Today, Samsung Display posted an explanation about Samsung’s UPC (Under Panel Camera) technology on its Weibo account. In the post, Samsung said that this UPC technology eliminates the camera hole by embedding the front camera directly into the display panel. Samsung first applied this technology to the Galaxy Z Fold3.
Samsung Display’s UPC technology is realized through Eco OLED, which improves the light transmittance of the panel and optimized pixel aperture technology. The light transmittance of Eco OLED has increased by more than 33% compared with previous panels.
Existing punch-hole smartphones improve the screen-to-body ratio by placing a camera in a small hole on the panel. However, UPC technology can embed the camera module into the panel and activate it only when needed. Therefore, when the front camera is not in use, the entire display can be used fully at 100%.
Samsung Display has also adopted a technology that minimizes the color difference between the UPC hole and the surrounding screen, bringing it one step closer to achieving a full-screen.
The global certification body UL believes that according to the JNCD (Just Noticeable Color Difference) standard, the color difference between the Samsung UPC and the surrounding panel is less than 1, which means that there is no significant difference in image quality between the UPC hole area and the surrounding screen.
