  • Patent number: 11187839
    Abstract: A display device including a display panel and an eyepiece is provided. An image realized by the display panel can be provided to a user by passing through the eyepiece. The display device can further include a front quarter-wave plate and a rear quarter-wave plate in order to increase the path of light traveling toward the eyepiece from the display panel. A barrier can be disposed between the front quarter-wave plate and the rear quarter-wave plate. The barrier can reflect or transmit the light traveling toward the eyepiece from the display panel on a region-by-region, so that the loss of light recognized by the user through the eyepiece can be minimized.

  • Patent number: 10739594
    Abstract: A display device having an eyepiece is provided. The display device includes a display panel and an eyepiece. An image realized by the display panel may be provided to user through the eyepiece. An optical module may be disposed between the display panel and the eyepiece in order to increase a path of light. For example, the optical module may include a front quarter-wave plate, a half-mirror, a rear quarter-wave plate and a linear reflective polarizing plate, which are sequentially stacked. A positive C-plate may be disposed in the optical module. The light travelling toward the eyepiece from the display panel may pass through the positive C-plate. Thus, in the display device, the overall thickness may be reduced, and the viewing angle may be increased.

  • Patent number: 10151930
    Abstract: Discussed is a stereoscopic image display device, which acquires design parameters based on the same aperture ratio and the same back distance regarding a single barrier cell when displaying different numbers of views using the barrier cell. The barrier cell, which includes first and second substrates opposite to each other, first electrodes arranged at an interval on the first substrate, a second electrode formed on the second substrate, and a liquid crystal layer between the first and second substrates, is driven to display different numbers of views. Assuming that a region of the barrier cell corresponding to a small view number is one unit, the number of unit drive regions divided in one unit is defined by K/A (where, ‘A’ is an aperture ratio of the barrier cell, and ‘K’ is {large view number/small view number}*n (‘n’ is a natural number between 1 and the small view number).
