    "3. A display module assembly kit, comprising: an LED panel in which a first coupling member is provided; a cabinet in which a second coupling member is provided and the LED panel is detachably mounted by using the first coupling member and the second coupling member; and an auxiliary tool comprising a body and a plurality of magnets, and configured to magnetize at least one of the first coupling member and the second coupling member when the auxiliary tool is placed on a front surface of the LED panel so that at least one of the first coupling member and the second coupling member is moved by a mutual magnetic force, thereby locking or unlocking the first coupling member with the second coupling member, the auxiliary tool being formed with a size and a shape corresponding to those of the LED panel, wherein the plurality of magnets penetrate the body so that same poles of the plurality of magnets face a same direction.",
    "4. The kit according to claim 3, wherein: one of the first coupling member and the second coupling member comprises a magnetic material; the other of the first coupling member and the second coupling member comprises a magnet; and the auxiliary tool magnetizes the magnetic material so that an attractive force or a repulsive force acts with the magnet and moves at least one of the first coupling member and the second coupling member to a locking or unlocking position.",
    "5. The kit according to claim 3, wherein: the first coupling member is disposed on a back surface of the LED panel and comprises an engaging portion; and the second coupling member is disposed on a front surface of the cabinet and comprises: an accommodating groove configured to accommodate the first coupling member; and a locking portion configured to move to a locking position when the first coupling member is accommodated in the accommodating groove, thereby fixing the engaging portion of the first coupling member.",
    "6. The kit according to claim 3, wherein the auxiliary tool comprises a body provided to have a size and a shape corresponding to the LED panel and a magnet provided to correspond to a position of the first coupling member provided in the LED panel.",
    "7. A display module assembly kit, comprising: an LED panel in which a first coupling member is provided; a cabinet in which a second coupling member is provided and the LED panel is detachably mounted by using the first coupling member and the second coupling member; and an auxiliary tool configured to magnetize at least one of the first coupling member and the second coupling member so that at least one of the first coupling member and the second coupling member is moved by a mutual magnetic force, thereby locking or unlocking the first coupling member with the second coupling member, wherein: the first coupling member is disposed on a back surface of the LED panel and comprises an engaging portion; and the second coupling member is disposed on a front surface of the cabinet and comprises: an accommodating groove configured to accommodate the first coupling member; and a locking portion configured to move to a locking position when the first coupling member is accommodated in the accommodating groove, thereby fixing the engaging portion of the first coupling member, and wherein: the first coupling member comprises a magnetic material; the locking portion of the second coupling member comprises a magnet; and the auxiliary tool magnetizes the magnetic material so that an attractive force acts with the magnet when the first coupling member is accommodated in the accommodating groove and moves the locking portion to the locking position.",
    "8. The kit according to claim 7, wherein the auxiliary tool magnetizes the magnetic material so that a repulsive force acts with the magnet in order to prevent the locking portion from being moved to the locking position before the first coupling member is accommodated in the accommodating groove or in order to move the locking portion from the locking position to an unlocking position.",
    "9. The kit according to claim 7, wherein: the second coupling member comprises a magnetic material configured to maintain the locking portion to be at an unlocking position by the attractive force with the magnet included in the locking portion when the LED panel is not mounted on the cabinet; and the auxiliary tool magnetizes the magnetic material included in the first coupling member so that the attractive force acts with the magnet included in the locking portion in order to move the locking portion to the locking position after the engaging portion of the first coupling member is accommodated in the accommodating groove.",
