1. A display panel comprising: several pixel groups arranged in a matrix which consist of N-row×M-column subpixels, gate lines connected to subpixels of respective rows, and data lines connected to subpixels of respective columns; wherein N is a positive integer larger than 2, M is a positive integer larger than 1, and in one and the same pixel group, subpixels of the same column comprise subpixels of at least two colors,
the display panel further comprising: a plurality of operational amplifiers corresponding to respective data lines, respective operational amplifiers being connected to corresponding data lines via corresponding switching devices, respectively, and a control unit connected to respective switching devices, wherein, the number of operational amplifiers corresponding to each data line is equal to that of color types of subpixels connected to the data line, and one operational amplifier corresponds to subpixels of one color, in a plurality of operational amplifiers corresponding to each data line, respective operational amplifiers are used to output data signals to subpixels of corresponding colors connected to the corresponding data line successively according to a scanning order of the gate lines; the control unit is used to, for subpixels of the m-th column of the display panel, control one of the switching devices connected to the data line that is connected to the subpixels of the m-th column to be in conducting state when the gate line of the n-th row is scanned, and the switching device in conducting state is a switching device connected to the operational amplifier for outputting data signals to the subpixels of the n-th row. |
