Stereoscopic display device
A stereoscopic display device may include a light control panel on a display panel, so that light emitted from the display panel may emit in a direction different from adjacent frame and the visibility of the stereoscopic image which is provided to user may be increased without the deterioration of the resolution.
1. A stereoscopic display device comprising:
a display panel;
a display driver driving the display panel;
a light control panel disposed on the display panel, the light control panel including a water layer and an oil layer which are stacked between a first control substrate and a second control substrate;
a control panel driver controlling the light control panel,
a combiner on the light control panel, the combiner having inclination with respect to a surface of the light control panel; and
a convex lens between the light control panel and the combiner,
wherein the combiner includes a beam splitter, so that a virtual image generated by the display panel and the light control panel is realized on an actual image generated by light passing through the combiner,
wherein the control panel driver changes a moving direction of light passing through the light control panel during each frame,
wherein the light control panel further includes lower control electrodes on the first control substrate, a first upper control electrode on the second control substrate, and a second upper control electrode spaced away from the first upper control electrode on the second control substrate,
wherein the water layer is disposed between the lower control electrodes, and the oil layer is disposed between the first upper control electrode and the second upper control electrode,
wherein a moving direction of light emitted from the display panel is changed during each frame and the light emitted from the display panel is crossed between the display panel and the light control panel, and
wherein the light control panel changes the moving direction of the light emitted from the display panel to be parallel with each other.
2. The stereoscopic display device according to claim 1 , wherein the display panel displays an image in a time-division by the display driver.
3. The stereoscopic display device according to claim 1 , wherein the water layer is in contact with the first control substrate, and the oil layer is in contact with the second control substrate.
4. The stereoscopic display device according to claim 1 , wherein an interface between the water layer and the oil layer is changed during each frame.
5. The stereoscopic display device according to claim 1 , wherein a voltage difference between the first upper control electrode and the second upper control electrode is changed by the control panel driver during each frame.
6. The stereoscopic display device according to claim 1 , wherein the display panel includes a light-emitting element between a first display substrate and a second display substrate.
7. The stereoscopic display device according to claim 1 , further comprising a micro-lens array between the display panel and the light control panel.
