[0035] Example 1
[0036] like image 3 A liquid crystal display panel assembly provided in this embodiment is shown, which includes: a display panel 100 , a display area 110 arranged on the display panel 100 , a fan-out area 120 arranged on the display panel 100 , and a display area 120 arranged on the display panel 100 The package on the edge has the thin film on chip 130 of the driver IC 140 and the PCB 150 .
[0037] The display area 110 is provided with a plurality of first data lines 111, and the fan-out area 120 is provided with a plurality of second data lines 121 with various lengths connected to the first data lines 111; In the near area, the length of the second data line 121 is shorter, and the second data line 121 is laid according to a straight path, so as to reduce the width of the edge of the display panel 100 as much as possible, which better realizes the display device. narrow border design. The thin film on chip 130 is used to connect the display panel 10...

[0043] Embodiment 2
[0044] In this embodiment, on the basis of the above-mentioned first embodiment, the adjustable resistance groups 145 are grouped again, that is to say, the adjustable resistance group includes a plurality of sub-adjustable resistance groups, so that each sub-resistor group can be adjusted. A group of sub-resistor groups can be adjusted to a uniform resistance value, so that there is no need to set different resistances for the output terminals of each functional circuit, and only a group of resistors with the same resistance value is needed to reduce the connection (the output terminal of the functional circuit to the first terminal). The impedance difference between the connections between the data lines 111) is enough. This setting can basically eliminate the signal delay or the signal delay is very weak, and the influence on the display effect can be ignored. This setting method can greatly reduce the cost. decrease.

[0045] Embodiment 3
[0046] like Figure 4 As shown, the difference from the first embodiment is that in this embodiment, the resistor 144 can be directly integrated in the driver IC 140 , the third data line 131 is coupled to the output end of the driver IC 140 through the resistor 144 , and the third data line 131 is connected to the panel. the second data line connection of the fan-out area. This method does not need to set up a special control circuit to control the resistance, but the driver IC of this method can only be applied to one type of panel. Similarly, a plurality of resistor groups with the same resistance value can be used to form a group of resistance groups, and a plurality of groups of resistance groups with different resistance values can be integrated in the driving IC 140 . In this way, there is no need to set different resistors for each output end of the driver IC140. It is only necessary to reduce the impedance difference through a set of resistor...
