Embodiment Construction

[0022] The display device and its control method proposed by the present invention are described in detail as follows with reference to the drawings and embodiments.

[0023] The display device of the present invention divides one frame time (1H) into equal upper half frame time (marked as 1 / 2H) and lower half frame time (marked as 2 / 2H) for display, and uses the phase modulation panel (active retarder) to achieve 3D display by retarding the phase of the light transmitted through the display image. For the same display area within one frame time, 1 / 2H displays the image for the left eye, and 2 / 2H displays the image for the right eye (the left and right eye images can be switched), so as to ensure that the resolution of the 3D image will not be halved within one frame time. Rate and field frequency will not be reduced (compared to 2D display).

[0024] As shown in FIGS. 1( a )- 1 ( b ), a display device according to an embodiment of the present invention includes: a backlight ...

Abstract

The invention discloses a display device and a control method of the display device, which relate to the technical field of 2D/3D (2 Dimensional/3 Dimensional) display. The device comprises a display panel and a phase modulation panel, wherein the display panel is used for displaying a 2D image in a 2D display mode, displaying a left eye image or a right eye image in a 3D display mode in the time of a first half frame of a frame and displaying the right eye image or the left eye image in the time of a second half frame; the phase modulation panel is arranged between the display panel and human eyes, and linearly polarized light transmitted by the display panel in the 2D mode is emitted out in a way of maintaining the polarization direction; and in the 3D display mode, according to the attributes of the image displayed by the display panel, the linearly polarized light transmitted by the display panel is subjected to phase modulation, and modulated light is transmitted. According to the display device, 2D/3D display without reducing the vertical resolution and the field frequency is carried out through the display panel adopting a pixel design with double grid lines and double data lines by combining the phase modulation panel which can be driven according to the attributes of the displayed images.

Description

technical field [0001] The present invention relates to the technical field of 2D / 3D display, in particular to a 2D / 3D display device with full field frequency and full resolution and a control method thereof. Background technique [0002] With the development of display technology and the improvement of people's pursuit of senses, 3D display technology has attracted widespread attention. 3D stereoscopic display is a major development trend in the display field in the future, and glasses-type 3D liquid crystal display technology is a more commonly used one. Two left and right images are projected by the display, and the user uses glasses matched with the display to distribute the left and right images to the left and right eyes respectively. Glasses-type 3D display is easy to implement and has good stereo effect, and is currently the mainstream product of 3D display. [0003] Glasses-based 3D display technologies mainly include shutter glass and pattern retarder, both of w...
