Description

TECHNICAL FIELD [0001] The present invention relates to a stereoscopic image display device and a method of driving the same,

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

The stereoscopic image display apparatus displays stereoscopic images by using the appearance of perspective when different image signals recognized by the two eyes are synthesized.

A stereoscopic technique, a volumetric technique, and a holographic technique are known as methods for implementing the stereoscopic image.

Of these, the binocular parallax system can be classified into a spectacular system and a non-eye system, and in recent years, no eye surgery has been actively studied.

* There is parallax barrier method and lensticularlens method which use parallax barriers again.

FIG. 1 is a view for explaining a method of implementing a stereoscopic image by a conventional non-eye-tightening stereoscopic image display apparatus, in particular, a stereoscopic image display apparatus using a lenticular lens system. FIG. 2 is a view showing an example of a viewing area of a conventional non-limiting type of three-dimensional image display apparatus. Particularly, FIG. 2 (a) (Multi-view) viewing area.

The 3D display device includes a parallax barrier or a sub-pixel lenticular lens as shown in FIG. 1 on a front surface of a panel 10 Sheet or the like, so that different images are sent to the left-eye and right-eye of a user to express a stereoscopic image.

In the parallax barrier system, a parallax barrier is used to selectively block light emitted from a panel of the stereoscopic image display device, thereby realizing a three-dimensional stereoscopic image by dividing the left eye image L and the right eye image R.

In addition, the lenticular lens system separates a left eye image and a right eye image by a lenticular lens 20 attached on a panel 10 of a stereoscopic image display device to realize a three-dimensional stereoscopic image.

That is, in the above-described non-eye-wear stereoscopic image display apparatus, the luminance distribution of the image seen by the viewer is different according to the position of the viewer, and the images are displayed on the left and right eyes, Thereby allowing stereoscopic images to be recognized.

In other words, the conventional non-eye-tightening stereoscopic image display apparatus uses a barrier (a lenticual, a parallax barrier, a switchable lens, a switchable lens, etc.) vertically arranged on a pixel of the panel 10, Dimensional stereoscopic image by separating the image based on the viewing distance.

2 shows a viewing area of a non-eye-tightening stereoscopic image display device using a lenticular lens 20 or a parallax barrier. In the case of (a) showing the viewing area of 2view, It can be seen that the size of the area 30 and the size of the area 40 are similar to each other and the regular area and the area are alternately generated. In the case of (b) showing the 3view view area, It can be seen that the regular time zone 50 is also increased by about 2 times as compared with the zone 60.

That is, in the stereoscopic image display apparatus, it can be seen that the size of the regular region increases when the number of contents and the number of views of the display apparatus are increased.

When the viewer moves forward or moves left or right beyond the above-mentioned time zone or area, the viewer is located in an unviewable area where both left and right images are mixed or both left and right images can not be viewed.

Since the viewable area can not be viewed by the viewer, the viewer can immediately recognize the viewable area. However, since the difference information of the image is also transmitted in the area, the viewer recognizes the image in three dimensions. It may not be immediately recognized that it is not a regular time zone.

Therefore, in this case, since the viewer can recognize that the eye fatigue or the like due to the viewing in the area is not the regular area, he feels the fatigue due to the stereoscopic viewing

In addition, when the viewer views the stereoscopic image display device for the first time in the stereoscopic image mode (3D mode) after turning on the stereoscopic image display device, the above-mentioned regular time zone can not be accurately grasped, There arises the inconvenience that it is necessary to change the position to the front, back, left and right.

In other words, the conventional stereoscopic image display apparatus can not notify the viewer of which area the viewer is located in the regular time zone, the area, and the unavailable area, and also can prevent the viewer from moving in any direction It does not provide information on whether it can be located in the time zone.

SUMMARY OF THE INVENTION The present invention is directed to a stereoscopic image display apparatus and a method of driving the stereoscopic image display apparatus which can guide a direction in which a viewer must move in order to be positioned in a time zone when a viewer is located in an area other than the regular time zone The technical problem is to provide.

A timing controller for generating an output control signal for causing the object to display information on a moving direction in which the object should be moved to be positioned in the time zone; And an output unit for displaying the moving direction according to the output control signal.

According to another aspect of the present invention, there is provided a method of driving a stereoscopic image display device, comprising: generating position coordinates of an object using an image collected through an image collection unit; Comparing the position coordinates with previously set viewing area data, and when the object is not positioned in the regular area of the viewing area of the non-eye-warming stereoscopic image, the moving direction to the regular area adjacent to the position coordinate is Generating an output control signal for causing the display to display; And displaying the moving direction according to the output control signal.

According to the above-mentioned solution, the present invention provides the following effects.

In other words, according to the present invention, when a viewer is located in an area other than the regular time zone, the viewer can change the position to an area suitable for viewing the stereoscopic image by guiding the direction in which the viewer must move in order to be located in the time zone Effect.

In addition, the present invention provides information on the viewing area in which the viewer is located, thereby enabling the viewer to view the stereoscopic image at a faster and more accurate position, thereby reducing fatigue of the viewer's eyes.

Next, the gate driver 130 includes one or more gate driver ICs to sequentially supply scan pulses (or gate pulses) to the gate lines G1 to Gn.

Next, the filter 140 separates the light irradiated from the panel into a left eye image and a right eye image, and outputs the separated image, thereby allowing the observer to recognize the stereoscopic image. As shown in FIG. 3, Respectively.

Here, as the filter 140, a lenticular lens or a parallel rack barriers may be applied. That is, as described above, the parallax barrier method using a parallax barrier and the lenticular lens method are used for the non-panoramic lens type.

That is, the output unit 160 includes a speaker, a lamp, and the like, and notifies the user of whether the current position of the viewer is a regular region of the viewing region through audio or light or a moving direction in which the user should move toward the regular region .

4 is an exemplary view showing an internal configuration of a timing controller of a stereoscopic image display apparatus according to the present invention.

As shown in FIG. 4, the timing controller according to the present invention includes a receiving unit 111 for receiving image data and various timing signals (DE, CLK, etc.) from a broadcasting system, A video data sorting unit 113 for rearranging and outputting the video data transmitted from the receiving unit according to the characteristics of the panel, a video data collecting unit 113 for collecting the video data collected through the video collecting unit 150, A position determination unit 114 for extracting position coordinates of a viewer who is viewing the stereoscopic image using the position determination unit 114, position coordinates of the viewer extracted through the position determination unit are compared with previously set viewing area data, Area, the area, and the unrecordable area, and then generates an output control signal for generating an output control signal corresponding thereto A generation unit 115 and a lookup table 116 for storing previously set viewing area data.

First, the receiving unit 111 receives the video data and the timing signal as described above, transmits the timing signal to the control signal generating unit 112, and transmits the video data to the video data arranging unit 113 do.

The control signal generation unit 112 generates control signals GCS and GCS for controlling the operation timings of the data driver 120 and the gate driver 130 using the timing signals transmitted from the receiver, DCS).

Next, the position determination unit 114 performs a function of extracting the position coordinates of the viewer who is watching the stereoscopic image display apparatus according to the present invention using the images collected through the image collection unit 150. [

Next, the output unit control signal generator 115 determines whether the position of the viewer is a time zone using the extracted position coordinates and the previously set viewing area data. As a result of the determination, when the position of the viewer is a regular region, an output control signal to be transmitted to the output section is generated so as to output a display indicating the regular region through the output section. As a result of the determination, if the position of the viewer is not the regular time zone, the output unit control signal generator extracts the closest time zone from the current user position using the viewing area data, . The output control signal generation unit generates an output control signal to be transmitted to the output unit in order to output the display indicating the moving direction through the output unit.

Fig.

That is, as described above, the viewing area can be divided into the regular area, the area, and the unviewable area. The area can be divided into three areas, namely, the arrangement positions of R, G, and B in the panel, When the above-described features are set, the above-described three viewing areas are also set to fixed position coordinates. Therefore, the manufacturer can set the viewing area of the corresponding stereoscopic image display device using the above- Information about the viewing area can be programmed and stored in the lookup table 116. [

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

FIG. 5 is a flowchart illustrating a method of driving a stereoscopic image display device according to an embodiment of the present invention. FIG. 6 is a diagram illustrating an example of a method of extracting a positional coordinate of a viewer from the stereoscopic image display device according to the present invention. Is an exemplary view illustrating a viewing area of the stereoscopic image display device according to the present invention. 8 is an exemplary diagram illustrating an external configuration of an output unit of the stereoscopic image display apparatus according to the present invention.

In order for a viewer to recognize an image output from the stereoscopic image display device as a stereoscopic image (3D), left and right images, i.e., images of two views must be formed on the left and right eyes respectively. In the case of the non-eye-hardened stereoscopic image display device, the stereoscopic image viewing area is limited by the optical path. In order to expand the viewing area, image contents composed of a plurality of views are required.

That is, as the number of views increases, the area where stereoscopic images can be viewed becomes wider. However, such a number of views is determined by the maker of the stereoscopic image display device, and can not be improved or changed by a viewer.

However, the viewing area is directly related to the viewer watching the stereoscopic image, and can be classified into the following three types.

The first viewing area is a time zone in which a viewer is suitable for viewing a stereoscopic image, and a left eye image is formed on the left eye of the viewer and a right eye image is formed on the right eye.

The second viewing area is a region where the viewer can feel a stereoscopic effect but can not see a normal stereoscopic image, and the right eye image is formed on the left eye of the viewer and the left eye image is formed on the right eye.

The third viewing area is a viewable area in which the viewer can not view the stereoscopic image and the left and right images are mixed and can not be seen or the image itself can not be viewed.

On the other hand, in order to view a stereoscopic image using the stereoscopic image display device, a viewer has to be located in a time zone in which the stereoscopic image is accurately realized.

However, it is not easy for a viewer to accurately find such a time zone. In other words, the viewer can not recognize the viewer-unreachable area because the viewer can not view it. However, since the difference information of the image is also transmitted in the case of the region, the viewer may not recognize the region immediately. In the case of the first viewing in the video mode, the above-mentioned position selection is wrong, and there is an inconvenience that the viewer has to change the position back and forth and right and left.

In order to solve the above-mentioned problems, a stereoscopic image display device according to the present invention is a stereoscopic image display device, in which a viewer can view a stereoscopic image through a part of a front surface of a case constituting the stereoscopic image display device according to the present invention, If the time zone is not the regular time zone, the moving direction to the closest time zone is displayed so that the viewer can know the area where the viewer is located, So that the viewer can voluntarily change the location.

That is, according to the present invention, in order that a viewer (user) watching a non-eye-wear stereoscopic image display apparatus can voluntarily find a regular region of a regular region, a region, and an unviewable region, The moving direction to the regular time zone is guided through the output unit 160 mounted on the case of the stereoscopic image display device, and the position (change) of the moving image to the area suitable for the viewer (user) And the like.

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

The first process is a process of generating position coordinates of a viewer (S102, S104). To this end, the present invention is a process for generating a position coordinate of a viewer by a position determination unit 114 .

In the second step, the position coordinates of the viewer (user) determined in the first step are compared with the viewing area data stored in the lookup table, and it is determined whether or not the position of the viewer is the position corresponding to the regular area (S106).

In the third step, an output control signal for controlling the output unit is generated using the information determined in the second process, and then the output control signal is transmitted to the output unit. The output unit determines whether the current position of the viewer is a time zone, (S108 to S114).

Hereinafter, the three processes of the present invention as described above will be described in detail with reference to FIGS. 5 to 9. FIG.

First, when the stereoscopic image display device is turned on to start outputting a stereoscopic image or when a two-dimensional (2D) image is output and the output mode is changed to a stereoscopic image (3D), the timing controller The image of the viewer is collected from the unit 150 (S102), and the position coordinates of the viewer are extracted (S104).

For example, when the infrared ray sensor is used as the image collecting unit 150, a plurality of infrared ray sensors may be disposed at the upper or lower end of the case that forms the appearance of the stereoscopic image display apparatus, depending on the angle of view. At this time, in the case of a non-eye-warming stereoscopic image display device, optical refraction may occur, so that it is not preferable that an infrared sensor is disposed on the back surface of the panel.

On the other hand, the coordinate system for determining the position of the viewer may be formed by the N by M coordinate system as shown in FIG. Here, the N by M coordinate system may be determined according to the resolution of the infrared sensor or the camera, and it is preferable that the N by M coordinate system is formed so that at least 10 view units can be distinguished from the view zone.

A specific method for the position determination unit 114 to determine the position coordinates of the viewer using the image collected through the image collection unit is as follows.

That is, the timing controller 114 of the timing controller scans the image capturing unit 150 from left to right or right to left of the stereoscopic image display apparatus, (W_person) (Y coordinate) of the object (viewer) can be found by analyzing the reflection time of the infrared ray and the distance information (D_person) (Y coordinate) of the object Can be obtained.

In particular, the position coordinates of the object (viewer)

That is, the coordinates (X, Y) of the object can be defined as {(W1 + W2) / 2, D_person}, where the origin of the X- Width), and the operation can be simplified by simplifying the X-coordinate of the object (viewer) to (W1 + W2) / 2.

In order to make the above determination, the image capturing unit 150 may be moved in the left or right direction or the up and down direction by a driving unit (not shown), and the position determination unit 114 may control the driving unit to control the position or angle of the image capturing unit, As described above, the image collecting unit can collect images through scanning.

When the camera is used as the image collection unit 150, the X coordinate may be determined by a face detection method or the like, and the Y coordinate may be determined by using disparity information of a stereo camera Or depth information of a depth camera.

That is, when the camera is used as the image collecting unit, the position determining unit can determine the X coordinate of the viewer by using a method of detecting the face of the viewer from the image collected through the camera. A method of detecting such a face can be applied to a method generally used at present, and a detailed description thereof will be omitted.

When a camera is used as an image collecting unit, a stereoscopic camera or a depth camera is applied to such a camera, so that the Y coordinate of the object (viewer) can be grasped by using the collected information.

Next, the output control signal generator 115 of the timing controller determines whether the area in which the current viewer is located corresponds to the current time area, using the coordinates of the viewer extracted in step S104 (S106 ).

As described above, the area in which 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, , The position of the viewing area also changes.

However, since the above values have already been determined at the time of manufacturing the stereoscopic image display device, the size and position of the viewing zone (diamond zone) are substantially fixed as shown in FIG. 7, (191) and the region (192) are alternately present.

Therefore, in the present invention, the diamond zone of the above-mentioned time zone or area is also converted into a database in a coordinate form and stored in the look-up table 116 in advance, It is possible to determine which area the current position of the viewer corresponds to.

That is, the output control signal generation unit 115 determines whether the position coordinates of the viewer determined by the position determination unit 114 correspond to which of the diamond zones stored in the lookup table, It is possible to determine whether or not the viewer position corresponds to the regular time zone.

The output control signal generating unit 115 generates the output control signal by using the position coordinates of the viewer transmitted from the position determining unit 114, the time zone stored in the lookup table, It can be determined whether or not the current position corresponds to the regular time zone.

Next, if it is determined that the user's position is a regular region, the output control signal generator generates an output control signal for indicating that the user is in the regular time zone, and outputs the output control signal to the output unit 160 , And the output unit 160 displays the time zone according to the output control signal (S114).

For example, FIG. 8 shows an output unit 160 composed of up, down, left, and right arrows. In this case, the output unit can indicate that the user is located in the current time zone by flicking all the arrows.

However, when the arrow is continuously blinked (On / Off), the output control signal generation unit 115 transmits the output control signal to the output unit only for a predetermined period of time because it may interfere with the user's viewing. Therefore, the output section blinks all the arrows as described above only for a predetermined time. In this case, the user recognizes that the user is in the time zone.

If it is determined that the user's position is not the current time region, the output control signal generator sequentially extracts the coordinates of the current time region near the current user position using the lookup table, And finally the time zone at the closest distance is extracted (S108). For example, as shown in FIG. 7, when the position of the user A is not the regular region, and the two regular regions 191 and 191 are output as a result of extracting the regular region adjacent to the user's location , The output control signal generation unit calculates the distances L1 and L2 by analyzing the coordinates of the center part of the two time zones and the position coordinates of the user and finally extracts the time zone at a closer distance.

Here, the time zone closest to the user's position is calculated in the following manner.

That is, the intersection coordinates when each corner is connected by a line segment in the regular time area (191 in FIG. 7) are obtained or stored in advance in the viewing area data of the panel. Since the regular area and the area are also displayed in an intersecting manner, a plurality of the coordinates may exist. In order to reduce the amount of distance calculation, the coordinates of the user's position are compared with the x-coordinate of the reference point coordinate of the current time zone to find the nearest time-zone reference coordinates to the left and right sides of the center of the user's position coordinates. Accordingly, a total of two reference points can be extracted, one for each of the left and the right based on the user's position, and the distance (L1, L2) from the user's position coordinate to the nearest time region (for example, L1 ). However, when a plurality of users are located in the same time zone at the same time, the user is guided based on a remaining position (e.g., L2) with a slightly distant user.

Next, the output unit control signal generator analyzes the coordinate of the finally extracted time-domain and the position coordinates of the user, and calculates a moving direction in which the user must move toward the time zone (S110).

When the direction to be moved is calculated through the above process, the output control signal generator generates an output control signal for indicating the movement direction to the output unit and transmits the output control signal to the output unit 160, In accordance with the output control signal (S112).

For example, FIG. 8 shows an output unit 160 composed of up, down, left, and right arrows. In this case, when the moving direction in which the user must move is the left side, the output unit allows the user to move to the corresponding position by turning on / off the left arrow as shown in FIG.

In the case of the regular time zone, the output unit is set to blink for a preset time, but when the direction of movement is indicated, the output unit can be continuously blinked until the user reaches the time zone.

Similarly, when the moving direction is the right side, the output unit allows the user to move to the corresponding position by turning on / off the right arrow, as shown in FIG.

While the present invention has been described above with reference to the exemplary embodiments of the present invention, the output unit 160 includes 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 whether a time zone is located or a direction in which a user should move to a time zone, and is a method of displaying a specific symbol or character on a display screen or outputting a voice by various methods such as a display method Can be constructed.

If there are two or more users who are not located in the regular time zone, an output window for confirming the user in which position the user matching the information currently outputted from the output unit can be confirmed is displayed on the output unit 160 May be further included.

For example, the output unit is provided with an LCD window or an LED window (hereinafter simply referred to as an 'output window') of a rectangular frame. After displaying the approximate position of the user through the output window, The right and left arrows can be used to display the regular time zone or the moving direction.

In this case, the LCD window or the LED window may represent the position between the stereoscopic image display device and the user in two dimensions (X, Y) or in one dimension (X). That is, since the regular region of the stereoscopic image display device is formed only in the left and right (X-axis) directions at a predetermined interval from the stereoscopic image display device as shown in FIG. 7, ) You can display only the approximate user location in the direction.

More specifically, for example, when the LCD window or the LED window is composed of three lamps arranged side by side, when the left lamp is turned on, the up-down and right-and-left arrows are used to set the time- If so, the information is for the user to the left of the stereoscopic image display device. Similarly, if the time zone or the moving direction is displayed in the state that the central lamp is turned on, the information is for the user at the center of the stereoscopic image display device. If the right side area or the moving direction is displayed in a state where the right lamp is turned on, This information is for the user on the right side of the stereoscopic image display device.
