4. Application Guidelines & Critical Notes

When integrating the LSC116I02-E-V1 module, engineers must adhere to the specific guidelines outlined in the specification to ensure optimal performance and reliability.

  • Power Supply (VDD & VBL): The module requires two power supply rails: VDD (3.3V) for the LCD logic and VBL (12V Typ) for the LED backlight. The backlight requires an external constant current driver (235mA Typ). Correct power sequencing is crucial: Backlight must be turned on after the logic and interface signals are valid.
  • eDP Interface: The module uses eDP 1.2 with 2 lanes. The host must support eDP at 2.7Gbps per lane. The hot plug detect (HPD) signal must be monitored for connection status.
  • Backlight Control: The backlight is controlled via BL_ENABLE (On/Off) and BL_PWM DIM (PWM for brightness). The PWM frequency range is 200 Hz to 2000 Hz with a duty ratio from 1% to 100%.
  • Mechanical Integration: The module integrates a cover glass (LENS) and capacitive touch panel (CTP). The outline drawing provides critical dimensions for mechanical design. The active area is 256.32(H) × 144.18(V) mm. The lens has a 3H hardness anti-glare coating.
  • Connector: The module uses an I-PEX 20455-030E-76 connector. The corresponding connector is the 20453-030T (I-PEX). The manufacturer notes that they are not responsible for product quality if a non-recommended connector is used.
  • Touch Panel: The integrated CTP uses a USB interface and a GT2931 controller. The touch panel has its own dedicated connector and power supply.
  • Handling Precautions: The panel is made of glass and can break if dropped. CMOS LSI is used, so static electricity precautions must be taken. The polarizer is anti-glare; care must be taken when attaching protective boards to avoid optical interference fringes.
  • RoHS Compliance: This module is compliant with the RoHS Directive.

5. Conclusion & Design-In Support

The LSC116I02-E-V1 from Lesson Smart Display Technology is a feature-rich 11.6-inch FHD Open-Cell display. Its advanced Oxide TFT technology, eDP 1.2 interface, integrated touch panel, and wide viewing angles make it an excellent choice for high-performance multimedia applications such as notebooks, all-in-one PCs, and portable devices.

For design-in support, it is strongly recommended to:

  • Obtain and review the full Product Specification (Revision 1.0) for complete timing diagrams, the mechanical outline drawing, and the CTP specification.
  • Design the power supply to provide a clean 3.3V rail (VDD) and a constant current backlight driver (12V, 235mA). Note the backlight power-on timing and voltage drop conditions.
  • Use the specific I-PEX connector (20453-030T) for the main FPC.
  • Contact the manufacturer for evaluation kits, sample requests, and technical support during the design-in phase.

This module is engineered to deliver consistent, bright, and reliable display performance for the latest generation of portable and multi-media devices.
