Referring to Fig. 4, be the schematic flow sheet of an embodiment of control method of the launch-box of spatical television set provided by the invention.
The control method of the launch-box of the spatical television set that present embodiment provides, described spatical television set comprises display screen, TV motherboard, launch-box and anaglyph spectacles, and is connected by communication signal line, data signal line and synchronous signal line between TV motherboard and the launch-box; Then described control method specifically may further comprise the steps:
S1, TV motherboard read the state information of launch-box by the communication signal line, judge according to described state information whether launch-box successfully discerns the display screen performance data that TV motherboard sends;
S2, TV motherboard constantly send the display screen performance data by data-signal alignment launch-box when judging that launch-box is not successfully discerned the display screen performance data; Wherein, different display screen performance data is used to identify the display screen of different qualities.
S3, launch-box read corresponding screen response delay data according to the display screen performance data that TV motherboard sends from data storage cell; Wherein, described data storage cell stores the screen response delay data of the display screen of multiple different qualities, and each screen response delay data all shines upon one by one with the display screen of corresponding a certain characteristic;
In addition, if launch-box successfully reads screen response delay data, also send the state information of successfully discerning the display screen performance data, otherwise send the state information of successfully not discerning the display screen performance data by the described TV motherboard of described communication signal alignment;
S4, TV motherboard send synchronizing signal by synchronizing signal alignment launch-box; Wherein, described synchronizing signal is used to control the working method of the left and right sides eyeglass of described anaglyph spectacles;
S5, launch-box receive the synchronizing signal that TV motherboard sends, and according to the time-delay of the screen response delay data adjustment synchronizing signal that is read, and the synchronizing signal after will handling is sent to described anaglyph spectacles; Thereby the opening time of control anaglyph spectacles.Preferably, launch-box is sent to anaglyph spectacles with infrared ray or the bluetooth approach synchronizing signal of adjusting of will delaying time.
Preferably, the state information that launch-box is successfully discerned the display screen performance data is the low level id signal, and the state information that launch-box is not successfully discerned the display screen performance data is the high level id signal.When TV motherboard reads the high level id signal by the communication signal line, constantly send the display screen performance data by data-signal alignment launch-box; When TV motherboard reads the low level id signal by the communication signal line, stop to send the display screen performance data to launch-box.
The control method of the launch-box of the spatical television set that for example embodiment of the invention is provided is described in detail below.Launch-box is connected by MINI USB terminal shown in Figure 1 with TV motherboard.
During concrete enforcement, the PIN2 terminal (TXD) of launch-box is defaulted as high level; When launch-box is connected with TV motherboard, after TV motherboard detects the PIN2 terminal and is high level, send the display screen performance data to launch-box by PIN3 terminal (RXD).Wherein, the display screen of different qualities has different screen response time-delays, and present embodiment adopts different display screen performance datas to identify the display screen of different qualities.
Launch-box receives the display screen performance data that TV motherboard sends, and reads corresponding screen response delay data from data storage cell; If the display screen performance data that sends according to TV motherboard can't read correct screen response delay data, then the PIN2 terminal keeps high level; Up to reading correct screen response delay data, the PIN2 terminal becomes low level.After TV motherboard detects the PIN2 terminal and becomes low level, no longer send the display screen performance data, the communication cancellation to launch-box.
TV motherboard sends synchronizing signal by PIN4 terminal (SYNC) to launch-box, launch-box responds the time-delay that delay data is adjusted anaglyph spectacles opening time and synchronizing signal according to the screen that is read, and in the mode of infrared ray or bluetooth synchronizing signal is sent to anaglyph spectacles.
The spatical television set that the embodiment of the invention provides and the control method of launch-box thereof, two communication lines of addition communication signal line and data signal line between TV motherboard and launch-box, TV motherboard detects launch-box by the communication signal line and whether successfully discerns display screen, and by data signal line the display screen performance data is sent to launch-box.And the screen of having stored the display screen of multiple different qualities on the launch-box responds delay data, can respond delay data according to the screen that the display screen performance data that TV motherboard sends is selected to be complementary, be used to adjust the time-delay of anaglyph spectacles opening time and relative field sync signal, thereby reach best stereo display effect.The embodiment of the invention can the dynamic adjustments spatical television set the relevant parameter of launch-box, make launch-box can mate the display screen of different response times, thereby improve the compatibility of launch-box the display screen of different qualities.
The above is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
