Patent number: 10242428Abstract: The present disclosure is related to a method for driving a transparent display device. The method includes extracting a corneal reflection image, generating a flat target image, generating a background image, and displaying the background image on a transparent display panel. The corneal reflection image includes a target image formed by projecting, on a cornea of a user, a display area of the transparent display panel divided into the display area which displays a display image and transmits light reflected from a background and a non-display area adjacent to the display area. The flat target image is generated by correcting the target image distorted by a curved shape of the cornea. The background image is formed by removing the display image from the flat target image.Type: GrantFiled: February 28, 2017Date of Patent: March 26, 2019Assignee: Samsung Display Co., Ltd.Inventors: Yukiyoshi Sasao, Masatoshi Sonoda, Takahisa Yamamoto
