Samsung has made significant progress in the virtual reality market with Gear VR, but the screen resolution still cannot meet the needs of VR users. This is the "screen door effect."
The so-called screen door effect means that when immersing the VR experience, you will see a small black grid on the screen. And this is actually the space between each pixel, it is called the "screen door" because it is like you are watching VR content through the screen window.
Recently, in order to solve this problem, Samsung submitted a patent application called “Anti SDE AMOLED” to the European Union Intellectual Property Office.
Samsung has not announced its technical details, but Samsung will release Galaxy Note 9 on August 9. Perhaps they will also announce information related to this trademark.
