detailed description

The technical solutions of the embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. As shown in FIG. 1-2, this embodiment is to provide a portable display screen, which includes a housing portion 1, a display portion 2, a circuit board portion 3 arranged in this order from left to right, and a housing portion 1 and a display portion 2 The first folding portion 4 is foldably connected, and the display screen portion 2 and the circuit board portion 3 are foldably connected through the second folding portion 5.

It should be noted that the housing portion 1 and the display screen portion 2 are foldably connected by the first folding portion 4 means that the housing portion 1 and the display screen portion 2 are connected by the first folding portion 4, and the housing portion 1 and the display screen portion 2 can be folded with each other; the display portion 2 and the circuit board portion 3 are foldably connected by the second folding portion 5 means that the display portion 2 and the circuit board portion 3 are connected by the second folding portion 5, and the display portion 2 and the The circuit board portion 3 can be folded with each other.

In some embodiments, the outer shell portion 1 is composed of a first soft material layer at the bottom, a first reinforcing plate (the reinforcing plate 6 shown in FIG. 4 includes the first reinforcing plate), and the first reinforcing plate is wrapped in The second soft material layer on the bottom of the first soft material layer is composed.

In some embodiments, as shown in FIGS. 3-5, the display screen portion 2 includes a fixed layer at the bottom and a display panel layer fixed on the upper surface of the fixed layer, the fixed layer includes a third soft material layer at the bottom, A second reinforcing plate (the reinforcing plate 6 shown in FIG. 4 includes the second reinforcing plate) and a fourth soft material layer covering the third soft material layer at the bottom with the second reinforcing plate. The display panel layer includes a display panel 21 and a rectangular frame 22 surrounding the outer edge of the display panel 21. The package frame 22 is made of soft material, such as leather, fiber or silicone. The package frame 22 and the display panel 21 are fixed by pasting. The whole of the package frame 22 and the display panel 21 and the fixing layer are also fixedly connected by pasting. The package frame 22 made of the soft material directly covers the display panel 21 to form an integrated structure, so that the display panel 21 no longer needs to be provided with a protective cover such as a rigid outer frame and a soft shell, which reduces the overall thickness of the portable display screen .

In some embodiments, the outer edge size of the bezel 22 is smaller than the outer edge size of the fixing layer. This arrangement can ensure that when the portable display is dropped accidentally, the third soft material layer of the fixed layer can play a certain buffering role, thereby reducing the impact force received by the display panel 21.

In some embodiments, the circuit board portion 3 includes a bottom support layer, a circuit board layer fixed on the upper surface of the support layer; the support layer is composed of a fifth soft material layer at the bottom and a fifth soft material layer Composed of a layer of sixth soft material. The circuit board layer includes a rectangular circuit board support 31, two third reinforcing plates provided inside the circuit board support 31 (the reinforcing plate 6 shown in FIGS. 4-5 includes the third reinforcing plate), The circuit board body 32 between the third reinforcing plates and the seventh soft material layer covering the entire outer surface of the circuit board support 31. The circuit board bracket 31 is fixed on the upper surface of the support layer. After the circuit board body 32 and the third reinforcement board are installed on the circuit board bracket 31, the seventh soft material layer is entirely wrapped on the outer surface of the circuit board bracket 31 , The installation of the circuit board section 3 is completed.

In some embodiments, the side wall of the circuit board holder 31 is provided with a number of different ports 33, which can be used to connect a mini high-definition cable for data transmission, or an external power supply to charge and discharge the circuit board body. The structure of the circuit board part can also be provided with a touch sensor or a key separately, which is used to trigger the voice input instruction of the screen.

In some embodiments, the first folding portion 4 and the second folding portion 5 have the same structure and are made of soft materials. In this embodiment, the first folding portion 4 and the second folding portion 5 use the eighth soft material layer Cover the structure on the ninth soft material layer.

Therefore, a corresponding rectangular notch 8 is provided on the second reinforcing plate of the fixed layer of the display unit 2 and the fourth soft material layer on the upper part thereof. The rectangular notch 8 is used to place the connector of the FPC cable; The seventh flexible material layer on the upper part of the support layer and the third reinforcing plate on the lower layer in the circuit board holder 31 are also provided with corresponding rectangular notches 8 for placing the connection seat of the FPC cable. The upper surface of the bottom soft material layer of the circuit board portion 3, the second folding portion 5 and the display screen portion 2 is provided with a groove that communicates with each other, and is used for threading the cable. After the connection of the cable structure at the groove and the rectangular notch 8 is completed, an electrical connection is formed between the display panel 21 and the circuit board body 32 to facilitate signal transmission. For the sake of beauty, the cable of the second folding portion 5 is covered between the two layers of the seventh soft material layer, so as to be hidden.

In this embodiment, the soft material of the soft material layer may be a leather material, or other soft materials such as silica gel, cloth, etc .; the soft material layer is covered with another soft material layer, and the cloth may be covered with leather. In this embodiment, the reinforcing plate 6 is made of hard materials, such as plastic plates, wooden boards, and other plates with a certain hardness.

In this embodiment, the housing portion 1, the display portion 2 and the circuit board portion 3 may adopt an integrated structure, that is, the fixing layer of the housing portion 1, the display portion 2 and the support layer of the circuit board portion 3 use the same soft material layer As the bottom layer, after the installation of the reinforcing plate 6 at the corresponding part is completed, another layer of soft material is used to cover the entire bottom layer material. At this time, the first folding portion 4 and the adjacent outer shell portion 1 and display screen portion 2. The second folding portion 5 forms an integrated structure with the adjacent display screen portion 2 and circuit board portion 3. However, the first folding portion 4 and the second folding portion 5 may also adopt other structures than the integrated structure mentioned in this embodiment, as long as the corresponding components can be folded.
