4Lane x 2port. This could support higher refresh rates or a different data partitioning scheme. - Specific Driver IC: Uses dual R69429 COG driver ICs, providing a concrete component for host initialization sequence development.
- Optical Targets: Lists Contrast Ratio as (1200) and NTSC as (72%), which are slightly different from the I01's 1000:1 and 77.1%. These may be target specs, represent different measurement conditions, or indicate a different panel batch.
- Active Area: 236.0 x 148.0 mm vs. I01's 234.0 x 148.0 mm. This minor discrepancy could be due to different panel sourcing or measurement methodologies.
- Environmental Specs: Explicitly lists operating and storage temperature ranges.
Relationship between I01 and I02: They are two versions or specifications of the same core 11.0" WQXGA LTPS platform. I02 likely represents a later revision with updated driver ICs and a refined interface specification, or it could be a variant tailored for a specific customer or performance profile (e.g., targeting higher contrast).

3.2 Electrical & Interface
- Power Supply: Not detailed in snippets, but typical for high-resolution LTPS modules includes multiple rails: VDD (1.8V/3.3V), AVDD (~5-12V), VGH/VGL (+15V to +25V / -5V to -15V).
- Dominant Interface: MIPI DSI in a high-lane-count, dual-port configuration. This is mandatory to handle the data rate.
- Data Rate Estimate: For 2560x1600 @ 60Hz, 24bpp, the raw data rate is ~ 7.68 Gbps. An 8-lane MIPI interface (I02) would require ~960 Mbps per lane, which is within the capability of MIPI D-PHY v1.2.
- Backlight: Uses an array of LEDs (30 for I01). Constant current driving is essential for stable brightness and LED longevity.
4. Mechanical Specifications
- Active Area (AA): Approximately 234.0 x 148.0 mm (I01) or 236.0 x 148.0 mm (I02). The 16:10 aspect ratio offers more vertical space than 16:9, beneficial for productivity and document viewing.
- Module Dimensions (I01): 244.3 x 160.1 x 2.1 mm (excluding FPC and Cover Glass). This indicates a design with slim bezels and a very thin profile.
- FOG Size (I02): 242.60 x 156.60 mm, closely matching the I01 module size, suggesting it's the core panel assembly.
- Thickness: The panel glass is 0.25mm thick (I02), contributing to the overall slim module design.
5. Application Scenarios

6. Integration Notes & Critical Considerations
1. High-Speed Signal Integrity:
- The MIPI DSI interface with 4 or 8 data lanes operates at high speeds (>500 Mbps per lane). This demands careful PCB layout:
- Length Matching for all differential pairs (within 5-10 mil tolerance).
- Controlled Impedance (100Ω differential).
- Minimal layer transitions and vias.
- Adequate separation from noise sources (switching regulators, clocks).
2. Complex Power Management:
- High-resolution LTPS panels require multiple, precisely sequenced power rails. The power-on/off sequence specified in the full document must be strictly followed to prevent latch-up or permanent damage to the panel.
3. Thermal Management:
- Driving over 4 million pixels and a backlight generates heat. The host product must have adequate thermal design, especially if the module is used at high brightness or in high ambient temperatures, to ensure reliability and prevent brightness dimming.
4. Driver IC Initialization:
- The use of specific driver ICs (R69429 for I02) means the host's MIPI command set and initialization sequence must be compatible. The full specification should provide the required initialization code (init code).
5. Mechanical and Optical Integration:
- The document for I02 references "HANDLING PRECAUTIONS," which will contain critical information on ESD protection, avoidance of mechanical stress, and cleaning procedures.
- For best optical performance and ruggedness, especially in mobile applications, bonding the module to a cover glass using OCA (Optically Clear Adhesive) is highly recommended.
Conclusion: The LESSON 11.0-inch series (LS110I01/02-MP-V1) represents a top-tier display solution for applications demanding the highest levels of clarity and color performance in a compact form factor. It sits at the intersection of cutting-edge panel technology (LTPS-IPS) and high-bandwidth digital interfaces (MIPI), making it a compelling choice for designers of premium consumer electronics and professional tools.
