Shared buffer display panel drive methods and systems

摘要

Methods of driving source lines and/or circuits/systems for driving source lines are provided. Source lines of a display device are driven by comparing first data for driving a first buffer associated with a first source line of the display device and second data for driving a second buffer associated with a second source line of the display device and selectively disabling the second buffer and driving the second source line of the display device with the first buffer based on the comparison of the first and second data.

主权项

1. A method of driving source lines for a display device comprising:
determining whether a plurality of digital data, including first digital data for a first pixel and second digital data for a second pixel, have a same value; disabling a first group of buffer amplifiers that are coupled to a first source line, if the first digital data and the second digital data have the same value; electrically coupling each output of the first group of buffer amplifiers with respective output of a second group of buffer amplifiers that are coupled to a second source line, if the first digital data and the second digital data have the same value; and outputting amplified signals from the second group of buffer amplifiers both for first pixel data associated with the first pixel and for second pixel data associated with the second pixel in a display panel, if the first digital data and the second digital data have the same value.
