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.
