Description
Technical field
The present invention is about a kind of electric wet-type display, especially relevant a kind of electric wet-type display that the optics look is changed the mechanism that has.
Background technology
Figure 1A and Figure 1B are the diagrammatic cross-section of a display unit 100 of demonstration one known electric wet-type display.Shown in Figure 1A and Figure 1B, display unit 100 comprises aqueous solution 102, black ink 104 and a lipophilicity dielectric layer (hydrophobic dielectric layer) 106 of a tool polarity.Shown in Figure 1A, when not applying voltage, black ink 104 can evenly cover the upper surface of lipophilicity dielectric layer 106, so surround lighting can be absorbed and shows black and form a dark state.Otherwise shown in Figure 1B, when utilizing a voltage source 116 to apply a voltage to transparency electrode 108, interface between lipophilicity dielectric layer 106 and the aqueous solution 102 produces polarization increases effective surface energy, and so lipophilicity dielectric layer 106 promptly becomes and more do not have lipophilicity (less-gydrophobic) and make black ink 104 be pushed through partition wall 112 limits.This moment, surround lighting can be formed a bright state by bottom substrate 114 (for example being the substrate of white material) reflection and display white.This Known designs can utilize environment light source to show black and white screen and than power saving, but shortcoming shows for solid color or black and white GTG only can be provided, and can't display frame when environment light source is not enough.
Fig. 2 A and 2B are the diagrammatic cross-section of a display unit 200 of another known electric wet-type display of demonstration.Shown in Fig. 2 A, display unit 200 has aqueous solution 202, lipophilicity dielectric layer 206, transparency electrode 208, partition wall 212, and the transparency carrier 214 of tool polarity equally, and electric wet-type display utilizes a white light source 216 as backlight.This Known designs replaces black ink originally with red ink 204R, green ink 204G, blue ink 204B, utilizes a voltage source 216 to apply a voltage to transparency electrode 208 again, uses the distribution of adjusting each coloring printing ink and the purpose that reaches colorize.Yet it is good and can't show the shortcoming of black that described Known designs has color saturation.In detail, when the intensity of each coloured light of modulation, the area that colored ink covers dielectric layer 206 can change, and causes the subregion to see through the white light that white light source 216 is sent, and whole color saturation is reduced.Shown in Fig. 2 A, the saturation degree of pure blue display unit is not good because the mixed light of contiguous white light is arranged, even arround a small amount of ruddiness of display unit and also mixed light in the lump of green glow.Moreover, shown in Fig. 2 B, during the GTG of modulation blue light and ruddiness, have the mixed light of contiguous white light and a small amount of green glow.So described Known designs is easy to generate the problem of colour cast and color saturation decline.Moreover described Known designs can't show black, even add one in addition by the display unit that black ink constituted, equally has the mixed light interference cases of contiguous white light and causes not good black saturation degree.
Summary of the invention
The invention provides and a kind ofly have the optics look and change the mechanism so that the full-colorization electric wet-type display of good color saturation degree to be provided.
According to the design of one embodiment of the invention, a kind of electric wet-type display comprises one first transparency carrier and one second transparency carrier, a plurality of partition wall, one first liquid, one second liquid and an optics color converting layer that is provided with toward each other.A plurality of partition walls are formed between first and second transparency carrier and are a plurality of pixel cells so that electric wet-type display is separated.First liquid has polarity and is arranged at each pixel cell, and second liquid is not had polarity and light tight, and does not dissolve each other with described first liquid and be arranged at each pixel cell.The optics color converting layer is formed on first or second transparency carrier, is converted to green glow and ruddiness in order to a short-wavelength light that will be incident to electric wet-type display.
In an embodiment, first liquid is that aqueous solution and described second liquid are black ink.
In an embodiment, short-wavelength light is a blue light, and the optics color converting layer comprise at least with blue light be converted to ruddiness a first area, blue light is converted to a second area of green glow and allows one the 3rd zone that blue light passes through, and first area, second area, and the 3rd a zone corresponding pixel cell respectively.
In an embodiment, short-wavelength light is a ultraviolet light, and the optics color converting layer comprise at least with ultraviolet light be converted to ruddiness a first area, with ultraviolet light be converted to green glow a second area, and ultraviolet light is converted to one the 3rd zone of blue light, and first area, second area, and the 3rd a zone corresponding pixel cell respectively.
Design by aforementioned each embodiment, the short-wavelength light (blue light or ultraviolet light) that utilizes the tool higher-energy is an excitation source, make its energy state transition by optical excitation principle exciting light transition material (for example phosphor powder), discharge with the more low-energy visible light of tool (for example ruddiness or green glow) more subsequently and get back to ground state, can obtain required different visible light wavelength.Therefore, the arrange in pairs or groups backlight of ultraviolet light for example or blue light, directly penetrate or via after the fluorescent material conversion when backlight, ultraviolet light or blue light can be converted to trichromatic different color light, control its light amount of penetrating with the black ink in the moistening structure of electricity as the optical gate switch again, can obtain the effect of full-color demonstration.
Compare with Known designs, the design of above-mentioned each embodiment can be simplified the element technology of technicolo wet-type display, and can avoid the mixed light interference problem of white light or other coloured light and obviously promote color saturation, and utilize lighttight black ink can provide complete black display effect as the optical gate switch.
