Embodiment 1

[0043] This embodiment provides a method for displaying 3D images, which is applied to an electronic display device including a display screen including a liquid crystal screen. In this embodiment of the application, the liquid crystal screen is 120Hz / 1080P as an example to be specific.

[0044] under, Figure 4 The flow chart of the image display method in the first embodiment, in particular in combination with Figure 4 , to describe in detail the specific implementation process of an image display method in Embodiment 1 of the present application, including the following steps:

[0045] Step S11: Receive a frame of 3D signal.

[0046] In fact, the format of the 3D signal may be a left-right format, a top-bottom format, a row-interleaved radical format, etc., which will not be detailed here.

[0047] Step S12: Process the one frame of 3D signal into a left-eye image signal and a right-eye image signal.

[0048] In fact, in the case of 3D images, the 3D format signal is f...

Embodiment 2

[0078] This embodiment provides a method for displaying 3D images, which is applied to an electronic display device including a display screen including a liquid crystal screen. In this embodiment of the application, the liquid crystal screen is 120Hz / 1080P as an example to be specific.

[0079] Next, continue to combine Figure 4 , the following implementation steps are the same as in Embodiment 1, and the following steps are briefly described:

[0080] Step S11: Receive a frame of 3D signal.

[0081] Step S12: Process the one frame of 3D signal into a left-eye image signal and a right-eye image signal.

[0082] Step S13: Displaying four fields of images on the liquid crystal screen based on the left-eye image signal and the right-eye image signal.

[0083] Figure 5 The flow chart of displaying four field images of step S13, as Figure 5 As shown, the specific implementation steps of S13 are as follows:

[0084] Step S21: combined with image 6, when the image is displa...

Embodiment 3

[0096] This embodiment provides a method for displaying 3D images, which is applied to an electronic display device including a display screen including a liquid crystal screen. In this embodiment of the application, the liquid crystal screen is 120Hz / 1080P as an example to be specific.

[0097] Next, continue to combine Figure 4 , the following implementation steps are the same as in Example two, and the following steps are briefly described:

[0098] Step S11: Receive a frame of 3D signal.

[0099] Step S12: Process the one frame of 3D signal into a left-eye image signal and a right-eye image signal.

[0100] Step S13: Displaying four fields of images on the liquid crystal screen based on the left-eye image signal and the right-eye image signal.

[0101] continue to combine Figure 5 As shown, the specific implementation steps of S13 are as follows:

[0102] Step S21: combined with image 6, when the image is displayed in the first field, in the display period T 1 In t...

Abstract

The application provides a 3D image display method, a 3D image display device and a television. A frame of 3D image is received and displayed as four fields of images; when the first field of left-eye image is displayed, the displayed image is rapidly refreshed in a cycle T1, and in a display cycle t1, the left-eye image is then kept; when the second field of dark-field image is displayed, the displayed dark-field image is rapidly refreshed in a cycle T2, and in a display cycle t2, the dark-field image is then kept; likewise, when the third field of right-eye image is displayed, the displayed image is rapidly refreshed in a cycle T3, and in a display cycle t3, the right-eye image is then kept; when the fourth field of dark-field image is displayed, the displayed dark-field image is rapidly refreshed in a cycle T4, and in a display cycle t4, the dark-field image is then kept. Compared with the prior art, the invention optimizes the problem of 3D crosstalk by increasing the image-refreshing speed, thus further increasing the brightness of 3D display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method, device and television for displaying 3D images. Background technique [0002] figure 1 It is the realization schematic diagram of the shutter type 3D display technology, refer to figure 1 , in the shutter-type 3D display technology, the left and right eye images are displayed alternately, specifically: when the right eye image needs to be displayed, the right lens is turned on and the left lens is turned off; when the left eye image needs to be displayed, the left lens is turned on and the right lens is turned on Close, and in the whole process, the refresh timing of the left and right eye images is synchronized with the switching timing of the left and right lenses of the glasses, so as to ensure that the left eye of the person can see the left eye image of each frame of image through the left lens of the 3D glasses, The right eye of the guarantor can see th...
