Embodiment 1
[0049] A first aspect of the embodiments of the present invention provides a drive circuit 2 for a display panel.
[0050] like figure 1 and Figure 12 As shown, the drive circuit 2 of the display panel includes a gate drive circuit 10 and a source drive circuit 20, the gate drive circuit 10 is used to connect with n scan lines of the display panel 1, and the source drive circuit 20 includes a controller 23, The logic switch circuit 22 and the source driver 21, the source driver 21 includes m signal output terminals, and the m signal output terminals are connected to the m columns of data lines of the display panel 1 through the logic switch circuit 22;
[0051] The controller 23 is triggered by the gate driving circuit 10 to scan in the forward direction row by row and outputs the first control signal to the logic switch circuit 22;
[0052] The gate driving circuit 10 scans in reverse row by row and triggers and outputs the second control signal to the logic switch circuit...
Embodiment 2
[0071] This embodiment is embodied on the basis of the first embodiment, such as Figure 11 As shown, in one embodiment, the logic switch circuit 22 includes m logic switches K1, each logic switch K1 includes a first signal input terminal, a second signal input terminal, a third signal input terminal and a signal output terminal, each The signal output terminals of the logic switch K1 are respectively connected to a column of data lines of the display panel 1 , and the first signal input terminal, the second signal input terminal and the third signal output terminal of each logic switch K1 are respectively spaced from the source driver 21 in sequence. The three signal output terminals of i are connected.
[0072] During forward scanning, the signal output end of the logic switch K1 is connected to one of the data lines of the display panel 1, and the first signal input end is connected to the signal output end of the corresponding serial number of the source driver 21. During ...
Embodiment 3
[0075] This embodiment is embodied on the basis of the first embodiment, such as Figure 12 As shown, the gate driving circuit 10 includes a gate driver 11 and a feedback circuit 12, and the feedback circuit 12 is respectively connected with the gate driver 11 and the controller 23;
[0076] a gate driver 11, configured to output a forward line scanning signal to the n-row scanning lines of the display panel 1 to perform forward progressive scanning when receiving the forward scanning control signal; and
[0077] When receiving the reverse scan control signal, output the reverse row scan signal to the n rows of scan lines of the display panel 1 to perform reverse progressive scan;
[0078] The feedback circuit 12 is used for feeding back the forward scan control signal and the reverse scan control signal to the controller 23 .
[0079] In this embodiment, the gate driver 11 is used for outputting line scanning signals line by line according to the received scanning control si...
