Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, in particular to a PIN pin guide structure of an LCD display component. Background Art

[0002] Since its development, LCD (Liquid Crystal Display) technology has been widely used in numerous electronic device applications. With the increasing diversification and intelligence of electronic devices, LCDs are required to display more complex information. Therefore, to meet these complex display requirements, LCDs typically require multiple pins (PINs) to connect to holes in the PCB (Printed Circuit Board). Multiple PINs improve data transmission capabilities, enhance electrical connection stability, and support multiple drive modes. During the assembly process of the LCD, PINs, and PCB, plastic brackets are typically installed. During use, devices may be subject to vibration, shock, or temperature fluctuations. Plastic brackets can buffer external stresses and prevent problems such as poor solder joints or breakage caused by physical displacement, thereby improving the reliability and stability of the entire electronic module. Furthermore, plastic brackets can also provide auxiliary electromagnetic shielding, reducing the impact of external electromagnetic interference on the LCD display signal. They also prevent electromagnetic radiation generated by the LCD itself from interfering with other electronic components, thereby ensuring the stability of the device's internal electromagnetic environment. In existing technologies, PINs are usually directly connected to PCB holes through holes in the plastic bracket. However, due to the large number of PINs, it is difficult to accurately align the PINs with the plastic bracket and PCB holes during the assembly process, resulting in assembly difficulties and low work efficiency.
