Power estimation of LED display module

From: www.szbako.com Data:17/08/2016

1, LED display static materialized pixels (such as spacing and non spacing) :16*8 real single pixel module maximum power dissipation 16*8*3*0.015=5.7616— & mdash; 16 pixels wide. 8— & mdash; eight like pixels high. 3 & mdash; mdash; each pixel by the current; 0.015— & mdash; estimating the size of each current. Note: 2R1G1B real pixel two red LED Series in a just calculate the way current. 2LED + static virtual pixels (spacing) 2R1G1B: single module maximum power 16*8*4*0.02=7.68 16— & mdash; 16 pixels wide. 8— & mdash; 8 pixels high. 4& mdash; mdash; each pixel consists of four current; 0.015— & mdash; estimating the size of each current. Note: 2R1G1B virtual pixel two red LED separate each light tube count all the way current. 3, LED display scan image (1R1G1B) or 2R1G1B: to pitch10 four sweeps the 16 * 16 module for the cases of single module maximum power dissipation (16*16*3*0.03) /4=5.7616— & mdash; 16 pixels wide. 8— & mdash; 8 pixels high. 3 & mdash; mdash; each pixel by the current; 0.025— & mdash; estimate the size of each current; 4— & mdash; for 1 /4 scan. Note: 1R1G1B real pixel four LED tube parallel calculation of the current; scanning board each power supply is estimated to use the rate of 80%.
