LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DISPLAYING A LANDSCAPE MODE IMAGE
First Claim
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 while the selected video frame is stored; and
displaying the stored video frame a predetermined number of times while the selected video frame is not stored.

Abstract
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.

9. A timing controller for displaying a landscape mode image, said controller comprising:
-
a video memory configured to store a video frame selected from a plurality of video frames received from an external source; and a driver controller coupled to said video memory, said driver controller configured to control a common voltage signal so as not to display the video frame while the video frame is stored into said video memory, said driver controller further configured to repeatedly display the video frame a predetermined number of times while the video frame is not stored. - View Dependent Claims (10, 11, 12, 13, 14)

15. A mobile liquid crystal display (LCD) device for displaying a landscape mode image, comprising:
-
a display panel having a plurality of gate lines and a plurality of data lines; a source driver coupled to said display panel and configured to drive the data lines; a gate driver coupled to said display panel and configured to drive the gate lines of the display panel; a driving voltage generator coupled to said gate driver and said display panel, said driving voltage generator configured to provide a common voltage signal to said display panel and further configured to provide a control voltage to the gate driver; and a timing controller configured to control a drive timing of the source driver, the gate driver and the driving voltage generator, said timing controller having a video memory configured to store a video frame that is selected from a plurality of video frames received from an external source and a driver controller configured to control a common voltage signal so as not to display the video frame while the video frame is stored into the video memory, and configured to repeatedly display the video frame a predetermined number of times while the video frame is not stored. - View Dependent Claims (16, 17, 18, 19, 20)
