Advantages: better control of color consistency, pixel pitch size can be freely adjusted according to the needs of the combination; disadvantages: red, green and blue color mixing effect is not good, the angle is not large, poor control of the consistency of the angle, processing prone to ups and downs, up and down Easy to misplace.
2 indoor surface paste:
Advantages: Display color, color mixing effect, angle consistency, etc. are all the best; Disadvantages: Packaging, processing and other high cost.
3, dot matrix module:

4. The LED display project consists of the following basic components:
LED display screen body + control system + peripheral equipment + steel structure 5. Affected LED display parameters in the "five tiger generals":
Among the main photoelectric parameters of LED display screens, there are 5 tigers with brightness, viewing angle, uniformity, contrast, and refresh rate. Certainly, there are some key parameters such as gray level, brightness level, and main wavelength error of the primary colors.
The luminance of the base color is divided by intensity and it is gray level. The higher the gray level that the display can produce, the more colors and image layers are displayed. In a digital system, the ability to control the gray scale is represented by the number of gray scales. The number of gray scales indicates how much gray scale can be controlled.
