立体显示器、立体显示器的显示方法及立体画面显示方法 Stereoscopic display and the stereoscopic display method for displaying a stereoscopic picture display method

技术领域 FIELD

[0001] 本发明关于一种立体显示装置及其显示方法,尤指一种配合偏光眼镜达到立体显示效果的立体显示器、立体显示器的显示方法及立体画面显示方法。 [0001] The present invention relates to a display apparatus and a stereoscopic display method, particularly to a stereoscopic display with polarized glasses to achieve a stereoscopic display, the stereoscopic display method and a stereoscopic display screen display method.

背景技术 Background technique

[0002] 立体显示技术由于可提供观看者生动的立体图像,已成为现今显示技术发展的重要方向之一。 [0002] Since the three-dimensional display technology can provide a vivid three-dimensional image of the viewer, has become an important direction of technology development today show. 已知技术中包括空间式立体显示技术,其原理是使显示面板同时显示出两组分别供左眼及右眼观看的画面,并使观看者的左眼仅接收左眼画面,右眼仅接收右眼画面。 Known art includes a spatial stereoscopic display technology, the principle is that the display screen of the display panel simultaneously for the two groups of the left and right eyes view, and the viewer's left eye receives only the left-eye picture, the right eye receives only right eye images. 然而,由于显示面板必须同时显示出两组画面,因此在有些情况下解析度会下降50%,所以具有低解析度的缺点。 However, since the display panel must show two screens simultaneously, in some cases resolution will fall by 50%, it has the disadvantage of low resolution.

[0003] 随之出现了相差扫描式立体显示(farming retarder type 3D)技术,其是利用时间上来区分两眼的独立图像,通过偏光眼镜配上一片偏光面板来达到选择两眼图像的机制。 [0003] Scanning a phase difference appears stereoscopic display (farming retarder type 3D) technology, which uses up time to distinguish two separate images, coupled with a polarization panel polarizing glasses is achieved by selecting two images mechanism. 具体而言,如图1所示,为已知的立体显示装置的运作示意图。 Specifically, as shown in FIG. 1, a schematic view of the operation of the display device are known perspective. 已知的立体显示装置主要包括背光模块10、显示面板12及偏光面板14。 Known stereoscopic display device mainly includes a backlight module 10, a display panel 12 and the polarizer panel 14. 于显示画面时,显示面板12会以扫描方式显示所需要的画面。 When in the display screen, the display screen of the display panel 12 will be required in a scanning manner. 偏光面板14与显示面板12同步扫描此画面并改变画面的偏光角度, 以交替显示供左眼观看的左眼画面18及供右眼观看的右眼画面19。 Polarization panel 14 and the display panel 12 synchronously scanning this screen and changing the polarization angle of the screen to display alternately for the left-eye picture and the right-eye viewing screen 18, 19 for the right eye. 于观看画面时,观看者配戴一副偏光眼镜20,分别接收供左眼观看的左眼画面18及供右眼观看的右眼画面19。 At the time of watching the screen, a viewer wearing polarized glasses 20, each for receiving a left-eye picture and the right-eye viewing screen 18 for viewing the eye 19.

[0004] 如图1所示,显示面板12依圆形箭号的方向依序显示出一个完整图框的流程,其中完整图框包括左眼画面图框与右眼画面图框。 [0004] As shown in FIG 1, the display panel 12 by sequentially direction of circular arrow shows a flow of a complete frame, wherein the frame comprises a complete frame picture left-eye pictures and right-eye frame. 图1的上半部绘示了由显示面板12开始连续且渐进地进行左眼画面18的扫描,而偏光面板14与显示面板12作同步扫描,因此偏光面板14的一个特定偏光模式一直与左眼画面18对应,而另一偏光模式则一直与右眼画面19对应。 The upper half of Figure 1 shows a scanning 18 12 starts progressively and continuously performed by the left-eye picture display panel, the polarization panel 14 and the display panel 12 synchronously scan, so a particular polarization mode of a polarization panel 14 has been left 18 corresponding to the eye frame, and the other has the polarization mode screen 19 corresponding to the right eye. 图1的下半部则绘示了显示面板12开始连续且渐进地进行右眼画面19的扫描,同样地通过偏光面板14与显示面板12的同步扫描。 The lower half of Figure 1 shows the display panel 12 continuously and progressively begin to scan the eye frame 19, 14 by synchronously scanning the same manner as the polarizing plate and the display panel 12.

[0005] 然而,由于偏光面板14是用以对画面做偏振态的调整,左眼画面和右眼画面分别对应不同的两种偏光模式,该偏光面板14切换该两种偏光模式以提供左右眼画面,其操作状态为在打开与关闭之间做切换,以交替显示左右眼观看的画面。 [0005] However, since the polarizing screen panel 14 is used to make adjustments to polarization, left-eye picture and the right-eye picture respectively correspond to two different polarization modes, the polarization panel 14 switches the mode to provide two types of polarized left and right eye screen, the operation status is made to switch between open and closed to alternately display left and right eye view images. 因偏光面板打开与关闭时的反应速度不同,即液晶分子在打开(Ton)和关闭(Toff)时的反应速度不同,从而左眼与右眼所看到的正确信号与漏光状况不同,这会造成左眼和右眼的串扰(X-talk)程度不同,使左右眼画面不平衡,而影响到立体图像的品质。 Due to different polarization panel is open and closed when the reaction rate, i.e., the liquid crystal molecules of different reaction rates in the open (Ton) and off (Toff of), so that different left and right eyes see the right signals and light leakage condition, it will causing the left and right crosstalk (X-talk) to varying degrees, the left and right eye images imbalance affect the quality of the stereoscopic image.

[0006] 如图2所示,为已知技术中偏光面板扫描左眼画面时的波形示意图,在此以左眼对应的偏光模式为偏光面板14开启时的偏光角度为例。 [0006] As shown in FIG 2, is a waveform diagram when the polarization panel scanning technique known left-eye picture, this corresponds to the left eye polarization mode of a polarization angle of the polarization panel 14 is turned on for example. 图中波形A代表显示面板12显示的图像信号。 FIG waveform A represents a display image signal to the display panel 12. 波形B代表偏光面板14对左眼信号的反应曲线。 The reaction profile waveform B represents the left eye polarization panel 14 signals. 波形C代表通过偏光面板14后显示的正确信号。 Waveform C represents a correct signal by the polarizer 14 after the display panel. 波形D代表通过偏光面板14后显示的错误信号,即漏光状况。 An error signal representative of the waveform D after the display panel 14 through the polarization, i.e., light leakage condition. 在图2中,以显示面板12的打开(Ton)和关闭(Toff)速度均较快于偏光面板14为例。 In FIG. 2, to open the display panel 12 (Ton) and off (Toff of) fast-rate to the polarization panel 14 as an example. 图2 中,从上至下四个帧的时序图依次为显示面板12显示左眼信号为白(亮)光、右眼信号暗(黑)光及偏光面板14为先开后关时的帧时序图、显示面板12显示左眼信号为暗(黑)光、右眼信号白(亮)光及偏光面板14为先开后关时的帧时序图、通过偏光面板14后正确信号的时序图及通过偏光面板14后错误信号的帧时序图。 In FIG. 2, a timing diagram from top to bottom four frames are sequentially displayed to the display panel 12 to white (bright) light, the right-eye signal dark (black) light and the polarization panel 14 when the left-eye signal of the first switch timing diagram, the display panel 12 displays the left-eye signal of a dark (black) light, the right-eye signal of white (light) polarized light and the panel frame 14 is a timing chart when the first switch, a timing chart of a correct signal by the polarization panel 14 and FIG frame timing after the error signal 14 by the polarization panel. 图中,每个帧时序图均以两帧信号为一个周期。 FIG., Each frame are two timing chart of a signal cycle.

[0007] 如图3所示,为已知技术中偏光面板扫描右眼画面时的波形示意图,在此以右眼对应的偏光模式为偏光面板14关闭时的偏光角度为例。 [0007] As shown in FIG 3, is a waveform diagram when the panel scanning technique polarized right-eye picture is known, this corresponding to a right eye polarization mode of a polarization angle of the polarization panel is closed Example 14. 图中波形A代表显示面板12显示的图像信号。 FIG waveform A represents a display image signal to the display panel 12. 波形E代表偏光面板14对右眼信号的反应曲线。 Waveform E represents the polarization panel 14 to the right-eye signal response curve. 波形F代表通过偏光面板14后显示的正确信号。 F represents a correct signal waveform by the polarizer 14 after the display panel. 波形G代表通过偏光面板14后显示的错误信号,即漏光状况。 G represents a waveform of an error signal after the display panel 14 through the polarization, i.e., light leakage condition. 在图3中,以显示面板12的打开(Ton)和关闭(Toff)速度均较快于偏光面板14为例。 In Figure 3, to open the display panel 12 (Ton) and off (Toff of) fast-rate to the polarization panel 14 as an example. 图3 中,从上至下四个帧时序图依次为显示面板12显示右眼信号为白(亮)光、左眼信号为暗(黑)光及偏光面板14为先关后开时的帧时序图、显示面板12显示右眼信号为暗(黑) 光、左眼信号为白(亮)光及偏光面板14为先关后开时的帧时序图、通过偏光面板14后正确信号的时序图及通过偏光面板14后错误信号的帧时序图。 In Figure 3, four frames from top to bottom is a timing chart of the display panel 12 sequentially displays the right-eye signal of a white (bright) light, the left-eye signal of a dark (black) light and the polarization panel 14 is opened after the first frame when off a timing chart showing a timing signal after the correct panel 12 displays the right eye dark signal (black) light, the left-eye signal of a white (bright) off after the first frame 14 is a timing chart when the opening panel and the polarization by the polarization panel 14 and FIG frame timing after the error signal by the polarization panel 14. 图中,每个帧时序图均以两帧信号为一个周期。 FIG., Each frame are two timing chart of a signal cycle.

[0008] 串扰(X-talk)程度的定义为错误信号亮度与正确信号亮度之比。 [0008] Crosstalk (X-talk) is defined as the ratio of the degree of the error signal and the luminance signal of the correct brightness. 由图2和图3 所示波形可以得出,图3中所示的眼镜20所接收的右眼信号的串扰度明显大于左眼信号的串扰度,如此,左右两眼看到的图像容易出现重影、晕轮效应等不良现象,从而影响立体画面的图像效果。 Can be derived from the waveforms shown in FIG. 2 and FIG. 3, shown in FIG. 3 glasses 20 of the right-eye crosstalk received signal is significantly greater than the crosstalk of the left-eye signal, and so, the left and right eyes see the image is prone to heavy Movies undesirable phenomenon, the halo effect, etc., thus affecting the image quality of a stereoscopic picture.
