Abstract
An always-on display method includes, in response to a screen-off event, a first processor sends always-on display control information to a second processor and then sleeps. The always-on display control information includes an always-on display instruction. In response to the always-on display instruction, the second processor switches a screen-on interface to a first screen-off interface, and in response to a screen-off interface switching event, the second processor switches the first screen-off interface to a second screen-off interface, and the display content of at least one of the first screen-off interface or the second screen-off interface includes a dynamic picture.
Claims20
An always-on display method, comprising:
- in response to a screen-off event, sending, by a first processor of a terminal device and to a second processor of the terminal device, always-on display control information comprising an always-on display instruction and address information, and entering, by the first processor, a sleep mode after sending the always-on display control information, wherein the address information indicates a first location of a memory for storing each frame of a dynamic picture;
- switching, by the second processor in response to the always-on display instruction, from a screen-on interface to a first screen-off interface;
- and
- switching, by the second processor in response to a screen-off interface switching event, from the first screen-off interface to a second screen-off interface,
- wherein first display content of at least one of the first screen-off interface or the second screen-off interface comprises the dynamic picture and text information that is of a text display control and that changes with time, and
- wherein switching, by the second processor, the screen-on interface to the first screen-off interface or switching, by the second processor, the first screen-off interface to the second screen-off interface comprises:
- obtaining, by the second processor, frames of the dynamic picture from the memory based on the address information;
- obtaining, by the second processor, the text information;
- and
- combining, by the second processor, the frames with the text information for display on a display screen.

A terminal device, comprising:
- a first processor configured to, in response to a screen-off event:
- send always-on display control information comprising an always-on display instruction;
- and
- enter a sleep mode after sending the always-on display control information,
- a second processor configured to,
- receive the always-on display instruction from the first processor;
- in response to the always-on display instruction, switch from a screen-on interface to a first screen-off interface;
- and,
- in response to a screen-off interface switching event, switch from the first screen-off interface to a second screen-off interface,
- wherein first display content of at least one of the first screen-off interface or the second screen-off interface comprises a dynamic picture and text information that is of a text display control and that changes with time,
- wherein the always-on display control information further comprises address information that indicates a location of a memory for storing each frame of the dynamic picture, and wherein the second processor is further configured to:
- obtain frames of the dynamic picture from the memory based on the address information;
- obtain the text information;
- and
- combine the frames with the text information for display on a display screen.
12 more elements
A terminal device, comprising:
- a first processor configured to, in response to a screen-off event:
- send always-on display control information comprising an always-on display instruction to a second processor;
- and enter a sleep mode after sending the always-on display control information to the second processor,
- wherein the second processor is configured to:
- in response to the always-on display instruction, switch from a screen-on interface to a first screen-off interface;
- and
- in response to a screen-off interface switching event, switch from the first screen-off interface to a second screen-off interface,
- wherein first display content of at least one of the first screen-off interface or the second screen-off interface comprises a dynamic picture and the first screen-off interface according to a first always-on display rule, wherein the second processor obtains the second screen-off interface according to a second always-on display rule, and the first display content of the at least one of the first screen-off interface and the second screen-off interface further comprises text information that is of a text display control and that changes with time wherein either:
- the first screen-off interface comprises the text information, and the first always-on display rule comprises an instruction to continuously display the text information and the second screen-off interface comprises a second interface and a third interface, second display content of the second interface comprises the text information and the dynamic picture, second display content of the third interface comprises the text information, and the second always-on display rule comprises switching to display the third interface after the second interface is displayed for a predetermined duration;
- or
- the first screen-off interface comprises a second interface and a black screen interface, the second interface comprises the text information, and the first always-on display rule comprises switching to the black screen interface after the second interface is displayed for the predetermined duration, and the second screen-off interface comprises a third interface and the black screen interface, second display content of the third interface comprises the text information and/or the dynamic picture, and the second always-on display rule comprises switching to the black screen interface after the third interface is displayed for the predetermined duration.
