Embodiment approach 1

[0061] based on Figure 1~5 A first embodiment of the display device according to the present invention will be described.

[0062] (display device 1)

[0063] figure 1 It is a block diagram showing a main part configuration of a display system according to an embodiment of the present invention. As shown in the figure, the display system includes a display device 1, a video signal source 2, shutter glasses 14a, and shutter glasses 14b. Here, the display device 1 includes a video signal control unit 4 , a frame memory 5 , a shutter glass control unit 6 , a backlight control unit 7 , a timing control unit 8 , and a display unit 9 . In addition, the video signal control unit 4 includes a black line insertion unit 3 . Furthermore, the display unit 9 includes a display panel 12 , a gate driver 10 , a source driver 11 , and a backlight 13 . The display device 1 is connected to a video signal source 2 .

[0064] (Video source 2)

[0065] The video signal source 2 is, for exa...

Embodiment approach 2

[0103] Below, refer to Image 6 A second embodiment of the present invention will be described. In addition, the same code|symbol is attached|subjected to each component which is the same as that of 1st Embodiment mentioned above, and detailed description is abbreviate|omitted.

[0104] In the display device 1 of the present embodiment, the video signal control unit 4 generates a video signal having a structure in which two frames of video 15a for the viewer 24a and two frames of video 15b for the viewer 24b are alternately arranged. At this time, the black line insertion unit 3 inserts black lines 31 into odd-numbered lines of each video image 15a, and inserts black lines 31 into even-numbered lines of each video image 15b. Thus, the video signal control unit 4 obtains Image 6 The video signal of the structure shown.

[0105] Image 6 It is a figure which shows the video signal in this embodiment. As shown in the figure, black lines 31 are inserted into the odd-numbered...

Embodiment approach 3

[0108] Below, refer to Figure 7 ~ Figure 9 A third embodiment of the present invention will be described. In addition, the same code|symbol is attached|subjected to each component which is the same as that of the said 1st or 2nd embodiment, and detailed description is abbreviate|omitted.

[0109] Figure 7 It is a block diagram showing the configuration of main parts of the display system according to the third embodiment of the present invention. As shown in the figure, the display system of this embodiment includes a display device 1 , a video signal source 2 , shutter glasses 14 a , shutter glasses 14 b , and shutter glasses 14 c . The configuration of the display device 1 according to the present embodiment is the same as that of the display device 1 according to the first embodiment. However, unlike the first embodiment, the shutter glasses control unit 6 transmits a control signal to the shutter glasses 14c in addition to the shutter glasses 14a and 14b. A viewer 24...

Abstract

A black line inserting section (3) inserts first grayscale inserts first grayscale lines, each of which has a color of certain grayscale and has a width corresponding to a certain number of pixels, into each of first video images such that a certain distance is secured, between the respective first grayscale lines, in a vertical or horizontal direction of each of the first video images. The black line inserting section (3) also inserts second grayscale lines into each of second video images, which corresponds to a certain number of frames and by which a corresponding one of the first video images is followed, such that the second grayscale lines are not inserted into second parts corresponding to first parts where the respective first grayscale lines are inserted.

Description

technical field [0001] The present invention relates to a video signal control device and a video signal control method for processing a video signal having one video per frame, and a display device including the video signal control device. Background technique [0002] Conventionally, a display device is known in which multiple people can simultaneously view different videos on one display screen. Such a display device is configured to alternately input and output video data for each viewer. Viewers are required to wear active shutter glasses. By synchronizing the switching of the video displayed on the display device with the switching of the active shutter glasses (showing the field of view of the glasses (the viewer's field of view) or blocking the field of view), the switching is performed at high speed, so that multiple people can use 1 different display screens to watch their different videos. Such a display device is called an active shutter dual view display. H...
