摘要： In a plasma display panel, an analogue brightness value given by a variable resistor is periodically converted into a digital brightness value and stored in a memory. A digital brightness value of a current period is compared with the digital brightness value of the next preceding period stored in the memory, to produce a difference brightness value which is compared with a predetermined brightness value and, if larger than the predetermined value, the brightness value stored in the memory is updated. Alternatively, power consumption of a display device is detected and, when the power consumption is larger than a set point, a brightness value is gradually decreased and, when the power consumption is smaller than the set point, the brightness value is gradually adjusted to a brightness set value.

摘要： A display for performing gray-scale display according to a subfield method, in which the frame memory area is minimized, has been disclosed. The display comprises: a main unit including a video signal source and a display interface having a frame memory; a display panel unit including a matrix panel for performing gray-scale display according to the subfield method, a driver for driving the matrix panel, and a display control unit for receiving display signals from the display interface in the main unit and controlling the driver according to the display signals; and a cable for linking the main unit and display panel unit. The display interface transmits display signals covering one frame in units of a subfield. This obviates the necessity of a frame memory that is employed in a known display adopting a CRT interface as an interface between the main unit and display panel unit and that is used to convert display signals adapted to the CRT interface into those adapted to the subfield method.

摘要： When a MOS transformer switch 14 shifts from an ON state to an OFF state, a fly-back spike voltage is induced from a secondary winding 122 to a primary winding 121. As a result electric charge accumulates in a capacitor 281, via a diode 283 and a voltage, i.e. is the voltage of a battery 10 on to which the voltage between terminals of the capacitor 281 is stacked, is supplied to the DC power-supply voltage input terminal Vcc of a control circuit 16 via a LC low pass filter 34A. Energy stored in the capacitor 281 may be effectively utilized, while the fly-back spike voltage to the control circuit 16 side is cut by a LC low pass filter 34A.
