@prefec2 @taixzo @Unabart @sandofsky Just a demo of the effect: https://www.youtube.com/watch?v=5SIxEiL8ujA With some explanations: @gerdcastan @prefec2 @taixzo @Unabart @sandofsky do you have a link to a written explanation? @prefec2 @taixzo @Unabart @sandofsky Most OLEDs use polarizers and wave plates to reduce reflections which would otherwise come from internal components. You lose brightness (~50%), but gain contrast. This is one of the reasons why the efficiency of OLEDs is lower than one might naively hope. Here's one model: https://optics.ansys.com/hc/en-us/articles/5845197523731 (Note that the front of the display is at the bottom of the diagrams, and unfortunately the OLEDs themselves are left out.) |
@taixzo @Unabart @sandofsky honestly I did not understand why, but it seems it does. I found multiple sources pointing that out and one that explained it. Also I did not find sources which claimed the opposite. However, if someone can provide a comprehensive and understandable explanation, I would be delighted to read it.
