Abstract
Dual display control device and method using an RGB interface are provided. A dual display control device controlling a first display device and a second display device using an RGB interface includes: a synchronization signal output unit that outputs vertical and horizontal synchronization signals to the first display device and the second display device; and a data output unit that outputs first data to the first display device in a first section of a first pixel clock and outputs second data to the second display device in a second section of a second pixel clock, in accordance with the vertical and horizontal synchronization signal via a data line shared by and connected to the first display device and the second display device. Accordingly, it is possible to reduce the number of signal lines, thereby embodying an efficient hardware configuration.
