Simple test method of liquid crystal response time based on photoelectric sensor

The invention discloses a simple test method of liquid crystal response time based on a photoelectric sensor. The method includes the steps that when a button is pressed, test equipment starts to work; a photoelectric sensor collects light emitted by an LCD, transforms the light into electric current and outputs the electric current; a resistor transforms the electric current outputted by the photoelectric sensor into voltage; an ADC converter transforms analog signals outputted by the photoelectric sensor into digital signals and outputs the digital signals to a microprocessor; the microprocessor processes the digital signals, calculates liquid crystal response time through algorithms, and displays the calculated liquid crystal response time on a displayer; after the test is completed, the button is pressed to stop the test. The simple test method of liquid crystal response time based on the photoelectric sensor has the advantages that the test is stable, cost is low, carrying is convenient, operation is eas
