Besides basic parameters like pixel pitch and size, indoor LED displays also include several other important parameters such as brightness, contrast ratio, grayscale level, and refresh rate. These parameters also have a profound impact on the visual effect of the display. Brightness is particularly important because it directly affects eye comfort during prolonged screen viewing.
The specifications mainly refer to the pixel pitch. Since indoor LED displays are used at close range, displays with a smaller pixel pitch are preferred, represented by the P-value. Available P-values include P0.9, P1.25, P1.53, P1.6, P1.8, P2, P2.5, P3, and P4. The smaller the P-value, the clearer the resolution.
