specific Embodiment approach 1

[0080] The manufacturing method of this embodiment comprises the following steps:

[0081] Step 1. Paste double-sided transparent tape on the LED unit board or apply a layer of transparent epoxy resin potting glue or use other types of transparent pasting materials.

[0082] Step 2. Attach a layer of protective film on the left and right circular polarizing strips to prevent the polarizing strips from being scratched or stuck to glue during the pasting process, thereby affecting the polarizing effect.

[0083] Step 3. Paste and fix the left and right circular polarizing strips alternately on the corresponding positions of the odd and even rows or columns of the LED unit board. The air bubbles are driven out.

[0084] Step 4. Peel off the protective film attached to the left and right polarizers.

[0085] Step 5. Paste a protective film or apply a layer of light-transmitting protective glue on the LED unit board on which the polarizing strip is fixed. The protective glue can ...

Embodiment approach

[0091] Such as Figure 9 , 10 As shown, the manufacturing method of the LED3D display module of the present invention includes: an LED display unit board 300, a plurality of left-handed and right-handed circular polarizing strips 310, 320, a driver IC50, a driver circuit board 53, an LED wafer 56, and a mask 55. The driver IC 50 is welded on the back of the driver circuit board 53 , the LED wafer 56 is fixed on the corresponding pixel position on the front of the driver circuit board 53 by SMT patches, and the mask 55 is fixed on the driver circuit board 53 and frames the LED wafer 56 . Wherein, the pixel pitch on the LED display unit board 300 is d=2mm, and the left and right circular polarizer strips 310 and 320 are respectively glued to the positions corresponding to the odd and even rows of the pixels of the LED display unit by epoxy resin. The width of the left and right circular polarizing strips 310, 320 should be greater than or equal to the width of the LED display p...

specific Embodiment approach 2

[0096] The manufacturing method of this embodiment comprises the following steps:

[0097] Step 1. Fix the mask on the LED unit board and the height of its upper surface should be between 0.1mm-1mm higher than the height of the upper surface of the LED display pixel

[0098] Step 2. Apply a layer of transparent epoxy resin potting glue or other types of transparent pasting materials on the LED unit board.

[0099] Step 3. Attach a layer of protective film on the polarizing module to prevent the polarizing module from being scratched or glued to glue during the pasting process, thereby affecting the polarizing effect.

[0100] Step 4. Paste and fix the polarizing module on the LED unit board, and the left and right polarizing strips on the polarizing module correspond to the rows or columns of the LED display pixels. Air bubbles between the display pixels are ejected on the plate.

[0101] Step 5. Peel off the protective film attached to the left and right polarizers.

Abstract

In allusion to the problems that a conventional chromatic aberration type display method exists a color cast phenomenon, a shutter type three-dimensional display method is high in cost, etc., the present invention provides a novel 3D display method in the LED field. An LED 3D display module and an LED 3D display system which are provided by the present invention enable the light to be changed from the original unpolarized light into the polarized light by utilizing the characteristic that the light possesses a vibration direction after the light passes a polariscope. If the polariscope is combined correspondingly to generate the polarized light of two different directions, and the two sets of generated polarized light is respectively mapped to a left eye and a right eye of an audience wearing a specially-produced glasses possessing the polarizing lenses, the audience can appreciate a 3D stereo image.

Description

technical field [0001] The invention belongs to the technical field of LED display, and in particular relates to an LED3D display module and an LED3D display system. Background technique [0002] In recent years, with the popularity of 3D images in the market, there are shutter 3D display methods and color difference 3D display methods in the field of LED 3D display. The chromatic aberration 3D display method is to display the graphic content on the plane by using complementary colors, and the viewer can watch the picture with both eyes at the same time by wearing an optical color filter, thereby synthesizing a 3D stereoscopic image in the brain. The 3D image effect is the worst, and there will be a phenomenon of color shift, so the real image color cannot be seen. The shutter-type 3D display method is to divide the image into two frames by increasing the screen refresh rate to form two groups of images that are continuously interlaced by the left and right eyes. 3D stereo...
