The viewing angle of the LED full-color display depends on the viewing angle of the LED device. At present, most outdoor LED full-color displays use elliptical LEDs with a horizontal viewing angle of 100° and a vertical viewing angle of 50°, while indoor LED full-color displays use SMD LEDs with both horizontal and vertical angles of 120°. LED full-color displays on highways Due to its particularity, the screen generally uses a circular LED with a viewing angle of 30°. Some high-rise LED full-color displays have higher vertical viewing angles. The viewing angle and brightness are contradictory, and a large viewing angle will inevitably reduce the brightness. The choice of viewing angle needs to be determined according to the specific use. How to ensure the color difference consistency of LED full color display?

  The hot market of outdoor LED full-color displays has promoted the development of surface-mount full-color displays. Due to the complex installation environment, the outdoor LED full-color display has high technical requirements, not only to deal with various harsh climate changes, but also to defend against chemical gases such as automobile exhaust. A few years ago, outdoor LED full-color displays were almost all in-line. The change in this trend is due to the advancement of outdoor surface mount SMD technology. Compared with the in-line type, the outdoor surface mount full-color screen has obvious advantages in screen display, aesthetics, viewing angle, maintenance, etc., and is more suitable for outdoor use.

  The ten major development trends of LED full-color display in the future, what have you grasped? In the future, LED full-color display will continue to improve product technology, expand market space, and at the same time give full play to the advantages of energy saving and environmental protection, to achieve more beautiful and creative new applications. To sum up, the future LED full-color display will show large screen, high-definition high-density, energy-saving, intelligent, light and thin, point-by-point calibration normalization, civilianization, indoor screen outdoor, decorative landscape and display integration. , Screen enterprises concurrently run the top ten development trends of lighting. The rise and development of LED full-color display provides the basis and appeal for the super-large screen. At present, some specific markets, such as large-scale advertising business circles and large-scale amusement places, are vigorously building large-area LED full-color display screens in order to attract more attention from advertising owners and audiences.

  Cabinet calibration can greatly improve the display quality of the LED full-color display after splicing, and it has a higher efficiency than on-site calibration, is not limited by time and venue, and costs less. Therefore, the cabinet correction technology will become an indispensable part of the LED full-color display manufacturing process, and has a good application prospect. Cabinet calibration is an effective way to improve the image quality of LED full-color display. Its key technical aspects are mainly reflected in the following two aspects: one is the uniformity of pixels inside the cabinet, and the other is the consistency of brightness and chromaticity between cabinets .

  LED brightness is an important determinant of display brightness. The higher the brightness of the LED, the greater the margin of the current used, which is good for saving power consumption and keeping the LED stable. LEDs have different angle values. When the brightness of the chip is fixed, the smaller the angle, the brighter the LED, but the smaller the viewing angle of the display. Generally, a 100-degree LED should be selected to ensure a sufficient viewing angle of the display. For displays with different dot pitches and different viewing distances, a balance point should be found in brightness, angle and price.
