HiL testing of TFT clusters using Vector VT system

In an automobile, infotainment plays a vital role in attracting customers and satisfying their needs. Many technologies such as navigation and telematics are being developed to fulfill the untold needs of individuals. TFT (Thin Film Technology) display is one of such technologies used in digital Cluster for better high-definition display & best experience for users. Validation of TFT Clusters by changing all its features and images incorporated in the screen is important for the product. Vector VT (Virtualization Technology) system is a high-performance modular system for ECU testing which is used to test all the features of the TFT Cluster. Vector CAPL programming is used to program the test conditions for the features of the Cluster. A switch test rig is integrated along with the system to test the available mechanical switch features in Cluster. During the test, glitches in TFT d isplay screen are observed and the analysis for the cause and actions are taken which is discussed in this paper.
