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

A display device and a control method thereof. 2D / 3D display without reducing a vertical resolution and a field frequency is implemented by using a display panel (20) designed with double grid lines and double data lines and a phase modulation panel (30) driven according to an attribute of a displayed image. The device comprises: the display panel (20) and the phase modulation panel (30). The display panel (20) displays a 2D image in a 2D display mode; and in a 3D display mode, the display panel (20) displays a left-eye image or a right-eye image in the time of the first half frame of a frame and displays the right-eye image or the left-eye image in the time of the second half frame. The phase modulation panel (30) is arranged between the display panel (20) and human eyes, and keeps, in the 2D mode, linearly polarized light transmitted by the display panel (20) emitted in the polarization direction thereof; and in the 3D display mode, the phase modulation panel (30) performs, according to an attribute of an image displayed by the display panel (20), phase modulation on the linearly polarized light transmitted by the display panel (20), and transmits modulated light.

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...
