Abstract: A source driver and a method for color swapping are provided. The source driver includes: a processor configured to: obtain, from an application processor, a plurality of sub-pixel data, add a tag to each of the plurality of sub-pixel data to generate a plurality of new sub-pixel data, the tag indicating color information of the sub-pixel data, and perform color swapping on the plurality of new sub-pixel data; a multiplexer circuit communicatively coupled to the processor and configured to: obtain each of the plurality of color swapped new sub-pixel data in sequence, and select a corresponding gamma voltage according to the tag of the color swapped new sub-pixel data; and an analog amplifier circuit communicatively coupled to the multiplexer circuit and configured to provide a source driving signal to a corresponding sub-pixel in a pixel array according to the color swapped new sub-pixel data and the corresponding gamma voltage.

Abstract: A method for automatically notifying an intended person of a service interval of a test and measurement device by using the test and measurement device is described, wherein service data is received by the test and measurement device. The service data is processed internally. A time for maintenance is calculated automatically based on the service data retrieved. Further, a test and measurement device is described.
