Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.

Because of the low power consumption, small volume and low radiation of the liquid crystal display, in addition to the wide popularization in the field of household appliances, the liquid crystal display device is gradually put into practical application in the business field and the education field, for example, the liquid crystal writing board which has the same effect as a blackboard is most conveniently used, and the real-time handwriting and erasing can be realized, but in the existing liquid crystal writing board, the structure is simpler and the writing board consists of the writing board, a liquid crystal material, an embedded circuit, a back board and a battery, when people write on the writing board, the battery supplies power to the embedded circuit through a button, so that the liquid crystal material is in an electric field, and the purpose of erasing handwriting is achieved, but the mode can not realize local erasing, and the writing traces of the whole liquid crystal display screen disappear after each power-on, and the use is inconvenient; the other liquid crystal writing board capable of realizing local erasing is characterized in that an ITO conductive layer is used as a circuit, then infrared induction is utilized to detect a position needing to be erased, and local electrification is carried out to realize local erasing, but the method seriously influences the production efficiency and the production difficulty, so that the cost is high.

Accordingly, referring to fig. 1, the present invention provides a display device 100, wherein the display device 100 includes a display panel 10 and at least one planar conducting wire 20; the display panel 10 has a first surface for facing a user and a second surface; the planar conducting wire 20 is disposed on the second surface, and the planar conducting wire 20 is a closed loop and is used for generating an electric field under the action of a magnetic material to eliminate at least part of the writing on the display panel 10.

In some embodiments, the planar wire is looped to form the closed loop.

In some embodiments, the display device further includes an upper casing 30 disposed on the first surface side and a lower casing 40 disposed on a side of the planar conducting wire away from the display panel 10, where the upper casing 30 and the lower casing 40 sandwich the display panel 10 and the planar conducting wire 20, so as to protect the display device and prolong a service life of the display device.

In other words, the display device 100 includes an upper case 30, a display panel 10, a planar wire 20, and a lower case 40 in sequence from top to bottom.

In some embodiments, when the area of the display device 100 is small, the planar conducting wire 20 can be bonded to the second surface by, but not limited to, glue bonding, which improves the processing efficiency while ensuring that the functional use of the display device is not affected; when the display device 100 has a large area, in order to reinforce the stability of the bonding between the planar wires 20 and the second surface, screws may be selected to reinforce the planar wires and the lower case 40.

In some embodiments, the display panel 10 and the planar conducting wires 20 are sandwiched between the upper casing 30 and the lower casing 40, and the sides of the lower casing 40 are fixed on the sides of the upper casing 30 by means of tenon fixing, adhesive bonding or screws, so as to form a sandwich structure, thereby obtaining the display device of the present invention. The upper case 30 and the lower case 40 are mainly used to protect the display panel and prolong the service life of the display device, and the upper case 30 is made of a transparent material.

In this embodiment, the display panel 10 is a liquid crystal film, and the liquid crystal film includes a first conductive layer 11, a second conductive layer 12, and a liquid crystal material 13 filled between the first conductive layer and the second conductive layer.

In the present invention, the planar conducting wire 20 is a closed loop, but is not connected to a power source, i.e. the display device has no power source to supply power to the display device. When the magnetic material moves in the first surface or the space close to the first surface, the plane conducting wire and the magnetic material form relative motion to generate an electromagnetic induction phenomenon, so that an electric field is generated around the plane conducting wire, and the arrangement mode of liquid crystal molecules in the liquid crystal material can be changed by the electric field, so that traces on the display device are removed; in other words, as shown in fig. 2, the magnetic material is a magnet, when the magnet moves in the first surface or a space close to the first surface, the magnet performs a magnetic induction line cutting motion relative to the planar conducting wire, and because the planar conducting wire is a closed loop, an electric field is generated around the planar conducting wire according to an electromagnetic induction phenomenon, and liquid crystal molecules are orderly arranged under the action of the electric field, that is, the purpose of removing traces on the liquid crystal display device is achieved.

In some embodiments, the planar wires include at least one, and the planar wires are distributed on the second surface in a matrix form. According to the actual requirement on the resolution of the display device, the resolution can be adjusted by changing the number of the planar wires in a unit area, and when the requirement on the resolution of the display device is higher, the number of the planar wires in the unit area can be increased; and the planar conducting wires can realize the function of accurately erasing the local part of the liquid crystal display device through matrix distribution.

In this embodiment, the display device further includes a magnetic material 50 for generating an electric field to the planar conducting wire, and the magnetic material 50 is used for moving in the first surface or a space adjacent to the first surface. The shape of the magnetic material 50 includes, but is not limited to, a rectangular parallelepiped shape, a bar shape, and the like. The magnet has the main function of moving relative to the planar conducting wire, so that the planar conducting wire cuts the magnetic induction wire to generate an electric field, the arrangement mode of liquid crystal molecules is adjusted, and the erasing function is realized.

In one embodiment, the display device comprises two magnetic materials, one of which is free to move; the other magnetic material is in a strip shape (not shown) and is connected to the display panel in a sliding manner, the length of the strip-shaped magnet is equal to the width of the display device, when the liquid crystal display device is completely erased, the strip-shaped magnetic material is dragged, the purpose of completing erasing at one time is achieved, and the physical force and time for slowly erasing by using a small magnet are saved; when only partial erasing is needed, the magnetic material capable of freely moving is used for partial erasing, so that the flexible and convenient effect is achieved.

In some embodiments, the planar wire is formed by a closed wire which is encircled from the center to the outside in a circular encircling manner or a rectangular encircling manner. Preferably, as shown in fig. 3, the planar wires are surrounded in a rectangular manner, which can avoid the problem that the wires have large area of vacant sites when distributed in a matrix, which leads to difficult local erasing during erasing. In this embodiment, the rectangular winding coils distributed in a matrix of 6 × 14 are used, so that dead corners can be prevented from being erased.

In some embodiments, the planar wires are formed by closed wire pitch bending, as shown in fig. 4.

In some embodiments, the diameter of the planar wire is greater than 6mm, so that the coil can generate an induction electric field greater than 2V when cutting the magnetic induction wire, thereby facilitating the rapid and ordered arrangement of liquid crystal molecules and improving the erasing efficiency.

A method for realizing a display device specifically comprises the following steps:

s01: providing a display device as described above;

s02: applying pressure on the display panel by using a hard object and painting to realize the display function of the display device;

s03: then moving the magnetic material in the space at or near the first surface;

s04: and realizing the erasing function of the display device.

Specifically, the specific implementation method of the display device for performing the erasing function is as follows:

when the magnetic material moves in the first surface or a space close to the first surface, the magnetic material and the planar wire move relatively to generate an electromagnetic induction phenomenon, an induction electric field is generated around the planar wire, and the direction of the induction electric field is perpendicular to the planar wire, so that the liquid crystal molecules rotate under the action of the electric field and are orderly arranged, and the erasing function of the display device is realized. When the magnetic material does not move, the induced electric field disappears, and the liquid crystal molecules return to the disordered arrangement state.

The display device is applied to a liquid crystal writing board, and the size of the liquid crystal writing board can be produced according to practical application scenes, such as a liquid crystal writing board with the size of A4 which is convenient to carry, a blackboard for teaching and the like.
