DATA DRIVER CIRCUIT AND DISPLAY DEVICE HAVING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18463935 titled 'DATA DRIVER CIRCUIT AND DISPLAY DEVICE HAVING THE SAME

Simplified Explanation

The patent application describes a data driving circuit that includes a noise filter, voltage generators, and an output circuit. The circuit is designed to remove noise from a driving voltage and generate reference voltages for outputting a data signal corresponding to an image signal.

  • The circuit includes a noise filter that removes noise from the driving voltage.
  • There are three voltage generators: the first one outputs three different voltages, the second one generates a first reference voltage based on the filtered driving voltage and the first and second voltages, and the third one generates a second reference voltage based on the filtered driving voltage and the second and third voltages.
  • The output circuit uses the first and second reference voltages to output a data signal with a voltage level corresponding to an image signal.

Potential Applications

  • This data driving circuit can be used in various electronic devices that require accurate and noise-free data signals, such as display panels, cameras, and sensors.
  • It can be implemented in smartphones, tablets, televisions, monitors, and other display devices to improve the quality and reliability of the displayed images.

Problems Solved

  • The noise filter helps to remove unwanted noise from the driving voltage, ensuring a cleaner and more accurate data signal.
  • The voltage generators generate reference voltages based on the filtered driving voltage and other voltages, which helps in maintaining the integrity and consistency of the data signal.

Benefits

  • The noise filter improves the quality of the data signal by removing noise, resulting in clearer and more accurate images.
  • The voltage generators ensure that the reference voltages are generated based on the filtered driving voltage, which helps in maintaining the reliability and consistency of the data signal.
  • The circuit can be easily integrated into existing electronic devices, providing an efficient and cost-effective solution for improving data signal quality.


Original Abstract Submitted

Disclosed is a data driving circuit including a noise filter, first through third voltage generators, and an output circuit. The noise filter receives a driving voltage and removes noise from the driving voltage to output a filtered driving voltage. The first voltage generator outputs a first voltage, a second voltage, and a third voltage. The second voltage generator generates a first reference voltage based on the filtered driving voltage, the first voltage, and the second voltage. The third voltage generator generates a second reference voltage based on the filtered driving voltage, the second voltage, and the third voltage. The output circuit outputs a data signal of a voltage level corresponding to an image signal based on the first reference voltage and the second reference voltage.
