Abstract: A scan-type display apparatus includes an LED array and a data driver. The LED array has a common anode configuration, and includes multiple scan lines, multiple data lines and multiple LEDs. The data driver includes multiple data driving circuits, each of which includes a current driver and a detector. The current driver has an output terminal connected to the data line corresponding to the data driving circuit, and outputs one of a drive current and a clamp voltage at the output terminal of the current driver based on a pulse width control signal. The detector is connected to the current driver, and generates a detection signal that indicates whether any one of the LEDs connected to the data line corresponding to the data driving circuit is short circuited based on a detection timing signal and a feed-in voltage related to a voltage at the output terminal of the current driver.

Abstract: A scan-type display apparatus includes an LED array and a scan driver. The LED array has a common anode configuration, and includes multiple scan lines, multiple data lines and multiple LEDs. The scan driver includes multiple scan driving circuits. Each scan driving circuit includes a voltage generator and a detector. The voltage generator has an output terminal that is connected to the scan line corresponding to the scan driving circuit, and is configured to output one of an input voltage and a clamp voltage at the output terminal of the voltage generator. The detector is connected to the output terminal of the voltage generator, and generates a detection signal that indicates whether any one of the LEDs connected to the scan line corresponding to the scan driving circuit is short circuited based on a voltage at the output terminal of the voltage generator and a detection timing signal.

Abstract: A fluorine-containing elastomer composition includes a curable fluorine-containing polymer comprising at least one fluorinated cure site monomer having a cure site; an group IIIB element-containing reinforcing additive in an amount of 8 to 15 weight parts with respect to 100 weight parts of the curable fluorine-containing polymer; and a curative configured for curing the at least one fluorinated cure site monomer.

Abstract: An improved structure of an ignition sparking plug having a grounding electrode and a central electrode is disclosed. The grounding electrode has a tip end with respect to the central electrode so that the only a small part of the central electrode is shielded by the grounding electrode. Thereby, mixed gas enters into the space between the grounding electrode and the central electrode rapidly so as to be ignited and then explode quickly to push the piston. Therefore, the piston can move reciprocally. Since the grounding electrode has a smaller volume, the generated spark has a large volume and absorbs a little thermal energy. Since electric discharging occurs in a tip point, the efficiency of ignition is high so as to improve the air to oil ratio in the cylinder and thus oil is saved and exhausted waste is reduced.
