LED Display ——Not Only Lighting But Decoration

An LED display is a flat panel display, which uses an array of light-emitting diodes as a video display. An LED panel is a small display, or a component of a larger display. They are typically used outdoors in store signs and billboards, and in recent years have also become commonly used in destination signs on public transport vehicles or even as part of transparent glass area. LED panels are sometimes used as form of lighting, for the purpose of general illumination, task lighting, or even stage lighting rather than display.

Most indoor screens on the market are built using SMD technology - a trend that is now extending to the outdoor market. An SMD pixel consists of red, green, and blue diodes mounted in a single package, which is then mounted on the driver PC board. The individual diodes are smaller than a pinhead and are set very close together. The difference is that the maximum viewing distance is reduced by 25% from the discrete diode screen with the same resolution.

Indoor use generally requires a screen that is based on SMD technology and has a minimum brightness of 600 candelas per square meter (cd/m², sometimes informally called nits). This will usually be more than sufficient for corporate and retail applications, but under high ambient-brightness conditions, higher brightness may be required for visibility. Fashion and auto shows are two examples of high-brightness stage lighting that may require higher LED brightness. Conversely, when a screen may appear in a shot on a television studio set, the requirement will often be for lower brightness levels with lower color temperatures; common displays have a white point of 6500–9000 K, which is much bluer than the common lighting on a television production set.

For outdoor use, at least 2,000 cd/m² is required for most situations, whereas higher-brightness types of up to 5,000 cd/m² cope even better with direct sunlight on the screen. (The brightness of LED panels can be reduced from the designed maximum, if required.)

LED display industry in China has been developing rapidly and steadily. Increasing rate was 30%-40% in 1990s. Since entering the 21st century, it increased by 15%-20% each year. During its development, the applications of LED covered many areas of the economy, including security transaction and financial information display, airport dynamic flight information display, port and station passenger guidance information display, spots stadium information display, road traffic information display, command and control center information display, service information promotion of post, telecom and shopping center; and the fields of new products of ads and media, performance, gathering, exhibition, rental,etc. Applications in these areas formed a more stable market demand for LED. Furthermore, it keeps growing with the development.
