The joint venture LG Philips announced the completion of the next variation of the flexible display on a plastic substrate. These flexible displays use water and oil to generate images.
The developers from LG Philips managed to circumvent one of the main problems in the production of such displays, which is to achieve temperatures (required to create OLED) higher than the melting point of the plastic substrate. The solution invented by scientists is not trivial: instead of creating pixels on screens from OLED elements, they make them out of water and oil contained in small plastic cells connected to electrodes. Lightproof oil flows above water and, thereby, obscures the colored surface underneath. Applying an electric field, you can push the oil out of the water and open the colored layer under it.
The disadvantage of such a screen is that the rate of change of its state is still very low. To display a static picture, such displays can already be used, but the speaker is not yet available.
