Based on the alphanumeric structure of the part number **JH395320480CCNLMNTHCWC**, this follows the typical naming convention for **TFT LCD Display Modules**. These strings are complex because they embed specific hardware specifications (resolution, interface, backlight, and glass type) directly into the code. --- ### 1. Breakdown of Specifications While specific manufacturer datasheets (such as those from *Jinghua* or *Jing Huarui*) vary, the segment analysis for this part typically breaks down as follows: | Segment | Possible Meaning | Technical Description | | :--- | :--- | :--- | | **JH** | Manufacturer Prefix | Often refers to **Jinghua** or a similar display specialty house. | | **395** | Physical Size | Likely a **3.95-inch** diagonal screen size. | | **320480** | Resolution | **320 x 480 pixels** (HVGA). Common for handheld devices. | | **CC** | Interface Type | Likely **MCU/Parallel** or **RGB** interface pins. | | **NL / MN** | Driver/Glass Type | Indicates the specific Driver IC (e.g., ILI9488 or ST7796) and TN/IPS glass. | | **THCWC** | Customization | Refers to Brightness (Nits), Touch Panel type (Capacitive), and FPC (Cable) version. | --- ### 2. Key Electronic Characteristics A display with these specifications usually operates within the following electronic parameters: #### A. Power Requirements * **Logic Voltage (VDD/VCI):** Typically **2.8V to 3.3V**. * **I/O Voltage (IOVCC):** Often **1.8V to 3.3V** to match the microcontroller logic levels. * **Backlight (LEDA/K):** Usually requires a constant current driver. For a 3.95" screen, this often involves 6-10 LEDs in parallel or series-parallel, requiring **~15-20mA per string**. #### B. Display Technology * **Type:** TFT LCD (Thin Film Transistor). * **Color Depth:** 16.7M colors or 65K colors (depending on the controller setting). * **Viewing Angle:** Given the "CWC" suffix, this is likely an **IPS (In-Plane Switching)** panel, providing wide viewing angles (up to 80/80/80/80). #### C. Integrated Circuits (IC) This part number typically integrates a **Display Controller** and a **Gate Driver** into a single Chip-on-Glass (COG) package. * Common ICs for 320x480 resolution: **ILI9488**, **ST7796S**, or **HX8357**. --- ### 3. Connection and Interfacing The "CCN" portion suggests the flexible printed circuit (FPC) configuration: 1. **Parallel Interface (8/16-bit):** High-speed data transfer suitable for simple MCUs like Arduino Mega or STM32. 2. **SPI Interface:** Sometimes available as a 3-wire or 4-wire option to save pins, though slower for full-screen refreshes. --- ### 4. Summary Table of Hardware Features | Feature | Specification | | :--- | :--- | | **Display Mode** | Transmissive / Normally Black (IPS) | | **Active Area** | Approx. 55.44 x 83.16 mm | | **Touch Interface** | Capacitive (if 'C' denotes Capacitive) via I2C | | **Brightness** | Usually 300 - 500 cd/m² | | **Operating Temp** | -20°C to +70°C |
