摘要（英）：

A liquid crystal panel driving circuit, comprising an input end (VIN), a first resistor (R1), a second resistor (R2), a comparator (A), a light emitting diode (D), a latch (1), an RC circuit (2), and a power voltage (VDD). The input end (VIN) is connected to a ground end by means of the first resistor (R1) and the second resistor (R2) sequentially connected in series. A positive input end of the comparator (A) is connected to a reference voltage (Vref1), and a negative input end of the capacitor is connected between the first resistor (R1) and the second resistor (R2). The positive electrode of the light emitting diode (D) is connected to the output of the comparator (A), and the negative electrode of the light emitting diode (D) is connected to the latch (1). The input and output of the RC circuit (2) are connected to the power voltage (VDD) and the latch (1), respectively. The liquid crystal panel driving circuit has good reliability and excellent user experience.
