Problems solved by technology
[0005] However, in order to make a double-layer retardation film of a quarter retardation film and a half retardation film, it is necessary to perform two retardation film coating and exposure processes after the alignment film printing and brushing process. Therefore, this kind of process method needs higher equipment cost and manufacturing time
Furthermore, since the cleaning steps such as washing with water cannot be performed after coating the quarter retardation film on the glass substrate and before coating the half retardation film, it is impossible to remove the 1 / 4 retardation film. particles or impurities
In other words, the cleanliness of the two phase difference film processes is not easy to control, which may easily lead to defects in the formed phase retarder, which will affect the quality of the three-dimensional display

Embodiment Construction
[0060] Figure 1A is a partial schematic view of a stereoscopic display according to an embodiment of the present invention. Figure 1B is a schematic cross-sectional view of a stereoscopic display according to the first embodiment of the present invention.
[0061] Please also refer to Figure 1A and Figure 1B , the stereoscopic display 100 is suitable for the viewer to watch while wearing glasses 102, wherein the glasses 102 have lenses 102L, 102R with different polarization properties. For example, when the observer wears glasses 102 to watch the stereoscopic display 100, through the lenses 102L and 102R with different polarization characteristics, the left and right eyes can respectively see the left-eye picture L and the right-eye picture R with different polarization directions, to form stereoscopic vision. In addition, the three-dimensional display 100 includes a liquid crystal display panel 110 , a polarizer 120 , a backlight module (not shown), a composite optical ...

The invention discloses a stereoscopic display which comprises a liquid crystal display panel, a polarizer, a composite optical film, a phase retardation plate and an adhesive layer. The liquid crystal display panel comprises a display surface and a back surface which is opposite to the display surface. The polarizer is configured on the back surface. The composite optical film is configured on the display surface. The composite optical film comprises a quarter-wave plate and at least one optical film, and the optical film is positioned between the liquid crystal display panel and the quarter-wave plate. The phase retardation plate comprises a plurality of phase retardation patterns which are separated mutually, and the phase retardation of each phase retardation pattern is lambda / 2. The adhesive layer is configured between the composite optical film and the phase retardation plate, and the phase retardation plate is connected with the quarter-wave plate through the adhesive layer.
Description
technical field [0001] The present invention relates to a display, and in particular to a three-dimension (3D) display. Background technique [0002] In recent years, with the continuous advancement of display technology, viewers have higher and higher requirements on the display quality (such as image resolution, color saturation, etc.) of the display. However, in addition to high image resolution and high color saturation, for viewers, whether the display can display stereoscopic images has also become one of the considerations in purchasing. [0003] In terms of appearance, stereoscopic display technologies can be broadly classified into stereoscopic, in which viewers need to wear specially designed glasses, and auto-stereoscopic, in which viewers directly watch with naked eyes. The glasses-type stereoscopic display can be divided into color filter glasses, polarizing glasses, and shutter glasses. The working principle of the glasses-type stereoscopic display is mainly ...
