The display is based on light reflection

Japan Display Japan Production Union has just introduced their latest research results: LCD panels are capable of displaying multiple colors and videos like normal but on new technology by reflecting one part of the light coming to it.

It can be said that this technology is very similar to the way e-book readers display when light shines on. Most importantly, by limiting the self-glow, the new screen panels will significantly save power during the display process and extend the usage time with the same battery capacity.

To create these LCD panels, engineers added a screen of special materials they called Light Control Laye r ( LCL bright control layer ). As explained, the original screen panel is capable of reflecting light like polished metal or glossy mirror. However, because it is made of LCD, it is integrated with electronic circuits that allow signal storage. Depending on the control state of the microchip, it allows to display different information when the light shines on.

Meanwhile, the LCL bright control layer acts as a color filter. It will disperse reflected light back in a certain way to create a color effect when projected to the user's eyes. Thus, basically the display method on the screen is quite similar to a normal reader, but the biggest difference is how it creates color. No kind of reading machine in the market can produce colors based on light reflection, to achieve that, one must use pixel light technology.

Japan Display currently expects their technology to be widely deployed soon due to its energy saving ability. They have now produced two versions of the screen on the LCL platform. The first type has the ability to reflect very high light, up to 40% of the light is transmitted back, in which only 5% of the NTSC color system is reflected. The second type, up to 36% of the NTSC color system is reflected, but the overall reflectivity is lower and at 28%. Both models have a contrast ratio of 30: 1 and the manufacturer says only one supply has a capacity of 3mW (1 mW = 1 / 1000W) to operate.
