Description

TECHNICAL FIELD [0001] The present invention relates to a stereoscopic display device,

The present invention relates to a non-eyeglass stereoscopic image display apparatus, and more particularly to a non-stereoscopic image display apparatus for a plurality of viewers capable of simultaneously viewing different types of 3D images, 2D images, 3D images, and 2D images according to preferences of a plurality of viewers will be.

A stereoscopic image display device for displaying a stereoscopic image in three dimensions (3D) so as to have a rich sense of reality has been applied to various fields such as medicine, education, game, movie, and television. The stereoscopic image display device allows the viewer to recognize the stereoscopic effect by the left and right parallax images by separating the left eye image and the right eye image spatially or temporally.

As a method of displaying a 3D image, there are a glasses type using a special type of glasses, and a non-type type using no special type of glasses.

The three-dimensional display device of the eyeglass type displays a 3D image by displaying the polarized direction of the left eye image and the right eye image on the display panel in a manner that is separated or displayed in a time-division manner and separating the left and right images using polarized glasses or liquid crystal shutter glasses. do. The spectacle stereoscopic display device provides a satisfactory stereoscopic effect regardless of the viewing position, but there is an inconvenience that the viewer must wear special glasses.

The stereoscopic display apparatus of the non-eyeglass system can be applied to a 3D optical system such as a Parallax Barrier, a Lenticular Lense, a Switchable Barrier or a Switchable Lense installed in front of or behind a display panel The 3D image is provided to the viewer by spatially separating the left and right images through the filter. The non-eyeglass stereoscopic display device has been developed continuously because it has an advantage that a viewer can view the 3D image without glasses although the viewing area in which the viewer can view the 3D image is limited.

In the viewing area implemented by the non-eyeglasses stereoscopic display device, the left eye image and the right eye image are input to the left and right eyes of the viewer, respectively, so that a stereoscopic viewing area in which a viewer can view a normal 3D image, There is a reverse stereoscopic area in which the left eye image is input to the viewer and the viewer views the abnormal 3D image. The non-eyeglass stereoscopic display apparatus uses a multi-view image and a multi-view map structure to widen the stereoscopic viewing area. The multi-view image is an image generated by capturing an object by separating the camera from the camera by the distance between the viewers, and the number of views is determined by the number of cameras that photograph the object. For example, a multi-view image of an object using four cameras has four views.

In general, the spectacles stereoscopic display apparatus can view only one kind of 3D image or only one kind of 2D image regardless of the number of viewers.

For example, as shown in Fig. 1, in the 2D mode, the first and second viewers P1 and P2 watch one kind of 2D image displayed on the non-optical stereoscopic display device 10 regardless of the viewer position . In the 3D mode, the first and second viewers P1 and P2 having different positions at specific viewing distances view one type of 3D image displayed on the spectacle-free stereoscopic display device 10. [

In the 3D mode, the left eye and right eye images are displayed on a pixel-by-pixel basis in accordance with a view map of the display device. Pixels are divided and displayed for each subpixel.

Accordingly, the conventional non-eyeglass stereoscopic display device has a problem that all viewers must view the same image in the same 2D mode or 3D mode regardless of the preference of a plurality of viewers. Accordingly, it is necessary to implement different types of 3D images, 2D images, 3D images, and 2D images according to the preferences of a plurality of viewers.

In the stereoscopic display apparatus, a phenomenon in which a right eye image enters the left eye or an image overlaps the left eye image in the right eye is defined as a 3D crosstalk. For a plurality of viewers, a different 3D image, 2D image, It is necessary to reduce 3D crosstalk among viewers in order to improve image quality when 3D images and 2D images are simultaneously implemented.

The non-eyeglass stereoscopic image display apparatus shown in Fig. 2 includes a display panel 20 for displaying an image, a 3D optical filter 30 disposed at a position of at least one of a front surface and a back surface of the display panel 20, A timing controller 24 for controlling the driving timing of the panel driving unit 22, and a display controller 24 for selectively driving the single or plural kinds of input image data in accordance with the view map, And a formatter 40 for rendering the image data by mapping and outputting it to the timing controller 24. The non-eyeglass stereoscopic image display apparatus further includes a viewer detection unit 50 and a position determination unit 52 for detecting the viewer position and providing the viewer area information of the viewer to the formatter 40.

The display panel 20 simultaneously displays a plurality of types of 3D images, 2D images, 3D images, and 2D images according to a viewer's viewing mode, or displays a single 3D image or 2D image. To this end, the display panel 20 displays a multi-view image through a multi-view structure in which a plurality of views are sequentially and repeatedly arranged in units of pixels or surf pixels. The view structure may have a vertical line structure, a horizontal line structure, or a Slanted line structure, and the view structure may be different depending on the characteristics and purpose of the display panel 20. [ The display panel 20 displays n multi-view images through n (n is an integer of 2 or more) views. The n views are spatially segmented to display multiple types of 3D and / or 2D images for a plurality of viewers, or to display a single 3D or 2D image. In order to clearly distinguish the viewing area for each viewer when displaying a plurality of types of 3D and / or 2D images on the display panel 20, a black view is inserted between adjacent views displaying different types of images among the n views do.

As the display panel 20, a liquid crystal panel, an organic light emitting diode display panel, a plasma display panel, or the like can be used.

In the case where the display panel 20 is a liquid crystal panel, for example, the display panel 20 includes a color filter substrate on which a color filter array is formed, a thin film transistor substrate on which a thin film transistor array is formed, And a polarizing plate attached to the outer surfaces of the color filter substrate and the thin film transistor substrate, respectively, and a backlight unit (not shown) for supplying light to the back of the display panel 20 is further provided. The display panel 20 displays an image through a plurality of pixels arranged in a matrix form. Each pixel implements a desired color by a combination of red / green / blue (R / G / B) sub-pixels that adjust the light transmittance by varying the liquid crystal array according to the data signal, As shown in FIG. Each sub-pixel has a thin film transistor connected to a gate line and a data line, a liquid crystal capacitor connected in parallel with the thin film transistor, and a storage capacitor. The liquid crystal capacitor charges the difference voltage between the data signal supplied to the pixel electrode through the thin film transistor and the common voltage supplied to the common electrode, and drives the liquid crystal according to the charged voltage to adjust the light transmittance. The storage capacitor stably maintains the voltage charged in the liquid crystal capacitor. The liquid crystal layer is driven by a vertical electric field such as a TN (Twisted Nematic) mode or VA (Vertical Alignment) mode, or by a horizontal electric field such as an IPS (In-Plane Switching) mode or an FFS (Fringe Field Switching) mode.

The 3D optical filter 30 is attached to at least one of the front surface and the back surface of the display panel 20 to spatially separate images displayed on the display panel 20 and disperse the images by viewing areas. The 3D optical filter 30 includes a parallax barrier in which a barrier for blocking light and a slit for transmitting light are alternately arranged, a lenticular lens having a lens array structure for dispersing light, a liquid crystal A switchable barrier capable of driving a barrier region and a slit region and varying a position of a barrier region and a slit region according to a position of a viewer or a liquid crystal or the like is driven to form a lens, A switchable lens that can vary the position of the lens according to the position of the viewer is used.

The 3D optical filter 30 spatially separates n view images displayed on the display panel 20 and outputs them to n viewing zones. When a plurality of viewers are located at intervals of at least one viewing zone in the n viewing zones, each of the plurality of viewers is displayed in a corresponding view area of the display panel 20 in a corresponding viewing area formed over at least two adjacent viewing zones It is possible to view different kinds of 3D and / or 2D images displayed. Of course, a plurality of viewers can view the same 3D or 2D image.

The panel driver 22 for driving the display panel 20 includes a data driver (not shown) for driving the data line of the display panel 20 under the control of the timing controller 24, And a gate driver (not shown) for driving the gate line of the panel 20. The gate driver sequentially drives the gate lines of the display panel 20 using a plurality of gate control signals from the timing controller 24. [ The data driver converts the video data from the timing controller 24 into an analog signal and supplies the video data to the data lines of the display panel 20 using a plurality of data control signals from the timing controller 24. [

The timing controller 24 aligns the image data from the formatter 40 according to the characteristics of the display panel 20 and supplies the image data to the data driver. The timing controller 24 generates a gate control signal and a data control signal using a plurality of input synchronization signals from the formatter 40, and supplies the gate control signal to the gate driver and the data control signal to the data driver.

The formatter 40 renders the image data by selectively mapping a plurality of or a single type of image data input from the outside in accordance with a view mode input from the outside to a pixel or a sub pixel in accordance with the view map of the display panel 20 And outputs it to the timing controller 24. The viewing mode signal is selected by the viewer and input to the formatter 40 through the external computer system.

The formatter (40) includes a formatter (40) that, when the viewer vehicle is in the viewing mode for viewing the plurality of types of 3D images or 2D images, or viewing a plurality of types of 3D images and 2D images, Divides the image data into a plurality of view groups, maps the corresponding 3D or 2D image data to each of the divided view groups, and outputs the result.

The formatter 40 includes a mode determination unit 42 for determining a viewing mode by inputting a viewing mode signal input from the outside, a data rendering unit 42 for rendering the image data according to the viewing mode determined by the mode determination unit 42 44).

The data rendering unit 44 maps the plurality of kinds of 3D or / and 2D image data to pixels or subpixels of the corresponding view among the n multiviews of the display panel 20 according to the judgment viewing mode from the mode determination unit 42 Or outputs the same 2D image data as it is, or outputs the same 2D image data as it is.

For example, when a plurality of viewers want to view two kinds of 3D images, the data rendering unit 44 displays the n views corresponding to the display panel 20 as the first and second views including at least two views Dividing the 3D image data into at least two views included in the first group, and mapping the 3D image data to at least two views included in the second group, Map separately by view.

In addition, when displaying a plurality of types of 3D and / or 2D images, the data rendering unit 44 may divide the viewing area into a plurality of views, Inserts a black view, maps black data to a black view, and outputs the black data.

In the viewing mode for displaying the 3D data, the data rendering unit 44 may shift or mix the view images according to the position information of the viewers input through the viewer detection unit 50 and the position determination unit 52, So that it can always be positioned in the stereoscopic viewing area.

The viewer detecting unit 50 photographs a viewer using a camera or an infrared sensor or transmits the recognized image to the position determining unit 52. [

The position determination unit 52 extracts the position coordinates of the viewer from the image supplied from the viewer detection unit 50, and calculates coordinates of the viewing area stored in advance in the form of a lookup-table (LUT) And compares with the viewing zone coordinates to determine the viewing zone in which each viewer is located. Also, the position determination unit 52 determines whether each viewer is located in the stereoscopic viewing area or in the inverse stereoscopic viewing area according to the viewing zone in which each viewer is located.

The data rendering unit 44 maps the 3D or 2D image that each viewer wants to view to at least two views corresponding to the viewing zone information of each viewer supplied from the position determination unit 52 and outputs the map.

When it is determined from the viewing zone information of each viewer supplied from the position determination unit 52 that the viewer is in the backward stereoscopic area, the data rendering unit 44 shifts the view image corresponding to the viewing zone information of the viewer So that the viewer can view the 3D image in the stereoscopic viewing area.

For example, when one viewer is located in the sixth viewing zone and the first viewing zone among the six viewing zones corresponding to the six view images, the viewer is positioned in the inverse stereoscopic region and the abnormal 3D image is displayed So that the viewer can additionally insert any one of the shift seeker and the first to fifth views by one pixel (or sub-pixel) to the right of the six view images, so that the viewer can see the fifth viewing zone and the sixth viewing zone It is located in the stereoscopic viewing region where the left eye and the right eye are respectively located, and the normal 3D image is viewed.

As described above, the spectacles stereoscopic display apparatus for a plurality of viewers according to the present invention can display a plurality of kinds of 3D images, 2D images, or 3D images and 2D images for a plurality of viewers at the same time through space division (i.e., view division) have.

Hereinafter, only the non-eyeglass stereoscopic display device according to the present invention will be described with reference to two types of images and two viewers, but the present invention can be applied to two or more types of images and two or more viewers.

3, the viewer mode signal indicates a viewing mode in which two viewers can simultaneously view two types of 3D images. When two types of 3D image data are input from the outside, the formatter 40 performs data rendering And maps two kinds of 3D image data to pixels or subpixels of the corresponding view in accordance with the view map of the display panel 20 through the input /

4A to 4C are views showing a view rendering structure for a display panel according to an embodiment of the present invention.

Referring to FIG. 4A, in a spectacle-free three-dimensional display device having a slantive six view characteristic, the display panel 10 has a structure in which six views are sequentially repeated in units of pixels or subpixels.

Assuming that the first viewer is located in the first and second viewing zones and the second viewer is located in the fourth and fifth viewing zones, the image that the first viewer perceives for one frame is displayed as shown in FIG. 4B An image that is displayed on the first and second views of the panel and an image that the second viewer perceives during one frame is an image displayed on the fourth and fifth views of the display panel as shown in FIG.

Therefore, the first viewer positioned in the first and second viewing zones can display the first and second views displayed on the first and second views by the parallax of the left and right eye images respectively displayed on the first and second views of the display panel 20 And the second viewer located in the fourth and fifth viewing zones can see one kind of 3D image by the parallax of the left and right eye images respectively displayed on the fourth and fifth views of the display panel 20, And the 3D image of the second type displayed in the fifth view.

FIGS. 5A and 5B are views illustrating a view structure for a 3D image and a 2D image in a display panel according to an embodiment of the present invention. FIG. 6 is a diagram illustrating a 3D or 2D image For example.

5B, when only one of the left eye and right eye images is selected and displayed at the first and second view positions of the display panel 20, the first viewer can display the first and second views The 2D image is viewed.

In the case of the second viewer, other kinds of 3D or 2D images displayed at the fourth and fifth view positions of the display panel 20 can be viewed in the same manner as the first viewer. At this time, since the view recognized by each viewer is the same, resolution reduction does not occur.

Accordingly, as shown in FIG. 6, the first and second viewers P1 and P2 can independently select and view an image, and can also select 3D and 2D to view.

Therefore, it is possible to provide a plurality of viewing modes that a plurality of viewers can view in the spectacle-free stereoscopic display apparatus of the present invention. For example, the non-eyeglass stereoscopic display apparatus of the present invention can be applied to a first viewing mode in which a plurality of viewers can simultaneously view a plurality of types of 3D images, a second viewing mode in which the same 3D images can be viewed, A fourth viewing mode in which the same 2D image can be viewed or a fifth viewing mode in which a plurality of types of 2D and 3D images can be viewed can be provided. The viewer can simultaneously display a plurality of types of 3D images, 2D images, 3D images, and 2D images, or simultaneously view the same 3D or 2D images by selecting one of a plurality of viewing modes provided by the non-eyeglass stereoscopic display apparatus.

In the case of a stereoscopic display apparatus, a phenomenon in which a right eye image enters the left eye or a left eye image appears in the right eye overlaps the image is defined as a 3D crosstalk. 3D crosstalk in a spectacle- It is a very important factor.

The non-eyeglass stereoscopic display apparatus according to the present invention is required to provide an independent image for each viewer, so that the importance of the 3D crosstalk is very high. The non-eyeglass stereoscopic display apparatus according to the present invention uses a black view insertion (BVI) method to reduce the 3D crosstalk and easily distinguish the viewing position for each viewer.
