Background technology
Double vision shows, namely utilizes a display screen, makes different beholders see two different pictures.Double vision is presented in actual life and has wide practical use.Such as, in some families, only having a TV, same time adult wants to see TV play, and child wants to watch animated films.The common method that addresses this problem in reality is that the subregion shows multiple different picture (picture-in-picture function) in display device, but under this mode, picture can be reduced, affects display effect, is not obviously a kind of perfect scheme.
In recent years, along with the fast development of 3D technology, double vision display technique and the display device that is similar to 3D display technique principle appearred utilizing.Its ultimate principle is similar with the 3D displaying principle of present main flow, is divided into active-shutter, polarization type, bore hole formula.
The principle that the active-shutter double vision shows is: the shutter liquid crystal glasses opens and closes at a high speed respectively, controls different beholder's perception unlike signals, and the televisor cooperation refreshes to provide at a high speed two width pictures.This double vision display mode needs the refresh rate of televisor to reach original twice, thereby supports different beholders' two width Picture switchs to show.
The polarization type double vision shows, utilize glasses and TV itself jointly to cooperate to produce two width images different from the shutter double vision, polarization type double vision device mainly relies on the polarizing coating of liquid crystal panel front end, the picture that TV is shown is divided into angled polarized light, and the beholder is by wearing the polarising glass different parallax picture of perception respectively.At present industry denounces for the maximum of polarization type and is the loss of resolution, displaying principle due to polarized light, the image resolution that this mode forms can only reach half of former film source, " accurate high definition " level of the actual 540p of only having after namely the full HD signal of 1080p shows by polarization type.
The bore hole technology mainly contains the methods such as parallax barrier, lens pillar makes the people who is in diverse location see different pictures.But the bore hole technology is still immature, and output is also unstable, and price is high.
Traditional polarization type double vision shows as shown in Figure 1, it is the different pictures of two width that the odd-numbered line of LCD display and even number line (or odd column, even column) are divided into what present, put a polarization separation layer thereon, this layer effect is that odd-numbered line is adjusted into the corresponding polarization directions of different beholders (two polarization directions are mutually vertical) with the polarization direction that the even number line pixel shows.Therefore after synthesizing, when watching by polarising glass, the beholder who wears different polarization direction glasses can only receive strange, the even number line image that meets own polarization direction.Therefore, the image resolution ratio of the picture that the whichever beholder is observed only has 1/2nd of former LCD display, and this is also the greatest drawback that the polarization type double vision display device exists.
Summary of the invention
The utility model is for the proposition of above problem, and develop a kind of polarization type double vision display device of novelty, these application of installation polaroid glasses, consisted of by AMOLED display layer, TFT key-course, liquid crystal polarized layer and front glass, dynamically control the liquid crystal deflection direction of each pixel in liquid crystal polarized layer by the TFT key-course, obtain the different polarization image of two width after decomposition, different observers is by wearing the orthogonal polarising glass in polarization direction, the picture that can obtain to wish.The technological means that the utility model adopts is as follows:
A kind of high resolving power is not dodged the formula double vision display device, comprises framework and display part; Described display part is made of display layer, TFT key-course, liquid crystal polarized layer and front glass successively.
The selection AMOLED display layer of described display layer optimum.
Described display layer is the LCD display layer.
This high resolving power is not dodged the formula double vision display device can not sacrifice the resolution of former display device, in conjunction with the combination of AMOLED display screen and liquid crystal can have that resolution is high, transmitance is high, the advantage such as low of crosstalking.In addition, because it is simple in structure, not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.

Embodiment
Illustrate by reference to the accompanying drawings embodiment:
Specific embodiment is referring to Fig. 2, and this high resolving power is not dodged the formula double vision display device, comprises framework and display part; Described display part is made of display layer 1, TFT key-course 2, liquid crystal polarized layer 3 and front glass 4 stacks successively.The selection AMOLED display layer of described display layer optimum.Described display layer also can be the LCD display layer.
before the explanation principle of work, at first we illustrate the first and second two beholders (more beholder in conjunction with Fig. 3, as long as wear corresponding glasses) image that obtains by polaroid glasses, as shown in Fig. 3 (c), the first and second two width images (polarization direction is vertical) according to certain pixel on display, can determine that the pixel before decomposition shows intensity, and image is (being assumed to be 45 degree directions) determined by the polarization direction after the AMOLED display layer, as shown in Fig. 3 (a), like this on the AMOLED display layer, we can be by the demonstration of above-mentioned synthetic each pixel, determine the demonstration image on the AMOLED display layer, each pixel will deflect into the α direction according to synthetic polarization direction afterwards, as shown in Fig. 3 (b).By the decomposition of polaroid, just obtained respectively first, the second image of corresponding polarization direction at last.
Below we illustrate the effect of each several part by this case device again, as shown in Figure 2, the AMOLED display layer shows is composograph before the first and second two width picture breakdowns, the polarization direction is 45 fixing degree directions (also can be other directions), and this can realize easily by add corresponding polarizing coating on the AMOLED display layer.Clip liquid crystal polarized layer between front glass and TFT key-course, this effect of three layers is the polarization direction of dynamically controlling each pixel.The effect of TFT key-course is the voltage of controlling each pixel, make liquid crystal deflect under Control of Voltage, the effect that liquid crystal deflects is to make the polarization of light direction by this point change, so on polarization layer, the yawing moment of each pixel namely is adjustable to needed α direction.After the adjustment of polarization direction, can be just the image of two vertical direction polarizations and being obtained by the first and second two beholders that wear different inclined to one side eyes respectively with picture breakdown, so just can realize the double vision demonstration.Because each pixel on the AMOLED display layer can be decomposed the eyes that enter each beholder, therefore the resolution of picture can not reduce by half, and adopt the AMOLED display device to belong to autoluminescence, front only need to add a polarizing coating, so transmitance is far above the double vision display device with the traditional LC D of principle.Traditional polarization type double vision shows between the odd-numbered line that also has the polarization separation layer and even number line, and cross-interference issue can occur, and is that the full frame pixel is dynamically controlled in the principle due to this patent, does not have this problem, thus have advantages of crosstalk low.
