Custom LED Backlights

Custom LED backlights developed to match the LCD size, brightness, colour, thickness, illumination structure and electrical requirements of the application.

LED backlights improve LCD readability in indoor, outdoor and low-light conditions. Each backlight is developed around the LCD size, the enclosure and the application requirement, with uniform illumination and long service life in mind.

Available configurations include edge-lit and direct-lit structures, multiple colours, brightness levels and thicknesses, with customised electrical arrangements. Development is confirmed against an approved project specification before sampling.

Typical Applications

Custom Development Process

  1. 1 Share drawing or requirement

    Send a drawing, sample, or a description of the display you need.

  2. 2 Technical review

    Our engineering team reviews the layout, dimensions, and operating conditions.

  3. 3 Specification confirmation

    Display mode, viewing direction, polarizer, backlight, and interface are agreed in writing.

  4. 4 Sample development

    Samples are developed to the confirmed specification.

  5. 5 Evaluation and approval

    You evaluate the sample in the product and confirm approval.

  6. 6 Production and inspection

    Approved parts move to production with inspection and batch records.

Quality and Testing

Incoming Inspection

Incoming materials are inspected before assembly.

Brightness and Uniformity

Backlight brightness and uniformity are checked across the viewing area.

Assembly Matching

Each backlight is matched to the LCD module during assembly.

Final Verification and Traceability

Visual inspection against the approved sample, final inspection, batch records and traceability.
