摘要:
Applying the method of manufacturing a polymeric foil (30) having partly embedded inorganic particles (19) results in the polymeric foil (30) being suitable for use as a movable element (3) in a display panel (21). The method starts by embedding inorganic particles (19) partly into a release layer (32) which covers a substrate (31). This product (37) is covered with a layer of polymeric material (18), which is solidified to obtain the polymeric foil (30). By removing the release layer (32), the polymeric foil (30) having a surface with a roughness brought about by the partly embedded inorganic particles (19) is set free.

The display device (1) comprises a light transmitting first plate (2), a second plate (4) facing the first plate (2), a movable element (3) between the first plate (2) and the second plate (4) able to decouple light out of the first plate (2). The first plate (2) has a first surface (40) facing away from the movable element (3) and a second surface (14) facing the movable element (3), and electrodes (5,6,25) on the first plate (2), the second plate (4) and the movable element (3), able to locally bring the movable element (3) into contact with the first plate (2) by applying voltages to the electrodes (5,6,25). Including light absorption means (41), able to absorb light decoupled out of the first plate (2) by the movable element (3), and optical coupling means (43) at at least one of the first and second surface (40, 14) for having light directed into the first plate (2) via the first surface (40), reflected at the second surface (14) and directed out of the first plate (2) via the first surface (40), the display device (1) requires relatively little energy to be operated.

The invention relates to a display device (10) comprising a light guide (2) and a plate (4), which extend essentially parallel in a mutually spaced relationship, said display device further comprising a movable element (3) which is arranged between the light guide and the plate in a spaced relationship to the light guide, selection means (5, 6) to locally bring said movable element into contact with the light guide, and a number of spacing elements (13) arranged on the light guide or the plate for maintaining the space between the movable element and the light guide and the plate, respectively, characterized in that the spacing elements form an integral part of the movable element. The invention also relates to a method of producing the display device according to the invention.
摘要:
The invention relates to a method of controlling a display screen, particularly a foil display built up of a number of lines, the display screen comprising at least one light source, a movable element, and selection means for locally bringing the movable element into contact with the light source, in which the selection means comprise row and column electrodes and means for applying control voltage signals to the invention also relates to a display source, a movable element, and selection means for locally bringing the movable element into contact with the light source, in which the selection means comprise row and column electrodes and means for applying control voltage signals to the row and column electrodes. Because of a minimum switching time of pixels, not all pixels, i.e. lines can be activated immediately when the display screen is addressed line by line. To avoid this problem, the invention provides a novel addressing method comprising the step of addressing a group of lines or a part of a group of lines while the light source is switched off, followed by a step of illuminating the display screen for a predetermined interval by switching on the light source.
