I am using an LCD-S2X1C50TR and direct driving it with a PSoC 4200 Microcontroller. I was testing my circuit by viewing the LCD at an angle and it looked fine. Until I put my eyes directly above it, do I notice that the contrast is terrible and difficult to read.
Things I Noticed: Bringing up the supply voltage from 3V to ~4V obviously made it better, but I was curious on why it's behaving this way. The device is rated 3V~5V on DigiKey, yet at 3V, it's only visible with a side view.
Edit: I suppose DigiKey just screwed me over. Upon looking at it with other suppliers, they state a 5V supply voltage and nothing less. There was a revision to the LCD made by the company that Digikey didn't happen to update on their end. Lesson learned.
