[0061] Please refer to figure 1 and Figure 4 Embodiments of the present invention one as:
[0062] Three-dimensional imaging method, in the present technology, there is an active glasses and passive, in view of the present invention relates to an active glasses, then the stereoscopic imaging technique of the active glasses will be described below, and the principles are shown in the foregoing background technique. Because this technique is alternately displayed on the screen, this display requires a higher refresh frequency, such as a display of 120 Hz, such as a display of 120 Hz, such as a display of around 60 Hz Screen, because the residual effect of the LCD is updated on the display. image 3 As shown, there is a different backlight control mode at 120 Hz refresh frequencies, specifically a local control backlight and an increase of 30% -40% vtotal (vertical synchronization cycle), and this backlight must also satisfy the frequency of such switching. Lightbar's current requirements.
[0063] Such as figure 1 and Figure 4 As shown, the present embodiment is mainly to implement a screen switching signal and a lens switching signal synchronous output at a high refresh rate screen of 240 Hz, and specifically includes the steps:
[0064] S1, screen switching according to the signal order of 240 Hz and the signal order of the LLRR, L represents the left eye screen, and R represents the right eye screen;
[0065] In the present embodiment, the signal sequence of the LLRR refers to the signal order of the intermediate continuously, which turns into LLRRLLRRLLRRRRRRRRRR ... for the whole, thereby the signal order of the LRRL, RRLL, and RLLR, is equivalent to the signal order of LLRR. It is essentially in the signal order of LLRR;
[0066] S2, turn off the backlight at the first L and the first R, and open the backlight at the second L and the second R;
[0067] In the present embodiment, the backlight is turned off at the first L and the first R, and the backlight is opened when the second L and the second R are opened, since the left eye screen to the right eye picture and from the right The next picture when the eye screen is switched to the left eye, which is closed, thereby avoiding the image of the right eye or the right eye to see the left eye.
[0068] S3, synchronous output Only the left eye is opened when two L is opened and only the lens switch signal to 3D glasses of the right eye is opened when two R is turned to achieve stereoscopic imaging.
[0069] In the present embodiment, only the left eye is opened only when two L is opened and only the lens switching signal of only the right eye is turned on, that is, the left-right lens is only switched once, then the left-right lens is only switched once. The corresponding 240 Hz screen displays only 60 Hz switching frequencies, thereby adapted to 60 Hz 3D glasses.
[0070] In the present embodiment, the 3D glasses in step S3 include a wireless charging module such that the active shutter 3D glasses support wireless charging.
[0071] In the present embodiment, the synchronization output in step S3 specifically includes the steps of:
[0072] The synchronization signal is sent to the PIN pin by inputting an output interface. The synchronization signal is rotated to the USB interface through the PIN pin, and the USB interface is used to connect the 3D glasses to lead the synchronization signal to the signal generator of the 3D glasses, thereby implementing a synchronous output switching screen. Signal and lens switching signals to achieve a better three-dimensional imaging.
[0073] Among them, the steps are also included:
[0074] Receive 2 / 3D switching signals, implement 2 / 3D switching by calling the 3D Vision driver built into the control board to support the drive-free running, so that it is no longer limited to a graphics card and the corresponding 3D Vision driver can pass through one Press one button to switch 2/3D to support all the ways of integrated graphics, A cards, and N cards.
[0075] In this embodiment, the steps are also included:
[0076] The receiving screen rotation signal, acquires the preset angle in the screen rotation signal, and rotates the preset angle in the center position of the display at the center position of the display or counterclockwise. Among them, the preset angle includes 90 °, 180 ° or 270 °.
