The Measure Of The Pixel Control In The LED Colorful Display

Edit:Shenzhen Porstar Electronics Co.,Ltd  Date:Aug 11, 2017

     Each product will have some small problems, the same LED display is no exception, many people may not know that full-color LED display pixels out of control is a more common problem, but the cause of this problem is what? Pixel out of control: the pixel out of control rate is the smallest unit of the LED screen when the proportion of the abnormal work. The number of pixels out of control is the ratio of the total number of full screen pixels, which we call the whole screen pixel runaway rate. In order to avoid runaway pixels in one region, we propose the region pixel runaway rate is in the 200×200 pixel region, the number of pixels out of control is proportional to the total area pixel. This out-of-control pixel is like a discrete distribution quantization, which makes it more convenient and intuitive to glance at.LED Colorful Display
    Pixel out of control mode: Pixel out of control is generally divided into two points. A blind spot, that is what we call a blind point, the popular explanation is that when the need to light it is not bright, so called the blind point. The second is often bright spot, refers to when the need is not bright, it is just in the light, this phenomenon is called often bright spot. Normally out of control, the red, green, and blue lights in the same pixel are all out of control at the same time, but as long as one of the lights is out of control (whichever is the light), we usually put this pixel out of control. At this point someone will ask the full color LED display pixel if out of control.LED Colorful Display
    Because the LED failure in the conventional test method of LED is not detectable. Usually in the high temperature, low temperature, relative to the temperature of rapid changes in the harsh conditions, due to LED chip, stent, inner lead, solid crystal gum, PPA cups and other materials under the differences in thermal expansion, caused by the difference in internal stress. Electrostatic discharge led to the failure of the mechanism is more complex, equipment, tools, utensils and the human body are likely to have static electricity and discharge. However, if a blue-green tube fails, the LED knot is usually penetrated by electrostatic discharge. LED display because of the process of production is more cumbersome, electrostatic discharge, so in the process of electrostatic protection must penetrate the entire process of production.LED Colorful Display
    In addition, in different occasions, the actual requirements of the pixel runaway rate is not the same, Full-color LED display indicators require normal control is in 1%, monochrome LED display indicator control within One-tenth. At present, Full-color LED display pixels no better solution, the joint prudential sent here to contact your service provider, return to the plant repair, but if the maintenance costs are too high, you can consider the replacement of those who have problems in the module board to replace.LED Colorful Display
