Samsung Display said on Tuesday that it has developed a new display that can be rolled and unrolled vertically like a scroll.

Rollable Flex stands at 49mm in length but can be rolled and unrolled vertically to extend to 254.4mm, using an O-shaped axis, the display panel maker said.

The display can be used as a monitor while extended and as a portable screen device, such as a tablet or a laptop, while rolled, Samsung Display added.

Rollable Flex is one of many displays that the company plans to exhibit at SID Display Week 2023, an annual display industry conference to be held in the Los Angeles Convention Center from May 23 to 25.

Sensor OLED display is another new display that is aimed at portable devices. It can recognize fingerprints anywhere on the screen. This is different from currently commercialized displays that have fingerprint sensors as modules attached under the panel in specific areas.

Displays that can roll, slide, or stretch

Samsung Display is offering various form factors of displays that can roll, slide, or stretch.

Samsung Display said it instead embedded the light sensing sensors when the display is made to cover the whole screen.

These sensors read the OLED light reflected from the contraction and relaxation of the blood vessels inside the fingers of both hands when touched. This converts into health information that covers heart rate, blood pressure, and stress level, the company claimed.

At the conference, Samsung Display will also exhibit previously announced innovative displays, such as Flex Hybrid, which can be both folded and slid. Another display will be Flex In & Out, which can be folded both inward and outward by 360 degrees.

Samsung Display will also exhibit its latest 77-inch model QD-OLED display aimed at high-end TVs that boasts a brightness of 2,000 nits.
