Customers often ask questions about the viewing angle of display screens, indicating that our users attach great importance to this aspect. Today, the editor of the manufacturer of high brightness industrial LCD screens has specially compiled some information about the viewing angle for everyone to better understand the knowledge about the viewing angle of industrial display screens, hoping to be helpful to everyone.
Industrial display screens, due to their physical characteristics, have different levels of clarity and quality when users observe the screen content from different directions and angles. Compared to when viewed from the front, when viewed diagonally, when the image quality has changed to an unacceptable critical angle, it is called the viewing angle of the monitor, and there are three definitions of viewing angle.
1. Comparison
If viewed from an oblique angle, a bright industrial LCD screen will appear darker on a white background and brighter on a black background compared to when viewed from the front, resulting in a decrease in contrast. The general definition is that the angle at which the contrast drops to 10 is the perspective of the industrial display. When the definition is greater than this perspective, black and white are no longer easily distinguishable. This is the most commonly used definition of perspective in the specifications of panel manufacturers and monitor manufacturers.
2. Grey scale inversion
In theory, industrial displays ranging from zero grayscale (black) to two to five grayscale (white) should have a brighter grayscale as the number of grayscales increases. However, at a large angle, industrial displays may see a lower grayscale brighter than a higher grayscale, which is a phenomenon similar to black and white reversal. This phenomenon is called grayscale reversal, which defines the maximum angle at which grayscale reversal does not occur as the viewing angle, Beyond this angle, it is possible to see grayscale inversion, which is an unacceptable image quality.
3. Color difference
Looking at a high brightness industrial LCD screen from different angles, one will find that the color changes with the angle, such as the originally white screen becoming more yellow or blue, or the color becoming lighter, and so on. As the angle increases, when the color change has reached an unacceptable critical point, the angle is defined as the viewing angle.
