How To Ensure The Stability of Transparent LED Electronic Screens Full colour LED display pixel out of control is a rather common issue. What's the cause of this phenomenon and how to solve it? Now Lianchengfa Xiaobian (www.lcf-led.cn) and everyone came together Examine it.

Analysis of Pixel Out-Of-Control Reasons For Full-Color LED Display

The Thistle House pixel from control of the LED display means the tiniest imaging device (pixel) of this screen is not working properly. The ratio of out-of-control pixels to the total number of full-screen pixels is known as the"out-of-control pixel management speed". There are two varieties of pixel out-of-control mode. When it ought to be glowing, it isn't bright, which is called the blind spot. The second is that the constant bright spot. It's a constant highlight.

Generally, the typical LED display pixel composition is 2R1G1B (2 red bulbs, 1 green mild and 1 blue light, the same reasoning below) and 1R1G1B, and from control is usually not the exact same red, green, The blue lights are all out of control at the same time, but provided one of those lights is out of control, we

believe the pixel is out of control. Therefore, it can be concluded that the chief reason for the out-ofcontrol pixels of full-color LED screen screens is the out-of-control LED lights. The main reasons for the failure of LED lights can be divided into two elements: one is the poor quality of the LED itself; another is the improper use of the LED.

LED lights from control can not be found in the normal inspection evaluation of LED. Under acute conditions like high temperature, low temperatures, and quick temperature fluctuations, it's caused by the difference in thermal expansion coefficients of LED chips installation, epoxy resin, mounts, internal leads, die-bonding adhesives, PPA cups along with other substances, resulting in different internal stresses. The mechanics that LEDs get out of control due to electrostatic discharge is very complex.

Equipment, tools, utensils, and the body may carry static power and discharge it. This stationary power ranges from hundreds of volts to tens of thousands of volts. The discharge time is in the nanosecond level. . If the blue-green tubing is out of control, it's often that the Professional LED business -PN intersection is obscured by electrostatic discharge. As a result of complicated manufacturing process of LED display screens, electrostatic discharge cannot be prevented. Thus, electrostatic protection should run through the whole production procedure.

The Thistle House In various events, the real requirements for pixel out-of-control speed are distinct. Full-color LED screen indicators are needed to be controlled within one percent; monochrome LED screen indicators service provider are required to be controlled inside one-tenth. At the moment, there's absolutely no good alternative for full color LED display pixels. It is encouraged to contact the service maker to come back to the factory for repair. If the repair cost is too high, you can think about replacing the defective module unit plank.

At the moment, national LED displays are subject to aging tests prior to leaving the mill. The LED lights roughly of out-of-control pixels have been repaired and replaced. The"out-of-control pixel management speed" is controlled within 1/104 and the"out-of-control pixel control rate" is controlled at 3 / It is no problem inside 104, as well as some producers' business standards require that out-of-control pixels aren't permitted before leaving the mill, but this may inevitably increase the components producer's production and maintenance costs and extend the delivery time.
