4. Application Guidelines & Critical Notes
Intended Use
- Embedded display applications requiring an 8.0-inch TFT screen with a standard MIPI DSI interface.
- Tablets, portable devices, and industrial control panels requiring 800×1280 resolution.
Critical Design Considerations
- MIPI DSI Interface: The module requires a 4-lane MIPI DSI connection from the host processor. Ensure the host's MIPI DSI transmitter is configured for 4 lanes and meets the typical MIPI D-PHY electrical levels (VOH ≈ 1.2V, VOL < 50mV, output impedance ZOLP ≥ 110Ω).
- Backlight Driving (Dual Core): The module uses a Dual Core LED configuration (two sets of LED strings). The total current is IF = 140 mA and the total voltage is VF = 16.8V to 19.2V. Design a constant current LED driver that can handle this combined load. An example calculation from the back of the drawing suggests IF per core = 70 mA, VF total = 2 * (LED chip VF) depending on the series configuration.
- Mechanical Mounting:
- The drawing notes that the FPC is shipped in a bent 90° position.
- The module uses double-sided conductive tape (T=0.1mm) for ESD grounding and silver paste points for additional ground contact.
- A T=0.2mm steel reinforcement plate is used on the back of the FPC connector area to provide rigidity.
- ESD Protection: Follow the silver paste point and conductive tape landing patterns carefully to ensure proper ESD grounding.
- Tolerance: Outline dimension tolerances are: ±0.2mm for 2 decimal places, ±0.3mm for single decimal places.
Handling & Compliance
- The module is produced by Lesson Smart Display Technology Co., Ltd. and is likely ROHS compliant.
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass and a precision FPC – handle with care.
- Do not attempt to disassemble or modify the LCD module.
- NC (No Connect) pins should remain open.
