Embodiment 1
[0036] like figure 2 As shown, this embodiment provides a display driver chip 1, which can be a gate driver chip (GateDriverIC) for driving gate lines, or a data driver chip (DataDriverIC) for driving data lines, etc. The display driver chip 1.
[0037] The display driver chip 1 has a plurality of output ports, and each output port is used to connect a driving line 71 (gate line, data line, common electrode line, etc., including the part located in the expansion area 91 and the part located in the display area 92). part) and provide a drive signal for it. The number of output ports of each display driver chip 1 is usually tens to hundreds, which can be determined according to its model.
[0038] like figure 2As shown, the display driver chip 1 of this embodiment is arranged on the printed circuit board 82, and the printed circuit board 82 is connected to the array substrate 9 through the flexible circuit board 81, and the output ports of the display driver chip 1 are conn...
Embodiment 2
[0059] Such as image 3 As shown, this embodiment provides a display driver chip 1 assembly, which includes a display driver chip 1 and a flexible circuit board 81. The display driver chip 1 includes a plurality of output ports, and each output port is connected to a connection line on the flexible circuit board 81. 72, and the connecting line 72 is used to connect the driving line 71.
[0060] Preferably, the display driver chip 1 can be directly arranged on the flexible circuit board 81 , that is, the display driver chip 1 component is preferably a chip-on-chip film. At this time, the output port of the display driving chip 1 can be directly connected to the driving line 71 on the array substrate 9 through the connection line 72 on the flexible circuit board 81 .
[0061] Of course, the display driver chip 1 can also be disposed on the printed circuit board 82 , and the printed circuit board 82 is connected to the array substrate 9 through the flexible circuit board 81 .

Embodiment 3
[0069] This embodiment also provides a display device, which includes the above-mentioned display driving chip or display driving chip assembly.
[0070] Preferably, the display device of this embodiment is a liquid crystal display device or an organic light emitting diode display device. Specifically, the display device in this embodiment can be any product or component with a display function, such as electronic paper, mobile phone, tablet computer, television, monitor, notebook computer, digital photo frame, and navigator.
[0071] Of course, the display device should also include other known structures, such as an array substrate, a backlight source, a color filter substrate, a packaging substrate, a power supply, a frame, and the like.
