Description
本發明有關於一種影像顯示器，且特別是有關於具有遮光層的影像顯示器。 The present invention relates to an image display, and more particularly to an image display having a light shielding layer.
目前常見的一些軟性影像顯示器，例如是有機電致發光顯示器(Organic Light Emitting Display，OLED)或是液晶顯示器(Liquid Crystal Display，LCD)，通常都包括影像顯示面板。影像顯示面板通常包括二塊軟性基板以及一框膠，其中這二塊軟性基板例如是彩色濾光基板與主動元件陣列基板，而影像顯示面板大多是藉由框膠將這兩塊軟性基板黏合而成。 Some conventional soft image displays, such as an Organic Light Emitting Display (OLED) or a Liquid Crystal Display (LCD), usually include an image display panel. The image display panel usually includes two flexible substrates and a frame glue. The two flexible substrates are, for example, a color filter substrate and an active device array substrate, and the image display panel mostly bonds the two flexible substrates by a frame glue. to make.
一般而言，隨著時間的過去，軟性基板的材料往往容易吸收水氣，以致於水或氧氣能穿透軟性基板而進入軟性影像顯示面板內部，對軟性影像顯示器造成不良的影響。 In general, over time, the material of the flexible substrate tends to absorb moisture so that water or oxygen can penetrate the flexible substrate and enter the interior of the flexible image display panel, which adversely affects the soft image display.
本發明實施例提供一種顯示面板，其所形成的保護層能降低水或氧氣能進入軟性影像顯示面板內部之情形。 Embodiments of the present invention provide a display panel capable of reducing a situation in which water or oxygen can enter the interior of a flexible image display panel.
本發明實施例提供一種顯示面板，所述顯示面板包括第一基板、保護層、主動元件陣列層、有機發光膜層以及第二基板。第一基板與第二基板結合。保護層位於第二基板以及第一基板之間，保護層具有一第一表面以及一相對於第一表面的第二表面，其中由第一表面至該第二表面劃分為一第一區域、一第二區域以及一第三區域，第二區域位於第一區域與第三區域之間，且第一區域及第三區域的氧濃度皆大於在第二區域的氧濃度。有機發光膜層位於主動元件陣列層以及第一基板之間。 Embodiments of the present invention provide a display panel including a first substrate, a protective layer, an active device array layer, an organic light emitting film layer, and a second substrate. The first substrate is combined with the second substrate. The protective layer is located between the second substrate and the first substrate, the protective layer has a first surface and a second surface opposite to the first surface, wherein the first surface to the second surface are divided into a first region, a The second region and a third region are located between the first region and the third region, and the oxygen concentrations of the first region and the third region are both greater than the oxygen concentration in the second region. The organic light emitting film layer is located between the active device array layer and the first substrate.
本發明實施例提供一種顯示裝置，所述顯示裝置包括前述之顯示面板、控制組件以及組裝殼體。控制組件控制顯示面板。電路板組件與顯示裝置配置於組裝殼體內。 Embodiments of the present invention provide a display device including the foregoing display panel, a control assembly, and an assembly housing. The control component controls the display panel. The circuit board assembly and the display device are disposed in the assembled housing.
綜上所述，本發明實施例所提供的保護層為緻密的金屬氧化層，且具有防水或氧氣穿透性。當水或氧氣穿透第二基板而由保護層的第一表面進入保護層的內部時，水或氧氣中的氧離子易使得保護層的金屬材料氧化進而形成緻密的金屬氧化層，從而得以防止保護層內部的金屬材料繼續氧化，進而降低顯示面板的水氧穿透率。值得說明的是，保護層的氧濃度由第二基板側至第一基板的變化為由高濃度漸減至低濃度最後再漸增至高濃度。即使第二基板選自於氧氣穿透率較高的基材，本發明實施例仍得以降低水或氧氣穿透進入顯示面板內的機率。 In summary, the protective layer provided by the embodiment of the present invention is a dense metal oxide layer and has waterproof or oxygen permeability. When water or oxygen penetrates the second substrate and enters the inside of the protective layer from the first surface of the protective layer, oxygen ions in water or oxygen easily oxidize the metal material of the protective layer to form a dense metal oxide layer, thereby preventing The metal material inside the protective layer continues to oxidize, thereby reducing the water oxygen permeability of the display panel. It is worth noting that the change in the oxygen concentration of the protective layer from the second substrate side to the first substrate is gradually decreased from a high concentration to a low concentration and finally increased to a high concentration. Even if the second substrate is selected from a substrate having a higher oxygen permeability, the embodiment of the present invention can reduce the probability of water or oxygen penetrating into the display panel.

Since the organic light-emitting film layer 150 is self-luminous, the display panel 2 may use only the organic light-emitting film layer 150 as incident light under different product considerations.
填充層F1配置於第一基板110與第二基板120之間的間隙，於本實施例中，填充層F1的材料可以是有機填充材或者是無機填充材。不過，本發明實施例並不對填充層F1的材料加以限定。 The filling layer F1 is disposed in a gap between the first substrate 110 and the second substrate 120. In this embodiment, the material of the filling layer F1 may be an organic filler or an inorganic filler. However, the embodiment of the present invention does not limit the material of the filling layer F1.
黏著層180是一種接著劑，而第一基板110可以藉由黏著層180而與第二基板120結合。詳細而言，黏著層180位於非顯示區域M2上，而圍繞顯示區域M1，並且黏合第一基板110與第二基板120。一般來說，黏著層180的材料主要是環氧樹脂，而依照硬化方式來看，黏著層180可以區分為熱硬化樹脂、或者是光硬化樹脂。不過，本發明並不對此加以限定。 The adhesive layer 180 is an adhesive, and the first substrate 110 can be bonded to the second substrate 120 by the adhesive layer 180. In detail, the adhesive layer 180 is located on the non-display area M2, surrounds the display area M1, and bonds the first substrate 110 and the second substrate 120. Generally, the material of the adhesive layer 180 is mainly epoxy resin, and the adhesive layer 180 can be distinguished as a thermosetting resin or a photohardening resin in terms of hardening. However, the invention is not limited thereto.
保護層130位於第二基板120以及第一基板110之間，保護層130位於顯示區域M1。保護層130具有第一表面S1以及一相對於第一表面S1的第二表面S2。於本實施例中，保護層130配置於第二基板120上，而第一表面S1與第二基板120接觸，第二表面S2與主動元件陣列層140接觸。 The protective layer 130 is located between the second substrate 120 and the first substrate 110, and the protective layer 130 is located in the display region M1. The protective layer 130 has a first surface S1 and a second surface S2 with respect to the first surface S1. In this embodiment, the protective layer 130 is disposed on the second substrate 120, and the first surface S1 is in contact with the second substrate 120, and the second surface S2 is in contact with the active device array layer 140.
保護層130為緻密的金屬氧化層，且具有防水或氧氣穿透性。而，保護層130的金屬材料選自於鋁、鋅、鈦、鎳、釩、錳、鎂、鈮、鉻及其混合所組成的群組其中之一種。當水或氧氣穿透第二基板120而由保護層130的第一表面S1進入保護層130的內部時，水或氧氣中的氧離子易使得保護層130的金屬材料氧化進而形成緻密的金屬氧化層，從而得以防止保護層130內部的金屬材料繼續氧化，進而降低顯示面板100的水氧穿透率。值得說明的是，保護層130的氧濃度由第二基板120側至第一基板110的變化為由高濃度漸減至低濃度最後再漸增至高濃度。 The protective layer 130 is a dense metal oxide layer and has water or oxygen permeability. The metal material of the protective layer 130 is selected from the group consisting of aluminum, zinc, titanium, nickel, vanadium, manganese, magnesium, strontium, chromium, and a mixture thereof. When water or oxygen penetrates the second substrate 120 and enters the inside of the protective layer 130 from the first surface S1 of the protective layer 130, oxygen ions in water or oxygen easily oxidize the metal material of the protective layer 130 to form a dense metal oxide. The layer prevents the metal material inside the protective layer 130 from continuing to oxidize, thereby reducing the water oxygen permeability of the display panel 100. It should be noted that the change of the oxygen concentration of the protective layer 130 from the second substrate 120 side to the first substrate 110 is gradually decreased from a high concentration to a low concentration and finally increased to a high concentration.
具體而言，保護層130可以透過真空蒸鍍法(Vacuum Evaporation Deposition)、真空濺鍍法或化學氣相沉積法等方式形成。在沉積金屬的過程中，藉由在不同時間點控制氧氣的流量，而製備出具有不同氧濃度的金屬氧化層。不過，本發明並不對保護層130的形成方法加以限定。 Specifically, the protective layer 130 can pass through a vacuum evaporation method (Vacuum) Evaporation Deposition), vacuum sputtering or chemical vapor deposition. In the process of depositing metal, metal oxide layers having different oxygen concentrations are prepared by controlling the flow rate of oxygen at different time points. However, the present invention does not limit the formation method of the protective layer 130.
圖2A以及圖2B為本發明實施例的保護層的氧濃度隨厚度變化示意圖。請參閱圖2A以及圖2B，詳細來說，保護層130的氧濃度變化由第一表面S1至第二表面S2可以大致劃分為第一區域I、第二區域II以及第三區域III，第二區域II位於第一區域I與第三區域III之間，而距離D定義為保護層130由第一表面S1至保護層130中任一點的距離。在第一區域I以及第三區域III中，保護層130的氧濃度皆大於在第二區域II的氧濃度。值得一提的是，於產品的考量，在第一區域I的氧濃度可以是小於第三區域III的氧濃度，如圖2A所繪示。此外，在第一區域I的氧濃度大於第三區域III的氧濃度，如圖2B所繪示。 2A and 2B are schematic diagrams showing changes in oxygen concentration with thickness of a protective layer according to an embodiment of the present invention. Referring to FIG. 2A and FIG. 2B , in detail, the oxygen concentration change of the protective layer 130 may be roughly divided into a first region I, a second region II, and a third region III by the first surface S1 to the second surface S2, and second. The region II is located between the first region I and the third region III, and the distance D is defined as the distance of the protective layer 130 from any of the first surface S1 to the protective layer 130. In the first region I and the third region III, the oxygen concentration of the protective layer 130 is greater than the oxygen concentration in the second region II. It is worth mentioning that, in terms of product considerations, the oxygen concentration in the first region I may be less than the oxygen concentration in the third region III, as depicted in Figure 2A. Further, the oxygen concentration in the first region I is greater than the oxygen concentration in the third region III, as illustrated in FIG. 2B.
詳細來說，當水或氧氣穿透第二基板120而由保護層130的第一表面S1進入時，在第一區域I中，保護層130中的氧濃度較高，保護層130中的緻密的金屬氧化層可以阻擋部分水或氧氣，而其他進入保護層130中的水或氧氣中的氧離子易與其他金屬原子產生氧化反應而形成緻密的金屬氧化層，進而緻密的金屬氧化層得以阻擋其他水或氧氣。 In detail, when water or oxygen penetrates the second substrate 120 and enters from the first surface S1 of the protective layer 130, in the first region I, the oxygen concentration in the protective layer 130 is high, and the dense layer in the protective layer 130 The metal oxide layer can block part of water or oxygen, and other oxygen ions in the water or oxygen entering the protective layer 130 are easily oxidized with other metal atoms to form a dense metal oxide layer, and the dense metal oxide layer is blocked. Other water or oxygen.
在第二區域II中的氧濃度較低，從而大部分水或氧氣中的氧離子得以在第二區域II中與保護層130的金屬材料氧化進而形成緻密的金屬氧化層。 The oxygen concentration in the second region II is low, so that most of the oxygen ions in the water or oxygen are oxidized in the second region II with the metal material of the protective layer 130 to form a dense metal oxide layer.
倘若，水或氧氣仍進入保護層130內部的第三區域III，保護層130中的氧濃度較高，因此保護層130中的緻密的金屬氧化層可以阻擋剩餘的水或氧氣，從而降低水或氧氣穿透保護層130而進入顯示面板100內部。 If water or oxygen still enters the third region III inside the protective layer 130, the oxygen concentration in the protective layer 130 is higher, so the dense metal oxide layer in the protective layer 130 can block the remaining water or oxygen, thereby reducing water or Oxygen penetrates the protective layer 130 and enters the inside of the display panel 100.
圖3為本發明第二實施例的顯示面板的結構示意圖。請參閱 圖3，本發明第二實施例的顯示面板200與第一實施例的顯示面板100二者結構相似，例如顯示面板100與200同樣都包括填充層F1。不過，顯示面板100與200之間仍存有差異。以下將僅介紹顯示面板100與200二者的差異，而顯示面板100與200二者相同的特徵則不再重複詳細敘述。 3 is a schematic structural view of a display panel according to a second embodiment of the present invention. See 3, the display panel 200 of the second embodiment of the present invention is similar in structure to the display panel 100 of the first embodiment. For example, the display panels 100 and 200 both include a filling layer F1. However, there is still a difference between the display panels 100 and 200. Only the differences between the display panels 100 and 200 will be described below, and the features of the display panels 100 and 200 will not be repeated.

於本實施例中，有機發光膜層250可以是由不同顏色的有機發光膜層所形成的配列，例如是紅色、藍色以及綠色。由於有機發光膜層250具有不同顏色，因此顯示面板200也可以不需要任何彩色濾光片170a。不過，圖1以及圖3所示的彩色濾光層170以及有機發光膜層150、250僅供舉例說明，並非用來限定本發明。 In the present embodiment, the organic light-emitting film layer 250 may be an array formed of organic light-emitting film layers of different colors, such as red, blue, and green. Since the organic light emitting film layer 250 has a different color, the display panel 200 may not require any color filter 170a. However, the color filter layer 170 and the organic light-emitting film layers 150 and 250 shown in FIGS. 1 and 3 are for illustrative purposes only and are not intended to limit the invention.
於本發明實施例中，為了更佳地防止水或氧氣穿透第二基板120進入顯示面板200，顯示面板200可以更包括阻水氧層292、294。阻水氧層292、294分別設置於保護層230的第一表面S1以及第二表面S2之上。不過，為了製程工序的考量，阻水氧層292、294亦可以皆位於保護層230的同一側。值得一提的是，阻水氧層292、294可以是氮化矽(SiNx)、氧化矽(SiOx)、氮氧化矽(SiOxNy)或三氧化二鋁(Al2O3)等具有防水或氧氣穿透性的無機材料。或者阻水氧層292、294也可以是使用有機材料。本發明並不對阻水氧層292、294的配置位置以及材料加以限定。 In the embodiment of the present invention, in order to prevent water or oxygen from penetrating the second substrate 120 into the display panel 200, the display panel 200 may further include a water blocking oxygen layer 292, 294. The water blocking oxygen layers 292 and 294 are respectively disposed on the first surface S1 and the second surface S2 of the protective layer 230. However, for the process steps, the water blocking oxygen layers 292, 294 may also be located on the same side of the protective layer 230. It is worth mentioning that the water blocking oxygen layer 292, 294 may be tantalum nitride (SiN x ), yttrium oxide (SiO x ), lanthanum oxynitride (SiO x N y ) or aluminum oxide (Al 2 O 3 ). An inorganic material that is water-repellent or oxygen-permeable. Alternatively, the water blocking oxygen layer 292, 294 may be an organic material. The present invention does not limit the arrangement locations and materials of the water blocking oxygen layers 292, 294.
於本實施例中，保護層230位於顯示區域M1且位於阻水氧層292、294之間。保護層230為緻密的金屬氧化層，且具有防水 或氧氣穿透性。保護層130的金屬材料選自於鋁、鋅、鈦、鎳、釩、錳、鎂、鈮、鉻及其混合所組成的群組其中之一種。當水或氧氣穿透第二基板120以及阻水氧層292而由保護層230的第一表面S1進入保護層130的內部時，水或氧氣中的氧離子易使得保護層230的金屬材料氧化進而形成緻密的金屬氧化層，從而得以防止保護層230內部的金屬材料繼續氧化，進而降低顯示面板200的水氧穿透率。值得說明的是，保護層230的氧濃度由第二基板120側至第一基板110的變化為由高濃度漸減至低濃度最後再漸增至高濃度。 In the present embodiment, the protective layer 230 is located in the display region M1 and between the water blocking oxygen layers 292, 294. The protective layer 230 is a dense metal oxide layer and is waterproof Or oxygen permeability. The metal material of the protective layer 130 is selected from the group consisting of aluminum, zinc, titanium, nickel, vanadium, manganese, magnesium, strontium, chromium, and a mixture thereof. When water or oxygen penetrates the second substrate 120 and the water blocking oxygen layer 292 and enters the inside of the protective layer 130 from the first surface S1 of the protective layer 230, oxygen ions in water or oxygen easily oxidize the metal material of the protective layer 230. Further, a dense metal oxide layer is formed, thereby preventing the metal material inside the protective layer 230 from continuing to oxidize, thereby lowering the water oxygen permeability of the display panel 200. It should be noted that the change of the oxygen concentration of the protective layer 230 from the second substrate 120 side to the first substrate 110 is gradually decreased from a high concentration to a low concentration and finally increased to a high concentration.

Referring to FIG. 4 , the display 300 includes a display panel 100 , an assembly housing 320 , and a control component 340 . The control component 340 and the display panel 100 are both disposed in the assembly housing 320 . The assembly housing 320 can be coupled to the display panel 100 by snapping or screwing, and the control assembly 340 controls the display panel 100, such as opening or closing.
值得說明的是，顯示面板100也可以替換前述實施例中的顯示面板200，或者是其他軟性顯示面板，例如是，液晶軟性顯示面板或是電泳式軟性顯示面板等。本發明並不以顯示面板100的種類為限。由於顯示面板100可以替換成其他軟性顯示面板，因此顯示面板100可以應用於多種不同的顯示器產品。也就是說，顯示器300可以是手持電子裝置的螢幕(如圖4所示)、電子紙等，其中上述手持電子裝置例如是手機、手錶、掌上型遊樂器或個人數位助理器(Personal Digital Assistant，PDA)等。 It should be noted that the display panel 100 may also replace the display panel 200 in the foregoing embodiment, or other flexible display panels, such as a liquid crystal flexible display panel or an electrophoretic flexible display panel. The present invention is not limited to the type of display panel 100. Since the display panel 100 can be replaced with other flexible display panels, the display panel 100 can be applied to a variety of different display products. That is, the display 300 can be a screen of a handheld electronic device (as shown in FIG. 4), an electronic paper, etc., wherein the handheld electronic device is, for example, a mobile phone, a watch, a palm-type amusement instrument, or a personal digital assistant (Personal Digital Assistant, PDA) and so on.
綜上所述，本發明實施例所提供的保護層為緻密的金屬氧化層，且具有防水或氧氣穿透性。當水或氧氣穿透第二基板而由保護層的第一表面進入保護層的內部時，水或氧氣中的氧離子易使得保護層的金屬材料氧化進而形成緻密的金屬氧化層，從而得以防止保護層內部的金屬材料繼續氧化，進而降低顯示面板的水氧 穿透率。值得說明的是，保護層的氧濃度由第二基板側至第一基板的變化為由高濃度漸減至低濃度最後再漸增至高濃度。即使第二基板選自於氧氣穿透率較高的基材，本發明實施例仍得以降低水或氧氣穿透進入顯示面板內的機率。 In summary, the protective layer provided by the embodiment of the present invention is a dense metal oxide layer and has waterproof or oxygen permeability. When water or oxygen penetrates the second substrate and enters the inside of the protective layer from the first surface of the protective layer, oxygen ions in water or oxygen easily oxidize the metal material of the protective layer to form a dense metal oxide layer, thereby preventing The metal material inside the protective layer continues to oxidize, thereby reducing the water oxygen of the display panel Penetration rate. It is worth noting that the change in the oxygen concentration of the protective layer from the second substrate side to the first substrate is gradually decreased from a high concentration to a low concentration and finally increased to a high concentration. Even if the second substrate is selected from a substrate having a higher oxygen permeability, the embodiment of the present invention can reduce the probability of water or oxygen penetrating into the display panel.
