A LED display refers to a video display using light emitting diodes. It can be used outdoor as lighting of the store signs and billboards. Nowadays it is also used in destination signs on public transport vehicles.
A small LED display is commonly called LED panel which can also be used to construct a larger display. In addition to display functions, LED panels are also ideal for general illumination, task lighting and even stage lighting, etc.
Types
LED display panels can be divided into two types which are the conventional discrete LED panels and surface-mounted device panels. Great majority of outdoor LED display screens and some of indoor screens are built around discrete LEDs, which can be called individually mounted LEDs. Generally speaking, a full-color pixel usually consists of a cluster of red, green, and blue diodes, and these pixels are separated evenly apart and are measured from center to center for absolute pixel resolution.
On the market, vast majority of indoor LED display screens take advantage of SMD technology, and this trend is extending to the outdoor market gradually. A cluster of red, green, and blue diodes which are mounted in a single package is driven to form a SMD pixel. Then the SMD pixel will be mounted on the driver PC board. The individual diodes that are set very close together may be smaller than a pinhead.
Generally, LED display for indoor use is typically designed based on SMD technology and requires a minimum brightness of 600 candelas per square meter. However, this just meets the needs of corporate and retail applications. It features with high ambient-brightness. On the contrary, lower brightness and lower color temperature are always indispensable when a screen may appear in a flash on a television studio set.
Outdoor LED display with a minimum brightness of 2000cd/m2 is suitable for different cases, and when there is directly sunlight on the screen, the brightness of the LED display panel is higher, up to 50002000cd/m2 or above.
The factors which identify the suitable locations for large LED display panels can be varied, and it includes line of sight, local authority planning requirements, vehicular access, cable runs for power and video and so on .
