LED display point spacing, module calculation method for the casing size and resolution. Said to point spacing, the size of the module, believe a lot of all know what it is. Can be said to be quite universal knowledge. This article mainly is the universal knowledge formulation, more convenient to learn. 1, the point spacing calculation point spacing is each pixel to each center distance between adjacent pixels. Each pixel can be a LED lights [ Such as: PH10 ( 1 r) ] , two leds Such as: PH16 ( 2R) ] , four leds [ Such as: PH16 ( 2 r1g1b) ] 。 P16 point spacing for: 16 mm; P20 point spacing for: 20 mm; P12 point spacing is: 12 mm. 。 。 2 and the distance between point and module ( Enclosure) Size of pixel points on the side of the relationship between body length = long * point spacing box body width = wide edge pixel points such as: * point spacing PH16 length 16 point x = 1. 6㎝=25. 6 ㎝, height = x 1 at 8 o 'clock. 6㎝=12. 8 ㎝ PH10 length 32 point x = 1. 0 ㎝ = 32 ㎝, height = 16 x 1. 0 ㎝ = 16 ㎝ 3, body/the calculation method of the whole screen resolution cabinet LED display resolution = length * width/point spacing per square pixels = 1000000 / spacing calculation method for using the module number 4, screen area present mould length height = present module using the module number, such as: 10 square PH16 outdoor single color LED display using module number is equal to: present 0 10 square meters. Present 0 256 metres. 128 m = 305. 17678 material 305 a more accurate calculation method: length using the module number x height using the module number = use modules such as: total of 5 meters high, 2 meters long PH16 number: use single color led display module using the module number = 5 meters long present 0. 256 m = 19. 20 high 53125 material using module for present 0 = 2 m. 128 m = 15. 16 625 material using module total number = 20 x 16 = 320 5, the LED display visual distance calculation method of RGB color mixing distance three colors blend into a single color: full color LED stadia = pixel spacing ( 毫米) X 500 - pixel spacing ( 毫米) By 1000 the minimum viewing distance can show smooth image: LED display visual range (= pixel spacing 毫米) By 1000 the best viewing distance of the viewer can see the clear picture of the highly distance: LED display best stadia = pixel spacing ( 毫米) X 3000 - pixel spacing ( 毫米) The furthest viewing distance x 1000: LED display furthest visibility = screen height ( M. ) ×30( Times)
