Further, the present invention relates to a flat panel display adhering apparatus in which a backlight unit (BLU Mold) of various sizes and a glass of a liquid crystal panel are aligned and can be precisely adhered.

LCD is a display device that displays images by generating light and shade by injecting a liquid crystal having intermediate properties between solid and liquid between two thin glass plates to change the arrangement of liquid crystal molecules when power is supplied.

(BACK Light Unit) which can not be used without a back light source and can keep the whole screen uniform brightness because it is a non-light emitting type (light receiving element) unlike PDP, FED, BLU).

The backlight unit and LCD are adhered and assembled with urethane adhesive tape tightly. The tape absorbs external impact, prevents leakage of static electricity, electromagnetic waves and foreign matter, and prevents leakage of light source.

On the other hand, after assembly, the flat panel display device may be treated as a defective product due to reasons such as poor assembling between the backlight unit and the LCD or adhesion failure of the adhesive tape.

In this case, a work process for separating the backlight unit adhered with the adhesive tape from the LCD is required, which causes a problem of an increase in cost cost.

A liquid crystal panel adhering apparatus for solving the above problems is shown in FIG. 1 and is disclosed in Korean Patent Registration No. 10-1440190. However, the apparatus is configured such that the liquid crystal panel is adhered to the LCD panel 14 according to the size of the backlight unit 21 and the LCD 14 It is troublesome to replace the unit 16.
