Problems solved by technology

At this time, considerable power consumption
Moreover, huge ripples will be caused at the power supply end and the ground end of the source driving circuit 110, resulting in a logical judgment error of the circuit, and even an error in the state of other control signals.

Abstract

The invention relates to a source electrode driving circuit applicable to a display panel. The source electrode driving circuit of the invention comprises a plurality of bolt locking devices and a plurality of output buffers. Each bolt locking device can receive a data signal and can output the data signal to corresponding output buffer in different time intervals according to a data output signal. When all the bolt locking devices transmit the data signal to corresponding output buffer, all the output buffers can synchronously transmit the data signal to the display panel.

Description

technical field [0001] The present invention relates to a source driving technology of a display panel, and in particular to a source driving technology of an asynchronously operated display panel. Background technique [0002] figure 1 It is a block diagram of a known source driving circuit. Please refer to figure 1 Generally speaking, the source driving circuit 110 is used to drive a display panel 140 . The known source driving circuit 110 includes a plurality of latches 112, 114...11n, which are respectively used to receive a plurality of data signals DS in sequence, and send the received data signals to corresponding output buffers in sequence 122, 124...12n. [0003] When the known source driving circuit 110 receives the data signal DS, it will be temporarily stored in the latches 112 , 114 . . . 11n in sequence. During the rising edge of a control signal LS, the latches 112, 114...11n will output data synchronously, so as to convert the potential of the data signa...
