[0049] Figure 4 It is a schematic diagram of a driving method of a stereoscopic display according to an embodiment of the present invention. Please also refer to figure 1 as well as Figure 4 , in this embodiment, the display panel unit DP successively displays the right-eye image R and the left-eye image L according to the image synchronization control signal V-syn, and each image (right-eye image R or left-eye image L) is displayed from From the first image data area D1 of the panel unit DP to the Nth image data area Dn (such as Figure 3A Shown) the update time is T. In more detail, when the control unit C receives the image synchronization control signal V-syn, the control unit C controls the display panel unit DP to start updating the right-eye image R from the first image data area D1. When the control unit C receives the next image synchronization control signal V-syn, the control unit C controls the display panel unit DP to start updating the left-eye image L from...

[0059] Figure 8 It is a schematic diagram of a driving method of a stereoscopic display according to an embodiment of the present invention. Please also refer to figure 1 and Figure 8 , in this embodiment, the display panel unit DP includes a first time interval T1 and a second time interval T2 during displaying the right-eye image R (or left-eye image L). Here, the first time interval T1 and the second time interval T2 are, for example, 1 / 240 second respectively, but the present invention is not limited thereto.

[0060] As mentioned above, the display panel unit DP continues to display the previous image (for example, the left-eye image L) in the first time interval T1, and displays the image (for example, the right-eye image R) in the second time interval T2. renew.

Abstract

A stereo display including a display panel unit, a phase modulator unit, a backlight unit and a control unit is described. The display panel unit sequentially displays a right eye image and a left eye image according to an image synchronizing control signal. The phase modulator unit is disposed at one side of the display panel unit and is sequentially switched to be a right eye phase and a left eye phase. The backlight unit is disposed at the other side of the display panel unit and is turned on and turned off repeatedly. The control unit is electrically connected to the display panel, the phase modulator unit and the backlight unit and controls the phase modulator unit and the back light unit according to the image synchronizing control signal.

Description

technical field [0001] The present invention relates to a stereoscopic display and its driving method, and in particular to a stereoscopic display using polarized glasses and its driving method. Background technique [0002] In terms of current display technologies, stereoscopic displays can be broadly classified into stereoscopic displays, in which viewers need to wear specially designed glasses, and auto-stereoscopic displays, in which viewers directly view them with naked eyes. The naked-eye stereoscopic display allows multiple images from different viewing angles to enter the left and right eyes respectively, and stereoscopic images can be seen without special glasses. Multiple images with different viewing angles can be displayed in the horizontal direction. However, the problem with the naked-eye stereoscopic display is that once the position of the eyes deviates from the designated position, there will be no stereoscopic display effect. [0003] Currently, stereosco...
