CSOT, the display development company of Chinese company Biggie Electronics TCL, demonstrated a number of flexible display models at CES 2021. One is a 17-inch printed OLED display and the other is a 6.7-inch AMOLED rotatable display.
Targeting large display screens such as flexible televisions, tablets, curved and foldable smartphones, and transparent commercial screens, the 17 inch OLED scroll printed screen uses the company’s proprietary inkjet printing technology. This technology does not need micro-masks. As a result, CSOT’s flexible OLED panel production cost is 20 percent less than traditional display technologies.
CSOT, which is short for China Star Optoelectronics Technology, says the panel is only 0.18mm thick and is highly scrollable and portable. The company also graded the palette to produce a 100 percent color gamut, allowing for greatly improved display quality.
CSOT displays a 6.7-inch roll-in AMOLED screen, too
Besides the 17-inch printed OLED scroll screen, CSOT also showcased a 6.7-inch rotatable AMOLED display at the mega-electronics event underway online only. This rotatable screen can extend from 6.7 inches to 7.8 inches with a simple flick of a finger.
It’s the same board we saw on TCL’s rollable smartphone prototype earlier this week. The Chinese company is preparing to launch this device by the end of this year. It believes that foldable smartphones have the upper hand over foldable smartphones in the future. Both form factors are designed to turn a smartphone into a tablet.
However, the rotatable screens allow for a much smaller footprint with a thickness of less than 10mm. This is about 2 mm thicker than the current crop of smartphones.
The rotatable CSOT screen has a special sliding mechanism that can hide or retract the panel with a simple push of a button. It has a crimp and slip radius of only 3 mm. The device can withstand up to 100,000 sliding movements.
While we have already seen several foldable smartphones arrive on the market over the past two years, we are still waiting for the world’s first commercially available foldable smartphone. However, the wait might not be long now. Besides TCL, Oppo and LG are also working on a foldable smartphone of their own. It now remains to be seen who brings it to the market first.
The flexible smartphone market continues to grow rapidly. Display market research firm DSCC (Display Supply Chain Consultants) has forecast a compound annual growth rate (CAGR) of 80 percent in foldable / foldable smartphone revenue from 2020 to 2025. The company expects revenue to exceed $ 105 billion by 2025.
