Abstract
The present disclosure is directed to a gate driver circuit configured to prevent a light-emitting element of a display device from emitting light in a sensing mode. The gate driver circuit allows a plurality of scan lines of the display device being concurrently sensed by pre-charging a node of the gate driver circuit prior starting a sensing mode. The present disclosure provides the benefit of sensing a greater number of pixels of a display in a shorter time while also ensuring that a sufficient charge is provided by the pre-charged node for a plurality of pixels of the plurality of scan lines to be sensed concurrently.
