Fig. 1 is a schematic structural view of an electronic paper bracelet according to an embodiment of the invention. Fig. 2 is a schematic circuit diagram of an electronic paper handle ring according to an embodiment of the present invention. As shown in fig. 1, the electronic paper-based smart grip billboard of this embodiment includes a billboard body 1 and an electronic paper assembly 2. The signboard main body 1 has a grip member 11 and a receiving portion 12 suitable for gripping. The electronic paper assembly 2 has an electronic ink screen 21 and a circuit assembly 22 (see fig. 2) electrically connected to each other. The electronic paper component is disposed in the housing portion 12.
Fig. 2 is a schematic circuit diagram of an electronic paper assembly of the electronic paper-based smart handhold billboard of this embodiment. As shown in fig. 2, the electronic paper assembly 2 includes an electronic ink screen 21 and a circuit assembly 22. The electronic ink display screen is a screen using electronic ink. Electronic ink screens are also known as electronic paper display technology. Electronic ink is a new method and technology for revolutionizing the display of information. Like most conventional inks, electronic ink and the lines that change its color are printable on many surfaces, from curved plastic, polyester film, paper, to cloth. The difference with conventional paper is that electronic ink changes color when powered on and can display changing images, such as a calculator or cell phone. A plurality of microcapsules with small volume are attached to the surface of the electronic ink screen, black particles with negative electricity and white particles with positive electricity are encapsulated, and the particles with different colors are orderly arranged by changing the charges, so that a clearly black-white visual effect is presented. The electronic ink screen is composed of two substrates, on the electronic ink screen an electronic ink formed from countless small transparent granules is coated, said granules are formed from several black and white granules with positive and negative charges which are sealed in the interior liquid microcapsules, and the charged granules with different colours can be moved towards different directions due to the difference of applied electric field, so that the black or white effect can be displayed on the surface of display screen. Thus, black and white patterns and characters like printed matters can be displayed on the surface of the electronic paper, the electronic paper looks very similar to paper, and the reflection phenomenon of the traditional liquid crystal display is avoided in sunlight. Meanwhile, only when the color of the pixel changes (for example, from black to white), the power is consumed, and the picture on the display screen can be still reserved after the power is turned off, so that the power is saved very much.
With the development of technology, electronic ink display screens can be rendered in color in addition to black and white.
Further, the circuit assembly 22 includes a display driving circuit 22a and a wireless communication circuit 22 b. The display driving circuit 22a is electrically connected to the electronic ink screen 21, and is configured to drive the electronic ink screen to perform displaying and refreshing. The wireless communication circuit 22b is used for wirelessly receiving the advertisement content to be displayed and sending the advertisement content to the display driving circuit.
In the present embodiment, the wireless communication circuit 22b includes a Lora communication module 22b1 and an LTE CAT1 communication module 22b 2. Lora (Long Range Radio) is a low power wireless standard for local area networks created by semtech corporation. The Lora communication module 22b1 is a hardware communication circuit that communicates in compliance with the Lora protocol. The transmission distance of the Lora communication module can reach 2-5Km in towns and 15Km in suburbs. The working frequency of the frequency band is the ISM frequency band including 433, 868, 915MHz and other frequency bands. The Lora modulation scheme is based on a spread spectrum technique, a variant of the linear modulation spread spectrum (CSS), and has a Forward Error Correction (FEC) capability. Therefore, the Lora communication module has the characteristics of long distance and low power consumption, but the data transmission rate is low. LTE (Long Term Evolution) is a Long Term Evolution of The UMTS (Universal Mobile Telecommunications System) technical standard established by The 3GPP (The 3rd Generation Partnership Project) organization. LTE CAT1 refers to LTE UE-Category 1, also known as eMTC, or LTE-M. According to the definition of 3GPP, the UE-Category is classified into 10 classes of 1-10 according to the expected quality of Service (QoS). Different CAT classes correspond to different quality of service. The goal of CAT1 is to serve the internet of things and achieve the goal of low power consumption and low cost LTE connectivity. CAT1 has advantages over NB-IoT and 2G modules in terms of network coverage, speed and latency. Compared with the traditional CAT4 module, the CAT4 module has the advantages of low cost and low power consumption. Meanwhile, the CAT1 is suitable for the current home 4G network, and is very suitable for application scenarios requiring cost performance, delay, coverage and communication speed.
In the present embodiment, the display driving circuit 22a and the wireless communication circuit 22b are controlled by a controller (not shown in the figure) to perform reception and display of data. The electronic paper handle ring of the embodiment may further include a memory (not shown in the figure) for storing image data that needs carousel.
In the present embodiment, to reduce power consumption, the wireless communication circuit 22b maintains the Lora communication module 22b1 in a low power consumption state in an operating state while maintaining the LTE CAT1 communication module in a powered-off state. Thus, the Lora communication module periodically attempts to receive signals, minimizing its own power consumption, while the LTE CAT1 communication module remains completely without power consumption. The Lora communication module informs the controller after receiving the notification message, and the controller further controls the LTE CAT1 communication module to power on to enter the receiving mode.
