Abstract
The invention relates to a display for creating coloured images and text that is visible in incident light. The screen of said display is composed of numerous pixels (1) that are arranged in a grid pattern, each pixel (1) having at least three coloured mirrors (3, 3', 3''), arranged next to one another or behind one another for the colours red, green and blue or cyan, magenta and yellow. Said mirrors are configured from flat, transparent containers, whose interiors are connected to colour reservoirs so that the contents of the latter can be displaced by control electronics in such a way that transparent coloured liquid is transported from the colour reservoirs to the coloured mirrors or vice versa. To optically highlight individual image sections, light sources (6), which are assigned to a single pixel (1), are located behind the coloured mirrors (3) of the pixels (1), each individual source being electronically controlled. A white or silver reflective layer (5), which is partially transparent or transparent for periods of time, is positioned behind the coloured mirrors (3, 3', 3'').
Description
Technical field
The present invention relates to that a kind of be used to generate can be by the coloured image of incident light identification and the display device of literal, wherein image-region is made of the pixel of a large amount of electronic controlled raster pattern settings, wherein each pixel comprises that to be used for color red, green, blue or be used for color green grass or young crops, pinkish red, the look face of yellow at least three adjacent or continuous settings, these look faces are made of flat transparent vessel and its inner room is connected with look jar (Farbreservoirs), the content of look jar can move by Electronic Control, makes Transparent color liquid move in the look face or from the look face from the look jar and moves in the look jar.
Background technology
At US 6,037,955 and US 6,747,777 and EP 1090384 in this display device is disclosed.For these from the outside by sunlight, daylight or lamplit display device according to place and time, are also wished from the formed image graph picture of back side illumination pixel.So, in EP 1090384, openly propose, at the look face rear side that constitutes by transparent material and in the front side of look jar one or more light source is set, so that the image graph picture that is made of pixel is in the dark also as seen.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of colour display device, wherein at light, especially during daylight incident, can give prominence to optically and/or color ground changes part by the formed image of controlled pixel.
The technical scheme that solves the technology of the present invention problem is, corresponds respectively to the light source of a pixel in the rear side setting of pixel color face, and these light sources of Electronic Control separately.
By this light source, can visually give prominence to the image section that daylight illuminates or change its color.Blend of colors can realize as the addition mixing by the three primary colors red, green, blue in the colour television set, perhaps as realizing by color Huang, magenta, blue or green subtraction mixing in the colour phhotograpy.
The light source of distributing to pixel especially can be white light-emitting diode.
But, light source also can by flat luminophor and be arranged on luminophor and the pixel color face between diaphragm constitute, these luminophors are from a large amount of pixels of backlighted (hinterleuchten), this diaphragm can according to pixels be controlled, and makes the light path that penetrates diaphragm according to pixels open or close more or less.
Known lighting device is particularly useful for the back lighting of big pixel region (Pixelfeld) in the flat-panel monitor, and this lighting device is made of with light emitting diode (LED) that is arranged at the light-emitting area side edge or cathode-ray tube (CRT) the light-emitting area of the leaded light of rectangle or tetragonal covering pixel region.
Diaphragm can be made of the polarization filtering mirror, and its light transmission can according to pixels be controlled by electric field.Two polarization filtering mirrors are provided with as follows and are controlled, and promptly their tissues are by the overall optical plane of oscillation.The polarization filtering mirror is a diaphragm type, and can directly be positioned on the light-emitting area.
In order to make the look face under the situation of incident daylight, produce image as well as possible, the rear side of look facial plane white or silver color is set but opaque reflection horizon, this reflection horizon is printing opacity partly or intermittently.The reflection horizon can or have lacklustre white or the glass plate or the plastic sheeting of silver color structure are made by milkiness shape (milchig-trueb) glass surface or plastic sheeting.
Reflection when improving light incident and the light transmission when improving back lighting provide a kind of the have white of stratiform or the reflection horizon of silver color pigment, and wherein pigment can be parallel to laminar surface by electric field or magnetic field or aim at perpendicular to laminar surface ground.If equally distributed floating stratiform pigment is parallel to layer plane ground and aims in liquid, then this pigment constitutes good reflection horizon, and if the layer structure of pigment and the plane of reflection extend orthogonally, then this layer is printing opacity to a great extent.
But, the reflection horizon also can be made of the jerrycan that transparent material constitutes at least one, if wherein reflection ray is wanted in this reflection horizon, then fills white or silver color color in this container, if and printing opacity is wanted in this reflection horizon, then in this container, fill Clear ﹠ Transparent liquid.
The jerrycan that is filled with white or silver color look liquid or colourless liquid can be set at the rear side of pixel region or also can according to pixels be set to the 4th look face.Under the both of these case,, display device can be worked at night by working in the daytime to be converted to by white or silver color reflection horizon being changed into the photic zone of dorsal support optical illumination.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the invention are further explained.
