Display Apparatus For Displaying Three Dimensional Picture And Driving Method For The Same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display apparatus, and more particularly, to a stereoscopic image display apparatus capable of displaying a stereoscopic image and a driving method thereof.

The stereoscopic image display apparatus displays a stereoscopic image by using perspective appearing when different image signals perceived by two eyes are synthesized.

As a method of implementing such a stereoscopic image, a binocular parallax technique, a volumetric technique, a holographic technique, and the like are known.

Among these, binocular parallax can be divided into glasses type and glassesless type, and recently, autonomous type has been actively studied.

The glasses-free type has a parallax barrier method and a lenticular lens method using a parallax barrier again.

1 is an exemplary view illustrating a conventional stereoscopic image display apparatus for implementing a stereoscopic image. In particular, a lenticular lens type stereoscopic image display apparatus is illustrated. In addition, Figure 2 is an exemplary view showing a viewing area of a conventional autostereoscopic 3D display device, in particular, (a) is an exemplary view showing a viewing area of a two view (2 view) method, (b) is a multi-view It is an exemplary view showing a viewing area of a (multi-view) system.

The 3D display device includes a parallax barrier or a lenticular lens in the form of a sub-pixel as shown in FIG. 1 on the front of the panel 10. By constructing a sheet or the like, a stereoscopic image is represented by sending different images to a left-eye and a right-eye of a user.

The parallax barrier method uses a parallax barrier to selectively block light emitted from a panel of a stereoscopic image display device, thereby realizing a three-dimensional stereoscopic image by dividing a left eye image (L) and a right eye image (R).

In addition, the lenticular lens method implements a 3D stereoscopic image by separating a left eye image and a right eye image with the lenticular lens 20 attached to the panel 10 of the stereoscopic image display apparatus.

That is, in the autostereoscopic 3D display device as described above, the luminance distribution of the image shown to the viewer is changed according to the position of the viewer, and the viewer uses the principle of displaying different images in the left and right eyes. Allow the user to recognize stereoscopic images.

In detail, a conventional autostereoscopic 3D display device uses a barrier (lenticualr, parallax barrier, switchable lens, switchable lens, etc.) disposed perpendicular to a pixel of the panel 10, and the left and right images. 3D stereoscopic image is realized by separating the image based on the viewing distance.

2 shows a viewing area of an autostereoscopic 3D display device using a lenticular lens 20 or a parallax barrier, and in the case of (a) showing a viewing area of 2 views, It can be seen that the size of the area 30 and the area 40 are almost similar, and the time zone and the area are alternately generated, and in case of (b) showing the viewing area of 3view, It can be seen that the time zone 50 is also about 2 times larger than that of the zone 60.

That is, in the stereoscopic image display apparatus, when the contents and the number of views of the display apparatus are increased, the size of the viewing area may be increased.

In addition, when the viewer moves forward or moves leftward or rightward than the regular region or the above-described region, the viewer is placed in an unviewable region in which left and right images are mixed or cannot view both left and right images. .

On the other hand, such an unviewable area cannot be viewed by the viewer itself, but can be immediately recognized by the viewer. However, in the case of the area, since the difference information of the image is transmitted, the viewer recognizes the image in three dimensions. It may happen that we do not immediately recognize that the location is not the time zone.

Therefore, in this case, the viewer can feel that the eye fatigue due to viewing in the area, but not the on-time area, so that the viewer feels tired from watching the 3D image.

In addition, when the viewer views the first time in the stereoscopic image mode (3D mode) after turning on the stereoscopic image display apparatus, the positional region as described above cannot be accurately identified, and thus the positioning is incorrect. Inconvenience to change the position back and forth and left and right occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and can be used to guide a viewer who is viewing an autostereoscopic 3D display device, which is located in a timed area, a still area or an unviewable area, and a 3D image display device and a driving method thereof.

Next, the image data alignment unit 113 rearranges the received image data according to the characteristics of the panel 100 and transmits the image data to the data driver.

Finally, the position determining unit 114 extracts the position coordinates of the viewer watching the stereoscopic image display apparatus according to the present invention by using the image collected through the image collecting unit 150, and outputs the output unit. The control signal generator 115 determines whether the viewer's position corresponds to the on-time region, the non-viewable region, or the non-viewable region by using the extracted position coordinates and the preset viewing region data.

That is, the viewing area of the stereoscopic image display apparatus according to the present invention may be divided into a regular area, a still area, and an unviewable area, as described above. If the above-described features are set, the three viewing zones as described above are also set to constant position coordinates, so that the manufacturer calculates using the above-described features. Information about the viewing area of the stereoscopic image display apparatus may be programmed and stored in the lookup table 116.

Hereinafter, a driving method of the stereoscopic image display apparatus according to the present invention having the configuration as described above will be described in detail with reference to FIGS. 5 to 9.

FIG. 5 is a flowchart illustrating a method of driving a stereoscopic image display apparatus according to the present invention. FIG. 6 is an exemplary diagram for explaining a method of extracting a viewer's position coordinates by the stereoscopic image display apparatus according to the present invention. Is an exemplary view showing a viewing area of a stereoscopic image display apparatus according to the present invention. 8 is an exemplary view showing the external configuration of the output unit of the stereoscopic image display apparatus according to the present invention, Figure 9 is an exemplary view showing the internal configuration of the output unit of the stereoscopic image display apparatus according to the present invention.

In order for a viewer to recognize an image output from a stereoscopic image display device as a stereoscopic image (3D), the left and right images, that is, two views, must be combined with the left and right eyes, respectively, using special stereoscopic glasses. In the case of the non-stereoscopic stereoscopic image display apparatus, an area for viewing a stereoscopic image is limited by an optical path, and image contents including a plurality of views are required to extend the viewing area.

That is, as the number of views increases, the area for viewing stereoscopic images becomes wider. However, the number of views is determined by the producer of the stereoscopic image display apparatus and may not be improved or changed by the viewer.

However, the viewing area is directly related to the viewer watching the 3D image, and may be classified into three types as follows.

The first viewing area is a position suitable for a viewer to watch a stereoscopic image, in which the left eye image is formed in the left eye of the viewer and the right eye image is formed in the right eye of the viewer.

The second viewing area is a position where the viewer can feel a three-dimensional feeling but cannot view a normal three-dimensional image, in which the right eye image is formed in the left eye of the viewer and the left eye image is formed in the right eye.

The third viewing area is a position where the viewer cannot watch a stereoscopic image, and the left and right images are mixed and the viewer cannot see the image or the image itself.

On the other hand, in order to watch a stereoscopic image using a stereoscopic image display apparatus, the viewer must be located in the time zone where the stereoscopic image is accurately implemented.

However, it is not easy for the viewer to find the correct time zone. That is, the viewer cannot recognize the non-viewable area immediately because the viewer cannot view it, but in the case of the area, the viewer may not immediately recognize the area because the difference information of the image is transmitted. When viewing the video mode for the first time, the position selection as described above is wrong, and there is a inconvenience that the viewer has to change the position back, front, left, and right.

However, the stereoscopic image display apparatus according to the present invention for solving the above problems, through any portion of the front surface of the case constituting the stereoscopic image display apparatus according to the present invention, the viewer to any region of the three areas; The purpose of the present invention is to indicate that the viewer is located in a certain area by indicating that the user is located so that the viewer can voluntarily change the location.

That is, according to the present invention, an output unit 160 mounted on a case of the stereoscopic image display apparatus may determine whether the viewer (user) who views the autostereoscopic 3D image display apparatus is located in the on-time region, the region, or the non-viewable region. ), And through this, a viewer (user) can change the location to a region suitable for viewing stereoscopic images.

To this end, the present invention can be divided into three processes as follows.

The first process is a process of generating the position coordinates of the viewer (S102, S104), for which the present invention is determined by the position determination unit 114 is the image collected through the image acquisition unit 150 composed of an infrared sensor or a camera, etc. Analyzing.

The second process compares the position coordinates of the viewer (user) determined in the first process with the viewing area data pre-stored in the lookup table. It is a process of determining whether it is a position corresponding to an area (S106).

The third process generates an output control signal for controlling the output unit by using the information determined in the second process, and then transmits it to the output unit so that the viewer's current position is in the on-time region, the still region, and the viewing region. This is a process of displaying which of the impossible areas.

Hereinafter, three processes of the present invention as described above are described in detail with reference to FIGS.

First, when the 3D image display device is turned on to start outputting a 3D image or when a 2D (2D) image is output and the output mode is changed to 3D (3D), the timing controller collects an image composed of an infrared sensor or a camera. The viewer 150 collects the video of the viewer (S102), and extracts the viewer's position coordinates (S104).

For example, when an infrared sensor is used as the image collecting unit 150, a plurality of infrared sensors may be disposed at the top or bottom of a case forming the exterior of the stereoscopic image display apparatus according to the angle of view. In this case, in the case of the autostereoscopic 3D display device, since optical refraction may occur, it is not preferable that the infrared sensor is disposed on the rear surface of the panel.

Meanwhile, as shown in FIG. 6, the coordinate system for determining the viewer's position may be formed by an N by M coordinate system. Here, the N by M coordinate system may be dominant according to the resolution of the infrared sensor or the camera, and may be formed to distinguish the viewing zone at least 10 units or more.

A detailed method of determining the position coordinates of the viewer by using the image collected by the image determining unit is as follows.

That is, the position determining unit 114 of the timing controller scans the image collecting unit 150 from the left to the right or the right to the left of the stereoscopic image display device, thereby displaying the stereoscopic image display as shown in FIG. 6. The width information (W_person) (X coordinate) of the object (viewer) in front of the device can be found, and the distance information (D_person) (Y coordinate) of the object (viewer) is analyzed by analyzing the reflection time of infrared rays. You can get it.

In particular, the position coordinate of the object (viewer) is

That is, the coordinate (X, Y) of the object may be defined as {(W1 + W2) / 2, D_person}, where the origin of the X-axis is shown in FIG. Width), and the X coordinate of the object (viewer) can be simplified by (W1 + W2) / 2.

For the above determination, the image collecting unit 150 may move left and right or up and down by a driving unit not shown, and the position determining unit 114 controls the driving unit to control the position or angle of the image collecting unit. As described above, the image collector may collect the image through scanning.

On the other hand, when the camera is used as the image acquisition unit 150, the X coordinate may be determined by a face detection method, etc., and the Y coordinate uses the difference information of the stereo camera. Or using depth information of a depth camera.

That is, when the camera is used as the image collecting unit, the position determining unit may determine the X coordinate of the viewer by using a method of detecting the viewer's face from the image collected by the camera. Since a method for detecting such a face may be applied at present, a detailed description thereof will be omitted.

In addition, when the camera is used as an image collecting unit, a stereo camera or a depth camera is applied to the camera, so that the Y coordinate of the object (viewer) can be grasped using the collected information.

Next, the output unit control signal generator 115 of the timing controller uses the position coordinates of the viewer extracted in step S104, so that the region where the current viewer is located is any region of the on-time region, the still region, or the non-viewable region. It is determined whether or not to correspond to (S106).

As described above, the area where the view zone is generated varies depending on the number of views, the size of the panel 100, the pitch of the pixels, the characteristics of the barrier 140, and the like. The position of the viewing area is also changed.

However, since the above values have already been determined at the time of manufacturing the stereoscopic image display apparatus, substantially the size and position of the viewing zone (diamond zone) are fixed as shown in FIG. 191 and the region 192 are alternately present.

Accordingly, in the present invention, the diamond zone of the time zone or the blank zone as described above is converted into a database in the form of coordinates and stored in the lookup table 116 in advance, while the output control signal generator generates the same. It may be used to determine which area the viewer's current location corresponds to.

That is, the output unit control signal generator 115 determines whether the position coordinates of the viewer determined by the position determination unit 114 correspond to which region of the diamond zone that is databased in the lookup table. It is possible to determine whether the viewer position corresponds to the on-time area or the still area.

On the other hand, the output control signal generator 115 compares the viewer's position coordinates and the database of the lookup table determined above, and as described above, whether the viewer's position is the on-time region or which of the still regions. It can be determined that the position of the viewer outside the coordinates of the on-time region and the region as described above can be seen that the non-viewable region.

That is, the output control signal generator generates the viewer's current position using the database of the viewer's position coordinates transmitted from the position determining unit 114 and the database of the on-time area and the blank area stored in the lookup table. Also, it can be determined whether or not it corresponds to one of the region and the non-viewable region.

Finally, the output unit control signal generator 115 generates an output control signal for controlling the output unit so that the information on the viewing area of the viewer determined through the above-described processes is output through the output unit. And the output unit 160 receiving the output control signal according to the output control signal, the viewing area corresponding to the current position of the viewer, that is, the on-time area, also the area, cannot be viewed according to the output control signal. One of the areas is displayed.

That is, the output unit 160 is configured in the form of a lamp having three different colors, as shown in Figure 8, according to the output control signal for outputting any one of the on-time region, still area, or non-viewable area By outputting the corresponding lamp, the viewer can check which area his location corresponds to.

To this end, the output unit 160 includes three lamps 161, 162 and 163 having three different colors as shown in FIG. 9, and an output control signal transmitted from the output control signal generator 115. FIG. It may be configured to include a switch 164 to select any one of the three lamps according to.

Meanwhile, in the above, the present invention has been described as the output unit 160 is configured using a lamp such as a light emitting diode (LED), but the present invention is not limited thereto.

Accordingly, the present invention is a method for notifying a viewer of the type of viewing area in which the viewer is located, and the output unit may be configured using various methods such as displaying a specific symbol or character on a display screen or displaying a voice. have.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
