Reprojection and wobulation at head-mounted display device
A head-mounted display device including one or more position sensors and a processor. The processor may receive a rendered image of a current frame. The processor may receive position data from the one or more position sensors and determine an updated device pose based on the position data. The processor may apply a first spatial correction to color information in pixels of the rendered image at least in part by reprojecting the rendered image based on the updated device pose. The head-mounted display device may further include a display configured to apply a second spatial correction to the color information in the pixels of the rendered image at least in part by applying wobulation to the reprojected rendered image to thereby generate a sequence of wobulated pixel subframes for the current frame. The display may display the current frame by displaying the sequence of wobulated pixel subframes.
Display device with image shift
A display device includes a controller and a display panel. The controller receives original image data and output a display image signal. The display panel receives the display image signal and displays a display image corresponding to the display image signal. The controller includes an image shift controller and a memory. The image shift controller generates shifted image data by modulating the original image data to shift the display image sequentially along a preset shift path on the display panel. The memory stores a shift path value indicating a distance by which the display image has been shifted on the preset shift path. The image shift controller generates the display image signal by processing the shifted image data. When the display device is powered on, the image shift controller generates shifted image data corresponding to a shift path value stored in the memory.
Display device, control method therefor, and head-mounted virtual display device
A display device includes a base substrate, a display panel, and a moveable structure located between the base substrate and the display panel, fixedly connected to the display panel and slidably connected to the base substrate; the display panel includes pixel areas and non-pixel areas between the pixel areas; in displaying phase, the moveable structure is configured to control the display panel to perform reciprocating motion with a preset cycle, the distance that the display panel moves in a single direction in the preset cycle is smaller than or equal to the width of a non-pixel area in the single direction, the preset cycle is the time required for the display panel to perform reciprocating motion once, and the time that the display panel moves in the single direction in the preset cycle is equal to the time that an image of the display panel is refreshed once.
Increasing resolution and luminance of a display
The disclosed system modifies luminance of a display associated with a selective screen. The display provides a camera with an image having resolution higher than the resolution of the display by presenting multiple images while the selective screen enables light from different portions of the multiple images to reach the camera. The resulting luminance of the recorded image is lower than a combination of luminance values of the multiple images. The processor obtains a criterion indicating a property of the input image where image detail is unnecessary. The processor detects a region of the input image satisfying the criterion, and determines a region of the selective screen corresponding to the region of the input image. The processor increases the luminance of the display by disabling the region of the selective screen corresponding to the region of the input image.
Rendered optical super resolution display
A method includes rendering, by at least one processor, a first sub-frame of an image, where the first sub-frame includes a first subset of pixels of the image. The method includes displaying the first sub-frame on a display. The method also includes rendering, by the at least one processor, a second sub-frame of the image, where the second sub-frame includes a second subset of pixels of the image, and where the second sub-frame is shifted a half-pixel diagonally from the first sub-frame. The method also includes displaying the second sub-frame on the display after displaying the first sub-frame, where the display is optically shifted a half-pixel diagonally to display the second sub-frame.
LIQUID CRYSTAL PROJECTOR
When, in a liquid crystal projector, optical responsiveness of a liquid crystal panel corresponding to G is better than optical responsiveness of a liquid crystal panel corresponding to R, a display control circuit performs a tr correction and a tf correction of overdrive processing for R, and performs only the tr correction of the overdrive process for G, and does not perform the tf correction for G. The display control circuit performs a black floating process for R, G, and B.
DISPLAY DEVICE AND METHOD OF DRIVING THE SAME
A display device includes a display panel and an image processor. The display panel includes pixels, each pixel among the pixels including sub-pixels. The image processor is configured to process image data for image display via the display panel. An arrangement of sub-pixels of a pixel in an odd-numbered pixel column of the display panel is different from an arrangement of sub-pixels of a pixel in an even-numbered pixel column of the display panel. The image processor includes an edge determiner and a sub-pixel renderer. The edge determiner is configured to determine an edge from the image data. The sub-pixel renderer is configured to perform sub-pixel rendering on pixel data about sub-pixels configured to display a same color in adjacent pixels in the odd-numbered pixel column or the even-numbered pixel column located at the edge.
SYSTEMS AND METHODS FOR PROVIDING IMAGE MOTION ARTIFACT CORRECTION FOR A COLOR SEQUENTIAL (CS) DISPLAY
Systems and methods for providing image motion artifact correction for a color sequential (CS) display in a display system in a vehicle. The system includes a processor operationally coupled to a source of a coherent RGB image frame, a source of a line of sight (LOS) motion rate, and the display system, the processor configured to, calculate a sub-frame (SF) timing rate for the CS display; unpack the coherent RGB image frame into a Red, a Green, and a Blue frame; calculate a red, a green, and a blue pixel shift, as a function of a LOS rate change; apply the red pixel shift to the Red frame, the green pixel shift to the Green frame, and the blue pixel shift to the Blue frame, thereby creating modified RGB sub-frames; and re-packing the modified RGB sub-frames into a modified coherent RGB image frame for the CS display.
Shift register having isolation circuits, light-emitting control circuit, and display panel
The present disclosure relates to a shift register for a display panel. The shift register may include an input terminal, an output terminal, an input unit, an output unit, a first control unit, a second control unit, and a first isolation unit. The output unit may be configured to transmit a first level or a second level to an output terminal based on levels of a first node and a second node.
DISPLAY DEVICE AND DISPLAY METHOD
A display device and a display method are provided. The display device includes a bendable display screen and a retractable device. The bendable display screen can move relative to a housing of the display device using the retractable device. When a static image is displayed, a display area of the static image in the bendable display screen is changed by movement of the bendable display screen and adjustment of the display position without the premise of changing a position of the static image relative to the housing of the display device.
