`ABSTRACT ABSTRACT
`
`(57) (57)
`
`A liquid crystal display driving device of matrix structure A liquid crystal display driving device of matrix structure
`
`type and its driving method are disclosed in the present inven(cid:173)type and its driving method are disclosed in the present inven(cid:173)
`
`tion. The driving device consists of a group of thin film tion. The driving device consists of a group of thin film
`
`transistors with matrix array, a plurality of gate lines and a transistors with matrix array, a plurality of gate lines and a
`
`plurality of data lines. The object of increasing response plurality of data lines. The object of increasing response
`
`speed can be accomplished by the different arrangement of speed can be accomplished by the different arrangement of
`
`gate lines and data lines and the different connection between gate lines and data lines and the different connection between
`
`each thin film transistor and the gate and data lines. The each thin film transistor and the gate and data lines. The
`
`driving method for the said driving device includes: each pair driving method for the said driving device includes: each pair
`
`of gate lines in the display panel are simultaneously and of gate lines in the display panel are simultaneously and
`
`orderly turned on at different time of driving transistor, and orderly turned on at different time of driving transistor, and
`
`the different driving voltages are orderly applied to the thin the different driving voltages are orderly applied to the thin
`
`film transistors connected to the gate lines. The structure and film transistors connected to the gate lines. The structure and
`
`method can suit for picture treating of various displays such method can suit for picture treating of various displays such
`
`as liquid crystal display, organic light-emitting diode (OLED) as liquid crystal display, organic light-emitting diode (OLED)
