Abstract

A method for displaying a 3D image on an LCD monitor by inducing a circle polarized light from a linear polarized light is provided to employ optical activity materials having superior transparency according to lines, thereby obtaining a 3D image, which is relatively bright. Optical activity materials are arranged as matching a vertical or horizontal display line interval according to specific resolution of an LCD monitor so that the optical activity materials have opposite rotation axes. Polarized light is sequentially rotated according to the display lines by using a filter fabricated by coating a transparent adhesive solution on a glass substrate or a polyester transparent film so that a circle polarized light is induced. The polarized light is sequentially rotated in directions opposite to each other.

Method of implementing 3D image on LCD monitor by inducing circular polarization from linear polarization {Methode of the 3D display on a LCD monitor from conversion to circle polarized light from linear polarized light}

1-A through 1-A through a filter arranged in the form of 1-a-1 and 1-a-2 a material that delays linearly polarized light 90 degrees to the front of the LCD display device passing through the polarizing plate as shown in FIG. Polarization passing through a-1 and 1-a-2 becomes circularly polarized light rotating in opposite directions, respectively, and stereoscopic images can be obtained through glasses having corresponding circularly polarized light filters corresponding to opposite directions, such as 1-B. have.

The present invention utilizes the characteristics of a material that delays the phase of linearly polarized light of the light activating material by 90 degrees, rotates the linearly polarized light passing through the light activating material in the left or right direction, and induces circular polarization. To achieve the image.

The present invention belongs to the technical field for the stereoscopic image on the LCD monitor, and belongs to the glasses type of glasses-free and eyeglasses. In addition, among eyeglasses, there are electronic glasses using LCD shutters, color filter glasses using complementary colors, glasses using retardation filters, and glasses using polarizing glasses. The present invention belongs to the technical field using polarizing glasses. Among polarizing glasses, there is a method of using linear polarization and circular polarization, and the present invention is a method of implementing a stereoscopic image in the monitor using circular polarized glasses.

In the conventional method of realizing a stereoscopic image using linear polarization or circular polarization, linear polarization or circular polarization filters are arranged such that phases are orthogonal to each other, such as 2-a-1 and 2-a-2, as shown in FIG. The material placed on the front of the monitor and implemented through the corresponding polarized glasses and the material delayed by 90 degrees at equal intervals as shown in FIG. 3 are arranged in 3-a-1, and 3-a-2 is left empty. The polarized light that is bypassed to the compartment and the polarized light that is delayed by 90 degrees through 3-a-1 are orthogonal to each other and implemented through the corresponding linearly polarized glasses.

However, the method of orthogonally arranging the polarization filters of the conventional methods is difficult to manufacture because the polarization filters must be precisely cut and arranged and fixed in the case of high resolution monitors, and the brightness of the monitor is darkened by about 1/2 and the thickness of the filter is reduced. Due to the problems caused by the viewing angle has a very narrow disadvantage. Also, in this case, the polarization direction of the polarization filter applied to the LCD panel may vary according to the manufacturer of the LCD panel. Therefore, the manufactured filter cannot be applied to all LCD monitors. I have it.

In the conventional method described in FIG. 3, the phase delay filters are arranged one by one to correspond to the monitor display lines, so that the light having different filters and the brightness are different so that the image is received by the observer's left and right eyes. It has the disadvantage of feeling dizziness due to the difference in brightness and the diffraction of light due to the irregularities of the square and the square with the phase delay filter, which makes the image unclear. Similarly, the polarization direction of the polarization filter applied to the LCD panel may be different depending on the manufacturer of the LCD panel. Therefore, the manufactured filter cannot be applied to all LCD monitors because the polarization direction of the polarization filter applied to the LCD panel must be manufactured according to the polarization direction. I have it.

Therefore, the present invention was invented to overcome these disadvantages by using a photoactive material different from the conventional method.

The present invention delays the phase of linearly polarized light by 90 degrees, rotates the linearly polarized light in the left or right direction, and induces the circularly polarized light in the opposite direction to the horizontal or vertical display line spacing of the LCD monitor. It is arranged to have the rotation axis of and it is placed on the front of the LCD monitor, and the left and right images of the left and right images are alternately arranged for each display line of the monitor so that the stereoscopic images can be displayed through glasses equipped with circular polarization filters in opposite directions. It is a method invented to obtain. Through this method, the disadvantages of the conventional methods, such as brightness reduction, dizziness, and small viewing angle, are solved, and the effects of the invention are applicable to all of the filters of one method regardless of the manufacturer of the LCD panel.

1. As shown in FIG. 4, the phase of the linearly polarized light is delayed by 90 degrees and the passed linearly polarized light rotates in the left or right direction and changes to circularly polarized light in accordance with the specified resolution of the LCD monitor. Filters are manufactured by arranging them to have rotation axes in opposite directions in accordance with horizontal or vertical display line intervals, and applying the adhesive liquid having transparency to a glass plate or a polyester transparent film and fixing the same.

2. As shown in FIG. 5, the photoactivating material which delays the phase of linear polarization by 90 degrees and rotates the linearly polarized light in the left or right direction and changes it into circularly polarized light includes quartz horseshoe or sugar solution. Therefore, quartz horseshoe may be used for the present invention, and chemical mixtures having photoactivation characteristics such as sugar solution may be used when the solidified solution is dissolved in a solvent. The arrangement is applied to each display line so as to have rotation axes in opposite directions in accordance with horizontal or vertical display line intervals in accordance with the specified resolution of the LCD monitor, or the sliced minerals are alternated sequentially by display lines, and the rotation axes are opposite to each other. Arrange

3. Place the filter configured as described in 1 above on the LCD monitor front panel so that the horizontal line or vertical line coincides with the display line of the LCD monitor. At this time, the surface of the mineral applied or sliced with the light activating material is directed toward the LCD monitor panel. This is to prevent the narrowing of the viewing angle which may occur due to the thickness of the glass plate or the transparent polyester film to which the light activating material is fixed.

4. As shown in Fig. 1, since the polarized light passing through the filter of 1-A manufactured by the method of the present invention is displayed with circularly polarized light which rotates in opposite directions sequentially according to the order of the display lines, the direction of circularly polarized light is Observers wearing glasses such as 1-B are alternately arranged left and right for each display line on the monitor because each filter passes only circularly polarized light in the same direction as the circularly polarized light on which the filters are displayed. If binocular stereoscopic images are displayed, stereoscopic images can be observed.

According to the present invention, since the filter rotates linearly polarized light by circularly polarized light in a direction opposite to each other irrespective of the linearly polarized angle of the LCD panel, only one line filter is used regardless of the manufacturer of the LCD panel. When adjusted, they all have an applicable effect.

In addition, since the light activating materials arranged by line have better transparency than the conventional polarizing filter ice type, a brighter stereoscopic image can be obtained. Also, since all lines have the same transparency, dizziness caused by light brightness difference is eliminated. There is an effect that can be reduced. In addition, since the linearly polarized light is a three-dimensional image by circularly polarized light, even when the head is slightly moved, the viewing angle of view is superior to the linearly polarized light.
