The part number **JH22240320BCNUNNFZCWC** is a highly specific manufacturer code, typically associated with specialized electronic components like **TFT LCD Display Modules** or custom **Capacitive Touch Panels**. While this exact string is often a proprietary "intelligent part number" used by manufacturers (such as JHD, Orient Display, or similar industrial vendors), we can decode the general structure of such components below. --- ### Component Breakdown Based on standard industry naming conventions for display modules, here is the functional breakdown of what these characters usually represent: | Segment | Typical Meaning | Description | | :--- | :--- | :--- | | **JH** | Manufacturer Prefix | Often refers to the factory brand (e.g., JHD/Jinhui). | | **22240320** | Resolution | Indicates a **240 x 320** pixel resolution (QVGA). | | **BC** | Interface/Controller | Likely stands for **MCU/RGB** interface or a specific controller IC. | | **NU/NN** | Backlight/Type | "N" often denotes **Normal Temperature** or **No Touch**. | | **FZCWC** | Custom Config | Refers to FPC (Flexible Printed Circuit) shape and connector type. | --- ### Technical Specifications If this is a standard 2.4-inch to 3.2-inch TFT module (common for this resolution), the specifications are likely as follows: 1. **Display Technology:** TFT LCD (Thin Film Transistor). 2. **Resolution:** 240 (RGB) x 320 Pixels. 3. **Interface:** 8/16-bit Parallel or 3/4-wire SPI. 4. **Voltage (VCC):** Typically 2.8V to 3.3V. 5. **Backlight:** White LED (Parallel or Series). --- ### Pinout Configuration (Common) *Most displays in this series utilize a 37-pin to 50-pin FPC connector. Below is a simplified representation of the logic:* ```c // Example Pin Logic for MCU Interface 1-10: Data Bus (DB0 - DB15) 11: CS (Chip Select) 12: RS/DC (Register Select) 13: WR (Write Signal) 14: RD (Read Signal) 15: RESET (Hardware Reset) 16: VDD (Power Supply) 17: GND (Ground) ``` --- ### Identification Tips If you are trying to source this part or find a datasheet: * **Check the FPC:** Look for a smaller code printed directly on the orange/yellow flexible ribbon cable. * **Controller IC:** If you can see the glass under a microscope, look for the driver IC (common ones are **ILI9341** or **ST7789V**).
