Large-Size Backlight Customization High Brightness

1. Requirements Research and Solution Design Phase

First, we engage in in-depth communication with the customer to clarify the core requirements for the Large-Size High-Brightness Backlight Customization, including key indicators such as size specifications, brightness parameters, color temperature, color rendering index, structural requirements, installation environment, service life, and protection level. Based on these requirements, we design a solution, including light source selection (determining the LED bead model, quantity, and arrangement), optical structure design (optical film combination, light guide plate structure design), drive circuit design, and heat dissipation structure design. We then complete the drawing of the solution diagrams and conduct feasibility verification.

2. Raw Material Procurement and Inspection Phase

Based on the design solution, we procure core raw materials, including high-brightness LED beads, light guide plates, diffusion films, brightening films, driver chips, PCB boards, heat dissipation materials, and casing materials. All raw materials undergo strict inspection, focusing on the brightness and color temperature consistency of the LED beads, the light transmittance of the optical films, and the circuit integrity of the PCB boards, ensuring that the raw materials meet the design standards and preventing product performance issues due to raw material problems.

3. Core Component Processing and Assembly Phase

First, we process the core components, including circuit printing and welding of the PCB board (welding LED beads, driver chips, and other components to the PCB board), cutting and engraving of the light guide plate (cutting the light guide plate according to size requirements and engraving light guide points to optimize light diffusion), and processing and forming of the heat dissipation structure. Then, we proceed to the assembly stage, installing the light guide plate, optical films, LED light board, heat dissipation components, and casing in the designed order, ensuring that all components are tightly fitted, the optical path is smooth, and the drive circuit is properly connected.

4. Debugging and Testing Phase

The assembled Large-Size High-Brightness Backlight Customization product undergoes power-on debugging, adjusting the drive circuit parameters to ensure that brightness, color temperature, and other indicators meet customer requirements. Then, a comprehensive test is conducted, including brightness uniformity testing, brightness stability testing, energy consumption testing, protection level testing, and aging testing (simulating long-term use environment to test product stability). Products that pass the tests proceed to the next stage; unqualified products are returned for rework and retesting.

5. Packaging and Shipping Phase

The qualified products are professionally packaged using anti-static and shock-proof packaging materials to prevent damage during transportation. We will also include product specifications, test reports, and other relevant documents, and arrange shipment according to customer requirements to ensure that the products are delivered safely and on time.
