The invention discloses a device for improving the performance of liquid crystal display equipment. A circuit of the device mainly comprises a current sampling device, a voltage difference detection circuit and a comparator. And the current sampling device is positioned between a common voltage circuit and a power supply input voltage circuit of the liquid crystal display panel. The voltage difference detection circuit is used for detecting the voltage difference between the two terminals of the current sampling device. And the comparator is used for comparing the voltage difference with the reference voltage. When the voltage difference of the current sampling device is higher than the reference voltage, the over-current signal is output to change the inversion method of the liquid crystal display panel, so that the performance of the system can be improved, and the stability of the system is improved. 本发明公开了一种改善液晶显示设备性能的装置，该装置电路主要包括电流采样装置，压差检测电路和比较器。所述的电流采样装置位于液晶显示面板的公共电压的电路和电源输入电压电路之间。所述的压差检测电路用来检测电流采样装置的两
