3.3 Timing Characteristics (From Section 8)
3.3.1 LCD Power On Sequence (From Section 8-1)
The module requires a specific power-up sequence to ensure proper initialization. The sequence uses the MIPI DSI interface (4 lane * 2 port, WQHD 1440x2560, VSP=5.9V, VSN=-5.9V, VDDIO=1.8V). Key timing parameters include:
| Action | Timing/Delay | Notes |
|---|---|---|
| Set RESX = L | - | Step 1 |
| Turn on IOVDD (Typ 1.8V) | Wait min 200ms | Wait for IOVDD=90% |
| Turn on AVDD+ (Typ 5.9V) | Wait 20ms | Wait for VSP->VSN ordering |
| Wait for VSN | Wait 20ms | Step 6 |
| RESX = L (again) | Wait min 10ms | Ensure RESX low period |

Note: The full sequence in the specification includes 17 steps. The table above highlights the critical power-up and reset timing. The MIPI I/F must first be in LP mode after IOVDD is stable, then transition to HS mode after the reset sequence.

4. Application Guidelines & Critical Notes
When integrating the LSC064I01-MP-V1 module, engineers must adhere to the specific guidelines outlined in the specification to ensure optimal performance and reliability.
- Power Supply Sequence: The module requires a precise power-up sequence: IOVDD → AVDD+ → AVDD- → RESX release. Failure to follow this sequence may cause latch-up or improper initialization. The power-down sequence must be the reverse of power-up.
- High-Speed MIPI Design: With 8 data lanes plus 2 clock lanes (dual port MIPI), PCB layout must maintain strict 100Ω differential impedance control. The total data rate is very high to support WQHD at 60Hz. Trace length matching within lanes and between ports is critical for signal integrity.
- Backlight Driver: The LED backlight uses two separate channels (LED1 and LED2). Each channel requires a constant current driver with typical 25mA. The total backlight power dissipation is 77.5mW (TYP). Ensure the driver can provide the correct voltage based on the LED Vf (Typ 2.9V at 20mA). PWM dimming is available via the PWM pin.
- Touch Panel Interface: The TP controller is powered via VDDH_3.3V and VDD_3.3V pins. It communicates over I2C (SCL, SDA) with an interrupt (INT/RST). Proper pull-up resistors are needed on the I2C lines. The I2C address is selected via the CTS1 pins.
- Mechanical Mounting: The module is relatively thin (approx. 2.92mm). The FPC connector is a HIROSE BM14B series, 60-pin, 0.4mm pitch. Special care must be taken during connector mating and FPC handling. The module has an Ag shield area on the back; ensure proper grounding and avoid shorting.
- Optical Performance: The module provides excellent optical performance with 90% NTSC and 400 cd/m² brightness. For consistent color reproduction, perform optical calibration using the specified chromaticity coordinates (x=0.300, y=0.320, TYP).
