Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a liquid crystal display (LCD) for mobile phones and a backlight unit, and more particularly, LCD liquid crystal screen and backlight bonding device that aligns backlight and LCD automatically by supplying liquid crystal screen, and pressboard is lowered from the upper side to connect mobile phone LCD and backlight to eliminate defective bonding and ensure accurate bonding .
As is well known, an information display device is an electronic device used as an electro-optical device for converting an electrical signal into a visual image and allowing the human to directly read information.
As one of such electronic information display devices, there are CRT (Cathod-Ray Tube), LED (Light Emitting Diode), PDP (Plasma Display Panel) and LCD which have recently been spotlighted, There is no blur and no static electricity. Therefore, researches for applying LCD to notebooks, CAR navigation systems, computer monitors, and mobile phones have become more active recently.
In general, a liquid crystal display device is equipped with a BLU for diffusing and illuminating light. Such a BLU is a direct-type method of directly illuminating the front surface of a panel by placing a light source under the LCD panel, A light source is placed on the side,
And an edge method in which the light is illuminated by a reflector or the like.
In particular, LCDs used in mobile phones employ edge-based BLUs, and these BLUs are composed of a combination of a backlight assembly and optical films.
A BLU having a thin rim is supplied to a standard or guide having a predetermined size, and then an LCD is supplied to the upper side of the BLU so that the BLU and the LCD are combined to be integrated.
However, when BLU is supplied, it is not limited to a specific part but a bending phenomenon occurs at various positions on a frame made of thin injection molding. When the LCD is placed on the upper side of the bent BLU, The BLU protrudes outside the LCD without being uniformly bonded on the entire surface of the LCD. This causes a defect, and the defective portion reaches 10% when the work is combined with the work, And it is very difficult to apply to a jig.
In addition, it is difficult to apply a variety of jigs due to various sizes and shapes of BLUs and LCDs, and even when applied to a jig, there is still a drawback that the productivity is lowered due to a large number of defects in a bonding operation using manpower.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a liquid crystal display (LCD) that is capable of simultaneously operating an upper, lower alignment, The upper and lower alignment pads and both side alignment pads are driven at the same time to align the BLU and the LCD together so as to prevent the BLU from being deformed at any portion to enable accurate bonding.
Another object of the present invention is to arrange the BLU and the LCD together and drive the pushing and fixing device from the upper side to automatically and uniformly bond the BLU and the LCD on all sides by pressing the LCD.
The present invention relates to a liquid crystal display device, A bonding apparatus for supplying a BLU and an LCD to an upper side of an upper plate provided with an operation switch in order to align the upper and lower alignment bars with the side alignment,
The upper and lower movable bands connected to the upper and lower alignment bands and connected to the upper and lower driving bands provided at both sides of the upper and lower drive shafts connected to the upper and lower driving motors are simultaneously driven to align the upper and lower sides of the BLU and LCD. Wow;
A timing pulley connected to the side alignment belt, a timing pulley provided in the side drive motor, and a side pulley connected to the side drive belt disposed on both sides of the timing pulley connected to the timing belt at one end, A side aligning device for aligning both side surfaces of the side surface aligning device;
A cylinder connected to a lower side of the alignment space between the upper and lower alignment units and adapted to adjust a height of the alignment space above the cylinder support;
And a pushing and fixing device in which a pressure plate is installed below the upper and lower conveying belts to which the cylinder axis of the air cylinder provided at the cylinder fixing stand protruded from the rear side of the upper plate to the upper side of the side plate is provided.

In the present invention, when the BLU is supplied, the upper and lower alignment pads and both side alignment pads are driven simultaneously to set a position for work with a narrower gap in the opposite direction, and the upper and lower alignment pads and both side alignment pads So that it is possible to arrange the supplied BLUs accurately at the same time.
In the present invention, when an LCD is supplied to the upper side of the BLU, the upper and lower alignment pads and the both side alignment pads are simultaneously driven in a standby state after aligning the BLUs so that the BLU and the LCD are aligned together. So as to prevent the deformation phenomenon and provide an effect of being aligned together to enable accurate bonding.
The present invention provides an effect of automatically aligning the BLU and the LCD uniformly on all sides by aligning the BLU and the LCD and then pushing the push plate downward from the upper side to push the LCD supplied on the upper side.
