Description

Glasses-free 3D display method and device capable of simultaneous 2D/3D output {Method and device for glasses-free 3D display capable of simultaneous 2D/3D output}

The present invention relates to a three-dimensional display, and more particularly, to a glasses-free three-dimensional display device and method capable of simultaneous two-dimensional and three-dimensional output.

In response to the 5G era, there is a demand for ‘three-dimensional/multi-view’ content that utilizes large-capacity videos/images. In order to be able to see a 3D stereoscopic image, 3D display technology is a technology that requires the viewer to wear special glasses such as shutters or polarized glasses, so-called stereoscopic display technology, and a technology that does not require the use of glasses , the so-called auto-stereoscopic display technology. Glasses-free display technology has the advantage of being able to display a 3D image without the inconvenience of wearing such glasses. Glasses-free display devices capable of stereoscopic expression are generally classified into a parallax barrier type 3D display device and a lenticular 3D display device.

A lenticular lens is a three-dimensional picture embedded in a bookshelf or character sneaker that has been frequently seen since childhood in a glasses-free 3D method, and refers to a small vertical lens with an uneven surface. This lens separates the image from left to right and is called a vertical lenticular sheet.

In addition, the parallax barrier is an optical element constructed by alternately arranging vertical slits that transmit and block light, and means a vertical slit arrangement. This is a method of separately observing the left-eye image and the right-eye image by viewing the display panel through a vertical slit arrangement so that the observer's left and right eyes look at different pixels on the panel.

The parallax barrier has a simple structure and is relatively easy to switch between 2D and 3D, so it is widely applied to glasses-free 3D displays. However, since most of the light emitted from the panel is blocked, there is a problem in that the brightness of the 3D image is lowered. A device placed in front of an image source, such as a liquid crystal display, to allow a viewer to present stereoscopic or multifunctional images without the need to wear 3D glasses.

Both the Parallax Barrier method and the Lenticular method have the disadvantage of distorting the output image of the existing display by using a film on the existing display. In particular, in the case of the lenticular method, image distortion due to the physical lens array occurs severely, and this occurs more severely as the area per lens for securing multiple views increases. This distortion phenomenon is more severe due to the application of a technique for slantingly arranging a lenticular array in order to reduce crosstalk and utilize multiple views in sub-pixel units. That is, when outputting an image/image that is not rendered properly on a lenticular sheet, the initially intended image/image is not output due to the inclined lenticular array, which outputs a relatively precise object such as text. Doing so will further reduce readability/visibility.

1 is an enlarged perspective view of a part of a lenticular device that is converted from a 2D display to a 3D display by applying a voltage in a conventional 2D/3D glasses-free display device. Referring to FIG. 1 , a lenticular device or lenticular lens sheet 50 includes a transparent glass or plastic substrate 52 that can be about 7 mm thick. Transparent electrodes such as indium zinc oxide (IZO) and indium tin oxide (ITO), which may have a thickness of about 550 Å, are formed on the substrate 52 , that is, first electrodes 54 and 56 . The electrodes 54 and 56, that is, the first electrode, have stripe shapes extending parallel to the column direction to determine the lens period or pitch of the lenses, as will be described later. An insulating layer 58 having a thickness of about 500 to 600 Å is formed on the surfaces of the electrodes 54 and 56 and the exposed substrate. The insulating layer 58 may be a silicon oxide film SiOx or a silicon nitride film SiNx. A material layer 60 that can be changed into a lens shape by application of a potential in the thickness direction is disposed on the insulating layer 58 . Such a material can be a material selected from field-activated electro-active polymers (field-activated EAPs), which are lightweight, high piezoelectric modulus, mechanical properties, good flexibility and high strength It is required to have the properties of A second electrode or a common electrode 62 is formed on the material layer 60 . For the second electrode 62, a material having properties of high optical transparency, high strength, high flexibility or stretchability, and low resistance is required. The electrodes 56 may be wired to be connected at the top or bottom, and the electrodes 54 may be wired to be connected at opposite ends to the wiring of the electrodes 56 . The electrodes 54 and 56 may be graphene layers instead of IZO or ITO, and in the case of the use of a graphene layer, the overall thickness may be reduced by the use of a graphene layer thinner than the thickness of the IZO or ITO layer, , the overall flexibility can be improved. That is, the lenticular device for a two-dimensional/three-dimensional glasses-free display as shown in FIG. 1 includes a material layer deformable in the thickness direction with respect to the application of a voltage or potential between the electrodes, and when a voltage is applied, it transforms into a lenticular cylinder shape to form a 2D/ A transition between 3D takes place.

As described above, the conventional 2D/3D variable display utilizes a variable optical device using a liquid crystal under a lenticular sheet, and requires an additional optical device to implement a three-dimensional display.

And the conventional 2D/3D variable display is realized by using a material that is deformable in the thickness direction by application of voltage or potential between transparent and stretchable electrodes. This requires an additional electric device to implement a three-dimensional display, and it was impossible to apply only a part of the display during 2D/3D conversion depending on the technology method. 2D/3D variable display manufacturing difficulty increases and manufacturing cost is high, and there is a limitation in that it is difficult to apply to various display panels.
