DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18125622 titled 'DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME
Simplified Explanation
The patent application describes a display apparatus that includes a display panel, gate driver, data driver, sensing circuit, power voltage generator, and driving controller. The driving controller is responsible for stopping the display panel and related components if any defects are detected.
- The display apparatus includes a display panel with pixels, a gate driver, a data driver, a sensing circuit, a power voltage generator, and a driving controller.
- The gate driver outputs gate signals to the pixels, while the data driver outputs data voltages to the pixels.
- The sensing circuit receives sensed signals from the pixels, allowing for the detection of any defects.
- The power voltage generator applies a power voltage to the display panel.
- The driving controller is responsible for stopping the display panel, gate driver, data driver, and power voltage generator if any defects are determined.
- The driving controller selects a first-mode threshold set or a second-mode threshold set based on an initial value set related to the sensed signals to determine if the display panel is defective.
- The first-mode threshold set and the second-mode threshold set have different thresholds that correspond to different defect detection criteria.
Potential applications of this technology:
- Display panels in electronic devices such as smartphones, tablets, and televisions.
- Industrial displays used in control rooms, manufacturing facilities, and transportation systems.
- Advertising displays in public spaces, shopping malls, and stadiums.
Problems solved by this technology:
- Efficient detection of defects in display panels.
- Preventing the use of defective display panels, which can lead to poor image quality and reduced lifespan.
- Minimizing the risk of damage to other components by stopping the operation of the display panel and related drivers.
Benefits of this technology:
- Improved display panel quality by detecting and stopping the use of defective panels.
- Enhanced user experience with better image quality and reliability.
- Cost savings by preventing the use of defective panels and reducing the risk of damage to other components.
Original Abstract Submitted
A display apparatus includes a display panel including pixels, a gate driver outputting gate signals to the pixels, a data driver outputting data voltages to the pixels, a sensing circuit receiving sensed signals from the pixels, a power voltage generator applying a power voltage, and a driving controller for stopping the display panel, the gate driver, the data driver, and/or the power voltage generator when the display panel is determined to be defective. The driving controller selects a first-mode threshold set or a second-mode threshold set based on an initial value set related to the sensed signals for determining whether the display panel is defective. Thresholds in the first-mode threshold set respectively correspond to and are respectively unequal to thresholds in the second-mode threshold set.
