Problems solved by technology

The black image does not belong to the left-eye image nor the right-eye image. Although this liquid crystal display driving method can reduce the image crosstalk to a certain extent, at the same time, due to the insertion of the black image, the brightness of the image is lower than that of inserting a frame of black. The image has been greatly reduced before, which to a certain extent has brought about the loss of the 3D display effect of the LCD screen

Embodiment 1

[0071] In this embodiment, the method for optimizing the liquid crystal screen and the device LCD TV will be described with an 8-bit liquid crystal screen that displays 240 frames of images within 1 second. And the specific steps of time-sharing display of the first left-eye image, the first right-eye image, the second left-eye image, and the second right-eye image with grayscale values ​​of 4 frames of 40, 50, 30, and 20 in sequence are described as an example. Invention, the liquid crystal screen of this embodiment is compared with the liquid crystal screen of the same specification that uses the black insertion technology to avoid the crosstalk between the left eye image and the right eye image. While reducing the crosstalk, the brightness of the liquid crystal screen is improved. The specific steps are as follows:

[0072] S1 First left-eye image display: The gate line of the LCD screen receives the left-eye image scanning command, and the data pole line of the LCD screen r...

Embodiment 2

[0089]In this embodiment, the method for optimizing the liquid crystal screen and the device liquid crystal TV are described with a 10-bit liquid crystal screen that displays 240 frames of images within 1 second. And the specific steps of the time-sharing display of the first left-eye image, the first right-eye image, the second left-eye image, and the second right-eye image with the gray scale values ​​of 4 frames being 126, 140, 180, and 100 in sequence are described as an example. Invention, the liquid crystal screen of this embodiment is compared with the liquid crystal screen of the same specification that uses the black insertion technology to avoid the crosstalk between the left eye image and the right eye image. While reducing the crosstalk, the brightness of the liquid crystal screen is improved. The specific steps are as follows:

[0090] S1 First left-eye image display: The gate line of the LCD screen receives the left-eye image scanning command, and the data pole li...

Embodiment 3

[0100] In this embodiment, the method for optimizing the liquid crystal screen and the device liquid crystal TV are described with a 6-bit liquid crystal screen that displays 240 frames of images within 1 second. And the specific steps of time-sharing display of the first left-eye image, the first right-eye image, the second left-eye image, and the second right-eye image with the grayscale values ​​of 4 frames of 20, 30, 15, and 16 in sequence are described as an example. Invention, the liquid crystal screen of this embodiment is compared with the liquid crystal screen of the same specification that uses the black insertion technology to avoid the crosstalk between the left eye image and the right eye image. While reducing the crosstalk, the brightness of the liquid crystal screen is improved. The specific steps are as follows:

[0101] S 1 First left-eye image display: the gate line of the LCD screen receives the left-eye image scanning command, and the data pole line of the L...

Abstract

The invention discloses a method and device for optimizing the 3D (three dimensional) display effect of an LCD (liquid crystal display) screen, and a LCD television, and mainly aims to provide a method for optimizing the 3D display effect of the LCD screen, which reduces LCD screen crosstalk and improves the display brightness of the LCD screen. According to the method for optimizing the 3D display effect of the LCD screen, image data is received by the LCD screen for carrying out left eye image scanning and right eye image scanning alternately, the insertion time domain of one frame of gray image is set after the scanning of one frame of left eye image is ended, and within the time domain, a preset gray scale voltage which is greater than 0 gray scale and smaller than 32 gray scales is input to the LCD screen, so that the scanning of one frame of gray image is carried out by the LCD screen, and the frame of gray image is displayed; and the insertion time domain of one frame of gray image is set after the scanning of a frame of right eye image is ended, and within the time domain, a preset gray scale voltage which is greater than 0 gray scale and smaller than 32 gray scales is input to the LCD screen, so that a frame of gray image is displayed by the LCD screen. The method disclosed by the invention is easy to realize and operate, and is low in cost.

Description

technical field [0001] The invention relates to a method and device for optimizing the 3D display effect of a liquid crystal screen and a liquid crystal television. Background technique [0002] With the rapid development of 3D display technology, 3D LCD screens have become increasingly common. The existing 3D LCD screens are mainly divided into glasses-type naked-eye types. At the same time, it is relatively cost-effective and has gradually become the mainstream in existing 3D LCD screen products. The shutter-type 3D LCD screen divides the image into two by increasing the screen refresh rate to form two sets of images corresponding to the left and right eyes of the user. When the LCD screen displays the image for the right eye, the right lens is turned on and the left lens is closed, and the left lens is turned on when the image for the left eye is displayed. The left lens closes the right lens, and each frame of picture enters the left and right eyes of the person respect...
