Abstract: A display system includes: a display device including a plurality of self-luminous elements; and a control device configured to control an operation of the display device. The control device is configured to cause the display device to: display a normal video through use of gradations of up to luminance equal to or lower than normal maximum luminance; and display a part of a video, as required, through use of a boost light emission in which some of the self-luminous elements are caused to emit light at luminance exceeding the normal maximum luminance.

Abstract: An LED panel includes a plurality of LED pixel units being arranged. Each of the plurality of LED pixel units includes: a normal element including a red LED element, a green LED element, and a blue LED element; and a low-luminance element configured to provide an output having luminance lower than the lowest luminance of the normal element.

Abstract: An LED driver circuit capable of overcoming the issues in that a brightness change is perceived as a stepped change in a very low light amount region or light abruptly goes out by using PWM control and of realizing smooth dimming even at a very low amount of light is provided. In the LED driver circuit, a first circuit including a first resistor and a first power transistor connected in series and a second circuit including a second resistor and a second power transistor connected in series are connected in parallel with each other and are connected to an LED. First and second PWM signal generator circuits drive the first and second power transistors, respectively. When the first and second power transistors are in an on-state, currents flow through the LED via the first and second resistors, respectively, which enable a smooth brightness change even in a low illuminance region.
