1. Glass Cutting and Cleaning: Raw glass substrates are cut to size and cleaned in an ultrasonic bath. 2. COG (Chip-on-Glass) Bonding: The ST7735 driver IC is bonded directly to the glass using anisotropic conductive film (ACF). 3. FPC Attachment: A flexible printed circuit (FPC) is bonded to the glass for electrical connection. 4. Backlight Assembly: A white LED backlight is attached. 5. Module Assembly: The display cell, backlight, and FPC are laminated together. 6. Aging and Testing: Modules undergo a 24-hour burn-in and a full electrical and visual inspection. 7. Final Quality Check: Each unit is tested for color uniformity, pixel defects, and SPI communication.

What Quality Certifications and Testing Do We Follow?

We adhere to rigorous international standards to ensure every ST7735 TFT LCD module meets your expectations. Our factory holds ISO 9001:2015 certification, and our products comply with RoHS and REACH directives.

  • ISO 9001:2015 - Quality Management System
  • RoHS - Restriction of Hazardous Substances
  • REACH - Registration, Evaluation, Authorization and Restriction of Chemicals

Our testing protocol includes: 100% visual inspection for pixel and dust defects, electrical parameter verification (VDD, IDD, contrast), SPI communication test at maximum clock speed, and a 24-hour aging test under elevated temperature (60°C). Each module is individually tested before packaging.

What Logistics and Customization Options Are Available?

We understand that global sourcing requires flexibility. Our standard ST7735 TFT LCD modules are available in 1.44-inch and 1.8-inch sizes with white backlight and standard pinout. For volume orders, we offer customization.

  • Minimum Order Quantity (MOQ): 100 units for standard models; 1000 units for custom designs (e.g., custom FPC length, pinout, or backlight color).
  • Lead Time: 7-10 business days for standard orders; 3-4 weeks for custom orders (subject to order volume and complexity).
  • Shipping: We partner with DHL, FedEx, and UPS for express delivery (3-5 days to most destinations). For sea freight, contact our logistics team for a quote.
  • Tariff and Customs Support: We provide all necessary documentation, including commercial invoices, packing lists, and certificates of origin, to facilitate smooth customs clearance. Our team can advise on HS codes (typically 9013.80 or 8531.20) and potential duties for your region.

For buyers in the Middle East and Southeast Asia, we can arrange L/C (Letter of Credit) payments for orders above USD 10,000.

How to Select the Right ST7735 TFT LCD for Your Application?

Choosing the correct module depends on your specific needs. Here is a simple decision framework:

  • Resolution and Size: For simple icons and text, the 1.44-inch (128x128) is sufficient. For more detailed graphics or data, choose the 1.8-inch (160x128).
  • Interface: Ensure your microcontroller supports SPI. We provide example code for Arduino, STM32, and ESP32.
  • Backlight: Standard white is suitable for most indoor uses. For outdoor applications, consider a higher brightness variant (contact us for details).
  • Operating Temperature: Our standard range (-20°C to +70°C) covers most commercial and industrial environments. For extreme conditions, request our extended temperature version.
