Abstract: An extended screen includes a first display screen, a second display screen, and a third display screen. The second display screen is connected to a top end of the first display screen. The third display screen is connected to a left side edge or a right side edge of the second display screen, so that the first display screen and the third display screen are capable of forming a diagonal shape. When the first display screen and the third display screen form a diagonal shape, one placement position is formed below the third display screen near the first display screen. The placement position is configured for placing a display screen of a computer device. The extended screen includes three display screens, with two display screens arranged transversely above and one display screen arranged below, forming one placement position for placing the display screen of the computer device.

Abstract: An extended display screen includes a display body, a key device. The key device is connected to the display body, and the key device is electrically connected to the display body. By integrating the display body and the key device together, an integrated design of a display device and a keyboard device is achieved, making the device more compact, easy to carry, and simplifying an assembly and use process of the device. At the same time, due to the integrated design, the extended display screen doesn't need to use an external bracket, reducing occupation of desktop space, making the user's working area cleaner and more compact.

Abstract: A posture correcting device includes a supporting body, wherein one end of the supporting body is disposed with a front supporting portion, wherein the supporting body is surrounded along one of the ends to form a wearing cavity, wherein an opening is formed between two ends of the supporting body.

Abstract: A rollable pillow includes an elongated pillow body and a constriction assembly. The pillow body has a first end portion, a second end portion and a main body extended between the first end portion and the second end portion. The pillow body is normally extended in a closed position to form an arc-shaped support structure and able to be rolled up and furled to a furled condition to form a furled spiral structure. The constriction assembly includes an extensible constriction member arranged at a first predetermined position of an outer side of the pillow body and a first joining member arranged at a second predetermined position of the outer side of the pillow body such that the constriction member is able to be extended to connect with the first joining member to constrict the pillow body in the furled condition so as to retain the rollable pillow in the furled spiral structure.

Abstract: A rollable pillow includes a pillow body and a constriction assembly. The pillow body has a first end, a second end and a main body having an inner side and an outer side. The constriction assembly includes a first joining member and a second joining member. The rollable pillow has a furled state. In the furled state, starting from the second end and ending with the first end, the outer side of the main body is rolled up inwardly along the inner side to form a laminated furling structure, wherein the first joining member and the second joining member of the constriction assembly are respectively extended in opposite directions along the outer side of the laminated furling structure and joined together to form a closed constricting structure to constrict the laminated furling structure.
