3.2 Electrical & Interface Specifications

3.2.1 TFT LCD Open Cell DC Characteristics

Notes:

• Note 1: Supply voltage is 12.0V, Frame rate is 60Hz, Clock frequency = 75.4MHz.
• Note 2: The duration of rush current is about 2ms and rising time of Power Input is 1ms (min).
• LVDS Interface: LVDS Swing Voltage (VID) is ±100 to ±300 mV. Common Input Voltage (VLC) is 1.0 to 1.4V.
• CMOS Interface: Input High Threshold Voltage (VIH) is 2.7 to 3.3V. Input Low Threshold Voltage (VIL) is 0 to 0.6V.

3.2.2 Backlight Unit (LED Light Bar)

3.2.3 LVDS Timing Characteristics (Partial Pin Assignment)

Notes on Power Sequencing:

1. Back Light must be turned on after power for logic and interface signals are valid.

3.3 Optical & Electro-Optical Characteristics

4. Application Guidelines & Critical Notes

• Intended Use: Large format displays for commercial signage, public information displays, high-end monitors, medical imaging.
• Critical Design Considerations:
  1. Power Supply: Requires a robust 12Vdc (10.8-14Vdc) power supply capable of delivering over 4A for the logic and interface.
  2. Backlight Driver: The module requires an external constant-current LED driver capable of supplying 1300mA (Typ.) at 39V (Typ.) . This is a critical external component.
  3. LVDS Interface: The host system must have an LVDS transmitter that is compatible with the 2-channel LVDS interface definition.
  4. Power Sequencing: Strictly follow the power-on sequence: Logic/Interface → Backlight.
  5. Thermal Management: The total power consumption is up to 74.8W (Cell + BL). A robust thermal management solution is required to dissipate the generated heat.
  6. Rush Current: The peak rush current can be up to 3.3A on power-up. The power supply must be designed to handle this transient.
• Mechanical: The document mentions a mechanical outline dimension but the exact figures are not provided in the text fragment. The full spec must be consulted.

5. Conclusion & Design-In Support

The LS32I01-L-V1 specification outlines a high-performance 32-inch FHD open cell module designed for demanding professional applications. Its standout features are its industry-leading 1000 cd/m² brightness, exceptional 89-degree viewing angles, and high contrast ratio. This is not a simple drop-in module; successful implementation requires a sophisticated external LED backlight driver and a 12V power supply with robust filtering. Engineers should treat this as a core display component that needs significant supporting circuitry for power and control.
