Problems solved by technology

[0004] The shortcomings of this design are: in 3D mode, the user must wear the corresponding 3D switch eyes to receive the 3D image. The result of viewing with the naked eye is just the superposition of the left and right eye views, which will cause ghosting, blurring, and blurring to the user. ghosting
Therefore, users must wear 3D switch glasses to watch, and at this time, 2D images cannot be viewed on the screen, which will affect the comfort and effect of viewing

Embodiment Construction

[0049] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] The embodiment improves the existing 3-D display technology based on time-domain psychovisual modulation display, so that the stereoscopic display technology can be backward compatible, and can wear 3-D switching glasses to watch 3-D stereoscopic display, and at the same time It can also provide clear picture quality for users who watch 2-D pictures with naked eyes.

[0051] The embodiment provides a backward compatible stereoscopic display solution which is Temporal Psychovisual Modulation (TPVM, TemporalPsychovisualModulation) display. As a cutting-edge technology, time domain psychovisual modulation display enhances the function of optoelectronic display through signal processing technology. At the same time, it can also make up for the shortcomings of the traditional time-series-based 3-D display technology, and can provide a clea...

Abstract

The invention provides a high fidelity three-dimensional display method compatible with two-dimensional display based on LED backlight modulation. A linear least square problem is obtained for a calculation error by establishing a backward compensation module of time domain psychological visual modulation display; a backlight intensity coefficient is introduced, and an optimization problem is obtained through the linear least square problem; the optimization problem is simplified and converted into a geological problem to be solved, and an optimal and improved scheme of the time domain psychological visual modulation display is obtained. The existing 3-D technology is improved, so that the three-dimensional display technology can be compatible backwards, a user can see the three-dimensional display with switch glasses, and meanwhile a 2-D image can be clearly provided without wearing the glasses. According to the scheme of the high fidelity three-dimensional display method compatible with two-dimensional display based on LED backlight modulation, power consumption is low, complexity is low, a 3-D image with high quality is provided with priority, and meanwhile the quality of the 2-D image can be ensured.

Description

technical field [0001] The invention relates to a high-fidelity three-dimensional display method compatible with two-dimensional display based on LED backlight modulation. Background technique [0002] The technology commonly used in 3DTV or display imaging in the market today is time-multiplexed stereoscopic display, that is, by rapidly switching the left and right eye views on a screen in a time sequence, at the same time, the observer wears synchronous 3D switching glasses and receives the expected One eye's view and the other eye's view are turned off, resulting in a superimposed stereoscopic view effect. [0003] The advantage of this design is that it is low cost and easy to implement. It only needs a display screen with a refresh rate higher than 120Hz and 3D switching eyes to realize stereoscopic imaging. And compared with the autostereoscopic imaging technology, the instantaneous multiplexing technology adopted by the time-multiplexed 3D display has lower channel c...
