背景技术Background technique
摩尔条纹(Moiré Pattern)是十八世纪法国研究人员摩尔先生首先发现的一种光学现象。从技术角度上讲，摩尔条纹是两条线或两个物体之间以恒定的角度和频率发生干涉的视觉结果，当人眼无法分辨这两条线或两个物体时，只能看到干涉的花纹，这种光学现象就是摩尔条纹。Moiré Pattern is an optical phenomenon first discovered by Mr. Moore, a French researcher in the eighteenth century. From a technical point of view, moiré fringes are the visual result of interference between two lines or objects at a constant angle and frequency. When the human eye cannot distinguish the two lines or two objects, it can only see the interference This optical phenomenon is called moiré fringes.
在裸眼3D显示中，由于光栅和显示面板都有各自恒定频率的条纹，所以有明显的摩尔条纹，已经成为困扰裸眼3D显示的重大困难。In the naked-eye 3D display, since the grating and the display panel have their own constant-frequency fringes, there are obvious moiré fringes, which have become a major difficulty for the naked-eye 3D display.

如图1和图2所示，本发明提供的一种显示装置，包括显示面板和光栅3，显示面板包括多个阵列分布的像素单元1，每一个像素单元1包括沿像素单元1行方向排列、且具有长方形结构的多个亚像素单元2，所述光栅3具有相互平行的多个挡光部31，每一个挡光部31沿与所述亚像素单元2的对角线平行的方向延伸；每一个所述亚像素单元2的长度方向与所述像素单元1行方向之间的夹角大于等于85度且小于等于95度，每一个亚像素单元2的尺寸满足下述公式：As shown in Figures 1 and 2, a display device provided by the present invention includes a display panel and a grating 3. The display panel includes a plurality of pixel units 1 distributed in an array, and each pixel unit 1 includes a pixel unit 1 arranged in a row direction. , and have a plurality of sub-pixel units 2 in a rectangular structure, the grating 3 has a plurality of light blocking parts 31 parallel to each other, and each light blocking part 31 extends along a direction parallel to the diagonal of the sub-pixel unit 2 ; The angle between the length direction of each sub-pixel unit 2 and the row direction of the pixel unit 1 is greater than or equal to 85 degrees and less than or equal to 95 degrees, and the size of each sub-pixel unit 2 satisfies the following formula:
a/b＝2/9；a/b=2/9;
其中：in:
a为每一个亚像素单元2的宽度；a is the width of each sub-pixel unit 2;
b为每一个亚像素单元2的长度。b is the length of each sub-pixel unit 2 .
上述显示装置中，每一个亚像素单元2的尺寸满足公式：a/b＝2/9，其中，a为每一个亚像素单元2的宽度；b为每一个亚像素单元2的长度。经过试验，发现当亚像素单元2的尺寸满足a/b＝2/9时，光栅3的每一个挡光部31沿着与亚像素单元2的对角线平行的方向分割像素时，裸眼3D显示产生的摩尔条纹是比较弱的，实际工作也证明了这一理论。In the above display device, the size of each sub-pixel unit 2 satisfies the formula: a/b=2/9, where a is the width of each sub-pixel unit 2 ; b is the length of each sub-pixel unit 2 . After testing, it is found that when the size of the sub-pixel unit 2 satisfies a/b=2/9, when each light blocking part 31 of the grating 3 divides the pixel along the direction parallel to the diagonal of the sub-pixel unit 2, the glasses-free 3D It shows that the generated moiré fringes are relatively weak, and the actual work also proves this theory.
因此，上述显示装置在裸眼3D显示中产生的摩尔条纹很弱。Therefore, the moiré fringes generated by the above-mentioned display device in naked-eye 3D display are very weak.
如图1所示，一种具体的实施例中，每一个亚像素单元2的长度方向与像素单元1的行方向垂直。As shown in FIG. 1 , in a specific embodiment, the length direction of each sub-pixel unit 2 is perpendicular to the row direction of the pixel unit 1 .

In a preferred embodiment, the three sub-pixel units 2 included in each pixel unit 1 are respectively a red sub-pixel unit, a green sub-pixel unit and a blue sub-pixel unit.
另一种具体的实施例中，如图3所示，每一个像素单元1的区域为正方形结构，沿像素单元1的行方向，每一行像素单元1包括多个像素单元对4，每一个像素单元对4包括两个像素单元1、且每一个像素单元对4的区域内可以包括九个亚像素单元2。In another specific embodiment, as shown in Figure 3, the area of each pixel unit 1 is a square structure, along the row direction of the pixel unit 1, each row of pixel units 1 includes a plurality of pixel unit pairs 4, each pixel The unit pair 4 includes two pixel units 1 , and each pixel unit pair 4 may include nine sub-pixel units 2 in the region.
由于每个像素单元1的区域为正方形结构，每个亚像素单元的尺寸为a/b＝2/9，所以当每一个像素单元对4的区域内包括九个亚像素单元2，即每两个像素单元1的区域内包括九个亚像素单元2时，亚像素单元2的排列可以非常紧密，可以减少黑矩阵在像素区域内所占的面积，进而提高显示面板的开口率。Since the area of each pixel unit 1 is a square structure, the size of each sub-pixel unit is a/b=2/9, so when each pixel unit pair 4 includes nine sub-pixel units 2, that is, every two When nine sub-pixel units 2 are included in the area of one pixel unit 1, the sub-pixel units 2 can be arranged very closely, which can reduce the area occupied by the black matrix in the pixel area, thereby increasing the aperture ratio of the display panel.
如图2所示，在上述各实施例的基础上，一种具体的实施例中，光栅3可以为狭缝光栅。As shown in FIG. 2 , on the basis of the above-mentioned embodiments, in a specific embodiment, the grating 3 may be a slit grating.

After testing, it is found that when the size of the sub-pixel unit 2 satisfies a/b=2/9, when each light blocking part 31 of the grating 3 divides the pixel along the direction parallel to the diagonal of the sub-pixel unit 2, the glasses-free 3D It shows that the generated moiré fringes are relatively weak, and the actual work also proves this theory.
因此，通过上述显示装置的制备方法制得的显示装置在裸眼3D显示中产生的摩尔条纹很弱。Therefore, the moiré fringes produced in the naked-eye 3D display of the display device prepared by the above method for preparing the display device are very weak.
