The part number **JH177128160ACNFNNFZCWC** corresponds to a specialized, high-performance **TFT-LCD Display Module**, typically manufactured by industrial display providers like **Innolux** or localized display solution integrators. This part is commonly used in industrial automation, medical devices, or automotive interfaces. Below is a breakdown of the electronic specifications and characteristics based on the standard naming conventions for this series. --- ### 1. Technical Specifications | Feature | Description | | :--- | :--- | | **Display Type** | Thin Film Transistor (TFT) Active Matrix LCD | | **Resolution** | 128 x 160 Pixels (Commonly 1.8" to 2.4" form factor) | | **Interface** | SPI (Serial Peripheral Interface) or 8/16-bit Parallel | | **Backlight** | White LED (Typically 1-4 LEDs in parallel/series) | | **Driver IC** | Usually ST7735 or ILI9163 equivalent | | **Color Depth** | 65K / 262K Colors (16-bit / 18-bit) | --- ### 2. PIN Configuration (General Layout) Most modules in this series utilize a **Flat Flexible Cable (FFC)** or **Flexible Printed Circuit (FPC)** connector. | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **GND** | Ground | | 2 | **VCC** | Power Supply (Typically 2.8V - 3.3V) | | 3 | **CS** | Chip Select (Active Low) | | 4 | **RESET** | Global Reset Signal | | 5 | **RS/DC** | Register Select / Data Control | | 6 | **SDA** | Serial Data Input | | 7 | **SCK** | Serial Clock | | 8 | **LED+** | Backlight Anode (+) | | 9 | **LED-** | Backlight Cathode (-) | --- ### 3. Key Electronic Characteristics * **Logic Voltage (IOVCC):** Most units operate on a **1.8V to 3.3V** logic level. Connecting a 5V microcontroller (like an Arduino Uno) directly to the data lines without a level shifter can damage the internal Driver IC. * **Power Consumption:** Extremely low, typically drawing **under 50mA** even with the backlight at full brightness. * **Response Time:** Optimized for static UI elements; however, it supports up to 30-60 frames per second (FPS) depending on the interface clock speed. ### 4. Code Implementation (Example) To drive this part using a standard SPI library (like Adafruit_ST7735 in C++), the initialization would look like this: ```cpp #include // Core graphics library #include // Hardware-specific library for ST7735 #define TFT_CS 10 #define TFT_RST 9 #define TFT_DC 8 // Initialize ST7735 display (128x160 resolution) Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST); void setup() { tft.initR(INITR_BLACKTAB); // Initialize display chip tft.fillScreen(ST7735_BLACK); // Clear screen } ``` ---
