Description
本發明係與有機發光二極體有關，特別係指一種有機發光二極體觸控面板。 The invention relates to an organic light emitting diode, in particular to an organic light emitting diode touch panel.
目前有機發光二極體的出光方式大致可分為向上發光、向下發光及全穿透發光，當有機發光二極體製作成觸控面板時，依其感測方式的不同可分為電阻式觸控面板、電容式觸控面板、光學式觸控面板等，其中由於電容式觸控面板的反應時間快，耐用性佳，因此目前業界的各種電子產品大部份皆採用電容式觸控面板。 At present, the light-emitting mode of the organic light-emitting diode can be roughly divided into an upward light-emitting, a downward-lighting, and a full-light-emitting light. When the organic light-emitting diode is made into a touch panel, the resistive touch can be classified according to the different sensing modes. Control panels, capacitive touch panels, optical touch panels, etc., because capacitive touch panels have fast response times and good durability, most of the current electronic products in the industry use capacitive touch panels.
當有機發光二極體應用於電容式觸控面板而需附加觸控結構時，可以透過有機發光二極體既有的陽極及陰極作為觸控電極，或是額外增加觸控線路的方式來達成；當利用有機發光二極體上的陽極及陰極作為觸控電極時，雖然可以節省製作成本且在整體厚度上也可達到簡薄的效果，但是在驅動端就必需分時驅動有機發光二極體的顯示與觸控兩個時段；然而若是透過額外增加觸控線路的方式其優點是觸控線路與有機發光二極體的驅動線路是分開驅動，因此在驅動端沒有分時驅動的困擾，並且整體在驅動的完整性及時序上比較容易掌握；但其缺點則是必需考量有機發光二極體在製程順序與結構上是否有足夠的空間。 When the OLED is applied to a capacitive touch panel and requires a touch structure, the anode and cathode of the OLED can be used as a touch electrode or an additional touch line can be added. When the anode and the cathode on the organic light-emitting diode are used as the touch electrode, although the manufacturing cost can be saved and the overall thickness can be achieved, the organic light-emitting diode must be driven in a time-division manner at the driving end. The display and touch of the body are two periods; however, if the method of additionally adding the touch line is that the touch line is separately driven from the driving line of the organic light emitting diode, there is no trouble with the time-division driving at the driving end. And the whole is relatively easy to grasp the integrity and timing of the driver; but its shortcoming is that it is necessary to consider whether there is enough space in the process sequence and structure of the organic light-emitting diode.

請參閱圖4、圖5，說明本發明第一實施例之剖視示意圖及平面示意圖，如圖所示，本發明第一實施例之有機發光二極體觸控面板包括：基板60，可為透明材質；陽極層61，可為透明材質，以間隔排列方式設在基板60上方，且各陽極層61之間搭接以透明材質或半透明材質製成之絕緣層(PI)62，絕緣層(PI)62上方設置以透明材質或半透明材質製成之隔離柱(RIB)63；於本實施例中，陽極層61的材質可以是TCO(Transparent conductive oxide)，如ITO、IZO、ZNO、SnO2，其中以ITO為最佳材質；有機發光層64，塗佈在陽極層61及隔離柱(RIB)63的表面；金屬陰極層65，塗佈位於有機發光層64的表面；於本實施例中，金屬陰極層65的材質可以是金、銀、鋁，其 中以鋁為最佳材質；觸控電極層66，塗佈位於隔離柱(RIB)63上方之有機發光層64的表面，且觸控電極層66設計成沿著隔離柱(RIB)63的走向形成單一X軸方向；蓋板67，封裝於基板60，蓋板67下方係設置吸水材670，藉由吸水材670吸附滲透至蓋板67內部的水氣，避免有機發光層64造成氧化現象。 Referring to FIG. 4 and FIG. 5, a cross-sectional view and a plan view of a first embodiment of the present invention are illustrated. As shown in the figure, the organic light emitting diode touch panel of the first embodiment of the present invention includes: a substrate 60, which may be The transparent material; the anode layer 61, which may be a transparent material, is disposed above the substrate 60 in a spaced arrangement, and an insulating layer (PI) 62 made of a transparent material or a translucent material is overlapped between the anode layers 61, and the insulating layer A spacer (RIB) 63 made of a transparent material or a translucent material is disposed above the (PI) 62. In this embodiment, the material of the anode layer 61 may be TCO (Transparent Conductive Oxide), such as ITO, IZO, ZNO, SnO 2 , wherein ITO is the best material; the organic light-emitting layer 64 is coated on the surface of the anode layer 61 and the spacer (RIB) 63; the metal cathode layer 65 is coated on the surface of the organic light-emitting layer 64; For example, the material of the metal cathode layer 65 may be gold, silver or aluminum, wherein aluminum is the best material; the touch electrode layer 66 is coated on the surface of the organic light-emitting layer 64 above the spacer (RIB) 63, and The touch electrode layer 66 is designed to form along the direction of the spacer (RIB) 63 An X-axis direction; cap plate 67, on the package substrate 60, the cover plate 67 disposed below the water-absorbing material lines 670, 670 by the water-absorbing material penetrates into the interior of the adsorbed water vapor cap plate 67, an organic luminescent layer 64 to avoid oxidation phenomena caused.
在第一實施例中，本發明採用金屬材料對有機發光二極體進行整面濺鍍，使金屬材料同時塗佈在有機發光層64及隔離柱(RIB)63的表面，其中塗佈在有機發光層64表面的金屬材料作為金屬陰極層65，塗佈在隔離柱(RIB)63表面的金屬材料作為觸控電極層66，且金屬材料在濺鍍的過程係藉由隔離柱(RIB)63斷開金屬陰極層65避免形成短路；換言之，本實施例之觸控電極層66的形成是與金屬陰極層65在同一道製程中完成，而不需要額外的製程，當金屬材料在整面濺鍍後，即同時在有機發光層64的表面形成金屬陰極層65，在隔離柱(RIB)63的表面形成觸控電極層66。 In the first embodiment, the present invention uses a metal material to perform a full-surface sputtering of the organic light-emitting diode, so that the metal material is simultaneously coated on the surface of the organic light-emitting layer 64 and the spacer (RIB) 63, wherein the organic light-emitting layer is coated on the organic The metal material on the surface of the light-emitting layer 64 is used as the metal cathode layer 65, the metal material coated on the surface of the spacer (RIB) 63 is used as the touch electrode layer 66, and the metal material is sputtered by a spacer (RIB) 63. The metal cathode layer 65 is disconnected to avoid short circuit formation; in other words, the formation of the touch electrode layer 66 of the present embodiment is completed in the same process as the metal cathode layer 65, without requiring an additional process, when the metal material is splashed over the entire surface. After the plating, the metal cathode layer 65 is simultaneously formed on the surface of the organic light-emitting layer 64, and the touch electrode layer 66 is formed on the surface of the spacer (RIB) 63.
據此，本實施例將隔離柱(RIB)63上的觸控電極層66作為觸控電極使用，同時採用自容式電容偵測的方式對觸控電極層66進行觸控行為的操作，如圖5所示，觸控電極層66可設計成沿著隔離柱(RIB)63的走向形成單一X軸方向，並以此方式，透過每一條觸控電極層66輸出的順序辨識手指對觸控電極層66進行Y軸方向的手勢滑動，例如手勢滑動的方向是由上至下，或是由下至上。 Accordingly, in this embodiment, the touch electrode layer 66 on the isolation column (RIB) 63 is used as a touch electrode, and the touch operation is performed on the touch electrode layer 66 by using a self-capacitive capacitance detection method, such as As shown in FIG. 5, the touch electrode layer 66 can be designed to form a single X-axis direction along the direction of the spacer (RIB) 63, and in this way, the finger-to-touch is recognized through the order of output of each touch electrode layer 66. The electrode layer 66 performs a gesture sliding in the Y-axis direction, for example, the direction in which the gesture slides is from top to bottom, or from bottom to top.
再者，本實施例除了可單獨對每一條觸控電極層66進行觸控 驅動外，亦可先串接複數條觸控電極層66後形成一組觸控結構68，再對各組觸控結構68進行觸控驅動，且各組觸控結構68串接複數條觸控電極層66的串接寬度係可依據使用者手指大小而定，例如串接寬度可為1毫米、2毫米、3毫米、4毫米、5毫米、6毫米，其中最佳的串接寬度值為4毫米~5毫米。 Furthermore, in this embodiment, in addition to individually touching each touch electrode layer 66 In addition, a plurality of touch electrodes 66 are connected in series to form a set of touch structures 68, and then touch driving is performed on each group of touch structures 68, and each group of touch structures 68 is connected in series with a plurality of touches. The series width of the electrode layer 66 can be determined according to the size of the user's finger. For example, the serial width can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, and the optimum tandem width value is 4 mm to 5 mm.
再者，值得強調的是，本實施例中觸控電極層66除了與金屬陰極層65是在同一道製程中完成，達到有效簡化製程手續外，並且由於觸控電極層66未與金屬陰極層65共用，因此有機發光二極體在作為顯示或觸控使用時，驅動端無需分時驅動顯示與觸控兩個時段，當有機發光二極體作為顯示功能時，可利用陽極層61與金屬陰極層65達成，而當有機發光二極體作為觸控功能使用時，可利用隔離柱(RIB)63上的觸控電極層66達成。 In addition, it should be emphasized that the touch electrode layer 66 in this embodiment is completed in the same process as the metal cathode layer 65, thereby effectively simplifying the process, and since the touch electrode layer 66 is not connected to the metal cathode layer. The 65 is shared. Therefore, when the organic light emitting diode is used as a display or a touch, the driving end does not need to drive the display and the touch for two periods. When the organic light emitting diode is used as the display function, the anode layer 61 and the metal can be utilized. The cathode layer 65 is achieved, and when the organic light emitting diode is used as a touch function, the touch electrode layer 66 on the spacer (RIB) 63 can be used.

另，本實施例與第一實施例的差異處在於蓋板77的下方或上方位置增設了一層觸控層78，因此除了自容式電容偵測方式之外尚可採用互容式電容偵測方式偵測觸控行為，且因觸控層78的感應方向與X軸向的觸控電極層76相互垂直，使其可進行X-Y兩個軸向的矩陣結構觸控行為，藉由每一條觸控電極層76輸出的順序作為辨識觸控行為的方向是由上至下，或是由下至上，或是藉由每一條觸控層78輸出的順序作為辨識觸控行為的 方向是由左至右，或是由右至左；並以此方式，藉以判斷手指對觸控電極層76及觸控層78的手勢滑動方向。 In addition, the difference between the embodiment and the first embodiment is that a touch layer 78 is added below or above the cover 77, so that mutual capacitance detection can be used in addition to the self-capacitance capacitance detection mode. The method detects the touch behavior, and because the sensing direction of the touch layer 78 and the touch electrode layer 76 of the X-axis are perpendicular to each other, the XY two-axis matrix structure touch behavior can be performed, by each touch The order in which the control electrode layer 76 is output is used to identify the touch behavior from top to bottom, or from bottom to top, or through the order of output of each touch layer 78. The direction is from left to right or from right to left; and in this way, the direction of the gesture sliding of the finger to the touch electrode layer 76 and the touch layer 78 is determined.
再者，在本實施例中，觸控電極層76與觸控層78之間係保有適當間距D，同時觸控電極層76與觸控層78之間在未有觸控反應時係存在著寄生電容，而寄生電容的電容值大小取決於適當間距D的寬度，當適當間距D的寬度愈大，寄生電容的電容值愈小，觸控反應的靈敏度愈佳，反之當適當間距D的寬度愈小，寄生電容的電容值愈大，觸控反應的靈敏度愈差；換言之，觸控電極層76與觸控層78之間的適當間距D其寬度會影響觸控反應的靈敏度，因此在設計適當間距D的寬度時需考量到驅動IC的驅動能力及面板的製程能力。 Moreover, in the embodiment, the touch electrode layer 76 and the touch layer 78 are maintained at an appropriate spacing D, and the touch electrode layer 76 and the touch layer 78 are present in the absence of a touch reaction. Parasitic capacitance, and the capacitance value of the parasitic capacitance depends on the width of the appropriate spacing D. When the width of the appropriate spacing D is larger, the capacitance value of the parasitic capacitance is smaller, the sensitivity of the touch reaction is better, and vice versa when the width of the appropriate spacing D is The smaller the capacitance value of the parasitic capacitance is, the worse the sensitivity of the touch response is. In other words, the proper spacing D between the touch electrode layer 76 and the touch layer 78 affects the sensitivity of the touch reaction, so the design is The width of the appropriate spacing D needs to take into account the driving capability of the driver IC and the process capability of the panel.
