Based on the part number **JH35320480BCNRMNFZCWC**, this component is a specific **TFT-LCD (Thin Film Transistor Liquid Crystal Display)** module. While part numbers can vary by manufacturer (often associated with Chinese display module vendors like JHD or similar), the alphanumeric code follows a standard industry convention. --- ### Part Number Breakdown The sequence typically describes the physical and technical specifications of the display: | Code Segment | Specification | Description | | :--- | :--- | :--- | | **JH** | Manufacturer Prefix | Often refers to JingHao or specific OEM display brands. | | **35** | Diagonal Size | **3.5 inches** measured diagonally. | | **320480** | Resolution | **320 x 480 pixels** (HVGA resolution). | | **BCN** | Interface/Controller | Usually indicates a specific controller type (e.g., ILI9488 or ST7796). | | **RM** | Module Type | Reflective/Transmissive or specific backlight mounting. | | **NF** | Touch Panel | Often stands for **Non-Touch** or No Film (standard glass). | | **ZCWC** | Internal Revision | Specific to factory binning, cable orientation, or LED backlight current. | --- ### Technical Specifications Typically, a module with this designation carries the following electronic characteristics: #### 1. Display Hardware * **Technology:** TFT Active Matrix. * **Colors:** 65K / 262K (16-bit or 18-bit depth). * **Viewing Angle:** Standard TN (Twisted Nematic) or IPS depending on the specific "BCN" revision. * **Backlight:** White LED (Parallel or Series arrangement). #### 2. Interface Options Most 320x480 modules of this class support: * **8/16-bit Parallel Interface:** (8080/6800 series MCU interface). * **SPI (Serial Peripheral Interface):** Often 3-wire or 4-wire SPI. * **RGB Interface:** Sometimes available for high-speed video data. #### 3. Power Requirements * **Logic Voltage (VDD/VCI):** 2.5V to 3.3V. * **IO Voltage (VDDIO):** 1.65V to 3.3V. * **Backlight Voltage (Vf):** ~3.2V (per LED) or ~9.6V if 3 LEDs are in series. --- ### Pinout and Connection Most of these displays use a **40-pin or 50-pin FPC (Flexible Printed Circuit)** connector. Common signals include: * `CS`: Chip Select. * `RS / DC`: Register Select / Data Control. * `WR / RD`: Write and Read strobes. * `RESET`: Hardware reset. * `DB0 - DB15`: Data bus lines. --- ### Typical Usage These modules are commonly found in: * Handheld medical devices. * Industrial control panels. * Smart home thermostats. * Arduino/Raspberry Pi DIY expansion shields.
