Patent number: 9405406Abstract: An image pickup device capable of stably detecting an object irrespective of use conditions while reducing manufacturing costs is provided. When illumination light from a backlight is emitted to a proximity object from an I/O display panel, an electric charge is accumulated in image pickup pixels in accordance with total light amount, including reflected light originating from the backlight and external environment light. Moreover, when the illumination light is not emitted, a discharging electric charge is released from the image pickup pixels in accordance with the amount of environment light. Thereby, an environment light component is subtracted from an image pickup signal obtained from each of the image pickup pixels, so object information about the proximity object is obtained without influence of the environment light. Moreover, in a light reception drive circuit, fewer frame memories for producing a picked-up image from the image pickup signal are necessary.Type: GrantFiled: May 6, 2015Date of Patent: August 2, 2016Assignee: Japan Display Inc.Inventors: Tsutomu Harada, Yoshiharu Nakajima, Michiru Senda, Kazunori Yamaguchi, Mitsuru Tateuchi, Ryoichi Tsuzaki, Toshikazu Maekawa
