Embodiment
See also Fig. 1, Fig. 1 is the structural representation of the electronic color-changing face equipment of the utility model.This variable color plate is made up of with electronic-paper display screen is laminated together color filter film 5.Wherein electronic-paper display screen comprises printing opacity electrically-conductive backing plate 4, electronic ink layer 2, the driving backboard 1 of being with transparency conducting layer 3, and this driving backboard is provided with some drive electrode bars 11.Particularly, the making of above-mentioned electronic-paper display screen generally comprises following steps:
A: establish a printing opacity electrically-conductive backing plate 4, this printing opacity electrically-conductive backing plate 4 generally comprises: PET film or glass sheet and attached to the transparency conducting layer on PET film or the glass sheet 3 (generally selecting ITO coating for use);
B: on transparency conducting layer 3, form electronic ink layer 2;
C: will drive backboard 1 and carry out lamination, and drive drive electrode bar 11 on the backboard like this and just can apply electric field with transparency conducting layer 3 and carried out white and black displays to drive intervenient electronic ink layer 2 with above-mentioned electronic ink layer.
Said structure is the universal architecture of electronic-paper display screen, and the electronic color-changing face equipment of the utility model is on this basis, has set up a slice color filter film 5 and has placed on the printing opacity electrically-conductive backing plate 4 of electronic-paper display screen, binds through adhesive; This color filter film 5 includes some bar shaped colour bands of at least two kinds of colors; It can be any varicolored combination; The drive electrode 11 of driving backboard is corresponding one by one with the bar shaped colour band on this color filter film 5, and is wherein corresponding to linking to each other between a kind of drive electrode of color colour band.
Embodiment 1:
The bar shaped colour band of the color filter film 5 of above-mentioned electronic-paper display screen top can be following three kinds of colors: red, green, blue; According to the color displaying principle, these three kinds of colors are mixed as three primary colours in varing proportions, can produce other new color; On color filter film 5, the bar shaped colour band of whenever adjacent three kinds of colors of RGB is as one group of display unit, and some groups of such RGB display units are evenly arranged on the color filter film 5.Wherein the width of each bar shaped colour band generally is controlled between 0.5 millimeter to 5 millimeters best.
Accordingly, the set drive electrode 11 of driving backboard below electronic-paper display screen 1 is corresponding one by one with the RGB bar shaped colour band of color filter film 5, and each drive electrode 11 is complementary with the geomery of bar shaped colour band directly over it.With reference to figure 2, be electrical connected each other between the corresponding drive electrode with a kind of color colour band, be responsible for the driving voltage of controlling and driving electrode by driving circuit 201.
Driving voltage (drive electrode is to the ITO public electrode) can be positive voltage or negative voltage; When interconnective one group of drive electrode is positive voltage; The bar-shaped zone of electronic ink layer correspondence position can be driven to white (or black); When interconnective one group of drive electrode was negative voltage, the bar-shaped zone of electronic ink layer correspondence position can be driven to black (or white).At this moment; The bar shaped colour band of the corresponding color of the color filter film directly over the electronic ink layer white portion lights; The bar shaped colour band of the corresponding color of the color filter film directly over the black region then can not display, and like this, the bar shaped colour band that lights is owing to reflect corresponding color; Seem that this variable color plate will demonstrate a kind of color at a distance.
So, if each primary colours has only under the situation of 2 GTGs, promptly have only bright/during dark two states, the color combination of three primary colours adds up to 2 so
3=8.Be that such variable color plate can show eight kinds of colors according to the automatic conversion of the control of display control circuit 202.
If color filter film has n primary colours, each primary colours has under the situation of m GTG, and m is so just arranged
nThe color of planting combination shows.
