Abstract
A time division driven display and a method for driving the same. The display includes a panel having data lines, a source driver having output pins, a precharge controller and a demultiplexer. The precharge controller electrically connected to these data lines selects one from these data lines to precharge. The demultiplexer coupled to the output pins and these data lines couples the corresponding output pin to the selected data line for the source driver to drive the selected data line after the selected data line is precharged.
Claims16
A time division driving method for driving n data lines, comprising a data line (1) to a data line (n), of a display within a charging period, wherein n is a positive integer, the charging period is divided into a plurality of sub-charging periods, comprising a sub-charging period (0) to a sub-charging period (n), the method comprising the steps of:
- selecting the data line (i) from the data lines, wherein i is a positive integer smaller than or equal to n;
- selecting at least one sub-charging period from the sub-charging periods (0) to (i−1);
- precharging the data line (i) within the at least one selected sub-charging period;
- driving the data line (i) within the sub-charging period (i);
- and
- repeating the above-mentioned steps until the data lines have been driven.
A time division driven display, comprising:
- a panel, which includes a plurality of data lines;
- a source driver, which includes at least one output pin;
- a precharge controller, which is electrically connected to the data lines, for selecting one of the data lines to precharge;
- and
- a demultiplexer, which is coupled to the at least one output pin and the data lines, and connects the selected data line to the at least one output pin to enable the source driver to drive the selected data line after the selected data line is precharged.
