Description

3D PANEL DEVICE OF FLUIDIC LENS WITH VARIABLE FOCAL LENGTH USING ELECTROWETTING}

The present invention relates to a three-dimensional image panel device using the convergence and diffusion of light by a microlens having an electrically adjustable refractive index by implementing a microfluidic lens array using an electron wetting phenomenon. Using a microlens that is electrically adjustable to the same size as the unit pixel of, the condensed and convex lenses simultaneously form the condensed and convex lenses of the light emitted from each pixel to represent a three-dimensional image. In the case of a three-dimensional image using a variable-focus microfluidic lens array characterized in that the light is diffused to adjust the refractive index of the light emitted through each pixel to provide a perspective according to the image corresponding to the main view of the real person It is about the implementation panel.

Currently, the 3D display uses a polarized or shutter-type special glasses to recognize the 3D image by having a left and right image having a certain depth according to the position of the image formed on both eyes of the user.

However, in the case of using special glasses, it is easy to cause dizziness and eye fatigue. Therefore, in order to solve the inconvenience of wearing special glasses, and to realize more three-dimensional and lively three-dimensional images, three-dimensional images without special glasses are used. Korea is actively developing.

 According to the stereoscopic image formation method, it is classified into stereoscopic stereoscopic method using two left and right two-dimensional images, volumetric display technology, and holographic display technology using object scattering information. In detail, stereoscopic image display technology using special glasses, multi-view stereoscopic display technology using a special optical system, integrated image display technology providing a viewing angle rather than a viewpoint using a lens array, and continuous cross-sectional image of an object. Volumetric stereoscopic display technology to reproduce, and holographic technology to reproduce the wavefront of the three-dimensional object.

Three-dimensional display methods that do not use special glasses include parallax barriers and lenticular screens.

Most of the above techniques use binocular parallax, which gives different observation differences in the left and right eyes, so that the simultaneous visual difference between the two eyes induces the illusion that objects form a three-dimensional effect. This method uses a lenticular lens, a specially manufactured red blue glasses, or polarized glasses.

However, the binocular disparity method can cause extreme fatigue of the eyes and is not marketable to those who can't close one eye or make a difference between both eyes. There is a problem in not recognizing the three-dimensional effect, the application environment and the field is very narrow. Also, it is difficult to consider the marketability by wearing glasses because it is inconvenient. In the case of Parallax or Integral, the applicability is high due to the relatively high production cost and complexity. Uneasy.

Accordingly, there is a need for a 3D display technology capable of selectively implementing 2D and 3D images without being affected by the position and movement of both eyes of the user. That is, the next-generation stereoscopic image display technology, as well as the problem of cost, should secure a wider viewing angle than in an autostereoscopic system, and of course, to solve the problems described above to form a three-dimensional effect even if both eyes are not secured, Dynamic changes in images that change in real time should be considered to involve fast motion.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an original image using an electrowetting phenomenon as compared to a 3D image implementer wearing polarized glasses using a conventional binocular parallax principle. An object of the present invention is to provide a 3D realization panel that enables a user to view a 3D image by a variable focusable fluid lens that diffuses or converges light emitted from each pixel based on perspective information.

In order to achieve the problem to be solved by the present invention,

According to an embodiment of the present invention, a three-dimensional image implementing panel device including a variable focusable microfluidic lens array using an electrowetting phenomenon is provided.

According to the present invention including the above-described configuration, the following effects can be obtained.

The 3D implementation panel using a variable focusing microfluidic lens array can form lenses in various stages using the free curvature of the lens according to the change in the magnitude of the constant voltage.

In addition, when the above voltage is not applied, the microlens formed in each pixel operates like non-refractive glass, so that it is possible to form a 2D display and easily convert 2D to 3D.

In addition, the microlens is not only easy to form a structure, but also a hardware program, compared to the existing technology for realizing many stereoscopic images, and can be directly controlled in the field of mobile phones, video media, and 3D games. Because it can be a big advantage in application.

ELECTROWETTING, which causes the charged aqueous solution to move by applying an electrostatic force to the charged aqueous solution using an electrode separated by a hydrophobic insulating film, has recently been used to represent an image by colored oil in the electronic paper field. This is used for the purpose of realizing each pixel, but has not been implemented for the purpose of realizing the perspective by refracting the light of each pixel from the display as described above.

As described above, the principle of converging or diverging the light emitted from each pixel by using the ELECTROWETTING phenomenon is applied to the principle of seeing an object by an actual human eye. As the distance between the eyes and the eyes increases, the angle of reflection decreases, and as the distance increases, the angle of the reflected light becomes larger, and by focusing and recognizing the angle of incidence of the reflected light reflected by such a person through the lens, To determine the distance. In addition, the human eye recognizes only one viewpoint (PRIMARY SIGHT) at a time, and other images are visible but are out of focus but cannot recognize an accurate image. And through the process of focusing another to recognize this image can see the image with perspective.

The 3D realization panel using the variable focusable microfluidic lens array makes a variety of different focal points on one screen by using the principle of focusing on such a person's objects, and the gaze point that a person currently sees among the images displayed on the screen. It is a new dimension of 3D image panel that makes it possible to distinguish the perspective with only one eye, by clearly displaying only the image in {PRIMARY SIGHT} and the other surrounding images with different focus.

In addition, as the material of the conductive liquid 105, saline solution, various fluids having good fluidity and a transparent electrolyte are used. The transparent fluid oil 104 is a transparent hydrophobic oil having a refractive index different from that of the conductive liquid 105. Clear flowing oils can be used.
