Description
Technical field
The present invention relates to a kind of liquid crystal device of realizing 3-D display, relate in particular to a kind of switch liquid crystal panel of realizing the display device that two dimension and 3-D display pattern can be switched.
Background technology
Two eyes of people are observed the angle difference of things owing to separate certain distance, thereby the image that same object forms in people's left eye and right eye has nuance, i.e. so-called " parallax " usually.Brain is handled according to two different images, forms the degree of depth and three-dimensional sensation, produces 3-D view, as Fig. 1.Realize that by two-dimensional picture the principle of work of the display device of stereo display is for wanting stereoscopic images displayed to generate two images, and by special optical design, left eye is only seen supplied with the image (left image) that left eye is seen, right eye is only seen the image (right image) that the supply right eye is seen.Image is limited send to left eye or right eye that the mode of multiple realization is arranged.Very directly two width of cloth different images supply left eye and right eye are got final product for head mounted display.Other display mode need be done optical design, the light transmission path of control specific image.Utilize the transmission direction of grating control light, perhaps utilize double-colored glasses, can realize that left eye and right eye see different images.Need bespectacled display mode to be commonly called stereo display (StereoScopic), do not need bespectacled 3-D display implementation to be commonly called automatic stereo and show (Auto-StereoScopic).
Sharp Corp (Sharp Corporation) proposed a kind of two liquid crystal displays (LCD Panel) that utilize and realized that the switchable display packing of two-dimentional 3-D display was [referring to Adrian Jacobs, et al.2D/3DSwitchable Displays, Sharp Technical Journal No.4, April 2003].Increase a switch liquid crystal panel in common demonstration liquid crystal panel front, on the switch liquid crystal panel, form the electrode pattern of answering with grating pair, can gauge tap faceplate part light transmission part light tight, play the grating effect, the observer can see 3-D view.When the whole printing opacity of switch liquid crystal panel, display system is with two-dimensional model work, with common two-dimentional display effect much at one.This 3-D display mode has reduced the utilization ratio of light because a part of light is covered, and under the 3-D display pattern, the transmitance of light obviously descends.And this display device is restricted to best viewing areas, defines observer's viewing area.
United States Patent (USP) 7227568B2 and Chinese patent 200580010287.5 provide a kind of double polarizing light light filter, cooperate display device can realize the three-dimensional switchable LCD stereoscopic display spare of two dimension.Be operated under the 3-D display pattern, the observer need wear polaroid glasses.According to the realization thinking of this patent, showing the one side of liquid crystal panel, add and put a switch liquid crystal panel towards the observer, come optionally to showing that the light that liquid crystal panel sends changes the polarization direction.The light of backlight becomes the polarized light that has color and monochrome information after showing liquid crystal panel.Under normal two dimensional mode, show that liquid crystal panel normally shows, picture element signal is not done the differentiation of left eye and right eye signal, the switch liquid crystal panel is not made polarization direction to the light of all demonstration liquid crystal panel pixel outgoing with perhaps making any distinction between and is changed not changing its polarization direction from the light that shows liquid crystal panel incident.Because human eye can not be distinguished polarisation, what the observer saw is exactly the light that shows that each pixel of liquid crystal panel is sent, with there not being the switch liquid crystal panel the same.Under the 3-D display pattern, show that the pixel of liquid crystal panel is divided into two classes, show left image and right image respectively.The switch liquid crystal panel applies electric signal and makes the polarisation of light direction generation an angle of 90 degrees deflection of one of left image and right image in the corresponding region of corresponding this two classes pixel.Like this, the demonstration liquid crystal panel shows the emergent light of left image and right image after through the switch liquid crystal panel, will propagate with the form of the orthogonal polarized light of direction.The polarization direction of the left and right sides eyeglass of polaroid glasses is parallel respectively with two polarization directions of light of above-mentioned propagation, and like this, what observer's left eye and right eye were seen is respectively left image and right image, handles through brain, forms the sensation of stereo-picture, as shown in Figure 2.
United States Patent (USP) 7227568B2 and Chinese patent 200580010287.5 provide a kind of double polarizing light light filter, realize that optionally polarization direction changes.The double polarizing light light filter has two opposing substrates to constitute, and forms transparent public electrode on one of them substrate, has on the another one substrate to be formed with a plurality of transparency electrodes, implements control by the electric conductor that has comprised other conductor layers and thin film transistor (TFT).The voltage signal that applies on the transparency electrode has determined whether light filter changes the polarization of incident light direction.
Above-mentioned implementation method is the higher manufacture method of a kind of cost, is embodied in the film growth and the repeatedly graphical technology that need the multilayer conductive layer, also needs the film growth and the image conversion technology of insulation course.
Above-mentioned implementation method is the higher manufacture method of a kind of cost, and the manufacturing that also is embodied in thin film transistor (TFT) is a kind of very complicated semiconductor technology, to the equipment of making, produce clean environment, starting material and chemical treatment medicine, and technological parameter control requirement is very harsh, technological process is loaded down with trivial details.
Above-mentioned implementation method is except that manufacturing cost is higher, and yield rate also is restricted.There is certain yield rate restriction in this technology that is embodied in thin film transistor (TFT).More multi-layered conductive layer connects and may be short-circuited or open circuit, and also is a factor that reduces yield rate.
On substrate, form a plurality of transparency electrodes that can independently control, need make signal for driving circuit with another layer conductive layer and connect.Have stray capacitance on the conductive layer line, under the situation that keeps a plurality of transparency electrodes, for reducing signal lag, electrode need connect with the metal conducting layer of low-resistivity.Therefore must need the other conductive layer of one deck low resistivity at least except that transparency electrode.In addition, also need between above-mentioned two conductive layers, form insulation course, and remove insulation course in place, come and couple together in the position of needs so that two conductive layers is isolated electric.Like this, if form a plurality of discrete transparency electrodes on substrate, the space that this light filter manufacturing cost reduces is limited.
