3. Mechanical & Physical Characteristics
Common Mechanical Parameters (Varies by model):
- Panel Size: 7.0 inches (diagonal, approximately 154.0mm × 85.9mm, depending on aspect ratio)
- Module Thickness: Typical range from 3.0mm to 6.0mm, models with integrated CTP are thicker.
- Active Display Area (AA): Varies by resolution:
- 800×480: Approximately 152.4mm (W) × 91.44mm (H) or similar ratio.
- 1024×600: Approximately 154.08mm (W) × 85.92mm (H) or similar ratio (16:9).
- Connector: Typically uses FPC (Flexible Printed Circuit) connection, common pin pitch is 0.5mm or 1.0mm.
- Mounting Method: Modules usually feature mounting holes or snap-fit structures around the perimeter for secure fixation within the housing.
Mechanical Design Considerations (Based on common spec requirements):
- Bezel Opening Design: The housing's display window should be at least 0.3mm larger than the LCD's AA area on each side to ensure no obstruction.
- Gasket/Sponge: The opening of the cushioning/sealing sponge should be at least 0.6mm larger than the AA area on each side to avoid pressure on the active area causing Mura (uneven brightness).
- FPC Handling: Must strictly follow the "Bending Diagram" in the specification to avoid FPC breakage due to too small a bending radius or repeated bending.
- Heat Dissipation: Backlight LEDs generate heat. Heat dissipation design should be considered for enclosed spaces or high-temperature environments.
4. Electrical & Optical Characteristics
Electrical Characteristics:
- Supply Voltages:
- Logic/Interface Power (VCC/IOVCC): Typically 3.3V or 1.8V.
- Panel Drive Power (AVDD/VCI): Common values are 3.3V, 5.0V, or higher, used to generate grayscale voltages.
- Backlight Power (LEDA): Depends on the number of LEDs in series and type, ranging from 5V to over 30V.
- Power Consumption: Total module power is primarily determined by the backlight. Typical value (excluding backlight) may be below 0.5W. Total power with backlight at full brightness may range from 1W to 3W, depending on brightness and LED efficiency.
- Interface Type: Includes RGB parallel interface, LVDS, MIPI, etc. Older models (e.g., I14) may primarily use RGB, while newer models may support higher-speed LVDS or MIPI.
Optical Characteristics (Typical Values):
- Brightness: Standard model brightness typically ranges from 250-500 cd/m². High-brightness versions (e.g., for outdoor use) can exceed 1000 cd/m².
- Contrast Ratio: Usually > 500:1, with high-quality models reaching 1000:1 or higher.
- Viewing Angle: Varies based on technology used (TN, IPS, FFS, etc.).
- Standard TN: Narrower viewing angle (e.g., Left/Right 70°, Up/Down 50°).
- Wide-Viewing Angle Models (e.g., LS070T06): Can achieve Left/Right 85°, Up/Down 85° levels.
- Color Gamut: Standard a-Si TFT LCD typically covers 50%-70% of NTSC color gamut.
5. Reliability Testing & Quality Standards
LESSON's specifications (e.g., LS070I14, LS070T16) include detailed reliability test items, reflecting stringent product quality requirements. Test items typically include:
