The present invention relates to a stereoscopic image display apparatus, and more particularly, to a stereoscopic image display apparatus capable of viewing a stereoscopic image using a pattern leader system or a shutter glasses system in accordance with a user's selection.

The stereoscopic display is divided into a stereoscopic technique and an autostereoscopic technique.

The binocular parallax method uses parallax images of left and right eyes with large stereoscopic effects, and is divided into a glasses system and a non-glasses system. In the spectacle method, the polarizing direction of the left and right eye images is changed by a space-division or time-division method to a direct view type display panel or a projector, and stereoscopic images are implemented using polarizing glasses or shutter glasses. In the non-eyeglass system, stereoscopic images are realized by separating the optical axes of left and right parallax images using optical plates such as switchable barriers, parallax barrier, and lenticular lenses.

The patterned retarder (PR) system, which displays the left and right eye images in a space division manner and implements a stereoscopic image using polarized glasses, has the advantage of less crosstalk and less eye fatigue. In addition, the shutter glasses (SG) system that displays left and right eye images in a time-division manner and realizes stereoscopic images using shutter glasses has an advantage in that a stereoscopic image can be realized at a full resolution.

In the case of the products currently on the market, it is determined by either the Pattern Drifter method or the shutter glasses method, and is sold.

The 3D formatter may include a control unit for controlling the two-dimensional image data and the shutter glasses, and a formatter unit for multiplying a frame of the two-dimensional image data output from the control unit.

And a shutter glasses control signal transmitter for transmitting a control signal to the shutter glasses corresponding to the time-division three-dimensional image data from the 3D formatter.

The time division mode in which the left eye image and the right eye image are time-divisionally is a mode in which left eye image data is written on the display panel during the odd frame period and the left eye shutter of the shutter eyeglasses is opened, And the right eye shutter of the shutter glasses can be opened.

And a polarizing glass including a left eye polarizing filter having the same optical absorption axis as the first pattern drier and a right eye polarizing filter having the same optical absorption axis as the second pattern drier.

Wherein the spatial division mode for dividing the left eye image and the right eye image by a space divides the left eye image data and the right eye image data of the polarizing glasses during the same frame in which the left eye image data is written in the odd- The left eye image and the right eye image can be respectively transmitted to the filter.

The shutter glasses control signal transmission unit 140 transmits the shutter glasses control signal C _ST input from the 3D formatter 170 to the shutter glasses control signal receiving unit 130 via the wire / do. The shutter glasses control signal receiving unit 130 is installed in the shutter glasses 30 and receives the shutter control signal C _ST through the wired / wireless interface. The shutter glasses control signal receiving unit 130 receives the shutter control signal C _ST , It opens and closes the shutter (ST _L) and the right eye shutter (ST _R) alternately.

The user can select a time division mode in which the left eye image and the right eye image are time-divided through the user switching unit 160 and a space division mode in which space division is performed. The user switching unit 160 includes a touch screen, an on screen display (OSD), a keyboard, a mouse, a remote controller, or the like, which is attached or built on the display panel 10.

The 3D formatter 170 converts the RGB data input from the host system 180 into three-dimensional image data.

2, the 3D formatter 170 includes a control unit 171, an formatter unit 172, and a memory 174. [ RGB data (RGB) is input from the host system 180 to the control unit 171. [ The control unit 171 determines whether the input RGB data (RGB) is a two-dimensional image or a three-dimensional image by receiving the two-dimensional / three-dimensional mode signal. When the RGB data (RGB) of the two-dimensional image is inputted, the control unit 171 outputs the RGB data (RGB) to the formatter unit 172 without conversion. The control unit 171 receives the time division mode / space division mode signal from the user switching unit 160 and outputs the time division mode / space division mode signal to the formatter unit 172.

Further, the control unit 171 generates a shutter glasses control signal (C _ST ) for controlling the shutter glasses. The control unit 171 outputs the shutter glasses control signal C _ST to the shutter glasses control signal transmission unit 140. The shutter glasses control signal C _ST is transmitted to the shutter glasses control signal receiving unit 130 to alternately open and close the left eye shutter ST _L and the right eye shutter ST _R of the shutter glasses 30.

In the case where the user selects the time division mode, that is, the shutter glasses method, the RGB data (RGB) of the three-dimensional image input from the control unit 171 includes both the left eye image and the right eye image in one frame. Upon receiving the time division mode signal transmitted from the control unit 171, the formatter unit 172 separates the RGB data (RGB) into the left eye image and the right eye image when the RGB data of the three-dimensional image is input. Here, when the RGB data is a full HD image of 1920 x 1080, the formatter unit 172 has two, and each of the formatter units 172 multiplies the image of 960 x 1080.

The formatter unit 172 doubles or quadruples the frame of the RGB data. First, when RGB data of a 60-Hz two-dimensional image is input, three frame images predicted by the MEMC (Motion Estimation / Motion Compensation) are inserted and the frequency is multiplied by 4 times. Therefore, RGB data of a two-dimensional image having a frame frequency of 60 Hz is multiplied by a frame frequency of 240 Hz. MEMC is a technique for improving motion picture response time (MPRT), and is a technique for inserting an image to be predicted between frame data.

The formatting unit 172 receives the spatial division mode signal transmitted from the control unit 171. When the RGB data of the three-dimensional image is input, the formatter unit 172 receives the spatial division mode signal, The left eye image is arranged on the odd number lines of data (RGB) and the right eye image is arranged on the even line. Here, when the RGB data is a full HD image of 1920 x 1080, the formatter unit 172 has two, and each of the formatter units 172 multiplies the image of 960 x 1080. Then, the formatter unit 172 multiplies the RGB data of the two-dimensional image having the frame frequency of 60 Hz at a frame frequency of 240 Hz as in the above-described time division mode.

The RGB data of the three-dimensional image output from the formatter 172 is input to the timing controller 150 and stored in the memory 154. [ The RGB data of the two-dimensional image output from the formatter 172 is also input to the timing controller 150 and stored in the memory 154. [ The memory 154 stores the RGB data and outputs the previous frame data of the RGB data input to the timing controller 150 to the timing controller 150. [

The host system 180 converts the resolution of the image data RGB input from the outside into the resolution of the display panel 10 and outputs various timing signals Vsync, Hsync, DE, CLK, 150). The host system 180 may be an external video source device such as a navigation system, a set-top box, a DVD player, a Blu-ray player, a personal computer (PC) System (Home Theater Sytem) or the like to receive video data. The host system 180 includes a system on chip (hereinafter referred to as " SoC ") including a scaler, and is adapted to display image data from an external video source device on a display panel 100 in a format .

Operation of the time division mode and the space division mode of the stereoscopic image display apparatus of the present invention will be described below. The following description will be made with reference to the components of Figs. 1 and 2 described above.

3 is a diagram illustrating an operation of the stereoscopic image display apparatus according to an exemplary embodiment of the present invention, illustrating the operation of the shutter glasses mode in the time division mode.

Referring to FIG. 3, the stereoscopic image display apparatus of the present invention includes a display panel 10, a pattern leader 17, shutter glasses 30, and the like. When the user selects the shutter glasses type time division mode through the user switching unit 160, the time division mode signal is inputted through the control unit 170. [ When the time-division mode signal is input to the 3D formatter 170, the two-dimensional image data is converted into three-dimensional image data in a time-division mode and is transmitted to the timing controller 150. The timing controller 150 transmits various signals . In addition, the 3D formatter 170 transmits a shutter eyeglasses control signal for controlling the shutter eyeglasses through the shutter eyeglasses control signal transmitting unit 140.

The display panel 10 displays the left eye image and the right eye image in a time-division manner. For example, the left eye image L is displayed on all pixels of the display panel 10 during the n-th (n is a natural number) frame period, and the black image data is displayed on the display panel 10 during the (n + Lt; / RTI > may be displayed on all the pixels of the display. Further, the right eye image R data is displayed on all the pixels of the display panel 10 during n + 2 (n is a natural number) frame period, and the black image data is displayed on the display panel 10 during the (n + Lt; / RTI > may be displayed on all the pixels of the display. In Fig. 3, reference numeral 15 denotes an upper polarizer attached to the upper transparent substrate of the liquid crystal display panel.

The left eye filter of the shutter glasses 30 transmits light of the left eye image L and the black image by being opened in synchronism with the left eye image L and the black image data displayed on the display panel 10, (R) data is displayed at the same time. The right eye filter of the shutter glasses 30 is opened in synchronization with the right eye image R data displayed on the display panel 10 to transmit the light of the right eye image R and the black image, When the left eye image (L) data is displayed, the light is blocked at the same time.

In the case of the 120 Hz shutter glasses 30, the number of parallax images provided in the left eye is two (left eye image and black image), and the number of parallax images provided in the right eye is two (right eye image and black image) , The display panel 10 displays the left eye image L1 in the n-th frame period, the black image in the (n + 1) -th frame period, and the n + 2 The right-eye image R is displayed in the frame period, and the black image is displayed in the (n + 3) -th frame period.

The user can see the left eye image L displayed in the n-th frame period by wearing the shutter glasses 30, and can view the black image displayed in the (n + 1) -th frame period. Then, the right-eye image R displayed in the (n + 2) -th frame period can be seen, and the black image displayed in the (n + 3) -th frame period can be seen. Here, since the shutter glasses 30 have no polarization characteristic, they are not affected by the pattern drawer 17 formed on the display panel 10. [ Accordingly, the user can enjoy the stereoscopic image of the shutter glasses system in which the left eye image and the right eye image are time-divided.

4 is a diagram illustrating an operation of a stereoscopic image display apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the stereoscopic image display apparatus of the present invention includes a display panel 10, a pattern leader 17, polarizing glasses 35, and the like.

The pattern driver 17 is attached to the upper polarizer 15 of the display panel 10. A first retarder is formed on the odd display lines of the pattern driver 17 and a second retarder is formed on the even display lines of the pattern driver 17. The light absorption axis of the first retarder and the light absorption axis of the second retarder are different from each other. The first retarder of the pattern drifter 17 opposes the odd display lines of the pixel array and transmits the first polarized light (circularly polarized light or linearly polarized light) of the light incident from the odd-numbered display lines of the pixel array. The second retarder of the pattern drifter 17 transmits the second polarized light (circularly polarized light or linearly polarized light) of the light incident from the even-numbered display line of the pixel array in opposition to the even-numbered display line of the pixel array. The first retarder of the pattern leader 17 may be implemented as a polarizing filter transmitting vertical line polarization and the second retarder of the pattern leader 17 may be implemented as a polarizing filter transmitting horizontal line polarized light.

The left eye polarizing filter (or the first polarizing filter) of the polarizing glasses 35 has the same optical absorption axis as the first retarder of the pattern leader 17. The right eye polarizing filter (or the second polarizing filter) of the polarizing glasses 35 has the same optical absorption axis as the second retarder of the pattern leader 17. For example, the left eye polarizing filter of the polarizing glasses 35 may be selected as a vertical line polarizing filter, and the right eye polarizing filter of the polarizing glasses 35 may be selected as a horizontal line polarizing filter.

When the user selects the spatial division mode, which is the pattern driven method, through the user switching unit 160, the spatial division mode signal is input through the controller 170. [ When the spatial division mode signal is input to the 3D formatter 170, the two-dimensional image data is converted into three-dimensional image data in the spatial division mode and is transmitted to the timing controller 150. The timing controller 150 transmits the three- It transmits various signals. At this time, the 3D formatter 170 does not transmit any signal to the shutter eyeglasses control signal transmitter 140.

The display panel 10 displays the left-eye image and the right-eye image in a space-division manner. For example, the first left eye image (L1) data is displayed on the odd line of the display panel 10 during the n-th (n is a natural number) frame period, and the first right eye image (R1) data is displayed on the even line. Then, the first 'left eye image (L1') data is displayed on the odd line of the display panel 10 during the (n + 1) -th frame period, and the first 'right eye image (R1') data is displayed on the even line. Further, the second left eye image (L2) data is displayed on the odd line of the display panel 10 during the (n + 2) -th frame period, the second right eye image (R2) data is displayed on the even line, Eye image L2 'data on the odd-numbered line of the display panel 10 during the period, and the second' right-eye image R2 'data is displayed on the odd line.

The first retarder of the pattern drifter 17 splits the linearly polarized light of the first, first, second, and second left eye images L1, L1 ', L2, L2' And the second retarder converts the linearly polarized light of the first, first, second and second 'right-eye images R1, R1', R2, R2 'passing through the display panel 10 into horizontal polarized light Conversion.

Therefore, the left eye polarizing filter of the polarizing glasses 35 transmits only the vertical line polarized light. The horizontal line polarized light passing through the second retarder of the pattern leader 17 does not pass through the left eye polarizing filter. The right eye polarizing filter of the polarizing glasses 35 transmits only the horizontally polarized light. The vertical line polarized light passing through the first retarder of the pattern leader 17 does not pass through the right eye polarizing filter.

If the number of parallax images provided to the left eye is four (first, first, second, and second left eye images) and the number of parallax images provided to the right eye is four (first, first, Second, and second 'right eye images), the display panel 10 performs high-speed driving at 240 Hz to display the first left eye image L1 in the pixels of the odd line in the n-th frame period, The first right-eye image R1 is displayed. The first left eye image L1 'is displayed on the pixels of the odd line in the (n + 1) th frame period, and the first right eye image R1' is displayed on the pixels of the even line. The second left eye image L2 is displayed on the pixels of the odd line in the (n + 2) -th frame period, and the second right eye image R2 is displayed on the pixels of the even line. The second 'left eye image L2' is displayed on the pixels of the odd line in the (n + 3) -th frame period, and the second 'right eye image R2' is displayed on the pixels of the even line.

Therefore, the user can see the first left-eye image L1 and the first right-eye image R1 displayed in the n-th frame period on the fast-driving display panel 10, It is possible to view the 1 'left eye image L1' and the first right eye image R1 ', the second left eye image L2 and the second right eye image R2 displayed in the (n + 2) Eye image L2 'and the second' right-eye image R2 'displayed in the (n + 3) -th frame period.

Accordingly, the user can appreciate the stereoscopic image of the pattern-driven method in which the left eye image and the right eye image are divided into spaces. Although the linear polarization method is described as an example in the present embodiment, a known circular polarization method is also applicable.
