摘要： A source driver of a display panel includes a channel state signal generator, first switches, and second switches. The channel state signal generator generates first and second channel state signals that are each activated for a respective time period depending on adjustable state length data. The first switches are opened for uncoupling channel output signals from source lines of the display panel when the first channel state signal is activated. The second switches are closed for coupling together the source lines of the display panel for charge sharing when the second channel state signal is activated.

摘要： A display device includes a first set of data buses coupled between a timing controller and a first line driver. In addition, the display device also includes a second set of at least one data bus coupled between the first line driver and a second line driver. The second set has a less number of at least one data bus than the first set. Thus, data signals are transmitted to the line drivers of the display panel from the timing controller with minimized wiring for reduced power consumption and electromagnetic interference.

摘要： For generating source line voltages in a display device, gray scale data is received at a source driver for a first sub-pixel of a pixel. The source driver generates a first source line voltage for the first sub-pixel and a second source line voltage for a second sub-pixel from the gray scale data of the first sub-pixel. Thus, data transfer rate and/or data buses are minimized for in turn minimizing power consumption and EMI (electromagnetic interference).
