The manufacturing process of a mobile phone screen is highly precise and complex, involving multiple stages such as raw material preparation, special technical processing, automated production, rigorous quality inspection, and module manufacturing.
1. Raw Material Preparation
Mobile phone screen production begins with raw material preparation. For OLED screens, organic light-emitting materials such as red, green, and blue light-emitting materials are required. These materials are the foundation of screen light emission and are crucial for the screen's color performance and brightness.
2. Special Technical Processing
In the production of eye-protection screens, special technologies are employed to reduce the impact of harmful blue light. For example, by shifting the peak position of harmful blue light in the OLED spectrum and combining it with high-frequency PWM dimming and DC dimming technologies, the screen's eye-protection effect is enhanced. These technologies can significantly reduce screen damage to the eyes and improve the user's visual experience.
3. Automated Production
Mobile phone screen production lines are highly automated and intelligent. From material handling to manufacturing processes, everything is automated. For example, Tianma Wuhan's TM17 production line covers multiple product lines, including mobile phones, IT displays, and automotive displays, using cutting-edge technology in the industry to ensure that the produced screens are of high quality.
4. Rigorous Quality Inspection
Screens undergo rigorous testing during production. Using AVT (Automatic Visual Inspection) equipment, the screen is photographed with high precision from multiple angles, and combined with algorithmic models, defects such as tiny dead pixels or uneven brightness are automatically identified. These inspection methods ensure that every screen displays fine image quality and uniform brightness.
5. Module Manufacturing Process
Mobile phone screen production also includes module manufacturing processes, such as color compensation. These processes ensure better image quality in low-brightness conditions, further enhancing the consumer experience.
