Technical Field

[0002] Currently, the connection between electronic paper and the main control board is mostly fixed by direct soldering. This soldering connection method has significant limitations: the electronic paper and the main control board form an inseparable whole structure. The electronic paper cannot be plugged in or unplugged relative to the main control board, which means that the electronic paper is physically completely attached to the main control board and cannot exist independently of the main control board. When the electronic paper displays specific content, if it is necessary to display or move the displayed content independently, the entire main control board and related circuits must be carried, and the electronic paper cannot be moved independently. Utility Model Content

[0004] The gold finger connector enables a detachable connection between the gold finger module and the main control board, breaking the limitations of traditional fixed soldering of electronic paper to the motherboard. The electronic paper can be displayed independently without the main control board, and can be plugged back in to update the image, realizing electronic paper reuse, reducing costs and improving ease of use.

[0005] Preferably, a camera circuit with detachable electronic paper further includes a judgment module connected to the gold finger module. The judgment module is used to compare and verify the identification information of newly connected electronic paper. The judgment module has a built-in verification key for the original manufacturer's compatible electronic paper. The control module reads the key from the judgment module and performs a comparison to verify whether it is an original manufacturer's compatible screen. The control module only transmits image data when verification is successful, effectively preventing the access and use of non-original screens, avoiding display abnormalities caused by hardware specification differences in non-compatible screens, and ensuring the compatibility of the circuit and the screen.

[0006] Preferably, the main control board further includes a communication module, which is connected to the control module and the gold finger receiving module. This enables data uploading and downloading, expanding the circuit's remote interaction capabilities and application scenarios.
