    摘要: The present disclosure provides a printing mask and a method of printing an adhesive pattern with the printing mask. The printing mask includes: a screen including: an annular permeable region through which an adhesive permeates; and a barrier region which surrounds the annular permeable region and stops a permeation of the adhesive through the barrier region, the annular permeable region including an adjustment sub-region configured to increase a permeability of the adhesive, and the barrier region including barrier sub-regions respectively located on an inner side and an outer side of the corresponding adjustment sub-region; a first film covering a side of the barrier region; and a second film covering sides of the barrier sub-regions facing away from the first film.

    摘要: A frame sealing glue includes a frame sealing glue body having an inner layer portion (211) and an outer layer portion (212). The frame sealing glue further includes an intermediate film layer (22) disposed between the inner layer portion (211) and the outer layer portion (212), and a plurality of enclosed spaces (P) are formed by the intermediate film layer (22) and the inner layer portion (211) or the outer layer portion (212) of the frame sealing glue body. A display panel and a display device are also provided. By means of the frame sealing glue, the display panel and the display device according to the embodiments of the present disclosure, it avoids a leakage phenomenon when the frame sealing glue is broken at different points, thereby increasing ability of the frame sealing glue for resisting external atmospheric pressure.

    摘要: Embodiments of the present disclosure provide a test circuit, a test method, a display panel and a display apparatus. Each of the signal input terminals may input a plurality of signals in a time division multiplexed manner, and in turn may be controlled by the corresponding switches to form a plurality of signal lines, a signal flow of the plurality of signal lines are totally different from each other under control of the switches. For example, one of the signal lines may function as a signal input line, and the other one of the signal lines may function as a signal input line for other specific testing, such as aging process so as to input signals different from the normal turn-on state signals. Consequently, by controlling the corresponding switches through the control signal terminals so that different input signals pass through different signal lines into the display panel to meet testing requirements of normal turn-on state testing, aging process and so on for the display panel. With respect to the prior art, the testing signals may be input without passing through a shift register unit, which avoids damage of a specific testing signal such as aging signal on the shift register unit and ensure a normal displaying function of the display panel.
