Description

电湿润显示器及其像素阵列基板与电湿润显示像素结构 Electrowetting display pixel array and the substrate and the pixel structure electrowetting

技术领域 FIELD

[0001] 本发明涉及一种电湿润显示技术,尤其涉及一种电湿润显示器及其像素阵列基板与电湿润显示像素结构。 [0001] The present invention relates to an electrowetting display technology, particularly to an electrowetting display pixel array substrate and the electrowetting display pixel structure.

背景技术 Background technique

[0002] 图1为一种现有的电湿润显示器上视图及其局部剖面图。 [0002] FIG. 1 is a view and partial sectional view of a conventional on the electrowetting display. 参照图1,电湿润显示器10包括多个电湿润显示像素结构100,其中每一电湿润显示像素结构100包括夹于基板IOa与基板IOb之间的像素电极120、疏水性绝缘层130、油性流动介质100a、水溶液流动介质IOOb以及挡墙150。 Referring to Figure 1, an electrowetting display 10 includes a plurality of electrowetting display pixel structure 100, electro-wetting display wherein each pixel structure 100 includes a pixel electrode interposed between the substrate and the substrate IOb IOa 120, the hydrophobic insulating layer 130, an oil flow medium 100a, and an aqueous flow medium IOOb wall 150. 疏水性绝缘层130配置于像素电极120表面,且挡墙150配置于疏水性绝缘层130上,其中油性流动介质IOOa配置于疏水性绝缘层130表面,而水溶液流动介质IOOb覆盖住油性流动介质100a。 The hydrophobic insulating layer 130 is disposed on the surface of the pixel electrode 120, and wall 150 is disposed on the hydrophobic insulating layer 130, wherein the oily IOOa flowing medium disposed on the surface of the hydrophobic insulating layer 130, and an aqueous flow medium flowing medium oleaginous IOOb cover 100a .

[0003] 在图1中,每一电湿润显示像素结构100处于被施加电压的状态。 [0003] In Figure 1, each electro-wetting display pixel structure 100 is in the state a voltage is applied. 此时,油性流动介质IOOa会被排挤到挡墙150旁,水溶液流动介质IOOb则会与疏水性绝缘层130接触,其中油性流动介质IOOa与疏水性绝缘层130的接触位置大致落在每一电湿润显示像素结构100的左下方。 At this time, the flow of oil will be pushed into the medium IOOa side wall 150, the aqueous solution will be in contact with the flow medium IOOb hydrophobic insulating layer 130, the contact position wherein flow medium oleaginous IOOa with the hydrophobic insulating layer 130 each fall substantially electrically the lower left of the pixel structure 100 wetting display. 一般而言,油性流动介质IOOa为具有颜色的疏水性流动介质,而水溶液流动介质IOOb为透明的水溶液流动介质。 Generally, oily hydrophobic IOOa flowing medium flowing medium having a color, and an aqueous flow medium IOOb transparent aqueous flow medium. 因此,光线在通过油性流动介质IOOa之后会被油性流动介质IOOa所吸收而显示油性流动介质IOOa的颜色,而光线则穿透透明的水溶液流动介质100b,进而造成显示上的灰阶变化。 Thus, the light after passing through the oil flow medium IOOa flow will be absorbed by the oily medium exhibit a color IOOa IOOa oil flowing medium, and the light penetrating the transparent aqueous solution flowing medium 100B, and cause a change in the gray scale display.

[0004] 理论上,每一电湿润显示像素结构100应具有等量的油性流动介质100a。 [0004] Theoretically, each electrowetting display pixel structure 100 should have the same amount of oil flowing medium 100a. 如此一来,当电湿润显示像素结构100被施予相同电压值时,每一电湿润显示像素结构100内的油性流动介质IOOa与疏水性绝缘层130的接触面积理应相同,进而使每一电湿润显示像素结构100内的油性流动介质IOOa的膜厚也应相同。 Thus, when electrowetting display pixel structure 100 is administered to the same voltage value, the contact area of ​​each electro-wetting display IOOa oil flowing medium and the hydrophobic insulating layer 130 in the pixel 100 should have the same structure, so that each in turn is electrically wet film thickness of oil flowing medium IOOa displayed in the pixel structure 100 should be the same. 但实际上,以相同电压来驱动每一电湿润显示像素结构100来获得相同膜厚的油性流动介质IOOa却不容易。 But in fact, the same voltage to drive each of the electrowetting display pixel structure 100 to obtain an oily medium flow IOOa same film thickness is not easy. 倘若在制作电湿润显示像素结构100的过程中,因制程误差导致每一电湿润显示像素结构100中的油性流动介质IOOa的容量而有所差距,则油性流动介质IOOa的膜厚的控制便更具难度。 If the pixel structure 100 wetting display process in the production of electricity, because the process results in an error of each electro-wetting display capacity IOOa oil flowing medium in a gap between the pixel structure 100, the thickness control of the oil will flow more in the medium IOOa with difficulty.

具体实施方式 detailed description

[0031] 首先值得一提的是,在下述实施例中,电湿润显示器可以是主动式电湿润显示器或被动式电湿润显示器。 [0031] First it is worth mentioning that, in the following examples, the electro-wetting display may be active or passive electro-wetting display electrowetting display. 除此之外,本实施例的电湿润显示器可以是穿透式电湿润显示器、 反射式电湿润显示器或是半穿透半反射式电湿润显示器。 In addition, electro-wetting display of the present embodiment may be a transmissive electro-wetting display, a reflective electrowetting display or transflective electro-wetting display. 就穿透式或半穿透半反射式的电湿润显示器而言,其内可进一步设置用以提供背光源的背光模组;而就反射式的电湿润显示器而言,其可利用环境光来作为光源。 It is transmissive semi-reflective or transflective type concerned electrowetting display, the backlight module may be further provided for providing backlight therein; and for the purposes of the reflective electrowetting display, which may utilize ambient light as the light source.

[0032] 图2为本发明一实施例的电湿润显示器的局部上视剖面示意图。 [0032] Fig 2 a schematic cross-sectional view of the local electro-wetting display according to an embodiment of the present invention. 请参照图2,本实施例的电湿润显示器200包括一像素阵列基板210、一对向基板220、一流动介质230以及一流动介质240。 Referring to FIG. 2, the present embodiment electrowetting display pixel array 200 comprises a substrate 210, a pair 220, 230 and a flow medium flowing medium 240 to a substrate. 在本实施例中,流动介质230、流动介质240流动于像素阵列基板210以及对向基板220之间,且彼此不会溶解。 In the present embodiment, the flow of the medium 230, the flow medium flows in the pixel array 240 on the substrate 210 and the substrate 220 between, and does not dissolve each other. 实际上,可利用带有颜色的油性流动介质以及透明的水溶液流动介质来分别作为流动介质230以及流动介质240,但本发明不以此为限。 In practice, the use of an oil flowable medium and a colored transparent aqueous solution were used as the flow medium flowing medium flowing medium 230 and 240, but the present invention is not limited thereto.

[0033] 在本实施例中,对向基板220包括一基板222以及一共用电极224,其中共用电极224位于流动介质230以及基板222之间。 [0033] In the present embodiment, the counter substrate 220 includes a substrate 222 and a common electrode 224, wherein the common electrode 224 is located between the flowing medium 230 and substrate 222. 另一方面,像素阵列基板210包括一基板212以及多个电湿润显示像素结构300,其中电湿润显示像素结构300阵列排列于基板212上。 On the other hand, the pixel array substrate 210 includes a substrate 212 and a plurality of electrowetting display pixel structure 300, wherein structure 300 electrowetting display pixels arranged in an array on the substrate 212.

[0034] 图3A以及图3B分别为本发明一实施例的电湿润显示像素结构分别处于未被施加电压以及被施加电压两种状态下的局部上视示意图及其局部剖面图。 [0034] FIGS. 3A and 3B are respectively electrically to an embodiment of the present display pixel structures were wetted in a partial schematic top view of the lower voltage is not applied and a voltage is applied to the two states and partial sectional view of the invention. 请参照图3A,在本实施例中,每一电湿润显示像素结构300包括一像素电极320、一疏水性绝缘层330以及一挡墙350,其中疏水性绝缘层330覆盖像素电极320,而挡墙350配置于疏水性绝缘层330上。 Referring to Figure 3A, in the present embodiment, each of the electro-wetting display pixel structure 300 includes a pixel electrode 320, a hydrophobic insulating layer 330 and a wall 350, wherein the hydrophobic insulating layer 330 covering the pixel electrode 320, and the stopper wall 350 is disposed on the hydrophobic insulating layer 330. 特别值得一提的是,本实施例的挡墙350例如为一环形挡墙,其中此环形挡墙例如环绕成一矩形,但本发明不以此结构为限制。 Particularly worth mentioning is the embodiment of the retaining wall 350 is an annular wall, for example, which surrounds the annular wall, for example, into a rectangular shape, but the present invention is not restricted to the structure.

[0035] 在本实施例中,可通过像素阵列基板210中的像素电极320以及对向基板220中的共用电极224两者之间的电压差来决定流动介质230的缩放状态。 [0035] In the present embodiment, the pixel electrode by a pixel array substrate 210 and the zoom state 320 to the determined voltage difference between the two common electrode substrate 220 224 230 flow medium. 更具体地说,如图3A 所示,当无施加电压时,流动介质230可均勻地覆盖基板212。 More specifically, as shown in FIG. 3A, when no voltage is applied, the flow of the medium 230 can be uniformly cover the substrate 212. 如此,背光或环境光会被带有颜色(例如黑色)的流动介质230所吸收,使电湿润显示器200显示该颜色(例如黑色)。 Flow manner, the backlight or ambient light may be colored (e.g. black) absorption medium 230, so that the electro-wetting display 200 displays a color (e.g. black). 反之,如图3B所示,当施加电压时,亲油性的流动介质230以及亲水性的流动介质240两者之间的介面会发生极化(polarization)现象。 Conversely, as shown in FIG 3B, when a voltage is applied, the oleophilic medium 230 and the flow phenomena hydrophilic flow medium interface 240 will occur between the two polarization (polarization). 这会使亲油性的流动介质230被排挤到挡墙350旁并使流动介质230分布范围缩小。 This causes the flow of oleophilic medium 230 is pushed into the side wall 350 and 230 of the flow medium distribution narrow. 此时,背光可穿透透明的流动介质240,或者环境光可被基板212所反射,使电湿润显示器200达到显示画面的效果。 At this time, the backlight penetrable transparent fluid medium 240, or the substrate 212 may be ambient light reflected by the electro-wetting display 200 to the effect of the display screen.

[0036] 由上述可知,本实施例可通过图3A以及图3B两种状态的转换来显示画面。 [0036] From the foregoing, the present embodiment may be via a display screen and a two-state transition diagram 3B in Figure 3A. 然而, 流动介质230的膜厚会影响流动介质230吸收或反射光线之后的光学效果,进而影响显示效果以及显示品质。 However, the thickness of the flow medium 230 after the optical effect will affect the flow of medium 230 absorbs or reflects light, thereby affecting the display quality and the display effect. 为了解决因流动介质230的膜厚不均的现象,本实施例的挡墙350具有至少一开口H。 In order to solve unevenness in thickness due to the phenomenon of flowing medium 230, the present embodiment wall 350 having at least one embodiment of the opening H. 由图3B可知,通过开口H的设置,流动介质230所流动的方向为箭头所指示的方向。 Seen from FIG. 3B, an opening is provided through H, the flow direction of the medium flowing in the direction indicated by the arrow 230 in. 如此,对流动介质230而言,所有的电湿润显示像素结构300彼此连通,这可使每个电湿润显示像素结构300中的流动介质230大致具有相同的膜厚。 Thus, the flow of the medium 230, all of the electrowetting display pixel structure 300 communicate with each other, which allows each electrowetting display pixel structure 300 of the flow medium 230 has substantially the same thickness.

[0037] 更具体地说,请参照图4,在本实施例中,挡墙350具有一侧面Si、一侧面S2以及贯穿侧面Sl与侧面S2的多个开口H,其中环形挡墙350的四个墙面上例如分别设置一个用以流通流动介质230的开口H。 [0037] More specifically, referring to FIG 4, in the present embodiment, a side wall 350 having Si, S2 and a side surface side through a plurality of openings H and the side Sl and S2, wherein the annular wall 350 of the four for example, are provided on a wall for a flow of the flowing medium opening 230 H. 值得注意的是,在其他实施例中,挡墙350也可以仅具有一个开口H或在其四个墙面上分别设置多个开口H。 It is noted that, in other embodiments, wall 350 may have only one opening or H are provided on the four walls thereof a plurality of openings H. 简言之,本发明并无限制档墙350的开口H的个数。 Briefly, the present invention is unlimited number of retaining wall of the opening H 350.

[0038] 如图4所示,本实施例的开口H的高度与挡墙350的厚度相等。 [0038] As shown in FIG 4, an opening equal to the thickness H of the present embodiment, the height of the wall 350. 于是,开口H将其两侧的挡墙350完全分离开来。 Consequently, the opening H to wall 350 which completely separates the two sides. 然而,本发明并不以此为限。 However, the present invention is not limited thereto. 在其他实施例中,开口H的样貌还可以如图5所示。 In other embodiments, the opening H may also appearance shown in FIG. 具体而言,挡墙350a包括一第一部分Pl、一第二部分P2以及一第三部分P3。 Specifically, retaining wall 350a includes a first portion Pl, P2, and a second portion of a third portion P3. 其中,第一部分Pl以及第二部分P2彼此分离,且第三部分P3连接于第一部分Pl 以及第二部分P2之间并位于开口H的下方。 Wherein the first portion and the second portion P2 Pl separated from each other, and the third portion P3 is connected to and positioned below the opening H Pl between the first portion and the second portion P2.

[0039] 就传统电湿润显示技术而言,无论用何种方式将流动介质230填充于传统电湿润显示器,流动介质230的厚度的均勻性始终不易控制。 [0039] For conventional electrowetting display technology, regardless of the manner in which the flowing medium 230 is filled in a conventional electro-wetting display, thickness uniformity of the flow medium 230 is always difficult to control. 于是,不同电湿润显示像素结构内的流动介质230的膜厚便具有相当程度的差异,而光线通过不同电湿润显示像素结构的光学效果也随之不同。 Thus, different electrowetting display medium flowing in the pixel structure 230 will have a thickness of a considerable degree of difference, and the light display pixel structure of the optical effect will be different in different electrowetting. 此外,由于流动介质230的膜厚与流动介质230的接触角变化量成正比, 所以在相同的驱动电压的前提下会使不同膜厚的流动介质230具有不一致的反应速度,进而发生画面不均的情形。 Further, since the thickness of the flowing medium 230 medium 230 and the contact angle of the flow proportional to the amount of change, so will the different thickness under the same premise driving voltage flowing medium 230 has an inconsistent response speed, and thus occurrence of unevenness in the screen situation.

[0040] 然而,本实施例一改仅用来作为区隔相邻像素的传统挡墙的既有设计,而改良出具有类似连通管特性的挡墙350。 [0040] However, the present embodiment is used merely as a change in a conventional retaining wall segment pixels adjacent both design, while improving the communication tube wall 350 having similar characteristics. 即本实施例的电湿润显示像素结构300中所设置的挡墙350具有开口H,其可使流动介质230流通于所有电湿润显示像素结构300中,以解决流动介质230发生膜厚不均的情形。 I.e., electro-wetting display of the present embodiment, the pixel structure 300 wall provided with an opening 350 H, 230 which allow the flow medium flowing through the electro-wetting display all pixel structure 300, 230 to resolve a thickness unevenness of the flow medium situation.

[0041] 综上所述,本发明的电湿润显示器及其像素阵列基板中的电湿润显示像素结构的挡墙具有开口。 [0041] In summary, the electrical and electro-wetting display pixel array substrate according to the present invention, in the wall-wetting display pixel structure having an opening. 通过开口的设置,可使不同电湿润显示像素结构内流动介质的膜厚不均的情形获得解决,进而改善电湿润显示器的显示品质。 By providing openings, allows different electro-wetting display case thickness unevenness flowing medium within the pixel structure solved, thereby improving the display quality of the electrowetting display.
