Embodiment Construction

[0026] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be practiced.

[0027] see image 3 , image 3 The stereoscopic display device 30 according to the first embodiment of the present invention includes a substrate 300 , a phase retardation film 302 and a plurality of rows of pixel regions. image 3 Four rows of pixel regions 304 , 306 , 308 , and 310 are disposed on the substrate 300 . The substrate 300 is, for example, a thin film transistor array substrate. The phase retardation film 302 is arranged on the pixel areas 304, 306, 308, and 310 and includes a plurality of 1 / 4λ films and -1 / 4λ films arranged vertically alternately, such as image 3 The " / " and "\" shapes shown correspond to the pixel areas 304, 306, 308, 310 and are arranged vertically alternately.

[0028] Each of the pixel areas 304, 306, 308, and 310 includes a plurality of pixel units 312, eac...

Abstract

The invention relates to a stereoscopic display device, which comprises a substrate, multiple rows of pixel regions and a phase retardation film. These pixel areas are arranged on the substrate. Each of these pixel areas includes a plurality of pixel units. Each pixel unit includes a first electrode and a second electrode. The phase retardation film is disposed on these pixel regions. These pixel areas are divided into multiple groups, each group includes N rows of pixel areas, the first electrode of each pixel unit in the first N / 2 rows of pixel areas of each group is one of the "<" type and ">" type, each group The first electrode of each pixel unit in the rear N / 2 row pixel area is the other one of the """ type and """ type that is different from the first electrode of each pixel unit in the front N / 2 row pixel area . N is a positive even number greater than or equal to 4. The invention can solve the problems of color shift and inconsistent brightness in the prior art.

Description

technical field [0001] The invention relates to a display device, in particular to a stereoscopic display device. Background technique [0002] With the development of liquid crystal display devices, 3D display devices capable of presenting stereoscopic images have gradually entered the market and will become the development direction of the next generation of liquid crystal display devices. [0003] see figure 1 , figure 1 It is a schematic diagram of the working principle of the existing stereoscopic display device. figure 1 The existing stereoscopic display device adopts a phase retarder (pattern retarder) technology, which cooperates with polarized glasses 14 to present a stereoscopic image. [0004] Such as figure 1 As shown, a linear polarizer 10 is arranged on one side of a thin film transistor array substrate (ThinFilm Transistor array substrate; TFT array substrate, not shown) of a stereoscopic display device, and a color filter substrate (Color Filter substrate...
