Display screen information providing method for passive matrix LCD in mobile data processing system for motor vehicle, involves determining characteristic value based on screen information, and providing value for application of LCD device

摘要

The method involves determining a characteristic value (K) based on display screen information, where the characteristic value is representation for the number of pixels activated in a LCD device (2). The characteristic value is provided for application of the LCD device. The characteristic value is determined for changing an operating voltage of a display driver (20) of the LCD device. Surrounding temperature of the LCD display is considered during changing the operating voltage of the driver. Independent claims are also included for the following: (1) a method for displaying display screen information in a LCD device (2) a graphic controller of a mobile data processing system for executing a method for providing display screen information for a LCD device (3) a program code for executing a method for providing display screen information for a LCD device.
