The third shading member 300 extends along the Y-Z axis plane and includes a third shading member body 310 and a third shading member extension piece 320. One end 310A of the third shading member body 310 is connected to the other end of the first shading member 100 relative to the second shading member body 210. The third shading member extension piece 320 is at least partially overlapped with the third shading member body 310 and can move along the Y-Z axis plane to extend out of the other end 310B of the third shading member body 310 relative to the first shading member 100. Wherein, the X-axis, Y-axis and Z-axis are perpendicular to each other, and the first shading member 100 can be disposed on the side of the display 600 (see FIG. 1B) (preferably but not limited to the top side of the display).

As shown in the embodiment shown in FIG. 3A, when the user wants to use the light-shielding cover 900 on a display 600' having a larger size, the user can separate the second light-shielding member extension piece 220 and the third light-shielding member extension piece 320 from The second shading member body 210 and the third shading member body 310 are pulled out to a suitable position, that is, the length of the second shading member 200 and the third shading member 300 is increased so that they are at the height of the screen 600' (ie, the second, The length of the three sides) corresponds. In addition, as shown in the embodiment shown in FIGS. 3B and 3C, when the user uses the display in a vertical position, by increasing the length of the second shading member 200 and the third shading member 300 as described above, the shading cover 900 is still applicable . In the above-mentioned embodiment, the first shading member 100 may have different sizes or a retractable design depending on use, design or manufacturing requirements, so as to correspond to the length of the first side of the display.

Based on the above, the light shield 900 of the present invention can be applied to different sizes of displays and/or display usage methods. Users can reduce the need to re-purchase hoods of another size due to screen replacement, and manufacturers can also reduce the specifications of hoods available for users to purchase.

As shown in the embodiment shown in FIG. 2, the second shading member body 210 preferably has a second shading member guide rail 211, and the second shading member extension piece 220 has a second shading member slot 221 that is engaged with the second shading member guide rail 211 , So that the second shading member extension sheet 220 can move along the second shading member guide rail 211 to extend the second shading member body 210. In the preferred embodiment, similarly, the third shading member body 310 preferably has a third shading member guide rail (not shown), and the third shading member extension piece 320 has a third shading member guide rail engaged with the third shading member guide rail. The light-shielding member card slot 321 enables the third light-shielding member extension piece 320 to move along the third light-shielding member guide rail to extend the third light-shielding member body 310.

4, the second shading member guide rail 211 includes a positioning portion 212, the second shading member slot 221 includes a positioning member 222, the second shading member extension piece 220 can move along the second shading member guide rail 211 to make The positioning member 222 is engaged with the positioning portion 212 so that the second shading member extension piece 220 stays at the first position relative to the second shading member body 210. More specifically, the positioning portion 212 includes a cavity, and the positioning member 222 includes an elastic piece. When the positioning member 222 is engaged with the positioning portion 212, the elastic piece extends into the cavity. However, in different embodiments, the positioning portion 212 and the positioning member 222 may be other arrangements with positioning functions, such as elastic balls and cavities.

In the above embodiment, the second shading member extension piece 220 moves along the second shading member guide rail 211 to extend out of the second shading member body 210. However, in different embodiments, the second shading member extension piece 220 can also be guided by a different mechanism to increase the stability when the second shading member body 210 is extended. 5, the side 213 of the second shading member body 210 has a second shading member guide groove 214, and the side edge 224 of the second shading member extension piece 220 is engaged with the second shading member guide groove 214. The second shading member extension piece 220 can move along the second shading member guide groove 214 to extend out of the second shading member body.

In the embodiment shown in FIG. 6, the inner wall 215 of the second shading member guide groove 214 is provided with a plurality of bumps 216, and the side edge 213 (see FIG. 5) of the second shading member extension piece 220 abuts the bumps 216 . In other words, the side edge 213 of the second shading member extension piece 220 will not directly contact and rub against the inner wall 215 of the second shading member guide groove 214. Since the friction force is proportional to the contact area, with the above arrangement, the friction between the side edge 213 and the inner wall 215 when the second shading member extension piece 220 extends out of the second shading member body 210 can be reduced, so that the movement is smoother.

On the other hand, as shown in the embodiment shown in FIG. 7, the second light shielding member 200 and the third light shielding member 300 can further increase the number of extendable elements to increase the length. More specifically, the second shading member 200 further includes a second shading member extension piece 230, which is at least partially overlapped with the second shading member body 210 and the second shading member extension piece 220, and can move along the second side 620 to extend The other end of the second shading member extension piece 220 opposite to the second shading member body 210; the third shading member 300 further includes a third shading member extension piece 330, and the third shading member body 310 and the third shading member extension piece 320 It is at least partially overlapped, and can move along the third side 630 to extend the third light shielding member extension piece 320 relative to the other end of the third light shielding member body 310. Viewed from different angles, the second shading member extension piece 230 can move along the YZ axis plane to extend the second shading member extension piece 220 relative to the other end of the second shading member body 210; the third light shading member extension piece 330 can move along the YZ axis plane The YZ-axis plane moves to extend the other end of the third shading member extension piece 320 relative to the third shading member body 310.
