LED Brightness: Light-emitting diode (LED) êng hi a tlangpuiin luminous intensity-a tarlan a ni a, candela (cd). 1000 μCd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd-a teh a ni. Indoor LED pakhata luminous intensity chu 500 μCd - 50 mcd a ni tlangpui a, outdoor LED pakhata luminous intensity chu 100 mcd - 1000 mcd a ni tlangpui a, 1000 mcd aia sang pawh a ni.
LED Pixel Modules: LED te hi matrices emaw segment emaw ah dahin standard-sized module ah prefabricate a ni. Indoor display module hman tlanglawn tak takte chu 8x8 pixel module leh 7-segment digital module te an ni. Outdoor display pixel module hi 4x4, 8x8, leh 8x16 pixel specification-a siam a ni. Outdoor display-a pixel tin hi LED bundle pahnih emaw a aia tam emaw a awm avangin bundled module an ti bawk.
