Everything You Need To Know About LED Viewing Angles Of LED Wall Displays
LED wall displays have made a name for themselves in digital signage solutions by providing astonishingly vivid and clear pictures that are sure to catch your audience's attention. These display screens typically offer an impressive contrast ratio and a high viewing angle to enhance the user experience. In addition, they have excelled LED screens in cost-effectiveness, efficacy, and image delivery.
There are a ton of specifications you need to consider when buying an LED wall display, such as the backlight technology and the overall quality of the unit. If those are not enough, you also need to pinpoint factors like the viewing angle. You might be thinking about what LED viewing angle is or what factors affect these viewing angles? After viewing this article, you can pick the right one by knowing everything about the viewing angle of LED screens.
What Is The Viewing Angle?
The viewing angle of the LED wall display is an important indicator to measure the display effect and quality of the screen. There are two definitions of viewing angle. One is the angle where the brightness drops to half, and the other is the angle where the image is still recognizable and there are no visible shadows. It is generally expressed as the horizontal angle and vertical angle. The following will introduce this parameter in detail:
l Horizontal Angle
The horizontal viewing angle of the LED display screen refers to the maximum angle from which a normal view can be seen on a plane perpendicular to the display surface. If you are looking at a straight LED display, when your eyes move horizontally, you will find that the color on the screen will be distorted and eventually become black. The maximum horizontal viewing angle of humans is generally between 160°.
l Vertical Angle
The vertical viewing angle (or tilt) refers to the maximum angle from which a standard view can be seen on a line along the center of gravity of the display surface. The viewing angle is an important indicator of whether the display device has immersive visual effects – significant for LED dot matrix display devices. The maximum vertical viewing angle of an LED wall display is 140°.
Importance Of Viewing Angle For An LED Wall Display
The viewing angle of an LED display is essential, especially for outdoor LED display boards. The smaller the viewing angle, the brighter and more colorful your screen will appear from those angles. It can distinguish between a legible sign and one that looks like a blur of color when viewed from an angle. The viewing angle can make a significant difference in enhanced user experience.
The viewing angle of an LED display determines how the audience perceives a certain display. For example, installing a large outdoor LED screen as a video wall or billboard will require a wide viewing angle LED display. However, installing an indoor LED screen for a control room or studio will require a narrow viewing angle LED display.
Factors That Affect The Viewing Angle
The factors that affect the viewing angle of an LED wall display include the LED tube core package method, the module mask of the LED display, the pixel pitch, and the resolution.
1. LED Tube Core Package Method
The LED tube core packaging method is divided into SMD and DIP. The viewing angle of SMD is wider than that of DIP. The color of DIP is separated. It consists of three lamps, which block the color dispersion from different angles, resulting in a low viewing angle. The viewing angle of indoor SMD is greater than outdoor SMD, which is due to the height of the mask. The viewing angle of SMD lamp beads also varies according to the technical differences of manufacturers.
2. Module Mask
The thickness and height of the module mask will affect the viewing angle. Generally, the height of the module mask of outdoor products is higher, so the viewing angle of outdoor SMD is not as high as indoor. Similarly, the viewing angle is also affected by the expandability of the module mask due to heat.
