Method for controlling a liquid crystal display module to show interlaced picture data thereon

摘要

A method for controlling a liquid crystal display (LCD) module to show interlaced picture data thereon includes the step of providing a data field of the interlaced picture data, which data field includes a series of line picture data, to the LCD module. Twin line clock pulses are then provided to the LCD module to control latching of each line picture data thereby. Finally, a frame start pulse is provided to the LCD module whenever a first one of the line picture data is provided to the LCD module. The width of the frame start pulse is varied so that the LCD module can show the first one of the line picture data on a first even line thereof when the data field is an even data field and on a first odd line thereof when the data field is an odd data field. The twin line clock pulses and the frame start pulse ensure that the line picture data of the even and odd data fields are shown alternately and respectively on even and odd lines of the LCD module.
