Problems solved by technology
When switching a monitor from portrait mode to landscape mode, the pixel pitch changes, resulting in a different viewing distance
[0006] In addition, because the parallax control element uses liquid crystals to form a light-shielding structure, the liquid crystals located at the edge of the electrode may have problems such as incomplete turning or uneven distribution, so it is easy to cause color difference due to different viewing angles of users.
Regardless of the viewing distance or chromatic aberration, it will cause inconvenience to users and affect the display quality of stereoscopic images

Description
technical field [0001] The present invention relates to a parallax control device and method, and more particularly to a parallax control device and method capable of presenting autostereoscopic images in two display modes. Background technique [0002] In general, 3D displays (three dimensional displays) can be divided into glasses-type 3D displays (also known as stereoscopic displays, stereoscopic displays) and naked-eye 3D displays. (Also known as autostereoscopic displays, autostereoscopic displays). With the glasses-type 3D display technology, the user must wear specially designed glasses such as shutter glasses, so that the user's left and right eyes receive different images respectively, and then perceive the stereoscopic image. Autostereoscopic display is to set special optical components inside the display device, such as parallax barrier, so that the display device can send different images to the left and right eyes of the user respectively, so that the user does...
