Mixed monochrome and colour display driving technique
First Claim
1. A method for practicing multiple scanning modes on a display screen in a handheld wireless communications device, comprising:
- scanning a first region of contiguous lines of pixels at a first number of times in a frame period; and
scanning a second region of contiguous lines of pixels at a second number of times in the frame period, wherein the first number of times is not equal to the second number of times.

Abstract
A display screen is capable of having regions having different switching speeds as well as regions that are not switched. One region having a first switching speed may be for colour mode display and the other region having a second switching speed different from the first may be for monochrome mode display. Other regions may be off and not switched. In alternative versions, three or more switched regions may be established on a display screen. For example, a monochrome region may be nested inside a colour region, in which the colour region may be nested between off regions.
