[0020] In order to make the purpose, technical solution and effect of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] See also Figure 1-4The utility model provides a portable expansion screen, which includes an expansion screen body 1 and a connector 2. The expansion screen body 1 includes a base 11 and a display panel 12. The display panel 12 is arranged on the front of the base 11, and the four sides of the display panel 12 are arranged close to the four sides of the base 11. Two display areas 120 are provided on the display panel 12. The two display areas 120 can display different pictures respectively. A gap 3 is provided between the two display areas 120. The gap is to better allow users to distinguish where the cutoff point is when projecting different overall pictures or the same overall picture onto the two display areas 120. If there is no gap, it is unclear where the dividing point of the pictures on the two display areas 120 is. The connector 2 is arranged on the base 11 and can The base 11 is installed on the platform through the connecting member 2. The connecting member can be a bracket, a hanging member, a clamping member, a connector or a bolt. In this embodiment, a bracket is preferably used to support the extended screen body on the platform. The platform can be a desktop, a ground, a table, or when it is not a bracket, it can be on a computer monitor, or a support, etc. That is to say, two display areas are provided on the display panel of the extended screen body. The two display areas can display the same picture or different pictures, and a picture can also be spliced and displayed through the two display areas to display an enlarged picture. Then, an extended screen body has three display modes, which is convenient for users to carry and increases the user's usage scenarios and methods.

[0022] In this embodiment, the two display areas 120 are arranged side by side on the display panel, and the aspect ratio of the two display areas 120 is 16:9. The wide side of the display area 120 is arranged close to the long side of the base 11, and the long side of the display area 120 is arranged close to the wide side of the base 11. That is to say, the display area 120 is a horizontal 16:9, which is equivalent to the aspect ratio of a computer monitor, which is convenient for users to watch. When in use, when an overall picture is projected onto the two display areas 120, the extended screen body can be placed horizontally for user viewing. If different overall pictures or the same overall picture needs to be projected onto the two display areas 120 respectively, the extended screen body can be placed vertically, which is convenient for users to watch when watching the picture. Overall, such a structural setting has a better user viewing experience.

[0023] In this embodiment, the display panel 12 includes a first display panel 121 and a second display panel 122, and the two display areas 120 are respectively arranged on the first display panel 121 and the second display panel 122, and the display area 120 is fully covered with the first display panel 121 and the second display panel 122.

[0025] In this embodiment, the connecting member 2 is a U-shaped bracket, which can be rotatably set on the back of the base 11. When the U-shaped bracket is rotated to fit the back of the base 11, a side rod of the U-shaped bracket can cover the connection interface 4. When carrying, the connection interface 4 is protected, which is safer and also prevents the connection interface 4 from being exposed on the back, making the overall appearance cleaner and tidier.

[0026] In this embodiment, the extended screen also includes a control button 5, which is arranged on the side of the boss 13, and the control button 5 and the side of the boss 13 where the connection interface 4 is set are opposite sides. When the U-shaped bracket is rotated to fit the back of the base 11, the other side rod of the U-shaped bracket that covers the connection interface 4 can cover the control button 5. When carried, the control button 5 is protected to prevent the control button 5 from being accidentally touched and damaged, which is safer and also prevents the control button 5 from being exposed on the back, making the overall appearance cleaner and tidier.

[0027] In this embodiment, grooves 21 are provided on both side rods of the U-shaped bracket, and the opening of the groove 21 is facing the base 11. The side edges of the bottom wall of the groove 21 are connected with the side edges of the boss 13, so that there is no gap between the U-shaped bracket and the boss 13, thereby preventing debris from entering the gap and making it difficult to clean. It also further makes the appearance more tidy and enhances the user experience.

[0028] In this embodiment, the two side rods of the U-shaped bracket are gradually narrowed from the connection with the base 11 to the end away from the U-shaped bracket and the two side rods from the base 11, so that the U-shaped bracket is more stable when supporting.

[0029] In this embodiment, the supporting crossbar of the U-shaped bracket is provided with a first foot pad 61, and the bottom edge of the extended screen body 1 is provided with a second foot pad 62. The first foot pad 61 and the second foot pad 62 are both provided to increase friction, making the placement of the extended screen more stable and reducing the wear of the bottom edge.

[0030] In this embodiment, the width of the gap 3 is 0.5-2 mm, preferably 1 mm.
