life of the product.
