A colour washout compensation method and apparatus, which relate to the technical field of display. The method comprises: when receiving target input grey scale data of a target sub-pixel point in a current row, a colour washout compensation apparatus acquires the uplink output grey scale data of the previous row of sub-pixel points on the same display line with the target sub-pixel point, performs, according to the target input grey scale data and the uplink output grey scale data, digital-analog conversion on target output grey scale data obtained by an inquiry done in combination with a target correspondence table and which corresponds simultaneously to the target input grey scale data and to the uplink output grey scale data, so as to obtain the target voltage of the target sub-pixel point, and finally adjusts, according to the target voltage, the colour displayed by the target pixel point where the target sub-pixel point is located. The solution can solve the colour washout problem of a liquid crystal display panel caused by the impedance difference of a fan section, thereby improving the display effect. |
