4. Application Guidelines & Critical Notes
Intended Use
- Embedded display applications requiring an 8.8-inch screen with a portrait-oriented, ultra-wide (480×1920) resolution.
- Industrial control panels, medical devices, POS systems, and other applications needing a long, narrow display format.
- Applications requiring a standard 4-lane MIPI DSI interface.
Critical Design Considerations
- Unusual Aspect Ratio: The 480×1920 resolution is a portrait-oriented ultra-wide format (1:4 aspect ratio), ideal for displaying long lists, timelines, or narrow control panels. The host graphics system must support this non-standard resolution.
- Multi-Voltage Power Supply: The module requires multiple voltage rails: VDD (3.3V typical), VCI (2.8V typical), and IOVCC (1.8V typical). Additionally, internal charge pump voltages VGH (up to 26V), VGL (as low as -11.5V), and AVDD (up to 12.5V) are generated internally, but the absolute maximum ratings must be respected.
- Backlight Driving: The backlight requires a constant current driver with a typical current of I_L = 160mA and a forward voltage of V_L = 16V (Typ.), up to 17.5V (Max.). Individual LED forward current is limited to 80mA.
- MIPI Termination Resistors: The module has embedded termination resistors (R_T) with a default value of 100 ohms. This means external termination resistors on the PCB are not required, but the host must ensure the TERMR_EN bit is enabled in the display's register settings.
- Operating Temperature Range: The module supports a wide industrial temperature range: -20°C to +70°C (operating) and -30°C to +80°C (storage).
- Connector Recommendation: The specification explicitly recommends the Hirose FH34SRJ-40S-0.5SH(50) connector. It is critical to use this exact model for mechanical compatibility.
- Standby Mode: Pin 23 (STBYB) is provided for standby mode control, allowing for power saving when the display is not in use.
- Touch Panel Sync: Pin 24 (TP_Sync) provides a synchronization signal for an external touch panel controller, simplifying system integration.
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 to avoid damage.
- Avoid bending the FPC sharply, especially near the connector interface.
- Do not attempt to disassemble or process the LCD Module.
- Ensure all NC (No Connect) pins are left open.
5. Conclusion & Design-In Support
The LS088I01-MP-V1 specification details a unique 8.8-inch TFT-LCD module with an ultra-wide portrait resolution (480×1920), a standard 4-lane MIPI DSI interface, embedded termination resistors, and a wide operating temperature range — an excellent choice for applications requiring a long, narrow display.
Key Strengths
- Unique 480×1920 Resolution: Ideal for portrait-oriented, ultra-wide format applications.
- Wide Operating Temperature: Suitable for industrial and outdoor environments (-20°C to +70°C).
- Embedded MIPI Termination: Simplifies PCB layout by removing the need for external termination resistors on the data and clock lines.
- Integrated Touch Sync: Includes a dedicated sync signal for touch panel controllers.
- Standard MIPI Interface: 4-lane MIPI DSI is a widely supported interface.
Main Design Focus
- The critical design task is ensuring the host processor can output the non-standard 480×1920 resolution over its MIPI DSI interface.
- Supporting requirements: Design a multi-rail power supply (3.3V, 2.8V, 1.8V) and a constant current backlight driver (160mA @ 16V). Ensure the host MIPI controller is configured not to use external termination resistors. Use the recommended Hirose FH34SRJ-40S-0.5SH(50) connector.
This module is an excellent choice for applications requiring a long, narrow 8.8-inch display with a standard MIPI interface and industrial temperature range.
