Unfortunately, I'm not fluent in Spanish. Google translate has your message as:
In the high range, more and more smartphones have opted for OLED technology for their screens. We have clear examples in the LG V30, the Galaxy Note 8, the Pixel 2 XL and more recently, the iPhone X, the last one to join this list.
Having an OLED screen allows for more striking designs where the screen is clear protagonist. But are they all advantages? We talk about what we earn but we also lose with OLED screens in our phones
Is this correct?
If so, I'm not sure what your point is. I'm not currently interested in using an OLED display for the HUD. This is because I'll be able to make the LED display brighter than an OLED one. Also, I'm trying to keep this project, so a few 7/10-segment displays are all I need.
Using an OLED display might be a next step development once the initial prototype is complete...maybe.
Did you have any specific questions about this project?
