The part number **JH70800480ACNDWNTHCWC** refers to a high-resolution, industrial-grade Liquid Crystal Display (LCD) module, typically used in embedded systems and human-machine interfaces (HMI). Based on standard industry nomenclature for these types of displays, here is the breakdown of its electronic specifications and features. --- ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Resolution** | 800 x 480 pixels | WVGA Widescreen format | | **Display Type** | TFT-LCD | Thin Film Transistor (Active Matrix) | | **Interface** | RGB 24-bit | Standard parallel interface for video data | | **Backlight** | LED | White Light Emitting Diodes | | **Touch Panel** | Capacitive (CTP) | Multi-touch support (indicated by "CW" suffix) | | **Brightness** | High Luminance | Often rated between 300 to 500 cd/m² | --- ### 2. Key Component Analysis #### A. The TFT LCD Controller The display uses a driver IC (Integrated Circuit) bonded to the glass (COG). This chip converts the incoming RGB signals into voltages that orient the liquid crystals. It manages the timing for vertical and horizontal synchronization (VSYNC/HSYNC). #### B. Capacitive Touch Panel (CTP) The **"CWC"** or **"THC"** segments in the part number usually signify a Capacitive Touch Screen. - **Controller:** Usually uses an I2C interface (e.g., FocalTech or Goodix ICs). - **Durability:** Features a cover glass that protects the display and allows for multi-touch gestures. #### C. Backlight Driver Circuit This part requires a constant current source to drive the series-parallel LED string. - **Voltage:** Typically requires ~9V to 25V depending on the string configuration. - **Dimming:** Supports PWM (Pulse Width Modulation) for brightness control. --- ### 3. Pinout and Connectivity The physical connection is typically an **FPC (Flexible Printed Circuit)** cable. | Section | Pins | Signal Type | | :--- | :--- | :--- | | **Power** | VDD, VCI | 3.3V Logic Power | | **Data** | R0-R7, G0-G7, B0-B7 | 24-bit Color Data | | **Control** | PCLK, DE, HSYNC, VSYNC | Timing Signals | | **Touch** | SDA, SCL, INT, RST | I2C Communication | | **LED** | LED+, LED- | Backlight Power | --- ### 4. Application Areas * **Industrial HMI:** Control panels for factory machinery. * **Automotive:** Secondary dashboard displays or infotainment systems. * **Medical:** Handheld diagnostic device screens. * **Smart Home:** Wall-mounted thermostat or security controllers.
