# Industrial Specification: Display Panel

## 1. Technical Definition
A visual interface component that presents information, data, and system status to operators within a Human-Machine Interface (HMI) system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-70°C ambient temperature, 20-80% relative humidity, 100-240V AC ±10%**. Failure boundary: **85°C junction temperature for LCD backlight LEDs, 90% relative humidity causing condensation, 264V AC sustained for &gt;100ms**, Mechanism: **Arrhenius equation degradation of organic LED materials (Ea=0.35eV), electrolytic corrosion at dew point, dielectric breakdown in power supply capacitors (BDV=400V/mm)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Backlight LED current exceeding 20mA continuous (If_max rating) | 8 | Luminance decay to &lt;100 cd/m² within 5000 hours (70% initial brightness) | Constant current driver with 18mA limit and thermal foldback at 80°C |
| ESD event &gt;8kV (Human Body Model) on touch interface | 8 | Capacitive sensor IC latch-up (I_latch=200mA), permanent calibration loss | TVS diodes (Vbr=5.5V) on all I/O lines with &lt;1ns response time |
