Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provides a kind of anti-interference and do not have a TV with 3 D stereo function of time-delay.
For achieving the above object, the utility model adopts following technical scheme:
TV with 3 D stereo function; This TV comprises display screen, mainboard and 3D glasses in addition; Said mainboard has interface module, main control module and gating switch module; Main control module connection interface module and logical switch module, a logical switch module connection interface module and an infrared synchronizing signal emission box, infrared synchronizing signal emission box sends the glasses switching pulse signal according to simulated sync pulse to the 3D glasses; Said interface module connects display screen.
Said logical switch module comprises gating switch chip, touch-switch and resistance R 3; Said gating switch chip comprises the first input end that is used to receive said screen control signal; Be used to receive second input of said simulated sync pulse; The control end of said gating switch chip is connected with an end of said touch-switch and an end of said resistance R 3 respectively; The other end of said resistance R 3 is connected with 5V voltage, and the other end of said touch-switch is connected with ground, and the output of said gating switch chip is connected and is used to export said screen control signal or said simulated sync pulse with said infrared synchronizing signal emission box.
The utility model is because the 3D glasses are main control modules from the infrared synchronizing signal emission glasses switching pulse signal that box received generates according to the change frequency of frame of video; So compare the screen control signal; Can not produce time-delay; And anti-interference stronger, make the considerable 3D TV of seeing better effects if of user.
Description of drawings:
Accompanying drawing 1 is the building-block of logic of the preferred embodiment of the utility model;
Accompanying drawing 2 is circuit diagrams of the gating switch module one of which embodiment of the utility model.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated:
Consult Fig. 1, shown in 2; The TV that provides at the utility model with 3 D stereo function; This TV comprises display screen 1, mainboard 2 and 3D glasses (not shown) in addition; Said mainboard 2 has interface module 21, main control module 22 and gating switch module 23; Main control module 22 connection interface module 21 and logical switch module 23, logical switch module 23 connection interface module 21 and an infrared synchronizing signal emission box 3, infrared synchronizing signal emission box 3 sends the glasses switching pulse signal according to simulated sync pulse to the 3D glasses; Said interface module 21 is the LVDS interface, connects display screen.Main control module 22 generates simulated sync pulse through interface module 21 to display screen 1 output video frame and according to the change frequency of the frame of video of being exported, and infrared synchronizing signal emission box 3 sends the glasses switching pulse signal according to this simulated sync pulse to the 3D glasses.Logical switch module 23 is used for gating screen control signal or simulated sync pulse; And will shield control signal or simulated sync pulse and export infrared synchronizing signal emission box 3 to; Through comparing the stereoscopic TV effect of being watched under two kinds of situation, to judge whether the screen control signal occurs delaying time or being interfered.
Shown in Figure 2; Said logical switch module 23 comprises gating switch chip U1, touch-switch SW, resistance R 1, resistance R 2, resistance R 3, resistance R 4, capacitor C 1 and capacitor C 2; Gating switch chip U1 specifically comprises first input end A, the second input B, control end C, output X, power end VCC and earth terminal GND; Wherein, the power end of gating switch chip U1 is connected with 5V voltage; The end of the screen control signal input resistance R1 of display screen 1 output, the other end of resistance R 1 is connected with the first input end A of gating switch chip U1; One end of resistance R 2 is connected with the second input B of gating switch chip U1, and the other end of resistance R 2 is connected with main control module 22; One end of resistance R 3 is connected with 5V voltage, and the other end of resistance R 3 is connected with the end of touch-switch SW and the control end X of gating switch chip U1 respectively, and the other end of touch-switch SW is connected with ground; One end of resistance R 4 is connected with the output X of gating switch chip U1, and the other end of resistance R 4 is connected with the input 3D_SYNC of infrared synchronizing signal emission box; One end of capacitor C 1 is connected with the power end of gating switch chip U1, and the other end of capacitor C 1 is connected with ground; One end of capacitor C 2 is connected with the power end of gating switch chip U1, and the other end of capacitor C 2 is connected with ground.During work; Suppose when the level of the control end C of gating switch chip U1 when being high; The first input end A of gating switch chip U1 receives the screen control signal of display screen output, the output cutout screen control signal of gating switch chip U1, when the level of the control end C of gating switch chip U1 when low; The second input B of gating switch chip U1 receives the simulated sync pulse of main control module output, the output output simulated sync pulse of gating switch chip U1.When if touch-switch SW opens; The level of the control end C of gating switch chip U1 is high; At this moment input signal is screen control signal 3D_SYNC, and 1 pair of screen control signal that is received of resistance R this moment plays metering function, the corresponding screen control signal of gating switch chip U1 output; 4 pairs of screen control signals of being exported of resistance R this moment play metering function, and infrared then synchronizing signal emission box will send to the 3D glasses according to this glasses switching pulse signal that shields the control signal generation; When if touch-switch SW is closed; The level of the control end of gating switch chip U1 is low; At this moment input signal is simulated sync pulse 3D_SYNC; 2 pairs of simulated sync pulse that received of resistance R this moment play metering function; Gating switch chip U1 output corresponding simulating synchronization pulse, 4 pairs of simulated sync pulse of being exported of resistance R this moment play metering function, and infrared then synchronizing signal emission box will send to the 3D glasses according to the glasses switching pulse signal that this simulated sync pulse produces.
