Embodiment 1

[0026] This embodiment provides a 3D image signal processing method, such as figure 1 As shown, the method includes:

[0027] 101. A 3D display device processes a 3D image signal to generate a first synchronization control signal, where a frequency of the first synchronization control signal is 100 Hz.

[0028] Such as figure 2 As shown, it is a schematic diagram of the control relationship between the 3D TV set and the 3D glasses provided by the embodiment of the present invention, wherein the 3D glasses control signal generator located in the 3D TV set generates the first synchronous control signal in the form of infrared, and the infrared emitting module transmits the The first synchronous control signal is sent to the 3D glasses through an infrared receiving module inside the 3D glasses.

[0029] Such as image 3 As shown, it is the existing 120Hz synchronous control signal for 3D glasses. Among them, IR is the synchronous control signal for 3D glasses. Every time an i...

Embodiment 2

[0042] This embodiment provides a 3D display system, such as Figure 5 As shown, the system includes a 3D display device 51 and 3D glasses 52, wherein,

[0043]The 3D display device 51 is configured to generate a first synchronous control signal after processing the 3D image signal, and send the first synchronous control signal to the 3D glasses 52;

[0044] The 3D glasses 52 are used to control the opening or closing of the lenses of the 3D glasses according to the first synchronous control signal;

[0045] The frequency of the first synchronous control signal is 100 Hz.

[0046] Wherein, the 3D glasses 52 are further configured to generate a second synchronous control signal according to the first synchronous control signal for controlling opening or closing of lenses of the 3D glasses.

[0047] Further, the 3D glasses 52 are specifically configured to generate a second synchronous control signal according to the first synchronous control signal, for controlling the openin...

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a 3D image signal processing method and a 3D display system. Background technique [0002] With the advancement of information technology, 3D TV is becoming more and more popular. At present, 3D display technology can be divided into two categories: glasses-type and naked-eye-type. As a kind of glasses-type 3D technology, shutter-type 3D technology can maintain the original resolution of the picture, allowing users to easily enjoy the true full HD 3D effect. , and will not reduce the brightness of the screen, occupying the mainstream position in the market. Shutter-type 3D increases the screen refresh rate, and then divides a frame of image into two to form two groups of images corresponding to the left and right eyes for continuous interlaced display. Turn on the left lens and close the right lens when the picture is displayed, and turn on the right lens and close the left ...
