Based on the string provided (**JH395320480BCNDMNFZCWC**), this appears to be a highly specific manufacturer Part Number (MPN) or a serialized tracking code, likely belonging to the category of **TFT LCD Display Modules** or specific industrial power components. Below is a breakdown of how these alphanumeric characters typically translate into electronic specifications in the context of display technology. --- ### 1. General Component Breakdown While specific proprietary codes vary by manufacturer (such as JHD, JYA, or BOE), the string follows a standard logic for electronic displays: | Segment | Typical Meaning | Description | | :--- | :--- | :--- | | **JH** | Manufacturer Prefix | Often identifies the factory or brand (e.g., JingHao or similar). | | **395** | Physical Size | Likely refers to a **3.95-inch** diagonal screen size. | | **320480** | Resolution | Indicates a resolution of **320 x 480 pixels** (HVGA). | | **BCN** | Backlight/Connector | "B" often stands for LED Backlight; "CN" for specific Connector types. | | **DM** | Driver/Module Type | Defines the internal IC driver (e.g., ILI9488 or ST7796). | | **NFZCWC** | Production/Interface | Custom codes for FPC (Flexible Printed Circuit) layout or wide-temp range. | --- ### 2. Technical Specifications Based on the part number's structure, here are the likely electronic characteristics: * **Display Technology:** TFT LCD (Thin Film Transistor). * **Resolution:** 320 (RGB) x 480 Dots. * **Interface:** Likely **MCU 8/16-bit** or **SPI** (common for this resolution size). * **Active Area:** Approximately 55.44 x 83.52 mm (standard for 3.95"). * **Color Depth:** 65K/262K colors. * **Operating Voltage:** Usually 2.8V to 3.3V for logic. --- ### 3. Key Electronic Sub-assemblies An electronic part like this consists of three primary layers: 1. **The Glass (Cell):** Contains the liquid crystals and color filters. 2. **The Driver IC:** A silicon chip mounted on the glass (COG) that translates data into visual signals. 3. **The Backlight Unit (BLU):** A string of white LEDs connected in series or parallel to provide illumination. --- ### 4. Implementation Example (Pseudo-Code) If you are interfacing this part with a microcontroller (like an ESP32 or Arduino), the initialization code usually looks like this: ```cpp // Example initialization for a 320x480 TFT Driver #include TFT_eSPI tft = TFT_eSPI(); void setup() { tft.init(); tft.setRotation(1); // Set landscape or portrait tft.fillScreen(TFT_BLACK); tft.drawString("JH395 Module Active", 10, 10); } ``` ---
