Display device capable of in-display sensing
摘要:
The present invention is related to a display device, including: a plurality of sub-pixel areas, each including a pixel circuit, each pixel circuit including: a diode, configured to be in a forward-biasing state during a displaying phase of the pixel circuit for emitting light and configured to be in a reverse-biasing state in a sensing phase of the pixel circuit so as to generate a sensing voltage; a first circuit by applying gate control signals to each pixel circuit, so that each pixel circuit switches between the display phase and the sensing phase, respectively; and a second circuit including a plurality of readout circuits, each readout circuit includes an operational amplifier for reading out the sensing voltage in the sensing phase.
