First Step: Understand the configuration parameters. The configuration is mainly related to LED tubes, chips, packaging manufacturers, etc., which will directly affect the screen refresh rate, gray level, energy saving and other performance.
| Item | PRO | Economic |
| Lamp configuration | High-quality copper wire lamp, stable quality and good consistency | Standard copper wire lamp |
| White balance brightness | >4500cd/m2 | >4200cd/m2 |
| IC configuration | Energy-saving high-brush PWM models, dynamic energy-saving high-brush PWM-SS models | The basics of light up and simple elimination. |
| Refresh Rate | 3840HZ | 1920HZ |
| Grayscale | 14-16bit | 12-13bit |
| Starting voltage | 4.2v/4.5V | 4.5V |
| After-sales service | 3 years | 1year |
| Model | P2.5、P3、P4、P5、P6、P8、P10 | P2.5、P3、P4、P5、P6、P8 |
Second Step: Determine the pixel pitch
1.Preliminarily determine the pixel pitch according to the optimal viewing distance.
Generally speaking, the viewing distance of outdoor full-color LED display is more than 8 meters. According to the formula: optimal viewing distance=pixel pitch*1.3*1000, the suitable pixel pitch can be calculated as 6mm-8mm.
2.Determine the pixel pitch combining the resolution and screen area.
| Product | 720P(1280*720) | 1080P(1920*1080) | 4K(3840*2160) | 8K(7680*4320) |
| P2.5 | 6.14m2 | 13.06 m2 | 52.22 m2 | 208.89 m2 |
| P3 | 9.32 m2 | 20.43 m2 | 79.56 m2 | 318.25 m2 |
| P4 | 14.75 m2 | 33.18 m2 | 132.71 m2 | 530.84 m2 |
| P5 | 23.55 m2 | 52.22 m2 | 208.90 m2 | 829.44 m2 |
| P6 | 41.47 m2 | 92.16 m2 | 368.64 m2 | 1474.56 m2 |
| P8 | 58.98 m2 | 132.71 m2 | 530.84 m2 | 2123.36 m2 |
Third Step: Combined with the budget, select the pixel pitch and determine the final purchase scheme.
