The part number **JH24240320ACNUNNTHCWC** refers to a high-resolution **TFT Liquid Crystal Display (LCD)** module. Based on the naming convention, this is typically a 2.4-inch display module used in embedded systems and handheld devices. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Display Type** | TFT LCD (Thin-Film Transistor) | | **Screen Size** | 2.4 Inch (Diagonal) | | **Resolution** | 240 x 320 Pixels (QVGA) | | **Interface** | Typically MCU 8/16-bit or SPI (Serial Peripheral Interface) | | **Display Mode** | Transmissive / Normally Black (IPS) or White | | **Touch Panel** | Capactive Touch (CTP) or None (depending on "CW" suffix) | | **Backlight** | White LED (High Brightness) | --- ### 2. Breakdown of the Part Number While specific manufacturers (like JHD or JingHao) have proprietary codes, the string follows a standard industrial logic: * **JH**: Manufacturer Prefix (e.g., JingHao). * **24**: Screen Size (2.4 inches). * **240320**: Resolution (240 RGB x 320 pixels). * **AC**: Version or Revision code. * **NUNN**: Internal configuration (often refers to No polarizer/standard polarizers or specific FPC lengths). * **TH**: Temperature Range (High temperature or Industrial grade). * **CWC**: Often indicates the inclusion of a **Capacitive Touch Panel** (C) and specific **Connector/Wiring** (WC) configurations. --- ### 3. Key Electronic Components Inside this module, the following electronic subsystems are present: 1. **Driver IC (e.g., ST7789V or ILI9341):** The "brain" of the LCD. It receives data from your microcontroller and converts it into voltages to drive the liquid crystal cells. 2. **Flexible Printed Circuit (FPC):** The orange/brown ribbon cable that carries signals (Data, Clock, Reset, Power) between the display and the main PCB. 3. **Backlight Unit (BLU):** A string of 3 to 6 white LEDs connected in series or parallel, requiring a constant current driver (approx. 20mA). 4. **Glass Sandwich:** Two layers of glass containing the Liquid Crystal material and a Color Filter (RGB). --- ### 4. Integration Example (Pseudo-Code) To initialize this display in an embedded environment (like Arduino or STM32), you would typically use an SPI initialization: ```cpp // Example initialization for a 240x320 TFT Driver void setup_display() { LCD_Reset(); // Pulse the Reset pin Write_Command(0x11); // Sleep Out Delay(120); // Wait for driver to wake up Write_Command(0x3A); // Interface Pixel Format Write_Data(0x55); // 16-bit color (RGB565) Write_Command(0x29); // Display ON } ``` ---
