Description

[0001] This application is a divisional application. The application number of the parent application is: 201611205541.3, the application date is: December 23, 2016, and the name of the invention is: display device. Technical Field

[0002] The present invention relates to a display device, in particular to a display device with a supporting layer having a special design between the side wall and the surface. Background Art

[0003] With the continuous advancement of display technology, all display panels are developing towards the trend of small size, thin thickness and light weight. Therefore, the mainstream display devices on the market have developed from the previous cathode ray tube to thin displays, such as liquid crystal display panels, organic light emitting diode display panels or inorganic light emitting diode display panels. Among them, thin displays can be applied in many fields, including mobile phones, laptops, video cameras, cameras, music players, mobile navigation devices, televisions and other display panels used in daily life, most of which use these display panels.

[0004] Although thin displays have greatly reduced the thickness and weight of display devices, with the development of technology, the requirements for thinner and lighter electronic products are constantly increasing. Therefore, the glass substrates of display devices are developing from thicker glass substrates to thinner substrate materials.

[0005] However, when a display device is formed by using a thinner substrate material as a supporting layer, if a display component is directly formed thereon, the supporting layer is often not rigid enough and cannot be directly used in the existing panel process.

[0006] In view of this, there is still a need to develop a display device that can avoid the problem of the support layer being difficult to separate from the carrier due to the overflow of the adhesive layer through a special structural design. Summary of the invention

[0007] The main object of the present invention is to provide a display device, which is a display device having a special design between the side wall and the surface of the support layer.

[0008] In one embodiment of the present invention, the display device includes: a supporting layer having a first surface, a second surface and a first side wall, wherein the first surface and the second surface are located on opposite sides of the supporting layer, the first side wall connects the first surface and the second surface, the first surface and the first side wall have a first angle, and the second surface and the first side wall have a second angle; an adhesive layer disposed on the supporting layer; a substrate layer disposed on the adhesive layer; and a plurality of thin film transistors disposed on the substrate layer; wherein the first angle and the second angle are greater than 0 degrees and less than 180 degrees, and the first angle is not equal to the second angle.

[0009] In another embodiment of the present invention, a display device includes: a substrate, including: a support layer, having a first surface, a second surface and a first side wall, wherein the first surface and the second surface are located on opposite sides of the support layer, the first side wall connects the first surface and the second surface, the first surface and the first side wall have a first angle, and the second surface and the first side wall have a second angle; an adhesive layer, disposed on the support layer; a base material layer, disposed on the adhesive layer, wherein the base material layer includes a central portion, a first A bending portion and a second bending portion, the first bending portion is adjacent to the central portion and the adjacent portion is defined as a first bending line, the second bending portion is adjacent to the central portion and the adjacent portion is defined as a second bending line, and the first bending portion is bent along the first bending line toward the supporting layer, and the second bending portion is bent along the second bending line toward the supporting layer; and a plurality of thin film transistors are arranged on the substrate layer; wherein the first angle and the second angle are greater than 0 degree and less than 180 degrees, and the first angle is not equal to the second angle.

[0010] Among them, the side wall of the support layer and the first and second surfaces connected to the side wall have a special angle design, which can prevent the adhesive layer on the support layer from overflowing to the bottom of the support layer during the production process of the display device. In particular, when the display device of the present invention is a flexible display device, a carrier is usually set at the bottom of the support layer during the production process, and the carrier is removed after the display device is prepared. Therefore, if the support layer does not have the aforementioned special angle design, when the adhesive layer on the support layer overflows to the bottom of the support layer, the overflowed adhesive layer will make it difficult to separate the support layer from the carrier; therefore, the display device of the present invention can avoid the problem of the overflowed adhesive layer causing the support layer and the carrier to be difficult to separate by making the support layer have the aforementioned special angle design. .

[0038] Figure 1 The cross-sectional schematic diagram of a display device according to an embodiment of the present invention. The preparation method of the display device according to the present embodiment is roughly as follows. First, a support layer 11 is provided, which can be made of a substrate material such as glass, plastic, a flexible material, a film, etc.; in the present embodiment, the material of the support layer 11 can be polyethylene terephthalate (PET) or polyethylene naphthalate (PEN). Then, an adhesive layer 12 is formed on the support layer 11, which can be formed by a colloid. Next, a substrate layer 13 is formed on the adhesive layer 12, which can be made of a substrate material such as plastic, a flexible material, a film, etc.; in the present embodiment, the substrate layer 13 is polyimide (PI). Finally, a plurality of thin film transistors 14 are formed on the substrate layer 13. In addition, although not shown, in the display device of this embodiment, after forming the thin film transistor 14, a display layer, another adhesive layer, a barrier layer, and a polarizing film can be formed in sequence; and other functional layers can be formed between layers as required.

[0039] After the above processes, the display device of the present embodiment can be manufactured. According to the type of the display layer, the display device of the present embodiment can be various types of display devices. For example, if the display layer is a liquid crystal layer, a liquid crystal display device (LCD) can be obtained; if the display layer is an organic light emitting diode component layer, an organic light emitting diode display device (OLED) can be obtained; and if the display layer is an inorganic light emitting diode component layer, a micro-LED display device (micro-LED display) can be obtained.

[0040] like Figure 1 As shown, the display device of this embodiment includes: a substrate 1, including: a support layer 11, having a first surface 111, a second surface 112 and a first side wall 113, wherein the first surface 111 and the second surface 112 are located on opposite sides of the support layer 11, the first side wall 113 connects the first surface 111 and the second surface 112, the first surface 111 and the first side wall 113 have a first angle θ1, and the second surface 112 and the first side wall 113 have a second angle θ2; an adhesive layer 12, disposed on the support layer 11; a base material layer 13, disposed on the adhesive layer 12; and a plurality of thin film transistors 14, disposed on the base material layer 13. The first angle θ1 and the second angle θ2 are greater than 0 degrees and less than 180 degrees, and the first angle θ1 is not equal to the second angle θ2.

[0041] In the display device of this embodiment, the substrate layer 13 can be made of substrate materials such as plastic, flexible material, film, etc.; therefore, the display device of this embodiment is a flexible display device. Similarly, as mentioned above, depending on the type of display layer, the display device of this embodiment can be a variety of different types of display devices, such as a flexible liquid crystal display device, a flexible organic light emitting diode display device, or a flexible micro light emitting diode display device. When making a flexible display device, a carrier plate 2 (such as a substrate 2) is usually set at the bottom of the support layer 11. FIG. 2A to FIG. 2C When the first angle θ1 between the first surface 111 and the first side wall 113 of the support layer 11 is not equal to the second angle θ2 between the second surface 112 and the first side wall 113, the adhesive layer 12 on the support layer 11 can be prevented from overflowing and flowing to the bottom of the support layer 11 during the production of the display device, thereby making it difficult to remove the support layer 2.

[0042] For example, when the first angle θ1 between the first surface 111 of the support layer 11 and the first side wall 113 and the second angle θ2 between the second surface 112 and the first side wall 113 are equal and both are 90 degrees, the adhesive layer 12 easily flows along the first side wall 113 to the bottom of the support layer 11 and adheres to the carrier 2; and in a more serious case, the overflowed adhesive layer 12 flows to the interface between the support layer 11 and the carrier 2. In this case, when the preparation of the flexible display device is completed, because the adhesive layer 12 covers the entire first side wall 113 of the support layer 11 and is further adhered to the carrier 2, it is not easy to separate the carrier 2 from the support layer 11.

[0043] However, when the first angle θ1 of the display device is not equal to the second angle θ2, the aforementioned problem can be avoided. FIG. 2A to FIG. 2C 1 is a cross-sectional schematic diagram of a display device having different supporting layers 11 according to different embodiments of the present invention; for the convenience of explanation, other layers above the adhesive layer 12 are omitted.

[0044] At Figure 2A In the figure, the first side wall 113 of the support layer 11 is an irregular side wall, wherein the first angle θ1 and the second angle θ2 are not equal and are both obtuse angles. When the adhesive layer 12 overflows, since the first side wall 113 is an irregular side wall, the overflowed adhesive layer 12 is less likely to flow along the first side wall 113 to the bottom of the support layer 11 and adhere to the carrier 2. Therefore, after the flexible display device is manufactured, the support layer 11 can be easily separated from the carrier 2.

[0045] At Figure 2B In the embodiment, the first angle θ1 and the second angle θ2 of the support layer 11 are not equal and the first angle θ1 is an acute angle while the second angle θ2 is an obtuse angle. When the adhesive layer 12 overflows, since the first side wall 113 is an inclined side wall, the overflow path of the overflow adhesive layer 12 on the first side wall 113 can be increased, so that the overflow adhesive layer 12 is less likely to reach the bottom of the support layer 11 and adhere to the carrier 2. Therefore, after the production of the flexible display device is completed, the support layer 11 can be easily separated from the carrier 2.

[0046] In addition, Figure 2C In the embodiment, the first angle θ1 and the second angle θ2 of the support layer 11 are not equal and the first angle θ1 is an obtuse angle while the second angle θ2 is an acute angle. When the adhesive layer 12 overflows, since the first side wall 113 is an inclined side wall and the inclined side wall is similar to the inverted trapezoidal side wall structure, when the adhesive layer 12 overflows, the overflowed glue is not easy to flow along the first side wall 113, but will be suspended on the carrier 2; and in some cases, such as Figure 2CIn the situation shown, the overflowing adhesive layer 12 will drip onto the carrier 2. However, no matter whether the overflowing adhesive layer 12 is suspended on the carrier 2 or drips onto the carrier 2, the adhesive layer 12 attached to the supporting layer 11 is not easy to reach the bottom of the supporting layer 11 and adhere to the carrier 2. Therefore, after the flexible display device is manufactured, the supporting layer 11 can be easily separated from the carrier 2.

[0047] Therefore, if FIG. 2A to FIG. 2C As shown, in the display device of this embodiment, by making the support layer 11 have the aforementioned special angle design, that is, when the first angle θ1 between the first surface 111 of the support layer 11 and the first side wall 113 is not equal to the second angle θ2 between the second surface 112 and the first side wall 113, the problem of the support layer 11 and the carrier 2 being difficult to separate due to the overflowing adhesive layer 12 can be avoided. FIG. 2A to FIG. 2C This is only an illustrative embodiment, and the present invention is not limited thereto. The support layer 11 may have FIG. 2A to FIG. 2C The different shapes shown are sufficient as long as the aforementioned first angle θ1 is not equal to the second angle θ2.

[0048] In addition, if Figure 1 As shown, in the display device of this embodiment, the support layer 11 has a first thickness T1, the adhesive layer 12 has a second thickness T2, and the substrate layer 13 has a third thickness T3. The third thickness T3 is less than the first thickness T1, and the second thickness T2 is less than the first thickness T1. Therefore, among the support layer 11, the adhesive layer 12 and the substrate layer 13, the support layer 11 has the largest thickness; the reason is that the support layer 11 needs to bear the adhesive layer 12, the substrate layer 13 and other layers, so it needs to have the largest thickness to provide appropriate bearing strength.

[0049] In addition, in the display device of this embodiment, the third thickness T3 of the substrate layer 13 is smaller than the second thickness T2 of the adhesive layer 12. The reason is that the substrate layer 13 may need to be bent in the future, and is a flexible substrate layer 13; therefore, the substrate layer 13 must have a thinner thickness to provide better ductility. However, the main function of the adhesive layer 12 is to attach the substrate layer 13 to the support layer 11, so it must have a certain thickness to provide sufficient adhesion.

[0050] like Figure 1As shown, in the display device of this embodiment, the adhesive layer 12 has a first protrusion 121, and the first protrusion 121 is protruding from the first side wall 113 of the support layer 11; wherein the first protrusion 121 is a portion of the adhesive layer 12 and the support layer 11 (particularly, the second surface 112 of the support layer 11) that does not overlap. In addition, the substrate layer 13 has a second protrusion 131, and the second protrusion 131 is protruding from the first side wall 113 of the support layer 11; wherein the second protrusion 131 is a portion of the substrate layer 13 and the support layer 11 (particularly, the second surface 112 of the support layer 11) that does not overlap. If it is defined that the first side wall 113 and the second surface 112 have a first edge 1121 intersecting, the first protrusion 121 is the adhesive layer 12 protruding from the first edge 1121, and the second protrusion 131 is the substrate layer 13 protruding from the first edge 1121. If the virtual interface (shown by the dotted line) passing through the first edge 1121 and perpendicular to the second surface 112 is used as a reference, the area of ​​the adhesive layer 12 that does not overlap with the support layer 11 and is located outside the virtual interface is the first protrusion 121, and the area of ​​the substrate layer 13 that does not overlap with the support layer 11 and is located outside the virtual interface is the second protrusion 131. In addition, the first protrusion 121 of the adhesive layer 12 can also selectively cover a portion of the first side wall 113 of the support layer 11, such as Figure 3A and Figure 3B When the substrate layer 13 is bendable or larger than the support layer 11 , the first protrusion 121 of the adhesive layer 12 can help improve the adhesion between the support layer 11 and the substrate layer 13 .

[0051] Figure 3A and Figure 3B Schematic diagram of the cross section of the adhesive layer and the substrate layer of the display device of the present invention with different embodiments. Figure 3A and Figure 3B In the figure, other layers above the substrate layer 13 are omitted and not shown. Figure 3A In the embodiment, the substrate layer 13 is larger than the support layer 11; Figure 3B In the embodiment, the substrate layer 13 is larger than the support layer 11 and is also a bendable substrate layer. Figure 3A and Figure 3B In the embodiment, the substrate layer 13 has a second protrusion 131 that does not overlap with the second surface 112 of the support layer 11. Therefore, when the adhesive layer 12 has a first protrusion 121, and the first protrusion 121 is larger than the support layer 11 and does not overlap with the second surface 112 of the support layer 11, the first protrusion 121 can help the adhesion between the second protrusion 131 of the substrate layer 13 and the support layer 11. In particular, the first protrusion 121 of the adhesive layer 12 can also cover part of the first side wall 113 of the support layer 11, which can further enhance the adhesion between the second protrusion 131 of the substrate layer 13 and the support layer 11. Here, Figure 3Aand Figure 3B This is only an example of an embodiment for illustration, and the present invention is not limited thereto. The support layer 11, the adhesive layer 12 and the substrate layer 13 may have the same Figure 3A and Figure 3B Different shapes shown.

[0052] In the display device of the present invention, the substrate layer can be made of substrate materials such as plastic, flexible material, film, etc. Therefore, the display device of the present invention is a flexible display device. Figures 4 to 6 In the figure, possible bending states of the substrate layer of the display device of different embodiments of the present invention are provided.

[0053] At Figures 4 to 6 In the embodiment, the substrate layer 13 includes a central portion 132 and a first bending portion 133. The first bending portion 133 is adjacent to the central portion 132 and the adjacent portion is defined as a first bending line L1. In addition, the substrate layer 13 may also selectively include a second bending portion 134, and the second bending portion 134 is adjacent to the central portion 132 and the adjacent portion is defined as a second bending line L2. When the substrate layer 13 includes both the first bending portion 133 and the second bending portion 134, the extension directions of the first bending line L1 and the second bending line L2 may be the same or different. Figure 4 and Figure 6 In the illustrated embodiment, the first bending line L1 and the second bending line L2 extend in different directions, so the first bending line L1 or its extending direction may intersect with the second bending line L2 or its extending direction. In addition, the first bending portion 133 has a first side 1331, which intersects with the first bending line L1 or its extending direction; and the second bending portion 134 has a second side 1341, which intersects with the second bending line L2 or its extending direction.

[0054] At Figure 4 In the embodiment, the first side edge 1331 and the second side edge 1341 are formed by two cutting processes to form a right angle cut; Figure 5 In the embodiment, the first side edge 1331 and the second side edge 1341 are formed by an oblique cutting angle formed by a cutting process. Figure 4 and Figure 5In the embodiment, whether it is a right-angle cut formed by two cutting processes or an oblique cut formed by one cutting process, before the first bending portion 133 and the second bending portion 134 are bent, the angle θ3 between the first side 1331 and the second side 1341 can be between 70 degrees and 250 degrees (for example, between 90 degrees and 180 degrees); therefore, the angle θ4 formed between the first side 1331 and the first bending line L1 and the angle θ5 formed between the second side 1341 and the second bending line L2 can also be between 10 degrees and 100 degrees (for example, between 45 degrees and 90 degrees), and the sum of the angles θ3, θ4 and θ5 does not exceed 270 degrees. Figure 4 In the figure, the angle θ3 is 90 degrees, and the angles θ4 and θ5 are also 90 degrees; Figure 5 , the angle θ3 is 180 degrees, and the angles θ4 and θ5 are 45 degrees; however, the present invention is not limited thereto.

[0055] At Figure 4 and Figure 5 In the embodiment, the first side 1331 and the second side 1341 are both straight side edges. However, the first side 1331 and the second side 1341 are not limited to straight side edges, but may be curved side edges. Figure 6 As shown, the first side edge 1331 and the second side edge 1341 are formed by an arc-shaped cutting angle formed by a cutting process; Figure 6 In the embodiment, the first side edge 1331 and the second side edge 1341 are curved side edges. Figure 6 In the implementation mode of the arc-shaped cutting angle, a tangent can be obtained from the intersection point where the first side 1331 intersects with the first bending line L1 or its extension direction, and the angle θ4 between the first side 1331 and the first bending line L1 is the angle obtained between the first bending line L1 or its extension direction and the aforementioned tangent; similarly, another tangent can be obtained from the intersection point where the second side 1341 intersects with the second bending line L2 or its extension direction, and the angle θ5 between the second side 1341 and the second bending line L2 is the angle obtained between the second bending line L2 or its extension direction and the aforementioned other tangent.

[0056] At Figures 4 to 6 After the cutting process, the first bending portion 133 and the second bending portion 134 can be bent toward the support layer 11 along the first bending line L1 and the second bending line L2, respectively. Figure 3B shown; Figure 3B The second protrusion 131 shown is equivalent to Figures 4 to 6 The first bending portion 133 and the second bending portion 134 shown in FIG. Figure 4 The right angle cut shown, such as Figure 5 The bevel cut shown or Figure 6The arc cut angle shown in the figure can form the first bending portion 133 and the second bending portion 134. Therefore, the first bending portion 133 and the second bending portion 134 can be bent simultaneously along two different and intersecting first bending lines L1 and second bending lines L2, thereby overcoming the problem that the adjacent first bending portions 133 and second bending portions 134 cannot be bent simultaneously.
