Demystifying Direct View LED: A Brief Guide to Understanding LED Specifications

October 17, 2023

Understanding the specifications of direct view LED displays is essential for selecting the right display for your specific needs, read on to find out more.

Direct view LED displays have become increasingly popular in various applications such as auditoria, digital signage, stadiums, control rooms, and corporate spaces. These displays consist of an array of light-emitting diodes that individually emit light, creating vibrant and high-resolution visuals. Understanding the specifications of direct view LED displays is crucial for making informed decisions when selecting and comparing different models.

Resolution and Pixel Pitch

Resolution refers to the number of pixels in a display, which determines the level of detail and sharpness of the visuals. Pixel pitch, on the other hand, is the distance between the centres of adjacent pixels. Smaller pixel pitches result in higher pixel density and improved image quality. For indoor applications, common pixel pitches range from 1.2mm to 3mm, while for outdoor displays, pixel pitches typically start from 3mm and can go up to 10mm or higher.

Brightness and Contrast

Brightness is a measure of the luminous intensity of a display and is usually specified in nits or candelas per square meter (cd/m²). A higher brightness level ensures clear visibility, especially in bright environments. Contrast ratio, on the other hand, defines the difference between the darkest and brightest parts of an image. A higher contrast ratio enhances image depth and detail. For indoor displays, brightness levels typically range from 800 to 2,000 nits, while outdoor displays require higher brightness levels of 2,000 nits or more.

Colour and Colour Temperature

Colour reproduction is a vital aspect of any display. LED displays should be capable of reproducing a wide range of colours accurately and consistently. Colour specifications are often described using parameters such as colour gamut and colour depth. Colour gamut refers to the range of colours that a display can reproduce, with wider gamut’s being more desirable. Colour depth, often measured in bits, determines the number of distinct colours that can be displayed. Higher colour depth results in smoother gradients and more accurate colour representation. Additionally, colour temperature refers to the perceived warmth or coolness of white light. It is usually measured in Kelvin (K). For most applications, a colour temperature of 6,500K, which represents neutral white light, is recommended.

Refresh Rate and Viewing Angle

Refresh rate refers to the number of times a display updates its image per second and is measured in Hertz (Hz). A higher refresh rate ensures smoother motion and reduces motion blur, making it crucial for applications such as sports and fast-paced content. Viewing angle indicates the maximum angle at which the display can be viewed without significant loss of image quality. Displays with wider viewing angles provide better visibility from various positions and angles.

Understanding the specifications of direct view LED displays is essential for selecting the right display for your specific needs. Resolution, pixel pitch, brightness, contrast, colour accuracy, refresh rate, and viewing angle are all key factors to consider when evaluating different models. By paying attention to these specifications, you can ensure that the LED display you choose meets your requirements and delivers outstanding visual performance in your intended application.
