Palm Receives Display Technology Patent
In a rather unexpected nod to the retro screen technology of yore, Palm has recently received patent #7002569 from the USPTO. The new software patent covers the ability to make the screen to go into monochrome mode in order to extend battery life on mobile devices.
In theory, this could reduce a mobile device's power consumption to as little as 25% of what is normally required to power a fully backlit color transreflective LCD. Color would then be restored upon sufficient battery recharging.
Assuming mono mode can be toggled for fulltime operation, some long-time Palm users may even choose to always run in mono mode in order to have battery life measured in days instead of hours.
Some excepts from the patent filing:
"The monochrome display mode can be selected by the user when the battery level is detected below a predefined threshold."
"When the battery level is detected as below a preselected level, a message is generated on the computer display screen. The message informs the user that the display mode of the screen can be changed to enhance the battery life. If selected, the display mode can change from color to monochrome thereby saving power because the monochrome display does not utilize a back-lighting element. "
