Curved frame body and display module for applying curved frame body

The present invention relates to a frame body, in particular to a curved frame body and a display module using the curved frame body.

The display is divided into a flat display and a curved display. In the case of a large-sized display, since the distance between the center and the edge of the viewer to the flat display is different, it is easy to cause a problem of image distortion due to the distance difference. On the contrary, since the distance from the center of the viewer to the curved display is similar to that at the edge, the problem of image distortion is less likely to occur. Therefore, as the size of the display gradually increases, the display gradually enters a new era of curved surface shapes.

However, since the curved display has at least one dimension of bending deformation, when the frame of the curved display is bent into an L shape, it is affected by the residual bending stress, which causes the L-shaped frame to be unnecessary in other dimensions. Bending deformation. Unexpected bending deformation of the L-shaped frame in other dimensions will result in a gap between the L-shaped frame and the covered display panel, which may impair the appearance and light leakage. Therefore, how to improve the degree of bending deformation of the L-shaped frame applied to the curved display will be one of the problems that the researcher should solve.

The present invention relates to a curved frame body and a display module using the curved frame body, thereby improving the problem of a large degree of bending deformation of the L-shaped frame which is conventionally applied to a curved display.

The curved frame body disclosed in the present invention comprises a curved plate member, a first side plate member and at least one first stress interrupting structure. The curved plate has a curved surface and a first bend on one side of the curved surface Side. The first side panel is coupled to the first curved side of the curved panel. The first stress interrupting structure is located at the first side panel. The width of the first stress-cutting structure away from the first curved side is greater than the width of the first stress-cutting structure near the first curved side.

The display module disclosed in the present invention comprises a curved display panel and at least one curved frame body as described above. The curved frame body is disposed on one side of the curved display panel.

The display module disclosed in the present invention comprises a curved display panel and a curved frame body as described above. The curved frame covers the curved display panel, and the curved display panel is located between the first side panel and the second side panel.

According to the curved frame body and the display module using the curved frame body, at least one stress cut structure is formed on at least one side plate member, and the stress cut structure can damage the unnecessary bending deformation of the curved frame body. The stress is reduced to reduce the degree of unnecessary bending deformation of the curved frame body, thereby beautifying the appearance of the curved frame body.

In addition, the reduced degree of bending deformation of the curved frame body will help to improve the fit between the curved frame body and the curved display panel, thereby reducing the problem of light leakage.

Please refer to Figure 1 and Figure 2. FIG. 1 is a partial perspective view of a display module according to a first embodiment of the present invention. Fig. 2 is a side elevational view of the curved frame body of Fig. 1.

The display module 1 of the embodiment includes a curved frame body 10 and a curved display panel 20. The curved frame body 10 is covered on one side of the curved display panel 20.

The curved frame body 10 is made of metal, and the plurality of curved frame bodies 10 can collectively surround the curved display panel 20. The curved frame body 10 includes a curved plate member 100, a first side plate member 200, and A plurality of first stress interrupting structures 300. The first side panel 200 is coupled to one side of the curved panel 100. These first stress interrupting structures 300 are located on the first side panel 200. The manufacturing process of the curved frame body 10 is as follows.

Please refer to Figures 2 to 4B. Figure 3A is a perspective view of a conventional unmarked curved frame body. Figure 3B is a top plan view of Figure 3A. Fig. 4A is a perspective view of the curved frame body of Fig. 1. Figure 4B is a top plan view of Figure 4A.

As shown in Figures 3A and 3B, a flat member (not shown) is bent by means of stamping or rolling to form a curved frame body 10', which is bent in a single axial direction (e.g., Y-axis). Forming the first side panel 200 and bending along another axial direction (such as the X-axis) to form a curved plate member 100, wherein the first side panel member 200 and the curved panel member 100 have a parallel Y-axis relationship therebetween The line is bent and the cross section of the side section is L-shaped.

In detail, the curved plate member 100 has a curved surface 110. The curved surface 110 is curved along a central axis of curvature (parallel to the X axis), and the curved surface 110 has a first curved side 120 and a second curved side 130 opposite to each other.

The first side panel 200 has an opposite first curved outer edge 210 and a second curved outer edge 220. The first curved outer edge 210 is adjacent to the curved plate member 100 and joined to the first curved side edge 120, and the second curved outer edge 220 is away from the curved plate member 100. In addition, the first side panel 200 has a first surface 230 and a second surface 240 opposite to each other. The second surface 240 faces the curved plate member 100.

The length L2 of the second curved outer edge 220 is greater than the length L1 of the first curved outer edge 210 due to the bending of the first side plate member 200, and the first side plate member 200 has a neutral axis A, and the neutral axis A is introduced. Between the first curved outer edge 210 and the second curved outer edge 220. When the first side panel 200 is bent, the length of the first curved outer edge 210 is shortened, and the length of the second curved outer edge 220 is elongated, wherein the elongation is from negative to positive, and there is a neutral axis with zero elongation. A. In this embodiment, the first side panel 200 If the ratio of the radius of curvature to the width G is 5 or more, it is known by using a look-up table that the neutral axis A and the first curved outer edge 210 and the second curved outer edge 220 are nearly equidistant.

It should be noted that, as shown in FIG. 3B, the stress generated by the bending deformation of the curved frame body 10' may accumulate on the curved plate member 100 and the first side plate member 200 to force the curved plate member 100 and the first The one-side plate member 200 is bent and deformed from the original position (the position of the axis B) in the direction indicated by the arrow a, thereby causing the curved plate member 100 and the first side plate member 200 to have a bending deformation in the X-axis direction and a corresponding maximum bending deformation amount. D1. The generation of the maximum amount of bending deformation causes the curved frame body 10' to deviate from the expected curved frame body. When the maximum bending deformation amount is too large, the curved frame body 10' cannot be assembled with the curved display panel 20.

As shown in FIG. 2, FIG. 4A and FIG. 4B, these first stress interrupting structures 300 are formed on the first surface 230 of the first side panel 200 by means of metal marking. The first stress-cutting structure 300 extends, for example, from the second curved outer edge 220 to the neutral axis A, and the width of the first stress-cutting structure 300 away from the first curved side 120 is greater than the first stress-cutting structure 300 is closer to the first bending The width of the side 120. The first stress interrupting structure 300 is used to break the stress accumulated between the curved plate member 100 and the first side plate member 200 to reduce the degree of bending deformation of the curved plate member 100 and the first side plate member 200 in the X-axis direction. That is, the curved plate member 100 and the first side plate member 200 are displaced toward the original position (axis B) (in the direction indicated by the arrow b) to reduce the original maximum bending shape amount D1 to the current maximum bending deformation. The amount D2. That is, by the arrangement of the first stress-cutting structure 300, the elongation of the second curved outer edge 220 is corrected to reduce the maximum bending shape, and the curved frame body 10 is deviated from the expected curved frame size. Within the allowable range.

In the present embodiment, the first stress interrupting structure 300 is, for example, an inscribed groove that is recessed inward from the first surface 230. The shape of the first stress-cutting structure 300 (engraving groove) is exemplified by a triangle. However, it is not limited thereto. In other embodiments, the shape of the marking groove may also be trapezoidal.

The length of the bottom edge of these first stress-interrupting structures 300 (engraving grooves) is equal to the difference in length between the first curved outer edge 210 and the second curved outer edge 220. In addition, the bottom length W of the first stress-cutting structure 300 (engraving groove) can be designed to be any positive integer less than 0.5 mm, and the number N of the first stress-cutting structure 300 (engraving groove) is calculated as the second song. The length L2 of the outer edge 220 is subtracted from the length L1 of the first curved outer edge 210 by the design value of the length W of the bottom of the first stress interrupting structure 300 (engraving groove), that is, N=(L2-L1)/W .

The curved frame body 10 having the original length (the length in the Y-axis direction) of 1451 mm is actually measured, and the difference in length between the first curved outer edge 210 and the second curved outer edge 220 after rolling and before marking (L2) -L1) is 12 mm and causes the first side panel 200 to produce a maximum bending deformation amount ID1 of 16.3 mm in the X-axis (as shown in Fig. 3B).

Assuming that the preset value of the bottom edge of the first stress-cutting structure 300 (engraving groove) is selected to be 0.5 mm, the number of the first stress-cutting structures 300 (engraving grooves) is 24. When the first first stress-cutting structures 300 (marking grooves) are arranged in a first direction (parallel to the first curved side 120) on the first surface 230 of the first side panel 200, each first stress-cutting structure 300 (engraving groove) may damage the stress accumulated between the curved plate member 100 and the first side plate member 200, so that the maximum bending deformation amount D2 of the curved plate member 100 and the first side plate member 200 in the X-axis direction (such as Figure 4B shows) from the original 16.3 mm to 6.7 mm.

It should be noted that, in the above implementation, the number of the first stress-cutting structures 300 is plural, but not limited thereto. In other embodiments, the number of the first stress-cutting structures 300 may be one, and one single The first stress interrupting structure 300 is disposed at an intermediate position (in the Y-axis direction) of the first side plate member 200. However, the more the number of the first stress-cutting structures 300, the more the first stress-cutting structure 300 The better the effect of force damage.

As shown in FIG. 5, the first stress-cutting structure 300' of the present embodiment is in the form of a perforation. In detail, the first stress-interrupting structure 300' includes a plurality of circular perforations 310'-330'. The circular perforations 310'-330' are arranged from the second curved outer edge 220 toward the first curved outer edge 210, and the diameters d1~d3 of the circular perforations 310'-330' are from the first curved shape. The outer edge 210 to the second curved outer edge 220 are incremented.

As shown in Fig. 6, the difference between this embodiment and the embodiment of Fig. 5 is that the first stress interrupting structure 300' of the present embodiment includes a plurality of square through holes 340' to 370'. It should be noted that the shape of the perforations is not limited to the above-mentioned circular and square shapes. In other embodiments, it may be elliptical, triangular and other forms of quadrilateral, or even each of the first stress-cutting structures 300'. The shape of the perforations is different. The area of each of the perforations has the same area as a circle, that is, has an equivalent diameter equivalent to the circle, and the equivalent diameter of the perforations is increased from the first curved outer edge 210 to the second curved outer edge 220.

Further, the curved plate member 100 has an opening 140. The opening 140 is located between the first curved side 120 and the second curved side 130 to, for example, expose the display surface of the curved display panel. The first side panel 200 and the second side panel 400 are respectively connected to the first curved side 120 and the second curved side 130 of the curved panel 100, and the curved display panel is interposed between the first side panel 200 and the second side panel Between 400.

The curved plate member 100 has a curved surface 110 and a first curved side 120 and a second curved side 130 on opposite sides of the curved surface 110. Further, the curved plate member 100 has an opening 140. The opening 140 is located between the first curved side 120 and the second curved side 130 to, for example, expose the display surface of the curved display panel. The first side panel 200 and the second side panel 400 are respectively connected to the first curved side 120 and the second curved side 130 of the curved panel 100, and the curved display panel is interposed between the first side panel 200 and the second side panel Between 400. The first stress-cutting structures 300c are arranged on the first side panel 200 along the extending direction of the first curved side 120, and the second curved outer edge 220 is broken to form a plurality of discontinuities connected to the first curved side 120. The plate body 2001, and the second stress interrupting structures 500c are arranged on the second side plate member 400 along the extending direction of the second curved side edge 130, and the second side plate member 400 is disconnected. The plurality of plates 4001 joined to the second curved side 130 are broken to break the stress causing unnecessary bending (bending deformation in the XY plane) of the curved plate member 100, the first side plate member 200, and the second side plate member 400.

It should be noted that the difference between the embodiment and the embodiment of FIG. 13 is that the first stress-cutting structure 300c of the embodiment has a slit section 310c and a circular hole section 320c. Similarly, the second stress interrupting structure 500a also has a slit section 510c and a circular hole section 520c.

As shown in Fig. 17, the curved plate member 100 has a thickness T before being bent before forming the curved curved frame body 18. Each of the plates 2001 before the first side plate member 200 is bent has a width D3, D3>T.

In addition, the housing covers at least the first stress interrupting structure 300a and the plate body 2001. Before the first side panel 200 is bent, the upper edge of the first stress interrupting structure 300a (ie, near the first curved side 120) is maintained at a distance D5, D5 < 50T, before the curved surface 110 of the curved panel 100 is bent. The first stress-cutting structure 300a is maintained at a distance D5 before the bending of the curved surface 110 of the curved plate member 100, D5 < 50T. The housing covers at least the first stress interrupting structure 300a and the screw locking holes 250, 450, and the spacing D5 is an exposed area that is not covered by the housing. Taking the 65-inch panel as an example, the T is preferably 0.6 mm, and the spacing D5 is preferably 4T, that is, 2.4 mm. In addition, when the curved frame body 16 and the housing are configured in different colors, the configuration of the spacing D5 can increase the three-dimensional feeling of the curved display and beautify the appearance.

In addition, the above-mentioned stress-cutting structure may be formed on the side plate member before the curved frame bodies 10 to 18 are bent, or may be formed on the side plate member after the curved frame bodies 10 to 18 are bent, and is not limited thereto.

Furthermore, the curved frame bodies 10 to 18 of the above embodiment can be applied to a curved display panel with a fixed curvature or a curved display panel with an adjustable curvature. If the curved frame body 10~18 is applied to the curved surface display panel with adjustable curvature, after the curved frame body 10~18 is assembled with the curved display panel, the curved frame body 10~18 and the curved surface display can also be bent together. The panel adjusts the curvature of the two to make the field of view of the display more in line with the viewer's needs, or to make the application of the curved display more elastic in response to specific advertising design requirements. Sexual and meet the needs.

According to the curved frame body and the display module using the curved frame body, at least one stress cut structure is formed on at least one side plate member, and the stress cut structure can damage the unnecessary bending deformation of the curved frame body. The stress is reduced to reduce the degree of unnecessary bending deformation of the curved frame body, thereby beautifying the appearance of the curved frame body.

In addition, the reduced degree of bending deformation of the curved frame body will help to improve the fit between the curved frame body and the curved display panel, thereby reducing the problem of light leakage.
