ORGANIC LIGHT EMITTING DIODE DISPLAY SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18382319 titled 'ORGANIC LIGHT EMITTING DIODE DISPLAY SYSTEM

Simplified Explanation

The abstract describes an OLED display system that includes a display panel, a driving circuit, a voltage generator, and a power management application circuit (PMAC). The driving circuit provides scan signals to the display panel, while the voltage generator generates a negative voltage based on a first driving voltage with a positive level and a second driving voltage with a negative level. The negative voltage is then provided to the driving circuit. The PMAC consists of a power management application circuit (PMIC) and an additional circuit that is separate from the PMIC and located externally to it. The PMIC applies a high power supply voltage and a low power supply voltage to the display panel and generates the first driving voltage based on a battery voltage. The additional circuit generates the second driving voltage based on the battery voltage. The driving circuit generates at least one of the scan signals based on the negative voltage.

  • The OLED display system includes a display panel, driving circuit, voltage generator, and power management application circuit (PMAC).
  • The driving circuit provides scan signals to the display panel.
  • The voltage generator generates a negative voltage based on a first driving voltage with a positive level and a second driving voltage with a negative level.
  • The PMAC consists of a power management application circuit (PMIC) and an additional circuit located externally to the PMIC.
  • The PMIC applies high and low power supply voltages to the display panel and generates the first driving voltage based on a battery voltage.
  • The additional circuit generates the second driving voltage based on the battery voltage.
  • The driving circuit generates scan signals based on the negative voltage.

Potential Applications:

  • OLED display systems can be used in various electronic devices such as smartphones, tablets, televisions, and wearable devices.
  • The ability to generate scan signals based on a negative voltage can improve the performance and efficiency of OLED displays.

Problems Solved:

  • The OLED display system solves the problem of providing scan signals to the display panel in an efficient and effective manner.
  • The system addresses the challenge of generating a negative voltage for driving the display panel.

Benefits:

  • The use of OLED display systems can result in high-quality and vibrant visual displays.
  • The ability to generate scan signals based on a negative voltage can improve the overall performance and energy efficiency of the display system.
  • The separate power management application circuit allows for better control and management of power supply voltages to the display panel.


Original Abstract Submitted

An OLED display system includes a display panel, a driving circuit, a voltage generator and a power management application circuit (PMAC). The driving circuit provides scan signals to the display panel. The voltage generator generates a negative voltage based on a first driving voltage having a positive level and a second driving voltage having a negative level and provides the negative voltage to the driving circuit. The PMAC includes a power management application circuit (PMIC) and an additional circuit distinct from the PMIC and disposed externally to the PMIC. The PMIC applies a high power supply voltage and a low power supply voltage to the display panel and generates the first driving voltage based on a battery voltage. The additional circuit generates the second driving Voltage based on the battery voltage. The driving circuit generates at least one of the scan signals based on the negative voltage.
