    Abstract: Embodiments of the present invention disclose a triboelectrification device and a display device. The triboelectrification device includes at least one layered electricity generating assembly that is stacked, the at least one layered electricity generating assembly each comprising an electrode layer, an insulating layer, a metal layer and an elastomer; the electrode layer, the insulating layer, and the metal layer are arranged in sequence from above downwards, the elastomer is disposed between the electrode layer and the metal layer and is located at at least one side of the insulating layer. The electrode layer and the insulating layer are brought into contact with each other to be rubbed against each other by applying a pressure to the electrode layer, and the electrode layer and the insulating layer can be separated from each other by springing back of the elastomer, such that the electrode layer and the insulating layer are repeatedly brought into contact with each other to be rubbed against each other time after time, thereby continually generating positive and negative charges on the metal layer and the electrode layer respectively and thus achieving usage of electric energy into which energy generated by friction is converted.

    Abstract: The disclosure relates to a type of virtual reality glasses used to alleviate a view's feeling of fatigue when he or she wears virtual reality glasses for viewing. The virtual reality glasses comprise a housing, a display device, and an optical imaging device disposed within the housing. The optical imaging device is located between the display device and the human eyes. In addition, the virtual reality glasses further comprise a dimming device disposed on the housing wall. When the viewer feels tired after a long time watch through the virtual reality glasses, the viewer may control the dimming device to adjust the ambient light in the virtual reality glasses to improve the background environment inside the virtual reality glasses, thereby alleviating the viewer's feeling of fatigue resulted from viewing through virtual reality glasses worn by him or her.

    Abstract: A method for determining location of a short-circuit point in a raster device comprises: applying a first DC voltage signal to a common electrode layer in the raster device; applying a second DC voltage signal to only first transparent electrodes in the raster device, or a second DC voltage signal to only second transparent electrodes in the raster device, or a second DC voltage signal to both the first transparent electrodes and the second transparent electrodes in the raster device, an absolute value of a difference between a voltage value of the first DC voltage signal and a voltage value of the second DC voltage signal being not lower than a liquid crystal deflection threshold voltage value (501); acquiring grayscale values of corresponding display areas in the raster device and determining the location of the short-circuit point according to the acquired grayscale values (502). The method provides a solution for determining the location of the short-circuit point which is in contact with the first transparent electrode and the second transparent electrode simultaneously.
