Abstract

A three-dimensional image display device (100) comprises a display panel (102), a patterned phase retardation film (108) and a barrier layer (104). The display panel (102) comprises several scan lines (200s), several first data lines (201d), several second data lines (202d), and several pixel units (204). Each of the pixel units (204) comprises a primary pixel (204m), a first secondary pixel (204s1), and a second secondary pixel (204s2). The primary pixel (204m) is coupled to a scan line (200s) in the scan lines (200s) and a first data line (201d) in the first data lines (201d) through a first thin-film transistor (206a), and the first secondary pixel (204s1) and the second secondary pixel (204s2) are coupled to the scan line (200s) and a second data line (202d) in the second data lines (202d) through a second thin-film transistor (206b). The patterned phase retardation film (108) is disposed between the display panel (102) and polarized glasses (107), and receives light passing through the display panel (102) to change the light to linearly polarized light in vertical and horizontal directions.

Description

【Technical field】 [0001] The invention relates to an image display device, and in particular to a three-dimensional image display device with a patterned phase retardation film. 【Background technique】 [0002] A 3D image display device (ie, a stereoscopic image display device) uses stereoscopic technology or autostereoscopic technology to display 3D images. Stereoscopic technology achieves a three-dimensional effect through the parallax images of the left and right eyes of the user. The stereoscopic technology includes a method with glasses and a method without glasses, which have been put into practical application. In the glasses method, by changing the polarization direction of the left and right parallax images, the left and right parallax images are displayed on a display device based on direct vision. The stereoscopic image is realized by using polarized glasses, for example, a patterned phase retardation film (film-type patterned retarder, FPR) is used in liquid crys...
