A modified cutinase is disclosed. The cutinase has the modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of asparagine at position 181 with alanine, or substitutions of asparagine at position 181 with alanine and phenylalanine at position 235 with leucine. The modified enzyme has improved PET-hydrolytic activity, and thus, the high-activity PET hydrolase is obtained, and the industrial application value of the PET hydrolase is enhanced.

Cutinase having improved enzymatic activity

A display panel, a display device, and a driving method thereof are provided. A light-reflecting layer is disposed under a light-emitting layer of the display panel. When the display panel is under strong light, the light-emitting layer does not work, and the light-reflecting layer reflects natural light to achieve a full-color display. When the display panel is in low light or darkness, the light-emitting layer works, and the light-reflecting layer reflects the light emitted by the light-emitting layer to reduce a working intensity of the light-emitting layer and achieves the full-color display, thereby improving service life and visual effect of organic light emitting diodes (OLEDs).

Display panel, display device, and driving method thereof

A wearable device includes a strip-shaped substrate, a flexible display panel disposed on the strip-shaped substrate, and a flexible cover plate disposed on the flexible display panel. The wearable device can return from a bent state to a stretched state, so as to provide a user with a larger screen.
