Abstract: The present disclosure provides a viewing angle switching structure, a display device and a viewing angle switching method. The viewing angle switching structure includes a plurality of viewing angle switching units corresponding to pixels on a display panel. Each viewing angle switching unit includes: an accommodation cavity; a first solution layer and a second solution layer in the accommodation cavity, a liquid interface being formed between the first and the second solution layers; and an electric field driving unit configured to generate a driving electric field to be applied to the accommodation cavity. The first solution layer has a refractive index different from the second solution layer. The first solution layer includes a transparent conductive solution and the second solution layer includes a transparent non-conductive solution. A shape of the liquid interface between the first and the second solution layers is changeable under the effect of the driving electric field.

Abstract: Embodiments of the present disclosure provide a method for fabricating a display panel, a display panel and a display apparatus. The display panel has a display area and an encapsulation area surrounding the display area. In the method, an encapsulating adhesive is formed in the encapsulation area. A portion of the encapsulating adhesive at a corner of the encapsulation area has a recess facing toward the display area. Next, cutting lines are arranged on the encapsulating adhesive. The cutting lines at the corner of the encapsulation area extend into the recess. Next, the display panel is cut along the cutting lines. The method, the display panel and the display apparatus eliminate negative effects of encapsulation reliability test failure due to a portion of the encapsulating adhesive at a corner of the encapsulation area being prone to be cracked, and thus the yield of cutting the display panel is enhanced.
