Does an LCD character display need to be constantly refreshed when something is displayed or it will it hold visible what was displayed until it is either cleared or power shut off?
For example, let’s say I display the words “Hello World”. Will I have to program that in a loop so it is refreshed every so many mSeconds or will the words stay visible until I clear the display? If it needs to be refreshed, what is a good refresh rate so the viewer doesn’t see a flicker?
Thanks…
