Embodiments relate to systems and methods for generating address information to translate the order in which memory locations are accessed in a video buffer, to maintain a desired orientation in a rotated display. A video buffer is filled with display data to drive a CRT, LCD, or other display screen, starting with the upper-left corner. When the user rotates the display screen, the display screen continues to scan from the same starting corner, resulting in a misaligned orientation. In embodiments, a correct orientation can be automatically generated by determining a scan direction for the rotated display. The physical location of the new logical starting pixel is determined, and the rows and columns of the display image are rendered in a revised logical order which compensates for the amount and direction of rotation.

The present invention provides a system which integrates unique lighting technologies, switching systems, mounting systems, information delivery systems and power supply systems within a support such as vehicular wheel to provide an advanced, high quality visual display apparatus in various surfaces of rotation. A displayed image may be three dimensional. These technologies, and their many unique applications, provide for a novel and useful series of video display devices that are small, lightweight, efficient and can have the capability of producing a clear, bright, high definition image that is equivalent to that of a modern day TV or high quality computer monitor.

The invention discloses a video display system capable of improving display resolution. The video display system comprises a driving module capable of supporting multiple resolutions and multiple video formats, a data storage module for caching video images and a display module for displaying the images, wherein the driving module decomposes each frame of received original video image into four video images of which the resolution is lower than that of the original video image, the pixel resolution of the display module and the resolution of the decomposed video image are kept consistent, andfour decomposed video images are displayed on a display screen in a dynamic combination mode according to different sub-pixel units within one frame of time of an original video image. According to the invention, higher visual resolution can be obtained under the condition that the power consumption and the size of the display screen are not obviously increased, the purpose of displaying images with higher resolution by using a screen with lower resolution can be realized, the actual display effect superior to that of a screen with lower resolution is obtained, and the method is particularly suitable for application scenarios with higher requirements on display area and power consumption.

The invention discloses a projection screen annotation method and system. The method comprises the following steps of: dividing a first terminal into a plurality of canvas layers which comprise a first canvas layer and a second canvas layer; obtaining coordinate information in real time, drawing a first annotation handwriting on the first canvas layer according to the coordinate information, directly displaying the first annotation handwriting, and simultaneously transmitting the coordinate information to a second terminal through a network; converting the coordinate information to obtain coordinate conversion information, and drawing a second annotation handwriting in the second terminal according to the coordinate conversion information; obtaining and storing a screenshot image of the current screen on the second terminal, transmitting the screenshot image to the first terminal by the network, and displaying the screenshot image on the second canvas layer; and erasing the first annotation handwriting drawn on the first canvas layer, and displaying the screenshot image of the first terminal. According to the method and system disclosed by the invention, the problem of inconvenient operation caused by annotation handwriting display lag due to the influences of wireless environment and hardware resource is solved, so that the users cannot feel the bluntness of the writing and then the user experience is enhanced.

An image display method of an Android platform based display device includes: monitoring the state of a mouse coupled to the display device to acquire a corresponding mouse event; creating a mouse cursor layer according to the acquired mouse event, and reporting a processing request of the mouse cursor layer to an upper level; and having a processor of the display device enable an auxiliary processing thread in response to the processing request of the mouse cursor layer to process the processing request of the mouse cursor layer so as to display a corresponding mouse cursor on a display screen of the display device. The image display method and the display method of the present invention effectively increase the response speed for a mouse cursor event, preventing lagging in displaying a mouse cursor and enhancing user experience.
