Classification: CPC G | IPC G

Claim 0:
1. 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 first dynamic brightness-adjustment mode, wherein in the first dynamic brightness-adjustment mode, the display controller further executes the following operations:
when the distance is longer than a first distance, increasing the screen brightness of the image signal displayed on the display module;
when the distance is between the first distance and half of the first distance, maintaining the screen brightness of the image signal displayed on the display module;
when the distance is shorter than half of the first distance, reducing the screen brightness of the image signal displayed on the display module by a first brightness ratio;
when the distance is shorter than a second distance, reducing the screen brightness of the image signal displayed on the display module by a second brightness ratio,
wherein the first distance is greater than 2 times the second distance, and the second brightness ratio is greater than the first brightness ratio;
wherein the first distance corresponds to the user's optimal horizontal field of view (FoV), and the second distance corresponds to the user's maximum horizontal FoV.
