Problems solved by technology

However, since TEE and Android are isolated systems, and there is usually no complex display system such as GPU in TEE, for TEE, TEE cannot perceive the screen status changes of folding screens.
This will cause the trusted user interface (TUI) of the TA corresponding to the CA to be unable to automatically adapt to the screen changes of the folding screen in scenarios such as mobile payment, which brings inconvenience to users

Abstract

The invention discloses a display method of a trusted user interface and electronic equipment, which are applied to the electronic equipment with a folding screen, and the method comprises the following steps: in response to a first operation of a user on the electronic equipment, changing the folding screen from a first display state to a second display state; displaying a user interface UI of the CA on a screen corresponding to the second display state; and in response to a second operation of the user on the UI of the CA, triggering to display a trusted user interface (TUI) corresponding tothe CA on the screen corresponding to the second display state, and the TUI being adapted to the screen corresponding to the second display state. According to the invention, the trusted user interface (TUI) of the TA corresponding to the CA can automatically adapt to the screen change of the folding screen, so that the user experience is improved.

Description

Technical field[0001]The present invention relates to the field of electronic equipment, and in particular to a display method of a trusted user interface (TUI) and electronic equipment.Background technique[0002]Nowadays, electronic devices such as mobile phones have been widely popularized and used. On the one hand, mobile payment or online banking or mobile banking have become important payment methods for people's daily consumption. Mobile payment refers to a service method in which users use mobile terminals (usually mobile phones) to pay for the goods or services they consume. While mobile payment brings convenience to users, its security has always been a concern. Mobile payment applications usually run in an open rich execution environment (Rich Execution Environment, REE). Applications in REE are also called client applications (CA). CA runs on general-purpose processors such asWait for the terminal operating system. This open environment provides a channel for information l...
