What is a thin film transistor? The basic structure, characteristics, working principle, control module, application, installation steps, and development history of thin film transistors 3

1. Preparation work: Before installing thin film transistors, it is necessary to prepare the required materials and tools. These materials include thin film transistors, substrates, wires, packaging materials, etc. Tools include welding iron, pliers, power supply, etc.

2. Preparation of substrate: The substrate is the supporting structure of the thin film transistor and requires some surface treatment. Firstly, clean the substrate to remove impurities and dirt from the surface. Then, a layer of conductive material, usually copper or silver, is coated to provide a path for current transmission.

3. Manufacturing thin film transistors: Thin film transistors are typically composed of several thin layers of material, including semiconductor layers, gate layers, insulation layers, and source/drain layers. These layers can be manufactured through methods such as chemical vapor deposition, physical vapor deposition, sputtering, etc.

4. Installing thin film transistors: Carefully place the manufactured thin film transistors on the substrate and connect the source/drain layers of the thin film transistors to the wires on the substrate using soldering iron. Ensure that the connection is secure and there is no short circuit.

5. Encapsulation: Encapsulate the installed thin-film transistor to protect it from damage such as dust and moisture in the environment. Encapsulation typically uses transparent materials such as glass or plastic.

6. Testing and Debugging: After installation, test and debug the thin film transistor to ensure its normal operation. This includes checking whether the transmission of current and voltage is normal, as well as whether the thin film transistor can correctly control the liquid crystal display screen.
