Abstract:
1. A driving device for a display for driving a pixel matrix containing N×M pixel units, comprising: a first vertical driver generating N first vertical driving signals in sequence each having a function period of T, each of said N first vertical driving signals being used to drive the first through the K-th pixel units on each row of said pixel matrix; a second vertical driver generating N second vertical driving signals in sequence each having a function period of T, each of said N second vertical driving signals being used to drive the (K+1)-th through the M-th pixel units on each row of said pixel matrix, wherein the M-th pixel unit is located at a right side of said pixel matrix; and a horizontal driver having M data lines providing data signals to said M pixel units on each row of said pixel matrix, respectively, wherein each of said second vertical driving signal has a start time ranged between that of a corresponding first vertical driving signal and (K/M)T, but said start time of said second vertical driving signal is not simultaneous to that of said corresponding first vertical driving signal, whereby said first and second vertical drivers extend a time period for charging said pixel units with said data lines from said horizontal driver to thereby avoiding mura effect at the right side of said pixel matrix otherwise caused by said horizontal driver under a low temperature condition.
