Abstract:
1. A mobile telecommunication terminal having a main body, the mobile telecommunication terminal comprising: a processor disposed in the main body configured to perform operations of the mobile telecommunication terminal; a digital display coupled to the main body configured to display information; and an interface device configured to transmit signals to the digital display, wherein the interface device comprises: a data bus coupled to the processor, the data bus comprising graphic signal lines, a data enable line, and a clock line, a digital-to-analog converter for converting digital pixel information to an analog color signal, wherein the digital-to-analog converter is operatively connected to the data bus, and an analog-to-digital converter for converting the analog color signal to digital pixel information, wherein the analog-to-digital converter is operatively connected to the data bus, wherein the digital-to-analog converter is located in the main body and the analog-to-digital converter is located in the display, and wherein the graphical signal lines transmit a command signal from the processor or the analog color signal from the digital-to-analog converter according to a state of the data enable line, such that the command signal is transmitted to the analog-to-digital converter when the data enable line is maintained at a first state and the analog color signal is transmitted to the digital display when the data enable line is at a second state.
