The part number **JH35320480ACNDWNTZCWC** corresponds to a specialized **Liquid Crystal Display (LCD)** module, likely an Industrial or Automotive-grade TFT (Thin Film Transistor) display. Based on standard industry naming conventions for display modules, here is a breakdown of the electronic specifications and characteristics: ### 1. Technical Specifications Table | Feature | Detail | Description | | :--- | :--- | :--- | | **Display Type** | TFT-LCD | Active matrix color display | | **Resolution** | 320 x 480 | Half-VGA (HVGA) resolution | | **Size** | 3.5 Inch | Measured diagonally | | **Interface** | RGB / MCU / SPI | Standard digital signal interface | | **Touch Panel** | Capacitive (CTP) | Indicated by the "CW" suffix (Capacitive Window) | | **Backlight** | White LED | Low power consumption illumination | | **Orientation** | Portrait/Landscape | Configurable via software | --- ### 2. Part Number Breakdown (Functional Logic) While specific to the manufacturer (likely Jinhui or a similar Tier 2 display house), the code typically follows this logic: * **JH**: Manufacturer Prefix (e.g., Jinhui Electronics). * **35**: Screen Size (3.5 inches). * **320480**: Native Resolution (320 x 480 pixels). * **ACN**: Revision or glass type code (Anti-Glare or Clear). * **D**: Driver IC series indicator. * **WNT**: Wide Temperature range (Industrial grade, usually -20°C to +70°C). * **ZCWC**: Specific assembly code, likely indicating a **Capacitive Touch Panel** with a specific bonded cover lens. --- ### 3. Key Electronic Components * **Driver IC:** This module contains an integrated circuit (often an ILI9488 or similar) that converts the digital signals from a microcontroller (MCU) into the analog voltages required to drive the liquid crystals. * **FPC (Flexible Printed Circuit):** A thin, flexible cable extending from the module that carries data, power (VCC/IOVCC), and ground. * **LED Driver Circuit:** The backlight requires a constant current source. Usually, this consists of several white LEDs connected in series or parallel, requiring approximately 18V-20V depending on the configuration. * **Touch Controller:** Since it is a "CWC" (Capacitive) model, it includes a separate I2C-based controller (like a FocalTech or Goodix IC) mounted on the touch ribbon cable. --- ### 4. Common Applications Due to its 3.5" size and HVGA resolution, this part is commonly used in: 1. **Handheld Terminals:** POS systems or inventory scanners. 2. **Smart Home:** Thermostats and security control panels. 3. **Medical:** Portable patient monitoring devices.
