Dimming is achieved by turning the lamp on and off at a frequency of approx. PWM Control (Burst Dimming) The Piccolo model uses PWM fully from OSD 0 to 100. 2:1) -Because the inverter is optimized to the maximum brightness, the efficiency is degraded in the dimming state.2. A minimum current is required with which no partial lightning occurs in the lamp at the minimum brightness. Current Control (Analog Dimming) - Dimming is possible with comparatively no effect on the panel. The Complex method mixes those two methods.ġ. The PWM method turns the lamp on and off according to a specific frequency. The Current Control method adjusts the size of the current entering the lamp. It is used in circuits that stabilize the DC voltage. The memory to which analog DDC data is input An IC that receives DC voltage inputs.
