wherein the source printed circuit board is mounted on the first frame and is electrically connected with the liquid crystal panel, the control printed circuit board is electrically connected to the source printed circuit board to drive the liquid crystal panel, and the control printed circuit board being removable from the source printed circuit board and the first frame, and
wherein the first frame has at least one first coupling segment and at least one second coupling segment to hold, respectively, opposing edge surfaces of the control printed circuit board, and the control printed circuit board and the liquid crystal panel are disposed on opposite sides of the first frame.
2. The liquid crystal display module according to claim 1 , wherein at least one notch is formed at a first one of the opposing edge surfaces of the control printed circuit board.
3. The liquid crystal display module according to claim 2 , wherein the control printed circuit board further has at least one notch at a second one of the opposing edge surfaces thereof.
4. The liquid crystal display module according to claim 1 , wherein each of the first and second coupling segments has the shape of a hook.
5. The liquid crystal display module according to claim 1 , wherein each of the first and second coupling segments has the shape of a capsized letter “L”.
6. The liquid crystal display module according to claim 1 , wherein a number of the first coupling segments and a number of the second coupling segments are the same.
7. The liquid crystal display module according to claim 6 , wherein a first distance between two adjacent first coupling segments is smaller than a corresponding side length of the control printed circuit board, and wherein a second distance between the two adjacent second coupling segments is the same as the first distance.
8. The liquid crystal display module according to claim 1 , further comprising a flexible printed circuit to electrically connect the source printed circuit board with the control printed circuit board.
9. The liquid crystal display module according to claim 8 , wherein the flexible printed circuit is removable from the control printed circuit board.
10. The liquid crystal display module according to claim 1 , wherein a tape carrier package electrically connects the source printed circuit board with the liquid crystal panel.
11. The liquid crystal display module according to claim 1 , further comprising a back light unit having a lamp to produce light.
12. The liquid crystal display module according to claim 11 , further comprising a lower cover to support the first frame to prevent wrinkling and bending of the first frame, the lower cover being coupled to the lower frame at a side of the lower frame where the lamp of the back light unit is disposed.
13. The liquid crystal display module according to claim 11 , further comprising a lower cover to support the first frame to prevent wrinkling and bending of the first frame, the lower cover being coupled to the lower frame at a side opposite to the lower frame opposite the lamp of the back light unit.
