LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode) display module production equipment are essential for the manufacturing of display devices used in a wide range of applications, from consumer electronics such as smartphones and televisions to industrial equipment and automotive displays. These equipments play a crucial role in ensuring the quality, performance, and reliability of the display modules, and their continuous innovation and development are driving the progress of the display technology industry.
Classification
1. Backplane Equipment
Array Test Equipment : It is used to test the array substrate in the LCD/OLED production process to detect defects such as open circuits, short circuits, and pixel defects. This helps to ensure the normal operation of the display pixels and improve the yield.
Deposition Equipment : For OLED production, deposition equipment is used to deposit organic materials on the substrate to form the emissive layer. In LCD production, it is also used for depositing materials such as indium tin oxide (ITO) for the electrodes. The quality and uniformity of the deposition process have a significant impact on the display performance.
Etching Equipment : Dry etching and wet etching equipment are used to remove unwanted materials in the production process, such as the etching of gate, source/drain, and ITO/IGZO layers in the backplane fabrication. This helps to define the patterns and structures of the circuit.
2. Frontplane Equipment
Evaporation Equipment : In OLED production, evaporation equipment is used to deposit the organic light-emitting materials in a precise and controlled manner. This is a critical process for achieving high-quality and uniform emission of the OLED pixels.
Film Thickness Measurement Equipment : It is used to measure the thickness of the various films in the frontplane, such as the organic layers in OLED and the color filter layers in LCD. Accurate film thickness measurement is important for ensuring the optical performance and color accuracy of the display.
3. Cell Equipment
LC Insertion Equipment : In LCD production, LC (Liquid Crystal) insertion equipment is used to inject the liquid crystal material into the cell. The precision and uniformity of the LC injection process affect the response time and image quality of the display.
Photo Alignment Equipment : It is used to align the liquid crystal molecules in a specific direction, which is crucial for the polarization and light control of the LCD. The photo alignment process needs to be highly precise to ensure the uniformity and stability of the liquid crystal alignment.
Bonding Equipment : This includes COF (Chip On Film)/COP (Chip On Plastic)/COG (Chip On Glass) bonding equipment, which is used to bond the driver ICs and other components to the display module. The bonding quality directly affects the electrical connection and reliability of the module.
Lamination Equipment : It is used to laminate the display panel with the touch screen, protective glass, and other components to form the final module. The lamination process needs to ensure the adhesion strength and optical performance of the module.
Conclusion
The LCD/OLED display module production equipment covers a wide range of categories, each playing a vital role in the manufacturing process. With the continuous development of display technology, these equipments are also constantly being upgraded and innovated to meet the increasing demands for higher resolution, better image quality, and more flexible display forms. The advancement of production equipment is an important driving force for the progress of the LCD/OLED display industry.
