The **W2TS-213-R2** is a specific industrial-grade touch screen monitor component, typically categorized under the **WTS Series** of open-frame or panel-mount monitors. These units are commonly used in kiosks, industrial automation, and point-of-sale (POS) systems. --- ### 1. Key Technical Specifications Below are the primary electronic and physical specifications for the W2TS-213-R2: | Feature | Specification | | :--- | :--- | | **Display Size** | 21.5-inch Diagonal | | **Native Resolution** | 1920 x 1080 (Full HD) | | **Aspect Ratio** | 16:9 | | **Touch Technology** | Projective Capacitive (PCAP) - Multi-touch | | **Brightness** | Approximately 250 - 300 cd/m² | | **Interface/Inputs** | VGA, HDMI, DisplayPort (DP) | | **Touch Interface** | USB (Plug-and-Play) | | **Power Input** | 12V DC (usually via an AC/DC adapter) | --- ### 2. Electronic Component Breakdown The device consists of several critical electronic sub-assemblies: #### A. The LCD Controller Board (AD Board) This is the "brain" of the monitor. It converts incoming video signals (HDMI/VGA) into the LVDS or eDP signals required by the LCD panel. - **Scaling:** It handles resolution scaling to ensure the image fits the 1080p screen. - **OSD (On-Screen Display):** Controls brightness, contrast, and color balance. #### B. The Touch Sensor & Controller The "213" in the model name refers to the 21.5-inch size, while the "TS" denotes Touch Screen. - **Sensor:** A glass overlay with a conductive grid. - **IC Controller:** Usually mounted on a flexible printed circuit (FPC), this chip translates touch coordinates into USB data for the host computer. #### C. Backlight Inverter/Driver Modern units like the R2 version use **LED backlighting**. The driver circuit regulates the constant current required to power the LEDs behind the liquid crystal layer, ensuring flicker-free operation and dimming capabilities. #### D. Connectivity Ports The "R2" revision often indicates a specific layout of the I/O (Input/Output) shield: - **Video:** Standard 15-pin D-sub (VGA) and digital HDMI. - **Power:** A barrel-jack connector for DC 12V input. - **Data:** USB Type-B or Type-A for the touch interface. --- ### 3. Applications and Environment The "W2TS" series is electronically shielded to operate in environments with electromagnetic interference (EMI). * **Industrial Control:** High resistance to dust and moisture (often IP65 rated on the front bezel). * **Self-Service:** Designed for 24/7 continuous operation. * **Mounting:** Supports VESA 75/100 standards for integration into larger machines.
