Problems solved by technology

[0009] However, as in As shown in Figure 2, in the dot inversion driving mode, when the 1-to-6 multiplexer architecture is used, the junction of pixel B12 and R21 is not a complete dot inversion polarity distribution, and the pixel B12 is located Due to the uneven coupling capacitance effect, the display data of pixels B12 and R21 may interfere with each other (line mura)

Embodiment Construction

[0038] When the first multiplexer 1081 receives the first selection signal SEL1, it will select and output the first polarity data voltage to the pixels R11, B11 and G12 of the first pixel group; when it receives a second selection signal SEL2, The pixels G11, R12 and B12 of the first pixel group are selected to output the data voltage of the second polarity. When the second multiplexer 1082 receives the first selection signal SEL1, it selects and outputs the first polarity data voltage S1 to the pixels R21, B21 and G22 of the second pixel group, and is used for receiving the second selection signal SEL2 , select and output the second polarity data voltage S2 to the corresponding pixels G21, R22 and B22 of the second pixel group. Please note that the polarity of the first polarity data voltage S1 output when the first multiplexer 1081 receives the first selection signal SEL1 is different from the first polarity data voltage output when the first multiplexer 1081 receives the s...
