[0033] This utility model proposes a portable display.

[0034] In the embodiments of this utility model, such as Figures 1 to 9 As shown, the portable display includes a display screen 10 and a main control device 20. The display screen 10 has a screen assembly 11, a connection line 15 connected to the screen assembly 11, and a first connector 12 connected to the connection line 15. The main control device 20 is magnetically connected to the display screen 10 for detachable installation. The main control device 20 has a control circuit, a power supply circuit connected to the control circuit, and a second connector 21 connected to the control circuit. The second connector 21 is electrically connected to the first connector 12 when the main control device 20 is magnetically fixed to the display screen 10.

[0035] Specifically, the display screen 10 includes a housing 14, and a screen assembly 11 is mounted on the housing 14. The screen assembly 11 is used to display images and can be a liquid crystal display, OLED display, or Mini LED display, etc. The connecting lines 15 can be flexible circuit boards. The specific circuit composition of the power supply circuit and control circuit can refer to the prior art, and will not be described in detail here. Since the main control device 20 and the display screen 10 are set separately, the power supply circuit and control circuit are both located in the main control device 20. Only the screen assembly 11, the first connector 12, and the connecting lines 15 need to be set on the display screen 10, which simplifies the structure of the display screen 10 and reduces its thickness. Compared with the overall storage, the display screen 10 is thinner and lighter, making it easier to store in gaps, while the main control device 20 has a smaller overall size and can be stored in corner spaces.

[0036] The main control device 20 has a power interface 241 and a projection interface 242. The power interface 241 is used to connect a power adapter to power the portable display. The projection interface 242 is used to connect electronic devices such as mobile phones and computers. That is, when the main control device 20 and the display screen 10 are magnetically connected, and the first connector 12 and the second connector 21 are connected, and the projection interface 242 is connected to an electronic device, the display screen 10 can be used as an extended display screen for the electronic device. Of course, in other embodiments, only one interface (such as a Type-C interface) can be provided, and power supply and data transmission can be achieved through a single interface.

[0037] This utility model's technical solution sets the power supply circuit and control circuit in the main control device 20, and separates the main control device 20 from the display screen 10. This reduces the number of electrical components on the display screen 10, thereby reducing the space occupied by the power supply circuit and control circuit on the display screen 10, reducing the thickness of the display screen 10, and achieving a thinner and lighter design for the display screen 10. Moreover, the main control device 20 can be removed from the display screen 10 and stored separately, greatly improving the portability of the portable display.

[0038] In some embodiments, the first connector 12 includes a plurality of conductive contacts 121, and the second connector 21 includes a plurality of spring pins 211, with each spring pin 211 corresponding to one of the conductive contacts 121. Specifically, the conductive contacts 121 are sheet-like metals and are connected to the connection lines 15. This allows the first connector 12 to be thinner, reducing the space occupied by the first connector 12 in the thickness direction of the display screen 10, which is beneficial for further reducing the thickness of the display screen 10. The second connector 21 uses spring pins 211, which, when the main control device 20 is magnetically attached to the display screen 10, can press against the conductive contacts 121, ensuring a stable connection between the first connector 12 and the second connector 21. Of course, in other embodiments, the first connector 12 includes a plurality of conductive sockets, and the second connector 21 has a plurality of conductive pins, each conductive pin corresponding to one conductive socket.

[0039] In some embodiments, the second connector 21 further includes a mounting plate 212 and a ribbon cable connector 213 disposed on the mounting plate 212. The ribbon cable connector 213 is electrically connected to the control circuit, and a plurality of spring pins 211 are mounted on the side of the mounting plate 212 opposite to the ribbon cable connector 213. Specifically, a circuit board 26 can be used as the mounting plate 212, and the ribbon cable connector 213 is connected to the control circuit through a flexible circuit board. In this way, the plurality of spring pins 211 are integrated on the mounting plate 212, so that the mounting plate 212 and the plurality of spring pins 211 form a module, which is more convenient when assembling the main control device 20, and at the same time ensures that the spring pins 211 are reliably installed.

[0040] In some embodiments, the mounting part 13 is provided with a foolproof structure, and the main control device 20 has a mating part adapted to the foolproof structure, so that the main control device 20 and the mounting part 13 have a unique mating, which can prevent the main control device 20 and the display screen 10 from being installed incorrectly.

[0041] Optionally, the foolproof structure includes a first socket 131 and a second socket 132, which are spaced apart circumferentially along the first connector 12. The inner diameter of the first socket 131 is larger than that of the second socket 132. The mating part has a first protrusion 231 that mates with the first socket 131 and a second protrusion 232 that mates with the second socket 132. Specifically, the outer diameter of the first protrusion 231 is larger than that of the second protrusion 232. The main control device 20 and the mounting part 13 are in the correct position only when the first protrusion 231 is inserted into the first socket 131 and the second protrusion 232 is inserted into the second socket 132. Both the first socket 131 and the second socket 132 are round holes, and both the first protrusion 231 and the second protrusion 232 are cylindrical. This configuration effectively prevents fooling while simplifying the structure of the foolproof structure and the mating part. By setting the first socket 131 and the second socket 132 in the foolproof structure, the protruding structure on the display screen 10 can be avoided, making it easier for users to store and carry.

[0042] Of course, in other embodiments, a strip groove can be provided in the foolproof structure, and a strip rib adapted to the strip groove can be provided in the mating part; or a trapezoidal groove or a semi-circular groove or other non-rotationally symmetric graphic groove can be provided in the foolproof structure, and the mating part can be adapted to the non-rotationally symmetric graphic groove.

[0043] In some embodiments, the main control device 20 has a power interface 241, a projection interface 242, and multiple expansion interfaces 242. The power interface 241 is electrically connected to the power circuit, and the projection interface 242 and the multiple expansion interfaces 242 are electrically connected to the control circuit. Specifically, the power interface 241 is used to connect a power adapter, which can be a Type-C interface or other types of interfaces. The projection interface 242 is used to connect electronic devices, which can be a Type-C interface or an HDMI interface, etc. When the projection interface 242 is a Type-C interface, power transmission between the projection interface 242 and the electronic device can also be achieved through the projection interface 242. The expansion interfaces 242 can be USB-A interfaces, Type-C interfaces, or other data transmission interfaces, used to connect peripherals such as mice, keyboards, and USB flash drives, and can also be used to charge other electronic devices (such as mobile phones). By providing multiple expansion interfaces 242, it is convenient to connect peripherals and the ease of use can be improved.

[0044] In some embodiments, the main control device 20 is provided with a screen 25, which is electrically connected to the control circuit. When in use, the screen 25 can display the working status of the main control device 20 (e.g., display the input / output power of the power supply circuit, or when a temperature sensing element is provided in the main control device 20, the screen 25 can display temperature information) or display images, etc.

[0045] In some embodiments, the first connector 12 and the screen 25 are respectively located at opposite ends of the main control device 20, while the power interface 241, the projection interface 242, and multiple expansion interfaces 242 are all located around the main control device 20. This allows for a greater number of expansion interfaces 242 to be provided around the main control device 20, enhancing its functionality. Of course, in other embodiments, the screen 25 can also be located around the main control device 20.

[0046] In some embodiments, a mounting portion 13 is provided on the back of the display screen 10, a first connector 12 is disposed on the mounting portion 13, the screen 25 is located on the top of the main control device 20, and a second connector 21 is located on the bottom of the main control device 20. The bottom of the main control device 20 is magnetically connected to the mounting portion 13. During use, the main control device 20 is hidden on the back of the display screen 10, which reduces the possibility of the user touching the main control device 20 and ensures stable data transmission during use. It also keeps the front of the display screen 10 clean, preventing power cords and data cables from being exposed on the front of the display screen 10 and affecting user operation. Of course, in other embodiments, the mounting portion 13 can also be located on the side of the display screen 10.

[0047] In some embodiments, the main control device 20 includes a housing 22 and a plurality of circuit boards 26 disposed within the housing 22. The bottom wall 221 of the housing 22 is provided with a magnetic attraction structure and a second connector 21. The magnetic attraction structure is magnetically connected to the display screen 10. The plurality of circuit boards 26 are arranged at intervals in a direction perpendicular to the bottom wall 221 of the housing 22. Specifically, the circuit boards 26 are approximately parallel to the bottom wall 221 of the housing 22. This arrangement allows for a smaller width of each individual circuit board 26, thereby reducing the width of the main control device 20 and facilitating a reduction in the size of the main control device 20. At least one of the magnetic attraction structure and the mounting portion 13 is provided with a permanent magnet. For example, the magnetic attraction structure has a permanent magnet, and the mounting portion 13 is provided with a ferromagnetic metal (such as iron, cobalt, nickel, etc.); or the mounting portion 13 has a permanent magnet, and the magnetic attraction structure is provided with a ferromagnetic metal; or both the magnetic attraction structure and the mounting portion 13 have permanent magnets, with opposite magnetic poles of the permanent magnets in the magnetic attraction structure and the mounting portion 13 facing each other.

[0048] Optionally, the circuit board 26 containing the control circuit is adjacent to the second connector 21, and the circuit board 26 containing the power supply circuit is located on the side of the circuit board 26 containing the control circuit away from the second connector 21. This facilitates the connection between the second connector 21 and the control circuit and can reduce the wiring inside the main control device 20.

[0049] In some embodiments, the main control device 20 includes a clock chip and a battery that powers the clock chip. The clock chip is electrically connected to the control circuit. The portable display has an always-on display mode, in which the screen assembly 11 displays the time. Specifically, the battery powers only the clock chip, ensuring its continuous operation even when the portable display is powered off, thus guaranteeing time accuracy. In the always-on display mode, the portable display is powered by a power adapter or electronic device, and the control circuit controls the screen assembly 11 to display time information based on the signal from the clock chip.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
