BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a three-dimensional (3D) display area and, more particularly, to a display panel and a three-dimensional (3D) display device.

2. Description of Related Art

The current arrangement of pixels of the display panel includes a horizontal type and a vertical (the Tri-gate) type. In the horizontal type, sub-pixel units (RGB sub-pixel) are horizontally arranged. In the vertical type, the sub-pixel units are vertically arranged.FIG. 1shows the schematic drawing of a display panel of the vertical type. The following uses one pixel structure as example for description. As shown inFIG. 1, the display device includes the relative disposition of the thin film transistor substrate and a color filter substrate. Multiple scan lines G1, G2, G3, and G4, and multiple data lines D1and D2are disposed on the thin-film transistor substrate, and the multiple scan lines G1, G2, G3, and G4, and the multiple data lines D1and D2are cross to define RGB sub-pixel units. The color filter substrate is disposed above the thin film transistor substrate, and a black matrix (BM) layer B1, B2, B3, and B4are disposed on the color filter substrate. Each black matrix layer B1, B2, B3, and B4is correspondingly disposed above the scan lines G1, G2, G3, and G4for separate the color crosstalk of the sub-pixels.

Comparing to the horizontal type, the vertical type shown inFIG. 1can reduce the numbers of the source drivers (Source ICs) which are more expensive component of the display panel, savings cost. Therefore, the display panels with the vertical type are more popular in 3D display device application.

The three-dimensional display method of today's mainstream is using a polarized glasses with phase difference plate technology.FIG. 2is a schematic diagram of the basic operating principle in existing technology. The operating principle is attaching a phase difference plate202on the light emitting direction of the display panel201and using phase delay of different regions on the phase difference plate202such that lights of different pixels emit by different polarization directions. Therefore, the viewer wearing a polarized glasses204can observe a 3D image.

However, due to the image crosstalk between the signals of left and right eye, the 3D display technology using phase difference plate exist the drawback of smaller vertical viewing angle.

Specifically, as shown inFIG. 2, the distance between the panel201and the phase difference plate202is h. The following uses three pixels in the display area of the display panel201for example. The black matrix214area is between odd-row pixels211,213and even-row pixel212. Letter a is the height of the pixel display area and letter b is the width of the black matrix214in the vertical direction, and letter c is the height of the phase delay fringes of the phase plate202, wherein, p=a+b, and p is a fixed value for the pixel size. The non-cross-talk display area203in the figure is the vertical viewing angle θ and satisfies the following relationship:

From the relationship formula 1, increasing the width b of the black matrix can increase the vertical viewing angle θ, but will reduce the height of a pixel display area, a, thereby reducing the aperture ratio of the display panel.

In summary, it is necessary to provide a display panel and a 3D display device for solving the problem of existing technology that is increasing the width of the shading layer (BM) to increase the vertical viewing angle, but reducing the aperture ratio.

Specifically, as shown inFIG. 9,FIG. 9is a schematic drawing of the first substrate of display panel inFIG. 8. In the way of implementation, a RGB pixel unit on the first substrate of the display panel91is used for an example. As shown inFIG. 9, a RGB pixel unit91on the first substrate includes: a data line915; multiple scan lines,911,912, and913; and a first sub-pixel unit901, a second sub-pixel unit902, and a third pixel unit903.

In this embodiment, the data lines915and a data line916are disposed parallel and alternatively, and the scan lines,911,912, and913are disposed along the direction perpendicular to the data line915.
