First, the improvement of contrastContrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer the image and the more vivid the colors. High contrast is of great help to the sharpness, detail and gray level of the image. In some black and white contrast text and video displays, high-contrast led displays have advantages in black and white contrast, sharpne

LED display is currently a commonly used commercial lighting fixture. It can not only play the role of commercial lighting, but also can be used as advertising screens. Since LED displays are generally used outdoors, if they are not properly maintained, The service life will be greatly shortened. The LED display maintenance skills are actually very simple. The following editors will take you to see what major aspects

1. Hardness: The LED display adopts FPC as the substrate, and the hardness of the screen body is appropriate. 2, high life: LED display under the same working environment and time conditions, compared to normal LED display life is much higher 3. Energy saving: Compared with the traditional LED display, the energy saving of the LED display is very good, the power is low and the effect is more significant. Fo

Types ofAccording to the color of the LED used, outdoor LED display can be divided into single primary color, dual primary color and full color display. The single main LED display can be used as a text display. Each pixel uses a single-color LED, mostly red. The dual main LED display can be used as a graphic display. Each pixel consists of two red and green LED tubes. It comes in three colors: red, green and yellow.

The LED display is divided into indoor LED display, semi-outdoor LED display and outdoor LED display according to the use environment.The indoor screen area generally ranges from less than 1 square meter to more than ten square meters, with a high point density. It is used in non-sunlight or lighting environments, and the viewing distance is a few meters away. The screen body does not have the ability to seal and wat

1. High brightness: The brightness of outdoor LED display is greater than 8000mcd / m2, and the brightness of indoor LED display is greater than 2000md / m2; 2, long life: LED life up to 100,000 hours (ten years) 3. Large viewing angle: indoor viewing angle can be greater than 160 degrees, outdoor viewing angle can be greater than 120 degrees 4, the screen area can be large or small, as small as less t

Failure rateSince a full-color display consists of thousands or even hundreds of thousands of pixels consisting of red, green, and blue LEDs, the failure of any color LED will affect the overall visual effect of the display. Generally speaking, according to industry experience, the failure rate of the LED display before assembly starts 72 hours before shipment should not be higher than three parts per million (referr
