Liquid crystal indicator is to utilize the variation that is clipped in electric field intensity on the liquid crystal molecule, and the power that changes the orientation control printing opacity of liquid crystal molecule is come display image, and an one pixel cell is made up of three RGB sub-pixels, and pixel cell is a square configuration.Because existing pixel cell is a square configuration, in Fig. 1, when the grating edge 13 of post lenticulation 12 forms a angle with the vertical normal direction of display panels 11, must causes 13 couples of single sub-pixel RGB of grating edge to form and cut apart.Thisly cut apart effect to cause seeing through the exit direction of light of single sub-pixel of grating edge 13 belows opposite, and the zigzag effect occurs at the image of grating edge 13.

The utility model content

Technical problem to be solved in the utility model provides a kind of liquid crystal indicator based on the post lenticulation, has solved grating edge and single sub-pixel has been cut apart the zigzag ill effect that causes.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of liquid crystal indicator, comprise a display panels, this display panels comprises a plurality of pixel cells that are rectangular distribution, and each pixel cell is made up of three RGB sub-pixels; One post lenticulation is attached to the outside of described display panels, and described post lenticulation is a with the angle of the vertical normal of described display panels, 0＜a＜90, and described post lenticulation comprises many post lens that are arranged in parallel; Wherein, described sub-pixel unit is the parallelogram shape and is arranged in order into many oblique lines, the left and right edges of every post lens respectively with the parallel coincidence in described sub-pixel unit edge, n sub-pixel unit of every complete in the horizontal direction covering of post lens, n is filled with black matrix more than or equal to 2 in the right-angle triangle zone of described display panels both sides.

Above-mentioned liquid crystal indicator, described pixel cell are equilateral parallelogram shape.

Above-mentioned liquid crystal indicator, the bond length of described sub-pixel unit are 0.1mm, and long edge lengths is 0.3mm.

The utility model contrast prior art has following beneficial effect: the liquid crystal indicator that the utility model provides, described sub-pixel unit is the parallelogram shape and is a with the angle of the vertical normal of display panels all with described post lenticulation, make n sub-pixel unit of every complete in the horizontal direction covering of post lens, avoid grating edge that single sub-pixel is cut apart the zigzag ill effect that causes, thereby realize better 3 D stereo display effect.
