The **FPM3254H-R010DFP** is a high-performance, industrial-grade TFT Liquid Crystal Display (LCD) module. It is commonly used in ruggedized equipment, medical devices, and professional monitors where high resolution and reliability are paramount. --- ### ## Technical Specifications Below are the primary electronic and optical characteristics of the module: | Feature | Specification | | :--- | :--- | | **Panel Type** | a-Si TFT-LCD | | **Diagonal Size** | 32.0 inches | | **Native Resolution** | 3840 × 2160 (UHD / 4K) | | **Aspect Ratio** | 16:9 | | **Interface Type** | V-by-One HS (8 lanes) | | **Input Voltage** | 12.0V (Typical) | | **Luminance** | ~350 - 450 cd/m² | | **Backlight Type** | WLED (White Light Emitting Diode) | --- ### ## Core Electronic Components #### 1. Interface: V-by-One HS Unlike standard consumer monitors that use LVDS, this module utilizes **V-by-One HS**. - **Efficiency:** It reduces the number of wires required to transmit 4K data. - **Clock Recovery:** It uses an embedded clock to minimize Electro-Magnetic Interference (EMI) and solve skew issues between data lines. #### 2. The T-CON (Timing Controller) Board The T-CON acts as the "brain" of the panel. It: - Receives the digital image data from the V-by-One interface. - Converts the data into signals that drive the **Source Drivers** and **Gate Drivers** on the glass. - Manages the refresh rate and pixel charging timing to ensure a crisp 4K image. #### 3. Backlight Driver (Inverter/LED Driver) Since this is a non-emissive display, it requires a WLED backlight string. - The electronics include a DC-to-DC boost converter to supply the necessary voltage to the LED strings. - It supports **PWM (Pulse Width Modulation)** for brightness dimming. #### 4. Power Management Circuitry The module requires a stable 12V supply. Internal regulators (LDOs and Buck converters) step this down to: - **1.8V / 3.3V:** For logic and T-CON operation. - **AVDD (~15V):** High voltage for the analog column drivers. - **VGH/VGL:** High/Low voltages used to switch the TFT transistors on the glass substrate. --- ### ## Connection Diagram Concept The typical electronic layout for integrating this part is as follows: ```mermaid graph LR A[Main Controller/PC] -- V-by-One HS --> B[T-CON Board] B -- Flex Cables --> C[Source/Gate Drivers] C --> D[TFT Glass Panel] E[12V Power Supply] --> B E --> F[LED Driver/Backlight] F --> G[WLED Array] ``` ---
