Before anything, we have to explain what the word means bistable. A bistable circuit, as its name indicates, is a circuit that has two stable states, where we can select from a commutator switch in which we state that the circuit is. In our case, the bistable display can project the image on the screen even when you turn off the monitor. Therefore, their ability to forecast is in two states: on and off.
After this brief explanation, we can go to the subject of the text. LG presented during the Technology Fair 2011 SID a bistable display dedicated to the automakers. The screen has only 4.3 inches, and can project information such as scheduled routes and speed of the vehicle without the need to use screens with more expensive materials.
The most interesting thing about this LG screen is that it is transparent, flexible and high density of pixels, which results in a screen with an ultra low power consumption. She plays all the images in monochrome and, as we reported before, to be bistable, its image is on screen even after you turn off the monitor.
The device presented by LG is just a concept of future technology in the format of the prototype, and there is no prediction is we will see some product in the future with this type of screen, but we can not deny that it's really cool to get in the car or other devices. Below is a demonstration video made by LG, which may leave the concept more clear to readers.
