     Please refer to  FIG. 1  to  FIG. 3  together, the support  10  provided by the present application is illustrated now. The support  10  is configured to be disposed between the corners of the packing case and corresponding corners of the LCD screen, which plays a buffer and insulation effect on four corners of the LCD screen when the soft cushion is mounted on the support  10 , thus preventing the corners of the LCD screen from impacting the packing case. The support  10  includes two partition plates  11 , the two partition plates  11  are arranged perpendicular to each other, and the two partition plates  11  are fixedly connected; when the support  10  is disposed at the corner of the packing case, the two partition plates  11  respectively extend to corresponding two side edges of corresponding corner of the LCD screen during use. The surface of each of the partition plates  11  close to another partition plate  11  is defined as an inner surface  111 , each of the inner surfaces  111  is provided with a locating feature  112  configured to locate and bond the soft cushion  20 . The locating feature  112  is provided to facilitate bonding the soft cushion  20  on the partition plate  11 , so as to prevent the soft cushion  20  from being attached crookedly. 
     The support  10  provided by the present application, compared with the prior art, the inner surfaces  111  of the two partition plates  11  of the support  10 , in the present application, are provided with a locating feature  112  configured to locate the soft cushion  20 , thereby the soft cushion  20  may be located through the locating feature  112  when the soft cushion  20  is bonded to the inner surface  111  of the partition plate  11 , such that the soft cushion  20  is fitted to the support  10  quickly and explicitly, and better matches with the LCD screen, hence reducing errors.
