| | 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. |
