Embodiment 1

[0044] Such as Image 6 As shown, the passive polarized 3D display device using a patterned retardation film according to Embodiment 1 of the present invention includes: a backlight unit 1, a first polarizer 2, a TFT array substrate 3, a color filter substrate 4, and a second polarizer arranged in sequence. sheet 12 and pattern retardation film 5. A passive polarizing 3D display device using a patterned retardation film according to Embodiment 1 of the present invention and figure 1 The difference of the passive polarizing 3D display device using the pattern retardation film in the prior art shown is that not only matrix strips are arranged on the film surface of the color filter substrate 4, but also light-shielding strips are arranged on the back of the color filter substrate 4 8, and the light-shielding strips 8 on the back of the color filter substrate 4 have the same width and equal spacing as the matrix strips on the film surface of the color filter substrate 4, so as t...

Embodiment 2

[0054] Such as Figure 7 As shown, the passive polarized 3D display device using the pattern retardation film according to Embodiment 2 of the present invention includes: a backlight unit 1, a first polarizer 2, a TFT array substrate 3, a color filter substrate 4, and a second polarizer arranged in sequence. sheet 12 and pattern retardation film 5. The passive polarized 3D display and figure 1 The difference of the passive polarizing 3D display device using the pattern retardation film in the prior art shown is that: a light-shielding strip 8 is provided on the back of the color filter substrate 4, and the corresponding position of the film surface of the color filter substrate 4 may not be provided with a matrix. strip. Wherein, the dividing line between two adjacent pattern phase difference films is opposite to the middle position of the light-shielding strip 8 on the back side of the color filter substrate 4 corresponding to the dividing line; the preferred mode of relati...

Abstract

The invention discloses a passive polarizing type three-dimensional (3D) display device using a pattern phase difference diaphragm. The passive polarizing type 3D display device comprises a back light unit, a polaroid, an array base plate, a color film base plate and the pattern phase difference diaphragm, wherein one side on the color film base plate, far away from the array base plate, is provided with a plurality of light shielding strips, and the middle position of each light shielding strip corresponds to the position of a boundary between two adjacent pattern position phase difference films on the corresponding pattern difference diaphragm. When the passive polarizing type 3D display device is adopted, the vertical visual angle of the visual angle 3D display using the pattern phase difference diaphragm can be increased. In addition, compared with other modes for improving the vertical visual angle, the passive polarizing type 3D display device can solve the problems of poor moir and low aperture opening ratio during 3D display.

Description

technical field [0001] The invention relates to the field of three-dimensional (3D) display, in particular to a passive polarized 3D display device using a pattern retardation film. Background technique [0002] Such as figure 1 As shown, the passive polarized 3D display device using the pattern retardation film in the prior art includes: a backlight unit 1, a first polarizer 2, an array substrate 3, a color filter substrate (CF) 4, a second polarizer arranged in sequence sheet 12 and a patterned retarder film (Patterned Retarder Film) 5; wherein, the side of the color filter substrate 4 facing the array substrate 3 (this side is called the film surface) is provided with a black matrix, and the black matrix has a plurality of matrix bars 41 . The vertical viewing angle B=arc sin(refractive index×sin(A)) of the passive polarized 3D display using the pattern retardation film, the angle A=2arc tan(h / 2D); wherein, the refractive index can be taken as an empirical value of 1.5,...
