Description

液晶光栅、 其制备方法以及 3D显示器 技术领域  Liquid crystal grating, preparation method thereof and 3D display
本发明的实施例涉及一种液晶光栅、 其制备方法以及 3D显示器。 背景技术  Embodiments of the present invention relate to a liquid crystal grating, a method of fabricating the same, and a 3D display. Background technique
目前， 三维显示技术已经备受关注。 三维显示技术可以使得画面变得立 体逼真， 其最基本的原理是： 观察者的左右眼分别接收不同的画面， 然后大 脑经过对图像信息进行叠加重生， 构成具有立体效果的影像。  At present, three-dimensional display technology has received much attention. The three-dimensional display technology can make the picture realistic and realistic. The basic principle is: The observer's left and right eyes respectively receive different pictures, and then the brain re-grows the image information to form a stereoscopic image.
为了实现三维显示， 现有技术是在显示屏上增加一层液晶光栅， 如图 1 所示， 液晶光栅一般是由上偏光片、 下偏光片、 上基板、 下基板、 以及在两 个基板之间的液晶层组成， 上基板和下基板分别具有条状电极和面电极， 其 工作原理示例如下：  In order to realize three-dimensional display, the prior art adds a liquid crystal grating to the display screen. As shown in FIG. 1, the liquid crystal grating is generally composed of an upper polarizer, a lower polarizer, an upper substrate, a lower substrate, and two substrates. The liquid crystal layer is composed of the upper substrate and the lower substrate respectively having a strip electrode and a surface electrode, and the working principle thereof is as follows:
当液晶光栅通电时， 与条状电极对应的液晶分子发生偏转而平行， 其他 液晶分子保持原来形状， 不发生偏转。 此时， 光线从下偏光片进入， 与下偏 光片的吸收轴平行的偏振光进入到液晶层， 偏振光通过没有发生偏转的液晶 时会逐步改变振动方向， 到达上偏振片时偏振光的振动方向刚好和上偏振片 的吸收轴平行， 则光线通过； 而偏振光通过发生偏转而平行的液晶时不会改 变振动方向， 到达上偏振片时偏振光的振动方向和上偏振片的吸收轴垂直， 这样就形成了垂直于条状电极方向的屏障栅栏， 实现了三维光栅显示模式。 在此模式下， 应该由左眼看到的图像显示在液晶屏上时， 不透明的条紋会遮 挡右眼， 同理应该由右眼看到的图像显示在液晶屏上时， 不透明的条紋会遮 挡左眼， 通过将左右眼的可视画面分开， 实现三维显示效果。  When the liquid crystal grating is energized, the liquid crystal molecules corresponding to the strip electrodes are deflected and parallel, and the other liquid crystal molecules maintain their original shape without deflection. At this time, the light enters from the lower polarizer, and the polarized light parallel to the absorption axis of the lower polarizer enters the liquid crystal layer, and the polarized light gradually changes the vibration direction when passing through the liquid crystal without deflection, and the polarized light vibrates when reaching the upper polarizing plate. The direction is just parallel to the absorption axis of the upper polarizing plate, and the light passes through; and the polarized light does not change the direction of vibration when the parallel liquid crystal is deflected, and the direction of vibration of the polarized light and the absorption axis of the upper polarizing plate are perpendicular to the upper polarizing plate. Thus, a barrier barrier perpendicular to the direction of the strip electrodes is formed, realizing a three-dimensional raster display mode. In this mode, when the image that should be seen by the left eye is displayed on the LCD screen, the opaque stripes will block the right eye. Similarly, when the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block. The left eye achieves a three-dimensional display effect by separating the visible images of the left and right eyes.

The technical solutions of the embodiments of the present invention are clearly and completely described in the accompanying drawings. It is apparent that the described embodiments are part of the embodiments of the invention, rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the described embodiments of the present invention without departing from the scope of the invention are within the scope of the invention.
下面结合附图， 对本发明实施例提供的液晶光栅、 其制备方法、 3D显示 器件及 3D显示装置的具体实施方式进行详细地说明。  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of a liquid crystal grating, a method for fabricating the same, a 3D display device, and a 3D display device according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.
本发明实施例提供的一种液晶光栅， 如图 2所示， 包括： 第一基板 101 ; 第二基板 102; 密封连接第一基板 101和第二基板 102边缘的胶框 103;位于 由第一基板 101、第二基板 102和胶框 103围成的空间中的液晶 104; 多个第 一方向条状电极 105,延伸在第一方向上且形成在第一基板 101面向液晶 104 的一面； 多个第二方向条状电极 106, 延伸在第二方向上且形成在第一方向 条状电极 105之上且与其绝缘； 面电极 107, 形成在第二基板 102面向液晶 104的一面。  The liquid crystal grating provided by the embodiment of the present invention, as shown in FIG. 2, includes: a first substrate 101; a second substrate 102; a plastic frame 103 sealingly connecting the edges of the first substrate 101 and the second substrate 102; The liquid crystal 104 in the space surrounded by the substrate 101, the second substrate 102 and the plastic frame 103; the plurality of first direction strip electrodes 105 extending in the first direction and formed on the side of the first substrate 101 facing the liquid crystal 104; The second direction strip electrodes 106 extend in the second direction and are formed on and insulated from the first direction strip electrodes 105; and the surface electrodes 107 are formed on the side of the second substrate 102 facing the liquid crystals 104.
其中， 示例性地， 可以使用透明导电层材料， 例如， ITO ( Indium Tin Oxides, 铟锡金属氧化物）作为第一方向条状电极 105、 第二方向条状电极 106和面电极 107。  Here, exemplarily, a transparent conductive layer material such as ITO (Indium Tin Oxides) may be used as the first direction strip electrode 105, the second direction strip electrode 106, and the surface electrode 107.
其中， 在具体实施时， 可以在第一方向条状电极和第二方向条状电极之 间设置绝缘材料层 108, 以实现两层条状电极相互绝缘。  Wherein, in a specific implementation, an insulating material layer 108 may be disposed between the first direction strip electrode and the second direction strip electrode to achieve insulation between the two strip electrodes.
备选地， 在第一基板 101背向液晶 104的一面该液晶光栅还具有第一偏 光片 109, 在第二基板 102背向液晶 104的一面该液晶光栅还具有第二偏光 片 110, 第一偏光片 109和第二偏光片 110能够对经过的光线进行过滤， 形 成偏振光。  Alternatively, the liquid crystal grating further has a first polarizer 109 on a side of the first substrate 101 facing away from the liquid crystal 104. The liquid crystal grating further has a second polarizer 110 on a side of the second substrate 102 facing away from the liquid crystal 104. The polarizer 109 and the second polarizer 110 are capable of filtering the passing light to form polarized light.
备选地， 在第二方向条状电极 106面向液晶 104的一面还可以设置第一 取向膜（图 2中未示出） ， 在面电极 107面向液晶 104的一面还可以设置第 二取向膜（图 2中未示出） 。 第一取向膜和第二取向膜的作用和现有液晶取 向膜的作用相同， 在此不再赘述。  Alternatively, a first alignment film (not shown in FIG. 2) may be disposed on a side of the second direction strip electrode 106 facing the liquid crystal 104, and a second alignment film may be disposed on a side of the surface electrode 107 facing the liquid crystal 104 ( Not shown in Figure 2). The roles of the first alignment film and the second alignment film are the same as those of the conventional liquid crystal alignment film, and will not be described herein.
备选地， 本发明实施例提供的上述液晶光栅的屏幕大小一般与配套使用 的显示屏的屏幕大小相一致， 当液晶光栅的屏幕较大时， 为了增强其抗压能 力，还可以在第一基板 101和第二基板 102之间设置有多个透明的支撑体（图 2中未示出） ， 以增强其抗压性。 备选地， 第一方向条状电极 105中相邻电极之间的间距与第二方向条状 电极 106中相邻电极之间的间距相同， 这样能够保证第一方向条状电极和第 二方向条状电极具有相同的透光性。 但是， 第一方向条状电极 105中相邻电 要而设置的不等， 本发明对此不做限制。 而且， 备选地， 可以根据液晶光栅 所需的分辨率和屏幕的长宽比， 具体设置第一方向条状电极 105的数量和第 二方向条状电极 106的数量。 Alternatively, the screen size of the liquid crystal grating provided by the embodiment of the present invention is generally consistent with the screen size of the display screen used for matching. When the screen of the liquid crystal grating is large, in order to enhance the pressure resistance capability, the first A plurality of transparent supports (not shown in FIG. 2) are disposed between the substrate 101 and the second substrate 102 to enhance the pressure resistance thereof. Alternatively, the spacing between adjacent ones of the first direction strip electrodes 105 is the same as the spacing between adjacent ones of the second direction strip electrodes 106, so that the first direction strip electrodes and the second direction can be ensured. The strip electrodes have the same light transmittance. However, the first direction strip electrodes 105 are unequally disposed adjacent to each other, and the present invention is not limited thereto. Moreover, alternatively, the number of the first direction strip electrodes 105 and the number of the second direction strip electrodes 106 may be specifically set according to the resolution required for the liquid crystal grating and the aspect ratio of the screen.
而且， 多个第一方向条状电极 105的宽度彼此相等， 多个第二方向条状 电极 106的宽度彼此相等。 第一方向条状电极 105和第二方向条状电极 106 的宽度可以彼此相等或不等， 本发明对此不做限制，视具体情况而定。 而且， 第一条状电极 105的宽度和第二条状电极 106的宽度均大于 5μπι。  Moreover, the widths of the plurality of first-direction strip electrodes 105 are equal to each other, and the widths of the plurality of second-direction strip electrodes 106 are equal to each other. The widths of the first direction strip electrodes 105 and the second direction strip electrodes 106 may be equal or unequal to each other, and the present invention is not limited thereto, as the case may be. Moreover, the width of the first strip electrode 105 and the width of the second strip electrode 106 are both greater than 5 μm.
本发明实施例提供的上述液晶光栅中， 如图 3所示的结构分解图， 第一 方向条状电极 105与第二方向条状电极 106中的条状电极相互不平行， 较佳 地， 第一方向条状电极 105与第二方向条状电极 106可以形成异面垂直的关 系， 并且， 本发明实施例中并不具体限定第一方向条状电极和第二方向条状 电极的条状电极方向， 可以分别为横向和纵向， 也可以为其他方向， 只要二 者方向不同即可。  In the liquid crystal grating provided by the embodiment of the present invention, as shown in the exploded view of FIG. 3, the strip electrodes in the first direction strip electrode 105 and the second direction strip electrode 106 are not parallel to each other, preferably, The one-direction strip electrode 105 and the second-direction strip electrode 106 may be in a perpendicular relationship, and the strip electrodes in the first direction strip electrode and the second direction strip electrode are not specifically limited in the embodiment of the present invention. The direction can be horizontal and vertical, or other directions, as long as the directions are different.
示例性地， 如图 3所示， 可以通过在第一基板 (图 3中未示出）上设置 与第一方向条状电极 105相连的第一电信号输入输出端 111 , 以及与第二方 向条状电极 106相连的第二电信号输入输出端 112, 用以分别对第一方向条 状电极 105和第二方向条状电极 106传递电压信号。  Illustratively, as shown in FIG. 3, the first electrical signal input/output terminal 111 connected to the first direction strip electrode 105 may be disposed on the first substrate (not shown in FIG. 3), and the second direction The second electrical signal input and output ends 112 connected to the strip electrodes 106 are used to respectively transmit voltage signals to the first direction strip electrodes 105 and the second direction strip electrodes 106.
其中， 第一电信号输入输出端 111和第二电信号输入输出端 112可以为 金属接线柱 PIN或其他常用金属线端口， 在此不做限定。  The first electrical signal input and output end 111 and the second electrical signal input and output end 112 may be metal terminal PIN or other common metal line ports, which are not limited herein.
这样，通过第一电信号输入输出端 111对第一方向条状电极 105通电后， 或者， 通过第二电信号输入输出端 112对第二方向条状电极 106通电后， 都 能与面电极 107形成电场， 使得与其对应的液晶 （图 3中未示出）偏转， 从 而在与第一方向垂直的方向或在与第二方向垂直的方向形成屏障栅栏， 可以 实现双方向的三维光栅显示模式。 其中， 具体如何实现三维显示的原理属于 现有技术， 在此不再赘述。  In this way, after the first electric strip input/output terminal 111 energizes the first direction strip electrode 105, or after the second electric signal input/output end 112 energizes the second direction strip electrode 106, both the surface electrode 107 and the surface electrode 107 can be used. The electric field is formed such that the liquid crystal (not shown in FIG. 3) corresponding thereto is deflected, thereby forming a barrier barrier in a direction perpendicular to the first direction or a direction perpendicular to the second direction, and a two-dimensional three-dimensional raster display mode can be realized. The specific principle of how to implement the three-dimensional display belongs to the prior art, and details are not described herein again.
在具体实施时， 如图 3所示， 可以将第一电信号输入输出端 111和第二 电信号输入输出端 112与第二方向条状电极 106设置在同一层上， 这样， 通 过在绝缘材料层 108上对应于第一电信号输入输出端 111的位置预留的第一 过孔 113 , 第一电信号输入输出端 111就可以通过第一过孔 113与第一方向 条状电极 105连接， 而第二电信号输入输出端 112直接和第二方向条状电极 106相连。 In a specific implementation, as shown in FIG. 3, the first electrical signal can be input to the output terminal 111 and the second The electrical signal input/output terminal 112 and the second direction strip electrode 106 are disposed on the same layer, such that the first via hole 113 reserved on the insulating material layer 108 corresponding to the position of the first electrical signal input/output terminal 111, The first electrical signal input/output terminal 111 can be connected to the first direction strip electrode 105 through the first via 113, and the second electrical signal input/output terminal 112 is directly connected to the second direction strip electrode 106.
或者， 将第一电信号输入输出端和第二电信号输入输出端与第一方向条 状电极设置在同一层上， 通过在绝缘材料层上对应于第二电信号输入输出端 的位置预留的第二过孔， 第二电信号输入输出端通过第二过孔与第二方向条 状电极连接， 而第一电信号输入输出端直接和第一方向条状电极相连。  Alternatively, the first electrical signal input and output end and the second electrical signal input and output end are disposed on the same layer as the first direction strip electrode, and are reserved on the insulating material layer corresponding to the position of the second electrical signal input and output end. The second via, the second electrical signal input and output end is connected to the second direction strip electrode through the second via hole, and the first electrical signal input and output end is directly connected to the first direction strip electrode.
或者， 第一电信号输入输出端和第二电信号输入输出端可以不设置在同 一层， 如果电信号输入输出端和与之连接的条状电极不位于同一层， 则需要 在位于电信号输入输出端与相应的条状电极之间的层中形成用于连接的过 孔。  Alternatively, the first electrical signal input and output end and the second electrical signal input and output end may not be disposed in the same layer. If the electrical signal input and output end and the strip electrode connected thereto are not in the same layer, the electrical signal input is required. A via for connection is formed in the layer between the output and the corresponding strip electrode.
目前， 随着触控屏幕技术的发展， 出现了将触摸屏和三维显示相结合的 3D显示装置，其结构是在三维显示屏上增加一层触控基板，这种结构的制作 过程比较复杂，对于触控基板贴合三维显示屏的对位精度要求比较高， 因此， 整体制作成本相对较高， 并且， 由于触控基板和三维显示屏单独设置， 因此， 得到产品的厚度也比较厚， 此外， 触控基板也会影响三维光栅的显示效果。  At present, with the development of touch screen technology, a 3D display device combining a touch screen and a three-dimensional display has appeared, and the structure thereof is to add a touch substrate on the three-dimensional display screen. The manufacturing process of this structure is complicated. The alignment accuracy of the touch substrate to the three-dimensional display is relatively high. Therefore, the overall manufacturing cost is relatively high, and since the touch substrate and the three-dimensional display are separately provided, the thickness of the product is relatively thick, and The touch substrate also affects the display effect of the three-dimensional grating.
釆用本发明实施例提供的液晶光栅， 在不增加液晶光栅整体厚度且不影 响三维显示的情况下， 不仅能够实现双方向三维光栅显示模式， 还可以实现 电容式触控屏的功能， 下面通过具体实例进行详述。  The liquid crystal grating provided by the embodiment of the present invention can realize the dual-direction three-dimensional raster display mode and the function of the capacitive touch screen without increasing the overall thickness of the liquid crystal grating without affecting the three-dimensional display. Specific examples are described in detail.
在下述实例中， 将本发明实施例提供的液晶光栅中的第一方向条状电极 设置为纵向条状电极， 第二方向条状电极设置为横向条状电极。  In the following examples, the first direction strip electrodes in the liquid crystal grating provided by the embodiment of the present invention are disposed as longitudinal strip electrodes, and the second direction strip electrodes are disposed as lateral strip electrodes.
一般地，触控屏的像素通常在毫米级， 而三维显示的像素通常在微米级， 可以看出， 触控屏所需的驱动电极比屏障栅栏所需的驱动电极要少的多， 可 以将屏障栅栏的横向条状电极或纵向条状电极同时作为驱动液晶偏转的驱动 电极和触控屏的驱动电极， 纵向条状电极或横向条状电极中的一部分作为触 控屏的感应电极， 即可实现触控功能。  Generally, the pixels of the touch screen are usually on the order of millimeters, and the pixels of the three-dimensional display are usually on the order of micrometers. It can be seen that the drive electrodes required by the touch screen are much less than the drive electrodes required for the barrier fence, and The lateral strip electrode or the longitudinal strip electrode of the barrier fence serves as a driving electrode for driving the liquid crystal deflection and a driving electrode of the touch screen, and a part of the vertical strip electrode or the horizontal strip electrode serves as a sensing electrode of the touch screen. Implement touch function.
因此，我们定义每隔 M条的纵向条状电极为触控电极， 除触控电极之外 的纵向条状电极为光栅电极； 定义每隔 N条的横向条状电极为触控电极， 除 触控电极之外的横向条状电极为光栅电极。 其中， 可以根据触控的分辨率设 置 M和 N的数值， 此外， 可以根据液晶光栅的显示屏的长宽比例， 将 M和 N设置成相同数值或不同数值。 Therefore, we define each of the longitudinal strip electrodes of the M strips as the touch electrodes, and the strip electrodes other than the touch electrodes are the grating electrodes; defining every N strip strip electrodes as the touch electrodes, except The lateral strip electrodes outside the touch electrodes are grating electrodes. Wherein, the values of M and N can be set according to the resolution of the touch. In addition, M and N can be set to the same value or different values according to the aspect ratio of the display screen of the liquid crystal grating.
在下述实例中， 将纵向条状电极和横向条状电极的个数设置为 n条， 将 M和 N的数值设置为 2, 即每间隔两条纵向条状电极或横向条状电极为触控 电极， 即第 n条、 第 n-3条、 第 n-6条 ... ...为触控电极。  In the following examples, the number of the vertical strip electrodes and the horizontal strip electrodes is set to n, and the values of M and N are set to 2, that is, the distance between the two longitudinal strip electrodes or the horizontal strip electrodes is touch. The electrodes, that is, the nth, n-3th, and nth-6th... are touch electrodes.
我们将第一电信号输入输出端分为两类， 第一类第一电信号输入输出端 PIN V和多个第二类第一电信号输入输出端 PIN A, 其中， PIN V通过导线 与预先定义为光栅电极的纵向条状电极相连， 一个 PIN A与一个预先定义为 触控电极的纵向条状电极相连， PIN A的个数与纵向条状电极中的触控电极 的个数相同。  We divide the first electrical signal input and output into two categories, a first type of first electrical signal input and output terminal PIN V and a plurality of second type first electrical signal input and output terminals PIN A, wherein PIN V passes through the wire and in advance A longitudinal strip electrode defined as a grating electrode is connected, and a PIN A is connected to a longitudinal strip electrode defined as a touch electrode, and the number of PIN A is the same as the number of touch electrodes in the longitudinal strip electrode.
将第二电信号输入输出端也分为两类， 第一类第二电信号输入输出端 PIN H和多个第二类第二电信号输入输出端 PIN B, 其中， PIN H通过导线 与预先定义为光栅电极的横向条状电极相连， 一个 PIN B与一个预先定义为 触控电极的横向条状电极相连， PIN B的个数与横向条状电极中的触控电极 的个数相同。  The second electrical signal input and output terminals are also divided into two categories, a first type of second electrical signal input and output terminal PIN H and a plurality of second type second electrical signal input and output terminals PIN B, wherein the PIN H passes through the wire and the pre- The horizontal strip electrodes defined as grating electrodes are connected, and one PIN B is connected to a horizontal strip electrode which is defined as a touch electrode, and the number of PIN B is the same as the number of touch electrodes in the lateral strip electrodes.
使用统一的第一类第一电信号输入输出端 PIN V或第一类第二电信号输 入输出端 PIN H向光栅电极输入交流电压信号， 既可以方便电压信号的同步 输入， 也可以减少总的第一电信号输入输出端和第二电信号输入输出端的数 量。  The AC voltage signal is input to the grating electrode by using the unified first type first electric signal input/output terminal PIN V or the first type second electric signal input/output terminal PIN H, which can facilitate the synchronous input of the voltage signal and reduce the total The number of the first electrical signal input and output terminals and the second electrical signal input and output terminals.
实例一： 纵向三维显示和触控功能的实现， 如图 4所示。  Example 1: The realization of vertical three-dimensional display and touch function, as shown in Figure 4.
使用横向条状电极作为屏障栅栏的驱动电极， 即使用 PIN H向与其连接 的光栅电极传递交流电压信号， 具体可以为输入 5V交流电； 使用横向条状 电极中的触控电极作为触控的驱动电极， 即使用 PIN B向与其连接的触控电 极传递与 PIN H相同的交流电压信号， 具体可以为输入 5 V交流电； 使用纵 向条状电极中的触控电极作为感应电极， 即使用 PIN A感应与其连接的触控 电极的电信号。  The horizontal strip electrode is used as the driving electrode of the barrier fence, that is, the PIN H is used to transmit an alternating voltage signal to the grating electrode connected thereto, specifically, inputting 5V alternating current; using the touch electrode in the horizontal strip electrode as the driving electrode of the touch , that is, using the PIN B to transmit the same AC voltage signal as the PIN H to the touch electrode connected thereto, specifically, inputting 5 V alternating current; using the touch electrode in the longitudinal strip electrode as the sensing electrode, that is, using PIN A sensing The electrical signal of the connected touch electrode.
这样， 通电后的横向条状电极和面电极形成了电场， 使得对应的液晶偏 转形成屏障栅栏， 实现了纵向三维光栅显示模式。  Thus, the horizontal strip electrodes and the surface electrodes after energization form an electric field, so that the corresponding liquid crystals are deflected to form a barrier fence, and a longitudinal three-dimensional raster display mode is realized.
通电后的横向条状电极中的触控电极作为触控的驱动电极， 纵向条状电 极中的触控电极作为感应电极， 实现了触控功能。 The touch electrode in the horizontal strip electrode after being energized is used as the driving electrode of the touch, and the longitudinal strip is electrically The touch electrode in the pole is used as the sensing electrode to realize the touch function.
较佳地， 为了增加触控电极间耦合电容， 增加介电常数的同时， 并提高 信噪比， 从而提高触控的灵敏度， 还可以浮置纵向条状电极中的光栅电极， 即使用 PIN V向与其连接的光栅电极输入 0V电压。  Preferably, in order to increase the coupling capacitance between the touch electrodes, increase the dielectric constant, and improve the signal-to-noise ratio, thereby improving the sensitivity of the touch, the grating electrodes in the longitudinal strip electrodes can be floated, that is, the PIN V is used. A voltage of 0 V is input to the grating electrode connected thereto.
实例二： 横向三维显示和触控功能的实现， 如图 5所示。  Example 2: Implementation of horizontal 3D display and touch function, as shown in Figure 5.
使用纵向条状电极作为屏障栅栏的驱动电极， 即使用 PIN V向与其连接 的光栅电极传递交流电压信号， 具体可以为输入 5V交流电； 使用纵向条状 电极中的触控电极作为触控的驱动电极， 即使用 PIN A向与其连接的触控电 极传递与 PIN V相同的交流电压信号， 具体可以为输入 5 V交流电； 使用横 向条状电极中的触控电极作为感应电极， 即使用 PIN B感应与其连接的触控 电极的电信号。  The longitudinal strip electrode is used as the driving electrode of the barrier fence, that is, the AC voltage signal is transmitted to the grating electrode connected thereto by using the PIN V, specifically, the input 5V alternating current is used; the touch electrode in the longitudinal strip electrode is used as the driving electrode of the touch , that is, using the PIN A to transmit the same AC voltage signal as the PIN V to the touch electrode connected thereto, specifically, inputting 5 V alternating current; using the touch electrode in the horizontal strip electrode as the sensing electrode, that is, using the PIN B sensing The electrical signal of the connected touch electrode.
这样， 通电后的纵向条状电极和面电极形成了电场， 使得对应的液晶偏 转形成屏障栅栏， 实现了横向三维光栅显示模式。  Thus, the energized longitudinal strip electrodes and the surface electrodes form an electric field, so that the corresponding liquid crystals are deflected to form a barrier fence, and a lateral three-dimensional raster display mode is realized.
通电后的纵向条状电极中的触控电极作为触控的驱动电极， 横向条状电 极中的触控电极作为感应电极， 实现了触控功能。  The touch electrode in the vertical strip electrode is used as the driving electrode of the touch, and the touch electrode in the horizontal strip electrode is used as the sensing electrode to realize the touch function.
较佳地， 为了增加触控电极间耦合电容， 增加介电常数的同时， 并提高 信噪比， 从而提高触控的灵敏度， 还可以浮置横向条状电极中的光栅电极， 即使用 PIN H向与其连接的光栅电极输入 0V电压。  Preferably, in order to increase the coupling capacitance between the touch electrodes, increase the dielectric constant, and improve the signal-to-noise ratio, thereby improving the sensitivity of the touch, the grating electrodes in the horizontal strip electrodes can be floated, that is, the PIN H is used.
