Description

可撓顯示裝置Flexible display device

本發明是有關於一種顯示裝置，且特別是有關於一種可撓顯示裝置。The present invention relates to a display device, and particularly relates to a flexible display device.

隨著科技進步，市面上開始發展可撓式手機等裝置。為了使此類裝置可以彎折，背蓋可能會是兩片式的設計，兩片結構的交界處對應可撓面板的彎折區(折線處)，以使背蓋不影響面板彎折。With the advancement of science and technology, devices such as flexible mobile phones have been developed on the market. In order to make such a device bendable, the back cover may have a two-piece design, and the junction of the two-piece structure corresponds to the bending area (folding line) of the flexible panel, so that the back cover does not affect the bending of the panel.

此類的可撓面板在彎折時，可撓面板在彎折區(折線處)的背面可能未能被背蓋覆蓋，這使得可撓面板在彎折區的背面不能受到保護。除此之外，由於可撓面板在彎折區的背面外露，易使落塵進入。其後展開可撓面板時，落塵可能會卡在可撓面板與背蓋之間，而使可撓面板受損。When such a flexible panel is bent, the back surface of the flexible panel in the bending area (the fold line) may not be covered by the back cover, which makes the flexible panel unable to be protected at the back surface of the bending area. In addition, since the flexible panel is exposed on the back of the bending area, it is easy for dust to enter. When the flexible panel is unfolded later, the falling dust may get stuck between the flexible panel and the back cover, and damage the flexible panel.

在本發明的一實施例中，當可撓面板彎折時，各凸出部的一末端未被殼體干涉，而使凸出部未彎折。In an embodiment of the present invention, when the flexible panel is bent, one end of each protrusion is not interfered by the shell, and the protrusion is not bent.

在本發明的一實施例中，上述的各凸出部的長度為L公厘，可撓面板的彎折區在對折時的曲率半徑為R公厘，πR>L>πR+20公厘。In an embodiment of the present invention, the length of each of the above-mentioned protrusions is L mm, and the radius of curvature of the bending area of the flexible panel when folded in half is R mm, πR>L>πR+20 mm.

在本發明的一實施例中，上述的兩分支區的這些凸出部中最外側的兩凸出部的最大厚度大於其他凸出部的最大厚度。In an embodiment of the present invention, the maximum thickness of the two outermost protrusions among the protrusions of the above-mentioned two branch regions is greater than the maximum thickness of the other protrusions.

在本發明的一實施例中，上述的兩分支區的這些凸出部中最外側的兩凸出部的最大厚度大於固定區的厚度且小於固定區與可撓面板的厚度和。In an embodiment of the present invention, the maximum thickness of the two outermost protrusions of the protrusions of the two branch areas is greater than the thickness of the fixed area and less than the sum of the thickness of the fixed area and the flexible panel.

在本發明的一實施例中，上述的其中一個分支區的這些凸出部中最外側的兩凸出部的兩末端分別相連於另一個分支區的這些凸出部中最外側的兩凸出部的兩末端。In an embodiment of the present invention, two ends of the two outermost protrusions of the protrusions in one of the above-mentioned branch areas are respectively connected to the two outermost protrusions of the protrusions in the other branch area.

圖1A至圖1C是依照本發明的一實施例的一種可撓顯示裝置的彎折過程的局部剖面示意圖。圖1D是圖1A的可撓顯示裝置的兩可撓支撐件的俯視示意圖。1A to 1C are partial cross-sectional schematic diagrams of a bending process of a flexible display device according to an embodiment of the present invention. FIG. 1D is a schematic top view of two flexible supports of the flexible display device of FIG. 1A.

請參閱圖1A至圖1D，本實施例的可撓顯示裝置100包括可撓面板110、殼體120及兩可撓支撐件130。可撓面板110具有彎折區112。殼體120配置於可撓面板110的背面且適於隨著可撓面板110彎折。殼體120例如是本身具有可撓性的殼體120，在其他未繪示的實施例中，殼體120也可以在對應彎折區112的部位呈現可變形的網狀結構。又或者，殼體120也可以是分離的兩硬殼或兩軟殼。Referring to FIGS. 1A to 1D, the flexible display device 100 of this embodiment includes a flexible panel 110, a housing 120 and two flexible supporting members 130. The flexible panel 110 has a bending area 112. The housing 120 is disposed on the back of the flexible panel 110 and is suitable for bending with the flexible panel 110. The housing 120 is, for example, a housing 120 having flexibility. In other embodiments not shown, the housing 120 may also present a deformable mesh structure at a position corresponding to the bending area 112. Alternatively, the housing 120 may also be two separate hard shells or two soft shells.

兩可撓支撐件130設置於可撓面板110與殼體120之間。可撓支撐件130的材料可以是橡膠、矽膠、編織布或是塑膠等，但不以此為限制。可撓支撐件130分別包括對應於彎折區112且朝向彼此的兩分支區132及連接於兩分支區132兩側且固定於殼體120的兩固定區136。兩固定區136例如是以黏著層140固定於殼體120。The two flexible support members 130 are disposed between the flexible panel 110 and the housing 120. The material of the flexible support 130 can be rubber, silicon rubber, woven cloth, plastic, etc., but it is not limited thereto. The flexible support 130 respectively includes two branch areas 132 corresponding to the bending area 112 and facing each other, and two fixing areas 136 connected to two sides of the two branch areas 132 and fixed to the housing 120. The two fixing areas 136 are fixed to the housing 120 by, for example, an adhesive layer 140.

在本實施例中，兩分支區132適於相對可撓面板110與殼體120移動。因此，當可撓顯示裝置100彎折時，兩可撓支撐件130的兩分支區132位在可撓面板110的彎折區112的背面，以提供支撐與保護。In this embodiment, the two branch areas 132 are suitable for moving relative to the flexible panel 110 and the housing 120. Therefore, when the flexible display device 100 is bent, the two branch areas 132 of the two flexible support members 130 are located on the back of the bending area 112 of the flexible panel 110 to provide support and protection.

如圖1D所示，在本實施例中，各分支區132具有間隔開來的多條凸出部133及位於這些凸出部133之間的多個凹溝135。其中一個分支區132的至少部分的這些凸出部133伸入另一個分支區132的至少部分的這些凹溝135內。As shown in FIG. 1D, in this embodiment, each branch area 132 has a plurality of spaced apart protrusions 133 and a plurality of grooves 135 located between the protrusions 133. At least part of the protrusions 133 of one branch area 132 extends into at least part of the grooves 135 of the other branch area 132.

當可撓面板110尚未彎折時，兩可撓支撐件130的這些凸出部133分別伸入對應的這些凹溝135內，而位於同一平面。如圖1C所示，在本實施例中，當可撓面板110彎折時，可撓支撐件130的凸出部133的末端134抵接於殼體120的內表面，而使凸出部133彎曲。如此一來，這些凸出部133會包覆可撓面板110的彎折區112的背面，以在可撓面板110時對彎折區112的背面提供保護與支撐。當然，可撓面板110彎折時，凸出部133的彎折形式不限於此。When the flexible panel 110 is not yet bent, the protrusions 133 of the two flexible support members 130 respectively extend into the corresponding recesses 135 and are located on the same plane. As shown in FIG. 1C, in this embodiment, when the flexible panel 110 is bent, the end 134 of the protruding portion 133 of the flexible support 130 abuts against the inner surface of the housing 120, so that the protruding portion 133 bending. In this way, the protrusions 133 will cover the back surface of the bending area 112 of the flexible panel 110 to provide protection and support to the back surface of the bending area 112 when the flexible panel 110 is in use. Of course, when the flexible panel 110 is bent, the bending form of the protruding portion 133 is not limited to this.

要說明的是，在本實施例中，可撓支撐件130藉由凸出部133伸入凹槽內的凹凸設計以使凸出部133在移動或變形時能夠沿著凹槽的邊緣移動或變形，較不易往圖1D的上下方向運動。如此，兩可撓支撐件130的兩分支區132較不容易被移動到其他位置(例如是彎折區112以外的位置)，以確保在可撓面板110彎折時能夠對彎折區112提供良好的支撐與保護性。It should be noted that, in this embodiment, the flexible support 130 uses the convex portion 133 to extend into the concave-convex design of the groove so that the convex portion 133 can move or move along the edge of the groove when it moves or deforms. Deformation, it is less easy to move up and down in Figure 1D. In this way, the two branch regions 132 of the two flexible support members 130 are less likely to be moved to other positions (for example, positions other than the bending region 112), so as to ensure that the bending region 112 can be provided when the flexible panel 110 is bent. Good support and protection.

值得一提的是，凸出部133若太長可能在彎折時會擠壓到可撓面板110，凸出部133若太短則無法在彎折時保護整個彎折區112。為了降低上述狀況發生的機率，在一較佳實施例中，如圖1D所示，各凸出部133的長度為L公厘。如圖1C所示，可撓面板110的彎折區112在對折時的曲率半徑為R公厘，πR>L>πR+20公厘。凸出部133的長度藉由上述的設計可以不會擠壓到可撓面板110且可保護到整個彎折區112。It is worth mentioning that if the protruding portion 133 is too long, it may squeeze to the flexible panel 110 during bending, and if the protruding portion 133 is too short, it cannot protect the entire bending area 112 during bending. In order to reduce the probability of occurrence of the above situation, in a preferred embodiment, as shown in FIG. 1D, the length of each protrusion 133 is L mm. As shown in FIG. 1C, the radius of curvature of the bending area 112 of the flexible panel 110 when folded in half is R mm, πR>L>πR+20 mm. The length of the protruding portion 133 can not be squeezed to the flexible panel 110 and can protect the entire bending area 112 through the above-mentioned design.

舉例來說，若曲率半徑R為2公厘時，長度L可為9公厘。若曲率半徑R為3公厘時，長度L可為12公厘。若曲率半徑R為4公厘時，長度L可為16公厘。若曲率半徑R為5公厘時，長度L可為20公厘。當然，曲率半徑R與長度L之間的關係不以此為限制。For example, if the radius of curvature R is 2 mm, the length L can be 9 mm. If the radius of curvature R is 3 mm, the length L can be 12 mm. If the radius of curvature R is 4 mm, the length L can be 16 mm. If the radius of curvature R is 5 mm, the length L can be 20 mm. Of course, the relationship between the radius of curvature R and the length L is not limited to this.

圖2是依照本發明的另一實施例的一種可撓顯示裝置在彎折時的局部剖面示意圖。請參閱圖2，圖2的可撓顯示裝置100’與圖1C的可撓顯示裝置100的主要差異在於，在本實施例中，當可撓面板110彎折時，凸出部133的末端134未被殼體120干涉，凸出部133未被殼體120彎折。在本實施例中，即便凸出部133的末端134未被殼體120干涉而彎折成弧狀，凸出部133仍會覆蓋可撓面板110的彎折區112的背面，而對可撓面板110的彎折區112的背面提供保護與支撐。2 is a schematic partial cross-sectional view of a flexible display device according to another embodiment of the present invention when it is bent. Please refer to FIG. 2. The main difference between the flexible display device 100' of FIG. 2 and the flexible display device 100 of FIG. Without the interference of the housing 120, the protrusion 133 is not bent by the housing 120. In this embodiment, even if the end 134 of the protruding portion 133 is bent into an arc shape without the interference of the housing 120, the protruding portion 133 will still cover the back of the bending area 112 of the flexible panel 110, and will be more flexible. The back surface of the bending area 112 of the panel 110 provides protection and support.

圖3A是依照本發明的另一實施例的一種兩可撓支撐件的俯視示意圖。圖3B是沿著圖3A的A-A’線段的剖面示意圖。圖3C是沿著圖3A的B-B’線段的剖面示意圖。圖3D是應用圖3A的可撓支撐件的可撓顯示裝置在彎折時的局部剖面示意圖。FIG. 3A is a schematic top view of two flexible supports according to another embodiment of the present invention. Fig. 3B is a schematic cross-sectional view taken along the line A-A' of Fig. 3A. Fig. 3C is a schematic cross-sectional view taken along the line B-B' of Fig. 3A. FIG. 3D is a schematic partial cross-sectional view of a flexible display device using the flexible support of FIG. 3A when it is bent.

請參閱圖3A至圖3D，本實施例的可撓顯示裝置100a與圖1A的可撓顯示裝置100的主要差異在於，在圖1A的實施例中，兩分支區132的這些凸出部133的厚度是相同的。在本實施例中，以圖3A來說，兩分支區132a的這些凸出部133、133a中最外側的兩凸出部133a是圖3A中最上方與最下方的這兩個凸出部133a。在本實施例中，兩分支區132a的這些凸出部133、133a中最外側的兩凸出部133a的最大厚度T2(圖3C)大於其他凸出部133的最大厚度T1(圖3B)。Referring to FIGS. 3A to 3D, the main difference between the flexible display device 100a of this embodiment and the flexible display device 100 of FIG. 1A is that, in the embodiment of FIG. The thickness is the same. In this embodiment, taking FIG. 3A as an example, the outermost two protrusions 133a of the protrusions 133, 133a of the two branch regions 132a are the uppermost and lowermost protrusions 133a in FIG. 3A. . In this embodiment, the maximum thickness T2 of the outermost two protrusions 133a of the protrusions 133, 133a of the two branch regions 132a (FIG. 3C) is greater than the maximum thickness T1 of the other protrusions 133 (FIG. 3B).

如圖3C所示，在本實施例中，最外側的凸出部133a的最大厚度T2大於固定區136的厚度T4，而覆蓋到可撓面板110的邊緣。如圖3D所示，當可撓顯示裝置100a彎折時，凸出部133a的末端134a被殼體120干涉，凸出部133a仍會覆蓋到可撓面板110的邊緣。因此，最外側的凸出部133a可防止落塵進入可撓面板110的邊緣。As shown in FIG. 3C, in this embodiment, the maximum thickness T2 of the outermost protrusion 133a is greater than the thickness T4 of the fixed area 136, and covers the edge of the flexible panel 110. As shown in FIG. 3D, when the flexible display device 100a is bent, the end 134a of the protruding portion 133a is interfered by the housing 120, and the protruding portion 133a still covers the edge of the flexible panel 110. Therefore, the outermost protrusion 133a can prevent dust from entering the edge of the flexible panel 110.

此外，在本實施例中，最外側的凸出部133a的最大厚度T2小於固定區136的厚度T4與可撓面板110的厚度T3的和。這樣的設計可避免凸出部133a凸出於可撓面板110的顯示面，以影響彎折狀況。In addition, in this embodiment, the maximum thickness T2 of the outermost protrusion 133a is smaller than the sum of the thickness T4 of the fixed area 136 and the thickness T3 of the flexible panel 110. Such a design can prevent the protrusion 133a from protruding from the display surface of the flexible panel 110 to affect the bending condition.

圖4A是依照本發明的另一實施例的一種兩可撓支撐件的俯視示意圖。圖4B是沿著圖4A的C-C’線段的剖面示意圖。圖4C是沿著圖4A的D-D’線段的剖面示意圖。圖4D是應用圖4A的可撓支撐件的可撓顯示裝置在彎折時的局部剖面示意圖。4A is a schematic top view of two flexible supports according to another embodiment of the present invention. Fig. 4B is a schematic cross-sectional view taken along the line C-C' of Fig. 4A. Fig. 4C is a schematic cross-sectional view along the line D-D' of Fig. 4A. 4D is a schematic partial cross-sectional view of a flexible display device using the flexible support of FIG. 4A when it is bent.

請參閱圖4A至圖4D，在本實施例中，以圖4A來說，兩分支區132b的這些凸出部133、133b中最外側的這些凸出部133b是圖4A中最上方與最下方的這四個凸出部133b。在本實施例中，其中一個分支區132b的這些凸出部133、133b中最外側的兩凸出部133b的兩末端分別相連(例如是以黏著層142連接)於另一個分支區132b的這些凸出部133、133b中最外側的兩凸出部133b的兩末端。Please refer to FIGS. 4A to 4D. In this embodiment, taking FIG. 4A as an example, the outermost protrusions 133b of the protrusions 133, 133b of the two branch regions 132b are the uppermost and the lowermost protrusions in FIG. 4A. The four protrusions 133b. In this embodiment, the two ends of the outermost two protrusions 133b of the protrusions 133, 133b of one of the branch regions 132b are respectively connected (for example, connected by the adhesive layer 142) to these of the other branch region 132b. Both ends of the two outermost protrusions 133b among the protrusions 133 and 133b.

如圖4B所示，以非最外側的凸出部133來說，凸出部133的厚度與固定區136的厚度相同。如圖4C所示，在最外側相連的兩凸出部133b在遠離兩固定區136的部位的厚度T5大於靠近兩固定區136的部位的厚度T6。這樣的設計可以更完整地封閉可撓面板110的邊緣，以避免落塵。As shown in FIG. 4B, taking the protrusion 133 that is not the outermost side as an example, the thickness of the protrusion 133 is the same as the thickness of the fixing area 136. As shown in FIG. 4C, the thickness T5 of the two protruding portions 133 b connected at the outermost side is greater than the thickness T6 of the portion close to the two fixing areas 136. Such a design can more completely close the edge of the flexible panel 110 to avoid dust.

圖5是依照本發明的另一實施例的一種兩可撓支撐件的俯視示意圖。請參閱圖5，在本實施例中，各分支區132c的這些凸出部133c、133d、133e具有多種長度。舉例來說，各分支區132的這些凸出部133c、133d、133e越靠近外側的長度越小。較短的凸出部133c可以讓位給其他的機構，以提供空間。Fig. 5 is a schematic top view of two flexible supports according to another embodiment of the present invention. Referring to FIG. 5, in this embodiment, the protrusions 133c, 133d, and 133e of each branch area 132c have various lengths. For example, the protruding portions 133c, 133d, and 133e of each branch area 132 have a smaller length as they are closer to the outside. The shorter protrusion 133c can give way to other mechanisms to provide space.

當然，在其他實施例中，各分支區132c的這些凸出部133c、133d、133e也可以是越靠近內側的長度越小。或者，凸出部133c、133d、133e的長度也可以與其靠近內外側的位置無關，而視機構上的配置來調整。Of course, in other embodiments, the protruding portions 133c, 133d, and 133e of each branch area 132c may also have a smaller length closer to the inner side. Alternatively, the lengths of the protrusions 133c, 133d, and 133e may be adjusted according to the configuration of the mechanism regardless of their positions close to the inner and outer sides.
