Launching screen technology without power

Qualcomm and a number of other manufacturers are currently working to promote the development of a new type of display technology for handheld devices and mobile devices.

According to developers, this new technology application screen is capable of displaying no power supply but just needing sunlight or movement of the device.

As a result, a mobile phone equipped with this technology application screen can continuously display all content at the request of the user, while not consuming any energy.

Most mobile phone screens today must automatically turn off when not being used to save energy. Meanwhile, the type of screen that uses new technology is illuminated by sunlight or displayed thanks to the movement of liquid in the screen.

The backlight display technique is a "killer" of energy batteries, says Mark Gostick, executive director of Liquavista, a liquid display manufacturer. Backlight technology can consume up to 90% of the screen power supply.

" The display consumes the most power of a mobile phone ," said Paul Jacobs, Qualcomm's chief executive, at the launch of his new iMod screen.

The screen on the iMod is actually a complicated mirror. Mobile image display creation. But this image will be displayed on the screen thanks to sunlight or artificial light sources around. The charge embedded in the iMod screen will ensure bright, clear images with full effect.

In low light conditions, a built-in light source will illuminate the screen. But even so, the new technology-based displays still consume less energy than today's screens, Qualcomm said.

Qualcomm's first iMod monitor only displays information in a glossy gray-white form. The company has also successfully developed a color display screen for this new screen technology, Jacos said.

Meanwhile, the screens of Liquavista are based on a technique called "charge wetting". Each of these pixels contains water and oil stains. When an electric charge is transferred to the pixels, it will have a more hydrophilic property. Water is sucked onto the screen surface, forcing the oil to reveal and color the pixels on the display. When the charge is removed, the screen becomes a water absorbent that draws water to the surface, pushing the oil away.

Thus, both companies have completed their technology. What is essential now is how to convince hardware manufacturers to apply their technology.
