为方便对AM-OLED显示屏的各项性能进行测试,本文设计了基于labVIEW(Laboratory Virtual Instrument Engineering Workbench实验室虚拟仪器工程平台)的AM-OLED显示屏
V-I-L
曲线自动化测试系统,实现了在同一个软件下对显示屏的电压、电流、亮度、色坐标等特性的测试。首先,构建硬件电路即基于FPGA的AM-OLED显示屏驱动电路。接着,在此基础上利用labVIEW平台设计了AM-OLED显示屏
V-I-L
曲线测试系统的软件系统。最后,利用该系统对自主研发的基于MOTFT技术的12.2 cm(4.8 in)AM-OLED显示屏进行了测试,验证了系统的可靠性。通过对测试结果进行分析,AM-OLED显示屏达到设计亮度时各像素所需的数据电压约为9.2 V。总之,本系统实现了对显示屏性能参数的自动化测试,为显示屏的白平衡调节和AMOLED专用驱动芯片设计提供了数据支持,为显示屏的优化设计指明方向。
In order to test the performance of AM-OLED Display
an automatic
V-I-L
testing system based on virtual instrument technology was designed and used to acquire
V-I-L
curve. The perfor-mances of the AM-OLED Display (such as voltage-current
brightness
chromaticity coordinates
etc) could be measured in the same software. First
we built the hardware circuit: the driving circuit based on FPGA for AM-OLED Display. Then
a software system of
V-I-L
testing system based on virtual instrument technology was designed on this basis. Finally
we tested the 12.2 cm AM-OLED Display based on MOTFT technology which is developed independently
and verified the reliability of the system. Through the analysis of the test results
the data voltage of each pixel was about 9.2 V when the brightness of AM-OLED Display reached to the value of calculation.In brief
this system can achieve the automatic test of the Displays' performance parameters and make an assessment on screenperformance. What's more
it can not only provide reference data for the white balance adjustment and the design of AM-OLED driver IC
but also show the direction for the optimization design on the screen.
