Demand for display resolution in Android-based tablets is rapidly increasing from WXGA (800 x 1280) to WQXGA (1600 x 2560). As the market requires a display of 300 PPI (Pixel Per Inch) or more, display is one of the most critical power source with high performance Application Processor (AP). This paper introduces a 2-chip display driver architecture for A-Si LCD WQXGA resolution display to reduce power consumption in tablet display system. The paper also shows the cost benefits of 2-chip display driver architecture when compared to conventional Timing Controller (T-CON) and multi column drivers solution in a tablet display system.
