    Abstract: A display unit of which inspection process to inspect a connector for faulty connection can be automated. The display unit comprises a liquid crystal display section, a display driver IC driving the liquid crystal display section, a first board on which the display driver IC is mounted, an MPU sending a command and other information to the display driver IC, a second board on which the MPU is mounted, and a connector electrically connecting the first and second boards to each other. The MPU has a means for sending a test command in the test modes and reading the inspection result signal output from the display driver IC thereafter. The display driver IC comprises an interface circuit outputting and inputting a signal to and from the MPU, a command decoder decoding the test command input from the MPU via the interface circuit, and an inspection circuit outputting the inspection result signal in accordance with the signal from the command decoder. The MPU reads the inspection result signal that is input via the interface circuit and connector, whereby it is possible to judge when the connection of the connector is faulty.

    Abstract: An oscillation device includes a buffer device, a feedback device for feeding back an output of the buffer device to an input thereof and a charging device and a discharging device connected to the input of the buffer device. The charging device includes a first switching device that is turned on and off based on the output of the buffer device and a first current control device that controls the current flowing into the input of the buffer device through the first switching device. The discharging device includes a second switching device that is turned on or off based on the output of the buffer device and a second current control device that controls the current flowing out of the input of the buffer device through the second switching device. The first and second switching devices include first and second transistors and the first and second current sources that include third and fourth transistors. The oscillation device includes a bias circuit that controls at least the current ratio of the first and second current of the first and second current sources by controlling bias voltages applied to first and second bias terminals of the oscillation device.
