     DETAILED DESCRIPTION 
     It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. 
     The description is not to be considered as limiting the scope of the embodiments described herein. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.” 
     The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like. 
       FIG. 1  illustrates a block diagram of an embodiment of a display device. The display device includes a first enclosure  10 , an LCD panel  11 , a drive board  12 , a power board  13 , a video scaler  14 , a wireless high-definition (WiHD) receiver  15 , a second enclosure  20 , a multi-media board  21 , and a WiHD transmitter  22 . The display device can receive video data from a video source  30  and present video images corresponding to the video data. The video source  30  can be a television, a computer, a digital video disc (DVD) player, a gaming device, a smart phone, or any other electronic device. 
     The multi-media board  21  can provide an input/output (I/O) interface for communicating with the video source  30  and receive video data from the video source  30  via the I/O interface. The I/O interface can be a video graphics array (VGA) interface, a high-definition multi-media interface (HDMI), an S-Video interface, a digital video interface (DVI), or any other suitable video interface. 
     The WiHD transmitter  22  and the WiHD receiver  15  can establish a wireless communication channel. The multi-media board  21  can transmit the video data to the video scaler  14  via the wireless communication channel. WiHD is a unified standard which defines a specification for a digital network interface for wireless transmission of high-definition content for consumer electronics products. 
     The video scaler  14  can scale the video data and generate scaled video data of a dimension compatible with the LCD panel  11 . The video scaler  14  can scale the video data in either a horizontal or a vertical direction. The video scaler  14  is connected to the drive board  12  and can transmit the scaled video data to the drive board  12 . 
     The drive board  12  can generate drive signals based on the scaled video data. The drive board  12  is connected to the LCD panel  11  and can transmit the drive signals to the LCD panel  11 . 
     The power board  13  can provide power to the LCD panel  11 . The LCD panel  11  can present video images according to the drive signals received from the drive board  12 . 
     The LCD panel  11 , the drive board  12 , the power board  13 , the video scaler  14 , and the WiHD receiver  15  are housed in the first enclosure  10 . The multi-media board  21  and the WiHD transmitter  22  are housed in the second enclosure  20 . The first enclosure  10  and the second enclosure  20  are separately spaced from each other. 
     The drive board  12  and the LCD panel  11  communicate with each other via a high-speed signal transmission interface. 
     When the resolution of the LCD panel  11  is lower than the Full HD resolution (1920*1080 pixels), the drive board  12  can transmit the drive signals to the LCD panel via a low voltage differential signaling (LVDS) interface. The LVDS interface can operate at low power and can run at very high speeds using inexpensive twisted-pair copper cables. 
     When the resolution of the LCD panel  11  is equal to or higher than the Full HD resolution, the drive board  12  can transmit the drive signals to the LCD panel  11  via a V-by-One HS interface. The V-by-One HS interface can run at faster speeds than the LVDS interface. 
       FIG. 2  illustrates a block diagram of another embodiment of a display device. In the illustrated embodiment of, the display device further includes a third enclosure  40 . The LCD panel  11 , the drive board  12 , the video scaler  14 , and the WiHD receiver  15  are housed in the first enclosure  10 . The multi-media board  21  and the WiHD transmitter  22  are housed in the second enclosure  20 . The power board  13  is housed in the third enclosure  40 . The first enclosure  10 , the second enclosure  20 , and the third enclosure  40  are separately spaced from each other. 
     The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
