Low complexity gate line driver circuitry

An electronic device comprising:

• a plurality of gate lines, with a respective near hold circuit and a respective far hold circuit coupled to each of the gate lines;
• a first plurality of gate drivers each of the first plurality of gate drivers being coupled to drive an associated odd numbered one of the gate lines, when the gate lines are numbered sequentially;
• and
• a second plurality of gate drivers each of the second plurality of gate drivers being coupled to drive an associated even numbered one of the gate lines,
• wherein for each gate line, the respective near hold circuit is located closer to an associated gate driver, that is coupled to drive the gate line, than the respective far hold circuit,
• and wherein each of the gate drivers is further coupled to control a) the respective near hold circuit of an associated gate line and b) the respective far hold circuit of a neighbor gate line, and wherein each of the second plurality of gate drivers has two output stages that are controlled by the same latch stage and that are coupled to drive a respective pair of the associated even numbered gate lines.

An electronic device comprising:

• a touchscreen system having
• a plurality of display elements,
• a touch transducer,
• a plurality of gate lines coupled to the display elements,
• a plurality of gate drivers each having a latch stage driving an output stage, the output stage being coupled to drive a current gate line, wherein each gate driver further comprises another output stage that is controlled by the latch stage and is coupled to drive another gate line, and the latch stage being coupled to drive a) a first hold circuit that holds the current gate line at a predetermined voltage, and b) a second hold circuit that holds a previous gate line at a predetermined voltage, and
• controller circuitry that is coupled to the touch transducer and the gate drivers, the controller circuitry to generate a) a start pulse that is fed to one of the gate drivers and b) a plurality of clock signals that are fed to each of the gate drivers, when updating the display elements during a frame interval, the controller circuitry to read the touch transducer during a blanking interval in which the latch stage directly maintains gate electrodes of the first and second hold circuits at a fixed voltage without using a separate blanking control signal to directly control the gate electrodes, so as to hold the gate lines at the predetermined voltage.
