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. Specifically, the wireless communication circuit 22b includes at least one of a bluetooth circuit, a local area network circuit, and a wide area internet of things circuit.
In the present embodiment, in order to reduce power consumption, the wireless communication circuit 22b may enter a sleep state in which the wireless communication circuit 22b is in a low power consumption mode in which power consumption thereof is minimized, in the case where a predetermined condition is satisfied, whereby the battery life can be extended. Meanwhile, the wireless communication circuit 22b will periodically receive information in the sleep mode, and if receiving the wake-up information, the wireless communication circuit 22b will leave the sleep state and enter the normal operation state. In the normal operation state, the wireless communication circuit 22b can normally transmit and receive information.
