3.4 Quality Inspection Standards

The specification includes detailed Acceptance Quality Level (AQL) criteria based on GB/T 2828-2003.

A. Appearance Defect Criteria (Examples):

  • Cracks (Major): Linear cracks on panel lead to rejection.
  • Glass Extrusion (Minor): Accepted if extrusion width ≤ 1/3 of pin width in non-bonding area, or ≤ 0.5mm in bonding area.
  • Conductive Area Damage (Minor): Accepted if damage width ≤ 1/3 of effective bonding electrode length.
  • Non-Conductive Area Damage (Minor): Accepted if damage doesn't touch ITO, or if depth < thickness and width ≤ 1/3 of BM width.

B. Electrical Defect Criteria (Major - All lead to Rejection):

  1. No display.
  2. Missing line.
  3. Segment/common electrode light and dark不均 (tested with ND filter 2%).

4. Application Guidelines & Critical Notes

  • Intended Use: High-resolution compact devices, wearables, advanced HMIs, medical imaging previews—applications requiring a sharp, square, high-color-depth display with a high-speed serial interface.
  • Critical Design Considerations:
    1. MIPI DSI Host Required: This module requires a host processor or GPU with a MIPI DSI transmitter. It is not compatible with SPI, parallel RGB, or other simple interfaces.
    2. Dual Power Supplies: Provide clean, stable VDD2.8V (2.8V) for the display core and IOVCC1.8V (1.8V) for the I/O and MIPI interface. Ensure they are within the absolute maximum ratings.
    3. Signal Integrity: The MIPI differential pairs (D0P/N, CP/CN) require controlled impedance (100Ω differential) on the host PCB, with careful length matching and routing away from noise sources.
    4. Backlight Drive: Design a constant-current driver for the backlight LEDs (60mA typical, Vf 2.8-3.3V).
    5. Reset Circuit: Use the RESET pin for proper initialization. Timing should follow the driver IC (ST7797) requirements.
    6. Industrial Temperature: Designed for -10°C to +70°C operation, suitable for many industrial environments.
    7. Quality Assurance: Use the provided inspection criteria as a guideline for incoming quality checks.
  • Handling & Compliance: The module uses RoHS and Halogen-Free compliant materials. Observe stringent ESD precautions, especially around the MIPI lines and fine-pitch FPC.

The LS016I03-MP-V1 specification presents a high-performance 1.6-inch square MIPI DSI display module. Its standout features are the unusual and sharp 400x400 square resolution, support for 16.7 million colors, and the modern MIPI DSI interface enabling high-speed data transfer with low EMI. The inclusion of detailed industrial-grade inspection standards underscores its suitability for quality-critical applications. The main design challenge is implementing a MIPI DSI source and ensuring signal integrity for the high-speed differential lines. This module is an excellent choice for cutting-edge portable devices where a premium, high-resolution small display is needed.
