Problems solved by technology

[0003] However, as the size of the display panel PL increases and its resolution improves, the timing control circuit TCON is coupled to the traces of the source driving circuits SD1 - SDN due to the positional differences between the source driving circuits SD1 - SDN . The length of the line is different, and the channel loss (Channel loss) generated by it will become non-negligible
Especially when the timing control circuit TCON outputs timing control signals to the source driving circuits SD1~SDN, it is very likely that the source driving circuits SD1~SDN will receive errors due to channel loss, which needs to be improved urgently.

Abstract

The invention discloses a method for automatically selecting equalizer gears, which is applied to a display device. The display device comprises a display panel, a plurality of source electrode driving circuits and a time sequence control circuit. The plurality of source driving circuits respectively comprise a plurality of equalizers. The method comprises the following steps of: coupling a time sequence control circuit with the plurality of source electrode driving circuits and coupling the plurality of source electrode driving circuits with the display panel; and the time sequence control circuit and the plurality of source electrode driving circuits communicate the training results of the plurality of equalizers through at least one bidirectional control signal so as to realize display data transmission synchronization.

Description

technical field [0001] The present invention relates to a display device, in particular to a method for automatically selecting an equalizer gear position applied to the display device. Background technique [0002] Generally speaking, if figure 1 As shown, the display device 1 includes a display panel PL, source driving circuits SD1 to SDN, and a timing control circuit TCON. The timing control circuit TCON is respectively coupled to the source driving circuits SD1 ˜SDN through wires. The source driving circuits SD1 ˜SDN are respectively coupled to different display regions of the display panel PL. [0003] However, as the size of the display panel PL increases and its resolution increases, due to the positional difference between the source driving circuits SD1-SDN, the timing control circuit TCON is coupled to the source driving circuits SD1-SDN. The length of the line is different, and the channel loss (Channel loss) it produces will become non-negligible. Especially ...
