Abstract: The present invention provides an on-line method for stabilizing surface compressive stress of chemically-tempered glass, which comprises the steps of: placing glass to be tempered together with a stabilizer in a tempering furnace containing a molten salt bath for glass tempering; and after reacting at a temperature for a period of time, removing the glass and the stabilizer from the tempering furnace. The stabilizer is capable of chemically reacting with impurity ions in the molten salt bath for glass tempering, to remove the impurity ions in the molten salt bath. Therefore, the presence of the stabilizer allows the impurity ion content in the molten salt bath for glass tempering to be stable without gradual accumulation.

Abstract: Embodiments of the present disclosure disclose a pixel structure, a mask plate, an organic electroluminescent display panel and a display device. The pixel structure comprises: a plurality of pixel units arranged in array, each pixel unit comprising four sub-pixels arranged diagonally and having the same shape and size; wherein colors of the four sub-pixels in each pixel unit are different from each other; colors of two adjacent sub-pixels in any two adjacent pixel units are same. The above pixel structure provided by embodiments of the present disclosure may enable the color of any sub-pixel in a pixel unit to be same as the colors of three sub-pixels that are located in other three pixel units adjacent to this pixel unit respectively and are symmetric with this sub-pixel relative to a same point.

Abstract: Disclosed are a method for eliminating self-magnetization of a mask, a method for manufacturing a substrate and a mask testing device. The mask may include a plurality of metal stripes spaced from each other. The method may include a step of: energizing the mask, so as to enable the plurality of metal stripes to carry like charges, thereby separating every metal stripe from other adjacent metal stripes bonded together.
