Abstract Effect of Predominant Pixel Color Variation on Computer Monitor Power

Consumption



With numerous uses of energy in today’s society, over usage of energy is

highly abundant. Because the excessive usage of energy may result in

environmental and sociopolitical impacts, methods of reducing Power

consumption are always desirable. Through experimentation, this work

may offer a promising new method to reduce the amount of Power

consumption of a computer monitor through use of different screen pixel

color predominance.



Data required for this experiment includes Voltage levels of the computer

monitor during the display of each individual color template on the computer

monitor. Additionally, current flow of the computer will be measured for

Power consumption calculation.



Different computer templates of visible spectrum colors will be prepared, in

addition to the standard black and white color. A standard computer

monitor is prepared, with exposed sensing circuitry so as to readily

measure power consumption through the Central Processing unit.



Voltage levels will be measured through use of a voltmeter. Probes of the

voltmeter will be attached to different areas of sensing circuitry on the

computer monitor to measure the current voltage of the monitor when

different color templates are displayed. An ammeter is used to measure

electrical current flow for the computer monitor.



Each color template is displayed on the screen, and Voltage levels are

measured for three trials for each separate color template. Collaterally, this

results in a total of 36 trials, with three trials for nine color templates.



Once Voltage levels are recorded, they are multiplied by the Current Flow

of the Computer monitor to yield levels of Power Consumption for each

individual color. All results are compared.
