Abstract: The disclosure provides trusted user interface display methods. One example method 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 client application (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 UI of the CA, where the TUI is adapted to the screen corresponding to the second display status.

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 includes drawing a first graph in a trusted execution environment (TEE). The method also includes displaying the first graph on a first layer in a display screen. The method further includes drawing a second graph in a rich execution environment (REE). The method additionally includes displaying the second graph on a second layer in the display screen. The first layer is located above the second layer. The first graph includes a transparent area and a non-transparent area. The non-transparent area includes content drawn in the TEE. A display area that is on the second graph and that corresponds to the transparent area includes content drawn in the REE. When the first layer and the second layer are overlapped for displaying, the transparent area does not shield the content drawn in the REE.
