LCD灰阶响应时间自动测量系统开发

的：灰阶响应时间需要测试不同灰阶之间切换需要的时间，这样测试的数据量是非常大的。如：9级灰阶，需要的的测试数据量就是9*（9-1）=72个。仅仅靠手动测试已经很难完成该测试。需要自动化的测量方法才能完成。方法：对LCD的灰阶响应时间自动测量进行了研究，用综合测试仪（DMS）与FPGA系统结合的方案完成灰阶响应时间的自动测量，可以快速准确的测试灰阶响应时间。结果：采用这个方案可以在无需额外购买测试设备的情况下几分钟内测试一组灰阶响应时间，测试基准采用DMS设备，所以测试的准确率高。结论：该自动测试方案对于LCD灰阶响应时间的测量和研究具有很强的实用价值。

Automatic Test Method of LCD Grey-to-Grey Response Time

LCD grey-to-grey response time must test the switch time between different Grey.Grey-to-grey test have large amount of data.For example test 9levels grey-to-grey response time the result have 9*(9-1)=72 data.So it is very difficult to test manually.Automatic test method of LCD grey-to-grey response time are studied .Combined with DMS-501 and FPGA test system can get the grey-to-grey data rapidly.Normally grey-to-grey switch time can be tested in few minutes.And DMS can assure the test quality.The test method can be used to test and analysis the LCD grey-to-grey switch time.
