Abstract

The present invention discloses a large-scale display device, which comprises a first display unit, a second display unit, a black margin area between the first display unit and the second display unit, and two polarizers attached to two surfaces of the first and second display units. The second display unit is arranged in parallel to the first display unit.

Claims

1. A large-scale display device, comprising:

a first display unit comprising a first thin film transistor substrate and a first color filter substrate corresponding thereto;

a second display unit comprising a second thin film transistor substrate next to the first color filter substrate and a second color filter substrate next to the first thin film transistor substrate, the second display unit being arranged parallel to the first display unit;

a black margin area between the first display unit and the second display unit; and

two polarizers attached to two surfaces of the first and second display units.

2. The large-scale display device of claim 1, further comprising a plurality of spacers and liquid crystal between the first thin film transistor substrate and the first color filter substrate in the first display unit.

3. The large-scale display device according to claim 1, further comprising a plurality of spacers and liquid crystal between the second thin film transistor substrate and the second color filter substrate in the second display unit.

4. The large-scale display device according to claim 1, further comprising a control circuits unit connecting to the first display unit and the second display unit.

5. The large-scale display device according to claim 1, wherein the control circuits unit is fastened to the flexible printed circuit board by means of lead.

6. The large-scale display device according to claim 1, further comprising a combination portion in the black margin area to combine the first display unit and the second display unit, and a connection portion to electrically connect the first display unit to the second display unit.

7. The large-scale display device according to claim 6, wherein the combination portion comprises opaque gel.

8. The large-scale display device according to claim 6, wherein said connection portion comprises conduction epoxy.
