Abstract: A display processing device includes a display device interface and a processing unit. The processing is configured to transition at least a first component of the display processing system into a low-power state in response to an active region of a first video frame of a plurality of video frames having completed. A second component of the display processing device is configured to maintain a temporal count value corresponding to a current frame line of the plurality of video frames, and further to generate a first signal in response to the temporal count value corresponding to a first trigger value. The first signal causes the at least first component to transition out of the low-power state.

Abstract: A method, a device, and a non-transitory computer readable medium for performing dithering on an L bit long input data are presented. An M bit long random data is generated, wherein M is a number of least significant bits of the input data. An M bit long frame counter value is added to the random data. The input data is rounded up to L-M most significant bits when the M least significant bits of the input data is greater than the sum of the frame counter value and the random data. The input data is truncated to the L-M most significant bits when the M least significant bits of the input data is less than or equal to the sum of the frame counter value and the random data.

Abstract: A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring then the transmission guide rod retracts into the casing and closes.
