4. Application Guidelines & Critical Notes

Intended Use

• High-resolution portable displays
• Industrial handheld devices
• Medical instruments
• Any application requiring a compact, high-resolution display with excellent image quality

Critical Design Considerations

1. LVDS Interface:

   • This module uses an LVDS (Low Voltage Differential Signaling) interface for high-speed data transmission.
   • The host system must have an LVDS transmitter to drive the display.
   • Proper differential trace routing (impedance control, length matching) is critical for signal integrity.

2. Power Supply:

   • Provide stable VCC (3.0V to 3.6V, 3.3V typical) for the main logic.
   • Provide stable IOVCC (2.85V to 3.6V, 3.3V typical) for the I/O interface.
   • The module has multiple ground pins (GND) for noise reduction.

3. Mechanical Integration:

   • Module Outline: 62.5mm (W) × TBD × 1.3±0.2mm (D).
   • Active Area: 59.52mm (H) × TBD (V).
   • FPC: The module uses a multi-pin FPC with a specific pitch.
   • Enclosure Design: The document provides specific recommendations for enclosure window openings relative to the LCD AA (Active Area):
     • Housing visible area: 0.3mm smaller per side than VAmds.
     • Housing foam window: 0.6mm larger per side than VAmds.
     • TP edge cannot contact metal conductors.
