Abstract

The invention provides a source driver and a display and belongs to the technical field of display. The source driver is applied to the display and comprises a control circuit, wherein the control circuit is provided with group switches. When receiving wrong data signals, the control circuit is used for cutting off the data signals; when receiving correct data signals, the control circuit turns on the group switches and transmits the correct data signals. Through the source driver and the display, the panel detection process can be simplified, the time for adjusting the display to stop the display from outputting wrong frames is shortened, and meanwhile the problem about panel installation can be detected.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a source driver and a display. Background technique [0002] The TFT-LCD drive architecture is mainly composed of source (Source), gate (Gate) driver and timing controller (TCON), where the source (Source) driver is responsible for receiving signals from the timing controller (TCON) , the received image data is converted into a voltage by the internal circuit of the source drive driver and output to the panel. Similarly, the gate drive driver also needs to receive the control signal sent by the timing controller (TCON), through which the voltage required to turn on or off the TFT in the panel is generated at an appropriate time point, when the output When the voltage is high, the TFT inside the panel can be turned on. At this time, the voltage output by the source (Source) driver will charge the TFT pixel. When the gate (Gate) drive driver outputs a low voltage, the TFT inside...
