The part number **JH177128160ACNUWNFFEWC** follows a specific naming convention typically associated with **industrial-grade display modules**, specifically high-resolution TFT LCD panels. Below is a breakdown of the electronic components and specifications derived from this alphanumeric string. --- ### 1. Component Specification Overview This part is a specialized high-density display component. The internal architecture typically consists of a liquid crystal layer, a backlighting unit (BLU), and integrated driver ICs. | Parameter | Details | | :--- | :--- | | **Component Type** | TFT-LCD Module (Thin Film Transistor) | | **Resolution** | 128 x 160 Pixels | | **Interface Type** | Typically SPI or MCU 8-bit/16-bit | | **Driver IC** | Usually ST7735S or ILI series (internal) | | **Backlight** | White LED (WLED) | | **Color Depth** | 65K / 262K Colors | --- ### 2. Breakdown of the Part Number While specific manufacturer codes vary, the segments of this string represent the following electronic characteristics: * **JH**: Manufacturer Identifier (often Jinhui or similar specialized display manufacturers). * **177**: Indicates a **1.77-inch** diagonal screen size. * **128160**: Represents the **resolution** (128 columns by 160 rows). * **ACNU**: Often refers to the Connector Type and Pinout configuration (FPC - Flexible Printed Circuit). * **W/N**: Denotes "White" backlight and "Normal" temperature range or viewing angle. * **FF/EW**: Refers to the physical housing and the "Extended Wide" viewing polarizer or specific glass thickness. --- ### 3. Electronic Architecture Inside the module, the electronic components are organized as follows: 1. **Glass Substrate:** Contains the TFT matrix that acts as a switch for each pixel. 2. **FPC (Flexible Printed Circuit):** The orange ribbon cable containing the data lines (SDA, SCL, CS, RES, DC). 3. **Driver IC (COG):** The "Chip-on-Glass" controller that translates digital signals into analog voltages to twist the liquid crystals. 4. **LED Circuitry:** A series of surface-mount LEDs (usually 2 to 4) connected in parallel or series to provide the backlight. --- ### 4. Sample Connection Pinout (Typical) If you are integrating this into a microcontroller system (like Arduino or ESP32), the pins generally function as follows: ```cpp // Typical SPI Pin Mapping #define TFT_CS 10 // Chip Select #define TFT_RST 9 // Reset #define TFT_DC 8 // Data/Command #define TFT_MOSI 11 // Data Out #define TFT_SCLK 13 // Clock ```
