Samsung Galaxy S20 or Samsung Fold 2, was earlier touted to introduce the UDC technology. Earlier rumours were suggesting that the Samsung Galaxy S21 series might finally introduce the new UDC technology. However, that is not the case after all. According to a report, South Korean media TheElec debunked the whole theory and instead claimed that the new technology might be used in the rumoured foldable device from Samsung called the Z Fold 3 is launching in the second half of 2021.
How does the Under-Display Camera technology work?
UDC allows the front camera to remain hidden under the screen of smartphones when they are not being used. This allows for a real full screen without any punch hole or notch.
Samsung Display has been using HIAA (Hole In Active Area) to implement UDC on their display screens. The company has two kinds of HIAA equipment. HIAA 1, which punches a hole on the screen in one shot. Whereas, HIAA 2 punches many micro holes.
Lately, they decided to implement HIAA 2 to develop UDC technology which was set in motion last year, and further planning to commercialize it by next year. The equipment uses Wonik IPS’ vacuum chamber and Philoptics’ laser technology.
Although, Samsung hasn’t been able to perfect the implementation as their Flexible OLED panels use yellowish Polyimide (PI) substrates, which causes the lights to distort in colour while passing through the hole. It is worth noting that the camera must also have an efficient way to hide the sensor from the display. The camera module should also be thin enough to fit in under the display.
All that remains is that Samsung might find a way to implement it soon enough. There’s no official news regarding it. We will have to wait until Samsung has perfected it as it did with the Galaxy Fold series.
