ABSTRACT:
In a matrix display apparatus for displaying video signal of two or more different standards, such as PAL and NTSC standards comprising a display panel (10), for example, a liquid crystal display panel, having a row and column array of picture elements (12), a column driver circuit (22) for sampling lines of an applied video signal (25) and supplying data signals to the panel (10), a row driver circuit (20) for scanning the rows of picture elements in turn, and a control circuit (21) controlling the timing of the operations of the row and column driver circuits (20,22), the row driver circuit (20) is controlled by signals ST,CLK so as to scan the rows of picture elements at a rate which is a function of the number of rows in the panel (10) and the field period of the applied video signal. Using a row scanning rate which is substantially equal to the number of rows divided by the active field period of the applied video signal, all rows of the panel are addressed within the field period of different standards of applied video signal and video picture fills the available display area.
