Abstract

A display method and a display device are provided. The display method may be applied to a display device having a lens unit and a display unit for normal display, and may include steps of: detecting a first distance between the lens unit and the display unit; calculating correction information according to the first distance and transmitting the correction information to the display unit; and displaying a corrected image by the display unit according to the correction information, so that the corrected image is converged into eyes of a user via the lens unit, wherein the corrected image is obtained by correcting an original image according to the first distance.

Dependent claims

A display method for a display device having a lens unit and a display unit, comprising:

detecting a first distance between the lens unit and the display unit;
calculating correction information according to the first distance and transmitting the correction information to the display unit;
and
displaying a corrected image by the display unit according to the correction information, so that the corrected image is converged into eyes of a user via the lens unit, wherein the corrected image is obtained by correcting an original image according to the first distance.

1 more element

A display device comprising:

a lens unit configured to converge light emitted from a display unit into eyes of a user;
an adjustor configured to adjust a first distance between the lens unit and the display unit;
a distance measurement unit configured to detect the first distance;
and
a corrector configured to calculate correction information according to the first distance and transmit the correction information to the display unit so as to control the display unit to display a corrected image according to the correction information, wherein the corrected image is obtained by correcting an original image according to the first distance.
