[0027] The following is combined with Figure 1-7 The utility model is further described in detail with specific embodiments.

[0028] like Figure 1As shown, the utility model provides a portable multi-mode display, including a display body 1, an upper portion of a display back panel 2, a lower portion of a display back panel 3, a display bracket body 4, a display screen driver board protective shell 5, a display screen driver board protective shell opening 6, a display screen driver board protective shell heat dissipation port 7, a data cable and power cable storage device 8, a display lower block 9, a display back panel shaft sliding groove 10, a display shaft 11, a display bracket baffle 12, a display bracket left limit hole 13, a display bracket right limit hole 14, a display upper block 15, a display left block 16, a display right block 17 and a display screen driver board protective shell fixed end 18.

[0029] The display body 1 is the core part of the portable display, which consists of a display screen, a screen driver board, and a protective panel. The display screen can adopt a common LCD screen, an OLED screen, etc., and the present embodiment does not limit the specific type of the screen. The screen driver board is used to receive video signals and drive the display screen to display images. The corresponding driver chip and circuit board can be selected according to the type of screen adopted. In order to effectively protect the screen, an integrated protective panel is set on the front of the display in the present embodiment. The material of the protective panel is a transparent acrylic plate with a thickness of 1 to 2 mm. The size of the protective panel should be slightly larger than the outer dimensions of the display screen, so that the screen is embedded in the opening of the protective panel and a small margin is left around it. The protective panel is fixedly connected to the upper, lower, left and right blocking structures mentioned below, which together play the role of blocking and protecting the screen.

[0030] The display back plate is composed of an upper part 2 and a lower part 3, which are an integrated structure. The display back plate is used to fix the screen, display bracket and other components, and together with the display bracket, it constitutes the main support structure of the display. The display back plate is provided with a B-shaped display back plate shaft sliding groove 10, such as Figure 7 As shown, the display back plate hinge sliding groove 10 is a key structure for switching the display between horizontal and vertical placement modes. The specific structure and principle will be described in detail below.

[0031] The display support body 4 is an irregular long strip structure. The length of the display support body should be less than the length of the display body, and the width should be greater than 1 / 2 of the width of the display body. When the display is not in use, the display support body 4 can be attached to the back plate, acting as a protective cover for the display back plate, protecting the area on the display back plate that is not covered by the display back plate upper part 2, the display back plate lower part 3, the display screen driver board protective shell 5 and other components.

[0032] The display stand body 4 is connected to the display back plate rotation axis sliding groove 10 through the display rotation axis 11. The display stand can rotate 180° around the rotation axis, but due to the structure of the display back plate rotation axis sliding groove and the display stand baffle, the actual rotation angle of the display stand will be limited. Specifically, when the display rotation axis 11 is located in the upper short groove of the display back plate rotation axis sliding groove 10, the display stand body can only rotate a very small angle (no more than 30°) around the rotation axis. At this time, the display stand baffle 12 just touches the upper part 2 of the display back plate, and the display stand body is downward and maintains a stable angle with the display back plate, thereby supporting the display to be placed horizontally, such as Figure 5 When the display shaft 11 is located in the long groove at the bottom of the display back plate shaft sliding groove 10, the display bracket baffle 12 can just pass through the clearance groove of the upper part 2 of the display back plate, and the display bracket body can rotate 90° around the display shaft until it is perpendicular to the display back plate, and the display bracket body supports the display to be placed vertically, as shown in FIG. Figure 6 shown.

[0033] The display bracket body 4 is fixedly connected with two left and right display bracket baffles 12, and the number may be more than two. The length of the display bracket baffle should be greater than the width of the clearance slot of the upper part of the display back plate 2, and form an angle of the threshold angle with the display bracket body 4. Each display bracket baffle is provided with a pair of left and right display bracket limit holes 13 and right limit holes 14 arranged horizontally on the left and right sides, which are used to insert the display shaft 11 to ensure that the display shaft is reliably connected to the display bracket.

[0034] The display screen driver board protective shell 5 is used to accommodate and protect the screen driver board. The size should be determined according to the size of the driver board, and the thickness should be slightly greater than 1.5 times the thickness of the driver board to reserve a certain amount of heat dissipation space. The back of the display screen driver board protective shell is provided with a plurality of display screen driver board protective shell heat dissipation ports 7 for heat dissipation of the driver board chip. The side wall of the display screen driver board protective shell is provided with a display screen driver board protective shell opening 6. The opening size of the display screen driver board protective shell should be able to meet the layout requirements of various interface devices on the driver board to achieve the connection between the driver board and external devices.

[0035] The display screen driver board protective shell is fixedly connected to the protective panel as a whole through the display screen driver board protective shell fixing end 18. The display screen driver board protective shell fixing end can be a snap-fit ​​structure directly extended from the protective panel to achieve snap-fit ​​fixing; or a through hole can be opened on both and connected and fixed by fasteners.

[0036] The data cable and power cable storage device 8 is arranged on the display bracket body 4, and is composed of one or more spiral grooves. A clearance opening is provided at the groove notch, so that the wire harness can easily enter the groove. When the display is working, the wire can be fixed in the groove to increase the aesthetics.

[0037] The lower display block 9, the upper display block 15, the left display block 16 and the right display block 17 are used together to block and fix the display screen. Among them, the lower display block 9 can be formed by extending the front protective panel to the bottom, or fixed by punching and screwing; the upper display block 15 can be formed by extending the front protective panel to the top, or fixed by punching and screwing; the left display block 16 and the right display block 17 use a row of holes of varying numbers to fix the front protective panel to the back panel with screws, and at the same time play the role of blocking the display screen. Two of the four directions must be blocked by punching and screwing, so that the protective panel and the back panel can be fixed as a whole while fixing the display screen.

[0038] The portable display of this embodiment effectively protects the screen from being squeezed and scratched by adopting an integrated protective panel structure. The unique design of the bracket and the back panel sliding groove enables the convenient switching of the display between the horizontal and vertical placement modes. At the same time, the drive board protective shell, wire storage and other structures are compactly integrated on the back panel, which greatly reduces the overall volume of the display and is easy to carry. Compared with the existing technology, this display has a more compact and reasonable structure, richer and more comprehensive functions, and greatly improves portability and practicality.
