1604 LCD module is a highly integrated LCD display module, usually used in devices that need to display more characters and information.
High Integration: covers display screen, drive circuit and control logic, simplifying the manufacturing process. , design and layout
Large Display Area: provides a display structure of 16 characters × 4 lines, rich display information, suitable for displaying large amounts of text and data.
Good Visibility: provides clear display effects and a wide range of viewing angles.
Stability And Reliability: Using COB packaging technology, reducing the number of connection points on the circuit board, improving the module's anti-interference ability and long-term stability.
However, the size is relatively large and is not suitable for small devices with limited space. It also cannot complete graphic conversion. The cost is high, especially for applications that require high display quality and stability.
1604COB LCD screen is widely used in calculators, industrial control panels, instruments, smart home devices and other fields. Its display effect is clear and suitable for displaying simple digital, text and other information.
Industrial Control: such as display screens of various instruments and automation equipment.
Communication Equipment: such as information display terminals, communication test equipment.
Consumer Electronics: such as POS machines, vending machines and other products that need to display a large amount of information.
4.Production process
Â
The process flow of manufacturing 1604 display screen includes:
LCD Panel Preparation: prepare the LCD glass substrate and coat it with liquid crystal material and electrodes.
COB Packaging: integrate the LCD panel, driver IC and control logic on a PCB circuit board and fix it through welding and other processes.
Backlight Assembly: add backlight source, usually LED backlight to provide sufficient brightness and uniformity.
Testing And Debugging: functional test and quality inspection of finished modules to ensure that all parameters meet the specifications.
Packaging: package the qualified modules and prepare them for shipment to customers or integration into the final product.
