Abstract
A liquid crystal display device and a method of driving the same comprising first and second XY-matrix liquid-crystal display panels provided with a switching device every pixel, and liquid crystal drives to supply video signals whose polarities are inverted every predetermined cycle to first and second liquid-crystal display panels so that the polarities of video signals supplied to the first and second liquid-crystal display panels simultaneously may be reverse to each other.
Claims22
A liquid crystal display device comprising:
- first and second liquid-crystal display panels in each of which a plurality of pixels each provided with a switching device are arrayed in a matrix;
- driving means for driving said first and second liquid-crystal display panels so that they may be inverted;
- and
- generation means for generating signals for inverting polarities of video signals supplied to said first and second liquid-crystal display panels simultaneously with each other,
- wherein said first liquid-crystal display panel is dedicated to either a user's left or right eye and said second liquid-crystal display panel is dedicated to the user's other eye.
A liquid crystal display device comprising:
- first and second XY-matrix liquid-crystal display panels each having a plurality of pixels, wherein switching and storage devices are provided for every pixel;
- and
- a liquid crystal drive to supply video signals, whose polarities are inverted every predetermined cycle, to said first and second liquid-crystal display panels so that the polarities of video signals supplied to said first and second panels simultaneously may be reversed with respect to each other,
- wherein said first liquid-crystal display panel is arranged in a position such that it can be seen only with a user's right eye and said second liquid-crystal display panel is arranged in a position such that it can be seen only with the user's left eye.
A method of driving a liquid crystal display device provided with first and second XY-matrix liquid-crystal display panels each having a plurality of pixels and in which a switching device is provided for every pixel, said method comprising the steps of:
- simultaneously supplying video signals whose polarities are inverted every predetermined cycle to the first and second liquid-crystal display panels, respectively;
- and
- reversing the polarities of video signals simultaneously supplied to the first and second liquid-crystal display panels with respect to each other,
- wherein the first liquid-crystal display panel is dedicated to either a user's right or left eye and the second liquid-crystal display panel is dedicated to the user's other eye.
A head mount display comprising:
- display panels for right and left eyes each wired in a matrix arrangement;
- and
- a driving circuit for inverting the polarities of image signals per a predetermined period, and outputting the inverted image signals simultaneously to said display panels for the right and left eyes,
- wherein said driving circuit outputs, to said display panels for the right and left eyes, the image signals inverted to each other.
A method for driving a head mount display, said method comprising the steps of
- inverting the polarity of an image signal per a predetermined period;
- and
- outputting to a display panel for a right eye and to a display panel for a left eye,
- wherein in said outputting step image signals the polarities of which have been inverted with respect to each other are respectively outputted simultaneously to the display panels for the right and the left eyes.
