     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Specific implementations of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementations described here are only used for illustrating and explaining the present invention rather than limiting the present invention. 
     As one aspect of the present invention, a remote controller is provided, as shown in  FIGS. 2 to 5 , the remote controller includes a control module and a transmitter module electrically connected to each other, the remote controller is provided with at least five direction keys  10 , each of which corresponds to a different control direction, and when any one of the direction keys  10  is pressed, the control module can control the transmitter module to transmit a direction remote control signal corresponding to the pressed direction key  10  to a remotely controlled display device. 
     A traditional remote controller is provided with only four direction keys, which respectively correspond to four control directions, namely, up, down, left and right directions (as shown in  FIG. 1 ). However, the remote controller provided by the present invention is provided with at least five direction keys  10  to correspond to at least five control directions, so that the user can more conveniently operate a corresponding object (for example, mouse cursor, menu, etc.) on the remotely controlled display device to move. 
     Preferably, as shown in  FIG. 2 , the remote controller may be provided with eight direction keys  10 , that is, the eight direction keys  10  may be arranged on the remote controller to correspond to eight different control directions, so that the user can operate the corresponding object on the remotely controlled display device to move in eight different directions. Compared with the prior art, the convenience of the operation is obviously improved. 
     More preferably, as shown in.  FIG. 2 , the control directions corresponding to the eight direction keys  10  are upper left, up, upper right, right, lower right, down, lower left, and left, respectively. By employing the aforementioned structure, the user can operate the corresponding object on the remotely controlled display device to move in eight directions, namely, upper left, up, upper right, right, lower right, down, lower left, and left directions. Compared with the prior art, movable direction is partitioned more finely, thereby simplifying the operation steps needed to move or position the corresponding object through the remote controller. 
     Preferably, as shown in  FIG. 2 , the eight direction keys  10  may be arranged to form a ring. Specifically, the eight direction keys  10  may be arranged to form a ring on the remote controller according to the respective corresponding control directions. For example, the direction key  10  with upper left control direction may be arranged in an upper left position of the ring, which facilitates intuitive operation of the user, and meanwhile facilitates switching among the keys. 
     Preferably, for each direction key  10 , a corresponding circuit module may be arranged therebelow (in an inward direction perpendicular to the principal plane), and when any one of the direction keys  10  is pressed, the circuit module corresponding to the pressed direction key  10  can be connected to the control module. Specifically, below each direction key  10 , a circuit module corresponding thereto may be arranged. For example, a circuit module corresponding to an upper left control direction may be arranged below the direction key  10  with the upper left control direction, and the circuit modules may be differentiated by different preset voltage values or current values. Therefore, when any one of the direction keys  10  is pressed, the circuit module arranged below said direction key is connected to the control module, so that the control module can acquire the control direction corresponding to the pressed direction key  10  according to the current voltage value or current value and the preset different voltage values or current values, for example, thereby controlling the transmitter module to transmit a corresponding direction remote control signal. 
     More preferably, as shown in  FIG. 3 , the direction key may include a press portion  11  and a conductive portion  12  located at a lower end of the press portion, the circuit module may be provided thereon with a switch circuit structure  20  in an off state, and when the press portion  11  of any one of the direction keys  10  is pressed, the conductive portion  12  of the direction key  10  can switch on the switch circuit structure  20  of the circuit module corresponding to the direction key  10 , so as to connect the circuit module to the control module. Specifically, as shown in  FIG. 3 , an elastic support  30  for supporting the direction key  10  may be arranged below the direction key  10 , so that the direction key  10  is in an up state when not being pressed. With the aforementioned structure, when the direction key  10  is not pressed, the switch circuit structure  20  remains in the off state, when the direction key  10  is pressed, the switch circuit structure  20  can be switched on through the conductive portion  12  so as to connect the circuit module corresponding to the pressed direction to the control module, so that the control module can acquire the control direction corresponding to the pressed direction key  10 . The elastic support  30  may be made of a member capable of providing elasticity, such as spring, elastic sheet, etc., which is not repeatedly described herein. 
     Preferably, the conductive portion  12  may be made of a conductive rubber. By employing the conductive rubber, not only the switch circuit structure  20  can be switched on, but also the down force during pressing the direction key  10  can be buffered, thereby allowing an operator to operate more comfortably. 
     More preferably, the press portions  11  of two or more direction keys  10  may be connected to form an integral structure. Specifically, as shown in  FIGS. 4 and 5 , the press portions  11  of the eight direction keys  10  respectively corresponding to upper left, up, upper right, right, lower right, down, lower left, and left control directions may be connected to form an integral structure, alternatively, the press portions  11  of some direction keys  10  may be connected to form an integral structure as required. The press portions  11  of the eight direction keys  10  are integrally formed to facilitate switching among the direction keys  10  by the user, and at the same time, only one corresponding ring-shaped hole needs to be provided in a panel of the remote controller, which facilitates processing and manufacturing. In addition, since the press portions  11  are of an integral structure, an integral molding process may be employed, which facilitates both processing and assembling. Specifically, as shown in  FIG. 5 , when the press portions  11  of the eight direction keys  10  are integrally formed, the conductive portions  12  of the direction keys  10  may be independent mutually, in order to switch on the switch circuit structure of the corresponding circuit module. 
     The remote controller provided by the present invention is described as above. It can be seen that, in the present invention, by arranging more direction keys each corresponding to a different control direction on the remote controller, when a different direction keys is pressed, the control module can control the transmitter module to transmit a direction remote control signal corresponding to the pressed direction key, so as to enable the corresponding object on the remotely controlled display device to move in more directions, and significantly simplify operation steps required for carrying out moving or positioning operation through the remote controller. Compared with the prior art, it is more suitable for the application requirements of a smart TV platform. 
     As another aspect of the present invention, a display device is provided, the display device includes a signal receiving module and a processing module, which may be electrically connected to each other; the signal receiving module may be used to receive the direction remote control signal transmitted by the remote controller provided by the present invention, and the processing module may be used to control the remotely controlled object on the display device to move toward a corresponding direction according to the direction remote control signal. 
     The display device provided by the present invention, including the signal receiving module and the processing module, receives the direction remote control signal from the remote controller through the signal receiving module, and processes the received direction remote control signal through the processing module, so that the remotely controlled object on the display device is controlled to move toward a corresponding direction, thereby achieving convenient remote control operation of the display device. 
     As still another aspect of the present invention, a remote control display system is provided, the remote control display system includes the remote controller provided by the present invention and the display device provided by the present invention, wherein, the display device provided by the present invention can receive the direction remote control signal transmitted by the remote controller provided by the present invention, and control the corresponding object to move toward the corresponding direction. 
     The remote control display system provided by the present invention, including the remote controller and the display device, may achieve convenient remote control operation experience through interaction between the remote controller and the display device. 
     It may be understood that, the foregoing implementation are exemplary implementations merely used for describing the principle of the present invention, and the present invention is not limited thereto.
