3D (Three-dimensional) liquid crystal display and anti-crosstalk method thereof

Abstract

The invention provides a 3D (Three-dimensional) liquid crystal display and an anti-crosstalk method thereof. The 3D liquid crystal display comprises a general display area and a dark line display area, wherein the general display area comprises a first pixel electrode and a first switching unit; the dark line display area comprises a second pixel electrode and a second switching unit; the first switching unit comprises a first grid connected with a scanning line, a first source connected with a data line, and a first drain connected with the first pixel electrode; and the second switching unit comprises a second grid connected with a public electrode line, a second source connected with the first drain, and a second drain connected with the second pixel electrode. According to the 3D liquid crystal display, the problem of the conventional polarized 3D crosstalk is solved, normal display of pixels is maintained when 2D (two-dimensional) pictures are displayed on the liquid crystal display, a polarized film does not have any dark line region, and the transmittance of the displayed 2D pictures is not influenced by the existence of the dark line region; and in a 3D display mode, the dark line region for relieving 3D problems is formed in a pixel area, so that the 3D picture display quality is improved.

Description

technical field [0001] The invention relates to a polarized 3D liquid crystal display and a method for preventing crosstalk. Background technique [0002] FPR (Film-type Patterned Retarder, polarized) is one of the existing imaging methods of 3D liquid crystal display. figure 1 Shown is a schematic diagram of an existing polarized 3D liquid crystal display. The polarized 3D liquid crystal display device includes a liquid crystal display panel 10, a polarizer 20 positioned in front of the liquid crystal display panel 10, and a 3D polarizing film (Patterned Retarder) attached to the polarizer.

Problems solved by technology

When displaying the 2D viewing state, the viewer does not need to wear polarized glasses. Generally, a row of pixels of the liquid crystal display panel provides the viewer's left eye to watch through the 1 / 4λ reflection wavelength, and a row of pixels provides the right eye to watch through the 3 / 4λ reflection wavelength; When displaying the 3D viewing state, the viewer needs to wear polarized glasses 40. Generally, a row of pixels of the liquid crystal display panel provides the viewer's left eye to view through the 1 / 4λ reflection wavelength, and a row of pixels provides the right eye to view through the 3 / 4λ reflection wavelength. However, when the 3D polarizing film 30 is attached to the liquid crystal display panel 10 with deviations in accuracy or squinting, the signal to the left eye of the viewer is seen by the right eye, or the signal to the right eye is seen by the left eye, forming a crosstalk problem. Human eyes feel uncomfortable, and the LCD screen display quality is not good

[0003] figure 2 It is a schematic diagram of the existing improved crosstalk method. The improved crosstalk method is to add black stripes (black) 50 at the 1 / 4λ reflection wavelength and 3 / 4λ reflection wavelength of the 3D polarizing film 30, although it can reduce Crosstalk, but the width of the black stripe 50 must be larger, which seriously affects the transmittance in 2D display
