摘要： An intersection blind-guiding system includes: a blind-guiding terminal, a plurality of blind road sensors, and a processor configured to be coupled to the blind road sensors. The blind-guiding terminal includes a blind-guiding terminal sensor configured to transmit a sensing signal. The blind road sensors include at least one first blind road sensor and at least one second blind road sensor. The blind road sensors are configured to separately receive the sensing signal transmitted by the blind-guiding terminal sensor, and upload corresponding sensing information. The processor is configured to receive the sensing information uploaded by the blind road sensors, locate a current position of a blind person carrying the blind-guiding terminal, determine a direction in which the blind person previously traveled, determine geographic distribution information of the current position of the blind person, and send a command carrying the geographical distribution information.

摘要： Disclosed are a display substrate and a manufacturing method therefor, and a display panel and a display device. The arrangement of a first isolation portion and a second isolation portion at least disconnects a first isolated portion from one of a second isolated portion and a third isolated portion; therefore, the effect of isolating a cathode can be enhanced when an isolated layer is the cathode multiplexed into a self-capacitance electrode; and when the isolated layer is an inorganic film encapsulation layer contained in a bezel area, cracks generated by cutting or for other reasons may be prevented from extending to a display area.
