Embodiment 1
[0064] Figure 6 It is a schematic structural diagram of the display device in this embodiment, and the demultiplexing circuit in this embodiment is a 1:3 type, that is, m=3.
[0065] Taking the switch group connected to the source line S1 and the corresponding multiple data lines D1, D2, D3 as an example, the switch group includes 3 strobe switches M1, M2, M3, and 3 strobe switches M1, M2, M3 The first channel end of the strobe switch M1, M2, and M3 are respectively connected to the three data lines D1, D2, and D3 in the same data line group, and the strobe switch M1 is connected to the source line S1. The control ends of the strobe switches M1, M2, and M3 are respectively connected to the gate lines CK1, CK2, and CK3, and gate parasitic capacitances Cgd1, Cgd2, and Cgd3 are generated between the control ends of the gate switches M1, M2, and M3 and the data lines D1, D2, and D3, respectively.
[0066] The compensation circuit includes a compensation drive circuit and the onl...
Embodiment 2
[0075]The difference between Embodiment 2 and Embodiment 1 is that in this embodiment, the turn-off time of the mth gate switch is not earlier than the time when the falling edge of the high-level phase of the scanning signal occurs in the current cycle. When 1≤i<m, the i-th compensation capacitor corresponding to the i-th data line is used to compensate the charge of the i-th gating parasitic capacitance; since the closing of the m-th gating switch affects the pixel unit connected to the m-th data line The pixel voltage has no effect, and the charge of the mth gate parasitic capacitance does not need to be compensated. Specifically, the compensation signal CK' has m-1 compensation rising edges in a high-level period, the first compensation rising edge, the second compensation rising edge, ..., the m-1 compensation rising edge are respectively connected with the first selected pass signal, the second strobe signal, ..., the m-1 th strobe signal corresponds. When 1≦i<m, the i-...
Embodiment 3
[0083] Figure 10 Shown is a schematic diagram of the waveforms of the scanning signals Gk, Gk+1, the gate signals CK1, CK2, CK3 and the compensation signal CK' in the display device of this embodiment. The difference between Embodiment 3 and Embodiment 2 is that the compensation signal CK' has one and only one compensation rising edge in a high-level period of the scanning signal Gk, and the compensation rising edge is not earlier than the m-1th strobe signal ( Figure 10 The middle is the falling edge of the gate signal CK2), not later than the falling edge of the high level phase of the scanning signal Gk.
[0084] The falling edge of the mth strobe signal is not earlier than the falling edge of the high-level phase, the closing of the mth strobe switch has no effect on the pixel voltage of the pixel unit connected to the mth data line, and the charge of the mth strobe parasitic capacitance No compensation required. Therefore, only setting one compensation rise in a high-...
