Embodiment Construction

[0015] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0016] Visible by Fig. 2, Fig. 3: the present invention comprises: transparent glass 1, transparent electrode 2, electrode 3 and base plate 4; Also comprise positively charged white powder 7 between transparent electrode 2 and electrode 3; There is also a black light-absorbing grid groove 8 that cuts it between the positively charged white powder 7; when it is necessary to display pictures and texts, the transparent electrode 2 is negative, and the positively charged white powder 7 rises; when it is necessary to turn the page, The transparent electrode 2 is positive, and the positively charged white powder 7 falls;

[0017] The black light-absorbing grid groove 8 can be vertical or inclined.

[0018] The black light-absorbing grid groove 8 can be realized by existing photo-etching technology.

[0019] It can be seen from Figure 4 that both the...

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 [0001] The invention relates to a display screen, in particular to an electronic paper display screen. Background technique [0002] Readers have changed from bamboo and bamboo to paper reading materials, and until the emergence of electronic computers, people can read electronic books through display screens. [0003] However, because the traditional display is projected through the backlight to display text on the display, its refraction efficiency is low, and it is easy to bring visual fatigue to the reader, which is not suitable for long-term reading, so the first thing readers often do is It should be printed on paper, because it is more convenient and comfortable to read in this way. [0004] The proposal of electronic paper solves the above-mentioned problems. E-paper itself is light and thin, and it will neither cause discomfort to readers' eyes due to the backlight like LCD screens, nor will it cause a black screen to make reading difficult due to ...
