3.8 Design Notes from Documentation
- B/L Driver: The backlight driving condition is IF=40mA, Vf=22.4V (TYP) for the 14-Chip White LED configuration.
- Mechanical: Tolerance of segments to edge of glass: ±0.2mm. Steel plate reinforcement (钢片补强 T=0.2) is included. The FPC includes PI reinforcement with a total thickness of 0.3mm (FPC+PI补强). Yellow insulating tape is used for protection. Conductive double-sided tape (T=0.05mm) is used. New in V2: 1.3mm double-sided foam tape (1.3mm双面泡棉胶).
- Housing: It is recommended that the housing visual area be at least 0.3mm smaller than the VA (Viewing Area) 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: RoHS compliance is expected.
4. Application Guidelines & Critical Notes
- Power Supply: The module requires a 2.8V (Typ.) power supply for VCC and 1.8V (Typ.) for IOVCC. Ensure the power supply ripple is minimized.
- Interface: This module uses a standard 4-Lane MIPI DSI 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 40mA at a forward voltage of 22.4V.
- Reset: A hardware reset pin (RESET, Pin 24) is provided. A low pulse of at least 10µs is required for a valid reset. It is necessary to wait 15msec after releasing NRESET before sending commands.
- Handling Precautions: Handle the module with care to avoid damage to the glass or FPC. Ground yourself to prevent electrostatic discharge (ESD).
