电子墨水显示面板Electronic Ink Display Panel

技术领域technical field

本发明涉及一种显示面板，且尤其涉及一种电子墨水显示面板(electronic-ink display panel)。The present invention relates to a display panel, and in particular to an electronic-ink display panel.

背景技术Background technique

一般而言，目前常见的电子墨水显示装置包括一前盖板(front planelaminate，FPL)、一电子墨水层以及一薄膜晶体管阵列基板(thin filmtransistor array substrate)，其中前盖板具有一透明电极层；电子墨水层具有以带电粒子作动并具有双稳态(Bi-Stable)的显示材料(即电子墨水)。Generally speaking, the current common electronic ink display device includes a front plane laminate (FPL), an electronic ink layer and a thin film transistor array substrate (thin film transistor array substrate), wherein the front plane has a transparent electrode layer; The electronic ink layer has a bi-stable (Bi-Stable) display material (ie, electronic ink) that acts as charged particles.

以一现有技术的电子墨水层为例：带电粒子为颜色不同的正电荷和负电荷(例如：黑色和白色)且带电粒子与一透明流体包含于一微胶囊中。当薄膜晶体管阵列基板的各像素电极与透明电极层之间的电场改变时，不同颜色的正电荷和负电荷便会根据电场方向而向上或向下移动，进而使各微胶囊呈现出黑色或白色。另外，微胶囊也可包含有颜色不同的单一电荷和不透明流体(例如：黑色和白色)。薄膜晶体管阵列基板的各像素电极与透明电极层之间的电场改变时，带电粒子中的单一电荷便会根据电场方向而向上或向下移动，而集中在微胶囊中的某一面，使各微胶囊呈现出黑色或白色。Taking a prior art electronic ink layer as an example: the charged particles are positively charged and negatively charged in different colors (eg black and white) and the charged particles are contained in a microcapsule with a transparent fluid. When the electric field between each pixel electrode of the thin film transistor array substrate and the transparent electrode layer changes, the positive and negative charges of different colors will move up or down according to the direction of the electric field, thereby making each microcapsule appear black or white . In addition, microcapsules can also contain single charges and opaque fluids of different colors (eg black and white). When the electric field between each pixel electrode of the thin film transistor array substrate and the transparent electrode layer changes, the single charges in the charged particles will move up or down according to the direction of the electric field, and concentrate on one side of the microcapsules, making each microcapsule Capsules appear black or white.

以再一现有技术的电子墨水层为例，带电粒子为表面具有二种不同颜色(例如：黑色和白色)的双色带电粒子，且双色带电粒子的表面根据表面颜色，而具有不同的电荷。当薄膜晶体管阵列基板的各像素电极与透明电极层之间的电场改变时，此双色带电粒子便会根据电场方向而滚动，进而使各带电粒子呈现出黑色或白色。Taking another electronic ink layer in the prior art as an example, the charged particles are two-color charged particles with two different colors (eg, black and white) on the surface, and the surfaces of the two-color charged particles have different charges according to the surface colors. When the electric field between each pixel electrode of the thin film transistor array substrate and the transparent electrode layer changes, the two-color charged particles will roll according to the direction of the electric field, so that each charged particle appears black or white.

图1A为现有技术的一电子墨水显示面板的结构示意图，图1B为图1A中的电子墨水显示面板的薄膜晶体管阵列基板的俯视图，其中图1A的电子墨水显示面板的薄膜晶体管阵列基板是沿着图1B中的剖面线A-A’的剖面图。请同时参照图1A与图1B，电子墨水显示面板10包括一薄膜晶体管阵列基板20、一前盖板30以及一电子墨水层40。其中，前盖板30配置于薄膜晶体管阵列基板20的上方。电子墨水层40配置于前盖板30与薄膜晶体管阵列基板20之间。Fig. 1A is a schematic structural view of an electronic ink display panel in the prior art, and Fig. 1B is a top view of the thin film transistor array substrate of the electronic ink display panel in Fig. 1A, wherein the thin film transistor array substrate of the electronic ink display panel in Fig. 1A is along the Follow the sectional view of the section line AA' in Fig. 1B. Please refer to FIG. 1A and FIG. 1B at the same time. The electronicink display panel 10 includes a thin filmtransistor array substrate 20 , afront cover 30 and anelectronic ink layer 40 . Wherein, thefront cover 30 is disposed above theTFT array substrate 20 . Theelectronic ink layer 40 is disposed between thefront cover 30 and theTFT array substrate 20 .

薄膜晶体管阵列基板20包括一基板21、多条扫描线22、多条数据线23以及多个次像素单元24。其中，扫描线22、数据线23配置于基板21上，并于基板21上定义多个像素区域21a。次像素单元24分别配置基板21上的像素区域21a中，且每一次像素单元24具有一储存电容24a。此外，每一次像素单元24还具有一薄膜晶体管24b以及一像素电极24c。薄膜晶体管24b与其中一条扫描线22及其中一条数据线23电性相连。像素电极24c则与薄膜晶体管24b电性相连。前盖板30包括一保护膜32以及一透明电极层34。透明电极层34配置于保护膜32上。TheTFT array substrate 20 includes asubstrate 21 , a plurality ofscan lines 22 , a plurality ofdata lines 23 and a plurality ofsub-pixel units 24 . Wherein, thescan lines 22 and thedata lines 23 are arranged on thesubstrate 21 , and define a plurality of pixel regions 21 a on thesubstrate 21 . Thesub-pixel units 24 are respectively disposed in the pixel regions 21 a on thesubstrate 21 , and eachsub-pixel unit 24 has astorage capacitor 24 a. In addition, eachsub-pixel unit 24 also has athin film transistor 24b and apixel electrode 24c. The TFT 24b is electrically connected to one of thescan lines 22 and one of thedata lines 23 . Thepixel electrode 24c is electrically connected to thethin film transistor 24b. Thefront cover 30 includes aprotective film 32 and atransparent electrode layer 34 . Thetransparent electrode layer 34 is disposed on theprotective film 32 .

承上述，通过在扫描线22、数据线23以及透明电极层34上施加适当的电压信号，使像素电极24c充放电。如此，电子墨水材料层40中的微胶囊41的带有颜色的电荷便会被驱动，电子墨水显示装置10便可显示画面。上述的电子墨水显示装置10只能显示黑白的画面。然而，目前显示装置的彩色化已经成为必然的趋势，若电子墨水显示装置10仅能显示出黑白的画面，其应用层面将有所限制。Based on the above, by applying appropriate voltage signals to thescan line 22 , thedata line 23 and thetransparent electrode layer 34 , thepixel electrode 24 c is charged and discharged. In this way, the colored charges of themicrocapsules 41 in the electronicink material layer 40 will be driven, and the electronicink display device 10 can display images. The above-mentioned electronicink display device 10 can only display black and white images. However, the current colorization of display devices has become an inevitable trend. If the electronicink display device 10 can only display black and white images, its application level will be limited.

图1C为又一现有技术的电子墨水显示面板42的结构示意图，电子墨水显示面板42类似于电子墨水显示面板10，但不同之处为：电子墨水显示面板42的电子墨水层40使用双色带电粒子44来取代图1A所示的微胶囊41。FIG. 1C is a schematic structural view of another electronicink display panel 42 in the prior art. The electronicink display panel 42 is similar to the electronicink display panel 10, but the difference is that theelectronic ink layer 40 of the electronicink display panel 42 uses two-color electrification.Particles 44 are used instead ofmicrocapsules 41 shown in FIG. 1A.

图1D为再一现有技术的电子墨水显示面板45的结构示意图，电子墨水显示面板45类似于电子墨水显示面板10，但不同之处为：电子墨水显示面板45的电子墨水层40的微胶囊41包含不透明流体46(例如：白色)和单一带电粒子47(例如黑色)。带电粒子47可根据电场方向来上下移动，若带电粒子47往上移动，电子墨水显示面板45即显示黑色，若带电粒子47往下移动，电子墨水显示面板45则显示白色。1D is a schematic structural view of another electronicink display panel 45 in the prior art. The electronicink display panel 45 is similar to the electronicink display panel 10, but the difference is: the microcapsules of theelectronic ink layer 40 of the electronicink display panel 45 41 comprises an opaque fluid 46 (eg white) and single charged particles 47 (eg black). Thecharged particles 47 can move up and down according to the direction of the electric field. If thecharged particles 47 move upward, theE-ink display panel 45 displays black. If thecharged particles 47 move downward, theE-ink display panel 45 displays white.

Please refer to FIG. 3A and FIG. 3C at the same time. In the electronicink display panel 100, the sharedelectrode 310, one of the firstink material patterns 410 and the correspondingfirst pixel electrode 212c form afirst display capacitor 410a, whose capacitance value is Ce1 . The sharedelectrode 310 , one of the secondink material patterns 420 and the correspondingsecond pixel electrode 214c form asecond display capacitor 420a with a capacitance value of Ce2. The sharedelectrode 310 , one of the thirdink material patterns 430 and the correspondingthird pixel electrode 216 c form athird display capacitor 430 a whose capacitance is Ce3.

在本实施例中，为了使电子墨水显示面板100能显示彩色画面，故以具有不同颜色的第一墨水材料图案410、第二墨水材料图案420以及第三墨水材料图案430组成电子墨水层400。由于第一墨水材料图案410、第二墨水材料图案420、第三墨水材料图案430的材质不同，因此第一墨水材料410、第二墨水材料420以及第三墨水材料430的介电系数也会不同。如此将造成第一显示电容器410a的电容值Ce1、第二显示电容器420a的电容值Ce2以及第三显示电容器430a的电容值Ce3都不相同，即Ce1≠Ce2≠Ce3。In this embodiment, in order to enable the electronicink display panel 100 to display color images, theelectronic ink layer 400 is composed of the firstink material pattern 410 , the secondink material pattern 420 and the thirdink material pattern 430 with different colors. Since the materials of the firstink material pattern 410, the secondink material pattern 420, and the thirdink material pattern 430 are different, the dielectric coefficients of thefirst ink material 410, thesecond ink material 420, and thethird ink material 430 will also be different. . In this way, the capacitance value Ce1 of thefirst display capacitor 410a, the capacitance value Ce2 of thesecond display capacitor 420a, and the capacitance value Ce3 of thethird display capacitor 430a are all different, that is, Ce1≠Ce2≠Ce3.

此外，第一储存电容器212a的电容值为C1，第二储存电容器214a的电容值为C2，而第三储存电容器216a的电容值为C3。然而，为了使C1+Ce1＝C2+Ce2＝C3+Ce3，第一储存电容器212a所占据的面积被设计为A1，第二储存电容器214a所占据的面积被设计为A2，且第三储存电容器216a所占据的面积被设计为A3，而A1≠A2≠A3。通过将A1、A2与A3设计为具有不的值，以使C1≠C2≠C3，进而使总电容值相同。类似地，第一墨水材料图案410、第二墨水材料图案420以及第三墨水材料图案430中的微胶囊若仅包含有不同颜色的带电染料和不透明液体的微胶囊，上述的结构也可使电子墨水显示装置100达到总电容值相等的目的。In addition, the capacitance value of thefirst storage capacitor 212a is C1, the capacitance value of thesecond storage capacitor 214a is C2, and the capacitance value of thethird storage capacitor 216a is C3. However, in order to make C1+Ce1=C2+Ce2=C3+Ce3, the area occupied by thefirst storage capacitor 212a is designed to be A1, the area occupied by thesecond storage capacitor 214a is designed to be A2, and the area occupied by thethird storage capacitor 216a The occupied area is designed as A3, and A1≠A2≠A3. By designing A1, A2 and A3 to have different values so that C1≠C2≠C3, the total capacitance value is the same. Similarly, if the microcapsules in the firstink material pattern 410, the secondink material pattern 420, and the thirdink material pattern 430 only contain microcapsules of charged dyes of different colors and opaque liquids, the above structure can also make electrons Theink display device 100 achieves the purpose of equal total capacitance.

需注意的是，在本实施例中，第一储存电容器212a、第二储存电容器214a以及第三储存电容器216a虽然分别具有不同的电容值C1、C2以及C3。然而，第一储存电容器212a、第二储存电容器214a以及第三储存电容器216a并不限定必须分别具有不同的电容值。在其它的实施例中，第一储存电容器212a例如具有与第二储存电容器214a不同的电容值，第三储存电容器216a例如具有与第二储存电容器214a相同的电容值，即C1≠C2，C2＝C3。It should be noted that, in this embodiment, although thefirst storage capacitor 212a, thesecond storage capacitor 214a and thethird storage capacitor 216a have different capacitance values C1, C2 and C3 respectively. However, thefirst storage capacitor 212a, thesecond storage capacitor 214a and thethird storage capacitor 216a are not limited to have different capacitance values respectively. In other embodiments, thefirst storage capacitor 212a has, for example, a different capacitance value from thesecond storage capacitor 214a, and thethird storage capacitor 216a has, for example, the same capacitance value as thesecond storage capacitor 214a, that is, C1≠C2, C2= C3.
