摘要： A system for updating an electrophoretic display of an electronic paper device (EPD) has a display driving system comprising a display manager, a compositor, a bounding box list producer, a display controller and a memory storing a bounding box list, a transfer matrix buffer, waveforms and subframes. The display driving system receives one or more display requests from one or more input devices and applications. The display driving system transforms the display requests into bounding boxes and transition matrices of pixel values. The display driving system collapses overlapping bounding boxes into non-overlapping bounding boxes. The display driving system generates subframes using the bounding boxes, the transition matrices and waveforms containing voltage information. The subframes are used to drive the electrophoretic display to display an image.

摘要： A system and a method are disclosed for fast pen tracking a low latency display updates on an electronic paper display. Pen input information is received on an electronic paper display that updates at a predetermined display update rate. A line drawing module of the electronic paper display driver determines at least one pixel to activate based on the received pen input information. The at least one pixel is updated independent of the display update rate of the electronic paper display. Active pixel state information is maintained separately for each pixel in real time until the pixel update is complete and the pixel is deactivated. In some embodiments, a future pixel to activate is determined based on the received pen input information. The future pixel is deactivated if pen input information is not received on the activated pixel for a predetermined amount of time.

摘要： A system for displaying video on electronic paper displays to reduce video playback artifacts comprises an electronic paper display, a video display driver, a video transcoder, a display controller, a memory buffer and a waveforms module. The video display driver receives a re-formatted video stream, which has been processed by the video transcoder, from the memory buffer. The video display driver directs the video transcoder to process the video stream and generate pixel data. The video display driver loads waveforms into the frame buffer and updates display commands repeatedly to activate the display controller until the end of the video playback. The video display driver directs copying video frames sequentially one by one from the memory buffer to the frame buffer in real time during the video playback. The video transcoder receives a video stream for presentation on the electronic paper display and processes the video stream generating pixel data that is provided to the display controller. The present invention also includes a method for displaying video on an electronic paper display.

摘要： A system for displaying video on electronic paper displays to reduce video playback artifacts comprises an electronic paper display, a video transcoder, a display controller and a waveforms module. The video transcoder receives a video stream on for presentation on the electronic paper display. The video transcoder processes the video stream and generates pixel data that is provided to the display controller. The video transcoder adapts and re-encodes the video stream for better display on the electronic paper display. In one embodiment, the video transcoder includes one or more of the following processes: encoding the video using the control signals instead of the desired image, encoding the video using simulation data, scaling and translating the video for contrast enhancement and reducing errors by using simulation feedback, past pixels and future pixels. The present invention also includes a method for displaying video on an electronic paper display.

摘要： A system and a method are disclosed for updating a bi-stable display includes a framebuffer for storing waveforms for each pixel individually. The system includes determining a current state of a pixel of the bi-stable display; determining a desired state of the pixel of the bi-stable display; and updating the pixel by applying a determined control signal to the pixel to drive the pixel from the current state to the final state. Updating each pixel occurs independently of the other pixels of the bi-stable display.

摘要： A device to translate an input pixel value to an output pixel value for a current pixel includes a diffusion block to produce a diffusion error to add to the input pixel value to produce a diffused pixel value. In addition, the device includes a feedback modulation block to generate a threshold value, the threshold value determined using a value of an earlier output pixel value, the earlier output pixel value occurring at a predetermined number of pixels prior to the current pixel. Furthermore, the device includes a quantizer to compare the diffused pixel value to the threshold value and based on the comparison to select a value for the output pixel value.
