Samsung plans to use transparent polyimide substrate to produce foldable OLED panels to improve off-screen camera quality.

On October 9, according to foreign media reports, Samsung, a panel manufacturer owned by Samsung Electronics, shows that it has obvious advantages in small and medium-sized OLED panels such as smartphones, and they mainly supply high-end OLED panels for Apple's iPhone.

The latest foreign media reports show that Samsung, which has obvious advantages in small and medium-sized OLED panels, is considering developing OLED panels with better light transmission to improve the quality of on-screen cameras.

According to foreign media reports, Samsung plans to use transparent polyimide substrates to produce foldable OLED panels by 2024.

Foreign media said in the report that the use of fully transparent polyimide substrate to replace the currently used yellowish polyimide substrate can improve the light transmittance of the panel and then improve the shooting quality of the camera under the screen.

The off-screen camera has higher requirements for the light transmission of the panel. Samsung Electronics' Galaxy Z Fold 3 folding screen phone uses the off-screen camera, but in order to make up for the light transmission limitation of the yellowish polyimide substrate, Samsung shows that the pixels of the panel near the camera are reduced to 1877pixels per inch, only half of the 374pixels in other areas. although this measure increases the light transmission area, it also has obvious shortcomings. Even when the camera is not in use, the area where the camera is located under the screen is obviously different from other areas.

Using transparent polyimide substrates to produce OLED panels, Samsung display can increase the pixels of the panel in the area where the camera is located to match other areas.
