Abstract:
1. A method of displaying a landscape mode image, comprising: selecting a video frame from M video frames received externally where M is greater than or equal to 2; storing the selected video frame into a video memory; masking only the selected video frame so as not to display the selected video frame in a display panel while the selected video frame is undergoing a process of being stored in the video memory; providing common voltage signal having a regular cycle of high and low voltage levels during periods in which the selected video frame is not masked, but during periods in which the selected video frame is masked maintaining the common voltage signal at a previous high or low voltage level through a next voltage level cycle, such that the selected video frame is not displayed in the display panel while the selected video frame is undergoing a process of being stored in the video memory; and displaying the selected video frame, which is stored in the video memory, in the display panel a predetermined number of times by cycling the voltage level of the common voltage signal the predetermined number of times after the selected video frame has been fully stored in the video memory.
