There are several kinds parameters of LED chips, including shape scale, photoelectric parameters, operating conditions, etc. So let's see how to choose it here.
Firstly, photoelectric parameters, shape scale and operating conditions are often integrated. The using purpose of led display screens is different, so the demand for the led chips is different. Field led display requires brightness of led chips, indoor led display requires commonality of led chips, and rental led display requires value for money of led chips.
In addition to the importance of brightness, wavelength, scale, and the size of the binning for led chips, we also need to know some hidden goals. Such as gathering, commonality, reliability and other factors. These factors of led chips are difficult to express on the literal goal, but it's important in the actual use for the customers.
Convergence refers to the gathering state of LED CHIP at the package end. The major led chips manufacturers are using the BIN plan, but the BIN status of the led package segment is not the same, the difference is in the collection. It is an important mission of led chip factories to reduce the occurrence of customer-based BINs and to make customers profitable.
Commonality refers to the uniformity of the manifestations. In order to make the appearance of the final appearance uniform, it is very important for the led chip factories to make strict control on wavelength, brightness, capacitance, appearance and other aspects.
The emphasis of reliability is on the use of led chips life span. Now the LED display screens are used to the South Pole and the equator, which can withstand the wind and the rain. LED displays is tough, resistant, and always new, rather than wrinkled at the beginning of installation. The good led chips provides a healthy bone for the LED display screens.
Explicit target matching function requirements, hidden targets matching quality requirements, it is LED Display Screen.
