Gradation adjustment method and electronic device

An electronic device, wherein the electronic device comprises a processor and a memory, the memory is coupled to the processor, the memory is configured to store computer program code, the computer program code comprises computer instructions, and when the processor executes the computer instructions, the electronic device is caused to perform:

• displaying a first window at a first moment, wherein the first window is a focus window at the first moment, and a gradation of the electronic device at the first moment is a first gradation;
• and
• setting a second window as a focus window at a second moment in response to a first operation input by a user, wherein the gradation of the electronic device is a second gradation after the second moment, the second gradation is lower than the first gradation, and the second moment is later than the first moment.

A computer-readable storage medium, wherein the computer-readable storage medium stores a computer program or instructions, and when the computer program or the instructions are run on a computer, the computer is caused to perform:

• displaying a first window at a first moment, wherein the first window is a focus window at the first moment, and a gradation of the electronic device at the first moment is a first gradation;
• and
• setting a second window as a focus window at a second moment in response to a first operation input by a user, wherein the gradation of the electronic device is a second gradation after the second moment, the second gradation is lower than the first gradation, and the second moment is later than the first moment.
