Description

Technical Field

[0001] The present invention relates to the technical field of price tags, and in particular to a structure of an electronic price tag. Background Art

[0002] An electronic price tag is an electronic display device placed on a shelf that can replace a traditional paper price tag. Electric Shelf Labels have been used in the European retail industry for more than 10 years and are gradually being used in retail stores in North America, Japan, etc. Chinese retailers have realized the drawbacks brought by traditional price tags to store management: time-consuming, laborious, low efficiency, etc. Electronic price tags are not only used for price management to replace manual replacement of paper price tags, but also integrated into all aspects of business, for example, comprehensively boosting sales, improving store operation efficiency, supply chain visualization, CRM, etc. Electronic price tags have become an extension of the enterprise ERP system and an effective tool for refined management.

[0003] Currently, the most popular sizes of electronic price tag products on the market are 4.2 inches, 2.13 inches, 2.66 inches, and 2.9 inches. The structures of these electronic price tags themselves are long and narrow products, resulting in very low resolution. However, customers' requirements for the resolution of electronic price tags are getting higher and higher. Therefore, the existing electronic price tag products cannot meet the market demand. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a structure of an electronic price tag that is long and has a high resolution.

[0005] The technical solution adopted by the present invention is a structure of an electronic price tag, including a structure body. The structure body includes an electronic paper display screen, an outer frame, and a circuit slot disposed between the outer frame and the electronic paper display screen. The electronic paper display screen includes two short sides and two long sides. The circuit slot includes a first slot disposed between the short side of the electronic paper display screen and the outer frame. The structure body further includes a first display chip and a second display chip disposed in one of the first slots. The first display chip and the second display chip are connected together through an FPC circuit board.

[0006] The beneficial effect of the present invention is that for the structure of the electronic price tag adopting the above structure, two display chips are disposed in the circuit slot of the electronic price tag, thereby improving the resolution of the electronic price tag. Moreover, both display chips are placed in the first slot between the short side of the electronic paper display screen and the outer frame. The advantage of such placement is that it occupies less space and ensures the long and narrow structure of the electronic price tag.

[0007] Preferably, the first display chip and the second display chip are placed horizontally and on the same horizontal plane. With this structure, the occupied space of the electronic price tag can be reduced, ensuring that the electronic price tag can achieve the purpose of improving the resolution under the condition of a long strip structure.

[0008] Preferably, the structure body further includes a first gate line and a second gate line. One end of the first gate line is connected to the first display chip, and the other end passes through the short side of the electronic paper display screen and is connected to the display circuit inside the electronic paper display screen. One end of the second gate line is connected to the second display chip, and the other end passes through the short side of the electronic paper display screen and is connected to the display circuit inside the electronic paper display screen. With this structure, the gate lines in the electronic price tag and the display chips are located in the same first groove body, and the display chips transmit data to the display circuit inside the electronic paper display screen through the gate lines. This structure can save the occupied space of the electronic price tag and ensure that the electronic price tag can achieve the purpose of improving the resolution under the condition of a long strip structure.

[0009] Preferably, the line groove further includes a second groove body provided between the long side of the electronic paper display screen and the outer frame. The structure body further includes a first source line and a second source line. One end of the first source line is connected to the first display chip, and the other end passes through one of the second groove bodies and then passes through a long side of the electronic paper display screen and is connected to the display circuit inside the electronic paper display screen. One end of the second source line is connected to the second display chip, and the other end passes through the other second groove body and then passes through the other long side of the electronic paper display screen and is connected to the display circuit inside the electronic paper display screen. With this structure, the first source line in the electronic price tag passes through a long side of the electronic paper display screen and is connected to the display circuit inside the electronic paper display screen, and the second source line passes through the other long side of the electronic paper display screen and is connected to the display circuit inside the electronic paper display screen. The display chips transmit data to the display circuit inside the electronic paper display screen through the source lines. This structure can save the occupied space of the electronic price tag and ensure that the electronic price tag can achieve the purpose of improving the resolution under the condition of a long strip structure.
