AUO G238HAN04.0 23.8 Inch FHD LCD Display – AHVA Industrial Panel
Product Overview
The AUO G238HAN04.0 is a 23.8-inch industrial-grade TFT-LCD display module manufactured by AU Optronics (AUO). This panel delivers stunning Full HD resolution (1920×1080) in a 16:9 widescreen format, making it an excellent choice for industrial control systems, medical equipment, office monitors, and embedded applications requiring high image quality and reliable performance.
Key differentiator: Equipped with AHVA (AUO Advanced wide Viewing Angle) technology—similar to IPS—this display offers full 89°/89°/89°/89° viewing angles with no grayscale inversion effect. The Normally Black mode provides deeper blacks and better contrast in dark environments. With 350 cd/m² brightness, 1000:1 contrast ratio, and 30,000-hour WLED backlight life, the G238HAN04.0 delivers exceptional visual performance for indoor professional applications.

Excellent off-axis readability — no color shift or contrast loss from any angle
Superior color consistency — accurate colors across the entire viewing cone
No grayscale inversion — unlike conventional TN panels
Normally Black mode — deeper blacks and better contrast in dark environments
2. FHD Resolution & High Pixel Density (1920×1080, 92 PPI)
The 1920×1080 Full HD resolution with 92 PPI pixel density delivers:
Crisp, detailed imagery for industrial HMI and medical imaging
Sharp text rendering for data-intensive applications
16.7M colors (6-bit + Hi-FRC) for smooth color gradations
6485K color temperature for neutral white balance
3. Excellent Image Quality (1000:1 Contrast Ratio)
The combination of 1000:1 contrast ratio and 350 cd/m² brightness ensures:
Deep blacks and vivid colors for professional applications
Clear visibility in office and indoor industrial environments
Excellent readability for long-duration viewing sessions
4. LVDS Interface for Industrial Compatibility
The dual-channel LVDS (2 ch, 8-bit) interface with 30-pin connector offers:
Stable signal transmission over longer distances
