DISPLAY DEVICE AND METHOD FOR INSPECTING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18539670 titled 'DISPLAY DEVICE AND METHOD FOR INSPECTING THE SAME
The abstract describes a display device with a gate driver, data driver, power voltage generator, and timing controller to detect misconnections in the device.
- The display device includes a gate driver that outputs signals for writing data voltages and applying initialization voltages to the pixels.
- A data driver is responsible for sending data voltages to the pixels during the misconnection detection period.
- A power voltage generator supplies power to the display panel through a cable during the misconnection detection period.
- The timing controller detects misconnections in the cable based on the power voltage supplied by the power voltage generator.
- The device aims to ensure proper functioning and prevent issues caused by misconnections in the display system.
Potential Applications: - This technology can be used in various display devices such as televisions, monitors, and smartphones. - It can also be applied in industrial settings where reliable display systems are crucial.
Problems Solved: - Detecting misconnections in the display system to prevent malfunctions. - Ensuring the proper functioning of the display device by detecting and addressing cable issues.
Benefits: - Improved reliability and performance of display devices. - Prevention of potential damage caused by misconnections. - Enhanced user experience with seamless display operation.
Commercial Applications: - Display device manufacturers can integrate this technology to enhance the quality and reliability of their products. - Service providers in the electronics industry can use this technology to offer maintenance and repair services for display devices.
Questions about the technology: 1. How does the timing controller detect misconnections in the cable?
- The timing controller detects misconnections by analyzing the power voltage supplied by the power voltage generator.
2. What are the potential implications of misconnections in a display device?
- Misconnections can lead to malfunctions, display errors, and potential damage to the device if not detected and addressed promptly.
Original Abstract Submitted
A display device includes a display panel including pixels, a gate driver configured to output a first gate signal for writing data voltages to the pixels and a second gate signal for applying an initialization voltage to the pixels, which have activation levels, to the pixels in a misconnection detection period, a data driver configured to output the data voltages to the pixels in the misconnection detection period, a power voltage generator electrically connected to the data driver through a cable and configured to output a first power voltage to the display panel in the misconnection detection period, and a timing controller electrically connected to the data driver through the cable and configured to perform a protection operation by detecting misconnection of the cable based on the first power voltage in the misconnection detection period.
