摘要: 本论文系就薄膜电晶体液晶显示器工业检测技术所需,设计出结合液晶盒电压保持率、残余直流电压特性与自动化温度控制电路的多功能量测设备。为提高此装置的应用性及量测范围,本团队利用简单的温度控制系统之电子电路搭配加热晶片与散热系统,整合现有系统电路及整体装置架构,透过资料撷取装置与虚拟仪控介面达到量测与数值分析高度自动化的结果,提出具可携式、易操作、高准确性及广泛应用之温度可调式液晶盒量测装置,并且用来探讨扭转与水平排列之向列液晶的电压保持率与残余直流电压特性。
According to the requirement on the detection of display performance in thin film transistor liquid crystal display (TFTLCD), a multi-functional instrument for the measurement of voltage holding ratio (VHR), residual direct current (RDC), and electro-optical characteristics of liquid crystal cells have been developed by our research group. In order to expand the application field and measurement range for abovementioned parameters, in this study, a simple temperature-control system consisting of heating chips and cooling systems is designed and combined into our proposed instrument. We also integrate various types of circuits and whole framework for the instrument to obtain highly automatic measurement and numerical analysis through the data acquisition and interface of virtual instrument control. Furthermore, electrical properties such as the VHR and RDC, of twisted nematic and planar-aligned liquid crystal cells under specific measuring conditions are presented.
