- Questions about Light-Emitting Display Apparatus:**
1. How does the power supply adjust the stage driving voltage in response to the dummy stage sensing signal?
- The power supply adjusts the stage driving voltage based on the feedback received from the gate driver's dummy stage sensing signal to optimize performance.
2. What role does the control driver play in the overall operation of the display apparatus?
- The control driver receives determination signals related to abnormalities from the data driver and adjusts the power supply to maintain the proper level of the stage driving voltage based on a lookup table.
Original Abstract Submitted
a light emitting display apparatus can include a panel including a gate driver configured to output gate pulses and pixels configured to display an image; a power supply configured to supply a stage driving voltage to the gate driver and adjust a level of the stage driving voltage based on a dummy stage sensing signal received from the gate driver; and a data driver configured to supply data voltages to the pixels and generate a determination signal related to an occurrence of an abnormality in the gate driver based on a monitoring signal received from the power supply. also, the light emitting display apparatus can further include a control driver configured to receive the determination signal from the data driver and control the power supply to adjust the level of the stage driving voltage based on a lookup table.
