We Welcome Your Feedback
"We are pleased that we made the decision to work with Focus Displays. The engineering staff was helpful in the design of our custom LCD module. They created the counter drawing in a few days. They were able to accommodate any changes we made and quickly modified the counter drawing. We currently purchase a few different displays from Focus and we have been happy with their service and support."
Passive displays control/refresh one row at a time. Once that row is refreshed, the control moves to the next row and so on. That means that the rows are off or not being refreshed most of the time and limits their size.
Once control moves to the next line of pixels, the brightness of the previous line of pixels fades. To fix this and provide an even light for the human eye, more power is required to increase the brightness of the pixels.
If your display has 5 rows, then you need to make the pixel 5 times brighter which equates to 5 times more power. This increased brightness reduces the display’s half-life.
Half-life is the amount of time in hours for the display to be half as bright as when first turned on. This is not the amount of time for it to burn out, but just to dim.
Even with this set back, PMOLEDs are popular because they are less costly and easier to manufacture.
