The reference voltage generating circuit includes a timing control circuit, a digital-to-analog conversion circuit, an operational amplifier circuit, a drive circuit, a switch control circuit, a first switch circuit, and a second switch circuit. The switch control circuit generates a control signal according to a frame start signal and a clock signal provided by the timing control circuit, and outputs the control signal to the first switch circuit and the second switch circuit to control the channels inside the first switch circuit and the second switch circuit to be turned on sequentially, such that an analog voltage signal output by the digital-to-analog conversion circuit can be output to the drive circuit through the first switch circuit, the operational amplifier circuit and the second switch circuit, to provide a reference voltage signal for the drive circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference voltage generating circuit and display device","description":"Disclosed are a reference voltage generating circuit and a display device.
