The smartphone comes with a button. If pressed, it pulls smartphone display to extend it. In regular mode, the device sports 6.75-inch AMOLED display. If the display is extended, it becomes a 7.8-inch screen.
Despite the rollable mechanism, the phone comes in just 9 mm thickness, making it practical for everyday use. TCL claims that the screen will not have any wrinkles or creases like the current generation folding smartphones. The larger axis and rolled display help in achieving a seamless experience.
TCL already has reputation for a trim-fold display that opens like an accordion and rollable display that slides out sideways windows blinds. The company believes that the display technology could be a game-changer if it’s mass-produced.
In a tri-fold device, TCL has developed two different hinge technologies of its own. Dragon Hinge and Butterfly Hinge ensure smooth folding inside and out with a minimal gap.
When it is closed, TCL’s trim-fold phone looks quite thick, the overall package looks heavy and clunky. The company’s vision is to turn a normal 6.5-inch sized device into a 10-inch tablet.
The company hasn’t shown off the final product yet. The concepts unveiled by TCL set an example of how the final product will look like. TCL hopes that it will become an innovator in the smartphone display technology.
