Detailed Description
In order to make the technical solutions in the embodiments of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application are further described in detail below with reference to the accompanying drawings.
As shown in fig. 2, a schematic structural diagram of a liquid crystal television circuit system provided in an embodiment of the present application, referring to fig. 2, the liquid crystal television circuit system includes: TCON panel 1, first lcd panel S2 and second lcd panel S3. The TCON board is provided with a signal output device 4, and the signal output device 4 comprises a TCON chip and a power management unit chip. A first signal flat cable 5 is arranged between the first liquid crystal screen S plate 2 and the TCON plate 1, and a second signal flat cable 6 is arranged between the second liquid crystal screen S plate 3 and the TCON plate 1. When the signal output device 4 is a TCON chip, the signal output device 4 outputs a television image signal for display on the first liquid crystal panel S2 and the second liquid crystal panel S3. If the signal output device 4 is a power management unit chip, the signal output device 4 outputs a power voltage signal for supplying a voltage signal to the first liquid crystal panel S2 and the second liquid crystal panel S3. In this embodiment, the signal output end of the signal output device 4 does not output signals through the first signal cable 5 and the second signal cable 6, but an additional signal line is provided as an intermediate transmission medium for signals.
Specifically, as shown in fig. 3, a first signal line 7 and a second signal line 8 are provided between the TCON board 1 and the first liquid crystal panel S board 2. The first signal line 7 and the second signal line 8 are respectively disposed at two side edges of the first signal flat cable 5. Accordingly, a third signal line 9 and a fourth signal line 10 are provided between the TCON board 1 and the second liquid crystal panel S3, and the third signal line 9 and the fourth signal line 10 are respectively provided at both side edge positions of the second signal flat cable 6.
The first end of the first signal line 7 is electrically connected with the signal output end of the TCON board 1, specifically, the first end of the first signal line 7 is connected with the signal output end of the signal output device 4 arranged on the TCON board 1, the second end of the first signal line 7 is connected with the first liquid crystal screen S board 2, and the two ends of the second signal line 8 are respectively connected with the TCON board 1 and the first liquid crystal screen S board 2. The two ends of the third signal line 9 are respectively connected with the two ends of the TCON board 1 and the second liquid crystal screen S board 3, the first end of the fourth signal line 10 is connected with the second liquid crystal screen S board 3, and the second end of the fourth signal line 10 is connected to a flat cable signal input end on the TCON board 1.
When the first signal flat cable 5 and the second signal flat cable 6 are plugged correctly, the first end of the first signal line 7 is electrically connected with the signal output end of the signal output device 4, the two ends of the second signal line 8 are respectively electrically connected with the second end of the first signal line 7 and the first end of the third signal line 9, the second end of the third signal line 9 is electrically connected with the first end of the fourth signal line 10, and the second end of the fourth signal line 10 is respectively electrically connected with the signal input end of the first signal flat cable 5 and the signal input end of the second signal flat cable 6.
The first liquid crystal screen S plate 2 in the liquid crystal television circuit system provided by the embodiment of the application is provided with the fifth signal line 11, and the fifth signal line 11 is arranged at the flat cable socket position of the first liquid crystal screen S plate 2 and is parallel to the opening direction of the socket. The TCON board 1 is provided with a sixth signal line 12, and two ends of the sixth signal line 12 are respectively connected to two adjacent ends of the two flat cable sockets on the TCON board 1. A seventh signal line 13 is arranged in the second liquid crystal panel S3, and the seventh signal line 13 is arranged at the position of the flat cable socket of the second liquid crystal panel S3 and is parallel to the opening direction of the socket.
If the first signal flat cable 5 and the second signal flat cable 6 are plugged correctly, two ends of the fifth signal line 11 are electrically connected with the second end of the first signal line 7 and the first end of the second signal line 8 respectively. Both ends of the sixth signal line 12 are electrically connected to the second end of the second signal line and the first end of the third signal line, respectively. Both ends of the seventh signal line 13 are electrically connected to the second end of the third signal line and the first end of the fourth signal line, respectively. A signal loop is formed: the signal output device 4 → the first signal line 7 → the fifth signal line 11 → the second signal line 8 → the sixth signal line 12 → the third signal line 9 → the seventh signal line 13 → the fourth signal line 10. If any signal flat cable is not plugged well in the plugging process of the signal flat cables, the circuit is interrupted.
Taking the signal loop as an example, if the side of the first signal flat cable 5 close to the first signal line 7 is not well plugged, there may be two cases. As shown in fig. 4, one is poor plugging on one side of the TCON board 1, which directly results in that the first end of the first signal 7 cannot be connected to the signal output end of the signal output device 4, and no signal is input into the signal loop.
As shown in fig. 5, if the first liquid crystal panel S2 is not plugged well, the signal input of the first end of the first signal line 7 is normal, but the second end of the first signal line 7 is disconnected from the first end of the fifth signal line 11 at the side of the first liquid crystal panel S2. At this time, although there is a signal input in the signal loop, there is no signal input from the fifth signal line 11, so that finally, no signal input is received by the first liquid crystal panel S2 or the second liquid crystal panel S3. At this time, the condition that the signal flat cable is not plugged well can be judged, and manual checking is only needed.
When the first signal flat cable 5 and the second signal flat cable 6 are correctly inserted, the first signal flat cable 5 and the second signal flat cable 6 are parallel to each other. The first signal line 7 and the second signal line 8 are arranged at the edge positions of two sides of the first signal flat cable 5, and the third signal line 9 and the fourth signal line 10 are arranged at the edge positions of two sides of the second signal flat cable 6. When the first signal flat cable 5 and the second signal flat cable 6 are correctly inserted, the first signal line 7, the second signal line 8, the third signal line 9 and the fourth signal line 10 are arranged in parallel. In addition, no matter the TCON board 1 or the signal flat cable socket of any liquid crystal television S board is in a specific specification shape, when the two ends of the first signal flat cable 5 are correctly inserted, the first signal line 7 and the second signal line 8 are perpendicular to the fifth signal line 11 and the sixth signal line 12. Similarly, the third signal line 9 and the fourth signal line 10 are perpendicular to the sixth signal line 12 and the seventh signal line 13. As can be seen from the above, the fifth signal line 11, the sixth signal line 12, and the seventh signal line 13 are also provided in parallel.
Alternatively, the signal output terminal of the signal output device 4 is connected to the first terminal of the eighth signal line 14, and the second terminal of the eighth signal line 14 is connected to the first terminal of the first signal line 7. Only when the first signal flat cable 5 is accurately inserted corresponding to one side of the TCON board 1, the first end of the first signal line 7 can be electrically connected with the second end of the eighth signal line 14, and the signal output by the signal output device 4 can be received. As shown in fig. 6, if the first signal cable 5 is not accurately plugged to the TCON board 1 side in the above situation, the first signal line 7 cannot be accurately connected to the eighth signal line 14, and thus cannot receive the signal output by the signal output device 4.
The TCON board 1 in this embodiment is also provided with a ninth signal line 15 and a tenth signal line 16. When the second signal flat cable 6 is accurately inserted corresponding to one side of the TCON board 1, the second end of the fourth signal line 10 is electrically connected to the first end of the ninth signal line 15. A second end of the ninth signal line 15 is electrically connected to a signal input terminal of the second signal flat cable 6 and a first end of the tenth signal line 16, respectively, and a second end of the tenth signal line 16 is electrically connected to a signal input terminal of the first signal flat cable 5. In the above embodiment, only when the second signal flat cable 6 is accurately inserted into the TCON board 1, the first end of the fourth signal flat cable 10 can be electrically connected to the first end of the ninth signal line 15, and at this time, the signal can be output through the second end of the ninth signal line 15 and respectively sent to the signal input end of the second signal flat cable 6 and the first end of the tenth signal line 16, and the signal output from the second end of the ninth signal line 15 is sent to the first signal flat cable 5 through the second end of the tenth signal line 16. As shown in fig. 7, if the second signal flat cable 6 is incorrectly inserted into the TCON board 1 corresponding to one side, the fourth signal line 10 cannot be correctly connected to the ninth signal line 15, and the signal from the signal output device 4 cannot be transmitted to the first signal flat cable 5 and the second signal flat cable 6.
In this embodiment, the first signal line 7 and the second signal line 8 may be signal lines on both sides of the first signal flat cable 5, and the third signal line 9 and the fourth signal line 10 may be signal lines on both sides of the second signal flat cable 6. If the signal lines in the first signal flat cable 5 and the second signal flat cable 6 are selected as the signal lines in the signal loop, the signal flat cables need to be subjected to preliminary processing in the early period, so that the signal lines as the first signal line 7, the second signal line 8, the third signal line 9 and the fourth signal line 10 are distinguished from other signal lines in the corresponding signal flat cables, and are not used as signal lines transmitted to the corresponding lcd tv S panel in the later period.
As can be seen from the foregoing embodiments, in the liquid crystal television circuit system provided in this embodiment, if the signal flat cable between the TCON board 1 and any one of the liquid crystal television S boards is not plugged correctly or is not plugged properly, the loop formed by the first signal line 7, the fifth signal line 11, the second signal line 8, the sixth signal line 12, the third signal line 9, the seventh signal line 13, and the fourth signal line 10 is interrupted and cannot be conducted, and then any one of the liquid crystal television S boards cannot receive the signal sent by the signal output device 4 in the TCON board 1. Only when the first signal flat cable 5 and the second signal flat cable 6 are correctly inserted, the loop can be completely conducted, and signals are normally output to the first liquid crystal screen S plate 2 and the second liquid crystal screen S plate 3, so that the problem that the liquid crystal television cannot normally display due to poor signal flat cable insertion in a liquid crystal television circuit system is solved.
The application also provides an embodiment of the liquid crystal display television. The liquid crystal television provided by the embodiment of the application can comprise: a liquid crystal screen 101 and a liquid crystal television circuit system 102.

In this embodiment, a first signal line, a second signal line, a third signal line, a fourth signal line, a fifth signal line, a sixth signal line, and a seventh signal line are further disposed between the TCON board and the first liquid crystal display S board and the second liquid crystal display S board, the signal lines form a signal loop, a signal input end of the signal loop is connected to a signal output end of a signal output device on the TCON board, and a signal output end of the signal loop is connected to signal input ends of the first signal flat cable and the second signal flat cable. If any one of the first signal flat cable and the second signal flat cable has poor plug wire, the signal loop is interrupted, and the first liquid crystal television S plate and the second liquid crystal television S plate cannot receive any signal.
