摘要： Embodiments of the application provide a shift register comprising a shift signal generating circuit and at least two time-sharing controlling circuits. The shift signal generating circuit may be configured to generate a shift signal. Each of the time-sharing controlling circuits comprises a first driving sub-circuit and a second driving sub-circuit, wherein the first driving sub-circuit is configured to enable the time-sharing controlling circuit to output the shift signal during the preset period, and the second driving sub-circuit is configured to enable the time-sharing controlling circuit to output an invalid signal during the non-preset period. During a driving cycle, the first driving sub-circuits in each of the at least two time-sharing controlling circuits are turned on sequentially, so that each of the at least two time-dividing controlling circuits outputs the shift signal sequentially.

摘要： A substrate, a mask, a display panel and a display device are provided. The substrate includes a base substrate and a color resistance layer on the base substrate. The substrate has a display area and a non-display area. The color resistance layer in the non-display area includes a weakening unit for weakening or disconnecting connection between the color resistance layer in the non-display area away from the display area and the color resistance layer in the display area. During the development and washing process of the substrate, even if the color resistance layer in the non-display area is peeled off, the color resistance layer in the display area will not be peeled off together, which helps to ensure the safety and reliability of the color resistance layer in the display area.
