    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

    [0035] The term embodiment used in this description refers to an example, a demonstration, or an illustration. In addition, the two indefinite articles a and an used in this description and claims are generally understood as one or more/a plurality of unless a specific single form is pointed out or is determined in the context.

    [0036] A display panel of the present disclosure includes an array panel and a plurality of display devices. The display devices are transferred to the array panel by a device transferring equipment.

    [0037] One of the display devices of the present disclosure includes a display device main body 101 and a magnetic member 102. The display device main body 101, for example, can be a micro light-emitting diode (LED).

    [0038] The magnetic member 102 is disposed on the display device main body 101.

    [0039] The display device assembled by the display device main body 101 and the magnetic member 102 can be transferred to the array panel under a force of a magnetic field outside of the display device, so that the display devices and the array panel compose the display panel.

    [0040] One of the display devices transferred to the array panel becomes a display unit of the display panel.

    [0041] The magnetic member 102 is disposed in at least one end of the display device main body 101.

    [0042] The magnetic member 102 is a magnetic conductive material layer, which is formed by disposing a magnetic conductive material in the at least one end of the display device main body 101.

    [0043] The magnetic member 102 is used to allow a predetermined portion of the display device to contact the array panel when the display device is transferred to the array panel.

    [0044] The magnetic conductive material can be a metal, such as iron (Fe), nickel (Ni), and cobalt (Co), or it can be a FeNiCo oxide, a FeNiCo chemical compound, or a FeNiCo alloy.

    [0045] The magnetic member 102 made by the magnetic conductive material is used to accept a magnetic pull force or a magnetic push force of a magnetic field.

    [0046] The display device main body 101 includes a first electrode 1011 and a second electrode 1012.

    [0047] The first electrode 1011 and the second electrode 1012 are disposed on two opposite-direction surfaces of the display device main body 101, respectively. That is, the first electrode 1011 and the second electrode 1012 are respectively disposed on a first surface and a second surface of the display device main body 101. The first surface and the second surface are surfaces of the display device main body 101 along a first direction 103 and a second direction 104, respectively. The first direction 103 and the second direction 104 are opposite. As shown in FIG. 1, the magnetic member 102 is disposed (attached) on the first electrode 1011 or the second electrode 1012 of the display device main body 101.

    [0048] In another way, the first electrode 1011 and the second electrode 1012 are disposed on two same-direction surfaces of the display device main body 101, respectively. That is, the first electrode 1011 and the second electrode 1012 are respectively disposed on a third surface and a fourth surface of the display device main body 101. The third surface and the fourth surface are surfaces of the display device main body 101 along a third direction (parallel with the first direction 103 or the second direction 104). The third surface and the fourth surface are in the same plane, or the third surface and the fourth surface are respectively two stepped surfaces, which are disposed in a step shape, of the display device main body 101 along the third direction. The magnetic member 102 is disposed (attached) on the first electrode 1011 or the second electrode 1012 of the display device main body 101.

    [0049] In the situation that the third surface and the fourth surface are in the same plane, or the third surface and the fourth surface are respectively two stepped surfaces, which are disposed in a step shape, of the display device main body 101 along the third direction, the first electrode 1011 and the second electrode 1012 are respectively disposed on the third surface and the fourth surface and have a predetermined distance in a direction perpendicular to the third direction. As shown in FIG. 2, specifically, in the situation that the third surface and the fourth surface are in the same plane, there is a groove between the third surface and the fourth surface.

    [0050] In the situation that the third surface and the fourth surface are respectively two stepped surfaces, which are disposed in a step shape, of the display device main body 101 along the third direction, there is a step spacing between the third surface and the fourth surface in the third direction or in the direction perpendicular to the third direction (as shown in FIG. 3).

    [0051] The magnetic member 102 is used to give a force to the display device main body 101 under a magnetic field. The magnetic member 102 is used to give a force to at least one side of the display device main body 101 under the magnetic field, so as to allow a predetermined portion of the display device to contact the array panel.

    [0052] In the present disclosure, an electrode/electrode assistant layer of a micro LED is made of a magnetic conductive material.

    [0053] No matter whether a horizontal structure or a vertical structure, after a semiconductor process, anode electrodes and cathode electrodes are disposed by a sputtering or depositing process. For example, in a horizontal structure, after a common LED is disposed anode and cathode electrodes, one end of the LED is disposed one layer of the magnetic conductive material, such as a metal of iron (Fe), nickel (Ni), cobalt (Co), or a FeNiCo oxide, a FeNiCo chemical compound, or a FeNiCo alloy. The purpose of the magnetic conductive material layer is used to allow the end of the LED to be attracted by a magnet.

    [0054] In a micro LED of a horizontal structure, which is different from a micro LED of a vertical structure, after the anode and cathode electrodes are finished, it is necessary to dispose one layer of the magnetic conductive material.

    [0055] By adding a magnetic conductive layer outside of the electrode, using magnetic force to control the micro LED is possible.

    [0056] By the above-mentioned technical solution, because a display device of the present disclosure further includes a magnetic member 102, and the magnetic member 102 is disposed on a display device main body 101, the display device assembled by the display device main body 101 and the magnetic member 102 can be transferred to an array panel under a force of a magnetic field outside of the display device. Therefore, the present disclosure can efficiently transfer the display devices to the array panel of a display panel.

    [0057] The present disclosure has been described with preferred embodiments thereof and it is understood that many changes and modifications to the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
