Problems solved by technology

[0003] However, due to the crosstalk between the left and right eye images in the stereoscopic display device of the prior art, the stereoscopic display device has the disadvantage of a small vertical viewing angle.
In the prior art, the vertical viewing angle of the stereoscopic display device can be increased by increasing the width of the black matrix (Black Matrix, BM), but this will lead to a decrease in the aperture ratio of the stereoscopic display device, affecting the overall display quality

Embodiment Construction

[0023] See figure 1 , figure 1 is a structural schematic diagram of the stereoscopic display device of the present invention, figure 2 It is a structural schematic diagram of the display panel in the stereoscopic display device of the present invention. Such as figure 1 As shown, the stereoscopic display device of the present invention includes a display panel 11 and a phase difference plate 12 .

[0024] In the present invention, the phase difference plate 12 is arranged on one side of the light emitting direction of the display panel 11 , and is arranged parallel to and spaced apart from the display panel 11 . It should be noted that the stereoscopic display device is suitable for viewers to wear glasses 13 having two lenses with orthogonal polarization directions.

[0025] Wherein, the display panel 11 may be a horizontal pixel structure or a vertical (Tri-gate) pixel structure. Wherein, in the horizontal pixel structure, sub-pixel units (sub-pixels) are arranged hori...

Abstract

The invention provides a three-dimensional display device and a drive method thereof. The three-dimensional display device comprises a plurality of pixel units arranged in a matrix mode, a gate driver and a source driver. A constant drive voltage is provided by the source driver to enable a fourth sub-pixel area to maintain a display of a dark state during the scanning process of the fourth sub-pixel area. By means of the method, the width of a black matrix is equivalently increased, and the vertical angle of view of the three-dimensional display device is increased under the condition that the aperture opening ratio is not reduced.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a stereoscopic display device and a driving method thereof. Background technique [0002] The stereoscopic display device in the prior art usually adopts parallel mode to realize stereoscopic display, and its basic working principle is to install a phase difference plate in the light emitting direction of the display panel, and use different regions of the phase difference plate to generate different phase delays, so that different The light from the pixels emerges in different polarization directions, allowing viewers wearing polarized glasses to observe stereoscopic images. [0003] However, due to the crosstalk between the left and right eye images in the stereoscopic display device in the prior art, the stereoscopic display device has the disadvantage of a small vertical viewing angle. In the prior art, the vertical viewing angle of the stereoscopic display device can be ...
