A seamless display, comprises: a backlight module, that includes a plurality of light emitting sources; an optical film; a partitioned structure; a plurality of LCD panel main bodies; a protection layer having a micro-structure; and a locking portion. The main bodies of a plurality of liquid crystal panels are put together through aligning or overlapping their respective side edges, and then are covered over the partitioned structure. ## Claims ### Claim 1 A method of manufacturing seamless display, including: fixing a light emitting source in a backlight module; fixing an optical film on said light emitting source; placing a partitioned structure on said optical film; aligning or overlapping side edges of main bodies of adjacent liquid crystal panels, and putting the main bodies of the adjacent liquid crystal panels over said partitioned structure; and providing a protection layer having micro-structures over said main bodies of said liquid crystal panels having the side edges aligned or overlapped, thus forming a display unit. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein said protection layer is made of acrylic or glass material, and on its surface is disposed a prism micro-structure made by means of film plating, glue film applying or molding. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein said light emitting source is a flat light source or a quasi-flat light source. ### Claim 4 (depends on 3) The method as claimed, in claim 3, wherein said flat light source is a light-emitting-diode or a flat light tube; and said quasi-flat light source is a curve-shaped light tube. ### Claim 5 (depends on 3) The method as claimed in claim 3, further comprising enabling said flat light source or said quasi-flat light source to emit light at specific angle. ### Claim 6 (depends on 5) The method as claimed in claim 5, wherein said flat light source or said quasi-flat light source is packaged and added light cover, arranged interleavingly into a matrix of equal spacing elements, further including a prism film, a diffuser film or a diffuser plate, disposing a trapezoidal plate on a side of said flat light source or said quasi-flat light source, thus forming a grid-shaped partition structure. ### Claim 7 (depends on 5) The method as claimed in claim 5, further comprising evenly distributing said flat light source. ### Claim 8 (depends on 7) The method as claimed in claim 7, further comprising controlling the optical output of a matrix through a current, making unitary light-emitting-diodes in the perimeter of said matrix to face toward the perimeter of said panel, or changing relative positions of said unitary LED's in respective rows of said matrix. ### Claim 9 (depends on 5) The method as claimed in claim 5, further comprising evenly distributing said quasi-flat light source. ### Claim 10 (depends on 9) The method as claimed in claim 9, wherein at least a ring of light-emitting-diodes are placed in the perimeter of a trapezoidal plate on a side of said quasi-flat light source, or at least a CCFL or a HCFL is placed on each of the respective sides of a trapezoidal plate on a side of said quasi-flat light source. ### Claim 11 (depends on 9) The method as claimed in claim 9, further comprising controlling the optical output of a matrix through a current, making unitary light-emitting-diodes in the perimeter of said matrix to face toward the perimeter of said panel, or changing relative positions of said unitary LED's in respective rows of said matrix. ### Claim 12 A seamless display, comprising: a backlight module, that includes a plurality of light emitting sources; an optical film; a partitioned structure; a plurality of LCD panel main bodies; a protection layer having micro-structure; a locking portion; and a packaged and added light cover of said light emitting sources, said light emitting sources being arranged interleavingly into a matrix of equal spacing elements, further included a prism film, a diffuser film or a diffuser plate, a trapezoidal plate disposed on a side of said light emitting sources, thus forming a grid-shaped partition structure, wherein, main bodies of a plurality of liquid crystal panels are put together through aligning or overlapping respective side edges of the main bodies, and then are covered over said partitioned structure. ### Claim 13 (depends on 12) The seamless display as claimed in claim 12, wherein said protection layer is made of acrylic or glass material, and on its surface is disposed a prism micro-structure made by means of film plating, glue film applying or molding. ### Claim 14 (depends on 12) The seamless display as claimed in claim 12, wherein said plurality of light emitting sources is flat light source. ### Claim 15 (depends on 14) The seamless display as claimed in claim 14, wherein said flat light source is a light-emitting-diode or a flat light tube. ### Claim 16 (depends on 12) The seamless display as claimed in claim 12, wherein said plurality of light emitting sources is a quasi-flat light source. ### Claim 17 (depends on 16) The seamless display as claimed in claim 16, wherein at least a ring of light-emitting-diodes are placed in the perimeter of said trapezoidal plate on a side of said quasi-flat light source, or at least a CCFL or a HCFL is placed on each of the respective sides of said trapezoidal plate on a side of said quasi-flat light source. ### Claim 18 (depends on 16) The seamless display as claimed in claim 16, wherein said quasi-flat light source is a curved-shaped light tube.
