Features and advantages of LED display screen

1. The advantages of LED display screen (compared with traditional LCD) are as follows:

1. Area extensibility: it is difficult to realize seamless splicing when the LCD area is large, and the LED display screen can be extended at will and realize seamless splicing.

2. Interactive technology of LED screen-brushing machine: It can enhance the interaction between screen-brushing machine as an advertising medium and advertising audience, such as customizing touch screen and realizing cloud technology broadcast control management.

3. Display effect: LED display screen has higher brightness, wider viewing angle and better color reproduction ability than LCD screen. LED screen brushing machines are generally used in airports, shopping malls, hotels, high-speed rail, subways, cinemas, exhibitions, office buildings, etc., and the target customers have strong consumption power and great advertising value.

Second, the LED display screen mainly has the following characteristics:

1. High brightness: LED uses cold light technology, and the brightness of outdoor LED display screen is more than 8mcd/㎡, which is the only large display terminal that can be used outdoors all day; The brightness of indoor LED display screen is greater than 2mcd/㎡.

2. Long service life:? With proper current and voltage, the service life of LED can reach 1, hours.

3. Wide viewing angle: indoor viewing angle can be greater than 16 degrees, and outdoor viewing angle can be greater than 12 degrees. The viewing angle depends on the shape of LED. The screen area of the display screen can be large or small, as small as less than one square meter, and as large as hundreds or thousands of square meters;

Extended information:

1. According to the advantages of LED display screen, the precautions for purchasing LED display screen are as follows:

1. Point spacing should be as small as possible

Point spacing is the distance between the center points of adjacent pixels of LED display screen. The smaller the point spacing, the more pixels per unit area, the higher the resolution, the closer the shooting distance, and of course the more expensive it is.

2. The FillFactor is higher

The fill factor of the p>LED display screen is also called the bright area ratio, that is, the ratio of the luminous area of each pixel to the physical surface area occupied by the pixel. When viewed at close range, the picture is incoherent and incomplete, and the uneven brightness produces a grainy feeling. If the light source is limited to a small pixel surface area, the brightness of a single pixel is several times or even more than ten times that of the whole screen, which will cause a more serious harsh feeling.

3. The color temperature can be adjusted

When the studio uses the LED display screen as the background, its color temperature should be consistent with the color temperature of the lights in the studio, so as to get accurate color reproduction in shooting. According to the requirements of the program, the studio lighting sometimes uses 32K low color temperature lamps and sometimes uses 56K high color temperature lamps, and the LED display screen needs to be adjusted to the corresponding color temperature, so as to obtain satisfactory shooting results.

4. Ensure a good use environment

Only under suitable working conditions can the failure rate of the product be low during its service life. As an integrated electronic product, LED display screen is mainly composed of control panel with electronic components, switching power supply and light-emitting devices, and the life and stability of all these components are closely related to the working temperature.

2. According to the characteristics of LED display screen, the points for attention in the use process are as follows:

1. The failure rate of the product is low only under suitable working conditions during its service life. LED display screen is mainly composed of control panel with electronic components, switching power supply and light-emitting devices, and the life and stability of all these components are closely related to the working temperature. If the actual working temperature exceeds the specified use range of the product, not only its service life will be shortened, but also the product itself will be seriously damaged.

2. The threat of dust also needs more attention. Working in a dusty environment, PCB absorbs dust, and the deposition of dust will affect the heat dissipation of electronic components, which will lead to the increase of component temperature, and then the thermal stability will decrease or even lead to leakage, which will lead to burning in severe cases. Therefore, attention should be paid to keeping the LED display environment clean.
