Abstract: In an embodiment, an electronic device includes a display and processing circuitry. The display includes a plurality of pixels arranged in a plurality of rows, wherein a first grouping of the plurality of rows displays image content during a first portion of an image frame, and wherein a second grouping of the plurality of rows displays image content during a second portion of the image frame. The processing circuitry is operatively coupled to the display and determines a velocity associated with the image content displayed by the first grouping of the plurality of rows moving across the display and adjusts a position of the image content displayed by the second grouping of the plurality of rows during the second portion of the image frame.

Abstract: An organic light-emitting diode (OLED) display panel and a display device are provided. The OLED display panel includes a substrate, a thin-film transistor device layer, a light-emitting device, a passivation layer, a planarization layer, a level-raised layer, a protruding platform, an auxiliary electrode, and an undercut channel. The protruding platform is disposed directly above the level-raised layer. The auxiliary electrode includes a contact portion and a step portion, and the step portion is located at a vertical level higher than a vertical level of the contact portion. An orthographic projection of the undercut channel on the substrate and an orthographic projection of the level-raised layer on the substrate are spaced apart from each other.

Abstract: The present disclosure provides a frequency converter. The frequency converter includes a box body and a bottom box. A bottom portion of the box body is fixedly connected with a top portion of the bottom box. A top portion of a left side of the box body and a bottom portion of the left side of the box body are fixedly connected to a respective fan. A top portion of a left side of an inner wall of the box body and a top portion of the left side of the inner wall of the box body are fixedly connected to a respective annular plate. One end of an output shaft of each fan is fixedly connected to a rotating rod. One end of each rotating rod away from the fan passes through the box body and extends to an interior of the box body.

Abstract: The disclosure relates to the technical field of toys, and provides a non-electric toy transmission system, to resolve a prior-art technical problem that an electric toy transmission mechanism has high use costs and a short service life. Technical solutions in the disclosure are as follows: The non-electric toy transmission system includes an instruction apparatus, an execution apparatus, a pipeline, and a transmission medium, where the instruction apparatus and the execution apparatus are connected by the pipeline, and the instruction apparatus, the execution apparatus, and the pipeline are filled with the transmission medium; and the instruction apparatus is capable of being triggered to enable the transmission medium in the instruction apparatus to enter the execution apparatus through the pipeline, and the execution apparatus completes, under pressure of the transmission medium, an action designed for a toy.

Abstract: The present application relates to the field of immersed tube jointing, and more particularly relates to a post-grouting method for an immersed tube joint base. The post-grouting method includes the following steps: before locked backfilling of immersed tubes to be implanted, disposing a grouting tube capable of outputting solidifiable slurry in a furrow below immersed tubes; and after the locked backfilling, grouting the immersed tubes by using the grouting tube. For the purposes of adjusting postures and heights of the immersed tubes in case of abnormal settlement during installation, solving the problems on the stabilities and the service lives of immersed tube joints due to settlement of gravel mattresses or a geologic structure thereunder after installation, and enabling the immersed tubes to achieve a better bearing effect on a load during use, the present application provides the post-grouting method for the immersed tube joint base.
