20140198192 | DISPLAY DEVICE AND DISPLAY CONTROL METHOD - To appropriately prevent the occurrence of a burn-in phenomenon during a display of a video in which an OSD screen is superimposed on a video screen. By appropriately moving the position for displaying an OSD screen when the OSD screen is displayed on a video screen in a superimposed manner, a burn-in phenomenon is prevented from occurring in a menu background area of the OSD screen or a boundary portion between a menu background area and a menu phrase. For example, each time the OSD screen is displayed, the OSD screen is moved by one pixel and then displayed. Movement of the display position of the OSD screen is implemented by an instruction from an OSD display position control unit | 07-17-2014 |
20140198193 | HEAD MOUNT DISPLAY AND DISPLAY CONTROL METHOD - To appropriately prevent a burn-in phenomenon when a still image such as an OSD screen is displayed on a display panel. When a menu screen is displayed on a video screen in a superimposed manner, a menu phrase in at least one of a left-eye video and a right-eye video is deleted on a menu background area. A time period in which a brightness difference between still pixels in a boundary between a menu background area and a menu phrase remains large is reduced, and thus the occurrence of the burn-in phenomenon can be prevented. However, the menu background area is constantly displayed without being deleted, so that screen flickering does not occur. | 07-17-2014 |
