Abstract: Embodiments of the present disclosure provide a method for controlling a converter and a converter system. The method includes obtaining voltage signals indicating phase voltages of three phases at AC side of a converter, determining, based on the voltage signals, carrier signals of a three-phase switching branches of the converter, wherein carrier signals of two of three phases have the same phase with each other and have a different phase from a carrier signal of the rest phase of the three phases, and magnitude of a phase voltage of the rest phase is between the phase voltages of the two phases, and generating, based on the determined carrier signals and modulation wave signals of the three-phase switching branches, control signals of the three-phase switching branch.

Abstract: A panel light-on apparatus, panel light-on testing system and panel light-on testing method are provided. Wherein, the panel light-on apparatus comprises a supporting member; a workbench provided on the supporting member to hold and secure a tested panel; and a display panel located at bottom of the workbench to provide a backlight to the tested panel and display a predetermined image, wherein the predetermined image is projected to the tested panel and overlapped with an image displayed by the tested panel. Through adding the display panel, not only a backlight for the tested panel, but also real-time displaying defect images are provided to assist in determining the cause of the defect; and the display range of the display panel can be adjusted in accordance with the sizes of different tested panels to achieve the purpose of light-proofing of other non-test panel areas on the workbench.

Abstract: The disclosure discloses a displacement-type scanning stereoscopic display apparatus including: a protective shell, projection screens, light shielding cases, two rotary shafts, conveyor belts, at least two scattering plates; and the rotary shaft is uniformly rotated at a high speed, the scattering plates fixed on the conveyor belt periodically receives image slices projected from the projection screens, and when the scattering plates are moved from one of the rotary shaft positions to the other rotary shaft position, a scanning display of the image slice corresponding to the stereoscopic image is completed. According to the embodiment of the disclosure, by the rotation of the rotary shaft, the moving screen can be moved uniformly, and the display effect and the service life of the stereoscopic display apparatus can be remarkably improved.

Abstract: A method of weakening line defects of a display device is provided. Firstly, an abnormal phenomenon of the display device is detected, and abnormal pixels corresponding to the abnormal phenomenon are confirmed; secondly, display information outputted to each of the abnormal pixels is cleared; and finally, a light diffusion glue is coated on positions of the polarizing sheet corresponding to the abnormal pixels and two sides thereof, such that the abnormal pixels are covered by display information of two sides of the abnormal pixels by the light diffusion glue.

Abstract: There provides an optimization method of thickness uniformity of alignment film, and the optimization method includes: providing a thin film transistor (TFT) array substrate on which a passivation layer is deposited; coating a photoresist on the passivation layer; dividing the TFT array substrate into different regions, and exposing, developing and etching the photoresist in different regions by respectively using a half tone mask and a common mask; removing the photoresists and depositing an ITO film after etching; etching the ITO film to obtain the TFT array substrate in which upper surfaces of the ITO film and the passivation layer are at a same level; and coating an alignment film on the upper surfaces of the ITO film and the passivation layer. Since the upper surfaces of the ITO film and the passivation layer are at the same level, the thickness of the alignment film coated thereon is uniform.
