Display system with adjustment for brightness perceived by user's eyes

A display adjustment method of an electronic apparatus, wherein the electronic apparatus comprises a display panel, a timing controller circuit and a processing circuit, the display adjustment method comprising:

• processing, by the timing controller circuit, frame data to be displayed by the display panel;
• analyzing, by the processing circuit, an image including a face of a person to obtain adjustment information with respect to the light perceived by the face;
• comparing an average luminance value of a face area with a threshold, so as to obtain a comparison result used to correspondingly adjust the frame data or at least one display characteristic associated with the frame data, wherein the threshold is an average luminance value of the image;
• and
• correspondingly adjusting, by the timing controller circuit, the frame data or the at least one display characteristic associated with the frame data according to the adjustment information.

A display system, comprising:

• a first electronic apparatus, comprising a processing circuit configured to analyze an image including a face of a person to obtain adjustment information with respect to the light perceived by the face;
• and
• a second electronic apparatus, comprising a display panel and a timing controller circuit, wherein the timing controller circuit is coupled to the display panel to process frame data to be displayed by the display panel, and the timing controller circuit correspondingly adjusts the frame data or at least one display characteristic associated with the frame data according to the adjustment information,
• wherein the processing circuit comprises:
• a comparison circuit, configured to compare an average luminance value of a face area in the image with a threshold, so as to obtain a comparison result used to control the timing controller circuit to correspondingly adjust the frame data or the at least one display characteristic associated with the frame data, wherein the threshold is an average luminance value of the image.
