Description
Technical field
The present invention relates to the 3 d display device technical field, relate in particular to a kind of 3 d display device that can realize freely changing and can in the two-dimensional observation plane, effectively optimizing between two dimension demonstration and the 3-D display observation visual angle, electrically-driven liquid crystal lens and 3 d display device thereof that specifically a kind of visual angle is optimized.
Background technology
3 d display device more and more is familiar with by popular now, and it mainly is to make the observer form stereoscopic vision by certain processing.So-called stereoscopic vision, promptly eyes are observed the sensation that things can be differentiated the far and near form of object, by right and left eyes is received different images respectively, perceive the stereovision and the depth of field of object after brain is overlapping, thereby experience the stereo perception of object.Therefore, 3 d display device need separate left eye and independently be received by people's left eye and right eye respectively with the right eye signal, thereby can allow the observer form the stereoeffect of object, finishes stereo display.
At present, the 3 d display device development roughly can be divided into eyeglass stereoscopic display device and autostereoscopic display apparatus so far.As its name suggests, thus the observer of eyeglass stereoscopic display device need wear the glasses of response kind of design obtains stereoscopic visual effect; The observer of autostereoscopic display apparatus then need not to wear any additional accessory, can obtain stereoscopic visual effect as normally watching before 3 d display device, because the convenience of bore hole formula observation is being studied discussion at present more and more.
The technical method of autostereoscopic display apparatus has multiple, comprises that lens arra, disparity barrier, the degree of depth merge, point to method such as backlight right and left eyes information is carried out apart.Lens arra formula 3 d display device is that lens arra is arranged between display panel and the observer, before generally being attached at display, mainly the light of transmission display device is carried out the change of the direction of propagation, thereby realize the separation of right and left eyes information based on the light refraction principle.Traditional lens arra adopts the transparent material of refractive index greater than air, by design lens-shape curved surface, before utilizing micro lens technology to form fixing optical element to place display, thereby realizes three-dimensional stereoscopic visual effect.Because this lens arra is the element of fixed optics face, so can't realize the 2D/3D translation function.Therefore, a kind ofly replace the electrically-driven liquid crystal lens of this fixed relationship element more and more to be much accounted of by electrically-driven liquid crystal, this liquid crystal lens not only can be realized the focusing lens array of equivalence, can also realize the conversion of 2D/3D.
Electrically-driven liquid crystal lens is made of last lower glass substrate, frame glue and the liquid crystal that is filled between glass substrate, liquid crystal and go up between lower glass substrate electrode drive is arranged respectively, accompanying drawing 1, accompanying drawing 2 examples the principle of work of electrically-driven liquid crystal lens.Principle of work synoptic diagram when accompanying drawing 1 is the demonstration of electrically-driven liquid crystal lens two dimension, this electrically-driven liquid crystal lens is made up of first substrate 11 that is oppositely arranged and second substrate 12, be respectively equipped with first electrode 13 and second electrode 14 on the opposite face of first substrate 11 and second substrate 12, be filled with liquid crystal layer 17 between first electrode 13 and second electrode 14, when not applying external voltage in the display plane or applying voltage when identical, liquid crystal in the liquid crystal layer 17 all keeps identical state, phasic difference through the liquid crystal lens stack is identical, light path is propagated and is not changed, and can realize that then two dimension shows; Principle of work synoptic diagram when accompanying drawing 2 is the demonstration of electrically-driven liquid crystal lens two dimension, its structure is identical with Fig. 1, in display plane, apply different voltage, changed the distribution of electric field, thereby make the liquid crystal in the liquid crystal layer 17 exist different states and form the effective refractive index variation that is similar to condenser lens, light through liquid crystal lens will be changed the direction of propagation according to the difference of refractive index, thereby can realize 3-D display.
The electrically-driven liquid crystal lens that adopts in the present 3 d display device can be realized the three-dimensional observation of many visual fields (multi-view), promptly can realize that by design electrode separation, variations in refractive index curve etc. many people multiple spot experiences the 3D vision effect simultaneously.But because the electrode in the existing electrically-driven liquid crystal lens generally is designed to the straight line strip, therefore this many people multiple spot only launches in the one dimension direction, and realization visual angle that can not be in full force and effect in whole two-dimensional observation plane is optimized.Electrode design in the existing electrically-driven liquid crystal lens as shown in Figure 3.
