DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18086762 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes a timing controller, a level shifter, a gate driver, an over-current detector, and a voltage generator. Here is a simplified explanation of the abstract:
- The display device has a timing controller that generates on-clock and off-clock signals.
- A level shifter sequentially generates gate clock signals synchronized with the on-clock and off-clock signals.
- The gate clock signals have a voltage corresponding to a gate driving voltage.
- A gate driver generates gate signals based on the gate clock signals.
- An over-current detector senses the current of each gate clock signal during the on-current detection mode.
- The over-current detector generates a shutdown signal if an over-current is detected.
- A voltage generator provides the gate driving voltage to the level shifter and stops providing it when the shutdown signal is generated.
Potential applications of this technology:
- Display devices such as LCD screens, OLED screens, or LED screens.
- Any device that requires a display, such as smartphones, tablets, televisions, or computer monitors.
Problems solved by this technology:
- Over-current protection: The over-current detector detects excessive current in the gate clock signals and triggers a shutdown to prevent damage to the display device.
- Gate driving voltage control: The voltage generator provides the necessary gate driving voltage to the level shifter, ensuring proper operation of the display device.
Benefits of this technology:
- Enhanced safety: The over-current detector protects the display device from potential damage caused by excessive current.
- Improved reliability: By controlling the gate driving voltage, the technology ensures the proper functioning of the display device, reducing the risk of malfunctions or failures.
Original Abstract Submitted
A display device may include a timing controller which generates on-clock and off-clock signals, a level shifter which sequentially generates gate clock signals each having a rising edge and a falling edge respectively synchronized with a rising edge of the on-clock signal and a falling edge of the off-clock signal, the gate clock signals having a voltage corresponding to a gate driving voltage, a gate driver generating gate signals based on the gate clock signals, an over-current detector detecting an over-current by sensing a current of each of the gate clock signals at a time point when the falling edge of the on-clock signal is generated in an on-current detection mode, and generates a shutdown signal in response to the detected over-current, and a voltage generator providing the gate driving voltage to the level shifter and stops providing the gate driving voltage in response to the generated shutdown signal.
