G190ETN01.4 Mechanical and Optical Characteristics
Understanding the mechanical and optical characteristics of the G190ETN01.4 is equally important when selecting and designing display systems. This will help engineers with considerations for device integration and interface design.
1. Physical Dimensions and Active Area
This module features a classic 5:4 aspect ratio, providing a substantial 376.32 x 301.056 mm active display area. Its overall outline dimensions are 396.0 x 324.0 x 17.5 mm, making it a drop-in replacement for many standard 19-inch rack-mount and industrial HMI enclosures.
2. Pixel Pitch and Display Density
With a native resolution of 1280 x 1024 (SXGA), the panel offers a precise pixel pitch of 0.294 x 0.294 mm. This translates to approximately 86 PPI (Pixels Per Inch), delivering a balanced pixel density.
3. Advanced Surface Treatment
The G190ETN01.4 LCD panel is equipped with an Anti-glare (AG) surface treatment. This matte finish, combined with a 3H Hard Coating, significantly reduces specular reflections and protects the sensitive liquid crystal layer from minor scratches and environmental wear.
4. Display Mode and Visual Performance
The module operates in TN (Twisted Nematic) Mode, which is typically favored in industrial settings. It achieves a high contrast ratio of 1000:1 and a brightness of 450 nits, so the critical data always remains sharp and distinguishable.
G190ETN01.4 Display Advantages & Limitations
In this part, we will introduce the core competitive advantages of the G190ETN01.4 industrial LCD module and its limitations in specific applications.
Advantages
l High Reliability for 24/7 Operations: Its built-in backlight has a lifespan of up to 50,000 hours for consistent brightness and reliable display.
l Superior Visuals in Bright Environments: With a high brightness of 450 cd/m², the module provides clear visibility and allows operators to quickly read critical information without strain.
l Classic 4:3 Aspect Ratio: Featuring a 4:3 standard aspect ratio, the G190ETN01.4 perfectly fits legacy HMI software and financial system interfaces, enabling seamless integration without the need to redesign the UI.
l Replaceable LED Driver: The module comes with an integrated LED driver circuit, simplifying system design and integration. When needed, the LED driver can be replaced easily, enhancing maintenance and upgrade flexibility.
Limitations
l Vertical Viewing Angle (TN Panel): Using TN (Twisted Nematic) technology, this model offers slightly lower color consistency in the vertical direction compared to high-end IPS panels.
l Resolution Specificity (Classic SXGA): The SXGA resolution is tailored for industrial HMI and legacy software interfaces. When displaying 16:9 HD video, black bars may appear at the top and bottom.
