In the rapidly evolving world of technology, LG Innotek is making significant strides in the development of the Under Panel Camera (UPC), following in the footsteps of Samsung. This innovative technology is designed to enhance the user experience by providing a full display view without any visible distractions. The UPC technology is particularly exciting as it remains invisible under normal use, becoming visible only when the front camera is activated. This advancement is not just about aesthetics; it addresses a critical challenge in smartphone design - how to offer a seamless display without compromising on camera functionality.
One of the major hurdles in implementing UPC technology is the issue of low light. Traditional under-display cameras struggle with light transmission, often resulting in lower quality images. This is a significant concern for users who rely on their smartphones for high-resolution photography. LG Innotek is addressing this challenge head-on by developing a new lens technology called the “Freeform Optic” lens.
LG Innotek makes significant progress in under-panel camera technology
This innovation aims to mitigate the loss of light that occurs when cameras are placed under the display. The key to this technology is its ability to increase light intake, thus enhancing image quality. LG's approach involves using multiple lenses, including a "free curve" shaped lens, which is instrumental in bringing in more light.
LG Innotek has been proactive in securing its advancements, having applied for several patents as early as 2021. These patents detail the optical module and the new Freeform lens technique. According to these documents, there is a recognition of the challenges posed by traditional under-display cameras - reduced brightness, image quality deterioration, and the occurrence of ghosts and flares. LG's solution lies in the application of a freeform lens, which allows for the control of the thickness of the peripheral lens. This, in turn, reduces aberration in the optical system and improves the light ratio around the optical module. The result is an enhanced image quality in the affected area.
