摘要:
A display system for a portable device is switchable by electrical addressing. The display system can absorb ambient light and reflect at least a portion of the absorbed light to render an image on a surface of the display. The display includes a plurality of pixel electrodes. Each of the plurality of pixel electrodes includes linkers with acceptor molecules and donor molecules that form groups having respective color properties. In an off-state, a respective pixel is configured to reflect white light. In an on-state, a respective pixel is configured to reflect light according to the molecular grouping of the acceptor-donor group.
摘要:
The present invention relates to a composition and to a display device having the composition positioned between electrodes. The composition contains: (a) a compound that undergoes a reversible redox reaction to generate a pH gradient between the two electrodes, (b) an indicator dye, (c) a charge transport material, and optionally, (d) a matrix material and (e) an opacifier, and (f) secondary redox couple wherein components (a), (b), and (c) are different from one another and the standard reduction potential of component (a) is less than the standard reduction potential for the other components. Depending on the electric field present between the electrodes, a display image may be generated.

A glazing element, in particular, for facing building facades, having two nes enclosing a gaseous atmospheric intermediate space and having a predetermined layer on at least one pane surface facing the intermediate space. The glazing element is distinguished by the fact that the predetermined layer has a reactive layer applied on one pane and a catalytic layer applied on the reactive layer. The catalytic layer, depending on the composition of the gas atmosphere contained between the panes, activates in the reactive layer. The reaction changes the optical and/or electrical properties of the reactive layer, and varies the composition of the gas atmosphere in the intermediate space, thereby making the electrical and/or optical properties of the reactive layer variable.

A REVERSIBLE COLOR DISPLAY DEVICE UTILIZING A POROUS MEMBER IMPREGNATED WITH AN ELECTROLYTIC INDICATOR HAVING A PH RANGE VERY NEAR THE PH AT WHICH THE INDICATOR UNDERGOES A COLOR CHANGE. THE IMPREGNATED POROUS MEMBER IS PLACED BETWEEN A PAIR OF ELECTRODES ON OF WHICH MAY BE A WRITING ELECTRODE SUCH AS A STYLUS AND THE OTHER A BACKING ELECTRODE. UPON THE APPLICATION OF CURRENT TO THIS STRUCTURE COLOR MARKS ARE MADE ON THE POROUS MEMBER. THE COLOR CHANGE IS REVERSIBLE BY APPLYING A CURRENT OF THE OPPOSITE POLARITY TO THE DEVICE.
