摘要： A display device includes a lamp unit, a dimming signal controller, and an inverter device. The dimming signal controller receives a lamp brightness signal and an external environment illumination signal, selects the lamp brightness signal or a signal based on the received external environment illumination signal, and outputs the selected signal as a dimming signal. The inverter device may operate to control brightness of the lamp unit based on the dimming signal.

摘要： A full bridge switching circuit includes a converter circuit including first and second converters. The first converter includes a first transformer and a first switching element part to control the first transformer in response to a first switching signal. The second converter includes a second transformer and a second switching element part to control the second transformer in response to a second switching signal. The first and second transformers are controlled by the first and second switching element parts to output first and second feedback signals, respectively. The full bridge switching circuit further includes a third switching element part having a third switching input connected to the first and second transformers, and an IC circuit to generate an OR signal by an OR operation of a first control signal generated from the first feedback signal and a second control signal generated from the second feedback signal.

摘要： A display device including two or more lamp groups, each having one or more lamps, includes a driving control signal generating unit and an inverter unit. The driving control signal generating unit generates driving control signals to control the driving of at least one of the two or more lamp groups. The inverter apparatus includes two or more inverter circuits configured to receive the driving control signals. In the display device, each of the two or more inverter circuits sets the operation frequency of a corresponding lamp group based on the driving control signals, and generates an operation voltage for the corresponding lamp group according to the set operation frequency.
摘要翻译：包括两个或更多个灯组的显示装置，每个具有一个或多个灯，包括驱动控制信号产生单元和逆变器单元。驱动控制信号生成单元生成驱动控制信号，以控制两个以上的灯组中的至少一个的驱动。逆变器装置包括被配置为接收驱动控制信号的两个或多个反相器电路。在显示装置中，两个以上的逆变器电路中的每一个基于驱动控制信号设定对应的灯组的工作频率，并根据设定的工作频率生成对应的灯组的动作电压。
