Referring to fig. 8, fig. 8 is a schematic layout diagram of another virtual scan line in fig. 7.
As shown in fig. 8, at least one dummy scan line DG is disposed at a position of the opposite substrate 10d corresponding to the non-display area, the dummy scan line DG includes a first sub-dummy scan line DG1 and a second sub-dummy scan line DG2, and the dummy scan lines DG are disconnected from any point to form the first sub-dummy scan line DG1 and the second sub-dummy scan line DG2. The first sub-dummy scan line DG1 is connected to the first conductor 133A and is connected to the first dummy scan driving unit 132A via the first conductor 133A, and the second sub-dummy scan line DG2 is connected to the second conductor 133B and is connected to the second dummy scan driving unit 132B via the second conductor 133B. The virtual scan signal output by the first virtual scan driving unit 132A is transmitted to the first sub-virtual scan line DG1 via the first conductor 133A, and the virtual scan signal output by the second virtual scan driving unit 132B is transmitted to the second sub-virtual scan line DG2 via the second conductor 133B.
In an exemplary embodiment, the first sub dummy scan line DG1 and the second sub dummy scan line DG2 are connected to the ground terminal at break points for transmitting the received dummy scan signal to the ground terminal.
The first sub dummy scanning line DG1 and/or the second sub dummy scanning line DG2 is provided with a temperature-sensitive resistor R, and the resistance value of the temperature-sensitive resistor R increases with an increase in temperature, and decreases with a decrease in temperature. By setting the temperature sensing resistor R, the temperature change condition around the virtual scanning driving line can be detected in real time, and the current of the virtual scanning signal can be adjusted according to the temperature change.
Referring to fig. 9, fig. 9 is a schematic diagram of the layout of the electrical conductor in fig. 5.
As shown in fig. 9, the array substrate 10c is further provided with a plurality of clock signal lines 14, the scan driving unit 131 and the dummy scan driving unit 132 are connected to the clock signal lines 14, the scan driving unit 131 is configured to output a scan signal according to the clock signal, and the dummy scan driving unit 132 is configured to output a dummy scan signal according to the clock signal.
The conductor 133 is disposed on a side of the clock signal line 14 adjacent to the opposite substrate 10d, and the dummy scan driving unit 132 is connected to the conductor 133 and to the dummy scan line DG disposed in the opposite substrate 10d through the conductor 133. A heat sink 15 is further disposed between the clock signal line 14 and the conductor 133, and the heat sink 15 is covered on the clock signal line 14 adjacent to the dummy scan driving unit 132, so as to transfer heat in the clock signal line 14 to the opposite substrate 10d through the conductor 133, thereby dissipating heat from the clock signal line 14. And because the virtual scanning line DG is provided with the temperature sensing resistor R, the temperature sensing resistor R can adjust the load in the virtual scanning line DG according to the heat sink 15, thereby reducing the current of the virtual scanning signal and balancing the heating condition of the clock signal line 14.
By arranging the virtual scanning line DG on the opposite substrate 10d, overlapping of the virtual scanning line DG and the data line can be avoided, thereby reducing the protection line against electrostatic discharge, and simultaneously reducing the coupling capacitance between the virtual scanning line DG and the data line, thereby reducing the load of the data line, improving the charging rate of the pixel unit, and since the virtual scanning line DG is arranged on the opposite substrate 10d, the space occupation of the array substrate 10c can be reduced, which is beneficial to the arrangement of a narrow frame. And by setting the temperature sensing resistor R, the load in the virtual scanning line DG can be adjusted according to the temperature change, so that the load when the virtual scanning line DG transmits the virtual scanning signal is reduced while heat dissipation is ensured, thereby reducing the delay of the scanning driving unit 131 outputting the scanning signal and improving the display effect.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
