Today, Samsung Display posted an explanation of Samsung’s UPC (Under Panel Camera) technology on its Weibo account. In the post, Samsung said that UPC eliminates the camera hole by embedding a smartphone’s front-facing camera 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 have increased the screen-to-body ratio. They punch a small hole in the panel to place the camera. However, UPC technology can embed the camera module in the panel and only operate the camera when necessary, so the entire display screen can be used 100% when the front camera is not turned on.
Samsung Display has also adopted a technology that minimizes the chromatic aberration between the UPC hole and the surrounding screen, which is one step closer to realizing 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 big difference in image quality between the UPC hole area and the surrounding screen.
