A lamp connector allows for checking of a connection between an external electrode of an external electrode tubular lamp and a terminal fitting into which the external electrode is fitted. Because the lamp connector into which an external electrode provided on the outer surface of an end portion of a tubular lamp is fitted includes a terminal fitting which includes a terminal piece and a terminal piece insulated from each other which are to be individually brought into contact with the external electrode, it is possible to easily check conduction between the external electrode and the terminal fitting using a tester. Accordingly, any poor fitting of the lamp into the connector can be readily found and corrected.

An objective of one embodiment of the present invention is to reduce abrupt noise derived from infrared light emitted by a light source from a data signal of infrared light received by an infrared communications receiver for use with a display device including a light source without reducing the strength of the data signal. A multiplication factor for the amplitude of abrupt noise outputted by a lamp light-receiving element disposed in the vicinity of lamps of a liquid crystal television is adjusted in order for the amplitude of abrupt noise derived from the lamps and outputted by the lamp light-receiving element to be equalized with the amplitude of abrupt noise derived from the lamps and included in a data signal outputted by a data light-receiving element. Then, the abrupt noise subjected to multiplication factor adjustment is subtracted from the data signal including the abrupt noise, so that only the data signal remains and is transmitted to the liquid crystal television.

Infrared communications receiver

An objective of one embodiment of the present invention is to perform infrared communications without error by reducing abrupt noise included in a data signal when a light source of a display device is driven by PWM drive. When a control portion is provided with a drive setting signal for determining whether to drive lamps of a liquid crystal television by pulse width modulation drive or by continuous drive, the control portion sets a threshold in a register for a frequency filter portion based on the provided drive setting signal. Furthermore, upon reception of infrared light from the lamps, the threshold being set is reviewed based on an occurrence frequency for abrupt noise provided by a waveform analysis portion. Thereafter, abrupt noise included in a data signal transmitted from a cell phone is reduced by the frequency filter portion, and then the data signal is transmitted to the liquid crystal television.
