TCON board, method for signal transmission from TCON board to SoC chip, and television

Abstract

The invention discloses a TCON board, a method for signal transmission from the TCON board to an SoC chip, and a television. The method for the signal transmission from the TCON board to the SoC chipthrough a single connection wire comprises the following steps: analyzing a video signal transmitted by the SoC chip to obtain video data; if the video data is normal, transmitting a first level signal to the SoC chip; if the video data is abnormal, searching a preset table for an abnormality code corresponding to abnormal information of the video data; generating an indication signal used for indicating the abnormality code according to a protocol between the TCON board and the SoC chip; and transmitting the indication signal to the SoC chip. Compared with the prior art, the TCON board, the method and the television provided by the invention have the advantages that under the precise that hardware structures are not changed, more effective information can be transmitted to the SoC chip through the single connection wire between the TCON board and the SoC chip, so that effective information interaction between the TCON board and the SoC chip can be guaranteed, and the system reliability can be improved.

Description

technical field [0001] The invention relates to the field of television, in particular to a TCON board and a method for transmitting signals to an SoC chip, and also to a television. Background technique [0002] serdes is the abbreviation of English SERializer (serializer) / DESerializer (deserializer). It is a mainstream time-division multiplexing and point-to-point serial communication technology, that is, multiple low-speed parallel signals at the sending end are converted into high-speed serial signals, passed through the transmission medium (optical cable or copper wire), and finally at the receiving end High-speed serial signals are reconverted to low-speed parallel signals. This point-to-point serial communication technology makes full use of the channel capacity of the transmission medium, reduces the number of required transmission channels and device pins, increases the transmission speed of signals, and thus greatly reduces communication costs.

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the state that the TCON board in the prior art can only feed back the normal or abnormal state of the video data to the SoC chip through a single connection line, and cannot feed back the specific abnormal information of the video data, thereby causing the SoC chip and the TCON board There is a defect of simplification in the information exchange between them, and a TCON board and a method for transmitting signals to the SoC chip, and a TV set are provided.
