Problems solved by technology
[0009] It can be concluded from the three schemes that the first scheme is to use a PDLC panel and a larger collimator lens. Using the first scheme will make the cost higher and the device volume will be larger; the second scheme is to use a polarizer Converting the light source emitted by the backlight unit into polarized light, the second option will cause a great loss of light efficiency of the device, especially in 2D display mode, which is not conducive to 2D display; the third option uses OLED panels, which will make the cost higher

The invention provides a 2D / 3D switchable liquid crystal display apparatus and a display method thereof. The 2D / 3D switchable liquid crystal display apparatus comprises a display panel of a transmission type display device and a 2D / 3D switchable module group providing backlight for the display panel, wherein the 2D / 3D switchable module group comprises a 2D backlight module group, a light guide plate on the 2D backlight module group, side-inlet type LED lamp strips on the two opposite sides of the light guide plate, and a plurality of microstructures are arranged on the light exit surface of the light guide plate. The 2D / 3D switchable liquid crystal display apparatus when serves as an integrated imaging 3D display device overcomes the limitation of limited depth of a 3D display mode. The integrated imaging 3D display modes include a real mode and a virtual mode. The 2D / 3D switchable liquid crystal display apparatus when serves as a 2D display device has high quality 2D display effect and has high light efficiency.
Description
technical field [0001] The invention belongs to the technical field of integrated imaging three-dimensional display, and in particular relates to a 2D / 3D switchable liquid crystal display device and a display method thereof. technical background [0002] Integrated imaging is a true three-dimensional display technology that uses microlens arrays to record and reproduce three-dimensional space scenes. It is a naked-eye three-dimensional display technology with full parallax, full-color 3D images, and quasi-continuous viewpoints. Integrated imaging is considered ideal. One of the naked-eye three-dimensional display devices. Due to the characteristics of the specific 3D image of integrated imaging such as small depth range, narrow viewing angle, low resolution of 3D image, and depth inversion of 3D image, at the same time, it is difficult to obtain the 3D display source required for integrated imaging, so 2D / 3D switchable integrated imaging 3D display technology is one of the...
