The invention discloses an electric corrosion preventing bearing, and relates to a bearing. Electric corrosion is easily produced due to potential difference between an inner ring and an outer ring of a rotating bearing, so the current flowing surface of the bearing is concavo-convex, and the service life of the bearing is shortened. The electric corrosion preventing bearing comprises an inner ring, an outer ring and a rolling body positioned between the inner ring and the outer ring. The electric corrosion preventing bearing is characterized in that: a conductive electric ring is arranged between the outer ring and the inner ring, the elastic ring is contacted with the outer ring and the inner ring, and the bearing is provided with a limiting part for positioning the elastic ring. The elastic ring keeps a contact state with the outer ring and the inner ring by means of elasticity; the bearing has simple structure and is easy to manufacture, so the bearing has low cost and is suitable for large-batch production; and the bearing has good reliability, and the voltage difference between the inner ring and the outer ring of the bearing is reduced to zero so that the service life of the bearing is prolonged.

The device comprises the following components of: a suspension potential conductor; a conductor connecting piece which is connected to the suspension potential conductor; a discharge electrode which is connected with the conductor connecting piece through an insulating piece; a high-potential conductor, wherein the high-potential conductor is connected to the high-voltage overhead line, a discharge gap being formed between the high-potential conductor and the discharge electrode; and a discharge channel is formed between the high-potential conductor and the discharge electrode by using a phase voltage from the high-voltage overhead line, so that power can be supplied to anexternal load connected with the discharge electrode and the conductor connecting piece based on electric power generated by the discharge channel. According to the device of the invention, the discharge gap is formed between the discharge electrode and the high-potential conductor, and the potential difference between the discharge electrode and the high-potential conductor causes air gap breakdown of the discharge gap, so that charges induced on the discharge electrode are transferred to generate broadband current, and the broadband current is transmitted to the external load through the conductor connecting piece and the discharge electrode so as to supply power to the external load.

The invention provides a display panel and a display device, and belongs to the technical field of display. In the display panel, each of a first pixel circuit located in a first display area and a second pixel circuit located in a second display area comprises a driving circuit with two grid electrodes, and one grid electrode is used for receiving a power supply signal. The potential of the power supply signal received by the grid electrode of the driving circuit in the first pixel circuit is different from that of the power supply signal received by the grid electrode of the driving circuit in the second pixel circuit. Therefore, the independent control of the characteristics of the transistor included in the driving circuit in the first pixel circuit and the characteristics of the transistor included in the driving circuit in the second pixel circuit is realized. Therefore, in different scenes of the first pixel circuit and the second pixel circuit, the source driving circuit transmits data signals with small potential difference to the two pixel circuits, so that two light-emitting elements driven by the two pixel circuits have the same light-emitting brightness. Correspondingly, the working power consumption of the source electrode driving circuit is low.
