This is the flagship model described in detail, featuring unique dual-mode display capability.

• Core Specifications:

  Item	Specification	Unit	Remark
  Resolution	720(H)*3(RGB)*1440(V)	Dots
  Interface	MIPI	-	4 Lanes
  Module Power (Reflective)	0.146	Watt	Typical
  Module Power (Transmissive)	0.986	Watt	Typical
  Luminance (Reflective)	8.5% * Surrounding illumination	cd/m²	Uses ambient light
  Luminance (Transmissive)	80 + 8.5% * Surrounding illumination	cd/m²	Backlight ON

  Interface	4 Lane MIPI	-	LS055I01-MP-V1
  Driver IC	XM91080 (COG)	-	LS055I01-MP-V1
  Driver IC	GT911 (Multi-touch)	-	LSC055I16-MP-V1 (with CTP)
  Backlight	14 pcs White LED	-	If=40mA, Vf≈22.4V

• Key Features:

  • High Resolution: 1080*1920 resolution for detailed imagery.
  • High Integration: The LSC055I16-MP-V1 integrates a touch panel (CTP) with G+F+F structure, Asahi Glass cover lens with surface hardness ≥6H.

Model: LS055I06-MP-V1 (HD Series)

A classic transmissive HD display module.

• Core Specifications:

  Item	Specification
  Resolution	720(RGB)*1280
  Type	Transmissive a-Si TFT-LCD

3. Mechanical Structure & Drawing Example

All 5.5-inch modules must adhere to strict mechanical design rules. The following points and example drawing (conceptual based on description) are crucial for integration design.

Critical Design Notes:

1. Bezel Opening Recommendation: The case lens opening should be >0.3mm larger per side than the LCD Active Area (AA) to avoid cropping.
2. Sponge Gasket Opening: The internal sponge gasket opening should be >0.6mm larger per side than the AA to avoid pressure on the display.
3. FPC Bending: Pay attention to FPC bend radius and stress. A pre-bent design is often used.
4. Grounding & Insulation: The steel stiffener on FPC usually needs grounding and proper insulation from surrounding metal parts.
5. Unspecified Tolerance: Dimensions without noted tolerance typically follow ±0.2mm.

• Typical Dimension Reference (e.g., LSC055I16-MP-V1):
  • LCM Size (W×H): ~70.8 mm × ~141.8 mm (varies by model)
  • AA Size: 68.04 mm × (depends on resolution)
  • Module Thickness: Typically ~1.5mm - 3.0mm (thicker for versions with CTP).

4. Electrical & Optical Characteristics Summary

• Supply Voltages: Logic (IOVCC) typically 1.8V or 3.3V; Panel drive (VCI/VDD) may be 2.8V or 3.3V; Backlight (LEDA) varies from 3V to 24V depending on LED series count.
• Power Consumption: Varies significantly. The dual-mode module uses only 0.146W in reflective mode and ~0.986W in transmissive mode. Higher-resolution FHD+ modules consume more power.
• Optical Performance:
  • Luminance: Transmissive modules typically 300-500 cd/m², adjustable via backlight current.
  • Contrast Ratio: Usually > 1000:1.
  • Viewing Angle: Models with IPS or ALL FREE technology offer wide viewing angles, often >80 degrees in all directions.
