Document Type and Number:
WIPO Patent Application WO/2019/205736
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are an electronic component and a projection device. The electronic component comprises a main module and a plurality of sub-modules, the main module being used to control the plurality of sub-modules; each of the sub-modules comprises a processing unit and a first connector; and the first connector comprises a plurality of address line connection ports for connecting address lines, the plurality of address line connection ports being connected to the processing unit, the processing unit being used to determine an address code of the sub-module according to a detected level of each of the plurality of address line connection ports, the level of each of the plurality of address line connection ports being determined by whether each of the plurality of address line connection ports is connected to the address line. The electronic component makes it unnecessary to provide a dial switch needed for address code configuration as well as the panel for placing the dial switch, saving resources, and also solving the problem of communication errors between a master control system and subsystems caused by the risk of dialing errors of the dial switch.
