Unless specifically defined, these terms will not be construed as having idealized or overly formal meanings.

[0045] Please refer to Figure 1 . Figure 1 This is a partial cross-sectional view of a display module 100 according to an embodiment of the present invention. In this embodiment, as... Figure 1 As shown, a display module 100 includes a flexible substrate 110, a matrix structure 120, multiple light sources 130, a fixing plate 150, and multiple telescopic rods 160. The matrix structure 120 at least partially protrudes from the flexible substrate 110 and defines multiple accommodating spaces SP outside the flexible substrate 110. Light sources 130 are disposed on the flexible substrate 110 and located within the accommodating spaces SP, and each of the light sources 130 can actually be a light-emitting diode (LED). The telescopic rods 160 can be extended or shortened respectively and are respectively connected between the flexible substrate 110 and the fixing plate 150. By changing the length of the telescopic rods 160, the flexible substrate 110 can present different bending directions and different curvatures relative to the fixing plate 150 according to the actual situation, such as... Figure 1 As shown.

[0046] Please refer to Figure 2 . Figure 2 yes Figure 1 A partial top view of the display module 100. In this embodiment, the flexible substrate 110 has a plurality of first through-holes H1 configured to allow at least partial passage of the matrix structure 120, and the light sources 130 are arranged in a matrix, with each of the light sources 130 located between at least two adjacent pairs of the first through-holes H1. For example, as Figure 2 As shown, each of the light sources 130 is surrounded by four first perforations H1, that is, the matrix structure 120 that passes through at least part of the first perforations H1 surrounds each of the light sources 130 from four different directions, and defines a corresponding accommodating space SP for each of the light sources 130.

[0047] Please refer to Figure 3 . Figure 3 yes Figure 1 An enlarged cross-sectional view of range A. Specifically, as shown... Figure 3As shown, the flexible substrate 110 further has a hollow portion HP and a plurality of second through holes H2, and the first through hole H1 is also connected to the hollow portion HP. More specifically, the flexible substrate 110 includes an upper sub-substrate 111 and a lower sub-substrate 112. The first through hole H1 is located on the upper sub-substrate 111, and the second through holes H2 are located on the lower sub-substrate 112. The upper sub-substrate 111 and the lower sub-substrate 112 are spaced apart from each other and define the aforementioned hollow portion HP therein. The light source 130 is disposed on the side of the upper sub-substrate 111 away from the lower sub-substrate 112, and the telescopic rod 160 is connected to the side of the lower sub-substrate 112 away from the upper sub-substrate 111.

[0048] Furthermore, such as Figure 3 As shown, the display module 100 includes at least one adjustment member 140. Specifically, the adjustment member 140 includes a plate 141 and a plurality of protrusions 142. The plate 141 of the adjustment member 140 is located in the hollow portion HP between the upper sub-substrate 111 and the lower sub-substrate 112, and the plate 141 is configured to move between the upper sub-substrate 111 and the lower sub-substrate 112. A matrix structure 120 is disposed on one side of the plate 141, and the protrusions 142 are connected to the other side of the plate 141. The protrusions 142 of the adjustment member 140 at least partially pass through the second through-hole H2 of the lower sub-substrate 112.

[0049] More specifically, such as Figure 3 As shown, the matrix structure 120 includes a plurality of light guides 121, which are separated from each other and vertically disposed on the plate 141 of the adjustment member 140. Each of the light guides 121 at least partially passes through one of the corresponding first through holes H1 in the upper sub-substrate 111, and at least two adjacent light guides 121 define one of the corresponding accommodating spaces SP on the side of the upper sub-substrate 111 away from the lower sub-substrate 112.

[0050] Furthermore, each of the light guide portions 121 has at least one light guide surface 121S, and the light guide surface 121S of the light guide portion 121 at least partially faces one of the corresponding light sources 130, so as to produce a light guiding effect on the light source 130. In this embodiment, as Figure 3 As shown, the light-guiding surface 121S of the light guide portion 121 is planar. In other embodiments, depending on the actual situation, the light-guiding surface 121S of each of the light guide portions 121 may have a curvature. For example, the light-guiding surface 121S may be a convex or concave arc surface, and at least partially facing the light source 130.

[0051] As described above, the flexible substrate 110 can adopt different bending directions and different curvatures relative to the fixed plate 150 according to the actual situation. For example, such as Figure 3As shown, the flexible substrate 110 is convex, meaning both the upper sub-substrate 111 and the lower sub-substrate 112 are convex. In this case, the normal directions N of two adjacent light sources 130 away from the flexible substrate 110 are correspondingly far apart, which can easily lead to a decrease in brightness in the corresponding positions of the display module 100 between the two adjacent light sources 130. To maintain the overall brightness uniformity of the display module 100, such as... Figure 3 As shown, the plate 141 of the adjustment member 140 moves toward the upper sub-substrate 111 of the flexible substrate 110 to abut against the upper sub-substrate 111, thereby increasing the height of the light guide portion 121 located between the two adjacent light sources 130 relative to the light source 130, so as to restore the original brightness of the corresponding position.

[0052] In practical applications, the light guide portion 121 of the matrix structure 120 can also play the roles of light absorption and anti-crosstalk. Each of the light guide portions 121 can be made of black plastic material, such as silicone or epoxy resin, but the present invention is not limited thereto.

[0053] Please refer to Figure 4 . Figure 4 yes Figure 1 An enlarged cross-sectional view of range B. Additionally, as... Figure 4 As shown, the flexible substrate 110 is concave, meaning both the upper sub-substrate 111 and the lower sub-substrate 112 are concave. In this case, the normal directions N of two adjacent light sources 130 away from the flexible substrate 110 are correspondingly closer to each other, which can easily lead to an increase in brightness in the corresponding positions of the display module 100 between the two adjacent light sources 130. To maintain the overall brightness uniformity of the display module 100, such as... Figure 4 As shown, the plate 141 of the adjusting member 140 moves toward the lower sub-substrate 112 of the flexible substrate 110 to abut against the lower sub-substrate 112, thereby reducing the height of the light guide portion 121 located between the two adjacent light sources 130 relative to the light source 130, so as to restore the original brightness of the corresponding position.

[0054] To further explain, such as Figure 4 As shown, the upper sub-substrate 111 of the flexible substrate 110 has a surface 111S, and the light source 130 is disposed on the surface 111S of the upper sub-substrate 111. Furthermore, each of the light sources 130 has a thickness TK, and as the plate 141 of the adjusting member 140 abuts against the upper sub-substrate 111 or the lower sub-substrate 112, the height G of each of the light guide portions 121 relative to the surface 111S of the upper sub-substrate 111 is adjustable, and the minimum value of the height G is greater than the thickness TK of the light source 130. That is, even if the plate 141 of the adjusting member 140 abuts against the lower sub-substrate 112 and the height G of the light guide portion 121 relative to the light source 130 decreases, such as... Figure 4As shown, the light guide portion 121 of the matrix structure 120 is still higher than the surface 111S of the sub-substrate 111 than the light source 130.

[0055] In simple terms, when the flexible substrate 110 bends according to the actual situation, the user can increase or decrease the height of the light guide 121 relative to the corresponding light source 130 by moving the adjustment member 140 relative to the flexible substrate 110, thereby offsetting the situation of local overbrightness or underbrightness between the light sources 130 due to the bending of the flexible substrate 110, thus effectively maintaining the overall brightness uniformity of the display module 100.

[0056] In summary, the technical solution disclosed in the above embodiments of the present invention has at least the following advantages: when the flexible substrate bends due to actual conditions, the user can adjust the height of the light guide relative to the corresponding light source by moving the adjustment member relative to the flexible substrate, thereby offsetting the local overbrightness or underbrightness between light sources caused by the bending of the flexible substrate, thus effectively maintaining the overall brightness uniformity of the display module.

[0057] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
