Description
Technical field
The present invention relates to a kind of display device, particularly a kind of 3 d display device.
Background technology
At present, 3 d display device is mainly two kinds in order to the method showing stereopsis, it is a kind of for the wearing of beholder's palpus is through the glasses viewing display device of special processing, left eye or left eye different from image received by right eye and right-eye image is made alternately to produce stereopsis, the method just can see stereopsis because of the extra wears glasses of needs beholder, causes in use more inconvenient.
Another kind is the display device of bore hole formula, the method is the principle for display device utilization grating, the image making beholder not need any extra device of wearing that left eye and right eye can be allowed to see is different and produce stereopsis, is applied to the electronic three-dimensional display of printed matter, baseball card or part bore hole formula at present.Existing 3 d display device comprises a display panel and a column lens array.Display panel comprises multiple pixel, and column lens array and those pixels are oppositely arranged.Each pixel comprises one or three sub-pixels, those pixels are with fixed cycle arrangement, wherein the light that sends of those pixels is through column lens array to form an image capturing range, makes existing 3 d display device can produce the viewing area of more than two in specified distance.
When the left eye of beholder and right eye are respectively two different viewing areas, beholder just can watch stereopsis.But, because the periodic structure size of display panel and pel array is comparatively close, be easy to the light after making display panel outgoing and present uneven light line after via column lens array, beholder is caused easily to see the light and shade lines change of fixed intervals when watching stereopsis, and produce so-called repeatedly line effect (Moir é Effect), and then have a strong impact on the image display quality of 3 d display device.
Summary of the invention
The object of the present invention is to provide a kind of 3 d display device, use the problem solved existing for prior art.
The invention provides a kind of 3 d display device, comprise a pel array and a lens arra.Pel array comprises multiple sub-pixel, and lens arra comprises multiple lens pillars arranged in parallel.Each lens pillar comprises a central shaft, and each central shaft is skewed corresponding to a first direction and each central shaft and first direction accompany a pitch angle.Wherein, lens arra in order to receive and to launch the light that sub-pixel sends, and forms P viewpoint in a viewpoint end, P >=2 and P is integer.The sub-pixel forming each viewpoint corresponds to central shaft arrangement.
In one embodiment of this invention, each sub-pixel has a length and a width, and when the ratio of each length and each width is 3:1, each pitch angle is between 12.53 degree and 14.04 degree.
According to the 3 d display device disclosed by the present invention, because the sub-pixel forming each viewpoint corresponds to central shaft arrangement, make the arrangement of the sub-pixel disclosed by the present invention on first direction more irregular, therefore, 3 d display device can reduce repeatedly line effect, and the surrounding of stereopsis also reduces the jagged situation of appearance, and then improve the image display quality of 3 d display device.In addition, the corresponding arrangement mode of pel array and lens arra, the resolution that second direction can be made to reduce is distributed to first direction, and then the problem avoiding single direction resolution to reduce.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Accompanying drawing explanation
Fig. 1 is the embodiment schematic top plan view according to the 3 d display device disclosed by the present invention;
Fig. 2 is the close-up schematic view of the 3 d display device according to Fig. 1.
Wherein, accompanying drawing village
Embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate appended accompanying drawing to be described in detail below.
Please refer to Fig. 1 and Fig. 2, be respectively the close-up schematic view of the embodiment schematic top plan view according to the 3 d display device disclosed by the present invention and the 3 d display device according to Fig. 1.3 d display device comprises pel array 102 and lens arra 104.Pel array 102 comprises the Chang side Xing ﹚ in multiple sub-Xiang Su ﹙ and Fig. 1 and Fig. 2.In the present embodiment, pel array 102 can comprise 315 sub-pixels, each row can have 35 sub-pixels (namely along 35 sub-pixels of second direction S arrangement), every a line can have nine sub-pixels (namely along nine sub-pixels that first direction F arranges), first direction F is vertical mutually with second direction S-phase, but the present embodiment and be not used to limit the present invention.
Lens arra 104 comprises multiple lens pillars 60 arranged in parallel, and each lens pillar 60 comprises central shaft 62, and each central shaft 62 is skewed corresponding to first direction F and each central shaft 62 accompanies an inclined angle alpha with first direction F.Wherein, be a display unit 70 with the length side shape ﹚ in P sub-pixel ﹙ and Fig. 1 and Fig. 2, display unit 70 is along second direction S arrangement, and each lens pillar 60 equals the width W of P sub-pixel in the corresponding display unit 70(of the second direction S i.e. width of each lens pillar 60 on second direction S).Lens arra 104 in order to receive and to launch the light that sub-pixel sends, and forms P viewpoint in a viewpoint end, P >=2 and P is integer.In the present embodiment, be a display unit 70 with five sub-pixels, 3 d display device can form five altogether and look a ﹙ and P=5 ﹚, but the present embodiment and be not used to limit the present invention.
Wherein, the sub-pixel forming each viewpoint corresponds to central shaft 62 to arrange.In more detail, please refer to Fig. 2, in the present embodiment, the coding forming the sub-pixel of first viewpoint can be 1, the coding forming the sub-pixel of second viewpoint can be 2, the coding forming the sub-pixel of the 3rd viewpoint can be 3, the coding forming the sub-pixel of the 4th viewpoint can be 4, the coding forming the sub-pixel of the 5th viewpoint can be 5, wherein form the sub-Xiang Su ﹚ that namely the sub-Xiang Su ﹙ of first viewpoint be encoded to 1 to correspond to central shaft 62 to arrange, form the sub-Xiang Su ﹚ that namely the sub-Xiang Su ﹙ of second viewpoint be encoded to 2 to correspond to central shaft 62 to arrange, the sub-Xiang Su ﹚ that namely the sub-Xiang Su ﹙ forming the 3rd viewpoint is encoded to 3 corresponds to central shaft 62 to arrange, the sub-Xiang Su ﹚ that namely the sub-Xiang Su ﹙ forming the 4th viewpoint is encoded to 4 corresponds to central shaft 62 to arrange, the sub-Xiang Su ﹚ that namely the sub-Xiang Su ﹙ forming the 5th viewpoint is encoded to 5 corresponds to central shaft 62 to arrange.In other words, form the direction arrangement of the main centrally axle 62 of sub-pixel of first viewpoint, form the direction arrangement of the main centrally axle 62 of sub-pixel of second viewpoint, form the direction arrangement of the main centrally axle 62 of sub-pixel of the 3rd viewpoint, form the direction arrangement of the main centrally axle 62 of sub-pixel of the 4th viewpoint, form the direction arrangement of the main centrally axle 62 of sub-pixel of the 5th viewpoint, but the present embodiment be not used to limit the present invention.Should be noted, the arrangement be encoded on second direction S of sub-pixel is for carrying out periodic arrangement (in the present embodiment according to coding, be a unit of display 70 with five sub-pixels and arrange along second direction S), be different according to inclined angle alpha with the arrangement being encoded in first direction F of sub-pixel.
