Abstract: A control circuit of a power converter and a control method thereof are provided. The control circuit includes an error amplifier, a controller, a digital filter, and a digital pulse width signal modulator. The error amplifying circuit is coupled to an output terminal of the power converter and provides a digital error signal. The controller provides a first working parameter corresponding to the first external control command when receiving a first external control command. The digital filter generates a current digital compensation value. The digital pulse width signal modulator generates a pulse width modulation signal. The controller provides a second working parameter corresponding to the second external control command when receiving a second external control command. The controller calculates a transition value according to the second working parameter and the current digital compensation value. The controller provides the second working parameter and the transition value to the digital filter.

Abstract: The disclosure relates to a display method and a display system. The display method includes: connecting a plurality of display devices in series with each other, the plurality of display devices including a main display device and at least one slave display device, the main display device having EDID; setting the connection order of the display device; correspondingly changing the EDID of the main display device according to the connection order of the display device; configuring the main display device to receive the display image according to the changed EDID; and configuring the display device to perform an image segmentation operation on the display image according to the connection order to respectively display multiple segmented regions of the display image.

Abstract: A color adjusting method is applied to a projector. The projector has a light emitting element and a color wheel. The light emitting element supplies light, and makes the light pass through the color wheel so as to generate a plurality of different color lights. These different color lights are used to form a color image. The color adjusting method includes the steps of providing a plurality of driving waveforms which is dynamically switched for driving the light emitting element; defining a major color light of the color image, which is selected from the different color lights; and switching to one of these driving waveforms when the major color light is generated by the light passing through the color wheel. Thus, the light energy of the major color light is enhanced by means of driving the light emitting element through the switched driving waveform.
