為能進一步闡述本發明達成預定目的所採取的技術手段及功效，以下結合附圖及較佳實施方式，對本申請作出如下詳細說明。 In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the present application will be given in conjunction with the accompanying drawings and preferred implementation modes.

請參閱圖1，圖1為一種減薄的觸控顯示裝置900的剖面圖，其包括依次層疊設置的背光板990、薄膜電晶體層970、觸控層950、液晶層910以及同層設置的密封層930、彩色濾光層913、基材層911以及偏光層933。 Please refer to FIG. 1. FIG. 1 is a cross-sectional view of a thinned touch display device 900, which includes a backlight plate 990, a thin film transistor layer 970, a touch layer 950, a liquid crystal layer 910, and a layer arranged in the same layer. The sealing layer 930 , the color filter layer 913 , the substrate layer 911 and the polarizing layer 933 .

當觸控顯示裝置900應用於一移動終端中時，所述移動終端可包括一光學感測模組a，光學感測模組a設於遮蔽層980遠離薄膜電晶體層970的一邊，且部分被遮蔽層980覆蓋。光學感測模組a可以為紅外感測器、紅外發光二極體、可見光攝像模組、發光二極體、光線感應器以及紅外攝像頭中的一種或任意組合。此時薄膜電晶體層970遠離觸控層950的一側還設有遮蔽層980，用於防止可見光穿透。具體為遮蔽層980完全覆蓋光學感測模組a中與紅外光相關的每一光學元件，且不覆蓋任何與紅外光無關的光學元件。 When the touch display device 900 is applied to a mobile terminal, the mobile terminal may include an optical sensing module a, the optical sensing module a is arranged on the side of the shielding layer 980 away from the thin film transistor layer 970, and a part Covered by masking layer 980 . The optical sensing module a may be one or any combination of an infrared sensor, an infrared light-emitting diode, a visible light camera module, a light-emitting diode, a light sensor, and an infrared camera. At this time, the side of the TFT layer 970 away from the touch layer 950 is further provided with a shielding layer 980 for preventing visible light from penetrating. Specifically, the shielding layer 980 completely covers every optical element related to infrared light in the optical sensing module a, and does not cover any optical element not related to infrared light.

觸控顯示裝置900藉由將觸控層950設於薄膜電晶體層970與液晶層910之間，使得控制觸控層950與控制液晶層910的電路走線均可設置於薄膜電晶體層970上，從而減小觸控顯示裝置900的體積。同時，藉由設置基材層911的材質為玻璃，厚度約為2mm，可以在支撐彩色濾光層913的同時起到蓋板的作用，從而不需要額外設置玻璃蓋板，減小了觸控顯示裝置900的體積。 The touch display device 900 arranges the touch layer 950 between the thin film transistor layer 970 and the liquid crystal layer 910, so that the circuit traces for controlling the touch layer 950 and the liquid crystal layer 910 can be arranged in the thin film transistor layer 970 , so as to reduce the volume of the touch display device 900 . At the same time, by setting the material of the base material layer 911 as glass, with a thickness of about 2mm, it can support the color filter layer 913 and play the role of a cover plate at the same time, so that no additional glass cover plate is required, which reduces the need for touch control. The volume of the device 900 is displayed.

然而，在該種結構中存在如下問題：由於觸控顯示裝置900還需要設於基材層911遠離彩色濾光層913一側的偏光層933，此時，偏光層933處於觸控顯示裝置900的最外層，且偏光層933不能覆蓋光學感測模組a，因此偏光層933僅部分覆蓋基材層911，使得觸控顯示裝置900的外側表面不平整。同時，由於偏光層933的材料為塑膠，使用手感不佳且容易損壞。 However, there is the following problem in this structure: since the touch display device 900 also needs to be provided on the side of the substrate layer 911 away from the color filter layer 913, the polarizing layer 933, at this time, the polarizing layer 933 is located in the touch display device 900 and the polarizing layer 933 cannot cover the optical sensing module a, so the polarizing layer 933 only partially covers the substrate layer 911 , making the outer surface of the touch display device 900 uneven. At the same time, since the material of the polarizing layer 933 is plastic, it does not feel good in use and is easily damaged.

本申請實施例在此基礎上提出一種觸控顯示裝置和應用於所述觸控顯示裝置的偏振濾光板。請參閱圖2，偏振濾光板100包括：濾光部10、偏光 片30以及蓋板50。其中，濾光部10包括層疊設置的基材層11和彩色濾光層13；偏光片30設於彩色濾光層13遠離基材層11的一側，包括依次層疊設置的光補償層31、偏光層33和保護層35。光補償層31靠近彩色濾光層13，用於調整穿過光補償層31的光線的相位，偏光層33包括基底層331和雙向吸收層333，用於實現偏光作用。在偏振濾光板100應用到觸控顯示裝置中時，濾光部10比偏光片30更靠近觸控顯示裝置的觀察者側。 On this basis, embodiments of the present application propose a touch display device and a polarizing filter applied to the touch display device.

Filter units 131a, 131b and 131c, the colors of different sub-filter units 131a, 131b and 131c in the same filter unit 131 are different, for example, the sub-filter unit 131a can be red, used to make the red primary color light pass through and filter out light of other colors; the sub-filter unit 131b can be green, used to transmit the green primary color light and filter out other colors of light; the sub-filter unit 131c can be blue, used to transmit the blue primary color light And filter out other colors of light. The black matrix 133 is also used to separate each sub-filter unit in the same filter unit 131 . In other embodiments, each filter unit 131 may also include a plurality of sub-filter units of varying numbers, for example, one filter unit 131 includes one sub-filter unit 131a, two sub-filter units 131b and one sub-filter unit 131b.

在一實施例中，基底層331為聚乙烯醇(polyvinyl alcohol，PVA)薄膜，雙向吸收層333的材料為碘化鉀，該PVA薄膜經染色後吸附具有雙向吸收功能的碘分子以形成雙向吸收層333，藉由從PVA薄膜兩側進行拉伸使碘分子在PVA薄膜上有序排列，形成具有均勻雙向吸收性能的偏光層33，從而實現偏光的效果。在其他實施例中，雙向吸收層333的材料還可以是其他具有雙向吸收功 能的染料分子，藉由浸泡染色附著在基底層331後進行延展，從而使偏光層33具有偏光性。 In one embodiment, the base layer 331 is polyvinyl alcohol (polyvinyl alcohol, PVA) film, and the material of the two-way absorbing layer 333 is potassium iodide. , by stretching from both sides of the PVA film, the iodine molecules are ordered on the PVA film to form a polarizing layer 33 with uniform bidirectional absorption properties, thereby achieving the effect of polarizing light. In other embodiments, the material of the bidirectional absorbing layer 333 can also be other materials with bidirectional absorbing work. The dye molecules with energy are attached to the base layer 331 by soaking and dyeing, and then extended, so that the polarizing layer 33 has polarizing properties.

在一實施例中，保護層35的材料為三醋酸纖維素(Triacetyl Cellulose，TAC)，TAC材料具有較高的光穿透性，因此保護層35在保護偏光層33的同時不會影響顯示效果。 In one embodiment, the protective layer 35 is made of triacetyl cellulose (Triacetyl Cellulose, TAC), and the TAC material has high light penetration, so the protective layer 35 will not affect the display effect while protecting the polarizing layer 33. .

在一實施例中，光補償層31可以為位相差膜，用於對穿過所述光補償層31的光的相位進行調整。請一併參閱圖2和圖4，當偏振濾光板100應用於一觸控顯示裝置200時，從背光板290出射的光線會經由液晶層210入射至光補償層31，此時由於光線在液晶層210中發生多次折射，會引發光的干涉，從而影響顯示效果。所述位相差膜可以對此進行光學補償，從而消除因光的干涉造成的影響。此外，由於光線通過液晶層時會在液晶分子的作用下發生亮度的變化，該變化是由於液晶分子的偏轉造成的，因此從偏振濾光板100的側方觀察時，可能會出現液晶層210的作用不明顯，也即出現漏光現象。所述位相差膜可以對此進行光學補償，從而提高光線在大視角下的顯示效果。 In an embodiment, the optical compensation layer 31 may be a retardation film, which is used to adjust the phase of light passing through the optical compensation layer 31 . Please refer to FIG. 2 and FIG. 4 together. When the polarizing filter plate 100 is applied to a touch display device 200, the light emitted from the backlight plate 290 will enter the optical compensation layer 31 through the liquid crystal layer 210. Multiple refractions occur in the layer 210, which will cause light interference, thereby affecting the display effect. The retardation film can optically compensate for this, thereby eliminating the influence caused by light interference. In addition, when light passes through the liquid crystal layer, brightness changes will occur under the action of liquid crystal molecules. This change is caused by the deflection of liquid crystal molecules. Therefore, when viewed from the side of the polarizing filter plate 100, the liquid crystal layer 210 may appear The effect is not obvious, that is, light leakage occurs. The retardation film can optically compensate for this, thereby improving the display effect of light at a large viewing angle.

在一實施例中，請繼續參閱圖2，光補償層31也可用於保護偏光層33，因此不需要在偏光層33遠離保護層35的一側再額外設置一保護層，從而減小了偏振濾光板100的厚度。 In one embodiment, please continue to refer to FIG. 2, the optical compensation layer 31 can also be used to protect the polarizing layer 33, so there is no need to set an additional protective layer on the side of the polarizing layer 33 away from the protective layer 35, thereby reducing the polarization. The thickness of the filter plate 100.

在一實施例中，蓋板50設於偏光片30遠離濾光部10的一側。蓋板50的材料為經過化學強化的玻璃，即採用高純度的硝酸鉀溶液搭配催化劑作用於玻璃材料上，使玻璃結構表面的鉀離子與鈉離子進行離子交換，從而形成強化層。蓋板50的厚度為0.2mm，由於經過化學強化處理，蓋板50的硬度提高，且防劃傷抗衝擊能力提高，從而可以更好的保護偏光片30。此外，由於經過化學強化處理，蓋板50的厚度可以進一步減薄，從而減小偏振濾光板100的厚度。 In one embodiment, the cover plate 50 is disposed on a side of the polarizer 30 away from the filter portion 10 . The cover plate 50 is made of chemically strengthened glass, that is, a high-purity potassium nitrate solution and a catalyst are used to act on the glass material, so that potassium ions and sodium ions on the surface of the glass structure are ion-exchanged, thereby forming a strengthening layer. The thickness of the cover plate 50 is 0.2 mm. Due to the chemical strengthening treatment, the hardness of the cover plate 50 is improved, and the anti-scratch and impact resistance are improved, so that the polarizer 30 can be better protected. In addition, due to the chemical strengthening treatment, the thickness of the cover plate 50 can be further reduced, thereby reducing the thickness of the polarizing filter plate 100 .

在一實施例中，非偏光窗34的開設方法為藉由雷射蝕刻，將雙向吸收層333中的碘化合物進行剝離。在其他實施例中，還可以藉由鹼性溶液將雙向吸收層333中的碘化合物還原成碘離子，使其失去極化性能，從而喪失偏光性。 In one embodiment, the opening method of the non-polarizing window 34 is to peel off the iodine compound in the bidirectional absorption layer 333 by laser etching. In other embodiments, the iodine compound in the two-way absorbing layer 333 can also be reduced to iodide ions by an alkaline solution, so that it loses its polarizability, thereby losing its polarization.
