The **CCT-49K76D-R** is a specific model of an LCD/LED display panel, commonly utilized in digital signage, industrial monitors, or video wall installations. This part number typically refers to a **49-inch professional-grade display module**. Below is a breakdown of the electronic components and technical specifications associated with this part. --- ### 1. Core Technical Specifications The electronics of the CCT-49K76D-R are designed for high-enduerance and specific optical performance. | Parameter | Specification Details | | :--- | :--- | | **Panel Size** | 49-inch Diagonal | | **Resolution** | Full HD (1920 x 1080) or 4K (Model variant dependent) | | **Backlight Type** | LED (Light Emitting Diode) | | **Bezel Width** | Often "Ultra-Narrow Bezel" (UNB) for video walls | | **Interface** | LVDS (Low-Voltage Differential Signaling) or V-by-One | | **Orientation** | Supports both Landscape and Portrait modes | ### 2. Key Electronic Assemblies The assembly consists of several integrated circuit (IC) layers and boards: #### A. The T-CON Board (Timing Controller) The T-CON is the "brain" of the panel. It translates the video signal from the main logic board into the specific row and column signals required by the LCD pixels. * **Function:** Controls timing of the Source and Gate drivers. * **Components:** Logic ICs, EEPROM (for EDID data), and Gamma correction chips. #### B. LED Backlight Driver (Inverter) Since this is an "R" suffix model (often denoting a specific Revision or Rohs compliance), the backlight driver is highly efficient. * **Voltage:** Typically operates on a 24V DC input. * **PWM Dimming:** Supports Pulse Width Modulation for brightness control. #### C. Source and Gate Driver ICs These are micro-chips bonded directly to the glass (COF - Chip on Film). * **Source Drivers:** Handle the grayscale/color data for each column. * **Gate Drivers:** Switch the rows on and off in sequence. --- ### 3. Connection Interface To drive the CCT-49K76D-R, the following electronic interfaces are standard: 1. **Power Input:** Standard 8-pin or 12-pin headers for 12V/24V power. 2. **Signal Input:** 51-pin or 41-pin LVDS connector. 3. **Backlight Control:** A separate 6-pin to 14-pin connector for "BLON" (Backlight On), "E-PWM" (Dimming), and Ground. ### 4. Common Application Electronics When integrated into a final product, this panel is usually paired with: * **AD Board (Analog-to-Digital):** Converts HDMI/DisplayPort signals to LVDS. * **OSD Keypad:** For manual menu navigation. * **Power Supply Unit (PSU):** Often an industrial-grade AC-DC converter. ---
