英文摘要：

In order to test the performance of light emitting and display devices, reduce human error and consider the influence of working temper ature on the electrical and optical properties, an optoelectronic performance testing system was designed and developed , which is for light emitting and display devices. The properties, such as brightness, temperature, voltage current and life, could be measured in the same software. This system consists of the power （GPD--3303）, the luminance meter （LS-110）, the temperature measuring module （temperature sensor and single chip computer ） and the measuring software. Based on LabVIEW, utilizing luminance meter LS-110, the brightness of the device is tested. By temperature sensor and single chip computer, the temperature of the device is tested. Controlled step output of the power by computer program, the actual output current and voltage data are read and then are sent to the computer. Real- time display of the testing process is shown in the software. The photoelectric properties of luminescent devices can be automatically measured and displayed at the same time. The testing system has the function of automatically saving data and image. It is very convenient and useful to test devices by this kind of computerized--experiment, Moreover it has advantages of high integrity, high accuracy, automatic extent, and strong operability.
