I just bought an ink screen. Does it have long service life?

The display principle of ink screen is different from all other screens.

Other displays, whether lcd, LED, organic light-emitting diode or CRT, are powered on and off, and the display disappears, and the display content is maintained by electricity. The ink screen does not consume electricity when displaying content, and only consumes electricity when the displayed content is refreshed, with little power consumption. Moreover, under the condition that the display content remains unchanged, the life of the screen is almost unaffected, and only when it is refreshed, the life is affected. The life of an ordinary ink screen is 6,543.8+0,000 times. The service life is coming, and there will be afterimage or unclear (similar to burning screen).

The refresh of ink screen is divided into partial refresh and total refresh. The local refresh is several degrees, generally tens of milliseconds to hundreds of milliseconds, the total refresh is 1-2 seconds, and the screen flashes twice. I have done an ink screen clock project before, which is refreshed locally every minute. Now the partially refreshed part feels old. And the products I bought are partially refreshed and afraid of strong light. When it is refreshed locally for several hours (hundreds of times) during the day, the display of the local refresh position becomes shallow and almost invisible, and the whole brush will get better again.

Therefore, the ink screen is suitable for weather display or electronic label (boxes of fresh horses are all ink screen price tags). The ink screen with the same content will soon break down, and it is estimated that it will be completely scrapped in about two years.
