Liquid crystal display device and method for displaying a landscape mode image

摘要

A mobile LCD device controls a common voltage signal VCOM to effectively display a landscape mode image instead of using a separate integrated chip (IC). The LCD device utilizes a method of displaying a landscape mode image including selecting a video frame from M video frames received from an external source where M is greater than or equal to 2. The selected video frame is stored in a video memory. The selected video frame is masked so as not to display the selected video frame while the selected video frame is stored. The stored video frame is displayed a predetermined number of times while the selected video frame is not stored thereby effectively displaying the landscape mode image.
