 @Unabart @sandofsky This is unfortunate for you that you need a car and that they use screens with polarised light so many sunglasses can render them unusable. Unfortunately, this issue does not disappear with OLED. Of course this can be avoided with another type of sunglasses, but that can be quite expensive when you need special ones tailored to your eyes. BTW thanks for reminding me of this issue. I would have missed that otherwise. 8 comments
@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. @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.) |

@prefec2 @sandofsky I don’t have polarized glasses. I can see everything as intended!
