3.5 Inspection Standards
Based on GB/T 2828-2003; normal inspection, Class II.
AQL for major and minor defect is specified in the full document.
3.5.1 Key Visual Inspection Criteria
- Black tape & Mara tape defects:
- FPC or H/S black tape shift: Reject if glue touches polarizer or IC is bare (minor defect).
- No black tape: Reject (major defect).
- Tape position mistake: Reject if not according to engineering drawing (minor defect).
- Mara tape defect: Reject if peels before pulling the protecting film (minor defect).
3.6 Design Notes from Documentation
- B/L Driver: The backlight driving condition is IF=60mA, Vf=2.8~3.3V.
- Mechanical: Tolerance of segments to edge of glass: ±0.26mm (General Tolerance). The FPC includes PI reinforcement with a total thickness of 0.30mm (FPC+PI). Yellow insulating tape is used for protection. An easy-tear sticker is provided for FPC handling. Conductive silver dots (银浆点) are noted for grounding.
- Housing: It is recommended that the housing visual area be at least 0.3mm smaller than the VA on each side. The housing foam window should be at least 0.6mm larger than the VA on each side. TP edge should not contact metal conductors to avoid ESD or short circuit risks.
- RoHS: All materials are compliant with RoHS and Halogen-Free standards.
4. Application Guidelines & Critical Notes
- Power Supply: The module requires a 2.8V power supply for VDD and 1.8V for IOVCC (as per pin definition). Ensure the power supply ripple is minimized.
- Interface: This module uses a standard MIPI (Mobile Industry Processor Interface) protocol. The host processor must be configured for this protocol.
- Backlight Driver (External): An external constant current driver is required to supply a typical current of 60mA at a forward voltage of 2.8V to 3.3V.
- Reset: A hardware reset pin (RESET, Pin 9) is provided for global reset.
- Handling Precautions: Handle the module with care to avoid damage to the glass or FPC. Ground yourself to prevent electrostatic discharge (ESD). This module uses C-MOS LSI drivers, so unused input terminals should be connected to Vdd or Vss.
- Protective Film: Remove the protective film slowly, keeping the removing direction approximately 30-degree from the panel surface under ESD control. The humidity of the working room should be kept over 50%RH to reduce the risk of static charge.
- ITO Pad Caution: The ITO pad area needs special careful caution as it could be easily corroded. Do not contact the ITO pad area with HCFC, Soldering flux, Chlorine, Sulfur, saliva or fingerprint. It is recommended to cover the ITO area with UV or silicon.
