The part number **JH395320480ACNSNNFZCWC** corresponds to a specialized **TFT Liquid Crystal Display (LCD) Module**. This specific nomenclature is often used by industrial display manufacturers (such as JHD or similar vendors) to define the physical and electrical characteristics of the screen. --- ### 🟢 Technical Breakdown of the Component Based on standard industrial display coding conventions, here is a breakdown of what these electronic specifications typically represent: | Specification Segment | Typical Meaning | Description | | :--- | :--- | :--- | | **JH** | Manufacturer Code | Identifies the brand/manufacturer (e.g., JHD). | | **395** | Diagonal Size | Represents a **3.95-inch** display area. | | **320480** | Resolution | Indicates a pixel resolution of **320 x 480** (HVGA). | | **ACN** | Interface Type | Usually refers to an **MCU or RGB interface** with specific pin mapping. | | **SN/NN** | Backlight & Temp | Standard brightness with Normal operating temperature ranges. | | **FZ/CWC** | Controller/Internal Code | Refers to the internal driver IC (often ILI9488 or ST7796S) and revision. | --- ### 🛠️ Key Electronic Features 1. **Display Technology**: It is an **IPS** (In-Plane Switching) or **TFT** (Thin Film Transistor) active matrix display, allowing for full-color rendering. 2. **Driver IC**: These modules typically integrate a specialized controller chip (like the **ST7796S**) that handles the high-speed switching of individual pixels. 3. **Backlight System**: It utilizes a series of White LEDs (WLEDs) connected in parallel or series, requiring a constant current driver (typically 15-20mA per LED). 4. **Signal Interface**: * Uses a multi-pin FPC (Flexible Printed Circuit) connector. * Supports **SPI** (Serial Peripheral Interface), **8/16-bit Parallel**, or **RGB** data transmission. --- ### 📐 Physical & Electrical Specifications | Parameter | Value (Standard) | | :--- | :--- | | **Voltage (VDD)** | 2.8V to 3.3V | | **Interface** | 40-pin or 50-pin FPC | | **Color Depth** | 65K / 262K colors | | **Viewing Angle** | Wide (Full viewing angle if IPS) | | **Touch Panel** | Capable of supporting Capacitive (CTP) or Resistive (RTP) overlays. | --- ### ⚠️ Integration Notes for Engineers * **Initialization**: This part requires a specific "Init Code" sent via software to the internal registers to define brightness, orientation, and gamma curves. * **Power Sequencing**: Ensure VDD reaches stability before sending reset signals to prevent latch-up or permanent damage to the driver IC.
