Description
本發明是有關於一種顯示裝置，且特別是有關於一種薄型顯示裝置。The present invention relates to a display device, and more particularly to a thin display device.
近年來，傳統的陰極射線管顯示裝置已逐漸被薄型顯示裝置所取代。目前常見的薄型顯示裝置包括液晶顯示裝置、電漿顯示裝置、電泳顯示裝置及有機發光二極體顯示裝置等，其中又以液晶顯示裝置的普及率最高。In recent years, conventional cathode ray tube display devices have been gradually replaced by thin display devices. At present, thin display devices commonly used include liquid crystal display devices, plasma display devices, electrophoretic display devices, and organic light emitting diode display devices, among which liquid crystal display devices have the highest penetration rate.
液晶顯示裝置包括液晶顯示面板以及用以提供顯示光源的背光模組。目前常見的液晶顯示面板為薄膜電晶體液晶顯示面板，其包括薄膜電晶體陣列基板、彩色濾光基板以及配置於其間的液晶層。近來發展出一種將閘極驅動電路整合於薄膜電晶體陣列基板的技術，即所謂的gate on array(GOA)技術。GOA技術是在製作薄膜電晶體陣列基板時，同時製作出閘極驅動電路。閘極驅動電路可用於取代閘極驅動晶片，如此能節省生產成本。The liquid crystal display device includes a liquid crystal display panel and a backlight module for providing a display light source. At present, a common liquid crystal display panel is a thin film transistor liquid crystal display panel, which includes a thin film transistor array substrate, a color filter substrate, and a liquid crystal layer disposed therebetween. Recently, a technique of integrating a gate driving circuit into a thin film transistor array substrate, a so-called gate on array (GOA) technique, has been developed. The GOA technology simultaneously produces a gate drive circuit when fabricating a thin film transistor array substrate. The gate drive circuit can be used to replace the gate drive chip, which saves production costs.
圖1是習知一種應用GOA技術之液晶顯示裝置的局部剖面示意圖。請參照圖1，習知液晶顯示裝置100包括內框110、外框120、液晶顯示面板130以及背光模組140。內框110具有用以支撐液晶顯示面板130的支撐部112，而背光模組140配置於液晶顯示面板130下方。外框120包括相組立的前框122與背框124，且外框120用以包覆內框110、液晶顯示面板130與背光模組140。液晶顯示面板130包括薄膜電晶體陣列基板132、彩色濾光基板134、框膠136以及液晶層138。框膠136與液晶層138配置於薄膜電晶體陣列基板132與彩色濾光基板134之間，且液晶層138配置於框膠136所圍出的區域內。1 is a partial cross-sectional view showing a conventional liquid crystal display device using GOA technology. Referring to FIG. 1 , the conventional liquid crystal display device 100 includes an inner frame 110 , an outer frame 120 , a liquid crystal display panel 130 , and a backlight module 140 . The inner frame 110 has a support portion 112 for supporting the liquid crystal display panel 130 , and the backlight module 140 is disposed under the liquid crystal display panel 130 . The outer frame 120 includes a front frame 122 and a back frame 124. The outer frame 120 is used to cover the inner frame 110, the liquid crystal display panel 130, and the backlight module 140. The liquid crystal display panel 130 includes a thin film transistor array substrate 132, a color filter substrate 134, a sealant 136, and a liquid crystal layer 138. The sealant 136 and the liquid crystal layer 138 are disposed between the thin film transistor array substrate 132 and the color filter substrate 134, and the liquid crystal layer 138 is disposed in a region surrounded by the sealant 136.
承上述，薄膜電晶體陣列基板132具有用GOA技術製作出的閘極驅動電路133，而為了保護閘極驅動電路133，液晶層138需向薄膜電晶體陣列基板132的邊緣延伸，以覆蓋閘極驅動電路133。相應地，框膠136需移至更接近薄膜電晶體陣列基板132之邊緣的位置。然而，此將導致前框122之位於液晶顯示面板130上方的末端123是對應至液晶層138而非框膠136。如此，當前框122遭受外力F1按壓時，前框122將會影響到液晶層138，導致液晶顯示裝置100在顯示時產生水波紋。As described above, the thin film transistor array substrate 132 has the gate driving circuit 133 fabricated by the GOA technique, and in order to protect the gate driving circuit 133, the liquid crystal layer 138 needs to extend toward the edge of the thin film transistor array substrate 132 to cover the gate. Drive circuit 133. Accordingly, the sealant 136 needs to be moved closer to the edge of the thin film transistor array substrate 132. However, this will cause the end 123 of the front frame 122 above the liquid crystal display panel 130 to correspond to the liquid crystal layer 138 instead of the sealant 136. As such, when the current frame 122 is pressed by the external force F1, the front frame 122 will affect the liquid crystal layer 138, causing the liquid crystal display device 100 to generate water ripples upon display.
圖2是習知另一種應用GOA技術之液晶顯示裝置的局部剖面示意圖。請參照圖2，為了改善上述缺點，習知液晶顯示裝置100’係縮短外框120’之前框122’的延伸長度，使前框122’的末端123退縮至薄膜電晶體陣列基板132之邊緣。如此，雖可避免水波紋的現象，但會導致漏光現象。2 is a partial cross-sectional view showing another conventional liquid crystal display device using the GOA technology. Referring to Fig. 2, in order to improve the above disadvantages, the conventional liquid crystal display device 100' shortens the extension length of the front frame 122' of the outer frame 120' to retract the end 123 of the front frame 122' to the edge of the thin film transistor array substrate 132. In this way, although the phenomenon of water ripple can be avoided, it will cause light leakage.
更詳細地說，由於彩色濾光基板134之遮光層135在製作時無法延伸至邊緣，所以會有從液晶顯示面板130之邊緣出射的雜散光142。前框122’雖可用來遮擋雜散光142，但在前框122’之延伸長度縮短後，前框122’的遮光範圍亦隨之縮短。所以，雜散光142容易穿出液晶顯示裝置100’，造成漏光現象。More specifically, since the light shielding layer 135 of the color filter substrate 134 cannot be extended to the edge at the time of fabrication, stray light 142 emitted from the edge of the liquid crystal display panel 130 may be present. Although the front frame 122' can be used to block the stray light 142, the light-shielding range of the front frame 122' is also shortened after the extension length of the front frame 122' is shortened. Therefore, the stray light 142 easily passes through the liquid crystal display device 100', causing a light leakage phenomenon.
本發明提供一種顯示裝置，以防止漏光並避免外框受壓迫產生水波紋。The present invention provides a display device to prevent light leakage and to prevent the outer frame from being pressed to generate water ripples.
為達上述優點，本發明提出一種顯示裝置，其包括內框、顯示面板以及外框。內框具有向內延伸的支撐部，顯示面板配置於支撐部上，且顯示面板具有二基板與設置於此二基板之間的框膠。外框包覆內框及顯示面板，且外框具有延伸至顯示面板上方的固定部以及從固定部之末端延伸出的遮光部。固定部係接觸顯示面板，且連接遮光部的固定部之末端位於顯示面板之框膠的正上方。遮光部係延伸至框膠所圍出的區域上方，且遮光部與顯示面板之間相隔一段距離。In order to achieve the above advantages, the present invention provides a display device including an inner frame, a display panel, and an outer frame. The inner frame has a support portion extending inwardly, and the display panel is disposed on the support portion, and the display panel has two substrates and a sealant disposed between the two substrates. The outer frame covers the inner frame and the display panel, and the outer frame has a fixing portion extending to the upper side of the display panel and a light blocking portion extending from the end of the fixing portion. The fixing portion contacts the display panel, and the end of the fixing portion connecting the light shielding portion is located directly above the sealant of the display panel. The light shielding portion extends over the area enclosed by the sealant, and the light shielding portion is spaced apart from the display panel by a distance.
在本發明之一實施例中，上述之顯示面板為液晶顯示面板，且更包括液晶層。液晶層配置於上述二基板之間並位於框膠所圍出的區域內，而位於框膠下方的基板為具有整合有驅動電路的主動元件陣列基板。驅動電路係位於框膠所圍出的區域下方，而液晶層係覆蓋驅動電路。In an embodiment of the invention, the display panel is a liquid crystal display panel, and further includes a liquid crystal layer. The liquid crystal layer is disposed between the two substrates and located in a region surrounded by the sealant, and the substrate under the sealant is an active device array substrate having a drive circuit integrated therein. The drive circuit is located below the area enclosed by the sealant, and the liquid crystal layer covers the drive circuit.
在本發明之一實施例中，上述之驅動電路為閘極驅動電路。In an embodiment of the invention, the driving circuit is a gate driving circuit.
在本發明之一實施例中，上述之顯示面板更包括偏光片，配置在位於框膠上方的基板上，而遮光部係延伸至偏光片上方。In an embodiment of the invention, the display panel further includes a polarizer disposed on the substrate above the sealant, and the light shielding portion extends above the polarizer.
在本發明之一實施例中，上述之顯示裝置更包括背光模組，其配置於內框內，且位於顯示面板下方。In an embodiment of the invention, the display device further includes a backlight module disposed in the inner frame and located under the display panel.
在本發明之一實施例中，上述之外框包括相組立的第一框與第二框，其中第一框具有上述之固定部與上述之遮光部。In an embodiment of the invention, the outer frame includes a first frame and a second frame that are assembled, wherein the first frame has the fixing portion and the light shielding portion.
在本發明之一實施例中，上述之遮光部具有從固定部之末端朝遠離顯示面板之方向延伸的第一段以及連接第一段且平行顯示面板的第二段。In an embodiment of the invention, the light shielding portion has a first segment extending from a distal end of the fixing portion in a direction away from the display panel, and a second segment connecting the first segment and the parallel display panel.
在本發明之顯示裝置中，遮光部能提供良好的遮光效果，以防止漏光。而且，由於遮光部與顯示面板之間相隔一段距離，當遮光部受到外力按壓時，遮光部與顯示面板之間的空間可作為緩衝空間，以防止遮光部直接壓迫顯示面板的液晶層，形成水波紋的缺失。In the display device of the present invention, the light shielding portion can provide a good light shielding effect to prevent light leakage. Moreover, since the light shielding portion is spaced apart from the display panel by a distance, when the light shielding portion is pressed by the external force, the space between the light shielding portion and the display panel can serve as a buffer space to prevent the light shielding portion from directly pressing the liquid crystal layer of the display panel to form water. The absence of ripples.

圖3是本發明一實施例之一種顯示裝置的局部剖面示意圖。請參照圖3，本實施例之顯示裝置200包括內框210、外框220以及顯示面板230。內框210具有向內延伸的支撐部212，而顯示面板230配置於支撐部212上。顯示面板230具有二基板232、234與設置於此二基板232、234之間的框膠236。外框220包覆內框210及顯示面板230。3 is a partial cross-sectional view showing a display device in accordance with an embodiment of the present invention. Referring to FIG. 3 , the display device 200 of the embodiment includes an inner frame 210 , an outer frame 220 , and a display panel 230 . The inner frame 210 has a support portion 212 extending inward, and the display panel 230 is disposed on the support portion 212. The display panel 230 has two substrates 232, 234 and a sealant 236 disposed between the two substrates 232, 234. The outer frame 220 covers the inner frame 210 and the display panel 230.
在本實施例中，顯示面板230例如是液晶顯示面板，但在其他實施例中，顯示面板可為電漿顯示面板、電泳顯示面板、有機發光二極體顯示面板或其他類型的顯示面板。在顯示面板230為液晶顯示面板的實施例中，顯示面板230更包括液晶層238，其配置於上述二基板232、234之間並位於框膠236所圍出的區域A內。此外，位於框膠236上方的基板234例如為彩色濾光基板，而位於框膠236下方的基板232例如為主動元件陣列基板(如薄膜電晶體陣列基板)，且此主動元件陣列基板整合有驅動電路233。驅動電路233係位於框膠236所圍出的區域A下方，而液晶層238係覆蓋驅動電路233。此驅動電路233例如為閘極驅動電路，但不以此為限。In this embodiment, the display panel 230 is, for example, a liquid crystal display panel, but in other embodiments, the display panel may be a plasma display panel, an electrophoretic display panel, an organic light emitting diode display panel, or other types of display panels. In the embodiment in which the display panel 230 is a liquid crystal display panel, the display panel 230 further includes a liquid crystal layer 238 disposed between the two substrates 232 and 234 and located in a region A surrounded by the sealant 236. In addition, the substrate 234 located above the sealant 236 is, for example, a color filter substrate, and the substrate 232 under the sealant 236 is, for example, an active device array substrate (such as a thin film transistor array substrate), and the active device array substrate is integrated with a drive. Circuit 233. The driving circuit 233 is located below the area A surrounded by the sealant 236, and the liquid crystal layer 238 covers the driving circuit 233. The driving circuit 233 is, for example, a gate driving circuit, but is not limited thereto.
承上述，顯示面板230可更包括二偏光片237、239。偏光片237配置在位於框膠236下方的基板232下方，而偏光片239配置在位於框膠236上方的基板234上方。此外，在顯示面板230為非自發光性顯示面板(如液晶顯示面板)的實施例中，顯示裝置200可更包括背光模組240。此背光模組240配置於內框210內，且位於顯示面板230下方，以提供顯示光源至顯示面板230。背光模組240例如是側邊入光式背光模組，而背光模組240的導光板(圖中未示)可與內框210的支撐部212接觸，以支撐內框210，然不限於此，亦可更換其他種類的背光模組，如直下式背光模組。In the above, the display panel 230 may further include two polarizers 237 and 239. The polarizer 237 is disposed under the substrate 232 under the sealant 236, and the polarizer 239 is disposed above the substrate 234 above the sealant 236. In addition, in an embodiment where the display panel 230 is a non-self-luminous display panel (such as a liquid crystal display panel), the display device 200 may further include a backlight module 240. The backlight module 240 is disposed in the inner frame 210 and below the display panel 230 to provide a display light source to the display panel 230 . The backlight module 240 is, for example, a side-lit backlight module, and the light guide plate (not shown) of the backlight module 240 can be in contact with the support portion 212 of the inner frame 210 to support the inner frame 210, but is not limited thereto. Other types of backlight modules, such as direct-lit backlight modules, can also be replaced.
圖4是圖3中外框之第一框的立體示意圖。請參照圖3與圖4，上述之外框220具有延伸至顯示面板230上方的固定部221以及從固定部221之末端221a延伸出的遮光部223。固定部221係接觸顯示面板230，以固定顯示面板230。連接遮光部223的固定部221之末端221a係位於顯示面板230之框膠236的正上方。遮光部223係延伸至框膠236所圍出的區域A上方，且遮光部223與顯示面板230之間相隔一段距離。此外框220可例如包括相組立的第一框222與第二框224，其中第一框222具有上述之固定部221與上述之遮光部223。另外，遮光部223可例如是延伸至偏光片239上方，以達到較佳的遮光效果。此外，遮光部223例如具有從固定部221之末端221a朝遠離顯示面板230之方向延伸的第一段223a以及連接第一段223a且平行顯示面板230的第二段223b。4 is a perspective view of the first frame of the outer frame of FIG. 3. Referring to FIGS. 3 and 4 , the outer frame 220 has a fixing portion 221 extending above the display panel 230 and a light blocking portion 223 extending from the end 221 a of the fixing portion 221 . The fixing portion 221 contacts the display panel 230 to fix the display panel 230. The end 221a of the fixing portion 221 connecting the light shielding portion 223 is located directly above the sealant 236 of the display panel 230. The light shielding portion 223 extends over the area A surrounded by the sealant 236, and the light blocking portion 223 is spaced apart from the display panel 230 by a distance. The frame 220 may include, for example, a first frame 222 and a second frame 224, wherein the first frame 222 has the fixing portion 221 and the light blocking portion 223 described above. In addition, the light shielding portion 223 may extend over the polarizer 239, for example, to achieve a better light shielding effect. Further, the light shielding portion 223 has, for example, a first segment 223a extending from the distal end 221a of the fixing portion 221 in a direction away from the display panel 230, and a second segment 223b connecting the first segment 223a and parallel to the display panel 230.
在本實施例中，由於遮光部223與顯示面板230之間相隔一段距離，當遮光部223受到外力F2按壓時，遮光部223與顯示面板230之間的空間可作為緩衝空間，以避免外力透過遮光部223、偏光片239及基板234而傳遞至液晶層238。而且，接觸顯示面板230的固定部221其末端221a是位於框膠236的正上方，當外力F2傳遞至固定部221時，固定部221是壓迫到顯示面板230的框膠236而非液晶層238，透過框膠236來吸收外力F2的壓迫。因此，本實施例之顯示裝置200可防止施加於外框220的外力F2造成顯示面板230在顯示時產生水波紋現象，或是防止外力F2對顯示面板230造成損害。此外，相較於習知液晶顯示裝置100’(如圖2所示)的外框120’，本實施例之顯示裝置200的外框220因具有延伸至偏光片239上方的遮光部223，所以能有效遮擋從顯示面板230之邊緣出射的雜散光242，以避免產生漏光現象。In this embodiment, since the light shielding portion 223 and the display panel 230 are separated by a distance, when the light shielding portion 223 is pressed by the external force F2, the space between the light shielding portion 223 and the display panel 230 can serve as a buffer space to prevent external force from transmitting. The light shielding portion 223, the polarizer 239, and the substrate 234 are transferred to the liquid crystal layer 238. Moreover, the fixing portion 221 of the touch display panel 230 has its end 221a located directly above the sealant 236. When the external force F2 is transmitted to the fixing portion 221, the fixing portion 221 is the sealant 236 pressed against the display panel 230 instead of the liquid crystal layer 238. The frame rubber 236 is used to absorb the pressure of the external force F2. Therefore, the display device 200 of the present embodiment can prevent the external force F2 applied to the outer frame 220 from causing the display panel 230 to generate a water ripple phenomenon when displayed, or prevent the external force F2 from causing damage to the display panel 230. In addition, the outer frame 220 of the display device 200 of the present embodiment has a light blocking portion 223 extending above the polarizing plate 239, as compared with the outer frame 120' of the conventional liquid crystal display device 100' (as shown in FIG. 2). The stray light 242 emerging from the edge of the display panel 230 can be effectively blocked to avoid light leakage.
