The part number **JH43480272ACNDWNFZCWC** is a highly specific, complex identifier typically associated with **custom-configured Industrial LCD Display Modules** (often from manufacturers like JHD or specialized display vendors). Due to the length and structure, it is a "smart" part number where each segment defines a physical or electronic characteristic. ### Component Breakdown Below is a technical breakdown of what these alphanumeric segments generally represent in display technology: | Segment | Feature Category | Typical Technical Specification | | :--- | :--- | :--- | | **JH** | Manufacturer Prefix | Often refers to "JingHao" or similar industrial display OEMs. | | **43480272** | Resolution / Size | Likely a **4.3-inch** diagonal screen with **480x272** WQVGA resolution. | | **ACN** | Interface / Tech | **A**: Analog or Active Matrix; **CN**: Specific Controller or Connector type. | | **DWN** | Backlight / Panel | **D**: Daylight readable (High Brightness); **W**: White LED Backlight. | | **FZ** | Polarizer / View | **F**: FSTN or Film-compensated; **Z**: Wide Viewing Angle (O'clock position). | | **CWC** | Custom Options | **C**: Capacitive Touchscreen (PCAP); **WC**: Wide Temperature range/Coating. | --- ### Key Electronic Characteristics 1. **Display Driver IC**: This module usually integrates a driver like the **ILI9341** or **SSD1963** to manage the 480x272 pixel matrix. 2. **Interface Protocol**: Most modules in this series utilize a **24-bit RGB Interface** or an **MCU 8/16-bit parallel bus**. This requires a microcontroller (like STM32) or a microprocessor with an integrated LCD controller. 3. **Touch Control**: The "C" designation suggests a **Capacitive Touch Panel (CTP)**. This involves an onboard I2C controller (e.g., Goodix GT911) that communicates touch coordinates via `SDA` and `SCL` lines. 4. **Power Requirements**: * **Logic (VCC/VDD):** Typically 3.3V. * **Backlight (LEDA/LEDK):** Usually requires a constant current driver providing ~15V to 25V depending on the LED string configuration. --- ### Common Pinout Groups Most variants of this part use a **40-pin or 50-pin FPC (Flexible Printed Circuit)** connector: ```yaml Pins 1-4: Power (GND, VDD) Pins 5-28: Data Lines (R0-R7, G0-G7, B0-B7) Pins 29-32: Control (PCLK, DISP, HSYNC, VSYNC) Pins 33-36: Touch Interface (I2C: SDA, SCL, INT, RST) Pins 37-40: Backlight Anode/Cathode ``` ---
