Ghost relieving circuit for display panel, display panel and ghost relieving method for display panel
The invention relates to a ghost relieving circuit for a display panel including a digital-to-analog converter, a first switching circuit, a second switching circuit, and a gamma chip. The gamma chip is connected to the digital-to-analog converter and configured to provide a plurality of reference voltages to the digital-to-analog converter. The digital-to-analog converter is individually connected to the first switching circuit and the second switching circuit, the first switching circuit is connected to receive a first working voltage and a positive-polarity reference voltage and has an positive-polarity data voltage output end, the second switching circuit is connected to receive a second working voltage and a negative-polarity reference voltage and has a negative-polarity data voltage output end, and the positive-polarity reference voltage is less than the negative-polarity reference voltage.
