摘要： The disclosure discloses a driver chip, a driver board and a test method thereof, and a display device. The driver chip comprises: a first internal interface; a second internal interface; and a test circuit for performing a short-circuit detection on the internal interfaces, which comprises an input unit and a test unit. The input unit is connected with a test signal input terminal, the test unit and the first internal interface, respectively, and used for transmitting a test signal inputted via the test signal input terminal to the test unit and the first internal interface when in an ON state. The test unit is connected with the second internal interface and a test signal output terminal, respectively, and used for preventing a signal outputted by the input unit from being outputted from the test unit to the test signal output terminal and the second internal interface when in an OFF state. According to embodiments of the disclosure, it can be detected whether short-circuit has occurred to interfaces on the driver chip before the driver chip begins to work.
摘要翻译：本发明公开了一种驱动芯片，驱动板及其测试方法，显示装置。该驱动芯片包括：第一内部接口; 第二内部接口; 以及用于对内部接口执行短路检测的测试电路，其包括输入单元和测试单元。输入单元分别与测试信号输入端，测试单元和第一内部接口连接，用于在测试单元和第一内部接口处于开启状态时，将经由测试信号输入端输入的测试信号发送至测试单元和第一内部接口州。测试单元分别与第二内部接口以及测试信号输出端连接，用于防止输入单元输出的信号在测试时从测试单元输出至测试信号输出端和第二内部接口 OFF状态。根据本公开的实施例，可以在驱动芯片开始工作之前检测驱动芯片上的接口是否已经发生短路。

摘要： A shift register unit, a shift register and a display apparatus are provided. The shift register unit comprises a voltage-boosting module configured to output a first level signal when receiving a gate driving signal sent from the previous stage of shift register unit; a signal output module configured to output a gate driving signal under the control of a first clock signal based on the first level signal output by the voltage-boosting module; a reset module configured to control the signal output module to reset under the control of a reset signal; and a pull-down module configured to pull down the output level of the signal output module under the control of a second clock signal. It is possible to reduce the power consumption of the integrated circuit and avoid the abnormal waveform issue due to the decay of the reset signal by employing the technical solutions of embodiments of the present disclosure.
