Abstract
Disclosed is a demultiplex type display driving circuit, applied in a RGBW four colors pixel structure display device, comprising a plurality of driving units, and each driving unit comprises eight demultiplex modules, and each demultiplex module comprises three thin film transistors, and gates of the three thin film transistors are electrically coupled to a first branch control signal (Demux), a second branch control signal (Demux), and a third branch control signal (Demux) respectively, and source are electrically coupled to the same data signal, and drains are electrically coupled to one data line in a jump manner, respectively. Thus, the pulse duration of each branch control signal is equal to ⅓ of a pulse duration of the scan signal to increase the charging time of the data signal and promote the charging rate of the sub pixel under circumstance that the pulse duration of the scan signal is not changed.
