Definition of Viewing Angle of LED Display
The viewing angle of an LED display refers to the range of angles from which the screen can be comfortably and clearly viewed without a significant decrease in image quality or color accuracy. In other words, it indicates the maximum angle at which a viewer can watch the screen while still perceiving the displayed content accurately and without any visual distortions. As LED displays have become increasingly prevalent in various applications such as televisions, computer monitors, digital signage, and mobile devices, understanding and optimizing the viewing angle have become crucial factors in delivering a satisfying visual experience to the users. To fully grasp the concept of viewing angle in LED displays, it is essential to delve into the technology and principles underlying LED display and their optical properties. 1. Basic principles of LED displays: LED stands for Light-Emitting Diode, and it is a semiconductor device that emits light when an electric current passes through it. In an LED display, thousands or even millions of individual LEDs are grouped together to form pixels. Each pixel typically consists of three sub-pixels (red, green, and blue) that can produce various colors when they emit light at different intensities. These pixels are arranged in a matrix to form the complete display panel. 2. Impact on image quality: When viewing an LED display from the front (perpendicular to the panel's surface), the observer receives the maximum radiant intensity from the LEDs, resulting in optimal image quality. However, as the viewer moves away from the center, the angular dependence of LED emission becomes apparent, and the observed brightness decreases. Additionally, the color and contrast may also change, leading to reduced image quality and, potentially, color shifts. 3. Measuring viewing angles: The viewing angle of an outdoor or indoor LED display is typically measured in two directions: horizontal and vertical. The two angles define the co

Benefits of Variable Message Signs(VMS)
Variable Message Signs or VMS, as they are often shortened to in the industry, are a form of one-way communication between the owner and drivers or pedestrians. They are a type of light-emitting signage that can display both text and/or pictograms. You have probably seen them a lot but never realised they are defined as a Variable Message Sign. A common example is a sign over the motorway in that iconic orange LED writing saying ‘slow down’ or ‘traffic ahead’ or ‘5 minutes to junction 6’. These signs can be used to warn road users about changes in conditions ahead, alerting foot traffic of a diversion due to work, or even as part of a wider parking guidance system. You will find Variable Message Signs in a lot of different places, but the majority are outside and used to alert people of a certain event. What are the Benefits of Variable Message Signs? The benefits of a VMS are variable depending on who is implementing them, one company may think that X is the best benefit, whereas another may think it is Y. Low Power Consumption One of the overlooked benefits of a Variable Message Sign is the low cost of running it. Making it a very cost-effective piece of signage.
