Abstract: The present application provides a method for detecting a broken fanout wire of a display substrate, and a display substrate, and belongs to the field of display technology. In the method for detecting a broken fanout wire, the display substrate includes a base substrate having first and second surfaces opposite to each other, and a plurality of connection structures disposed at intervals on the first surface; and each connection structure includes first and second pads and a fanout wire electrically connecting the first pad to the second pad. The method for detecting a broken fanout wire includes: forming at least one detection unit, which includes: connecting at least two connection structures in series through a connecting part; and measuring a head and an end of the detection unit to obtain resistance of the detection unit, and determining whether there is a broken fanout wire in the detection unit.

Abstract: A lighting apparatus includes a base plate, a driver module, a light source, a mechanical switch, a main housing, and a manual switch. The driver module is disposed on a top surface of the base plate. The light source is also disposed on the top surface of the base plate. The mechanical switch is disposed on the base plate. The mechanical switch has multiple states to be selected. The driver reads a selected state to control the light source. The main housing encloses the base plate. The manual switch is disposed on the main housing. An operating part of the manual switch is exposed outside the main housing to be operated by a user. When a user moves the operating part of the manual switch, the connecting part of the manual switch carries the mechanical switch to change the selected state.

Abstract: A silicon-carbon composite material, a preparation method thereof, and a secondary battery are provided. The silicon-carbon composite material includes a silicon-carbon composite core and a carbon coating layer coated on the silicon-carbon composite core, and multiple closed pores are dispersed in the silicon-carbon composite core. The preparation method includes steps of (I) a surface modification treatment of a high-molecular polymer, (II) a preparation of a nano-silicon dispersion, (III) a preparation of a first precursor, (IV) a preparation of a second precursor, and (V) carbon coating. The closed pores in the silicon-carbon composite core can effectively alleviate the significant volume effect of silicon generated during lithium intercalation and deintercalation, and the combination of the silicon-carbon composite core and the carbon coating layer can ensure structural stability and high strength of the material.
