Led display is driven how to scan

by:Toponetech     2021-02-04
Believe everybody scanning way of existing various series products of our company are very clear, as we all know, indoor single color products generally is 1/16 scanning, indoor full color product scan scanning scanning of 1/8, 1/16, 1/20, 1/32 scanning etc. , outdoor and the outdoor single color products are 1/4, 1/2 scanning, outdoor full-color products are static scan, 1/4, 1/6, 1/8 scanning scan. Scanning way, then, is what mean? How to understand the product half scan or a quarter of a scan? Normally, we work to display in a certain area, at the same time, light up the number of rows and the whole area in proportion to the number of rows, known as scanning way. We stick the S8 with door appearance ( Sweep a quarter) Products, for example: in general, when lit, this product is what we see to the naked eye, it is the whole board light up together. If we from the point of its working procedure, it's not, it is four times light, four line light up together every time. Thanks to the naked eye to watch, so give us a mistake it is lit up the whole plate with illusion. This phenomenon is called 1/4 scan mode. Now on the market, scan mode has two kinds of static scan and dynamic scan. How to understand static scan and dynamic scanning? Generally speaking, from the output of the driver IC feet to the practice of 'point to point' between pixels of control, this is called a static scan, called 'column point to control the dynamic scanning; Simply speaking, a static scan products, it does not need to control circuit; Dynamic scanning of the product, it is need to row control circuit, we can be very intuitive to see from the driven plate. Static scan of the product, its cost is higher, but in a good display effect and the stability of the product, and there is less brightness loss; And dynamic scanning products, it needs to control circuit, although its product cost is low, but in terms of the overall display effect is relatively static, have sent some, and brightness loss will be relatively large. 214 a led display on the constant current and constant voltage main what is the difference between the touch display brightness next why is not the same as the touch display screen have off color
