How to choose LED full color TFT Display Module specifications

1, LED display the environment, outdoor, semi-outdoor or indoor environment is not the same, not the same water requirements. Outdoor water requirements are high, generally above IP65. According to the environment in which we can determine the approximate range of options outdoor full color display or semi-outdoor full color display, indoor full color display!lcd graphic display modules 
2, the best vantage point from the installation distance of the display, you can distance, this distance is very important, it directly determines the display model you choose, general indoor full color display models divided into P6 P7.62, P10, p12 outdoor full color display model is divided into P10, P12, P16, P20, etc., these are conventional, such as pixel screen, bar screen, shaped screen Specification is not the same, here only conventional, P behind the figure is the distance between the lamp beads millimeters, ships, we visualized the minimum distance is equivalent to the size of the number of P behind. I.e. P10 optimal spacing of 10 meters, this method is only a rough estimation!
There is also a more specific scientific method, that is the use of lamp beads density per square to count, such as the P10 dot density of 10,000 / square, the best distance equal to 1400 divided by (the square root of the density). P10 1400/10000 = 1400/100 = 14 meters square root, that the best observation P10 display the distance of 14 meters!
The above two methods directly determine the specifications of the selected LED full color display, that is, the customers at the time of purchase must pay attention to two points: 1, the display of the environment. 2, the best observation position the distance from the display position. Only by understanding these, you can choose full color LED display to match your environment to achieve the best results.lcd modules
