Abstract: A two-dimensional code processing method and a device. The method includes: obtaining, by a first electronic device, two-dimensional code information displayed by a second electronic device; obtaining first scenario information, where the first scenario information is scenario information related to the first electronic device; determining two-dimensional code data and second scenario information based on the two-dimensional code information, where the second scenario information is scenario information related to the second electronic device ; and when determining that the first scenario information and the second scenario information meet a preset condition, performing, by the first electronic device, preset processing on the two-dimensional code data. The scenario information of the two electronic devices that need to perform two-dimensional code interaction is compared, and further, two-dimensional code verification is completed.

Abstract: An image display method provided is applicable to the electronic device that includes a trusted execution environment (TEE) and a rich execution environment (REE). The TEE draws a first graph, and displays the first graph on a first layer in a display screen; and the REE draws a second graph, and displays the second graph on a second layer; and the first graph includes a transparent area and a non-transparent area, the non-transparent area includes content drawn by the TEE, a display area that is on the second graph and that corresponds to the transparent area includes content drawn by the REE, and when the first layer and the second layer are overlapped for displaying, the transparent area does not shield the content drawn by the REE. Richness of a trusted user interface (TUI) is improved by using a powerful drawing capability of the REE.

Abstract: This application discloses a trusted user interface display method. The method is applied to an electronic device having a foldable screen, includes: changing the foldable screen from a first display status to a second display status in response to a first operation performed by a user on the electronic device; displaying a user interface UI of a CA on a screen corresponding to the second display status; and triggering to display a trusted user interface TUI corresponding to the CA on the screen corresponding to the second display status in response to a second operation performed by the user on the of the CA, where the TUI is adapted to the screen corresponding to the second display status. In this application, the trusted user interface (TUI) of a TA corresponding to the CA can automatically adapt to a screen change of the foldable screen, thereby improving user experience.
