Abstract

In a display panel module, a first group and a second group of data driver chips are separately cascaded on a first side of a display panel. A scan driver chip is disposed on a second side of the display panel. A first flexible printed circuit (FPC) is connected between a printed circuit board (PCB) and the display panel for transmitting signals to the first group of data driver chips, the second group of data driver chips and the scan driver chip, respectively.

Claims (17)

1. A display panel module, comprising:

a printed circuit board;

a display panel having a first side and a second side;

a first cascaded group of data driver chips mounted on the first side of the display panel;

a second cascaded group of data driver chips mounted on the first side of the display panel;

at least one scan driver chip mounted on the second side of the display panel;

a first flexible printed circuit board, disposed between the printed circuit board and the display panel, for transmitting signals including a power signal to the first group of data driver chips, the second group of data driver chips and the scan driver chip, respectively, the first flexible printed circuit board cascading the power signal to a first plurality of data driver chips in the first and second groups separately; and

a second flexible printed circuit board, disposed between the printed circuit board and the display panel, for transmitting signals including the power signal to at least one of the first group and the second group, the second flexible printed circuit board cascading the power signal to a second plurality of data driver chips excluding the data driver chips in the first plurality, in the first and second groups separately.

2. The display panel module as claimed in claim 1 , wherein the first flexible printed circuit board is disposed adjacent to the middle of the first side of the display panel.

3. The display panel module as claimed in claim 1 , wherein the number of the first group of data driver chips is the same as the number of the second group of data driver chips.

4. The display panel module as claimed in claim 1 , wherein the number of the first group of data driver chips is different from the number of the second group of data driver chips.

5. The display panel module as claimed in claim 1 , wherein the second flexible printed circuit board is disposed adjacent to one end of the printed circuit board.

6. The display panel module as claimed in claim 1 , wherein the signals comprise data signals and power signals.

7. The display panel module as claimed in claim 1 , wherein the printed circuit board transmits the signals to the scan driver chip through the first flexible printed circuit board and the first group of data driver chips.

8. The display panel module as claimed in claim 1 , wherein the printed circuit board transmits the signals to the scan driver chip through the first flexible printed circuit board.

9. The display panel module as claimed in claim 1 , wherein the display panel includes a signal transmission path for transmitting the signals.

10. The display panel module as claimed in claim 9 , wherein the signal transmission path is parallel to a cascading signal propagation path through at least one of the first group and the second group of data driver chips.
