Claim 4:
5. A method for calibrating screen dimming of a display apparatus, wherein the display apparatus comprises a display module, a biosensor, an ambient-light sensor, and a display controller, and the ambient-light sensor detects ambient-light brightness and an ambient-light color temperature of the display apparatus, the method comprising:
utilizing the display controller to receive a video signal from a host, and displaying the video signal on the display panel;
when the biosensor detects that a user is located in front of the display apparatus, utilizing the biosensor to transmit an image-adjustment control signal to the display controller to control the display apparatus to enter an image-adjustment mode; and
when the display apparatus is in the image-adjustment mode, utilizing the display controller to adjust 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, and in the first dynamic brightness-adjustment mode, the method further comprises:
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; and
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.
