With the wide application of LED display in various fields, people's attention to LED display is also higher and higher. As we all know, LED display is divided into full-color screen and monochrome screen, so how should we proceed when shopping? Today, let us understand the LED display shopping tips.
First of all, we need to understand the specifications of the LED display we need. In practice, we usually choose according to the following aspects:
First, the viewing distance
Indoor and outdoor display viewing distance is different. Indoor display in the case of no lights, the general requirements for viewing distance of 2-3 meters. Due to the different indoor environment, the brightness of the display, contrast, color saturation and clarity and other indicators are different.
Such as in shopping malls and other public places, in order to achieve better visual effects, usually require LED display brightness is higher; And in some closed places, such as banking halls, securities trading halls, etc., the display contrast requirements are lower. The viewing angle of indoor LED display is generally 160°/140°, and outdoor LED display is 100° or 120°. According to the viewing distance and viewing angle of different, LED display according to the use of environment can be divided into fixed screen and mobile screen two.
Second, the installation environment
LED display installation environment mainly includes the following aspects:
1, outdoor: windy, dusty, strong ultraviolet rays, rain and snow;
2, indoor: high humidity, low temperature, easily affected by moisture;
3、Outdoor environment: humid, affected by rain and snow;
4, indoor environment: installed indoors, the brightness requirements are not high.
According to different environmental conditions to choose different specifications of the LED display.
Third, the display content
1, monochrome LED display: monochrome screen can only display a color, such as red, green, blue primary colors, or red, blue + white, or red, blue + black. Therefore, when choosing LED display, monochrome screen is generally not too much, otherwise it will lose the application value.
2, full color LED display can display any number of colors. If you want to display any one of the three primary colors of red, green and blue, you need to use color LED display.
3, monochrome screen and full color LED display compared to monochrome screen can only display monochrome, while the full color screen can display any number of colors. Therefore, when choosing LED display, should be based on specific application scenarios to determine the product color selection and control system function configuration.
Fourth, the screen specification
LED display screen specifications are: indoor and outdoor two different specifications.
General indoor LED display models: small pitch P1, P1.25, P1.37, P1.53, P1.667, P1.839, P1.86, etc., LED display prices vary according to the different models; ordinary indoor P2.0, P2.5, P3.0, P4.0, P5.0, P6.0, etc., the price of the product is arranged step by step according to the size of the pitch.
General outdoor LED display models: P2.5, P3.0, P4.0, P5.0, P6.0, P8.0, P10.0, etc., outdoor LED display prices are generally relatively high relative to the indoor price, mainly because of the high requirements of outdoor LED display, not only need to be waterproof, but also need to consider the aging of the hardware of the wind and the sun.
V. Other requirements
In addition, due to the different requirements of different fields and different occasions, so in the choice of LED display need to take into account the specific application environment, but also take into account the screen installation, whether you need to install control systems and other factors. If it is used in the outdoor environment, then you should choose the waterproof, dustproof performance of the LED display; if it is used indoors, then you should choose the moisture-proof display, the brightness is a little lower.
