Based on the part number **JH395320480DCNFNNFZCWC**, this appears to be a highly specific SKU typically associated with **LCD Display Modules**, often manufactured by industrial display providers like **Jinghua (JH)** or similar specialized electronic component vendors. Below is a breakdown of the technical characteristics and categories associated with this electronic part. --- ### 1. Component Overview The part is an integrated display assembly commonly used in industrial automation, medical devices, or high-end consumer electronics. | Feature | Specification Details | | :--- | :--- | | **Component Type** | TFT LCD Display Module | | **Resolution** | Likely 320 x 480 pixels (HVGA) | | **Interface** | Typically MCU, SPI, or RGB interface | | **Backlight** | LED (White) | | **Touch Panel** | Depends on suffix; often includes Capacitive (PCAP) or Resistive options | --- ### 2. Part Number Breakdown (Typical) While proprietary, the nomenclature usually follows this logic: * **JH**: Manufacturer prefix (e.g., Jinghua Displays). * **395**: Likely refers to the diagonal size (**3.95 inches**). * **320480**: Represents the pixel resolution (**320 x 480**). * **DCN / FNN**: Internal codes for specific glass types, polarizer types (Transmissive/Reflective), and viewing angles (e.g., IPS for wide viewing). * **FZCWC**: Specific revision or connector configuration (FPC pinout/ZIF connector). --- ### 3. Key Electronic Characteristics These modules require specific driving conditions to function within an electronic circuit: 1. **Driver IC**: Usually integrated onto the glass (COG - Chip on Glass), such as the **ILI9488** or **ST7796S**. 2. **Voltage Supply (VDD)**: Typically operates at **2.8V to 3.3V** for logic. 3. **Backlight Circuit**: Requires a constant current driver (approx. 20mA per LED string) at a higher forward voltage (around 9V-12V depending on serial/parallel LED arrangement). 4. **FPC Connector**: A Flexible Printed Circuit (FPC) usually with 34 to 50 pins to carry data signals and power. --- ### 4. Implementation Requirements To use this part in an electronic design, the following are required: * **Microcontroller/Processor**: Capable of handling the data throughput for 320x480 resolution. * **Level Shifters**: If using a 5V logic system (like Arduino Uno), voltage translation to 3.3V is mandatory to prevent damage. * **Initialization Code**: A specific "Init Shield" or register sequence is required to wake the display and set the gamma curves. ---
