技术领域 FIELD

[0001] 本实用新型属于立体(3D)图像显示技术领域,尤其涉及一种集成3D光栅和电容触摸屏的装置、以及包括该触摸屏的显示装置。 [0001] The present invention belongs to a stereoscopic (3D) image display technology, and particularly relates to an apparatus and a 3D grating integrated capacitive touch screen, and a display device including a touch screen.

背景技术 Background technique

[0002] 立体(3D)图像显示装置基本可以分为两大类:眼镜型立体图像显示装置和无眼镜型(裸眼)立体图像显示装置(自动立体图像显示装置)。 [0002] The stereoscopic (3D) image display apparatus can be basically divided into two categories: glasses type stereoscopic image display apparatus and a non-glasses type (naked eye) stereoscopic image display apparatus (image display apparatus autostereoscopic). 其中眼镜型立体图像显示装置中使用了偏振眼镜、快门眼镜和红蓝眼镜等,眼镜的存在会导致观看者感觉不方便并可能会引起眼科疾病。 Wherein the glasses type stereoscopic image display apparatus using the polarized glasses, shutter glasses, and red and blue glasses, the glasses may lead to the presence of the viewer feel inconvenient and may cause eye disease. 而无眼镜型立体图像显示装置仅仅通过直接观看屏幕就能够欣赏立体图像,因此,当前正对无眼镜型立体图像显示装置进行深入研究。 Without glasses type stereoscopic image display device only by direct viewing screen will be able to enjoy three-dimensional image, therefore, currently being glasses-free stereoscopic image display device in-depth study.

[0003] 无眼镜型立体图像显示装置的立体图像显示方法包括有透镜方法、全息方法以及视差栅栏方法等。 [0003] The non-glasses type stereoscopic image display method for a stereoscopic image display apparatus includes a lenticular method, a parallax barrier method and a holographic method has. 其中透镜法和视差栅栏法是通过3D光栅来实现3D显示的,其中透镜法中可以使用柱状透镜光栅,视差栅栏法中可以使用视差栅栏(也称为视差屏障栅栏),柱状透镜光栅和视差栅栏这两种3D光栅在3D显示中的应用,各具有相应的技术优点,因此,分别在其相适用的领域中应用。 Wherein the lens and a parallax barrier method is a method achieved by the raster 3D 3D display method may be used wherein the lens raster lenticular lens, a parallax barrier method, a parallax barrier can be used (also referred to as a parallax barrier barrier), a parallax barrier and lenticular lens grating application of the two gratings 3D 3D display, each having a respective technical advantages, therefore, are suitable for application in the areas of its phase.

[0004] 同时注意到,柱状透镜光栅和视差栅栏头可以通过液晶盒形成,即分别形成液晶柱状透镜光栅和液晶视差栅栏。 [0004] Also note that the raster lenticular lens and a parallax barrier may be formed by the first liquid crystal cell, i.e. the liquid crystal are formed lenticular lens grating and the liquid crystal parallax barrier. 图1所示为常规的使用3D光栅的立体图像显示装置的简单结构示意图。 FIG simple structure shown in FIG 1 a schematic view of a display device as a stereoscopic image using a conventional 3D grating. 立体图像显示装置包括二维图像显示模块10和3D光栅20,背光从二维图像显示模块10进入,经过3D光栅20后进入观察者的眼睛。 The stereoscopic image display apparatus includes a two-dimensional image display module 10 and the 3D grating 20, the backlight 10 enters the display module, 3D grating 20 after entering the eyes of the viewer from a two dimensional image. 3D光栅20中,其可以为液晶柱状透镜光栅和液晶视差栅栏。 3D grating 20, which may be a liquid crystal barrier liquid crystal parallax barriers and lenticular lens. 其中,液晶视差栅栏是通过液晶的扭转实现对来自二维图像显示模块10的光的遮挡的;液晶柱状透镜光栅利用液晶的双折射特性,一种方法是在需要形成一个液晶透镜的相应位置设置多个电极,当对这些电极加不同的控制电压时,该位置的液晶在光学特性上形成类似于实体柱状透镜的汇聚效果(参见美国专利号为US5493427的专利技术)。 Wherein the liquid crystal parallax barrier is to achieve a two-dimensional image display from the blocking of the light by the liquid crystal module 10 is twisted; corresponding position of a liquid crystal lenticular lens grating using birefringence of the liquid crystal, a method is required to form a liquid crystal lens a plurality of electrodes, these electrodes when different voltages applied, the liquid crystal is similar to the position of the entity formed lenticular lens converging effect on the optical properties (see U.S. Pat. No. US5493427 patented technology). 在图1所示实例中,3D光栅20包括由下向上依次设置的下偏光片210、下透明电极层220、液晶(LC)层230、上透明电极层240以及上偏光片250。 In the example shown in FIG. 1, 3D grating 20 includes a lower polarizer are sequentially arranged from bottom to top 210, lower transparent electrode layer 220, a liquid crystal (LC) layer 230, a transparent electrode layer 240 and the upper polarizer 250. 通常地,下透明电极层220、上透明电极层240是由ITO (Indium Tin Oxide,铟锡金属氧化物)导电玻璃层,下透明电极层220和上透明电极层240上在相向于液晶层230的表面分别形成有一定图案的ITO电极(例如,如图1所示的用于形成视差栅栏的ITO电极图案),通过对ITO电极的控制可以控制液晶形成视差栅栏或液晶柱状透镜光栅。 Generally, the lower transparent electrode layer 220, 240 on the transparent electrode layer 230 by the ITO (Indium Tin Oxide, indium tin metal oxide) conductive glass layer, a lower transparent electrode layer 220 and the upper transparent electrode layer facing the liquid crystal layer 240 the surface of the ITO electrode are formed with a certain pattern (e.g., as shown in FIG. 1 for an ITO electrode pattern parallax barrier), the ITO electrode by controlling the liquid crystal can be formed a liquid crystal parallax barrier or lenticular lens grating.

[0005] 同时注意到,触摸屏在各种个人移动显示装置中广泛应用。 [0005] Also note, the touch screen apparatus is widely used in a variety of personal mobile display. 触摸屏中,按照工作原理,主要可以分为电阻式触摸屏和电容触摸屏。 Touch screen, according to the working principle, it can be divided into resistive touch screens and capacitive touch screens. 进一步电容触摸屏主要包括自电容触摸屏(self-capacitive touch panel)和互电容角虫摸屏(mutual capacitive touch panel)。 Further including capacitive touch screen capacitance touch screen (self-capacitive touch panel) and a mutual capacitance touch screen angle worm (mutual capacitive touch panel).

[0006]自电容触摸屏中,在其透明电极基板(玻璃基板或聚酯材料(例如,PET (ethyleneterephthalate,聚对苯二甲酸乙二酯))基板)的表面,采用ITO(Indium Tin Oxide,铟锡金属氧化物)等透明导电材料制作成横向与纵向电极阵列,这些横向和纵向的电极可以用来形成电容,该电容即通常所说的自电容,也就是电极对地的电容。 [0006] In a self capacitance touch screen, in which a transparent electrode substrate (a glass substrate or a polyester material (e.g., PET (ethyleneterephthalate, polyethylene terephthalate)) substrate) surface using ITO (Indium Tin Oxide, Indium metal tin oxide) transparent conductive material of the electrode array transverse and longitudinal, transverse and vertical electrodes may be used to form a capacitance known as the self-capacitance, i.e. the capacitance to ground electrodes. 当手指触摸到电容屏时,手指的电容将会叠加到自电容上,使触摸屏电容量增加。 When a finger touches the capacitive screen, capacitive finger will be superimposed on the self-capacitance, the touch screen capacity increase. 自电容触摸屏的控制电路通过测量容性负载的变化来检测触摸位置。 Since the control circuit of a capacitive touch screen touch position is detected by measuring the change of the capacitive load.

[0007] 互电容屏中,在其透明电极基板的表面,采用IT0(Indium Tin Oxide,铟锡金属氧化物)等透明导电材料制作成横向与纵向电极阵列;它与自电容屏的区别在于,纵向电极与横向电极相交叉的地方将会形成互电容,也即纵向电极与相应的横向电极分别构成了电容的两极。 [0007] The mutual capacitance screen, the surface of the transparent electrode substrate, a transparent conductive material IT0 (Indium Tin Oxide, indium tin metal oxide) produced transversely to the longitudinal array of electrodes; and distinguish it from that capacitive screen, local longitudinal electrodes and lateral electrodes crossing will form a mutual capacitance, i.e. with the respective lateral longitudinal electrodes constituting the capacitance electrodes are bipolar. 当手指触摸到电容屏时,影响了触摸点附近两个电极之间的耦合,从而改变了这两个电极之间的电容量。 Capacitance when a finger touches the screen, the influence of coupling between the two touch points near the electrodes, thereby changing the capacitance between these two electrodes. 检测互电容大小时,在一实例中,横向的电极依次发出激励信号,纵向的所有电极同时接收信号,这样可以得到所有横向和纵向电极交汇点的电容值大小,即得到整个触摸屏的二维平面的电容大小。 Detecting the mutual size of the capacitor, in one example, the lateral electrode sequentially emits excitation signal, all the electrodes longitudinal receive signals simultaneously, which can give a capacitance value of the sizes of all horizontal and vertical electrode intersection, i.e. to give the entire touch screen a two-dimensional plane the size of the capacitor. 根据触摸屏范围内二维平面的电容量数据的变化,可以计算出每一个触摸点的坐标。 The changes in the capacity range of the touch screen of the two-dimensional plane data, can calculate the coordinates of each touch point.

[0008] 然而,当3D光栅20应用于带有电容式触摸屏的个人移动显示装置时,例如,触摸屏手机等,如果直接在触摸屏上覆盖3D光栅20以达到立体图像显示效果,那么由于3D光栅20的存在将导致触摸屏的触摸输入信息的功能失效。 [0008] However, when the 3D grating 20 is applied to a personal mobile with a capacitive touch screen display device, e.g., a touch screen phone, etc., if the cover 3D grating 20 directly on the touch screen in order to achieve stereoscopic image display effect, then since the 3D grating 20 the presence of touch screen function will lead to the failure of input information.

[0009] 有鉴于此,针对同时要求具有触摸输入功能和立体图像显示功能的要求,尤其对电容触摸屏,有必要对对电容触摸屏和3D光栅集成整合。 [0009] In view of this, for the same time required to have a touch input function and a stereoscopic image display function requirements, especially for the capacitive touch screen, it is necessary to integrate the integration of the capacitive touch screen and 3D raster.

具体实施方式 Detailed ways

[0030] 下面介绍的是本实用新型的多个可能实施例中的一些,旨在提供对本实用新型的基本了解,并不旨在确认本实用新型的关键或决定性的要素或限定所要保护的范围。 [0030] The following describes the present invention is a plurality of possible embodiments of the some embodiments, the present invention aims to provide a basic understanding of, and are not intended to confirm the scope of the present invention a key or critical elements or limitations to be protected . 容易理解,根据本实用新型的技术方案,在不变更本实用新型的实质精神下,本领域的一般技术人员可以提出可相互替换的其他实现方式。 Easy to understand, according to the present invention the technical solution, without changing the essence of the spirit of the present invention, the ordinary skill in the art can make other implementations can be replaced each other. 因此,以下具体实施方式以及附图仅是对本实用新型的技术方案的示例性说明,而不应当视为本实用新型的全部或者视为对本实用新型技术方案的限定或限制。 Accordingly, the following detailed description and drawings are merely illustrative of the technical solution of the present invention and should not be considered novel or all be considered as limiting the present invention to limit the present invention or technical solutions.

[0031] 在图中,为了清楚放大了层和区域的厚度,但作为示意图不应该被认为严格反映了几何尺寸的比例关系。 [0031] In the drawings, the thicknesses of layers are exaggerated for clarity and regions, but should not be considered as a schematic strictly proportional relationship reflects the geometry.

[0032] 在图中,为了突出本实用新型的主要层,没有包含一些次要的层,比如层与层之间用于粘贴的OCA (Optically Clear Adhesive,光学透明胶)层。 [0032] In the drawings, the present invention in order to highlight the main layer, there are some minor layer comprising, for example, paste OCA (Optically Clear Adhesive, optically clear adhesive) layer between the layers.

[0033] 在本实用新型中,以二维图像显示模块的显示平面定义为Xy平面,Z坐标垂直于xy平面,从二维图像显示模块至观察者的方向(一般为二维图像显示模块射出光线至观察者的双眼的方向)定义为z坐标正方向,其中,本实用新型中所提到的上、下等方位用语是相对于附图中所示意的z坐标来定义的。 [0033] In the present invention, the two-dimensional image display plane is defined as Xy flat display module, Z coordinate perpendicular to the xy plane, the direction of the observer to the display module from the two-dimensional image (two-dimensional image display module typically emitted direction of light to the eyes of the observer) is defined as a positive direction of z-coordinate, orientation terms wherein the present invention is mentioned, the drawings and the like are defined as illustrated with respect to the z-coordinate. 但是,它们是相对的概念,其可以根据显示装置的使用放置方位不同、观察者的方位变化而相应地变化。 However, they are relative concepts, which can be placed according to different orientations using the display device, the change in orientation of the observer changes accordingly.

[0034] 图2所示为按照本实用新型一实施例的集成装置30应用于二维图像显示模块时的截面结构示意图。 [0034] FIG. 2 is a schematic cross-sectional structure when applied to the two-dimensional image display module according to the integrated device 30 according to an embodiment of the invention. 在该实施例中,该集成装置为集成3D光栅和自电容触摸屏的装置30,将该装置30贴合于二维图像显示模块100时,整体可以形成具有触摸屏功能的立体图像显示装置。 In this embodiment, the integrated device and an integrated 3D grating device 30 from the capacitive touch screen, the device 30 is bonded to the two-dimensional image display module 100, a stereoscopic image may be formed integrally with the touch panel function of the display device.

[0035] 继续参阅图2,集成3D光栅和自电容触摸屏的装置包括由下至上(即图中的z轴的正方向)依次堆叠的第一ITO导电玻璃层310、液晶层320、第二ITO导电玻璃层330以及偏光片层390。 [0035] With continued reference to FIG. 2, the integration means comprises a 3D grating and a self-capacitance touch screen from the bottom (i.e., the positive direction of the z-axis of the figure) of a first conductive ITO glass layer 310 are sequentially stacked, the liquid crystal layer 320, a second ITO conductive glass layer 330 and the polarizer layer 390. 其中,第一ITO导电玻璃层310和/或第二ITO导电玻璃层330具有绝缘特性,第一ITO导电玻璃层310、液晶层320、第二ITO导电玻璃层330可以形成3D光栅的主要部分(也即液晶盒),同时,在该实施例中,第二ITO导电玻璃层330还可以用于形成电容触摸屏的主要部分。 Wherein the first conductive glass ITO layer 310 and / or the second ITO glass layer 330 having insulation properties, a first conductive ITO glass layer 310, a liquid crystal layer 320, a second ITO glass layer 330 may be formed of a main portion of the 3D grating ( i.e. the liquid crystal cell), while, in this embodiment, a second ITO conductive glass layer 330 may also be used to form the main part of the capacitive touch screen. 需要说明的是,以上各层之间可能还设置有其它特殊功能层,例如,各层之间的用于粘接的透明的胶层或结构固件,但是这不构成对本实用新型的限制。 Incidentally, it may also be provided between other layers above a particular functional layer, e.g., a transparent adhesive layer or firmware structure for bonding between the layers, but this does not constitute a limitation of the present novel practical pair.

[0036] 具体地,在第一ITO导电玻璃层310相向于液晶层320的一面上,构图形成ITO电极311,ITO电极311用作液晶层320的下电极。 [0036] Specifically, the first conductive glass ITO layer 310 facing the liquid crystal layer 320 on one surface of the patterned ITO electrode 311 is formed, an ITO electrode as the lower electrode 311 of the liquid crystal layer 320. 同样,在第二ITO导电玻璃层330相向于液晶层320的一面上,构图形成ITO电极331,ITO电极331用作液晶层320的上电极。 Also in the second ITO glass layer 330 on the opposite side of the liquid crystal layer 320, and patterning the ITO electrode 331, ITO electrode 331 serves as the upper electrode of the liquid crystal layer 320. ITO电极311、液晶层320、IT0电极331之间的具体设置等为本领域技术人员所了解,在此不再具体描述。 ITO electrodes 311, the liquid crystal layer 320 disposed between the concrete and the like IT0 electrode 331 understood by the skilled person and will not be described in detail. 应当理解的是,本领域技术人员可以相应设置ITO电极311和/或ITO电极331的形状,来使该液晶盒可以用来形成液晶视差栅栏或液晶柱状透镜光栅,例如,美国专利号为US5493427、名称为“Three-Dimensional Display Unit With a Variable Lens”的专利中公开了设置ITO电极以及相应部件来形成或控制液晶柱状透镜光栅的方式。 It should be appreciated that those skilled in the art can form an ITO electrode 331 corresponding to 311 and / or the ITO electrodes to the liquid crystal cell so that the liquid crystal may be used to form a liquid crystal parallax barrier or lenticular lens grating, e.g., U.S. Patent No. US5493427, entitled "Three-Dimensional Display Unit With a Variable lens", discloses an ITO electrode and a respective control member or to form a liquid crystal lenticular lens raster manner.

[0037] 以形成3D光栅中的液晶视差栅栏为例,直线偏振光(偏光片层390所产生)垂直射入液晶层后,其偏光方向会被液晶扭转90度,因此,第一ITO导电玻璃层310、液晶层320和第二ITO导电玻璃层336所组成的液晶盒在平行偏振片方向可以遮光,从而可以显示栅栏。 [0037] In a liquid crystal parallax barrier 3D grating for example, linearly polarized light (polarized light generating sheet 390) incident on the liquid crystal layer is perpendicular to its polarization direction is twisted 90 ° by the liquid crystal, therefore, a first ITO glass layer 310, the liquid crystal cell and a liquid crystal layer 320, a second ITO glass layer 336 may be composed of a light-shielding direction parallel polarizer, the fence can be displayed.

[0038] 进一步,具体地,在同一层导电玻璃层上,即在第二ITO导电玻璃层330上、背向于液晶层320的一面上(即相向于偏光片层390的一面上),构图形成有ITO电极341。 [0038] Further, in particular, on the same layer of conductive glass layer, i.e. on the second conductive glass ITO layer 330 facing away from one side of the liquid crystal layer 320 (i.e. facing layer on one side of the polarizer 390), patterning ITO electrode 341 is formed. ITO电极341用于形成电容触摸屏的电极层,ITO电极341的具体结构和图案设置,根据具体实现原理和具体需要,进行相应具体设计,例如,ITO电极341可以用来形成自电容触摸屏,也可以用来形成互电容触摸屏。 ITO electrode 341 for forming an electrode layer capacitive touch panel, ITO electrodes concrete structure and the pattern set 341, depending on the particular principle and particular needs, the corresponding specific design, e.g., ITO electrodes 341 can be used to form a self-capacitance touch screen, may be to form a mutual capacitance touch screen.
