BACKLIGHT DRIVING CIRCUIT AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17622781 titled 'BACKLIGHT DRIVING CIRCUIT AND DISPLAY DEVICE

Simplified Explanation

The abstract describes a backlight driving circuit and a display device. The backlight driving circuit consists of a light-emitting unit, a detection module, a power supply chip, and a voltage regulating module. The detection module receives a preset voltage and is connected to a second electrode of the light-emitting unit to output a control voltage. The power supply chip outputs a reference voltage, and the voltage regulating module receives the control voltage and the reference voltage. It is connected to a first electrode of the light-emitting unit and a ground terminal to output a power supply voltage to the first electrode.

  • The circuit includes a detection module that receives a preset voltage and outputs a control voltage.
  • A power supply chip is used to output a reference voltage.
  • The voltage regulating module receives the control voltage and reference voltage to output a power supply voltage to the light-emitting unit.
  • The light-emitting unit is connected to the detection module, power supply chip, and voltage regulating module.

Potential applications of this technology:

  • Display devices such as LCD screens, televisions, and computer monitors.
  • Backlighting systems for automotive displays, aircraft displays, and other transportation applications.
  • Illumination systems for signage, advertising displays, and outdoor screens.

Problems solved by this technology:

  • Efficiently driving the backlight of a display device.
  • Providing a stable power supply voltage to the light-emitting unit.
  • Accurate control of the light output of the display device.

Benefits of this technology:

  • Improved energy efficiency by regulating the power supply voltage.
  • Enhanced display quality with precise control of the backlight.
  • Increased lifespan of the light-emitting unit through optimized voltage regulation.
