One article get the skills to identify high-quality LED displaysTIME:2016-7-5 1:21:44 PV:1155
These days, everything has to be graded Even the LED display can't hide...... With the continuous development of the industry, the breakthrough of technology, and the vigorous promotion of applications, the development of LED display screens in my country is becoming more and more mature. Any product has high or low quality, and LED display is no exception. Now that it is said that LED displays are also classified into grades, how is the quality identified? We mainly identify the following aspects:
Pixel out-of-control points are divided into blind dots and constant bright spots. With the birth of small-pitch screens, the industry standard can no longer be applied to small-pitch screens. The standard should be higher, and the out-of-control rate should be controlled below 1X10-5。
The protection level is mainly waterproof and dustproof. The larger the IP value is, the higher the protection level is; the safety is mainly reflected in the leakage current. The value is under the condition of U X1.1 times, and the leakage current to the ground is ≤3.5mA; The second is the dielectric strength, no insulation breakdown under the test conditions of 1,500V, 1min。
In order to reduce the power consumption of the display screen and improve the effective utilization rate of energy, thereby reducing the temperature of the LED display screen and prolonging its service life, the temperature drops by 10°C, and the life of the product is doubled, mainly achieved in the following aspects:
Even if a display screen has excellent display effect, if its reliability is not high and the failure rate of instability is high, the quality of this display screen is also very low. In order to improve its reliability, the following aspects should be considered:
After knowing the quality level of LEDs, when we purchase an LED display in the future, we can identify the quality of the LED display by considering the performance of the above aspects, and choose a cost-effective product. |
