Complete Smartphone LCD Production Line: From Module Assembly to Final Testing.
In the highly competitive electronics market, establishing a high-efficiency, high-yield Smartphone LCD Production Line is the key to success for manufacturers. As smartphones evolve towards full-screen designs, higher resolutions, and flexible displays, the assembly process has become increasingly complex.
Shenzhen Olian Automatic Equipment Co., Ltd., a national high-tech enterprise based in Shenzhen, China, offers a comprehensive suite of automation solutions designed to cover the entire process of smartphone display module manufacturing.
From the initial ACF attachment to the final backlight assembling, our equipment is engineered to meet the stringent requirements of modern smartphone production.
🏗️ The Architecture of a Modern Smartphone LCD Line
A standard production line for smartphone LCDs typically consists of three major stages: Front-End Bonding,dispensing,AOI Testing.Backlight Assembly,
1. Front-End Bonding: The Core of Electrical Connection
This stage establishes the critical electrical connection between the display panel and the driver IC/FPC.
ACF Attachment Machine: Before bonding, Anisotropic Conductive Film (ACF) must be precisely applied. Our machines use a precision dispensing or tape attachment system to ensure the ACF is placed accurately on the glass or film without wrinkles or static, which is vital for preventing open circuits.
COG (Chip on Glass) COF(COF(chip on film) on glass) COP(Chip on Plastic) Bonding Machine: This is where the heart of the display, the Driver IC, is bonded directly onto the glass substrate.Engineering Highlight: Our OL-1000 Series COG bonder utilizes a constant temperature method with a temperature control range of 0°C to 399°C.
It achieves an industry-leading accuracy of ±3μm,
ensuring the tiny bumps on the IC align perfectly with the ITO electrodes on the glass.
FOG (Film/FPC on Glass) / FOF (Film on Film) Bonding Machine: Following the IC bonding, the FPC (Flexible Printed Circuit) is connected. For smartphones utilizing in-cell touch technology, this is often a FOG process. For flexible OLED or traditional capacitive touch panels, it may involve FOF bonding. Our equipment features a unique “convex silicone belt” design to handle the uneven surfaces of double-layer films, ensuring uniform pressure and preventing “pulling glue” defects.
2. Mid-End Assembly: Module Integration
Once the electrical connections are secure, the display must be integrated into the final module structure.
FPC Cutting & Bending Machine: After bonding, excess FPC material must be removed, and the FPC must be bent to a specific angle (90° or 180°) to fit inside the smartphone chassis. Our precision die-cutting and bending machines ensure clean cuts without burrs and precise bending angles without damaging the copper traces.
OCA Laminating & Pressing Machine: For full-lamination smartphones, Optical Clear Adhesive (OCA) or Optically Clear Resin (OCR) is used to bond the cover lens (Glass) to the display panel (LCD/OLED). This process requires a dust-free environment and precise vacuum lamination to eliminate bubbles.
IR Oven / UV Curing Machine: After lamination, the adhesive must be cured. We provide IR tunnel ovens and UV curing systems that ensure the adhesive reaches its maximum bonding strength without damaging the polarizer or the LCD liquid crystal.
No smartphone LCD line is complete without rigorous testing.
Electrical Testing (ICT/FCT): Automated test fixtures verify that every pixel, touch sensor, and communication line is functioning correctly.
Aging Test Chamber: Modules are subjected to high temperatures and continuous operation to simulate long-term use. This “burn-in” process weeds out early-life failure units before they reach the consumer.
