Description
本發明是有關於一種觸控式顯示面板，且特別是有關於一種內嵌式電阻觸控顯示面板。 The present invention relates to a touch display panel, and more particularly to an in-cell resistive touch display panel.
隨著資訊技術、無線行動通訊和資訊家電的快速發展與應用，為了達到攜帶更便利、體積更輕巧化以及操作更人性化的目的，許多資訊產品已由傳統之鍵盤或滑鼠等輸入裝置，轉變為使用觸控面板(Touch Panel)作為輸入裝置。目前，觸控面板大致可區分為電阻式、電容式、光學式、聲波式及電磁式等觸控面板，其中以電阻式觸控面板與電容式觸控面板為最常見的產品。就電容式觸控面板而言，可多點觸控的特性提供更人性化的操作模式，使得電容式觸控面板逐漸受到市場的青睞。 With the rapid development and application of information technology, wireless mobile communication and information appliances, in order to achieve more convenient carrying, lighter weight and more user-friendly operation, many information products have been input devices such as traditional keyboards or mice. Switching to using a touch panel as an input device. Currently, touch panels can be roughly classified into resistive, capacitive, optical, acoustic, and electromagnetic touch panels. Among them, resistive touch panels and capacitive touch panels are the most common products. In the case of a capacitive touch panel, the multi-touch feature provides a more user-friendly operation mode, and the capacitive touch panel is gradually favored by the market.
所謂內嵌式觸控顯示面板是將觸控面板內嵌於顯示面板內。而對於內嵌式電阻觸控顯示面板來說，當使用者對觸控顯示面板進行按壓以作觸控操作時，外壓的力量往往會對顯示面板的玻璃基板造成形變，如此將使顯示面板內的液晶產生擾流而改變了顯示面板的延遲值(retardation)。因此，人眼便會在按壓處看到有嚴重的顯示瑕疵(mura)，特別是在拖曳觸控時，顯示瑕疵(mura)的情況將更為嚴重，如此使的顯示面板的光學特性下降。 The so-called in-cell touch display panel embeds the touch panel in the display panel. For the in-cell resistive touch display panel, when the user presses the touch display panel for the touch operation, the external pressure tends to deform the glass substrate of the display panel, thus the display panel is The liquid crystal inside generates a turbulence which changes the retardation of the display panel. Therefore, the human eye will see a serious display mura at the pressing place, especially when the touch is dragged, the situation of displaying the mura will be more serious, so that the optical characteristics of the display panel are degraded.
本發明提供一種觸控式顯示面板，其可以解決當對觸控顯示面板進行按壓以作觸控操作時因液晶擾流所造成的顯示瑕疵(mura)的問題。 The present invention provides a touch display panel that can solve the problem of display mura caused by liquid crystal turbulence when the touch display panel is pressed for a touch operation.

The touch-sensitive display panel includes a first substrate and a second substrate. The plurality of touch structures include a plurality of touch spacers and a plurality of sensing electrodes, wherein the touch spacers and the sensing electrodes are respectively located on the first substrate and the second substrate Each of the touch spacers and the corresponding sensing electrode has a first gap (G 1 ); and a barrier wall structure is located on one of the first substrate and the second substrate, wherein the barrier wall structure is located in the pixel a light-shielding region of the region, the barrier wall structure and the other of the first substrate and the second substrate have a second gap (G 2 ), and G 1 <G 2 <4G 1 ; and a display medium are located at the first Between the substrate and the second substrate.
本發明提出另一種觸控式顯示面板，其具有多個畫素區域，且每一畫素區域具有一遮光區以及一透光區，此觸控式顯示面板包括一第一基板；一第二基板，位於第一基板的對向；多個觸控結構，其包含多個觸控間隙物以及多個感應電極，所述觸控間隙物以及所述感應電極分別位於第一基板與第二基板上，其中每一觸控間隙物與對應的感應電極之間具有一第一間隙(G1)；一第一阻隔牆結構以及一第二阻隔牆結構，分別位於第一基板以及第二基板上，其中第一與第二阻隔牆結構位於畫素區域的遮光區內，第 一阻隔牆結構與第二阻隔牆結構之間具有一第二間隙(G2)，且G1<G2<4G1；以及一顯示介質，位於第一基板與第二基板之間。 The touch-sensitive display panel has a plurality of pixel regions, and each pixel region has a light-shielding region and a light-transmitting region. The touch-sensitive display panel includes a first substrate; The substrate is located opposite to the first substrate; the plurality of touch structures include a plurality of touch spacers and a plurality of sensing electrodes, wherein the touch spacers and the sensing electrodes are respectively located on the first substrate and the second substrate a first gap (G 1 ) is disposed between each touch spacer and the corresponding sensing electrode; a first barrier wall structure and a second barrier wall structure are respectively located on the first substrate and the second substrate The first and second barrier wall structures are located in the light-shielding region of the pixel region, and the second barrier wall structure and the second barrier wall structure have a second gap (G 2 ), and G 1 <G 2 <4G 1 ; and a display medium between the first substrate and the second substrate.
基於上述，本發明因於顯示面板內設計阻隔牆結構，因此當進行按壓之觸控操作時，阻隔牆結構可以將液晶侷限於特定區域，使得液晶擾動程度降低。如此一來，顯示面板的延遲值不易被改變，因而可以改善按壓處的顯示瑕疵(mura)之問題。 Based on the above, the present invention is designed to have a barrier wall structure in the display panel. Therefore, when the touch operation is performed, the barrier wall structure can restrict the liquid crystal to a specific area, so that the degree of liquid crystal disturbance is reduced.

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是根據本發明之一實施例的觸控式顯示面板的局部示意圖。圖2是圖1在I-I’、II-II’以及III-III’的剖面示意圖。請參照圖1以及圖2，本實施例之觸控式顯示面板具有多個畫素區域110，每一畫素區域110具有一透光區120以及一遮光區130。為了清楚說明，圖中僅標示出其中一畫素區域以及此畫素區域內的透光區與遮光區為例來說明。更詳細而言，在畫素區域110中，沒有被金屬線或是遮光膜層或元件所遮蔽之區域即定義為透光區120；而設置有金屬線、或是遮光膜層或元件之區域即定義為遮光區130。 1 is a partial schematic view of a touch display panel in accordance with an embodiment of the present invention. Figure 2 is a schematic cross-sectional view of Figure 1 at I-I', II-II' and III-III'. Referring to FIG. 1 and FIG. 2 , the touch display panel of the embodiment has a plurality of pixel regions 110 , and each of the pixel regions 110 has a light transmissive region 120 and a light shielding region 130 . For the sake of clarity, only one of the pixel regions and the light-transmitting region and the light-shielding region in the pixel region are illustrated as an example. In more detail, in the pixel region 110, a region not covered by a metal wire or a light shielding film layer or an element is defined as a light transmitting region 120; and a metal wire or a light shielding film layer or an element region is provided. That is, it is defined as the light shielding area 130.
上述之觸控式顯示面板包括第一基板100、第二基板180以及位於兩基板100、180之間的顯示介質162。顯示 介質162包括液晶分子或是其他的顯示介質。 The above touch display panel includes a first substrate 100, a second substrate 180, and a display medium 162 between the substrates 100, 180. display The medium 162 includes liquid crystal molecules or other display media.
在本實施例中，第一基板100為主動元件陣列基板，因此第一基板100上設置有一主動元件陣列層152。更詳細而言，主動元件陣列層152包括掃描線SL、資料線DL以及與掃描線SL及資料線DL電性連接的主動元件102。主動元件102例如是薄膜電晶體，其具有閘極、源極以及汲極。而掃描線SL、資料線DL與主動元件102皆設置於畫素區域的遮光區130中。因此，在掃描線SL與資料線DL所圍出的區域的內部即為透光區120，因而遮光區130是位於透光區120的外圍。在另一實施例中，主動元件陣列層152更包括電容電極線C，其與掃描線SL平行設置。若主動元件陣列層152具有電容電極線C之設計，那麼畫素區域110的遮光區130還包括了電容電極線C所在的區域。 In the embodiment, the first substrate 100 is an active device array substrate, and thus the active device array layer 152 is disposed on the first substrate 100. In more detail, the active device array layer 152 includes a scan line SL, a data line DL, and an active device 102 electrically connected to the scan line SL and the data line DL. The active component 102 is, for example, a thin film transistor having a gate, a source, and a drain. The scan line SL, the data line DL and the active device 102 are all disposed in the light blocking area 130 of the pixel area. Therefore, the inside of the region surrounded by the scanning line SL and the data line DL is the light transmitting region 120, and thus the light shielding region 130 is located at the periphery of the light transmitting region 120. In another embodiment, the active device array layer 152 further includes a capacitor electrode line C that is disposed in parallel with the scan line SL. If the active device array layer 152 has a design of the capacitor electrode line C, the light shielding region 130 of the pixel region 110 further includes the region where the capacitor electrode line C is located.
另外，第一基板上110除了上述之主動元件陣列層152之外，在主動元件陣列層152上還包括有畫素電極104以及感應電極106。畫素電極104是設置於每一畫素區域110內的透光區域120中。在其他實施例中，畫素電極104也可以延伸至遮光區域130。特別是，每一畫素區域110內的畫素電極104與主動元件102電性連接。例如，畫素電極104是透過接觸窗H與主動元件102的其中一電極(例如是薄膜電晶體的汲極)電性連接。 In addition, the first substrate 110 further includes a pixel electrode 104 and a sensing electrode 106 on the active device array layer 152 in addition to the active device array layer 152 described above. The pixel electrode 104 is disposed in the light transmissive region 120 in each of the pixel regions 110. In other embodiments, the pixel electrode 104 can also extend to the light blocking region 130. In particular, the pixel electrode 104 in each pixel region 110 is electrically connected to the active device 102. For example, the pixel electrode 104 is electrically connected to one of the electrodes of the active device 102 (for example, the drain of the thin film transistor) through the contact window H.
第二基板180是位於第一基板100的對向。在本實施例中，第二基板180為一彩色濾光陣列基板。更詳細而言， 在第二基板180上還包括設置有黑矩陣層184、彩色濾光層182以及電極層186。黑矩陣層184是設置於每一畫素區域110的遮光區130中，因此黑矩陣層184呈現棋盤格狀的佈局。而彩色濾光層182設置在每一畫素區域110的透光區120中，且其包括紅、綠、藍濾光圖案。另外，電極層186覆蓋黑矩陣層184以及彩色濾光層182。 The second substrate 180 is located opposite to the first substrate 100. In this embodiment, the second substrate 180 is a color filter array substrate. In more detail, Further included on the second substrate 180 is a black matrix layer 184, a color filter layer 182, and an electrode layer 186. The black matrix layer 184 is disposed in the light-shielding region 130 of each pixel region 110, and thus the black matrix layer 184 exhibits a checkerboard-like layout. The color filter layer 182 is disposed in the light transmissive region 120 of each pixel region 110, and includes red, green, and blue filter patterns. In addition, the electrode layer 186 covers the black matrix layer 184 and the color filter layer 182.
另外，第二基板180上更包括設置有觸控間隙物150，且電極層186覆蓋觸控間隙物150的表面。觸控間隙物150是設置於畫素區域110的遮光區130中，因此觸控間隙物150是位於黑矩陣層184的上方。在本實施例中，觸控間隙物150是對應第一基板100的掃描線SL設置。特別是，每一觸控間隙物150之對向側都會設置有一感應電極106，且每一觸控間隙物150與對應的感應電極106之間具有一第一間隙(G1)，因此觸控間隙物150與感應電極106構成一觸控結構105。更詳細來說，第一間隙(G1)指的是觸控間隙物150上的電極層186表面與感應電極106表面之間的距離。當對此觸控式顯示面板進行按壓的觸控操作時，觸控間隙物150表面的電極層186會與對向側的感應電極106接觸，進而得知觸控位置。 In addition, the second substrate 180 further includes a touch spacer 150 disposed thereon, and the electrode layer 186 covers the surface of the touch spacer 150 . The touch spacer 150 is disposed in the light shielding region 130 of the pixel region 110 , and thus the touch spacer 150 is located above the black matrix layer 184 . In the embodiment, the touch spacer 150 is disposed corresponding to the scan line SL of the first substrate 100. In particular, a sensing electrode 106 is disposed on the opposite side of each touch spacer 150, and a first gap (G 1 ) is formed between each touch spacer 150 and the corresponding sensing electrode 106. The spacer 150 and the sensing electrode 106 form a touch structure 105. In more detail, the first gap (G 1 ) refers to the distance between the surface of the electrode layer 186 on the touch spacer 150 and the surface of the sensing electrode 106. When the touch operation is performed on the touch display panel, the electrode layer 186 on the surface of the touch spacer 150 contacts the opposite side of the sensing electrode 106 to know the touch position.
在一較佳實施例中，在第二基板180還包括設置有主間隙物160以及次間隙物170。主間隙物160是位於電極層186的表面上，且主間隙物160的頂端與第一基板100上的膜層152接觸，主間隙物160主是用來維持第一與第二基板100、180之間的間隙G。次間隙物170是位於黑矩 陣層184上，且電極層186覆蓋次間隙物170。而次間隙物170與第一基板100上的膜層152並未接觸，而是保持有一定的間隙。次間隙物170主是功能是輔助主間隙物160之用，也就是當有外力衝擊顯示面板時，次間隙物170得以提供一反作用力以支撐第一與第二基板100、180之間保有間隙G。 In a preferred embodiment, the second substrate 180 further includes a main spacer 160 and a secondary spacer 170. The main spacer 160 is located on the surface of the electrode layer 186, and the top end of the main spacer 160 is in contact with the film layer 152 on the first substrate 100. The main spacer 160 is mainly used to maintain the first and second substrates 100, 180. The gap between G. The secondary spacer 170 is located at the black moment On the array 184, and the electrode layer 186 covers the secondary spacer 170. The spacers 170 are not in contact with the film layer 152 on the first substrate 100, but maintain a certain gap. The secondary spacer 170 is mainly used to assist the main spacer 160, that is, when an external force impacts the display panel, the secondary spacer 170 provides a reaction force to support the gap between the first and second substrates 100, 180. G.
特別是，在本實施例中，第一基板100上更包括設置有一阻隔牆結構140，或可稱為顯示域隔牆(Domain wall)結構。阻隔牆結構140是位於畫素區域110的遮光區130內，且阻隔牆結構140與第二基板180之間具有一第二間隙(G2)。更詳細來說，第二間隙(G2)是阻隔牆結構140表面與第二基板180上之電極層186表面之間的距離。在此，第一間隙(G1)與第二間隙(G2)之間的關係為G1<G2<4G1。另外，第一基板100與第二基板180之間的間隙G與第二間隙(G2)之間的關係為G2<1/2G。換言之，第二間隙(G2)的大小需大於第一間隙(G1)的大小，如此阻隔牆結構140才不會影響觸控間隙物150與感應電極106之間的接觸感應。而且，第二間隙(G2)的大小又不能太大，較佳的是小於4G1，且不能大於第一基板100與第二基板180之間的間隙G的一半，且更佳是第一間隙(G1)與第二間隙(G2)之間的關係為1.1G1<G2<2.5G1。如此才能將液晶有效的侷限於特定區域以降低液晶擾動程度。舉例來說，若第一間隙(G1)為0.4微米，第二間隙(G2)可為0.5~1微米。 In particular, in the embodiment, the first substrate 100 further includes a barrier wall structure 140, or may be referred to as a display domain wall structure. The barrier wall structure 140 is located in the light shielding region 130 of the pixel region 110, and has a second gap (G 2 ) between the barrier wall structure 140 and the second substrate 180. In more detail, the second gap (G 2 ) is the distance between the surface of the barrier wall structure 140 and the surface of the electrode layer 186 on the second substrate 180. Here, the relationship between the first gap (G 1 ) and the second gap (G 2 ) is G 1 <G 2 <4G 1 . Further, the relationship between the gap G between the first substrate 100 and the second substrate 180 and the second gap (G 2 ) is G 2 < 1/2G. In other words, the size of the second gap (G 2 ) needs to be larger than the size of the first gap (G 1 ), so that the barrier structure 140 does not affect the contact sensing between the touch gap 150 and the sensing electrode 106. Moreover, the size of the second gap (G 2 ) is not too large, preferably less than 4G 1 , and cannot be greater than half of the gap G between the first substrate 100 and the second substrate 180, and more preferably the first The relationship between the gap (G 1 ) and the second gap (G 2 ) is 1.1G 1 <G 2 <2.5G 1 . In this way, the liquid crystal can be effectively limited to a specific area to reduce the degree of liquid crystal disturbance. For example, if the first gap (G 1 ) is 0.4 μm, the second gap (G 2 ) may be 0.5 to 1 μm.
另外，在本實施例中，每一畫素區域110內的阻隔牆 結構140所佔的面積為畫素區域110的面積的4~35%。由於阻隔牆結構140可以有多種不同的設計，且每一畫素區域110內的阻隔牆結構可以完全相同或是不完全相同，因此每一畫素區域110內的阻隔牆結構140所佔的面積可介於畫素區域110的面積的4~35%的範圍。另外，阻隔牆結構140是位於畫素區域110的遮光區130內，較佳的是，阻隔牆結構140的邊緣與畫素區域110之遮光區130之邊緣相距1.5~5微米的距離。此外，在本實施例中，阻隔牆結構140的頂部寬度小於底部寬度，因此阻隔牆結構140的側壁與第一基板100之表面的夾角為50~90度。再者，阻隔牆結構140的材料可為透明介電材料或是非透明介電材料，且其介電係數介於1~5。 In addition, in the present embodiment, the barrier wall in each pixel area 110 The area occupied by the structure 140 is 4 to 35% of the area of the pixel area 110. Since the barrier wall structure 140 can have a plurality of different designs, and the barrier wall structures in each of the pixel regions 110 can be identical or not identical, the area occupied by the barrier wall structure 140 in each pixel region 110 It may be in the range of 4 to 35% of the area of the pixel area 110. In addition, the barrier wall structure 140 is located in the light-shielding region 130 of the pixel region 110. Preferably, the edge of the barrier wall structure 140 is at a distance of 1.5 to 5 micrometers from the edge of the light-shielding region 130 of the pixel region 110. In addition, in the embodiment, the top width of the barrier wall structure 140 is smaller than the bottom width, so the angle between the sidewall of the barrier wall structure 140 and the surface of the first substrate 100 is 50 to 90 degrees. Furthermore, the material of the barrier wall structure 140 may be a transparent dielectric material or a non-transparent dielectric material, and has a dielectric constant of 1 to 5.
當對圖2之顯示面板進行觸控操作時如圖3所示，也就是，當有外力200對顯示面板進行按壓觸控操作時，按壓區域因外力200作用而使第二基板180以及其上的膜層產生形變，進而使觸控間隙物150上的電極層186與感應電極106接觸。此時因為第二基板180以及其上的膜層產生形變，因此此處的液晶分子162會因基板的形變而往四周擾流，但本實施例因在畫素區域110的遮光區130中設置有阻隔牆結構140，因此在此畫素區域110內大部分的液晶分子162將被侷限於阻隔牆結構140所圍出的區域內，因而有效地防止液晶分子140任意擾流。 When the touch operation is performed on the display panel of FIG. 2, as shown in FIG. 3, that is, when the external force 200 presses the touch operation on the display panel, the pressing area acts on the second substrate 180 and the upper surface thereof due to the external force 200. The film layer is deformed to contact the electrode layer 186 on the touch spacer 150 with the sensing electrode 106. At this time, since the second substrate 180 and the film layer thereon are deformed, the liquid crystal molecules 162 here are disturbed to the surroundings due to the deformation of the substrate, but the present embodiment is provided in the light shielding region 130 of the pixel region 110. There is a barrier wall structure 140, so that most of the liquid crystal molecules 162 in the pixel region 110 will be limited to the area enclosed by the barrier wall structure 140, thereby effectively preventing the liquid crystal molecules 140 from arbitrarily disturbing.
請在參照圖1，在本實施例中，阻隔牆結構140是形成在每一畫素區域110的周邊，以包圍每一畫素區域110 的透光區120。也就是阻隔牆結構140在每一畫素區域110是封閉的環狀結構，但本發明不限於此。在其他的實施例中，阻隔牆結構還可以是其他種設計。如以下圖4至圖7之實施例。 Referring to FIG. 1, in the present embodiment, a barrier wall structure 140 is formed at the periphery of each pixel region 110 to surround each pixel region 110. Light transmissive area 120. That is, the barrier wall structure 140 is a closed annular structure in each of the pixel regions 110, but the present invention is not limited thereto. In other embodiments, the barrier wall structure can also be of other designs. The embodiments of Figures 4 to 7 below are as follows.
請參照圖4，圖4之實施例之觸控式顯示面板之結構與圖1之結構相似，不同之處在於此實施例之阻隔牆結構140具有一主體部140a以及一分支部140b。主體部140a位於每一畫素區域110的周邊，以包圍每一畫素區域110的透光區120，因此主體部140a在每一畫素區域110是封閉的環狀結構。而分支部140b是位於每一畫素區域110之設置有電容電極線C之處。因此，分支部140b可將每一畫素區域110內的液晶分子分成兩個區域來達到侷限液晶擾流的效果。 Referring to FIG. 4, the structure of the touch display panel of the embodiment of FIG. 4 is similar to that of FIG. 1. The barrier wall structure 140 of this embodiment has a main body portion 140a and a branch portion 140b. The main body portion 140a is located at the periphery of each of the pixel regions 110 to surround the light transmissive region 120 of each of the pixel regions 110, and thus the main body portion 140a is a closed annular structure in each of the pixel regions 110. The branch portion 140b is located at a position where the capacitor electrode line C is disposed in each of the pixel regions 110. Therefore, the branch portion 140b can divide the liquid crystal molecules in each of the pixel regions 110 into two regions to achieve the effect of limiting the liquid crystal spoiler.
請參照圖5，圖5之實施例之觸控式顯示面板之結構與圖1之結構相似，不同之處在於此實施例之阻隔牆結構140具有一主體部140c、一分支部140b以及至少一側向開口144。主體部140c位於每一畫素區域110的周邊，但主體部140c於對應掃描線SL處具有側向開口144。因此，主體部140c在每一畫素區域110並非封閉環狀結構。此側向開口144之設計可以使得畫素區域110內的液晶在遭到按壓時僅能往對應設置有掃描線SL處流動(如箭頭146方向)。而由於設置有掃描線SL之區域有較寬裕的遮光區130，因而擾流的液晶在此處不會造成漏光的情形。另外，分支部140b是位於每一畫素區域110之設置有電容電極線 C之處。同樣地，分支部140b可將每一畫素區域110內的液晶分子分成兩個區域來達到限制液晶擾流的效果。 Referring to FIG. 5 , the structure of the touch display panel of the embodiment of FIG. 5 is similar to the structure of FIG. 1 , except that the barrier wall structure 140 of the embodiment has a main body portion 140 c , a branch portion 140 b , and at least one Lateral opening 144. The body portion 140c is located at the periphery of each pixel region 110, but the body portion 140c has a lateral opening 144 at the corresponding scan line SL. Therefore, the main body portion 140c is not a closed loop structure in each of the pixel regions 110. The lateral opening 144 is designed such that the liquid crystal in the pixel region 110 can only flow toward the corresponding scan line SL (as indicated by the arrow 146) when pressed. Since the area where the scanning line SL is provided has a relatively large light-shielding area 130, the disturbed liquid crystal does not cause light leakage there. In addition, the branch portion 140b is provided with a capacitor electrode line located in each pixel region 110. C. Similarly, the branch portion 140b can divide the liquid crystal molecules in each of the pixel regions 110 into two regions to achieve the effect of restricting liquid crystal spoiler.
請參照圖6，圖6之實施例之觸控式顯示面板之結構與圖1之結構相似，不同之處在於此實施例之阻隔牆結構140位於三個畫素區域的周邊，以包圍三個畫素區域110的透光區120。因此，此阻隔牆結構140為圍繞三個畫素區域110的封閉環狀結構。然，本發明不限阻隔牆結構140所圍繞的畫素區域110的數目，換言之，在其他的實施例中，阻隔牆結構140可以是圍繞一個、兩個、或是更多畫素區域的封閉環狀結構。 Referring to FIG. 6 , the structure of the touch display panel of the embodiment of FIG. 6 is similar to the structure of FIG. 1 , except that the barrier wall structure 140 of the embodiment is located at the periphery of the three pixel regions to surround the three. The light transmitting region 120 of the pixel region 110. Therefore, the barrier wall structure 140 is a closed loop structure surrounding the three pixel regions 110. However, the present invention is not limited to the number of pixel regions 110 surrounded by the barrier wall structure 140, in other words, in other embodiments, the barrier wall structure 140 may be closed around one, two, or more pixel regions. Ring structure.
請參照圖7，圖7之實施例之觸控式顯示面板之結構與圖1之結構相似，不同之處在於此實施例之阻隔牆結構140具有一主體部140a以及一分支部140b。主體部140a位於三個畫素區域的周邊，以包圍每一畫素區域110的透光區120。因此，主體部140a為圍繞三個畫素區域110的封閉環狀結構。類似地，本發明不限主體部140a所圍繞的畫素區域110的數目，換言之，在其他的實施例中，主體部140a可以是圍繞一個、兩個、或是更多畫素區域的封閉環狀結構。而分支部140b是位於畫素區域110之設置有電容電極線C之處。因此，分支部140b可將主體部140a所圍出的區域內的液晶分子分成兩個區域來達到侷限液晶擾流的效果。 Referring to FIG. 7, the structure of the touch display panel of the embodiment of FIG. 7 is similar to that of FIG. 1. The barrier wall structure 140 of this embodiment has a main body portion 140a and a branch portion 140b. The body portion 140a is located at the periphery of the three pixel regions to surround the light transmitting region 120 of each of the pixel regions 110. Therefore, the main body portion 140a is a closed annular structure surrounding the three pixel regions 110. Similarly, the present invention is not limited to the number of pixel regions 110 surrounded by the body portion 140a, in other words, in other embodiments, the body portion 140a may be a closed ring surrounding one, two, or more pixel regions. Structure. The branch portion 140b is located at the pixel region C where the capacitor electrode line C is disposed. Therefore, the branch portion 140b can divide the liquid crystal molecules in the region surrounded by the main body portion 140a into two regions to achieve the effect of limiting the liquid crystal spoiler.
上述數個實施例之觸控式顯示面板中，阻隔牆結構140都是設置於第一基板100上，但是本發明不限於此。 在其他的實施例中，阻隔牆結構140也可以設置在第二基板180上，如圖8所示，阻隔牆結構140是設置於第二基板180上的電極層186表面上。在圖8的實施例中，除了阻隔牆結構140是設置於第二基板180上與先前數個實施例不同之外，其他的組成結構(例如觸控間隙物與感應電極的設置以及主間隙物與次間隙物的設置等等)皆相同或相似。另外，設置於第二基板180上的阻隔牆結構140的佈局可以是圖1或圖4至圖7的任一種。 In the touch display panel of the above embodiments, the barrier wall structure 140 is disposed on the first substrate 100, but the invention is not limited thereto. In other embodiments, the barrier wall structure 140 may also be disposed on the second substrate 180. As shown in FIG. 8, the barrier wall structure 140 is disposed on the surface of the electrode layer 186 on the second substrate 180. In the embodiment of FIG. 8 , except that the barrier wall structure 140 is disposed on the second substrate 180 and is different from the previous embodiments, other components (such as the arrangement of the touch spacer and the sensing electrode and the main spacer) Same as or similar to the setting of the secondary spacers, etc.). In addition, the layout of the barrier wall structure 140 disposed on the second substrate 180 may be any of FIG. 1 or FIG. 4 to FIG.
另外，根據另一實施例，如圖9所示，阻隔牆結構140是由第一阻隔牆結構141a以及第二阻隔牆結構141b所構成，第一與第二阻隔牆結構141a,141b分別位於第一基板100以及第二基板180上。類似地，第一與第二阻隔牆結構141a,141b是位於畫素區域110的遮光區130內。特別是，第一阻隔牆結構141a與第二阻隔牆結構141b之間具有第二間隙(G2)，且G1<G2<4G1。換言之，在圖9之實施例中，第二間隙(G2)是第一阻隔牆結構141a表面與第二阻隔牆結構141b表面之間的距離。在圖9之實施例中，每一畫素區域110內的第一阻隔牆結構141a或第二阻隔牆結構141b所佔的面積為畫素區域110的面積的4~35%。另外，第一阻隔牆結構141a與第二阻隔牆結構141b的邊緣與畫素區域110之遮光區130之邊緣相距1.5~5微米的距離。此外，第一阻隔牆結構141a與第二阻隔牆結構141b的頂部寬度小於底部寬度，因此第一阻隔牆結構141a與第二阻隔牆結構141b的側壁與第一基板100之表面的夾角為50 ~90度。再者，第一阻隔牆結構141a與第二阻隔牆結構141b的材料可為透明介電材料或是非透明介電材料，且其介電係數介於1~5。同樣地，第一阻隔牆結構141a與第二阻隔牆結構141b的佈局可以是圖1或圖4至圖7的任一種。 In addition, according to another embodiment, as shown in FIG. 9, the barrier wall structure 140 is composed of a first barrier wall structure 141a and a second barrier wall structure 141b, and the first and second barrier wall structures 141a, 141b are respectively located at A substrate 100 and a second substrate 180. Similarly, the first and second barrier wall structures 141a, 141b are located within the light blocking region 130 of the pixel region 110. In particular, there is a second gap (G 2 ) between the first barrier wall structure 141a and the second barrier wall structure 141b, and G 1 <G 2 <4G 1 . In other words, in the embodiment of Fig. 9, the second gap (G 2 ) is the distance between the surface of the first barrier wall structure 141a and the surface of the second barrier wall structure 141b. In the embodiment of FIG. 9, the area of the first barrier wall structure 141a or the second barrier wall structure 141b in each pixel region 110 occupies 4 to 35% of the area of the pixel region 110. In addition, the edges of the first barrier wall structure 141a and the second barrier wall structure 141b are at a distance of 1.5 to 5 micrometers from the edge of the light shielding region 130 of the pixel region 110. In addition, the top width of the first barrier wall structure 141a and the second barrier wall structure 141b is smaller than the bottom width, so the angle between the sidewalls of the first barrier wall structure 141a and the second barrier wall structure 141b and the surface of the first substrate 100 is 50 ~ 90 degrees. Furthermore, the material of the first barrier wall structure 141a and the second barrier wall structure 141b may be a transparent dielectric material or a non-transparent dielectric material, and the dielectric constant thereof is between 1 and 5. Likewise, the layout of the first barrier wall structure 141a and the second barrier wall structure 141b may be any of FIG. 1 or FIG. 4 to FIG.
值得一提的是，本發明所提出的阻隔牆結構可以適用於各種形式的液晶顯示面板，例如垂直配向式液晶顯示面板、向列式液晶顯示面板、超扭轉向列式液晶顯示面板等等。若將上述之阻隔牆結構應用於垂直配向式液晶顯示面板，那麼此顯示面板內更包括配向圖案，如圖10以及圖11所示。請先參照圖10，在圖10之實施例中，觸控式顯示面板更包括配向突起圖案302，其設置於第二基板180上。在此實施例中，當於第二基板180上設置配向突起圖案302時，較佳的是將阻隔牆結構140設置於第一基板100上。另外，在圖11之實施例中，觸控式顯示面板更包括配向狹縫圖案304，其設置於第一基板100之畫素電極104中。在此實施例中，當於第一基板100之畫素電極104中設置配向狹縫圖案304時，較佳的是將阻隔牆結構140設置於第二基板180上。 It is worth mentioning that the barrier wall structure proposed by the present invention can be applied to various forms of liquid crystal display panels, such as a vertical alignment type liquid crystal display panel, a nematic liquid crystal display panel, a super twisted nematic liquid crystal display panel, and the like. If the above-mentioned barrier wall structure is applied to a vertical alignment type liquid crystal display panel, the display panel further includes an alignment pattern, as shown in FIG. 10 and FIG. Referring to FIG. 10 , in the embodiment of FIG. 10 , the touch display panel further includes an alignment protrusion pattern 302 disposed on the second substrate 180 . In this embodiment, when the alignment protrusion pattern 302 is disposed on the second substrate 180, it is preferable to dispose the barrier wall structure 140 on the first substrate 100. In addition, in the embodiment of FIG. 11 , the touch display panel further includes an alignment slit pattern 304 disposed in the pixel electrode 104 of the first substrate 100 . In this embodiment, when the alignment slit pattern 304 is disposed in the pixel electrode 104 of the first substrate 100, it is preferable to dispose the barrier wall structure 140 on the second substrate 180.
綜合以上所述，本發明因於觸控式顯示面板內設計阻隔牆結構，因此當對觸控式顯示面板進行按壓之觸控操作時，阻隔牆結構可以將觸控式顯示面板之液晶侷限於特定區域，使得液晶擾動程度降低。如此一來，顯示面板的延遲值不易被改變，因而可以改善按壓處的顯示瑕疵(mura)之問題。 In summary, the present invention is designed to block the wall structure in the touch display panel. Therefore, when the touch display panel is pressed, the barrier wall structure can limit the liquid crystal of the touch display panel. The specific area causes the degree of liquid crystal disturbance to decrease. As a result, the delay value of the display panel is not easily changed, so that the problem of the display mura at the pressing portion can be improved.
