技术领域technical field

本发明涉及一种显示装置,特别是涉及一种可改善显示效果的显示装置。The invention relates to a display device, in particular to a display device capable of improving display effect.

背景技术Background technique

近年来，随着科技的进步与社会的发展，显示装置于各种电子产品中的使用已越来越广泛。而且，随着电子产品轻薄短小且易于携带的发展趋势，市场上更出现了具有厚度薄且易于弯曲等优点的可挠式显示器，如微杯电泳显示器(Microcup Electrophoretic Display)、粉体移动显示器(Quick Response-Liquid Powder Display，QR-LPD)与电湿润式显示器(Electro-wetting Display，EWD)。In recent years, with the advancement of science and technology and the development of society, display devices have become more and more widely used in various electronic products. Moreover, with the development trend of electronic products being light, thin, small and easy to carry, flexible displays with advantages of thinness and easy bending have appeared on the market, such as Microcup Electrophoretic Display, powder mobile display ( Quick Response-Liquid Powder Display, QR-LPD) and Electro-wetting Display (EWD).

以微杯电泳显示器为例，其包括多个微杯显示单元，每个微杯显示单元具有溶剂以及分散在溶剂中的带电粒子。在微杯电泳显示器的驱动过程中，所施加的驱动电压除了可提供欲驱动的微杯显示单元显示影像所需的电场外，往往还会对其附近的微杯显示单元产生影响，使其中的带电粒子产生不当的运动，也就是发生所谓的串音(Cross-talk)现象。因而容易造成灰阶改变或画面失真，影响显示效果。Taking the microcup electrophoretic display as an example, it includes a plurality of microcup display units, and each microcup display unit has a solvent and charged particles dispersed in the solvent. In the driving process of the microcup electrophoretic display, the applied driving voltage can not only provide the electric field required for the microcup display unit to be driven to display images, but also often affect the nearby microcup display units, so that the Improper movement of charged particles is the so-called Cross-talk phenomenon. Therefore, it is easy to cause gray scale change or picture distortion, which affects the display effect.

为避免相邻的微杯显示单元间发生串音现象，现有习知提出的解决方法是增加相邻的微杯显示单元间的间距或提高微杯显示单元的驱动临界电压。然而，相邻的微杯显示单元间的间距愈大，微杯电泳显示器的分辨率愈低。此外，提高微杯显示单元的驱动临界电压则会降低显示装置的反应速率。In order to avoid crosstalk between adjacent microcup display units, conventional solutions are to increase the spacing between adjacent microcup display units or increase the driving threshold voltage of the microcup display units. However, the larger the distance between adjacent microcup display units, the lower the resolution of the microcup electrophoretic display. In addition, increasing the driving threshold voltage of the microcup display unit will reduce the response rate of the display device.

因此，如何在无损及分辨率及反应速率的前提下，避免显示单元间发生串音现象，从而提升显示装置的显示效果，实为相关领域的人员所重视的议题之一。Therefore, how to avoid crosstalk between the display units without compromising the resolution and response rate, so as to improve the display effect of the display device, is actually one of the issues that people in the related field pay attention to.

由此可见，上述现有的显示装置在结构与使用上，显然仍存在有不便与缺陷，而亟待加以进一步改进。为了解决上述存在的问题,相关厂商莫不费尽心思来谋求解决之道,但长久以来一直未见适用的设计被发展完成,而一般产品又没有适切结构能够解决上述问题，此显然是相关业者急欲解决的问题。因此如何能创设一种新型的显示装置,实属当前重要研发课题之一，亦成为当前业界极需改进的目标。It can be seen that the above-mentioned existing display device obviously still has inconveniences and defects in structure and use, and needs to be further improved urgently. In order to solve the above problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above problems. This is obviously the relevant industry. urgent problem to be solved. Therefore, how to create a new type of display device is one of the important research and development topics at present, and has also become a goal that the industry needs to improve.

有鉴于上述现有的显示装置存在的缺陷,本发明人基于从事此类产品设计制造多年丰富的实务经验及专业知识，并配合学理的运用,积极加以研究创新，以期创设一种新型的显示装置,能够改进一般现有的显示装置,使其更具有实用性。经过不断的研究、设计,并经过反复试作样品及改进后,终于创设出确具实用价值的本发明。In view of the defects of the above-mentioned existing display devices, the inventor actively researches and innovates based on years of rich practical experience and professional knowledge engaged in the design and manufacture of such products, and cooperates with the application of academic theories, in order to create a new type of display device , can improve the general existing display device and make it more practical.

有关本发明的前述及其他技术内容、特点及功效，在以下配合参考图式的较佳实施例的详细说明中将可清楚的呈现。为了方便说明,在以下的实施例中，相同的元件以相同的编号表示。The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the drawings. For the convenience of description, in the following embodiments, the same elements are denoted by the same numbers.

图1为本发明的一实施例中显示装置的剖面示意图。请参阅图1所示，显示装置10包括第一基板11、多个显示单元12、第二基板13以及多个间隔壁14，其中，第二基板13配设于第一基板11的上方，显示单元12配置于第一基板11与第二基板13之间，且每一显示单元12包括介电溶剂122。间隔壁14配置于相邻的显示单元12之间，且间隔壁14的材质的介电系数小于介电溶剂122的介电系数。其中，显示装置10为微杯电泳显示器，但需要指出的是，本发明并不以此为限，其还可为粉体移动显示器或电湿润式显示器。FIG. 1 is a schematic cross-sectional view of a display device according to an embodiment of the present invention. Please refer to FIG. 1, thedisplay device 10 includes afirst substrate 11, a plurality ofdisplay units 12, asecond substrate 13 and a plurality ofpartition walls 14, wherein thesecond substrate 13 is arranged above thefirst substrate 11 to display Theunits 12 are disposed between thefirst substrate 11 and thesecond substrate 13 , and eachdisplay unit 12 includes a dielectric solvent 122 . Thepartition walls 14 are disposed betweenadjacent display units 12 , and the dielectric coefficient of the material of thepartition walls 14 is smaller than that of the dielectric solvent 122 . Wherein, thedisplay device 10 is a microcup electrophoretic display, but it should be pointed out that the present invention is not limited thereto, and it can also be a powder moving display or an electrowetting display.

承上述，第一基板11可包括基底112以及配置于基底112上的驱动数组114，驱动数组114位于基底112与显示单元12之间，其中，驱动数组114可为主动式或被动式，且其例如包含薄膜晶体管数组(Thin FilmTransistor array，TFT array)与画素电极。基底112的材质可为玻璃、聚醯亚胺(Polyimide，PI)、聚对苯二甲酸乙二醇酯(PolyethyleneTerephthalate，PET)、聚萘二甲酸乙二酯(Polyethylene Naphthalene，PEN)或聚甲基丙烯酸甲酯(Polymethyl Methacrylate，PMMA)。Based on the above, thefirst substrate 11 may include abase 112 and a drivingarray 114 disposed on thebase 112, the drivingarray 114 is located between the base 112 and thedisplay unit 12, wherein the drivingarray 114 may be active or passive, and for example Contains thin film transistor array (Thin FilmTransistor array, TFT array) and pixel electrodes. The material of thesubstrate 112 can be glass, polyimide (Polyimide, PI), polyethylene terephthalate (Polyethylene Terephthalate, PET), polyethylene naphthalate (Polyethylene Naphthalene, PEN) or polymethyl Methyl acrylate (Polymethyl Methacrylate, PMMA).

第二基板13可包括透明板132以及透明电极134，透明板132配置于显示单元12上方，而透明电极134配置于显示单元12与透明板132之间。详细地，透明板132的材质可为玻璃、聚醯亚胺(PI)、聚对苯二甲酸乙二醇酯(PET)、聚萘二甲酸乙二酯(PEN)或聚甲基丙烯酸甲酯(PMMA)，而透明电极134的材质可为铟锡氧化物(Indium Tin Oxide，ITO)、铟锌氧化物(Indium Zinc Oxide，IZO)、氧化锌(Zinc Oxide，ZnO)或铟镓锌氧化物(Indium GalliumZinc Oxide，IGZO)。Thesecond substrate 13 may include atransparent plate 132 and atransparent electrode 134 , thetransparent plate 132 is disposed above thedisplay unit 12 , and thetransparent electrode 134 is disposed between thedisplay unit 12 and thetransparent plate 132 . In detail, the material of thetransparent plate 132 can be glass, polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN) or polymethyl methacrylate (PMMA), and the material of thetransparent electrode 134 can be indium tin oxide (Indium Tin Oxide, ITO), indium zinc oxide (Indium Zinc Oxide, IZO), zinc oxide (Zinc Oxide, ZnO) or indium gallium zinc oxide (Indium Gallium Zinc Oxide, IGZO).

显示单元12位于驱动数组114与透明电极134之间，且每个显示单元12包括多个分散于介电溶剂122中的带电粒子124。当施加电压至驱动数组114与透明电极134以驱动显示单元12时，带电粒子124会根据其电性而朝向驱动数组114或透明电极134移动，以控制通过显示单元12的光线亮度。Thedisplay unit 12 is located between the drivingarray 114 and thetransparent electrode 134 , and eachdisplay unit 12 includes a plurality of chargedparticles 124 dispersed in a dielectric solvent 122 . When voltage is applied to the drivingarray 114 and thetransparent electrode 134 to drive thedisplay unit 12 , the chargedparticles 124 will move toward the drivingarray 114 or thetransparent electrode 134 according to their electric properties, so as to control the brightness of the light passing through thedisplay unit 12 .

间隔壁14用以隔开相邻的显示单元12，且其介电系数小于介电溶剂122的介电系数。由于电容值与电场所在之处的介质的介电系数成反比，因此如图2所示，当施加电压至驱动数组114与透明电极134以驱动右边的显示单元12时，其于间隔壁14所产生的电容值较习知小，因而可避免在中央未被驱动的显示单元12内发生串音现象，从而在不损及显示装置10的分辨率及反应速率的前提下改善其显示效果。详细来说，间隔壁14的材质可为固体,例如是含氟材料、多孔材料或高分子材料。特别地,为使间隔壁14具有更佳的屏蔽效果，间隔壁14的材质的介电系数小于介电溶剂122的介电系数的二分之一。举例来说，间隔壁14的材质的介电系数小于4。Thepartition walls 14 are used to separateadjacent display units 12 , and have a dielectric coefficient smaller than that of the dielectric solvent 122 . Since the capacitance value is inversely proportional to the dielectric coefficient of the medium where the electric field is located, as shown in FIG. The resulting capacitance is smaller than conventional ones, so that crosstalk in the centralundriven display unit 12 can be avoided, thereby improving the display effect without compromising the resolution and response speed of thedisplay device 10 . In detail, the material of thepartition wall 14 can be solid, such as fluorine-containing material, porous material or polymer material. In particular, in order to make thepartition wall 14 have a better shielding effect, the dielectric constant of the material of thepartition wall 14 is less than half of that of the dielectric solvent 122 . For example, the dielectric coefficient of the material of thepartition walls 14 is less than 4.

此外，请再次参照图1所示，熟习此技艺者应该知道，显示装置10在第一基板11与第二基板13还可包括密封胶15，形成于多个显示单元12的外围，用于将这些显示单元12密封于第一基板11与第二基板13之间。此外，如图3所示，为使显示装置10具有彩色显示效果，第二基板13更可包括彩色滤光膜136，配置于透明板132与透明电极136之间。In addition, please refer to FIG. 1 again. Those skilled in the art should know that thedisplay device 10 may further include asealant 15 on thefirst substrate 11 and thesecond substrate 13, which is formed on the periphery of a plurality ofdisplay units 12 for sealing Thedisplay units 12 are sealed between thefirst substrate 11 and thesecond substrate 13 . In addition, as shown in FIG. 3 , in order to make thedisplay device 10 have a color display effect, thesecond substrate 13 may further include acolor filter film 136 disposed between thetransparent plate 132 and thetransparent electrode 136 .

综上所述，本发明的显示装置的间隔壁的介电系数小于介电溶剂的介电系数，因此可在驱动选定的显示单元时，降低驱动电压在间隔壁所产生的电容值,进而避免在未被驱动的显示单元内发生串音现象。由此可知,本发明可在无损及显示装置的分辨率与反应速率的前提下，提升显示效果。In summary, the dielectric coefficient of the partition wall of the display device of the present invention is smaller than the dielectric coefficient of the dielectric solvent, so when the selected display unit is driven, the capacitance value generated by the driving voltage at the partition wall can be reduced, and then Avoid crosstalk in undriven display units. It can be seen that the present invention can improve the display effect without compromising the resolution and response rate of the display device.
