Definitions
- the invention relates to an image surface which is composed of numerous grid-like arranged pixels or pixels, each pixel having at least one color mirror which is formed by a flat, transparent chamber into which a colored liquid can be introduced.
- a pixel is the smallest picture element of a screen to which color and intensity can be assigned.
- a pixel can have three or four color mirrors arranged one above the other, to which the colors red - green - blue or the colors cyan - magenta - yellow and optionally a rear fourth color mirror are supplied in white or black.
- the pixels and color mirrors of the known image areas or displays of this type have a rectangular, in particular square shape in the image plane and are arranged next to and above one another as far as possible without spacing.
- the invention has for its object to provide an image area in which even at close inspection, the disturbing grid does not or not so strong in appearance.
- the color mirrors of the image surface should be easily electronically controllable, and the stability of the image surface formed by a plurality of transparent material and penetrated by chambers and channels should be improved.
- This object is achieved in that the color mirror in the image plane has the shape of an isosceles triangle, in particular the shape of an equilateral triangle.
- this shape of the color mirror and thus also the shape of the pixels not only has optical advantages, but also manufacturing advantages in the production of a consisting of several transparent layers Eisenflä- surface, composed of gapless juxtaposed pixels and color mirrors and of chambers, reservoirs and Interspersed with channels.
- the feed channels for the three color mirrors of the pixel can be arranged flat in cross-section and at the three different sides of the triangular pixel be.
- the invention further relates to a color mirror, which is connected to a reservoir and formed by a flat transparent chamber, wherein between the reservoir and the color mirror, a fluid flow is movable, which is composed of at least two immiscible fluids, of which a fluid is also gaseous may be and of which another fluid is a colored liquid.
- a fluid flow is movable, which is composed of at least two immiscible fluids, of which a fluid is also gaseous may be and of which another fluid is a colored liquid.
- the color mirror can be connected to the reservoir via only one channel, via which the colored liquid is supplied to the color mirror or the reservoir and at the same time clear transparent fluid is discharged.
- the channel may be flat in cross-section and its width may be at least three times its depth.
- Fig. 2 is a view according to the section line II-II in Fig. 1
- Fig. 3 is a view corresponding to Fig. 2, wherein the chamber of the color mirror only one channel for feeding and Having discharged the color liquid
- Fig. 4 is a plan view of a part of an image surface whose color mirrors are in the shape of an isosceles triangle and which are filled with three different colors;
- Fig. 5 is a plan view of a part of an image surface whose color mirrors have the shape of an equilateral triangle and which are partially filled with different colors.
- the color mirror 1 of FIGS. 1 and 2 is connected via channels 2 and 3 to a reservoir 4.
- the color mirror 1, the color in the liquid stream is supplied and discharged, wherein the color mirror 1 is formed by a flat transparent chamber and the liquid flow is composed of a first colored portion 5 and a second clear transparent portion 6, wherein the liquids of the first and the second Section are not miscible with each other and the liquid flow by means of electric wetting or a micropump between the color mirror 1 and reservoir 4 is moved.
- the color mirror 1 is connected to the reservoir 4 via only one channel 7, via which the colored liquid 5 can be supplied to the color mirror 1 or the reservoir 5 and at the same time the clear, transparent liquid 6 can be removed.
- FIGS. 4 and 5 show the screening of an image surface whose color mirrors have the shape of an isosceles triangle or equilateral triangle and which are partially filled with different colors. It can be seen that the dividing lines between the pixels are jagged and interlock. Even at close intervals, the separating lines flow into one another for the human eye, and the observer sees a homogeneous surface with the colors which the pixels receive due to the predetermined mirror filling.
