The module uses a 40-pin FPC connector for the MIPI interface and power. Key signals from the specification include:
| Pin No. | Symbol | I/O | Function |
|---|---|---|---|
| 20 | MIPI-3N | I | MIPI Data negative signal |

Note: The specification includes an image of the full connector pin assignment. Pins 1-19 are not shown in the provided text snippet but are documented in the full specification document. Power supply (VDD) and MIPI data/clock lanes (MIPI-0 to MIPI-2) are among the signals on those pins.
3.2.3 Reset Timing Characteristics
The specification defines the reset timing for the RESX signal, operating under VSS=0V, VDDI=1.65V to 3.6V, VCI=2.5V to 5.7V, Ta = -30°C to 70°C. Key timing parameters include:
- tRES: Minimum reset low pulse width (not explicitly defined in the text snippet, but implied by the timing diagram).
- tREST: Time required after reset before entering Initial Condition (Default for H/W Reset).
The timing diagram in the spec shows the relationship between the RESX pin, Normal Operation, Resetting, and Initial Condition states. The reset pulse must be shorter than 5us to trigger a reset (according to the diagram text).

4. Application Guidelines & Critical Notes
Intended Use
- High-brightness 10.1-inch industrial, medical, and outdoor display applications.
- Applications requiring a WXGA (800×1280) resolution display with a standard MIPI interface.
- Systems requiring an ultra-high luminance panel (1000 cd/m²) for direct sunlight readability.
- IPS technology with ALL viewing direction for superior color consistency at wide angles.
Critical Design Considerations
- Ultra-High Brightness (1000 cd/m² Typ): The defining feature of this module. The backlight driver must be designed to handle the high LED current required to achieve this luminance level. The module provides direct access to LED Anode (Pin 39) and Cathode (Pins 31, 32) for an external constant-current LED driver.
- MIPI Interface Configuration: The module uses a standard MIPI interface. The host processor must be configured for the correct WXGA (800×1280) resolution and MIPI data lane count (the spec shows MIPI-0 to MIPI-3, indicating 4 data lanes).
- Wide Operating Temperature Range: With an operating range of -30°C to +70°C and a storage range of -35°C to +75°C, this module is suitable for demanding outdoor and industrial environments.
- External Backlight Driver Required: The module provides direct connections to the LED strings via LED+ and LED- pins. The module does not contain an integrated backlight driver. An external constant-current LED driver IC must be used.
- IPS Technology (ALL Viewing Direction): The “ALL” viewing direction specification, combined with IPS technology, ensures wide, consistent viewing angles with minimal color shift — critical for public displays or multi-user applications.
- Anti-Glare Surface Treatment: The Anti-Glare surface reduces reflections and improves readability in bright ambient light, complementing the high luminance for outdoor use.
- Reset Timing: The RESET signal must adhere to the defined timing characteristics (tRES, tREST) from the specification. The reset pulse width should be shorter than 5us to initiate a hardware reset.
- Power Voltage (VDD): The module requires a power supply (VDD) within the absolute maximum range of -0.3V to 5.0V. The typical operating voltage can be inferred to be within this range, typically 3.3V for MIPI modules.
- Image Sticking: An image sticking test is performed at 25°C ± 2°C with a static pattern for 2 hours. The mura should disappear within 5 minutes after switching to a gray pattern. This is a standard quality assurance test.
Handling & Compliance
- Observe standard ESD precautions during handling and assembly. The module is tested to ±4KV (Contact) and ±8KV (Air) per IEC61000-4-2.
- The module contains fragile glass and a precision FPC – handle with care.
- Avoid bending the FPC sharply, especially near the connector interface or glass edge.
- Do not attempt to disassemble or modify the LCD module.
- All NC (No Connection) pins should be left open to avoid interference.
- If the logic circuit power is off, do not apply input signals to avoid latch-up.
5. Conclusion & Design-In Support
The LS101I29-MP-V1 specification details a high-performance, ultra-high-brightness 10.1-inch IPS TFT display module with a standard MIPI interface, wide temperature range, and Anti-Glare surface treatment — an outstanding choice for demanding outdoor, industrial, and medical display applications.
Key Strengths
- Ultra-High Brightness (1000 cd/m² Typ): Ideal for direct sunlight readability and high-ambient-light environments.
- IPS Technology (ALL Viewing Direction): Superior wide-angle viewing with excellent color consistency.
- Extremely Wide Operating Temperature (-30°C to +70°C): Suitable for harsh industrial and outdoor climates.
- Anti-Glare Surface: Reduces reflections for improved visibility in bright conditions.
- Standard MIPI Interface: Simple connection to common mobile and embedded processors.
Main Design Focus
- The critical design tasks are selecting and designing a high-power external constant-current LED backlight driver to power the panel to its rated 1000 cd/m² luminance, and configuring the host’s MIPI DSI transmitter for a 4-lane, WXGA (800×1280) configuration.
- Supporting requirements: Provide a stable power supply (VDD, typically 3.3V). Follow the reset timing diagram for the RESX pin. Design the system enclosure to accommodate the module outline dimensions (143.06 x 228.66 x 4.00 mm).
This module is a premium choice for engineers requiring a rugged, sunlight-readable, 10.1-inch display with IPS viewing angles and a robust MIPI interface.
