Abstract:
A method of burning-in and testing of field emission display devices comprising:loading at least one of the devices into an oven and operating the oven at an oven temperature in the range from approximately 20.degree. C. to approximately 125.degree. C.;applying an operation voltage to emitters of the at least one of the devices at said oven temperature;applying anode voltage to the at least one of the devices;applying grid voltage to the at least one of the devices;setting a video gain voltage at an initial low voltage value to cause substantially uniform luminance to occur for display pixels of said at least one display device;increasing the video gain voltage until a maximum voltage value is obtained; andmonitoring display performance parameters including luminance and anode current values during a burn-in period while operating the at least one of the display devices at said oven temperature.
