- Display On: Send Display On command (0x29). Send Sleep Out command (0x11). Wait 100ms.
- Backlight On: Turn on the backlight last.

4. Application Guidelines & Critical Notes
Intended Use
- High-resolution embedded display applications requiring an 8.9-inch screen with a dual-channel MIPI DSI interface.
- Tablets, portable devices, and industrial control panels requiring 2560×1600 WQXGA resolution.
- Applications requiring a 16:10 aspect ratio display with Wide View angle technology.
Critical Design Considerations
- Dual MIPI DSI Interface: This module uses a unique dual MIPI DSI configuration: Left DSI (pins 10-24, with data lanes 0, 1, 2, 3 and clock) and Right DSI (pins 30-31, with only data lane 2). This is a high-resolution split-screen configuration. The host processor must support dual MIPI DSI channels and route the data lanes accordingly.
- Multi-Voltage Power Supply: Unlike many modules, this requires three distinct external power supplies: IOVCC (1.8V), VSP (5.4V), and VSN (-5.4V). A triple-output power regulator is needed. Additionally, DPHYVCC must be connected to IOVCC.
- Critical Power Sequence: The specified power-on sequence is mandatory: IOVCC → 5ms → VSP → 8ms → VSN → 10ms → RESET (with specific timing) → 200ms → MIPI commands → 100ms → Display On/Sleep Out → 100ms → Backlight.
- Backlight Driving: The backlight uses 30 White LEDs with a forward current of IF = 120mA and forward voltage of VF = 14-16V. A constant current LED driver is required.
- High Resolution (2560×1600): Each MIPI data lane must operate at a high data rate to support 2560×1600@60Hz. Ensure the host MIPI transmitter is capable of the required bit rate.
- Wide View Angle: The module specifies \"Wide View\" as the viewing angle, providing consistent color and contrast across a wide range of viewing positions.
- Temperature Limits: Operating Temperature: 0°C to +50°C. Storage Temperature: -20°C to +60°C. This is a narrower operating range compared to many industrial modules.
- Cross Talk Performance: The spec includes a specific test methodology for Cross Talk (CT), indicating that image quality (specifically related to crosstalk) is a characterized parameter.
Handling & Compliance
- The module is ROHS Compliant.
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass and FPC – handle with care.
- Avoid bending the FPC sharply, especially near the connector interface.
- Do not attempt to disassemble or process the LCD Module.
- NC terminals should be open. Do not connect anything.
- If the logic circuit power is off, do not apply the input signals.
5. Conclusion & Design-In Support
The LS089I01-MP-V1 specification details a high-resolution 8.9-inch WQXGA (2560×1600) TFT-LCD module with a unique dual MIPI DSI interface, 16:10 aspect ratio, triple-voltage power supply (IOVCC/VSP/VSN), 300 cd/m² typical luminance, and Wide View angle — an excellent choice for applications requiring a large, high-resolution display with a split-screen MIPI interface.
Key Strengths
- High Resolution (2560×1600 WQXGA): Exceptional image clarity and detail for an 8.9-inch display.
- 16:10 Aspect Ratio: Suitable for productivity and multimedia applications.
- Wide View Angle: Good viewing angle performance.
- Standard 300 cd/m² Luminance: Suitable for indoor use.
- Detailed MIPI AC Specs: Clear requirements for D-PHY HS and LP signaling.
Main Design Focus
- The critical design task is designing a power supply system capable of generating three stable voltages (IOVCC=1.8V, VSP=5.4V, VSN=-5.4V) and implementing the precise power-on sequence.
- Supporting requirements: Configure the host's dual MIPI DSI transmitter to match the module's lane mapping (Left DSI: lanes 0-3 + clock; Right DSI: lane 2 only). Design a constant current backlight driver rated for 120mA at 14-16V. Adhere strictly to the power-on sequence.
This module is an excellent choice for applications requiring a high-resolution 8.9-inch display with a non-standard dual MIPI interface and triple-voltage power supply.
