with an external clock thus the rgb interface is suitable to display high resolution images compared with the cpu interface with the continuing development of multimedia however a method for displaying high resolution images should be provided in mobile terminals to support the multimedia if a modem chip or ap chip supporting the actual resolution of qvga 240 u00d7 320 or wqvga 240 u00d7 400 is provided in a mobile terminal the cpu interface is also available however if the cpu interface is used when the performance has been improved to the resolution of wvga 800 u00d7 480 or 854 u00d7 480 class there is needed a modem chip and an ap chip which have a high performance cpu and the existing display panels cannot be used considering this the present invention uses the rgb interface that can easily display high resolution images compared with the cpu interface a description will now be made of a structure of a control apparatus for displaying high resolution images through an lcd panel and a projector driver in a mobile terminal that supports a projector function using an rgb interface a first embodiment of the present invention controls images being transmitted to an lcd panel and a projector driver through their associated paths using cs signals a second embodiment of the present invention controls data being transmitted to an lcd panel only when the lcd panel needs an image update while the projector function is in operation fig2 illustrates an internal structure of a mobile terminal with a projector function according to the first embodiment of the present invention a dual display control apparatus according.
