Zhangzhou Yizhong LED display --- what are the factors that consider the screen area allowed by the user's site
(1) the relationship between effective sight distance and actual site size<(2) pixel size and resolution
(3) area estimation based on cell
(4) operation space for screen mechanical installation and maintenance<(5) the influence of screen tilt angle on distance
·Zhangzhou Yizhong LED display screen --- what are the playback effects users need
(1) text display: it depends on the text size and resolution requirements
(2) general video display: 320 × 240 lattice<(3) digital standard DVD display: ≥ 640 × 480 lattice<(4) complete computer video: ≥ 800 × 600 dot matrix
· Zhangzhou Yizhong LED display --- what are the brightness requirements for the screen body

(1) indoor:> 800cd / m2
(2) semi indoor:> 2000cd / m2
(3) outdoor (facing south):> 4000cd / m2
(4) outdoor (facing south):> 8000CD / m2
· Zhangzhou Yizhong LED display --- what kind of brightness requirements do red, green and blue have in white composition the color of white is differentThe basic reason is that the human eye's retina has different light perception for different wavelengths.
after a large number of experiments, the following approximate proportion is obtained.
for reference design:
the simple red green blue brightness ratio is 3:6:1
the accurate red green blue brightness ratio is 3.0:5.9:1.1
· Zhangzhou Yizhong LED display --- why do high-end full-color displays need to be used Green tube
in the actual production of LED display screen, the three primary color
LED tubes with high luminous efficiency and rich and bright color should be selected, so that the area of color triangle in chromaticity diagram is as close as possible to the tongue spectral color curve, so as to meet the requirements of rich color

and sufficient brightness. The top of tongue curve is 515nm wavelength light, Therefore, the high-end LED display adopts the pure green LED tube whose wavelength is close to

515nm, such as 520nm, 525nm or 530nm wavelength light.

· Zhangzhou Yizhong LED display --- under the condition of clear brightness and point density requirements.
how to calculate the brightness of single tube

brightness of red LED: brightness (CD) / m2 △ points / m2 × 0.3 △ 2
brightness of green LED: brightness (CD) / m2 △ points / m2 × 0.6
brightness of blue LED: brightness (CD) / m2 △ points / m2 × 0.1
for example, if the density of 2500 dots per square meter, 2R1G1B, and the brightness of 5000 CD / m2 per square meter are required, the brightness of red LED lamp is 5000 △ 2500 × 0.3 △ 2=0.3
the brightness of green LED is 5000 △ 2500 × 0.6=1.2
the brightness of blue LED is 5000 △ 2500 × 0.1=0.2
brightness per pixel: 0.3 × 2+1.2+0.2=2.0 CD,
