The invention relates to a mainboard circuit, a display module and a display device, and belongs to the field of electronics. The mainboard circuit comprises a display connection port that comprises amodule recognition terminal, and an analog-to-digital converter that is connected with the module recognition terminal and configured to convert an analog voltage on the module recognition terminal into a digital signal including a module identifier, wherein the display connection port is used for being connected with a mainboard connection port of the display module, so as to receive the analogvoltage from the display module based on a connection between the module recognition terminal and an identifier signal terminal in the mainboard connection port. The display module comprises a mainboard connection port that comprises the identifier signal terminal, and a voltage converter connected with the identifier signal terminal and configured to provide the analog voltage corresponding to the module identifier of the display module to the identifier signal terminal. According to the mainboard circuit, display module and display device provided by the invention, recognition between the more identifier information can be supported based on fewer hardware circuits.
Description
technical field [0001] The present disclosure relates to the field of electronics and electricity, in particular to a motherboard circuit, a display module and a display device. Background technique [0002] On the main board circuits of various electronic products, corresponding interface circuits are usually provided to identify the identification information (ID) of the connected hardware, such as model, supplier, production date and so on. For products such as display modules, two terminals (PIN) will be reserved in the display connection port of the motherboard circuit in the related art to detect whether each terminal is in a high voltage, low voltage or high impedance state. To realize the distinction between different display modules. However, with the increase in the number of display module categories and the technical trend of thinner and lighter electronic products, the above hardware identification methods are far from meeting actual application requirements. ...
