The resolution of an LED display is an important indicator of its display clarity, and its determination involves multiple factors.
First, the resolution of an LED display depends on the pixel pitch. The pixel pitch refers to the distance between the centers of two adjacent pixels, usually expressed in millimeters (mm). A smaller pixel pitch means that more pixels can be accommodated on the same display area, thereby improving resolution and display clarity. For example, a display with a pixel pitch of 1.25mm has a higher resolution than a display with a pixel pitch of 2.5mm at the same size.
Second, the physical size of the display also affects the resolution. Larger displays usually require higher resolutions to maintain a good display effect. For example, an LED display with an area of 10 square meters may have obvious graininess if the pixel pitch is large, but by reducing the pixel pitch and increasing the number of pixels, the resolution can be improved, making the image clearer and more delicate.
In addition, the viewing distance is also an important factor in determining the resolution of an LED display. If the viewing distance is far, the resolution requirement is relatively low; if the viewing distance is close, a higher resolution is required to avoid the situation where the pixels are obviously visible. For example, in indoor conference rooms, the distance between the audience and the display screen is usually close, and a higher resolution display screen is required to meet the demand for clear display; in outdoor large billboards, due to the long viewing distance, the pixel pitch can be relatively large and the resolution requirement is relatively low.
In practical applications, the type of display content also needs to be considered. If it is to display high-definition video, images or small text, etc., a higher resolution is required; if it is just to display simple graphics or text information, a lower resolution may be sufficient.
In addition, the driving method and control system of the LED Display will also affect the resolution. Advanced driving technology and control systems can better manage and control pixels, improve the stability and clarity of the display, and thus achieve higher resolution.
In short, the resolution of LED Display is determined by multiple factors such as pixel pitch, physical size, viewing distance, display content type, and driving method and control system. When selecting and designing LED Display, these factors need to be considered comprehensively to determine the resolution that best suits the actual application needs, so as to achieve the best display effect.
