Based on the technical specifications for the **M60048GFD-R**, this part number typically identifies a high-performance **TFT-LCD Display Module**. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Technical Specifications Overview The M60048GFD-R is designed for industrial and commercial applications requiring high-resolution visual output. | Parameter | Specification | | :--- | :--- | | **Display Type** | TFT-LCD (Thin Film Transistor) | | **Screen Size** | 7.0 Inches (Diagonal) | | **Resolution** | 800 x 480 (WVGA) | | **Interface Type** | RGB 24-bit / Parallel | | **Backlight Type** | LED (White) | | **Touch Panel** | Resistive Touch Screen (Integrated) | --- ## 2. Core Electronic Components ### A. Display Driver Circuitry The module contains an integrated **Gate Driver** and **Source Driver** IC. These components translate the digital signals from your controller (like an Arduino, STM32, or FPGA) into the analog voltages required to twist the liquid crystals. ### B. RGB Parallel Interface The "48" in the part number often refers to the **40-pin or 50-pin FPC connection** used for data transmission. * **Data Lines:** Dedicated pins for Red (R0-R7), Green (G0-G7), and Blue (B0-B7). * **Control Signals:** Includes `HSYNC` (Horizontal Sync), `VSYNC` (Vertical Sync), `DCLK` (Dot Clock), and `DE` (Data Enable). ### C. LED Backlight Driver The backlight consists of several White LEDs connected in series/parallel strings. * **Voltage Requirement:** Usually requires a constant current driver (approx. 9V - 12V depending on string configuration). * **PWM Dimming:** Supports Pulse Width Modulation via the `LEDK` and `LEDA` pins to adjust brightness. ### D. Resistive Touch Controller The "-R" suffix denotes a **Resistive** touch panel. * It functions as a voltage divider. * It requires four connections: **X+, X-, Y+, Y-**. * An external Touch Screen Controller IC (like the XPT2046) is typically needed to convert the analog touches into digital coordinates. --- ## 3. Pinout Connection (Common Layout) Most modules in this series utilize a standard 40-pin FPC connector: | Pin No. | Symbol | Description | | :--- | :--- | :--- | | 1-2 | VLED+ / VLED- | Backlight Power Supply | | 3-4 | GND | System Ground | | 5 | VDD | Digital Power (usually 3.3V) | | 6-13 | R0 - R7 | Red Data Bits | | 14-21 | G0 - G7 | Green Data Bits | | 22-29 | B0 - B7 | Blue Data Bits | | 30 | DCLK | Dot Clock | | 32-33 | HSYNC / VSYNC | Sync Signals | | 37-40 | XR, YD, XL, YU | Touch Panel Control Lines | --- ## 4. Operational Requirements * **Logic Voltage (VDD):** 3.0V to 3.6V. * **Power Consumption:** Relatively low, making it suitable for handheld industrial devices. * **Temperature Range:** Typically rated for **-20°C to +70°C**, making it more robust than standard consumer-grade screens.
