Abstract: Disclosed herein is a bidirectional magnetic levitation brush motor device, including a motor housing, a motor shaft and an end cover, wherein the end cover is arranged at a bottom end of the motor housing, shaft holes are formed in axes of the motor housing and the end cover, the motor shaft is arranged between the two shaft holes, bearings are arranged at junctions of the motor shaft with the motor housing and the end cover, the end of the motor shaft that is away from the end cover extends out of the motor housing, and a transmission connection shaft is arranged at a top end of the motor shaft. With regard to the present invention, movement transmission is achieved by means of an electromagnetic effect, and mounting of elastic structures such as a torsion bar and the like is no longer needed.

Abstract: Disclosed herein is a bidirectional magnetic levitation acoustic motor device, including a motor housing and a motor shaft, wherein the motor shaft is arranged at an axis of the motor housing, an end cover is arranged at a bottom end of the motor housing, shaft holes are formed in axes of the motor housing and the end cover, and the motor shaft penetrates through the two shaft holes. With regard to the invention, movement transmission is achieved by means of an electromagnetic effect, and mounting of elastic structures such as a torsion bar and the like is no longer needed, so that on one hand, the situation that the service life of a motor is short due to the fact that the elastic structures are prone to damage during usage is avoided, and on the other hand, the motor in a unit volume can transmit torque in a larger value.

Abstract: A liquid crystal display including a pixel array, multiple control lines and a driving unit is provided. The pixel array has multiple pixels. The control lines are coupled to the pixels. The driving unit drives the pixel array via the control lines. Of the pixels coupled to the same control line, the number of image-dithering compensated pixels with positive polarity is equal to the number of image-dithering compensated pixels with negative polarity when the pixel array is driven.
