Display Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18503452 titled 'Display Device
The patent application describes a display device with a unique gate driving circuit that compensates for variations in voltages to ensure proper pixel operation.
- The display device includes a display panel with a pixel, a gate driving circuit with a stage circuit, a monitoring transistor, a power control unit, and a timing controller.
- The gate driving circuit outputs a gate signal to the pixel based on voltages of Q node and QB node, with the monitoring transistor connected to monitor these voltages.
- The power control unit generates a compensation value based on the monitoring voltage output and provides a compensated driving voltage to the gate driving circuit.
- The timing controller detects abnormalities in the monitoring transistor and controls the output of the compensation value accordingly.
Potential Applications: - This technology can be used in various types of display devices such as LCDs, OLEDs, and microLEDs. - It can improve the performance and reliability of displays in smartphones, tablets, TVs, monitors, and other electronic devices.
