Abstract
The invention relates to an electronic paper display screen with black light absorbing cell, comprising: transparent glass, transparent electrode, electrode and baseplate, where there is positively charged white powder between the transparent electrode and the electrode; there is a black light absorbing cell to separate the white powder; when displaying graphics and texts, the transparent electrode acts as a negative pole so that the white powder rises; when needing to turn pages, the transparent electrode acts as a positive pole so that the white powder falls; and its beneficial effects: because the powder is composed of positively charged white small balls, the white balls in the places in need of displaying graphics and texts will be attracted onto the display screen and those in the rest which are black need not move so as to be able to save power all the more and the distortion ratio is low, the contrast high and the characters are clearer. And it is a desired tool suitable for users to read.
Description
Technical field
The present invention relates to a kind of display screen, relate in particular to a kind of electronic-paper display screen.
Background technology
The reader is from previous bamboo, simple reading thing to papery, and up to the appearance of robot calculator, people can pass through the display screen viewing electronic reading materials.
Yet because traditional display screen is by projection backlight, display text on display screen, its refraction efficient is low, easily bring visual fatigue in addition to the reader, be not suitable for long reading, so first thing that the reader often does will print on the paper exactly, because read more convenient, more comfortable by comparison like this.
The proposition of Electronic Paper has solved above-mentioned problem.Electronic Paper itself is light, thin, it neither can be because the reader's eyes that cause backlight be uncomfortable as LCDs, can also can not cause the distortion and the distortion of color or form because of energy-conservation or have a power failure and cause blank screen to make to read gruelling owing to the sight angle difference yet.
Existing electronic-paper display screen all is based on the mode of natural light and moves demonstration, and a kind of method of operation is wherein arranged, and as shown in Figure 1: be by globular powder, realization matrix is arranged, and finishes demonstration; Front panel is a clear glass 1, and the back is a transparency electrode 2, and the back is electrode 3 and base plate 4 again; Having between transparency electrode 2 and the electrode 3 by powder (5,6) mobile demonstrations between clear glass 1 and base plate 4 black, white 2 looks.The black powder and the electronegative white powder of positively charged between clear glass and base plate, have been enclosed; Transparency electrode is as after adding negative electricity, and black powder is just come by suction; As adding positive electricity, white powder will be inhaled, thereby forms white and black displays.
But such display mode still can be brought following problem: distortion rate, contrast, literal sharpness; And the positive and negative conversion of transparency electrode is to the requirement of electric energy.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of electronic-paper display screen with black light-absorbing grid channel, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: clear glass, transparency electrode, electrode and base plate; The white powder that between transparency electrode and electrode, also comprises positively charged; Between the white powder of described positively charged, also comprise one with its black light-absorbing grid channel of severing; When need showed picture and text, transparency electrode was negative pole, and the white powder of positively charged rises; When the need page turning, it is anodal that transparency electrode is, and the white powder of positively charged falls.
Compared with prior art, the invention has the beneficial effects as follows: because powder is the white bead of positively charged, the place that presents needs demonstration picture and text can attracted on the display screen, all the other are black, need not motion, can save electric power more like this, and distortion rate is lower, contrast is higher, and literal is more clear, is the instrument that desirable suitable user reads.

Fig. 2 is the vertical synoptic diagram of black light-absorbing grid channel among the present invention;
Fig. 3 is the synoptic diagram that black light-absorbing grid channel tilts among the present invention;
Fig. 4 is show state figure of the present invention;
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 2, Fig. 3 as seen: the present invention includes: clear glass 1, transparency electrode 2, electrode 3 and base plate 4; The white powder 7 that between transparency electrode 2 and electrode 3, also comprises positively charged; Between the white powder 7 of described positively charged, also comprise one with its black light-absorbing grid channel of severing 8; When need showed picture and text, transparency electrode 2 was negative pole, and the white powder 7 of positively charged rises; When the need page turning, it is anodal that transparency electrode 2 is, and the white powder 7 of positively charged falls;
Described black light-absorbing grid channel 8 can be vertical or tilt.
Black light-absorbing grid channel 8 can be realized by existing photoetch technology.
As seen from Figure 4: transparency electrode and bottom electrode all are the matrix fritters, and it is (positively charged or negative electricity are by showing the picture and text decision) electrically.As the picture and text that needs show, promptly the dot matrix that need present in display screen is converted to transparency electrode and is negative electricity, and low termination electrode is positive electricity; Other background parts is then opposite.Like this, the white bead 7 of positively charged is attracted on the electronegative transparency electrode, presents picture and text.After the surround lighting irradiation, the white bead reflection ray on the transparency electrode presents the texts and pictures of reading, and other light enters black light-absorbing grid channel and absorbed fully, and reflection ray not is without any demonstration.
Claims (2)
