Abstract

Disclosed is a method for estimate the power consumption for display pattern. Power consumption of display changes by display pattern. And power consumption is different by display driving method (normally white or black etc), data transfer method (TTL or differential etc). By preparing the typical pattern parameter for each display, users can estimate the power consumption for every display pattern.

Power consumption estimation method for display pattern

Power consumption for display pattern can be estimate by counting display pattern how many bright pixels and data switching there are. By making parameters for each display to typical display pattern, users can estimate every display pattern. Estimation flow is shown in Fig.1, for example.

Start

Read panel ID

Read parameters for panel ID

Open the display pattern file (wallpaper)

   Read the RGB information from the file

Calculate the score using parameters

Display the score

End
