HR215WU1-120 Electrical Architecture
In hardware development and high-speed PCB layout design, maintaining the signal integrity of the HR215WU1-120 2-ch 8-bit LVDS interface requires following these key electrical guidelines:
1. Signal Architecture & Timing
l Dual-channel transmission: Odd channels (O-CLK, O-D0~D3) and even channels (E-CLK, E-D0~D3) transmit pixel data in parallel for odd/even columns.
l Timing encoding: Using clock-based serialization, four differential pairs (D0~D3) transmit 28-bit data per cycle, including 24-bit RGB color data and DE/HSYNC/VSYNC control signals.
2. 100Ω Differential Impedance
l The LCD receiver integrates an internal 100Ω termination resistor.
l PCB differential traces must maintain 100Ω ±10% impedance to avoid signal reflection, overshoot, crosstalk, screen flicker, or data loss.
3. PCB Layout Guidelines
1) Consistent coupling: Differential pairs must keep constant trace width and spacing without branching.
2) Length matching:
l Pair skew ≤ 5mil
l Channel skew ≤ 50mil
3) Stable return path: Traces should route above a continuous GND plane; add GND vias near signal vias during layer transitions.
4) Noise isolation: Keep LVDS traces away from high-frequency switching signals such as DC-DC inductors and PWM lines, following the 3W spacing rule.
HR215WU1-120 Mechanical & Structural Integration
The HR215WU1-120 has an outline dimension of 495.6 mm × 292.2 mm, with an active area of 476.064 mm × 267.786 mm. The module features a compact structure with a slim thickness of 8.2 mm to 10.7 mm. It is suitable for metal enclosure installation or external PCAP touch integration.
In addition, precision-aligned mounting holes are symmetrically arranged on the sides. The mechanical drawing specifies 4-M3 screw holes with a maximum thread depth of 3.1 mm and a vertical hole pitch of 118 mm. During mechanical design, the screw insertion depth must be strictly controlled within 3.1 mm to avoid damage or pressure on the internal LCD and backlight structure.

What to Consider When Operating?
1) Only handle the pouch when removing the module from the shipping package.
2) Use ESD-safe handling to avoid LCD damage; peel protective film slowly.
3) Avoid shock or pressure due to fragile glass structure.
4) Clean polarizer only with a soft dry cloth; no chemicals.
5) Do not connect/disconnect interface while powered.
6) Place the module display-side down on a flat surface.
7) Handle all connectors and cables gently.
8) Do not lose CLK or ENAB signals during operation to prevent panel damage.
9) Follow correct power sequence strictly to avoid malfunction.
10) Avoid condensation or dew conditions.
11) Do not store or operate in high temperature or high humidity; use anti-static packaging and cool environment.
12) Avoid displaying fixed patterns during aging tests.
13) Long-term static images may cause image sticking.
