DISPLAY PANEL HAVING AN INPUT SENSING FUNCTION AND A DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18218220 titled 'DISPLAY PANEL HAVING AN INPUT SENSING FUNCTION AND A DISPLAY DEVICE
Simplified Explanation
The patent application describes a display panel that includes both light emitting pixels and light sensing pixels.
- The light emitting pixels emit light in response to specific scan signals and a light emission control signal.
- The light sensing pixels output a sensing signal that corresponds to external light in response to the same scan signals.
- Each light emitting pixel contains an organic light emitting diode (OLED) with an anode and a cathode.
- The cathode of the OLED receives a first driving voltage.
- Each light sensing pixel contains an organic photodiode with a first electrode and a second electrode.
- The second electrode of the organic photodiode is electrically connected to the cathode of the OLED to receive the first driving voltage.
Original Abstract Submitted
A display panel including: a plurality of light emitting pixels which emit light in response to a first scan signal, a second scan signal, and a light emission control signal; and a plurality of light sensing pixels which output a sensing signal corresponding to external light in response to the first scan signal and the second scan signal, wherein each of the plurality of light emitting pixels includes an organic light emitting diode including an anode and a cathode, the cathode receiving a first driving voltage, and each of the plurality of light sensing pixels includes an organic photodiode including a first electrode and a second electrode, wherein the second electrode of the organic photodiode is electrically connected to the cathode of the organic light emitting diode to receive the first driving voltage.
