Problems solved by technology

[0005] The present invention aims at the contradiction between the high lateral resolution requirements of the stereoscopic LED display technology and the difficulty in satisfying the high-resolution stereoscopic LED display requirements due to the limitation of the LED display screen manufacturing and heat dissipation process, as well as the glaring, moiré effect of traditional LED displays. Provide a new naked-eye 3D-LED display device due to shortcomings such as large stripes

Embodiment 1

[0041] In this embodiment, a naked-eye 3D-LED display device of the present invention is described by using a 2-viewpoint 3D-LED.

[0042] (1) Provide an LED display, each pixel in the LED display is arranged in a straight line and equidistant arrangement or a periodic non-linear but equal horizontal spacing, and the horizontal pixel pitch d1 is smaller than the vertical pixel pitch d2, d1, d2 Satisfy d2 / 30 image 3 As shown, each pixel on the LED display is composed of three sub-pixels of red (R) 11, green (G) 12, and blue (B) 13, which are arranged in strips, that is, the red, green, and blue sub-pixels are arranged vertically In the direction, the sub-pixels are uniformly spaced from top to bottom to form a vertical column, and in the horizontal direction, the sub-pixels of red, green and blue form a horizontal row, which are also arranged at uniform intervals, and the spacing between each sub-pixel is equal. Each sub-pixel is circular, and the horizontal pixel arrangement i...

Embodiment 2

[0053] In this embodiment, a 5-viewpoint 3D-LED is used to illustrate a resolution-compensated high-definition naked-eye 3D-LED display device of the present invention.

[0054] (1) Provide an LED display, each pixel in the LED display is arranged in a straight line and equidistant arrangement or a periodic non-linear but equal horizontal spacing, and the horizontal pixel pitch d1 is smaller than the vertical pixel pitch d2, d1, d2 Satisfy d2 / 30 Figure 4 As shown, each pixel on the LED display is composed of three sub-pixels of red (R) 11, green (G) 12, and blue (B) 13. The sub-pixels are rectangular in shape, and the horizontal width is smaller than the vertical length. way, that is, the red, green, and blue sub-pixels are arranged at uniform intervals from left to right in the horizontal direction to form a horizontal row, and in the vertical direction, the red, green, and blue sub-pixels each form a vertical column, and are also arranged at uniform intervals , the spacing b...

Embodiment 3

[0064] In this embodiment, a 5-viewpoint 3D-LED is used to illustrate a resolution-compensated high-definition naked-eye 3D-LED display device of the present invention.

[0065] (1) Provide an LED display, each pixel in the LED display is arranged in a straight line and equidistant arrangement or a periodic non-linear but equal horizontal spacing, and the horizontal pixel pitch d1 is smaller than the vertical pixel pitch d2, d1, d2 Satisfy d2 / 30 Figure 5 As shown, each pixel on the LED display is composed of three sub-pixels of red (R) 11, green (G) 12, and blue (B) 13. The shape of the sub-pixels is rectangular, and the horizontal width is smaller than the vertical length. together, separated by insulation. Preferably, in this embodiment, the sub-pixels of the LED screen have a horizontal width of 1.5 mm and a vertical length of 6 mm, so the horizontal pixel arrangement interval is 1.5 mm, and the vertical pixel arrangement interval is 6 mm. The number of horizontal pixels o...

Abstract

The invention discloses an LED naked eye 3D display device which comprises an LED display screen, a diffusion film and a parallax barrier raster, wherein the pixel density of the LED display screen in the longitudinal direction is different from that of the LED display screen in the transverse direction. The dot pitch of transverse pixels of the LED display screen is smaller than that of longitudinal pixels of the LED display screen, namely the transverse resolution is higher than the longitudinal resolution. The transverse high resolution is used for compensating for resolution loss of multi-view stereo display, and the stereo display longitudinal resolution is not lost, so that the longitudinal resolution is smaller than the transverse resolution, and cost is saved. The purpose that the dot pitch of the transverse pixels is smaller than that of the longitudinal pixels can be achieved through the shape or the arrangement of sub pixels. According to the LED naked eye 3D display device, on the premise that it is guaranteed that an existing LED display screen manufacturing process and an existing LED display screen heat dissipation process can meet the requirements of the pixel point density, the transverse resolution is improved through proper reduction of the longitudinal resolution, images are watched gently, and moire fringes are fewer.

Description

technical field [0001] The invention relates to an LED naked-eye 3D display device, which belongs to the field of free stereoscopic display. Background technique [0002] With the development of optoelectronic technology, LED display technology has been widely used. LED display is a high-tech product integrating optoelectronic technology, microelectronic technology, computer technology and video technology. ) is composed of splicing, which has the advantages of high brightness, environmental protection and energy saving, fast response, impact resistance and stable performance. LED display screens are widely used as displays, display boards, bulletin boards, etc. in occasions that require large size and high brightness. In addition, LED display technology can splice display units arbitrarily according to needs to form display screens of different sizes, resolutions and shapes. It has advantages that cannot be replaced by other display technologies in the fields of advertisin...
