Description
Technical field
The present invention relates to a kind of phasic difference film and the polarization type three-dimensional display that contains this phasic difference film.
Background technology
In recent years, along with the development of technology, 3D (three-dimensional) display is universal day by day, and all big enterprises all drop into huge fund in the stereo display field, launch cut-throat competition.At present, what family expenses 3D display technique adopted all is eyeglass stereoscopic display techniques, and the eyeglass stereoscopic display technique of main flow can be divided into fast gate-type (Shutter Glasses) and polarization type (Polarization 3D).
Fast gate-type 3D realizes 3D effect through the refreshing frequency that improves picture.When the 3D signal is input to display device; Through being divided into two image by frame; Form two group of pictures of corresponding left eye and right eye, staggered continuously showing, the synchronous signal transmitter is with the left and right sides eyeglass switch of synchronous 3D display and 3D glasses; Make images of left and right eyes see the images of left and right eyes picture respectively, pass through brain compound stereoscopic image again in the correct moment.The advantage of fast gate-type 3D display technique: the picture resolution is loss not, and full HD picture can be provided; Liquid crystal panel need not increase additional components, only needs to improve refreshing frequency, and cost is lower.The shortcoming of fast gate-type 3D: brightness is very low; Glasses need charging, and heaviness and price are high; Glasses have flicker; Picture is prone to crosstalks.
Polarization type 3D utilizes light to have the principle of " direction of vibration " to decompose original image; Earlier through being divided into image vertically to polarized light and level to polarized light two group of pictures; 3D glasses left and right sides eyeglass adopts the polarized lenses of different polarization direction respectively; People's right and left eyes just can receive two group of pictures respectively like this, passes through brain compound stereoscopic image again.
As shown in Figure 1, when carrying out 3D stereo display with linearly polarized light, it is two linear polarizer that the beholder wears glasses, its polarization direction should be orthogonal and also with display pannel before to add the polarization direction of polaroid consistent.For right left and right two pictures of the three-dimensional picture of formation that the beholder is seen are not crosstalked mutually; Except that the polarization direction that must make left eye and right eye two polaroids is mutually an angle of 90 degrees; About also requiring the beholder to keep as far as possible two sight line in same surface level (be not deflection of head, in the hope of with display pannel before to add the polarization direction of polaroid consistent).But watch in the process actual, this point often is difficult to long-time strict the maintenance.Therefore, because crosstalking each other between right left and right two pictures of three-dimensional picture, the beholder obtains the stereopsis effect and will inevitably incur loss.
In order to solve the above-mentioned defective of line polarization type, present polarization type display technique has generally adopted rotatory polarization, and its principle is as shown in Figure 2.Compare with fast gate-type, the advantage of polarization type 3D display technique is: the 3D Glasses structure is simple, need not power supply and wears lightly, and price is cheap; Behind the wearing spectacles, picture brightness is higher than fast gate-type; Though horizontal resolution reduces by half, owing to do not have shutter, so can not produce rocky sensation because of flicker.The maximum deficiency of polarization type is that its horizontal resolution reduces by half, and picture does not have fast gate-type careful.
Existing rotatory polarization formula 3D is that pattern phase retardation film (FPR, Film Pattern Retarder are called for short " phase retardation film ") is attached on LCD (LCD) panel (also claiming " liquid crystal panel "), and the structure of phasic difference film is as shown in Figure 3.If directly the phasic difference film is attached at (as shown in Figure 4) on the liquid crystal panel, when flexible phasic difference film and liquid crystal panel contraposition, need to increase the equipment of complex structure, cost is higher.
The attaching method of another kind of phase retardation film is the peel ply that removes earlier the phasic difference film; The bonding coat of phasic difference film is attached on the one side of transparent base; Fix with the another side and the contraposition of LCD panel of transparent base, the existing equipment of LCD capable of using like this factory carries out contraposition again.In order normally to observe the light from pixel, the height in phase delay zone is less than the height of pixel.Design feature because of existing phasic difference film; During attaching; Transparent base can be between liquid crystal panel and the phasic difference film (as shown in Figure 5), and this has just strengthened the contraposition difficulty and has influenced the visual angle: " visual angle " with the top that marks among Fig. 5 is example, if the right eye glasses get into the visual angle of left eye; Then can see, crosstalk from the light of left eye pixel.
