# Industrial Specification: Display Driver Circuit

## 1. Technical Definition
An electronic circuit that controls the operation of a display device by converting input signals into appropriate voltage/current levels for pixel activation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.3-5.0 VDC input voltage, 0-100 mA output current per channel, -40°C to +85°C ambient temperature**. Failure boundary: **Input voltage exceeding 5.5 VDC causes MOSFET gate oxide breakdown at 10 MV/cm electric field strength, output current exceeding 120 mA induces thermal runaway at 150°C junction temperature**, Mechanism: **Electromigration in aluminum interconnects at current densities above 1×10⁶ A/cm² (Black's equation), dielectric breakdown in gate oxide layers at electric fields exceeding 10 MV/cm (Poole-Frenkel conduction)**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
