Problems solved by technology

At present, 3D technology does not improve the image quality much, especially the deepest interference (cross-talk) problem that affects binocular vision has not proposed an effective solution
[0007] However, the above-mentioned technique has the disadvantage of greatly reducing the strength of monocular image contrast

Embodiment Construction

[0048] The present invention utilizes the duty cycle of directly controlling the luminous intensity of the light source module to reduce the appearance of interference phenomenon. In other words, the light source module does not emit light continuously, but periodically emits light according to a set duty cycle of light emission. Some examples are given below as descriptions of the present invention, but the present invention is not limited to the examples given.

[0049] First, let’s look at the problem of traditional interference again. Fig. 3 shows a schematic diagram of the reason why the present invention considers the interference problem caused by the traditional technology. In FIG. 3 , the signal 132 on the time axis is, for example, the gray values ​​of pixels alternately displayed in the left-eye image, while the right-eye image ideally has no content. The signal 130 is a grayscale voltage signal corresponding to the left eye and the right eye on the time axis. In...

Abstract

This device consists of a photo source module (PS) and a picture display component (PD). PS possesses at least a radiation block (RB). A photo source driving unit (PSD) connects PS and PD. Driving by PSD, RB irradiates synchronously a light according to the PD display frequency but a small bright/ dark ratio. The photo source synchronization with PD can reduce the interfere upon the 3D pictures.

Description

technical field [0001] The invention relates to a stereoscopic image display technology, and in particular to a stereoscopic image display device and a method for reducing interference of stereoscopic images. Background technique [0002] The display method of stereoscopic (3D) images has entered the stage of commercialization along with the vigorous development of displays. The 3D display device is bound to become an important development direction of the next generation display, and this has been a consensus in the industry. More and more markets, such as medicine, display, entertainment, education, military, design, advertising, etc., all require naked-eye 3D display technology. [0003] However, the gradual popularization of 3D display technology still encounters various obstacles. Among them, the biggest obstacle is still the limitation of the display technology itself. One of the most important bottlenecks in the commercialization of 3D displays at present is that t...
