M240HTN01.2 Structure and Principle
The internal structure of the M240HTN01.2 display panel reflects the precision of TFT-LCD technology. The following explains its working principle from micro-level pixel control to macro-level signal transmission:
1. TFT-LCD Basic Principle
TFT-LCD (Thin-Film Transistor Liquid Crystal Display) is a non-emissive display technology that relies on the "ight valve effect" of liquid crystal molecules to control light transmission. The liquid crystal layer is sandwiched between two polarizers, and by applying voltage to change the molecular alignment, the light transmittance is adjusted, enabling grayscale display from black to white.
2. Pixel Driving Method
The M240HTN01.2 features a resolution of 1920×1080, where each pixel consists of RGB sub-pixels controlled by individual TFTs. During line scanning, the TFT is activated to charge the pixel capacitor, which then holds the charge until the next frame refresh. This active-matrix driving method ensures stable, flicker-free performance for large-format dynamic images.
3. Backlight System Structure
It adopts an edge-lit WLED backlight system composed of LED light sources, a light guide plate (LGP), and diffusion/brightness enhancement films. The LED point light is converted into a uniform surface light through optical structures, providing stable brightness while enabling a thin panel design.
4. Signal and Driving Process
External image data is input via a 2-channel LVDS interface and processed by the T-CON (timing controller). The T-CON converts signals into timing and pixel data for the gate and source drivers. The source driver then applies corresponding voltages to each pixel, controlling the liquid crystal orientation to render the final image.
M240HTN01.2 Optical Performance
M240HTN01.2 LCD features visual clarity and long-term operational stability. Its optical characteristics are optimized for demanding professional environments where accuracy and readability are critical.
l High Definition Accuracy: It features a 1920×1080 Full HD resolution on a 24-inch screen, delivering high pixel density and clear detail. This ensures sharp rendering of labels, grids, and markings in SCADA and CAD applications, reducing reading errors.
l Brightness and Contrast: With a typical brightness of 250 cd/m², it provides reliable visibility in indoor industrial lighting conditions. A 1000:1 contrast ratio enhances black-white separation, improving overall text clarity and readability.
l Response Time and Color Performance: The display offers a 5 ms response time, reducing motion blur in dynamic scenes such as monitoring systems. It supports 16.7M colors (8-bit or 6-bit + Hi-FRC) with ~72% NTSC gamut, ensuring smooth and accurate color reproduction.
M240HTN01.2 Mechanical & Electrical Details
and electrical compatibility, enabling easier system integration and faster development.
1. Mechanical Design
The module features a 16:9 widescreen aspect ratio, aligning with mainstream industrial display and HMI requirements while ensuring broad compatibility. Its compact and slim structure reduces overall system thickness and supports both VESA mounting and embedded panel installation, making it ideal for space-constrained industrial cabinets and kiosks.
2. Interface Solution
It utilizes a mature 2-channel LVDS interface, ensuring stable and low-noise transmission of 1080P signals even over longer cable distances. The 30-pin standard connector (1.0 mm pitch) integrates power, ground, and differential signal lines, offering high compatibility with industrial motherboards and embedded platforms.
3. Backlight Structure
The panel adopts an edge-lit WLED backlight system, where light is evenly distributed via a light guide plate, reducing panel thickness and improving thermal efficiency. It also supports PWM dimming control, simplifying external circuit design without requiring complex high-voltage backlight drivers.
4. Power and Thermal Design
With a typical power consumption of around 12–15W, the module is optimized for low-power industrial use. Heat is mainly dissipated through the metal frame, allowing for passive cooling. This supports fanless system design, enhancing overall reliability and extending MTBF (Mean Time Between Failures).
