摘要： A display method and a terminal device are provided, so as to resolve a prior-art problem that CPU power consumption of the terminal device is relatively high because a display system of the terminal device processes three procedures in parallel in a Vsync period. The method is: determining, by the display system of the terminal device, a start moment of a first procedure in an (M+1) th Vsync period according to first processing duration of the first procedure in an M th Vsync period, so that the display system starts to execute a device display procedure before starting to execute the first procedure, the display system delays executing the first procedure in the (M+1) th Vsync period, so that a time required for processing three procedures in parallel in the (M+1) th Vsync period by the display system is reduced, and CPU power consumption of the terminal device is reduced.

摘要： An electronic device is described. The electronic device includes a memory. The electronic device also includes a very long instruction word (VLIW) circuit. The VLIW circuit includes an asynchronous memory controller. The asynchronous memory controller is configured to asynchronously access the memory to render different levels of detail. The electronic device may include a non-uniform frame buffer controller configured to dynamically access different subsets of a frame buffer. The different subsets may correspond to the different levels of detail.

摘要： In some examples, a device includes at least two light sources, buffer circuitry configured to receive a bit stream, and driver circuitry configured to receive the bit stream from the buffer circuitry and to drive the at least two light sources based on the bit stream. In some examples, the device further includes monitor circuitry configured to determine a voltage drop across each light source of the at least two light sources and snooping circuitry configured to read an inactive bit of the bit stream. In some examples, the snooping circuitry is further configured to read an active bit of the bit stream after reading the inactive bit and based on a value of the inactive bit and to cause the monitor circuitry to determine a voltage drop across a light source of the at least two light sources based on a value of the active bit.

摘要： A method for displaying an image on a display device (13) which is part of a display system also comprising a host device (11) configured to at least composite image data into an image frame and to transmit the image frame to a display controller (12) for display on the display device (13). The image has a predetermined portion, such as a cursor, having a Quality of Service (QoS) requirement higher than the rest of the image. Based (S31) on a performance level of the display system, compositing (S3Y4) the predetermined portion with the image data is composited into the image frame at the host device if the host device has sufficient performance capability to do so. If it is not determined that the performance level is sufficient, then the host device composites the image data without the predetermined portion and transmits it to the display controller. The host device also transmits (S3N4) information regarding the predetermined portion to the display controller independently of the image frame, so that the display controller can composite (S3N4b) the received image frame with the predetermined portion based on the information to produce the image for display.

摘要： Electronic Paper Displays can suffer from ghosting or previous images remaining partially visible after the display has updated to show a new image. A pseudo-random noise intermediate image is used to make the ghosting less visible to human observers. Further, other intermediate images can be used to convey visible information or to convey secret information, e.g. a watermark. A control signal for driving the bi-stable display from the current optical state to an intermediate state, then to a final optical state is also determined. In some embodiments, the intermediate state for each pixel is determined in a pseudo-random manner. The pseudo-random noise values are applied to the bi-stable display to remove noise and other artifacts from the end resulting images. The determined control signal is applied to the bi-stable display to drive the bi-stable to the intermediate state, then to the final optical state.

摘要： Methods and devices for reducing the power consumption of a frame buffer and timing controller of an electronic display are provided. By way of example, a method of operating an electronic display includes receiving image data from a processor of the electronic display, storing the image data to a buffer of the electronic display, reading the image data from the buffer to supply the image data to a column driver of the electronic display, determining whether an amount of image data stored in buffer is less than a threshold, and switching from reading the image data from the buffer to reading the image data directly from the processor when the amount of image data stored in buffer is less than the threshold.

摘要： Embodiments of the present disclosures provide a method, system and apparatus for transmitting intelligent information. When one frame of video data x is to be transmitted, a SDI sending terminal determines whether there is intelligent information satisfying a transmission condition; the transmission condition comprising that intelligent information is not transmitted and transmission of a frame of video data corresponding to the intelligent information is finished. If there is the intelligent information satisfying the transmission condition, the SDI sending terminal adds intelligent information y being one item of the intelligent information satisfying the transmission condition into a preset position of the video data x; and transmits the video data x having the intelligent information y. By using the solutions of the present disclosures, implementation costs are reduced and security is improved.
