Abstract
The utility model provides a patterned retardation film applied to a three-dimensional display, which comprises a substrate, a patterned retardation layer and a micro-louver structure. The patterned phase difference layer is positioned on the surface of the substrate and is provided with a plurality of first retardation micro-structure regions and a plurality of second retardation micro-structure regions. In this way, images displayed through the display can be divided into left-eye images and right-eye images, so that the three-dimensional display effect is formed. The micro-louver structure is arranged between the substrate and the patterned retardation layer and is positioned at the junctions of all the first retardation micro-structure regions and all the second retardation micro-structure regions. According to the technical scheme of the utility model, by means of the patterned retardation film with the micro-louver structure, the crosstalk condition of images on the display when spectators are looking at the display at an upward large visual angle and a downward large visual angle can be relieved. Meanwhile, when spectators are looking squarely at the display, the image effect is not influenced by the brightness of the display at all.
Description
Technical field
The utility model relates to a kind of patterning phase retardation film that is applied to three dimensional display, refer in particular to a kind of patterning phase retardation film with micro-shutter, while making to watch three dimensional display, can reduce the crosstalk phenomenon (crosstalk) of vertical direction image, and in positive apparent time, do not affect the brightness of display.
Background technology
Existing diaphragm type polarization three dimensional display is comprised of the image data of two groups of different visual angles, and wherein, a group image data is corresponding to left eye visual angle, and another group image data is corresponding to right eye visual angle.When playing 3-dimensional image, by structure of polarized light, adjust the phase settings of image output, the left eye that makes to put on the spectators of specific structure of polarized light glasses only can be seen the image data corresponding to left eye visual angle, and right eye only can be seen the image data corresponding to right eye visual angle, by this, spectators can produce stereoscopic vision in brain.
As shown in Figure 1, for the polarization image that shows that right and left eyes is different, the display panel of known three dimensional display adopts the patterning phase retardation film 400 of striped formula (stripe) staggered designs conventionally, the pixel that screen can be showed is divided into odd-numbered line (odd line) and even number line (even line) is distinguished two of corresponding left and right, for instance, as the odd-numbered line pixel L1 in the first figure, L2 and L3 can distribute to left eye, and even number line pixel R1, R2 and R3 can distribute to right eye, and form the images of left and right eyes visual area of these two groups of different visual angles.Spectators wear specific structure of polarized light glasses again, make the output display image of odd-numbered line pixel and the output display image of even number line pixel have different phase places and be sent to respectively right and left eyes.Thus, spectators just can experience stereo display effect.
The image data of these two groups of different visual angles that form due to patterning phase retardation film 400 is for adopting the horizontal direction of interlace mode to arrange, therefore, when spectators' eye position vertically changes with respect to display, or because of height, view and admire angle when different, between the images of left and right eyes visual area image data of these two groups of different visual angles, can crosstalk, affect the comfort level of spectators' vision and the image quality of display video picture.As shown in Figure 2, patterning phase retardation film 400 comprises base material 100 and patterning phase separation layer 40, and patterning phase separation layer 40 is positioned at the surface of base material 100, and has a plurality of first-phase potential difference microstructured area L and a plurality of second-phase potential difference microstructured area R.When spectators put on corresponding anaglyph spectacles in viewing location B, can see the left vision district 5LJi right vision district 5R in 30 transmissive display panel of backlight respectively at right and left eyes, then form three-dimensional image by first-phase potential difference microstructured area L and the second-phase potential difference microstructured area R of patterning phase retardation film 400; But when the larger viewing location A of vertical angle, right and left eyes can be seen the image through left vision district 5LJi right vision district 5R simultaneously, be to have occurred to crosstalk between the image data of left vision district 5LJi right vision district 5R, thereby affect the quality of spectators' viewing effect and image.
Therefore existing improvement method as shown in Figure 3, between the pre-corresponding pixel of image data prior to these two groups of different visual angles, with dyeing resin, metal material or its combination, increase the width of shading region BM between images of left and right eyes visual area, to reduce the situation of crosstalking; But above-mentioned improvement is crosstalked, the mode of situation can reduce the brightness of display when facing or not needing excessive vertical display view angle to watch, thereby must increase in advance the brightness of the backlight of display, and display rated disspation is increased.
Therefore, need a kind of crosstalk phenomenon reducing between vertical direction image, and in positive apparent time, do not affect the patterning phase retardation film of watching brightness, to improving the problems referred to above.
