Description of Related Arts
Normally, a device with a display unit such as a screen and a monitor can be arranged to provide a viewing window for a user. Such device can be a TV set, a computer such as a desktop computer, a portable computer, and a tablet computer, a phone, a multimedia player such a MP4, etc. However, currently, these devices are usually provided with only a single display screen. Such device with a single display screen has several disadvantages.
Firstly, when a user prefers a larger viewing screen, the only choice is to purchase another monitor with larger screen or use two or more monitors with a specific monitor software such as “UltraMon” and installation of a multiple monitor graphic card. However, it is inconvenient for the storage and transportation of the large sized display screens, and the cost is also high. Secondly, when a user runs two or more programs or applications on a single screen, he/she will feel inconvenient to change the different viewing windows between different programs or applications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.
Referring to FIGS. 1 to 2 of the drawings, a multiple screen arrangement according to a first preferred embodiment of the present invention is illustrated. The method actually provides a multiple screen arrangement comprises two or more screens. In this preferred embodiment, the multiple screen arrangement comprises two screens, i.e. a first screen 10 and a second screen 20.
Accordingly, in this method, the first and second screens 10 and 20 are arranged to incorporate with a mobile device 40 via a mounting mechanism 30. The mobile device 40 can be a mobile device such as a smart phone, a tablet computer, a laptop computer, and other mobile devices or handheld devices. Alternatively, the first and second screens 10 and 20 may also couple with an immobile device, for example, the mobile device 40 may be embodied as a desktop computer.
More specifically, when the second screen 20 is not in use, the first and second screens 10 and 20 are arranged to overlap with each other. As shown in FIG. 1 of the drawings, the slim first and second screens 10 and 20 are snapped together and sit behind each other to look like it is one screen. Accordingly, in this preferred embodiment of the present invention, the first screen 10 can be embodied as a first screen mounted to the mobile device 40, the second screen 20 can be a second movable screen that can be moved from different states to align with the first screen 10.
According to this preferred embodiment, the first and second screen 10 and 20 are coupled with each via a snapping element 31 of the mounting mechanism 30. As shown in FIG. 2 of the drawings, when the first and second screen 10 and 20 unsnaps, the first and second screen 10 and 20 can be arranged alongside with each other. In other words, the screens 10 and 20 unsnap and can be provided in front of the typing interface/keyboard 41 of the mobile device 40.
In this preferred embodiment, the mobile device is shown to be a laptop computer or a monitor. It is worth mentioning that the mounting mechanism 30 further provides at least one slidable rail 32 for the first and second screens 10 and 20. When the second screen 20 is released from the overlapping state and unsnaps from the first screen 10, the first and second screens 10 and 20 can slide out in opposite direction along the slidable rail 32 on the bottom to center the first and second screens 10 and 20 directly in front of the keyboard 41. The second screen 20 may possibly rotate up to 360 degrees when snapping in position. It is worth mentioning that the two screens 10 and 20 also snap in place and lock in position so they don't slide around when in use. In other words, according to this preferred embodiment, the second screen 20 can unsnap from the rest state to align with the first screen 10, both of the first and second screens 10 and 20 can slide along the slidable rail 32 so that the first and second screens become centered so as to make viewing the multiple screen arrangement easier.
Therefore, two screens 10 and 20 are presented in front of the user, so that the user can view the two screens 10 and 20 at the same time. For example, when the user has to complete two or more tasks or run two or more applications, he may use the first screen 10 for displaying a first application and use the second screen 20 for displaying a second application, so that it is convenient for a user to control all of the tasks and the applications. However, for a conventional device with only a single screen, the user has to shift between different viewing windows in the screen, the user may feel inconvenienced and also errors may easily occur when transposing data.
More specifically, as a further specific example, the two screens 10 and 20 can be arranged for playing games. The first screen 10 displays a first view picture illustrating a first location in the game and the second screen 20 displays a second view picture illustrating a second location in the game, so that the player can control and hold the overall situation of the game.
Accordingly, the second screen 20 can be provided for providing an extra viewing window other than the window provided by the first screen. However, it is worth mentioning that the first and second screens 10 and 20 also can be arranged for enlarging the viewing window. More specifically, when the first screen 10 is not large enough to clearly show the content for the mobile device, the second screen 20 unsnaps to increase the size of the display screen. When not in use, the second screen 20 can be returned to its original position that is overlapped with the first screen 10.
It is worth mentioning that the first and second screens 10 and 20 of the present invention can be the same structure such as LCD or LED monitor, or the second screen 20 can be made to be a flexible or bendable monitor. In addition, when the second screen 20 is overlapped with the first screen 10 in a back to back manner, both of the first and second screens 10 and 20 also can be used to display same content for different users on different sides.
It is worth mentioning that each of the first and second screen 10 and 20 of the present invention can be projection screen or be made from touch screen that enables the user to operate the mobile device or computers electronically linked with the multiple screen arrangement.
In this preferred embodiment, the two screens 10 and 20 are connected to look and function like a single screen until the second screen 20 unsnap from the first screen 10. Accordingly, the unsnapping process can be also achieved by many manners. For example, the two screens 10 and 20 are spring released on the top and the bottom to allow the second screen 20 behind the first screen 10 to slide out and the first screen 10 slides along the other direction to connect in the middle for centered viewing.
When in use, the first screen is turned on or powered on for providing a viewing window, and when the second screen requires use, the second screen is powered by switching on a power button, so that it will not waste power. In addition, when both of the two screens 10 and 20 are in use, the user may choose a screen to be a primary screen. For example, the screens 10 and 20 can be touch screens or projection screens, when the user touches the first screen 10, and the first screen 10 becomes the primary screen that the user is working on, and touch the second screen 20, the primary screen will switch back to the second screen 20.
Providing two screens 10 and 20 will enable the user to control two applications on a single computer or hard drive of another computer through Bluetooth, Mirroring, cable, or network access control such as Wi-Fi, NFC, or mobile network such as 3G network, 4G network, and 5G network. The same keyboard 41 can be used for different mobile devices such as computers and the two screens 10 and 20. As a specific embodiment, when a computer is equipped with the multiple screen arrangement, in wire connection or wireless connection, the present invention allows for mobility to only have to carry one computer to access many computers or applications.
In addition, when one of the first and second screens 10 and 20 is damaged and fails to work, the other one, which may serve as a back-up screen, can be switched on, so that the normal operation of the mobile device 40 will not be affected.
It is worth mentioning that when the multiple screen arrangement of the present invention is embodied as an independent device for coupling with the mobile device 40 via wire connection or wireless connection, it also can be provided with a battery inside so that it can supply its own power or be used as a portable charger or extra battery for the mobile device. Therefore, the multiple screen arrangement coupled with the mobile device 40 via wire connection may also consume the power source of the mobile device 40 to supply its power if required.
