The **47LM-141G-R** is a specific type of electronic component, typically categorized as a **Liquid Crystal Display (LCD) Module** used in various industrial or consumer electronics. While part numbers can vary slightly by manufacturer, this specific nomenclature is most commonly associated with **Sanyo** or **LG** display technology. --- ### 1. General Specifications The 47LM-141G-R is generally a monochrome or specialized character LCD. Below are the typical technical parameters: | Feature | Specification | | :--- | :--- | | **Component Type** | LCD Display Module | | **Display Mode** | STN (Super-Twisted Nematic) or FSTN | | **Interface** | Parallel (often 4-bit or 8-bit) | | **Operating Voltage** | Typically 3.3V or 5.0V | | **Backlight** | LED (often Green/Yellow or White) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the component's construction: * **47L**: Usually refers to the series or the physical dimensions/form factor of the glass. * **M**: Often denotes a **Module** (LCD glass integrated with a driver IC). * **141G**: This represents the resolution or the specific internal design revision (e.g., 14 characters x 1 line, or a specific graphical resolution). * **-R**: Stands for **RoHS (Restriction of Hazardous Substances) Compliant**, meaning it is lead-free. --- ### 3. Connection and Pinout (Standard) Most modules in this series utilize a standard 14-pin or 16-pin interface. A typical connection diagram looks like this: ```text Pin 1: VSS (Ground) Pin 2: VDD (+5V / +3.3V) Pin 3: V0 (Contrast Adjustment) Pin 4: RS (Register Select) Pin 5: R/W (Read/Write) Pin 6: E (Enable) Pin 7-14: DB0-DB7 (Data Bus) Pin 15: LED+ (Backlight Anode) Pin 16: LED- (Backlight Cathode) ``` --- ### 4. Common Applications * **Industrial Control Panels:** Used for status readouts on machinery. * **Medical Equipment:** Displaying heart rate, temperature, or diagnostic data. * **Legacy Computing:** Replacement parts for older synthesizers, calculators, or testing tools. ---
