Throughout the specification, the same reference numerals represent the same elements. It should be understood that when an element such as a layer, film, region or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or an intermediate element can also exist. On the contrary, when an element is referred to as being "directly on" or "directly connected to" another element, there is no intermediate element. As used herein, "connection" can refer to physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" can be other elements between two elements.

[0054] In addition, although the terms "first", "second", etc. can be used to describe various elements, components, regions, layers and / or parts in this article, these elements, components, regions, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part.

[0056] Please refer to Figure 1 , which is a schematic diagram of a display module 100 according to an embodiment of an embodiment of the present invention. The display module 100 includes a base 110 , a display panel 120 and a light shielding component 200 .

[0057] The base 110 is used to support other components, such as Figure 1 As shown, the base 110 may be a frame structure covering the display panel 120 , and the material thereof may be plastic, but the present invention is not limited thereto.

[0058] Please also refer to Figure 1 and Figure 2 , Figure 2 It is shown Figure 1 Schematic diagram of a display panel 120 of a display module 100. The display panel 120 is disposed on a base 110, and the display panel 120 includes a panel body 121 and a first polarizer 122.

[0059] like Figure 1 As shown, the edge of the display panel 120 has a warping portion 123, and an outer peripheral surface (not shown) of the display panel 120 is covered by the base 110. In detail, the outer peripheral surface of the display panel 120 is located at the edge of the warping portion 123, and the base 110 completely covers the outer peripheral surface of the display panel 120 to prevent foreign matter from entering the display panel 120 and affecting the performance of the display module 100. Furthermore, the panel body 121 has a lower surface 124, and the first polarizer 122 is disposed on the lower surface 124 of the panel body 121. Further, in the display module 100, the panel body 121 also has an upper surface 125 corresponding to the lower surface 124, and the panel body 121 includes a first substrate 126, a second substrate 127 and a display material layer 128.

[0060] like Figure 2As shown, the second substrate 127 is stacked on the first substrate 126, and the display material layer 128 is located between the first substrate 126 and the second substrate 127, wherein the first substrate 126 includes a lower surface 124, and the second substrate 127 includes an upper surface 125. In detail, the first substrate 126 can be a thin film transistor (Thin-Film Transistor, TFT) glass substrate, the second substrate 127 can be a color filter (Color Filter, CF) glass substrate, and the display material layer 128 can include a liquid crystal display unit (LCD) or an organic light emitting diode display unit (OLED), but the present invention is not limited thereto.

[0061] Furthermore, in the display module 100, the display panel 120 may further include a second polarizer 129, and the second polarizer 129 is disposed on the upper surface 125. Furthermore, the first polarizer 122 and the second polarizer 129 may include a polyvinyl alcohol (PVA) polarizing film, a triacetate cellulose film (TAC) polarizing film or other types of polymer material polarizing films to further control the amount of light passing therethrough, thereby creating different degrees of polarization effects, but the present invention is not limited thereto.

[0062] Please also refer to Figure 1 and Figure 3 , Figure 3 It is shown Figure 1 Schematic diagram of the shading component 200 of the display module 100. The shading component 200 is disposed between the base 110 and the display panel 120, and the shading component 200 includes a buffer member 210, a composite adhesive member 220 and a fixing adhesive member 230.

[0063] The buffer 210 includes a first end 211 and a second end 212, the first end 211 and the second end 212 are located at two opposite sides of the buffer 210, and the second end 212 abuts against the first polarizer 122. In detail, the buffer 210 is sandwiched between the base 110 and the display panel 120, and the edge of the first end 211 of the buffer 210 is aligned with the outer peripheral surface of the display panel 120, wherein the buffer 210 has a first surface 213 and a second surface 214 opposite to each other, the first surface 213 faces the display panel 120, and the second surface 214 faces the base 110. The configuration of the buffer 210 can reduce the strength of the external airflow of the display panel 120 entering the display module 100, thereby improving the dustproof capability of the display module 100, and can provide a buffering force between the base 110 and the display panel 120 to prevent the display panel 120 from being damaged due to external force vibration. In addition, the material of the buffer element 210 can be a material with a high buffering effect such as sponge or foam, but the present invention is not limited thereto.

[0064] The composite adhesive member 220 is disposed on the first surface 213, and the composite adhesive member 220 includes at least two adhesive sections 221. In detail, the composite adhesive member 220 is extended from the first end 211 of the buffer member 210 toward the second end 212, wherein the two side edges of the composite adhesive member 220 are respectively aligned with the first end 211 and the second end 212 of the buffer member 210, and the adhesive force F1 of at least two adhesive sections 221 gradually decreases from the first end 211 to the second end 212. Furthermore, in the display module 100, the number of the adhesive sections 221 is three, and the three adhesive sections 221 are arranged in parallel, and the adhesive force F1 of the adhesive section 221 close to the first end 211 of the buffer member 210 is the largest, and the adhesive force F1 of the adhesive section 221 close to the second end 212 of the buffer member 210 is the smallest among the three adhesive sections 221. In this way, by configuring the adhesive force F1 of the three adhesive sections 221 to gradually decrease in the direction from the first end 211 to the second end 212, a progressive adhesive force configuration can be provided corresponding to the warped portion 123 at the edge of the display panel 120, so that the adhesive section 221 with the maximum adhesive force F1 is first connected to the most severely warped portion of the warped portion 123, and then the other adhesive sections 221 are gradually connected to the portions of the warped portion 123 with different degrees of warping in a step-by-step decreasing adhesive force configuration, so as to gradually offset the warping force F2 of the warped portion 123 of the display panel 120, thereby avoiding light leakage of the display panel 120 and achieving a dust-proof effect at the same time.

[0065] The fixing adhesive member 230 is disposed on the buffer member 210 and is used to connect the buffer member 210 and the base 110. In detail, the fixing adhesive member 230 is located at the second end 212 of the buffer member 210 and is disposed on the second surface 214 of the buffer member 210, so that the adhesive section 221 of the composite adhesive member 220 close to the first end 211 has the maximum adhesive force F1, and the fixing adhesive member 230 is disposed at the second end 212 of the buffer member 210, and the first surface 213 of the first end 211 of the buffer member 210 and the second surface 214 of the second end 212 form a staggered adhesive force distribution, thereby making the display panel 120 more stably connected to the base 110.

[0066] For example Figure 1As shown, the fixing rubber member 230 may not overlap with the first polarizer 122 in a normal direction of the display panel 120, and the length of the buffer member 210 may be equal to the distance from the outer peripheral surface of the display panel 120 to the first polarizer 122 in a normal direction perpendicular to the display panel 120. In this way, the fixing rubber member 230 can be prevented from affecting the polarization effect of the first polarizer 122, and the buffer member 210 can be stably filled between the display panel 120 and the base 110, so as to further enhance the dustproof capability of the display module 100 and effectively prevent light leakage.

[0067] Please refer to Figure 1 , an attachment width of each of the at least two adhesive sections 221 along the direction from the first end 211 to the second end 212 is L1, the adhesive force of at least one of the two adhesive sections 221 is F1, a distance from an edge of at least one of the two adhesive sections 221 to the first polarizer 122 is L2, and a warping force of the warping portion 123 of the display panel 120 is F2, which can satisfy the following condition: L1×F1≤L2×F2. In this way, the adhesive force F1 of each adhesive section 221 can be effectively configured corresponding to the warping force F2 of the warping portion 123, and the adhesive force F1 of at least two adhesive sections 221 can be gradually reduced from the first end 211 to the second end 212. This can not only prevent the adhesive force F1 of each adhesive section 221 from being too large and causing damage to the panel body 121 due to excessive pulling, but also avoid the adhesive force F1 of the adhesive section 221 from being insufficient and affecting the connection and leveling effect of the panel body 121.

[0068] Furthermore, the attachment width of each of the at least two adhesive sections 221 along the direction from the first end 211 to the second end 212 is L1, which can meet the following conditions: 0.2mm≤L1≤2.0mm. In this way, the optimal adhesive configuration of the composite adhesive adhesive 220 can be provided, so that the adhesive change of the composite adhesive adhesive 220 is more gentle, thereby effectively improving the connection and leveling effect of the panel body 121.

[0069] Furthermore, the distance from the edge of at least one of the two adhesive sections 221 to the first polarizer 122 is L2, which can satisfy the following condition: 0.25 mm ≤ L2 ≤ 4.05 mm. Thus, appropriate adhesive forces F1 can be configured for different adhesive sections 221 disposed at different positions corresponding to the warping force F2 of the warping portion 123, so as to further enhance the connection and leveling effect of the panel body 121.

[0078] Thus, by configuring the adhesive force sections 421a, 421b, 421c, 421d, 421e, 421f, and 421g in a progressive manner, and when each adhesive force section satisfies L1×F1≤L2×F2, the adhesive force sections 421a, 421b, 421c, 421d, 421e, 421f, and 421g are in a state of being gradually increased. 1f and the adhesive section 421g can gradually connect the parts with different degrees of warping in the warping portion 323 to effectively offset the warping force F2 of the warping portion 323, and prevent the adhesive force F1 of each of the different adhesive sections from being too large and causing damage to the panel body 321 due to excessive pulling. At the same time, it can avoid the adhesive force F1 of each of the different adhesive sections being insufficient and affecting the connection and leveling effect of the panel body 321, thereby avoiding light leakage of the display panel 320 and achieving a dust-proof effect at the same time.

Anyone skilled in the art can make various changes and modifications 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 following claims.
