Abstract:
The present invention discloses a source electrode driving module for providing a data signal to an LCD unit, comprising: a Gamma correction chip and a source electrode driving chip, wherein, the Gamma correction chip comprises a P-GAMMA driving chip with three to eight output channels; the P-GAMMA driving chip is used for generating multiple control voltages providing to the source electrode driving chip; the source electrode driving chip comprises a first resistor string and a second resistor string; the multiple control voltages generated by the P-GAMMA driving chip connect into the first resistor string and the second resistor string according to turning points of a Gamma curve of the LCD unit, wherein, n is an integer, and 6≦n≦10. The present also disclose an LCD panel including the source electrode driving module described above.
