Abstract: The present invention relates to liquid crystal display manufacturing technology. There provides a display drive signal compensating method, comprising the steps of: acquiring an original drive signal of every row of input pixels in a display; determining a position of the row of input pixels, based on the original drive signal; generating a compensation signal for compensating the original drive signal, based on a transmission line internal resistance at the position of the row of input pixels; and outputting a superposed signal obtained by superposing the compensation signal on the original drive signal to the row of input pixels. This method can compensates a voltage drop of the drive signal resulted by the transmission line internal resistance and thus improves the display effect. Meanwhile, there also provide a display drive signal compensating device for carrying out the abovementioned method, and correspondingly, a display comprising such device.
