  • Patent number: 10942407
    Abstract: The present invention is intended to control the color temperature of white exhibited by a liquid crystal display device. White is produced when light waves emitted through pixels associated with three colors of red, green, and blue have maximum intensities. The amounts of light emitted through the respective pixels are controlled by differentiating the shapes of the pixel electrodes disposed at the respective pixels from one another. Thus, the color temperature of white is controlled. Otherwise, the shapes of interceptive films disposed at the respective pixels are differentiated from one another in order to control light waves emitted through the respective pixels. Thus, the color temperature of white is controlled. The interceptive film may be shaped like the pixel electrode. Otherwise, the interceptive film may be realized with an interceptive pattern other than that of the pixel electrode or one of openings bored in a black matrix.

  • Patent number: 10210833
    Abstract: A display device includes a primary display area which comprises a first display area and a second display area which is unique from the first display area, a control unit configured to display an image in the primary display area, an image signal generating unit configured to generate display data based on externally input image data for a single image. The image signal generating unit comprises a memory which stores display-position information indicating a display location of a first image displayed in the primary display area. The display data comprises first and second display data to be displayed in the first display area and the second display area, respectively. The first display data is generated based on the externally input single image data and the display-position information. The control unit is configured to cause a first image to be displayed in the first display area based on the first display data.
