Abstract
The invention relates to a multi-layer overlapping display method and device for a mobile terminal. For some frequently-used interfaces on a cell phone terminal, a part where an unclear display effect may appear in a multi-layer overlapped area can be automatically adjusted through the method and device. Compared with an existing layer overlapping technology, the technology has the advantages that readjustment and superposition operation do not need to be conducted on a whole layer in the multi-layer overlapped area, but firstly, detection is conducted to select areas which need to be adjusted in the layer, then, the specific areas which need to be adjusted are adjusted, and therefore the influence on the cell phone calculating speed is greatly reduced. According to a cell phone utilizing the method and device, the best frequently-used interface displaying effect can be obtained under the condition that the influence on the performance of the cell phone is reduced to the maximum extent.
