Said screw 2 is used to show two kinds of colors;
Said display is according to the demonstration task, and the screw in the control electrophoresis liquid bath shows the current display color that needs.
In the display that the embodiment of the invention provides; Because screw only need show two kinds of colors, so 2 need of screw are provided with two viewing areas and show corresponding color in its spheroid, thereby can reduce the production technology of screw; And technology maturation, with low cost.
The light that the related screw 2 of the embodiment of the invention is sent can be the light that himself sends; Also can be the light of its reflection, promptly the embodiment of the invention related display can be the active illuminating type (display self produces light source, and be good more in dark more local display effect; Like LCD; Related screw 2 can be a printing opacity in the active illuminating escope, and the electrode in the electrophoresis liquid bath 1 also can be printing opacity, like this; Can light source be arranged at the electrode below, play the effect backlight that is similar to.In addition, the light source in the display also can be arranged in the spheroid of screw 2, perhaps is arranged at the outer position of spheroid of screw 2; But no matter where light source is arranged at, all requires the light of light source only to shine the zone at the current color place that needs to show on the spheroid of screw 2) and reflection-type (display self does not send light source, and light source is a surround lighting; Reach the demonstration purpose through reflection; Under high light, show obvious more, like Electronic Paper) etc.
The screw 2 that the embodiment of the invention is related; Only be used to show that two kinds of colors are color; Be similar to the ripe black and white screw of prior art, but the screw 2 in the embodiment of the invention also not only shows two kinds of colors of black and white, but can show multicolour; For example red (R) in three pigments, green (G), blue (B), even can also be yellow (Y), white colors such as (W).And screw 2 can utilize the half the of its spheroid, and promptly hemispherical area shows in two kinds of colors, and for example, screw 2 can be colors such as R for episphere, and lower semisphere is colors such as G.In optional embodiment of the present invention, screw 2 also can utilize the spheroid zone less than hemisphere to show a color.
The color that screw 2 is shown in the embodiment of the invention can satisfy pixel requirements such as three looks, four looks, the five colors or six looks.
The display that the embodiment of the invention provides; Can the different rotary ball 2 in the electrophoresis liquid bath 1 be provided with two kinds of different display colors; And according to the demonstration task that will realize; Screw in the control electrophoresis liquid bath shows the current display color that needs, and utilizing pixel is that working in coordination with between the screw 2 realized the colorize that screw 2 shows.
In the embodiment of the invention, the color layout on the screw 2 can adopt layout type such as bar shaped or alternating expression, below, with R, G, B three primary colors three color pixels are that example is explained:
Said bar shaped layout can be similar with existing conventional pixel layout, specifically can be as follows:
R?G?B?R?G?B
R?G?B?R?G?B
R?G?B?R?G?B
Said alternating expression layout specifically can be as follows:
R?G?B?R?G?B
B?R?G?B?R?G
G?B?R?G?B?R
From above two are given an example, can find out; In the more excellent embodiment of the embodiment of the invention; Screw 2 current every kind of colors that show can be surrounded by other two kinds of colors (being the color of adjacent screw 2 current demonstrations) respectively; In the better implement scheme, the embodiment of the invention can also adopt a kind of pattern that is alternately occurred like redness and green tint by the pixel primary colors, to transmit the essential information of pixel.Blue pixel only provides the chrominance information of low resolution, and this and people's visual characteristic adapts.
If adopt the layout format of onesize RGB stripe shape layout as sub-pixel, owing to receive the restriction of addressing mechanism, addressing capability only can be brought up to twice; If adopting alternating expression is the layout format of corrugated tile array (Pantile Matrix) as sub-pixel, then, can improve 4 times altogether laterally doubling with vertically all making addressing capability.In addition, alternating expression subpixel layouts form also has another advantage, and promptly its figure of appearing approaches the rotatory symmetry; Therefore, if use it for wheeled apparatus, then display screen can rotate easily; Sight is looked personnel and can be watched from different directions; For other similar devices, if need come display screen to be provided according to the information that is shown for seeing the personnel that look from different directions, also very convenient.
In the embodiment of the invention, the color layout on the screw 2 is that the principle of the pixel layout of display is to be prone to realize that more high-quality shows, and based on display the demonstration task that will realize.If a zone will show same color, like the green leaf of a slice, pixel (the being screw 2) green that can both show as much as possible in the leaf region is reasonable so.Whether identical demonstration task (this moment, needs showed identical or different) and screw 2 functions (can show identical or different color, relevant) of depending on of the color that the screw 2 that the color that current screw 2 shows is adjacent shows with color on the screw 2.With RGB three primary colors pixel layout is example, and the bar shaped layout certainly will show that pure color has more advantage than alternating expression layout, enriches picture but alternating expression is easier to demonstration.General display wants to show that pure color again can the high color of display resolution; What this moment was more excellent is that each color does not repeat to distribute; And do not repeat as far as possible with the color of adjacent screw 2; Have more advantage when showing rich colors, dynamic menu like this, shield other colors when showing pure color and get final product, the color pixel demonstration that promptly only letting needs to show gets final product.So when pixel layout, convey its pixel color of joining difference as far as possible.Not only bar shaped or alternating expression of pixel layout also has triangle, five limits, hexagon in fact ... etc. layout format.
The screw 2 color layout forms that the embodiment of the invention is related, instantiation can be shown in accompanying drawing 2 to 5.From accompanying drawing 2,3, can find out, in the embodiment of the invention, can give (each screw 2 is endowed two kinds of primary colors) on the screw 2 in the pixel bars successively with the primary colors in the pixel, and primary colors recycle; Can find out from accompanying drawing 4; In the embodiment of the invention, a viewing area in also available its two the color viewing areas of screw 2 shows a kind of primary colors, and another viewing area shows a basic look; Like blueness or white etc.; And 2 of a screw is asked to show a kind of primary colors, and the primary colors in the pixel is given on the different screw 2 successively; From accompanying drawing 5, can find out; In the embodiment of the invention, two kinds of colors that the screw 2 in the pixel bars is shown, respectively at two kinds of colors that adjacent screw 2 is shown in one identical; So; Accompanying drawing 4,2 color layout of the screw shown in 5 can roughly reduce: the color that a screw 2 can show is adjacent the color that screw 2 can show and has a kind of identical color at least, and is described adjacent, can about also can be up and down or the like.Certainly, the embodiment of the invention can also comprise other color layout forms, and for example, in the embodiment of the invention, display can adopt the enamel arrangement mode of matrix of color membrane substrates in the prior art LCDs, such as bar shaped or alternating expression pixel layout form.
Can find out that through above description the display that the embodiment of the invention provides is easy to realize the pixel layout of optimizing.And, make more intelligent changeableization of layout of pixel color to reach better effect because each pixel has double-colored at least Presentation Function.With respect to prior art, the embodiment of the invention makes the spinning ball pixelation owing to having adopted, and utilizes its cooperative effect to realize technological means such as colored demonstration, has improved the display effect that screw 2 shows, has improved the dull problem of screw 2 display colors.
Because in the display that the embodiment of the invention provides; Only require that screw 2 shows two kinds of colors; Therefore, two viewing areas only need be set on screw 2 spheroids show corresponding color, so; Can suitably dwindle the spheroid of screw 2 in the embodiment of the invention, but can not cause too much influence the display effect of screw 2.Just because of the spheroid volume of the related screw 2 of the embodiment of the invention can be smaller, therefore, more screw 2 can be set in electrophoresis liquid bath 1, can increase the pixel of display, thereby make the display effect of display excellent more.
In the specific embodiment of the present invention, shown in accompanying drawing 6, display can also comprise:
Barrier bed 4 is arranged at said electrophoresis liquid bath 1 top and covers said electrophoresis liquid bath 1, and said barrier bed 4 adopts light tight material to constitute;
Said barrier bed 4 is provided with light hole 41 above said screw 2 centre ofs sphere, be used to make the light of the color that screw 2 current needs show to see through barrier bed 4, and stops that the light of the screw 2 current colors that need not show sees through barrier bed 4;
When display according to the demonstration task; Screw in the control electrophoresis liquid bath shows current when needing display color, and said display specifically can show the color of screw 2 current the needs demonstrations that appeared by light hole 41 and utilize barrier bed 4 to block the screw 2 current colors that need not show.
The display that the embodiment of the invention provides can utilize barrier bed 4 to block the screw 2 current colors that need not to show; And only show the screw 2 current colors that need demonstration through the space of reserving; Thereby can overcome the variegated phenomenon that screw 2 possibly occur, realize that display is more true to nature, the display effect of homogeneous.
In a specific embodiment of the present invention, barrier bed 4 specifically can be arranged between the screw 2 that a screw 2 is adjacent on the partition of (promptly two neighbor between), promptly utilizes the stilt of said partition as barrier bed 4.Said partition can be used for separating each screw 2 (being pixel) and preventing each pixel electrophoresis liquid 3 mixed flow.
The screw 2 that the embodiment of the invention is related; Can be immersed in the electrophoresis liquid 3 fully; Because screw 2 is when showing the color that current needs show; Spheroid part on the screw 2 of this color that need show place (hemisphere or less than the zone of hemisphere) can place screw 2 the first half, and the light of the color that this need show passes electrophoresis liquid 3 and outwards disperses.Therefore, can be in the embodiment of the invention through means such as photoetching, the position that barrier bed 4 is in directly over the screw 2 to be removed, thereby form light hole 41, the light of the color that screw 2 needs to show can outwards be dispersed through light hole 41.
In the embodiment of the invention; The size of light hole 41; Can be relevant with color region on screw 2 of screw 2 current demonstrations, also be appreciated that relevant in the size of region vertical projection on barrier bed 4 on the screw 2 with the color of screw 2 current demonstrations.In addition, the size of light hole 41 also can be formulated based on actual needs, but need guarantee that display variegated problem can not occur.
The related barrier bed 4 of the embodiment of the invention can adopt lighttight material to constitute, black photoresist for example, inorganic ceramic, perhaps other materials etc.
Because screw 2 can be the pixel in the display, the display area of itself is just very little, adds again to adopt lighttight barrier bed 4 to block the light of the screw 2 current colors that need not to show in the embodiment of the invention; Only appear the screw 2 current light that need the color of demonstration through light hole 41; This possibly reduce the display brightness of display, and makes the display effect obfuscation of display, therefore; In embodiments of the present invention, display can also comprise:
Amplifying device 5 is used to amplify the viewing area of the color that screw 2 current needs show, the viewing area of the color that is promptly shown through light hole 41.
Thereby can be through strengthening brightness and the display effect etc. that the mode of screw 2 through the viewing area of the color that light hole 41 showed increases the color of screw 2 current needs demonstrations.Like this, the display that the embodiment of the invention provided is used through barrier bed 4 and the amplifying device 5 that is provided with light hole 41, thereby can strengthen the display brightness and the display effect of display through the mode that enlarges the viewing area, and avoids occurring variegated problem.
The amplifying device 5 that the embodiment of the invention is related, it specifically can be a kind of device with light scatter function.In a specific embodiment, amplifying device 5 can be provided with daylighting face 51 at it near barrier bed 4 one sides shown in accompanying drawing 6, is used to gather the light of the color that screw 2 shown through light hole 41, like the light of the current colors that need to show of screw 2; And be provided with scattering surface 52 away from barrier bed 4 one sides, and be used for the light scatter that daylighting face 51 is gathered is gone out amplifying device 5, thus the display brightness and the display effect of enhancing display.
Among this embodiment; The size of amplifying device 5, shape can be formulated according to actual conditions; But all or part of collection of light that needs assurance that screw 2 is launched through said light hole 41; And the form through light scatter, amplify the viewing area of the color that screw 2 is shown through light hole 41.In a specific embodiment; Daylighting face 51 can be made into concave spherical surface in the amplifying device 5, and concave spherical surface covers on the screw 2 the spheroid part of the color that needs to show as far as possible, so that fully daylighting; Help amplifying device 5 like this and better realize amplifying the function of the viewing area of the color of current needs demonstration on the screw 2; Certainly can not be too big, collect the color of barrier bed 4 to avoid daylighting face 51, thereby make display variegated problem occur.Simultaneously, the curvature of daylighting face 51 can not be too little, otherwise unfavorable expansion display viewing angles.In another specific embodiment, when said amplifying device 5 horizontal positioned, the size of daylighting face 51 vertical projections is the size that area can equal light hole 41.
Amplifying device 5 can be arranged at barrier bed 4 tops, perhaps fits on the barrier bed 4.In a specific embodiment, if when amplifying device 5 is a convex lens, then the axle center of the axle center of amplifying device 5 and light hole 41 point-blank, promptly amplifying device 5 can with light hole 41 concentric settings.
Color for fear of amplifying device 5 enlarged and displayed barrier beds 4; Also can make light tight or frosted finish effect except that daylighting face 51 and the part (53 parts shown in accompanying drawing 6) the scattering surface 52 amplifying device 5, thereby avoid display to occur variegated problem once more.
Need to prove that if display is a reflection-type, then the light source of display is a natural light; So in this case, the scattering surface 52 in the amplifying device 5 can at first play the effect of daylighting face, gathers natural light; And daylighting face 51 can be used as the face of converging, and the natural light that scattering surface 52 is gathered sees through light hole 41, converges on the screw 2; The effect that is amplifying device 5 can be illuminated screw 2 at first for letting the extraneous natural light of display pass through scattering surface 52, daylighting face 51 and light hole 41.Then; When screw 2 reflection natural lights; Recur to the effect of the viewing area of amplifying the color that screw 2 shown through light hole 41 of amplifying device 5; Gather the light of the color that screws 2 are shown through said light hole 41 by daylighting face 51, the light scatter of daylighting face 51 being gathered by scattering surface 52 amplifying device 5.Foregoing description can be found out; Because being scattering surface 52, amplifying device 5 top and bottom are cambered surface with daylighting face 51; Their pair amplifier spares 5 outer entire environment light are that natural light has been done twice and converged, so it is bigger to play the brightness of the natural light on screw 2, can not influence the brightness of screw 2.Because light path is reversible, when screw 2 reflection natural lights, amplifying device 5 is equivalent to a light path means for diverging, through twice light path scattering of daylighting face 51 and 52 two cambered surfaces of scattering surface, has amplified the viewing area of the color of screw 2 current demonstrations.Be amplifying device 5 through two cambered surfaces are set, thereby can guarantee the daylighting and the reflected light process of reflective display.
In embodiments of the present invention, amplifying device 5 specifically can be the convex lens of acryl resin material, glass material or other materials.
In another specific embodiment of the present invention, shown in accompanying drawing 7, the electrophoresis liquid 3 that electrophoresis liquid bath 1 is set can also have light tight function.Display utilizes electrophoresis liquid 3 to block the screw 2 current colors that need not show and shows the color that screw 2 current needs show.
When display according to the demonstration task; Screw in the control electrophoresis liquid bath shows current when needing display color; The display that the embodiment of the invention provides blocks the screw 2 current colors that need not to show through the electrophoresis liquid 3 that employing has light tight function, and only shows the color that current needs show in the screw 2, thereby need not to be provided with under the situation of barrier bed 4; Overcome the variegated phenomenon that screw 2 possibly occur, realize that display is more true to nature, the display effect of homogeneous.
Because screw 2 is when showing the current color that needs to show, it is the top of screw 2 that the part spheroid on this color that need show place screw 2 (hemisphere or less than hemispherical area) can place the first half of screw 2.Therefore; Can be in the embodiment of the invention through the amount of electrophoresis liquid 3 in the control electrophoresis liquid bath 1; Perhaps through the modes such as height of control screw 2 in electrophoresis liquid bath 1; Electrophoresis liquid 3 is exposed in the screw 2 current color regions that need to show; And the screw 2 current color regions that need not show are immersed in the electrophoresis liquid 3, utilize electrophoresis liquid 3 to block the screw 2 current colors that need not show, thereby realize that display only shows the color of screw 2 current needs demonstrations with light tight function.
The electrophoresis liquid with light tight function 3 that the embodiment of the invention is related specifically can be the inertia chemical reagent that contains colored pigment or common electrophoresis liquid etc., and colored pigment specifically can be black etc.Also can inertia chemical reagent or common electrophoresis liquid be handled through colouring in the embodiment of the invention, make inertia chemical reagent or common electrophoresis liquid become electrophoresis liquid with light tight function.
Because screw 2 can be the pixel in the display; The display area of itself is just very little, adds again to adopt the electrophoresis liquid 3 with light tight function to block the regional light that is sent of spheroid at the current color place that need not show in the screw 2 in the embodiment of the invention, has dwindled the light-emitting zone of screw 2; And electrophoresis liquid 3 itself has other colors; Therefore this possibly reduce the display brightness of display, and makes the display effect obfuscation of display, therefore; Display among this embodiment can amplify the screw 2 current viewing areas that need the color of demonstration through amplifying device 5 is set equally
Like this, the display that the embodiment of the invention provided is used through electrophoresis liquid 3 and the amplifying device 5 with light tight function, thereby can strengthen the display brightness of display through the mode that enlarges the viewing area, and avoids occurring variegated problem.
