摘要: This disclosure provides systems, methods and apparatus for a display apparatus including dummy display elements that can be switched between being coupled to a test bus and a drive bus. When connected to the drive bus, the circuit components, including thin-film transistors, of the dummy display element experience exposure to typical operating loads. When connected to the test bus, the display apparatus can test the operating parameters of the dummy display element circuit components.

摘要: This disclosure provides systems, methods, and apparatus for providing a cascode driver circuit for providing positive and negative polarities of two or more voltages at an output node. The voltages provided by the cascode driver circuit can be used to provide voltages to various interconnects and terminals of the display apparatus. The cascode driver circuit includes a first circuit for providing a positive polarity of two or more voltages to an output node via a first set of cascode transistors and a second circuit for providing negative polarities of the two or more voltages via a second set of cascode transistors. The driver circuit includes body-effect mitigation circuitry for reducing the impact of body-effect on the performance of the driver circuit. The driver circuit also includes circuitry for reducing substrate leakage current.
