Currently, ledp10 module, a small pitch LED display is still in the development stage of the rise, as in the actual purchase, the user should not blindly chasing the trend and ignore the other factors. A cost-effective small pitch LED system is the joint effect of many factors, modules, and paper emphasizes three aspects, modular power supply, it is an object in the user application in the purchase of focus. When we install LED display, how to calculate the LED display advertising screen size, how to select the appropriate location to install? That is nice to achieve eye-catching effects and enhance the overall image of the root causes of unevenness are: inconsistency LED performance parameters; the display in the production, installation process of assembling lack of precision; electrical parameters consistent with other electronic components It is not enough; module, PCB design is not standardized. The "inconsistent with the performance parameters of the LED" is the main reason. These inconsistent performance parameters include: light intensity is inconsistent, the optical axis is inconsistent, inconsistent color coordinates, inconsistent color light intensity distribution curve of each group and damping characteristics inconsistent. led module | Module | Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd.
