Phase retardation film and polarization type three-dimensional display containing same

Abstract

The invention discloses a phase retardation film which comprises a phase delay film, wherein a bonding layer and a stripping layer are sequentially arranged on the front side of the phase delay film; and a protection layer is arranged on the back side of the phase delay film. The invention also discloses a three-dimensional display and a three-dimensional liquid crystal display which respectively contain the phase retardation film. According to the retardation film and the polarization type three-dimensional display disclosed by the invention, the phase retardation film is attached to a transparent substrate and the transparent substrate to which the retardation film is attached is aligned with a liquid crystal panel. The structure of the phase retardation film for attaching is different from that of the traditional phase retardation film, so that the phase retardation film is positioned between the liquid crystal panel and the transparent substrate and the viewing angle of the polarization type three-dimensional display can be effectively increased; and aligning marks are arranged at the horizontal middle positions of the phase retardation film and the liquid crystal panel, so that the aligning error is reduced.

Description

technical field [0001] The invention relates to a retardation film and a polarized three-dimensional display containing the retardation film. Background technique [0002] In recent years, with the development of technology, 3D (three-dimensional) displays have become more and more popular, and major manufacturers have invested heavily in the field of stereoscopic displays to compete fiercely. At present, the 3D display technology for home use is glasses-type stereoscopic display technology, and the mainstream glasses-type stereoscopic display technology can be divided into shutter glasses (Shutter Glasses) and polarization (Polarization 3D). [0003] Shutter 3D achieves 3D effect by increasing the refresh rate of the picture. When the 3D signal is input to the display device, the image is divided into two frames by frame to form two sets of images corresponding to the left eye and the right eye, which are displayed in a continuous interlaced manner, and the signal transmit...

Problems solved by technology

Disadvantages of shutter-type 3D: very low brightness; glasses need to be charged, bulky and expensive; glasses flicker; images are prone to crosstalk

Due to the structural characteristics of the existing retardation film, when attached, the transparent substrate will be between the liquid crystal panel and the retardation film (such as Figure 5 shown), which increases the difficulty of alignment and affects the viewing angle: with Figure 5 Take the "viewing angle" marked above as an example, if the right eye glasses enter the left eye's viewing angle, you will see the light from the left eye pixel, and crosstalk will occur
