Abstract
Description
本發明是有關於一種顯示器，且特別是有關於一種具有立體及平面顯示功能並具有觸控感測功能的顯示器。The present invention relates to a display, and more particularly to a display having a stereoscopic and flat display function and having a touch sensing function.
顯示器的設計若要具備有立體顯示功能必須在顯示面板上裝設有像差(parallax)產生裝置，其中常見的像差產生裝置為一延遲片(retarder)。此時，使用者只要配戴特殊的偏光眼鏡觀看顯示器所顯示的畫面，就可以藉由相位延遲片以及偏光眼鏡的作用觀看到立體影像。In order to have a stereoscopic display function, the display panel must be equipped with a parallax generating device, and a common aberration generating device is a retarder. At this time, the user can view the displayed image on the display by wearing special polarized glasses, and the stereoscopic image can be viewed by the action of the phase retarder and the polarized glasses.
詳言之，為了讓使用者看到立體影像，使用者所使用的偏光眼鏡中，左眼鏡片與右眼鏡片的光穿透軸方向不同。顯示器可以透過延遲片的作用，將所顯示的影像光線轉換成僅通過左眼鏡片的偏振狀態或是僅通過右眼鏡片的偏振狀態。如此一來，使用者即可觀看顯示器所顯示的立體影像。In detail, in order to allow the user to see the stereoscopic image, the polarized glasses used by the user have different directions of light transmission axes of the left and right glasses. The display can convert the displayed image light into a polarization state only through the left lens or only through the polarization state of the right lens through the action of the retarder. In this way, the user can view the stereoscopic image displayed on the display.
另外，有一種立體顯示技術是利用像差阻障片(parallax barrier)使顯示影像形成左右眼可視區域，以達到立體顯示效果。具體而言，像差阻障片的設計是在部分區域無法允許光線的通過，而其他的區域可允許光線通過。因此，使用者觀看影像時，有部份區域的顯示光線僅會進入使用者的左眼而另一部份區域的顯示光線則會進入使用者的右眼，藉以實現立體顯示效果。In addition, there is a stereoscopic display technology in which a display image is formed into a visible area of left and right eyes by using a parallax barrier to achieve a stereoscopic display effect. Specifically, the aberration barrier sheet is designed to allow light to pass through in some areas, while other areas allow light to pass through. Therefore, when the user views the image, part of the display light will only enter the user's left eye and the other part of the display light will enter the user's right eye, thereby achieving a stereoscopic display effect.
以目前的電子產品而言，除了立體顯示功能的功能外，具備有觸控感測的產品更是蔚為風潮。然而，要使顯示器同時兼具有這些功能，除了需要在顯示面板上裝設有諸如延遲片或是像差阻障片一類的像差產生裝置外更需要在顯示面板上裝設有觸控面板。不過，顯示器整體體積將增大許多而不利於體積的精簡化。In terms of current electronic products, in addition to the functions of the stereo display function, products with touch sensing are even more popular. However, in order to make the display have these functions at the same time, in addition to the need to install an aberration generating device such as a retardation plate or an aberration blocking plate on the display panel, it is necessary to mount the touch panel on the display panel. . However, the overall size of the display will increase a lot and is not conducive to the simplicity of the volume.
本發明提供一種顯示器，其觸控面板可以整合像差片而兼具有觸控感測功能以及立體顯示功能。The invention provides a display, wherein the touch panel can integrate the aberration sheet and has a touch sensing function and a stereo display function.
本發明提出一種顯示器，包括一顯示面板、一第一基板、一第二基板、一切換液晶層以及一第一導電層。顯示面板用以發出一偏振顯示光。第一基板配置於顯示面板上。第二基板配置於第一基板以及顯示面板之間。切換液晶層配置於第一基板以及第二基板之間。第一導電層配置於第一基板以及切換液晶層之間，且第一導電層包括多個第一長條狀導電結構。當第一導電層處於一觸控感測模式時，第一長條狀導電結構用以感測一觸控電容，並且當第一導電層處於一像差片模式時，第一長條狀導電結構用以驅動切換液晶層而控制偏振顯示光的偏振方向。The invention provides a display comprising a display panel, a first substrate, a second substrate, a switching liquid crystal layer and a first conductive layer. The display panel is configured to emit a polarized display light. The first substrate is disposed on the display panel. The second substrate is disposed between the first substrate and the display panel. The switching liquid crystal layer is disposed between the first substrate and the second substrate. The first conductive layer is disposed between the first substrate and the switching liquid crystal layer, and the first conductive layer includes a plurality of first elongated conductive structures. When the first conductive layer is in a touch sensing mode, the first elongated conductive structure is configured to sense a touch capacitance, and when the first conductive layer is in an aberration mode, the first elongated conductive The structure is used to drive the switching of the liquid crystal layer to control the polarization direction of the polarized display light.
基於上述，本發明利用觸控感測用的導電層來驅動像差片中的切換液晶層，以使觸控面板與像差片整合在一起。如此一來，顯示器可以在不大幅增加體積的前提下兼具觸控感測的功能及立體顯示的功能。Based on the above, the present invention utilizes a conductive layer for touch sensing to drive the switching liquid crystal layer in the aberration sheet to integrate the touch panel and the aberration sheet. In this way, the display can have the functions of touch sensing and stereo display without significantly increasing the volume.
為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
圖1繪示為本發明第一實施例的顯示器的剖面示意圖。請參照圖1，顯示器100包括一顯示面板110、一第一基板120、一第二基板130、一切換液晶層140、一第一偏振片150、一第一導電層160、一第二導電層170以及一保護層180。顯示面板110用以發出偏振顯示光。第一基板120配置於顯示面板110上。第二基板130配置於第一基板120以及顯示面板110之間。切換液晶層140配置於第一基板120以及第二基板130之間。第一偏振片150配置於第一基板120遠離切換液晶層140的一側。第一導電層160配置於第一基板120以及切換液晶層140之間，而第二導電層170配置於第一導電層160以及第一偏振片150之間並位於第一基板120以及第一偏振片150間。此外，保護層180覆蓋住第二導電層170遠離第一基板120的一側。也就是說，保護層180位於第一偏振片150以及第二導電層170之間。1 is a cross-sectional view showing a display according to a first embodiment of the present invention. Referring to FIG. 1 , the display 100 includes a display panel 110 , a first substrate 120 , a second substrate 130 , a switching liquid crystal layer 140 , a first polarizing film 150 , a first conductive layer 160 , and a second conductive layer . 170 and a protective layer 180.

In addition, the protective layer 180 covers the side of the second conductive layer 170 away from the first substrate 120. That is, the protective layer 180 is located between the first polarizing plate 150 and the second conductive layer 170.
在本實施例中，顯示面板110可以由一液晶顯示面板112、一第二偏振片114以及一第三偏振片116所構成。第二偏振片114位於液晶顯示面板112以及第二基板130之間，而液晶顯示面板112位於第三偏振片116與第二偏振片114之間。此外，液晶顯示面板112可以包括兩基板112A、112B、主動元件陣列112C、對向電極112D以及顯示液晶層112E。主動元件陣列112C配置於基板112A上而對向電極112D配置於基板112B上。顯示液晶層112E位於主動元件陣列112C與對向電極112D之間。在一實施例中，主動元件陣列112C可以定義出多個畫素結構(未繪示)以顯示出所需的影像。In this embodiment, the display panel 110 can be composed of a liquid crystal display panel 112, a second polarizing film 114, and a third polarizing film 116. The second polarizer 114 is located between the liquid crystal display panel 112 and the second substrate 130, and the liquid crystal display panel 112 is located between the third polarizer 116 and the second polarizer 114.

In an embodiment, the active device array 112C may define a plurality of pixel structures (not shown) to display the desired image.
詳言之，圖2繪示為第一導電層與第二導電層在一實施例中的上視示意圖。請同時參照圖1與圖2，在本實施例中，第一導電層160包括多個第一長條狀導電結構162，而第二導電層170包括多個第二長條狀導電結構172。第一長條狀導電結構162彼此平行，第二長條狀導電結構172彼此平行，且各第二長條狀導電結構172的延伸方向與各第一長條狀導電結構162的延伸方向相交。第一導電層160與第二導電層170被第一基板120分隔開來而共同構成一互容式設計的觸控感測面板TP。In detail, FIG. 2 is a schematic top view of the first conductive layer and the second conductive layer in an embodiment. Referring to FIG. 1 and FIG. 2 simultaneously, in the embodiment, the first conductive layer 160 includes a plurality of first elongated conductive structures 162, and the second conductive layer 170 includes a plurality of second elongated conductive structures 172. The first elongated conductive structures 162 are parallel to each other, and the second elongated conductive structures 172 are parallel to each other, and the extending direction of each of the second elongated conductive structures 172 intersects with the extending direction of each of the first elongated conductive structures 162. The first conductive layer 160 and the second conductive layer 170 are separated by the first substrate 120 to form a touch sensing panel TP of a mutual capacitive design.
當第一導電層160與第二導電層170處於一觸控感測模式時，第一導電層160與第二導電層170其中一者作為掃描電極，而另一者作為感測電極。也就是說，第一長條狀導電結構162與第二長條狀導電結構172分別可以用來感測使用者的觸碰動作所產生的觸控電容。此時，第一導電層160與第二導電層170可以由同一個驅動晶片所控制。值得一提的是，顯示器100可以是平面顯示模式，其所顯示的影像可為平面影像；另一方面，搭配立體顯示與觸控功能的訊號處理，顯示器100也可以在立體顯示的同時兼具觸控功能。When the first conductive layer 160 and the second conductive layer 170 are in a touch sensing mode, one of the first conductive layer 160 and the second conductive layer 170 serves as a scan electrode, and the other serves as a sensing electrode. That is, the first elongated conductive structure 162 and the second elongated conductive structure 172 can respectively be used to sense the touch capacitance generated by the user's touch action. At this time, the first conductive layer 160 and the second conductive layer 170 may be controlled by the same driving wafer. It is worth mentioning that the display 100 can be in a flat display mode, and the displayed image can be a flat image; on the other hand, with the signal processing of the stereo display and the touch function, the display 100 can also be combined with the stereo display. Touch function.
另外，由於第一導電層160與第二導電層170可以各自獨立地被驅動，顯示器100可選擇性地以另一個驅動晶片來獨立地驅動第一導電層160，藉以控制切換液晶層140的狀態。因此，除了上述的觸控感測模式之外，第一導電層160還可處於一像差片模式。當第一導電層160處於像差片模式時，第一長條狀導電結構162用以驅動切換液晶層140而控制對應的部份切換液晶層140是否允許光線之通過。藉以使得顯示器100處於立體顯示模式。In addition, since the first conductive layer 160 and the second conductive layer 170 can be driven independently of each other, the display 100 can selectively drive the first conductive layer 160 independently with another driving wafer, thereby controlling the state of switching the liquid crystal layer 140. . Therefore, in addition to the above-described touch sensing mode, the first conductive layer 160 may also be in an aberration sheet mode. When the first conductive layer 160 is in the disparity sheet mode, the first elongated conductive structure 162 is used to drive the switching liquid crystal layer 140 to control whether the corresponding partial switching liquid crystal layer 140 allows light to pass. Thereby the display 100 is placed in a stereoscopic display mode.
在本實施例中，第一導電層160由多個處於同一平面上的第一長條狀導電結構162所構成。因此，藉由驅動晶片的控制，顯示器100中的這些第一長條狀導電結構162可以被輸入不同的電壓而使相鄰的第一長條狀導電結構162之間產生平行電場EH。這樣的平行電場EH可以控制切換液晶層140的狀態，藉以使得顯示面板110所發出的偏振顯示光經過切換液晶層140之後選擇性地在特定區域穿透顯示器100或是不穿透顯示器100。In the present embodiment, the first conductive layer 160 is composed of a plurality of first elongated conductive structures 162 on the same plane. Therefore, by controlling the driving of the wafer, the first elongated conductive structures 162 in the display 100 can be input with different voltages to generate a parallel electric field E H between the adjacent first elongated conductive structures 162. Such a parallel electric field E H can control the state of switching the liquid crystal layer 140, so that the polarized display light emitted by the display panel 110 selectively passes through the display 100 or does not penetrate the display 100 in a specific region after switching the liquid crystal layer 140.
也就是說，平行電場EH的控制可以決定每一條第一長條狀導電結構162所對應的位置是否允許光線之穿透。如此一來，第一基板120、第二基板130、切換液晶層140以及第一導電層160可以構成具有阻障功能的像差片RT。當顯示面板110欲進行立體影像的顯示時，對應於部分第一長條狀導電結構162的切換液晶層140處於可透光的狀態，而對應於其他部份第一長條狀導電結構162的切換液晶層140則處於不可透光之狀態。在部份區域的光線無法穿透顯示器100的情況下，顯示面板110所顯示的光線將可以部份進入使用者的左眼而另一部分進入使用者的右眼，以實現立體顯示效果。That is to say, the control of the parallel electric field E H can determine whether the position corresponding to each of the first elongated conductive structures 162 allows light to penetrate. In this way, the first substrate 120, the second substrate 130, the switching liquid crystal layer 140, and the first conductive layer 160 may constitute the aberration sheet RT having a barrier function. When the display panel 110 is to perform the display of the stereoscopic image, the switching liquid crystal layer 140 corresponding to the portion of the first elongated conductive structure 162 is in a light permeable state, and corresponds to the other portions of the first elongated conductive structure 162. The switching liquid crystal layer 140 is in a state of being opaque. In the case that the light in part of the area cannot penetrate the display 100, the light displayed by the display panel 110 may partially enter the left eye of the user and the other part enters the right eye of the user to achieve a stereoscopic display effect.
另外，平行電場EH可以控制切換液晶層140的狀態，以將液晶分子轉換成特定的偏振狀態。因此，當顯示器100中的第一偏振片150被移除後，像差片RT在不同位置可以提供切換液晶層140不同相位延遲的功能。此時，經過像差片RT中不同區域的光線可以同時都穿透顯示器100但是具有不同的偏振特性。因此，使用者配帶有左右鏡片之光穿透軸不同的偏光眼鏡時，左眼與右眼可以接收到不同的畫面而在人腦中產生立體影像。也就是說，在本實施例中，像差片RT整體都可以讓光線穿透，同時可在不同區域提供不同的相位延遲狀態。在這樣的設計下，顯示器100可不需配置有第一偏振片150就可以具有立體顯示功能。也就是說，本實施例的第一偏振片150為選擇性配置於顯示器100中的元件，非限定為必要的元件之一。In addition, the parallel electric field E H can control the state of switching the liquid crystal layer 140 to convert the liquid crystal molecules into a specific polarization state. Therefore, when the first polarizing plate 150 in the display 100 is removed, the disparity sheet RT can provide a function of switching the different phase delays of the liquid crystal layer 140 at different positions. At this time, light passing through different regions in the aberration sheet RT can simultaneously penetrate the display 100 but have different polarization characteristics. Therefore, when the user is equipped with polarized glasses having different light transmission axes of the left and right lenses, the left and right eyes can receive different images and generate stereoscopic images in the human brain. That is to say, in the present embodiment, the aberration sheet RT as a whole can allow light to pass through, and at the same time, different phase delay states can be provided in different regions. Under such a design, the display 100 can have a stereoscopic display function without having to be configured with the first polarizing plate 150. That is, the first polarizing plate 150 of the present embodiment is an element selectively disposed in the display 100, and is not limited to one of the necessary components.
整體而言，顯示器100除了具有平面顯示的功能之外，還具有立體顯示功能以及觸控感測功能。此外，像差片RT或/與觸控感測面板TP共用第一基板120以及第一導電層160，而有助於減少顯示器100所需的構件數量。顯示器100的整體體積不會因此大幅地增加而具有較精簡的體積。In general, the display 100 has a stereoscopic display function and a touch sensing function in addition to the function of the flat display. In addition, the disparity piece RT or/shares the first substrate 120 and the first conductive layer 160 with the touch sensing panel TP to help reduce the number of components required for the display 100. The overall volume of the display 100 does not therefore increase substantially and has a relatively compact size.
圖3繪示為第一導電層與第二導電層在另一實施例中的上視示意圖。請同時參照圖1與圖3，在本實施例中，第一導電層160與第二導電層170同樣地分別包括多條第一長條狀導電結構162以及第二長條狀導電結構172。不過，圖2與圖3所繪示的不同實施例中，第一長條狀導電結構162的寬度設計並不相同。具體而言，在圖3所繪示的實施例中，第一長條狀導電結構162的寬度可以等同於顯示面板110中單一個畫素結構的寬度，而圖2所繪示的實施例中，第一長條狀導電結構162的寬度例如等同於多個畫素結構的寬度，其中單一個畫素結構的寬度可以是90微米(μm)，且相鄰兩條第一長條狀導電結構162之間也可以相隔90微米。3 is a schematic top view of the first conductive layer and the second conductive layer in another embodiment. Referring to FIG. 1 and FIG. 3 simultaneously, in the embodiment, the first conductive layer 160 and the second conductive layer 170 respectively include a plurality of first elongated conductive structures 162 and second elongated conductive structures 172. However, in the different embodiments illustrated in FIG. 2 and FIG. 3, the width design of the first elongated conductive structure 162 is not the same. Specifically, in the embodiment illustrated in FIG. 3, the width of the first elongated conductive structure 162 may be equal to the width of a single pixel structure in the display panel 110, and in the embodiment illustrated in FIG. The width of the first elongated conductive structure 162 is, for example, equivalent to the width of the plurality of pixel structures, wherein the width of the single pixel structure may be 90 micrometers (μm), and the adjacent two first elongated conductive structures 162 can also be separated by 90 microns.
在圖3所繪示的實施例中，第一長條狀導電結構162的寬度等同於畫素結構的寬度，所以顯示面板110在進行立體顯示模式時可以將左眼影像與右眼影像以列反轉(column inversion)的方式顯示出來，不過本發明不以此為限。另外，在觸控感測模式下，第一導電層160的解析度可以大於畫素結構的解析度。因此，多個第一長條狀導電結構162可以連接在一起以進行觸控感測功能。舉例而言，第一導電層160處於像差片模式時，各第一長條狀導電結構162可以彼此電性獨立。第一導電層160處於觸控感測模式時，多個第一感測條162可以透過一連接結構164以選擇性地電性連接在一起。也就是說，連接結構164可以是切換元件。在觸控感測模式下，連接結構164可以將多個第一感測條162電性連接在一起，而在立體顯示模式下，連接結構164可以不將多個第一感測條162電性連接在一起而使得這些第一感測條164彼此電性獨立。In the embodiment illustrated in FIG. 3, the width of the first elongated conductive structure 162 is equal to the width of the pixel structure, so the display panel 110 can display the left eye image and the right eye image when performing the stereoscopic display mode. The column inversion method is displayed, but the invention is not limited thereto. In addition, in the touch sensing mode, the resolution of the first conductive layer 160 may be greater than the resolution of the pixel structure. Therefore, the plurality of first elongated conductive structures 162 can be connected together for touch sensing function. For example, when the first conductive layer 160 is in the disparity sheet mode, each of the first elongated conductive structures 162 may be electrically independent of each other. When the first conductive layer 160 is in the touch sensing mode, the plurality of first sensing strips 162 can be selectively electrically connected together through a connecting structure 164. That is, the connection structure 164 can be a switching element. In the touch sensing mode, the connection structure 164 can electrically connect the plurality of first sensing strips 162 together, and in the stereoscopic display mode, the connection structure 164 can not electrically connect the plurality of first sensing strips 162 Connected together such that the first sensing strips 164 are electrically independent of one another.
圖4繪示為本發明第二實施例的顯示器的剖面示意圖。請參照圖4，顯示器200除了包括有顯示器100的所有構件外，更包括一第三導電層290。因此，顯示器200中的部分構件可參照第一實施例的說明。具體而言，第三導電層290配置於第二基板130與切換液晶層140之間。在本實施例中，第一導電層160處於像差片模式時，第三導電層290以及第一導電層130之間可以產生一垂直電場EV以驅動切換液晶層140。換言之，本實施例採用垂直電場EV來驅動切換液晶層140以使得第一基板120、第二基板130、切換液晶層140、第一導電層160以及第三導電層290共同構成一像差片RT。4 is a cross-sectional view showing a display according to a second embodiment of the present invention. Referring to FIG. 4, the display 200 includes a third conductive layer 290 in addition to all the components of the display 100. Therefore, some of the components in the display 200 can be referred to the description of the first embodiment. Specifically, the third conductive layer 290 is disposed between the second substrate 130 and the switching liquid crystal layer 140. In the embodiment, when the first conductive layer 160 is in the disparity sheet mode, a vertical electric field E V may be generated between the third conductive layer 290 and the first conductive layer 130 to drive the switching liquid crystal layer 140. In other words, the present embodiment uses the vertical electric field E V to drive the switching liquid crystal layer 140 such that the first substrate 120, the second substrate 130, the switching liquid crystal layer 140, the first conductive layer 160, and the third conductive layer 290 together constitute an aberration sheet. RT.
相似於第一實施例，第一導電層160、第二導電層170以及夾於兩導電層中間的第一基板120共同構成觸控感測面板TP。所以，在顯示器200中，觸控感測面板TP與像差片RT共用第一導電層160以及第一基板120而有助於精簡整體體積。另外，在本實施例中，第一導電層160與第二導電層170的上視圖可以參照圖2或是圖3所繪示的態樣。也就是說，第一導電層160與第二導電層170可以分別由多個長條狀導電結構所構成。Similar to the first embodiment, the first conductive layer 160, the second conductive layer 170, and the first substrate 120 sandwiched between the two conductive layers collectively constitute the touch sensing panel TP. Therefore, in the display 200, the touch sensing panel TP and the disparity sheet RT share the first conductive layer 160 and the first substrate 120 to help reduce the overall volume. In addition, in this embodiment, a top view of the first conductive layer 160 and the second conductive layer 170 may refer to the aspect illustrated in FIG. 2 or FIG. 3. That is, the first conductive layer 160 and the second conductive layer 170 may each be composed of a plurality of elongated conductive structures.
值得一提的是，第三導電層290也可以由多個彼此平行的第三長條狀導電結構(未繪示)所組成，且各第三長條狀導電結構(未繪示)的延伸方向與第一導電層160的各第一長條狀導電結構的延伸方向相交。此時，第一導電層160與第三導電層290之間所形成的垂直電場EV可以呈現特定的分布以實現局部立體顯示的功能。詳言之，各第一長條狀導電結構以及各第三長條狀導電結構可以獨立地被驅動。並且，第一長條狀導電結構與第三長條狀導電結構相交構成多個重疊面積。在不同重疊面積中，垂直電場EV可以不同。此時，第一導電層160與第三導電層290例如以被動矩陣的驅動方式(passive matrix driving method)來驅動切換液晶層140。因此，像差片RT所提供的相位延遲可以呈現特定的分布而在局部區域實現立體顯示功能且局部區域實現平面顯示功能。It is to be noted that the third conductive layer 290 may also be composed of a plurality of third elongated conductive structures (not shown) that are parallel to each other, and an extension of each of the third elongated conductive structures (not shown). The direction intersects the extending direction of each of the first elongated conductive structures of the first conductive layer 160. At this time, the vertical electric field E V formed between the first conductive layer 160 and the third conductive layer 290 may exhibit a specific distribution to realize the function of partial stereoscopic display. In detail, each of the first elongated conductive structures and each of the third elongated conductive structures may be independently driven. Moreover, the first elongated conductive structure intersects with the third elongated conductive structure to form a plurality of overlapping areas. The vertical electric field E V can be different in different overlapping areas. At this time, the first conductive layer 160 and the third conductive layer 290 drive the switching liquid crystal layer 140, for example, in a passive matrix driving method. Therefore, the phase delay provided by the aberration sheet RT can present a specific distribution while realizing a stereoscopic display function in a partial area and a planar display function in a partial area.
圖5繪示為本發明第三實施例的顯示器的剖面示意圖。請參照圖5，顯示器300實質上與顯示器100大致相同，以下僅就兩實施例的不同點進行說明。在本實施例中，第二導電層170可選擇性地設置於第一基板120與第一導電層160之間，且第一導電層160與第二導電層170之間配置有一絕緣層380。也就是說，本實施例係將第一導電層160與第二導電層170同時設置於第一基板120接近於切換液晶層140的一側。FIG. 5 is a cross-sectional view showing a display according to a third embodiment of the present invention. Referring to FIG. 5, the display 300 is substantially the same as the display 100. Hereinafter, only differences between the two embodiments will be described. In this embodiment, the second conductive layer 170 is selectively disposed between the first substrate 120 and the first conductive layer 160, and an insulating layer 380 is disposed between the first conductive layer 160 and the second conductive layer 170. That is to say, in the embodiment, the first conductive layer 160 and the second conductive layer 170 are simultaneously disposed on a side of the first substrate 120 close to the switching liquid crystal layer 140.
顯示器300進行立體顯示時，第一導電層160與第二導電層170可以共同形成一邊緣電場EF以驅動切換液晶層140。也就是說，在本實施例中，第一基板120、第一導電層160、絕緣層380以及第二導電層170共同構成觸控感測面板TP，而第一基板、第一導電層160、絕緣層380、第二導電層170、切換液晶層140以及第二基板130共同構成像差片RT。此時，像差片RT已經包括了觸控感測面板TP的所有構件，因而有助於精簡顯示器300的整體體積。When the display 300 performs stereoscopic display, the first conductive layer 160 and the second conductive layer 170 may together form a fringe electric field E F to drive the switching liquid crystal layer 140. In other words, in the embodiment, the first substrate 120, the first conductive layer 160, the insulating layer 380, and the second conductive layer 170 together constitute the touch sensing panel TP, and the first substrate, the first conductive layer 160, The insulating layer 380, the second conductive layer 170, the switching liquid crystal layer 140, and the second substrate 130 collectively constitute the aberration sheet RT. At this time, the aberration sheet RT already includes all the components of the touch sensing panel TP, thereby contributing to the reduction of the overall volume of the display 300.
圖6繪示為本發明第四實施例的顯示器的剖面示意圖。請參照圖6，顯示器400實質上與顯示器200大致相同，以下僅就本實施例不同於顯示器200的部份進行說明。在本實施例中，第二導電層170可選擇性地設置於第一基板120與第一導電層160之間，且第一導電層160與第二導電層170之間配置有一絕緣層480。也就是說，本實施例係將第一導電層160與第二導電層170同時設置於第一基板120接近於切換液晶層140的一側。在本實施例中，顯示器400進行立體顯示時，第二導電層170例如不被驅動，而第一導電層160與第三導電層290被驅動以形成控制切換液晶層140的垂直電場EV。此外，若欲進行觸控感測，則第三導電層290不被驅動，僅以第一導電層160與第二導電層170進行觸控感測功能。6 is a cross-sectional view showing a display according to a fourth embodiment of the present invention. Referring to FIG. 6, the display 400 is substantially the same as the display 200. Hereinafter, only the portion of the embodiment different from the display 200 will be described. In the present embodiment, the second conductive layer 170 is selectively disposed between the first substrate 120 and the first conductive layer 160, and an insulating layer 480 is disposed between the first conductive layer 160 and the second conductive layer 170. That is to say, in the embodiment, the first conductive layer 160 and the second conductive layer 170 are simultaneously disposed on a side of the first substrate 120 close to the switching liquid crystal layer 140. In the present embodiment, when the display 400 performs stereoscopic display, the second conductive layer 170 is not driven, for example, and the first conductive layer 160 and the third conductive layer 290 are driven to form a vertical electric field E V that controls the switching liquid crystal layer 140. In addition, if the touch sensing is to be performed, the third conductive layer 290 is not driven, and only the first conductive layer 160 and the second conductive layer 170 perform a touch sensing function.
