The specification describes the eDP interface power up/down sequence for normal system operation, with timings defined for LCD_VCC, Black Video, HPD from Sink, Sink Aux Channel Operation, Main-Link, and Display/Backlight enable. The interface timings should match the 1920x1200 / 60Hz manufacturing guide line timing.

The specification defines the measurement method for electro-optical characteristics, including luminance uniformity (5 or 13 points), average luminance of white (Y_L), contrast ratio, and cross talk (CT). The viewing direction is defined as Normal Line θ=0°, with the standard measurement setup using a photo detector positioned 50cm from the center of the LCD panel with a field of 2°.
4. Application Guidelines & Critical Notes
Intended Use
- 10.1-inch display applications requiring WUXGA (1920×1200) resolution and eDP interface.
- Systems that require high bandwidth and modern display interface standards.
- Embedded systems, portable devices, and monitors using a 16:10 aspect ratio display.
Critical Design Considerations
- eDP Interface Compliance (VESA V1.3): The module requires an eDP source that complies with VESA DisplayPort Standard V1.3. The host must correctly manage the link training, AUX channel communication, and HPD signal.
- Power Supply (VDD = 3.3V): The module requires a stable 3.3V power supply (VDD) on the LCD_VCC pins (13-16). The inrush current can reach up to 2000mA, so the power supply should be capable of handling this. The ripple voltage should not exceed 100mV p-p.
- External Backlight Driver with Analog Brightness Control: The module provides direct access to the LED power supply (BL_PVR) and control signals (LED_EN, PWM). The backlight requires:
- An external power supply (VLED) ranging from 5V to 20V.
- An enable signal (LED_EN) within 2.5V to 5.5V for high, and below 0.8V for low.
- A PWM signal for brightness control with a frequency between 200Hz and 20kHz, and a duty cycle from 5% to 100%.
- Power-On Sequence: The module has a specific power-on timing sequence that must be followed. The specification provides a diagram showing the relationship between LCD_VCC, eDP signals (Black Video, HPD), Aux Channel operation, Main-Link, and Display/Backlight enable. Failing to follow this sequence can cause damage or operational issues.
- Display Timing (1920x1200 @ 60Hz): The interface timings should match the 1920x1200/60Hz manufacturing guide line timing. Ensure the host's eDP transmitter is configured for this resolution and refresh rate.
- Backlight LED Life-Time (15,000 Hours): The LED backlight is rated for a minimum of 15,000 hours of operation (to 50% degradation of initial luminance at IF=20.5 mA, Ta=25°C). This is a key factor in the product's lifespan.
- Mechanical Integration: The outline dimension drawing shows the panel outline is 228.60 ± 0.50 mm (active area 216.81 ± 0.30 mm) and 148.17 ± 0.50 mm (active area 135.50 ± 0.30 mm), with a maximum thickness of 4.85mm. Careful mechanical design is required to accommodate the FPC and connector.
Handling & Compliance
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass – handle with care.
- Do not attempt to disassemble or modify the LCD module.
- All NC (No Connection) pins should be left open.
