PIXEL DRIVING CIRCUIT AND METHOD, ARRAY SUBSTRATE AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

A pixel driving circuit and method, an array substrate and a LCD apparatus, solve the problem of a deterioration of an image quality due to an insufficient charging to a pixel electrode when a refreshing frequency of the LCD is relatively high. The pixel driving circuit comprises n rows of scanning lines, where n is an integer and n≧3, and the pixel driving circuit further comprises a pre-charging unit connected to each row of scanning line, for activating the (i+2)th row of scanning line at the same time when the ith row of scanning line is activated, where i is an integer and 1≦i≦n−2. The array substrate comprises a number of pixel units distributed in a matrix, and further comprises the pixel driving circuit as described above. The LCD apparatus comprises the array substrate as described above. The pixel driving method is used for driving n rows of scanning lines, where n is an integer and n≧3, and activating the (i+2)th row of scanning line at the same time when the ith row of scanning line is activated, where i is an integer and 1≦i≦n−2.
