Full color outdoor LED display product advantage description

Outdoor full color LED display advertising advantages:

1. It is characterized by liquidity, mandatory, pertinence and effectiveness.

2, program advantages. Homemade programs, instant playback, and rich content. Not only advertising, but also programs. Including special topics, columns, variety shows, animations, radio dramas, TV series, interstitial ads.

3. Advantages of the location. It is mainly installed in shopping malls and other places where traffic is concentrated. Among them, the LED full-color large screen is installed in the landmark area, and its propagation effect is more shocking and more mandatory.

Have the following advantages

(1) Play the role of product promotion and attract customers.

(2) Play the role of store decoration and improve the grade of the company.

(3) It plays the role of lighting and unconventional.

(4) Play a role in popularizing knowledge. (Small information that can be used to play enterprise products, knowledge of related industries)

(5) Play the role of the bulletin board. (promotion, recruitment information release)

(6) Plays a role in setting off the atmosphere. Through the display screen, you can play the welcome words of the superior leaders and various VIPs to visit and guide, and the celebration words of various major festivals.

4, LED large screen common terms explained:

(1) LED brightness

The brightness of a light-emitting diode is generally expressed by Luminous Intensity in units of candela cd; 1000ucd (micro-candela) = 1 mcd (millicandela), 1000mcd = 1 cd. The light intensity of a single LED for indoor use is generally 500ucd-50 mcd, while the light intensity of a single LED for outdoor use should generally be 100 mcd-1000 mcd or even 1000 mcd or more.

(2) LED pixel module

The LEDs are arranged in a matrix or pen segment and are pre-formed into standard sized modules. The indoor display usually has 8*8 pixel modules and 8 words 7-segment digital modules. The outdoor display pixel module has specifications such as 4*4, 8*8, 8*16 pixels. The pixel module for the outdoor display screen is also referred to as a header bundle module because each pixel is composed of more than two LED tube bundles.

(3) Pixel and pixel diameter

Each LED lighting unit (dot) that can be individually controlled in the LED display is called a pixel (or pixel). The pixel diameter ∮ refers to the diameter of each pixel in millimeters. For indoor displays, one is usually a single LED with a circular shape. The indoor display pixel diameter is commonly found in ∮3.0, ∮3.75, ∮5.0, ∮8.0, etc., with ∮3.75 and ∮5.0 being the most. In an outdoor environment, in order to increase the brightness and increase the line of sight, one pixel contains more than two cluster LEDs; since two or more cluster LEDs are generally not circular, the outdoor display pixel diameter is generally expressed by the average spacing of two or two pixels. : P10, P11.5, P16, P22, P25.

(4) Point pitch, pixel density and information capacity

The center distance or dot pitch of two or two pixels of the LED display screen; the number of pixels per unit area is called pixel density; the amount of display content per unit area is called information capacity. The essence of these three is to describe the same concept: the point spacing is the distance between two pixels to reflect the pixel density, the dot spacing and pixel density are the physical properties of the display; the information capacity is the information carrying capacity of the pixel density. The unit of quantity. The smaller the dot pitch, the higher the pixel density, the more information capacity, and the closer the distance is suitable for viewing. The larger the dot pitch, the lower the pixel density, the smaller the information capacity, and the farther the distance is suitable for viewing.

(5) Resolution

The number of rows and columns of LED display pixels is called the resolution of the LED display. The resolution is the total number of pixels in the display, which determines the information capacity of a display.

(6) LED display

The LED pixel modules are arranged in a matrix according to the actual needs, and are equipped with a dedicated display driving circuit, a DC stabilized power supply, a software, a frame, and an external decoration to form an LED display.

(7) Grayscale

Gray scale refers to the degree of brightness change of a pixel, and the gray level of a primary color generally has 8 to 1024 levels. For example, if the gray level of each primary color is 256 levels, for a dual primary color color screen, the display color is 256×256=64K color, which is also referred to as a 256 color display screen.

(8) Double primary color

Most color LED displays today are dual-primary color screens, that is, each pixel has two LED dies: one for the red die and one for the green die. The pixel is red when the red die is lit, the green is green when the green die is lit, and the pixel is yellow when the red and green dies are simultaneously lit. Among them, red and green are called primary colors.

(9) full color

The red and green double primary colors plus the blue primary color form the full color of the three primary colors. Since the technology for forming full-color blue tubes and pure green dies is now mature, the market is basically full-color.
