Product Definition
The 3D Curved Screen Module is a product composed of multiple materials including a substrate and light source devices. These components work together to achieve the unique functionality and outstanding visual effects of the 3D curved screen. Each display unit can be individually controlled for color and brightness, collectively forming various display images, text, animations, and more.
· Functional Substrate: The carrier for LED display components, a flexible printed circuit board made of polyimide or other flexible materials.
· Light Source Devices on Substrate: The core component that determines the display quality and performance of the screen, typically Cold Cathode Fluorescent Lamps (CCFL) or Light Emitting Diodes (LEDs).
· Substrate Driver IC and Circuitry (Optional): Responsible for controlling the arrangement of light sources and the operation of backlighting.
· Substrate Connector (Optional): Ensures signal transmission between the screen and external devices.
· Light-Guiding Bracket: Divides the display into regions based on the light source display logic, performing light-blocking or light-guiding functions.
· Graphic Overlay Film: Features light-transmitting and light-shielding properties, produced through printed ink.
· Lamination & Encapsulation Material: Adhesive for lamination.
Curved Screen Module Functional Substrate Process: Material cutting, drilling, pattern transfer, etching, lamination, testing, assembly, and other processes. Key points: material selection, solder mask process, etching process.
Substrate FPCBA Process: Programmed loading, stencil, solder paste printing, SMT placement, die bonding, AOI (Automated Optical Inspection), reflow soldering, inspection and testing, and other processes. Key points: stencil aperture design, reflow soldering process.
Light-Guiding Bracket Process: Material cutting, programmed loading, die cutting, and other processes.
