    What is a Viewing Angle and why does it matter?

    2024-07-19 18:15:06  News

    The viewing angle is the angle at which the image quality of an LCD degrades and becomes unacceptable for the intended application. As the observer physically moves to the sides of the LCD display, the images on an LCD degrade in three ways. First, the luminance drops. Second, the contrast ratio usually drops off at large angles. Third, the colors may shift. The definition of the viewing angle of an LCD is not absolute as it will depend on your application.

    Most LCD panel manufacturers define viewing angle as the angles where the CR (contrast ratio)^3 10. For LCDs designed for less demanding applications, the viewing angle is sometimes defined as the angles where the CR^3 5.

    For LCD displays used in outdoor applications, defining the viewing angle based on CR alone is not adequate. Under very bright ambient light, the display is hardly visible when the screen luminance drops below 200 nits. Therefore, i-Tech defines the viewing angles based on both the CR and the Luminance.

    The way to fixed this problem is using IPS panel(also called hard screen), which has ultra viewing angle reached 178° for both vertical and horizontal direction, here are some IPS screen products: 

    43 inch outdoor IP65 waterproof LCD monitor with 4000 nits high brightness

    43 inch high brightness window facing display

    32 inch ultra thinner window facing display with 2500 nits high brightness
