Description
本創作關於觸控顯示裝置,特別是關於嵌入式觸控顯示裝置。This creation relates to touch display devices, and more particularly to embedded touch display devices.
嵌入式觸控技術目前主要的發展方向可分為On-Cell及In-Cell兩種技術。On-Cell Touch的技術是將觸控面板的感應裝置(Sensor)製作在薄膜上,然後貼合在最上層的上基板的玻璃上。In-Cell Touch技術則是將觸控元件整合於顯示面板之內,使得顯示面板本身就具備觸控功能,因此不需要與觸控面板貼合或組裝的額外製程。The main development direction of embedded touch technology can be divided into On-Cell and In-Cell technologies. The technology of On-Cell Touch is to make a touch panel sensor on the film and then attach it to the glass of the uppermost upper substrate. The In-Cell Touch technology integrates the touch components into the display panel, so that the display panel itself has a touch function, so there is no need for an additional process of attaching or assembling the touch panel.
而觸控原理則包括光學式、電阻式及電容式等類型。根據光學式觸控原理,透過光學感應器偵測因觸控所致的光學變化,即可得知觸控的位置;根據電阻式觸控原理,分開的上感應電極層及下感應電極層因觸控的壓力而彼此接觸導通而產生電流變化,透過偵測此一電流變化即可得知觸控的位置;根據電容式觸控原理,感應電極層因觸控的靜電感應而產生電壓變化,透過偵測此一電壓變化即可得知觸控的位置。The touch principle includes optical, resistive and capacitive types. According to the optical touch principle, the position of the touch can be known by detecting the optical change caused by the touch through the optical sensor; according to the resistive touch principle, the separated upper sensing electrode layer and the lower sensing electrode layer are separated The touch pressure is in contact with each other to generate a current change. The position of the touch can be known by detecting the change of the current. According to the capacitive touch principle, the sensing electrode layer generates a voltage change due to the electrostatic induction of the touch. The position of the touch can be known by detecting this voltage change.
為追求電子裝置之小型化、元件之整合及製程之便利,嵌入式觸控顯示裝置蔚為發展。然而,這些目標尚存在若干問題必須克服。在嵌入式觸控顯示裝置中,觸控元件由於設置在顯示裝置之內,觸控訊號與顯示訊號容易互相干擾。在採用互電容(mutual-capacitance)感應的情況下,觸控感應層(Rx)與觸控驅動層(Tx)將引發大量雜訊,並增加布局的複雜度,而難以整合觸控元件與顯示裝置。因此,目前亟需一種新的嵌入式觸控顯示裝置,以滿足上述需求,並避免上述問題。In order to pursue the miniaturization of electronic devices, the integration of components, and the convenience of manufacturing processes, embedded touch display devices have been developed. However, there are still several issues that must be overcome in these goals. In the embedded touch display device, since the touch component is disposed in the display device, the touch signal and the display signal easily interfere with each other. In the case of mutual-capacitance sensing, the touch sensing layer (Rx) and the touch driving layer (Tx) will cause a lot of noise and increase the complexity of the layout, and it is difficult to integrate the touch elements and display. Device. Therefore, there is a need for a new embedded touch display device to meet the above needs and to avoid the above problems.

As shown in FIG. 2, the plurality of scan lines 1032 and the plurality of data lines 1033 are substantially vertically staggered, and at least one thin film transistor 1031 and one pixel electrode 1051 are disposed at each staggered point, and the gate of the thin film transistor 1031 is connected to the scan line. 1032. The scan line 1032 can control the switching of the thin film transistor 1031.

The sensing electrode trace 1034 can transmit the capacitive excitation signal to the touch sensing electrode 1052 or receive the touch sensing signal from the touch sensing electrode 1052. Each touch sensing electrode is composed of a transparent mesh surrounded by a plurality of pixel electrodes, and each touch sensing electrode is connected to at least one sensing electrode trace 1034, and the sensing electrode trace 1034 is made of a transparent conductive material of the same layer. The composition is composed of a data line 1033 of the lower thin film transistor layer and/or a conductive metal of the metal sublayer of the scan line 1032. The sensing electrode traces 1034 are preferably metal traces.
請參照圖1、2,公共電極層104包括複數公共電極1041及反射遮蔽電極1042。值得注意的是,各公共電極1041之間具有間隔,然而,在圖1之剖面以外之處,其等可相連或不相連。同理,各畫素電極1051之間具有間隔,然而,在圖1之剖面以外之處,其等可相連或不相連。Referring to FIGS. 1 and 2, the common electrode layer 104 includes a plurality of common electrodes 1041 and reflective shielding electrodes 1042. It is to be noted that there is a space between the common electrodes 1041, however, they may be connected or not connected outside the section of FIG. Similarly, there is a space between the respective pixel electrodes 1051, however, they may be connected or disconnected outside the section of FIG.
在本實施例中,公共電極1041彼此電性連接,故其等處於等電位。公共電極1041及畫素電極1051之間可形成電場,以控制顯示材料層106的顯示材料1061。由於公共電極1041及反射遮蔽電極1042處於同一層,兩者較佳可在同一製程步驟中形成。具體而言,兩者可採用同一透明導電材料,例如:ITO、ZnO、IZO、GZO、導電高分子、奈米碳管、石墨烯或厚度小於50nm之銀膜。兩者亦可透過同一光罩形成。據此,製程可被簡化。然而,在其他實施例中,公共電極1041及反射遮蔽電極1051可在不同製程步驟中形成,亦可採用不同透明導電材料或透過不同光罩形成。In the present embodiment, the common electrodes 1041 are electrically connected to each other, so that they are at the same potential. An electric field may be formed between the common electrode 1041 and the pixel electrode 1051 to control the display material 1061 of the display material layer 106. Since the common electrode 1041 and the reflective shielding electrode 1042 are in the same layer, they are preferably formed in the same process step. Specifically, the same transparent conductive material can be used, for example, ITO, ZnO, IZO, GZO, conductive polymer, carbon nanotube, graphene or a silver film having a thickness of less than 50 nm. Both can also be formed through the same mask. Accordingly, the process can be simplified. However, in other embodiments, the common electrode 1041 and the reflective shielding electrode 1051 may be formed in different process steps, or may be formed by using different transparent conductive materials or through different masks.
反射遮蔽電極1042的位置對應於觸控感應電極1052的位置。具體而言,反射遮蔽電極1042位在觸控感應電極1052的下方,且觸控感應電極1052的至少一部份重疊於反射遮蔽電極1042的至少一部份。由於觸控感應電極1052甚為敏感,若有線路(例如:資料線1033)設置在其下方,則其容易受到干擾。因此,在觸控感應電極1052及線路之間設置反射遮蔽電極1042,反射遮蔽電極1042可產生屏蔽效應,而避免下方線路干擾觸控感應電極1052。在本實施例中,公共電極1041及反射遮蔽電極1042並不電性連接,因此可賦予兩者不同訊號,例如:賦予公共電極1041直流訊號,而賦予反射遮蔽電極1042交流訊號。The position of the reflective shielding electrode 1042 corresponds to the position of the touch sensing electrode 1052. Specifically, the reflective shielding electrode 1042 is located below the touch sensing electrode 1052, and at least a portion of the touch sensing electrode 1052 is overlapped with at least a portion of the reflective shielding electrode 1042. Since the touch sensing electrode 1052 is very sensitive, if a line (for example, the data line 1033) is disposed below it, it is susceptible to interference. Therefore, a reflective shielding electrode 1042 is disposed between the touch sensing electrode 1052 and the line, and the reflective shielding electrode 1042 can generate a shielding effect to prevent the lower line from interfering with the touch sensing electrode 1052. In this embodiment, the common electrode 1041 and the reflective shielding electrode 1042 are not electrically connected, so that different signals can be given to each other, for example, a direct current signal is applied to the common electrode 1041, and an alternating current signal is applied to the reflective shielding electrode 1042.
電極整合層105包括複數畫素電極1051及複數觸控感應電極1052。如圖1所示,畫素電極1051及觸控感應電極1052實質上被整合於同一層。具體而言,畫素電極1051的至少一部分及觸控感應電極1052的至少一部分處於同一平面。據此,觸控元件及顯示裝置可被內嵌式地整合,而觸控顯示裝置亦可被小型化。由於畫素電極1051及觸控感應電極1052處於同一層,兩者較佳可在同一製程步驟中形成。具體而言,兩者可採用同一透明導電材料,例如:ITO、ZnO、IZO、GZO、導電高分子、奈米碳管、石墨烯或厚度小於50nm之銀膜。兩者亦可透過同一光罩形成。據此,製程可被簡化。然而,在其他實施例中,畫素電極1051及觸控感應電極1052可在不同製程步驟中形成,亦可採用不同透明導電材料或透過不同光罩形成。The electrode integration layer 105 includes a plurality of pixel electrodes 1051 and a plurality of touch sensing electrodes 1052. As shown in FIG. 1, the pixel electrode 1051 and the touch sensing electrode 1052 are substantially integrated in the same layer. Specifically, at least a portion of the pixel electrode 1051 and at least a portion of the touch sensing electrode 1052 are in the same plane. Accordingly, the touch element and the display device can be integrated in-line, and the touch display device can also be miniaturized. Since the pixel electrode 1051 and the touch sensing electrode 1052 are in the same layer, they are preferably formed in the same process step. Specifically, the same transparent conductive material can be used, for example, ITO, ZnO, IZO, GZO, conductive polymer, carbon nanotube, graphene or a silver film having a thickness of less than 50 nm. Both can also be formed through the same mask. Accordingly, the process can be simplified. However, in other embodiments, the pixel electrode 1051 and the touch sensing electrode 1052 may be formed in different process steps, or may be formed by using different transparent conductive materials or through different masks.
薄膜電晶體層103、公共電極層104及電極整合層105之間可設置絕緣層,以支撐各層,並使各層電性絕緣。若各層需要電性連接,則可透過通孔為之。An insulating layer may be disposed between the thin film transistor layer 103, the common electrode layer 104, and the electrode integration layer 105 to support the layers and electrically insulate the layers. If the layers need to be electrically connected, they can pass through the through holes.
如圖2所示,各畫素200是由三子畫素201、202、203所組成。子畫素201、202、203可分別顯示紅、綠、藍,但不限於此。在本實施例中,畫素電極1051較佳位在子畫素的中央,而觸控感應電極1052較佳位在子畫素的周邊,而圍繞畫素電極1051。如此可維持畫素200的開口率及透光率。在其他實施例中,觸控感應電極1052可位在子畫素的一邊或數邊,亦可被黑矩陣層108覆蓋。在如此配置下,複數觸控感應電極1052整體呈現網格狀,且每一觸控感應電極1052可含蓋複數個畫素電極1051周遭範圍,例如一觸控感應電極1052含蓋500個畫素電極1051周遭。電極走線1034由同層之透明導電材料構成,也可由位在反射遮蔽電極1042下方金屬層之導電金屬構成,以降低阻抗並免於干擾其他感應電極1052。As shown in FIG. 2, each pixel 200 is composed of three sub-pixels 201, 202, and 203. The sub-pixels 201, 202, and 203 may display red, green, and blue, respectively, but are not limited thereto. In this embodiment, the pixel electrode 1051 is preferably located at the center of the sub-pixel, and the touch sensing electrode 1052 is preferably located at the periphery of the sub-pixel and surrounds the pixel electrode 1051. Thus, the aperture ratio and light transmittance of the pixel 200 can be maintained. In other embodiments, the touch sensing electrode 1052 can be located on one side or several sides of the sub-pixel, or can be covered by the black matrix layer 108. In this configuration, the plurality of touch sensing electrodes 1052 are generally grid-shaped, and each of the touch sensing electrodes 1052 can cover a plurality of pixel electrodes 1051, for example, a touch sensing electrode 1052 includes 500 pixels. The electrode 1051 is surrounded. The electrode trace 1034 is composed of a transparent conductive material of the same layer, or may be composed of a conductive metal located under the metal layer under the reflective shield electrode 1042 to reduce the impedance and avoid interference with the other sensing electrodes 1052.
本創作的嵌入式觸控顯示裝置,採用的感應原理是自電容(self-capacitance)感應。自電容(C)定義為使一單獨導體增加一單位電壓(V)所需的電荷量(Q)。互電容感應需要雙層觸控感應電極,在其間建立電容,始可進行觸控感應。相較於互電容感應,自電容感應只需要單層觸控感應電極,以其自電容,即可進行觸控感應,且其感應靈敏性與訊號雜訊比皆優於互電容方式,特別適用於內嵌式觸控裝置。因此,在圖1中,觸控感應電極1052處於同一平面,且只有觸控感應電極1052參與一觸控感應。在圖2中,觸控感應電極1052自感應電極走線1034接收電容激勵訊號,亦自感應電極走線1034傳送觸控感應訊號。觸控感應電極1052透過自電容感應將電容激勵訊號轉換成觸控感應訊號,例如:當人體接近或觸碰觸控感應電極1052時,觸控感應訊號會因人體的靜電感應而大幅衰減或增強。從而,觸控感應控制電路520可透過偵測觸控感應訊號判斷觸控感應電極1052是否被接近或觸碰。The embedded touch display device of the present invention adopts a sensing principle that is self-capacitance sensing. The self-capacitance (C) is defined as the amount of charge (Q) required to increase a single conductor by one unit voltage (V). Mutual capacitance sensing requires a double-layer touch sensing electrode, and a capacitance can be established between them to enable touch sensing. Compared with mutual capacitance sensing, self-capacitance sensing only requires a single-layer touch sensing electrode, and its self-capacitance can be used for touch sensing, and its sensing sensitivity and signal noise ratio are superior to mutual capacitance mode, and is particularly suitable. For in-cell touch devices. Therefore, in FIG. 1 , the touch sensing electrodes 1052 are in the same plane, and only the touch sensing electrodes 1052 participate in a touch sensing. In FIG. 2, the touch sensing electrode 1052 receives the capacitive excitation signal from the sensing electrode trace 1034, and also transmits the touch sensing signal from the sensing electrode trace 1034. The touch sensing electrode 1052 converts the capacitive excitation signal into a touch sensing signal through self-capacitance sensing. For example, when the human body approaches or touches the touch sensing electrode 1052, the touch sensing signal is greatly attenuated or enhanced by the static induction of the human body. Therefore, the touch sensing control circuit 520 can determine whether the touch sensing electrode 1052 is approached or touched by detecting the touch sensing signal.
回到圖1,顯示材料層106包括顯示材料1061。顯示材料1061可具有極性。在本實施例中,顯示材料1061為液晶。Returning to Figure 1, the display material layer 106 includes display material 1061. Display material 1061 can have a polarity. In the present embodiment, the display material 1061 is a liquid crystal.
本實施例採用的顯示技術是邊緣電場轉換(fringe field switching,FFS)顯示技術。如圖1所示,畫素電極1051平行於公共電極1041,兩者上下交錯排列,亦即,兩相鄰畫素電極1051之間的間隔下方具有公共電極1041,或兩相鄰公共電極1041之間的間隔上方具有畫素電極1051。The display technology used in this embodiment is a fringe field switching (FFS) display technology. As shown in FIG. 1, the pixel electrode 1051 is parallel to the common electrode 1041, and the two are staggered up and down, that is, the common electrode 1041 or the two adjacent common electrodes 1041 are disposed under the interval between two adjacent pixel electrodes 1051.

圖3A為本創作第一實施例的畫素電極1051及公共電場1041之間的電場圖。如圖3A所示,當畫素電極1051及公共電極1041被施加電壓時,兩者之間會形成電場。舉例而言,若以畫素電極1051作為正電極,而以公共電極1041作為負電極,則電場自畫素電極1051指向公共電極1041。其中,自畫素電極1051的上表面指向公共電極1041的上表面的電場,會影響顯示材料1061。在圖1中,顯示材料1061會根據電場而旋轉至特定方向。根據顯示材料1061的旋轉方向,偏振光可能通過、部分通過或不通過上偏光層110。據此,畫素的灰階可被決定。FIG. 3A is an electric field diagram between the pixel electrode 1051 and the common electric field 1041 of the first embodiment of the present invention. As shown in FIG. 3A, when a voltage is applied to the pixel electrode 1051 and the common electrode 1041, an electric field is formed therebetween. For example, if the pixel electrode 1051 is used as the positive electrode and the common electrode 1041 is used as the negative electrode, the electric field is directed from the pixel electrode 1051 to the common electrode 1041. The electric field of the upper surface of the self-picking electrode 1051 directed to the upper surface of the common electrode 1041 affects the display material 1061. In Figure 1, display material 1061 is rotated to a particular direction depending on the electric field. Depending on the direction of rotation of the display material 1061, the polarized light may pass, partially pass or not pass through the upper polarizing layer 110. According to this, the gray scale of the pixels can be determined.

黑矩陣層108包括不透明區域1081。不透明區域1081可以複數黑色線條所構成。不透明區域1081較佳是位在薄膜電晶體1031與資料線及掃描線的上方,更佳是又含蓋觸控感應電極1052的上方。如此可避免環境光直射薄膜電晶體1031或觸控感應電極1052,而可維護此等元件的特性,進而可維持觸控顯示裝置的顯示品質。The black matrix layer 108 includes an opaque region 1081.

The opaque region 1081 is preferably located above the thin film transistor 1031 and the data line and the scan line, and more preferably covers the top of the touch sensing electrode 1052. In this way, the ambient light direct-transmissive film transistor 1031 or the touch sensing electrode 1052 can be avoided, and the characteristics of the components can be maintained, thereby maintaining the display quality of the touch display device.
圖4為本創作第一實施例的彩色濾光層及黑矩陣層的上視圖。如圖4所示,不透明區域1081圍繞彩色濾光片1071、1072、1073,而呈現網格狀。在製程上,黑矩陣層108可用於定義彩色濾光片1071、1072、1073的區域。在其他實施例中,黑矩陣層108可被省略。在此情況下,配合透明基板、透明電晶體、透明線路等透明元件,透明顯示器可被實現。4 is a top view of the color filter layer and the black matrix layer of the first embodiment of the present invention.

In the process, the black matrix layer 108 can be used to define regions of the color filters 1071, 1072, 1073. In other embodiments, the black matrix layer 108 can be omitted. In this case, a transparent display can be realized by a transparent member such as a transparent substrate, a transparent transistor, or a transparent wiring.
圖5為本創作第一實施例的觸控顯示裝置的電路圖。如圖5所示,嵌入式觸控顯示裝置100包括一閘極驅動電路511、一源極驅動電路512及一觸控感應控制電路520。閘極驅動電路511及源極驅動電路512屬於一顯示控制電路510。閘極驅動電路511自掃描線1032控制薄膜電晶體1031的閘極,源極驅動電路512自資料線1033傳送訊號至薄膜電晶體1031,以對於畫素電極進行充放電。觸控感應控制電路520包括自電容偵測電路600及複數開關521。自電容偵測電路600透過感應電極走線1034,將電容激勵訊號傳送至觸控感應電極1052,然後自觸控感應電極1052接收觸控感應訊號。觸控感應控制電路520透過開關521選擇將電容激勵訊號傳送至哪個觸控感應電極1052或自哪個觸控感應電極1052接收觸控感應訊號。FIG. 5 is a circuit diagram of the touch display device of the first embodiment of the present invention. As shown in FIG. 5 , the embedded touch display device 100 includes a gate driving circuit 511 , a source driving circuit 512 , and a touch sensing control circuit 520 . The gate driving circuit 511 and the source driving circuit 512 belong to a display control circuit 510. The gate driving circuit 511 controls the gate of the thin film transistor 1031 from the scanning line 1032, and the source driving circuit 512 transmits a signal from the data line 1033 to the thin film transistor 1031 to charge and discharge the pixel electrode. The touch sensing control circuit 520 includes a self-capacitance detecting circuit 600 and a plurality of switches 521. The self-capacitance detecting circuit 600 transmits the capacitive excitation signal to the touch sensing electrode 1052 through the sensing electrode trace 1034, and then receives the touch sensing signal from the touch sensing electrode 1052. The touch sensing control circuit 520 selects which touch sensing electrode 1052 to transmit the capacitive excitation signal to or receives from the touch sensing electrode 1052 through the switch 521.
圖6A為本創作第一實施例的第一例的自電容偵測電路的電路圖。如圖6A所示,自電容偵測電路600包括一交流訊號源611、二放大器621、622及一電容讀取電路632。此外,二節點X1、X2亦被標示。6A is a circuit diagram of a self-capacitance detecting circuit of a first example of the first embodiment of the present invention. As shown in FIG. 6A, the self-capacitance detecting circuit 600 includes an AC signal source 611, two amplifiers 621 and 622, and a capacitor reading circuit 632. In addition, the two nodes X1, X2 are also marked.
放大器621的增益大於0,其輸入端連接至交流訊號源611,其輸出端則連接至節點X1。放大器621及交流訊號源611構成一電容激勵驅動電路631,以自節點X1輸出一電容激勵訊號至觸控感應電極1052。從而,電容激勵訊號為一交流訊號。電容激勵訊號可被依序或隨機輸出至複數觸控感應電極1052。具體而言,為了避免電容激勵訊號與顯示訊號互相干擾,電容激勵訊號可依序或隨機與顯示訊號錯開,例如:當顯示訊號依序地掃描時,電容激勵訊號亦依序地掃描,而透過延遲錯開;或者,當顯示訊號隨機地掃描時,電容激勵訊號亦隨機地掃描,而在大部分時間錯開。The gain of amplifier 621 is greater than zero, its input is connected to AC signal source 611, and its output is connected to node X1. The amplifier 621 and the AC signal source 611 form a capacitive excitation driving circuit 631 for outputting a capacitive excitation signal from the node X1 to the touch sensing electrode 1052. Thus, the capacitive excitation signal is an alternating current signal. The capacitive excitation signal can be sequentially or randomly outputted to the plurality of touch sensing electrodes 1052. Specifically, in order to prevent the capacitive excitation signal and the display signal from interfering with each other, the capacitive excitation signal may be staggered sequentially or randomly with the display signal. For example, when the display signal is sequentially scanned, the capacitive excitation signal is also sequentially scanned and transmitted through The delay is staggered; or, when the display signal is randomly scanned, the capacitive excitation signals are also randomly scanned and staggered most of the time.
放大器622的增益大於0,其輸入端連接至節點X1,其輸出端則連接至節點X2。放大器622在輸入電容激勵訊號或觸控感應訊號後,自節點X2輸出一反射遮蔽訊號至反射遮蔽電極1042。因此,反射遮蔽訊號的相位可相同於電容激勵訊號的相位或觸控感應訊號的相位。根據開關521的切換,反射遮蔽訊號的相位可在第一時間相同於電容激勵訊號的相位,而在第二時間相同於觸控感應訊號的相位。由於電容激勵訊號或觸控感應訊號與反射遮蔽訊號具有同一相位,感應電極走線1034及反射遮蔽電極之間的電容耦合效應即被降低,進而在感應電極走線1034傳送的電容激勵訊號、觸控感應訊號可不被干擾,而被維持。The gain of amplifier 622 is greater than zero, its input is connected to node X1, and its output is connected to node X2. After inputting the capacitive excitation signal or the touch sensing signal, the amplifier 622 outputs a reflection shielding signal from the node X2 to the reflective shielding electrode 1042. Therefore, the phase of the reflected masking signal can be the same as the phase of the capacitive excitation signal or the phase of the touch sensing signal. According to the switching of the switch 521, the phase of the reflected masking signal can be the same as the phase of the capacitive excitation signal at the first time and the same as the phase of the touch sensing signal at the second time. Since the capacitive excitation signal or the touch sensing signal has the same phase as the reflected shielding signal, the capacitive coupling effect between the sensing electrode trace 1034 and the reflective shielding electrode is reduced, and the capacitive excitation signal, touch transmitted on the sensing electrode trace 1034 The control signal can be maintained without being disturbed.
電容讀取電路632連接至節點X1,以讀取觸控感應訊號。在一觸控過程中,電容激勵訊號自電容激勵驅動電路631輸出,透過感應電極走線1034前往觸控感應電極1052,被觸控感應電極1052轉換成觸控感應訊號,再透過感應電極走線1034回到電容讀取電路632。電容讀取電路632可比較電容激勵訊號及觸控感應訊號的差異,進而判斷觸控感應電極1052是否被觸控。The capacitance reading circuit 632 is connected to the node X1 to read the touch sensing signal. In a touch process, the capacitive excitation signal is output from the capacitive excitation driving circuit 631, and is sent to the touch sensing electrode 1052 through the sensing electrode trace 1034, converted into a touch sensing signal by the touch sensing electrode 1052, and then passed through the sensing electrode. 1034 returns to capacitor reading circuit 632. The capacitance reading circuit 632 compares the difference between the capacitive excitation signal and the touch sensing signal to determine whether the touch sensing electrode 1052 is touched.
圖6B為本創作第一實施例的第二例的自電容偵測電路的電路圖。如圖6B所示,在本例中,自電容偵測電路600包括一交流訊號源611、二放大器621、622及一電容讀取電路632。本例不同於第一例之處在於:放大器622的輸入端不連接至節點X1,而連接至交流訊號源611。在此配置下,反射遮蔽訊號的相位亦可相同於電容激勵訊號的相位或觸控感應訊號的相位,使得電容激勵訊號、觸控感應訊號可不被干擾,而被維持。6B is a circuit diagram of a self-capacitance detecting circuit of a second example of the first embodiment of the present invention. As shown in FIG. 6B, in this example, the self-capacitance detecting circuit 600 includes an AC signal source 611, two amplifiers 621 and 622, and a capacitor reading circuit 632. This example differs from the first example in that the input of the amplifier 622 is not connected to the node X1 but to the AC signal source 611. In this configuration, the phase of the reflected masking signal can be the same as the phase of the capacitive excitation signal or the phase of the touch sensing signal, so that the capacitive excitation signal and the touch sensing signal can be maintained without being disturbed.
第二實施例Second embodiment
圖7為本創作第二實施例的具有透明網格觸控電極之觸控顯示裝置的剖面圖。如圖7所示,嵌入式觸控顯示裝置100依序包括一下偏光層101、一下基板102、一薄膜電晶體層103、一公共電極層104、一電極整合層105、一顯示材料層106、一彩色濾光層107、一黑矩陣層108、一上基板109及一上偏光層110。在本實施例中,除了公共電極層104之外,其他元件的材料、結構、配置、功能均如同第一實施例者。7 is a cross-sectional view of a touch display device having a transparent grid touch electrode according to a second embodiment of the present invention. As shown in FIG. 7 , the embedded touch display device 100 sequentially includes a lower polarizing layer 101 , a lower substrate 102 , a thin film transistor layer 103 , a common electrode layer 104 , an electrode integration layer 105 , a display material layer 106 , A color filter layer 107, a black matrix layer 108, an upper substrate 109, and an upper polarizing layer 110. In the present embodiment, the materials, structures, configurations, and functions of the other elements are the same as those of the first embodiment except for the common electrode layer 104.
如圖7所示,在本實施例中,公共電極層104僅包括公共電極1041,而不具有反射遮蔽電極。以另一觀點而言,在第一實施例中的反射遮蔽電極1042,在本實施例中被取代為公共電極1041。在本實施例中,公共電極1041較佳為一整片。對於畫素電極1051而言,若公共電極1041為一整片,則兩者之間的電容較大,如此有助於顯示。對於觸控感應電極1052而言,若公共電極1041為一整片,則其可產生屏蔽效應,而避免下方線路干擾觸控感應電極1052。As shown in FIG. 7, in the present embodiment, the common electrode layer 104 includes only the common electrode 1041 without a reflective shielding electrode. From another point of view, the reflective shield electrode 1042 in the first embodiment is replaced with the common electrode 1041 in this embodiment. In the present embodiment, the common electrode 1041 is preferably a single piece. For the pixel electrode 1051, if the common electrode 1041 is a single piece, the capacitance between the two is large, which is helpful for display. For the touch sensing electrode 1052, if the common electrode 1041 is a whole piece, it can produce a shielding effect, and avoid the lower line from interfering with the touch sensing electrode 1052.
本實施例採用的顯示技術是邊緣電場轉換顯示技術。如圖7所示,相較於第一實施例,本實施例的公共電極1041為一整片。畫素電極1051平行於公共電極1041。兩相鄰畫素電極1051之間具有間隔。圖3B為本創作第二實施例的畫素電極1051及公共電極1041之間的電場圖。如圖3B所示,第二實施例的電場形狀相似於第一實施例的電場形狀。The display technology used in this embodiment is a fringe electric field conversion display technology. As shown in FIG. 7, the common electrode 1041 of the present embodiment is a whole piece as compared with the first embodiment. The pixel electrode 1051 is parallel to the common electrode 1041. There is a space between two adjacent pixel electrodes 1051. FIG. 3B is an electric field diagram between the pixel electrode 1051 and the common electrode 1041 of the second embodiment of the present invention. As shown in Fig. 3B, the electric field shape of the second embodiment is similar to that of the first embodiment.
第二實施例的電路,可採用第一實施例的電路500,在此不再贅述。For the circuit of the second embodiment, the circuit 500 of the first embodiment can be used, and details are not described herein again.
第三實施例Third embodiment
圖8為本創作第三實施例的觸控顯示裝置的剖面圖。如圖8所示,嵌入式觸控顯示裝置100依序包括一下偏光層101、一下基板102、一薄膜電晶體層103、一電極整合層105、一顯示材料層106、一彩色濾光層107、一黑矩陣層108、一上基板109及一上偏光層110。相較於第一實施例,本實施例不具有公共電極層,且在本實施例中,除了整合電極層105之外,其他元件的材料、結構、配置、功能均如同第一實施例者。FIG. 8 is a cross-sectional view showing a touch display device according to a third embodiment of the present invention. As shown in FIG. 8 , the embedded touch display device 100 sequentially includes a lower polarizing layer 101 , a lower substrate 102 , a thin film transistor layer 103 , an electrode integration layer 105 , a display material layer 106 , and a color filter layer 107 . A black matrix layer 108, an upper substrate 109 and an upper polarizing layer 110. Compared with the first embodiment, the present embodiment does not have a common electrode layer, and in the present embodiment, the materials, structures, configurations, and functions of other elements are the same as those of the first embodiment except for integrating the electrode layer 105.
在本實施例中,公共電極1041被整合於電極整合層105。如圖8所示,公共電極1041、畫素電極1051及觸控電極1052均在同一層。具體而言,公共電極1041、畫素電極1051及觸控電極105各至少一部分處於同一平面。據此,觸控元件及顯示裝置可被內嵌式地整合,而觸控顯示裝置亦可被小型化。由於公共電極1041、畫素電極1051及觸控電極1052處於同一層,三者較佳可在同一製程步驟中形成,例如:採用同一透明導電材料,或透過同一光罩形成。據此,製程可被簡化。In the present embodiment, the common electrode 1041 is integrated in the electrode integration layer 105. As shown in FIG. 8, the common electrode 1041, the pixel electrode 1051, and the touch electrode 1052 are all in the same layer. Specifically, at least a part of the common electrode 1041, the pixel electrode 1051, and the touch electrode 105 are in the same plane. Accordingly, the touch element and the display device can be integrated in-line, and the touch display device can also be miniaturized. Since the common electrode 1041, the pixel electrode 1051 and the touch electrode 1052 are in the same layer, the three are preferably formed in the same process step, for example, using the same transparent conductive material or formed through the same mask. Accordingly, the process can be simplified.
本實施例採用的顯示技術是平面轉換(in-plane switching,IPS)顯示技術。如圖8所示,畫素電極1051及公共電極1041處於同一平面並交錯排列,亦即,兩相鄰畫素電極1051之間的間隔具有公共電極1041,或兩相鄰公共電極1041之間的間隔具有畫素電極1051。The display technology used in this embodiment is an in-plane switching (IPS) display technology. As shown in FIG. 8, the pixel electrode 1051 and the common electrode 1041 are in the same plane and are staggered, that is, the interval between two adjacent pixel electrodes 1051 has a common electrode 1041 or between two adjacent common electrodes 1041. The spacer has a pixel electrode 1051.
圖3C為本創作第一實施例的畫素電極及公共電場之間的電場圖。如圖3C所示,當畫素電極1051及公共電極1041被施加電壓時,兩者之間會形成電場。舉例而言,若以畫素電極1051作為正電極,而以公共電極1041作為負電極,則電場自畫素電極1051指向公共電極1041。其中,自畫素電極1051的上表面指向公共電極1041的上表面的電場,會影響顯示材料1061。在圖8中,顯示材料1061會根據電場而旋轉至特定方向。根據顯示材料1061的旋轉方向,偏振光可能通過、部分通過或不通過上偏光層110。據此,畫素的灰階可被決定。Fig. 3C is an electric field diagram between the pixel electrode and the common electric field of the first embodiment of the creation. As shown in FIG. 3C, when a voltage is applied to the pixel electrode 1051 and the common electrode 1041, an electric field is formed therebetween. For example, if the pixel electrode 1051 is used as the positive electrode and the common electrode 1041 is used as the negative electrode, the electric field is directed from the pixel electrode 1051 to the common electrode 1041. The electric field of the upper surface of the self-picking electrode 1051 directed to the upper surface of the common electrode 1041 affects the display material 1061. In Figure 8, display material 1061 is rotated to a particular direction depending on the electric field. Depending on the direction of rotation of the display material 1061, the polarized light may pass, partially pass or not pass through the upper polarizing layer 110. According to this, the gray scale of the pixels can be determined.
第三實施例的電路,可採用第一實施例的電路500,在此不再贅述。For the circuit of the third embodiment, the circuit 500 of the first embodiment can be used, and details are not described herein again.
綜上所述,本創作提供電極整合層,將畫素電極及觸控電極整合於同一層,使得觸控元件及顯示裝置在結構上及製程上可被整合,進而達到觸控顯示裝置的小型化及製程的簡化。此外,本創作採用自電容感應,以降低線路之間彼此干擾。在某些實施例中,本創作考量到觸控感應電極的敏感性,透過設置反射遮蔽電極及賦予其特定訊號,以避免其他元件干擾觸控感應電極。據此,嵌入式觸控顯示器的雜訊問題獲得改善。In summary, the present invention provides an electrode integration layer that integrates the pixel electrodes and the touch electrodes on the same layer, so that the touch elements and the display device can be integrated in the structure and the process, thereby achieving a small size of the touch display device.
