Classification: CPC G | IPC G

Claim 8:
9. A display apparatus, comprising:
a display module;
a biosensor;
an ambient-light sensor, configured to detect ambient-light brightness and an ambient-light color temperature of the display apparatus; and
a display controller, configured to receive a video signal from a host, and displays the video signal on the display module;
wherein when the biosensor detects that a user is located in front of the display apparatus, the biosensor transmits an image-adjustment control signal to the display controller to control the display apparatus to enter an image-adjustment mode,
wherein when the display apparatus is in the image-adjustment mode, the display controller adjusts screen brightness and a screen color temperature of the image signal displayed on the display module according to the ambient-light brightness and the ambient-light color temperature;
wherein the image-adjustment mode comprises a second dynamic brightness-adjustment mode, wherein in the second dynamic brightness-adjustment mode, the display controller further executes the following operations:
when the ambient-light brightness is between a first brightness and a second brightness, linearly adjusting the screen brightness of the display module at a first slope according to the ambient-light brightness;
when the ambient-light brightness is higher than or equal to the second brightness, linearly adjusting the screen brightness of the display module at a second slope according to the ambient-light brightness; and
when the ambient-light brightness is lower than the first brightness, linearly adjusting the screen brightness of the display module at a third slope according to the ambient-light brightness,
wherein the second brightness is higher than the first brightness, and the first slope, the second slope, and the third slope are greater than 0, and the second slope is greater than the first slope, and the first slope is greater than the third slope.
