COLUMN DRIVER INTEGRATED CIRCUIT FOR LOW-POWER DRIVING AND DEVICES INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17950599 titled 'COLUMN DRIVER INTEGRATED CIRCUIT FOR LOW-POWER DRIVING AND DEVICES INCLUDING THE SAME

Simplified Explanation

The abstract describes a column driver integrated circuit (IC) for a display panel that drives two groups of pixel lines. The IC includes a master gray scale voltage generation circuit and a low-power mode amplifier.

  • The column driver IC is designed to drive a first group of pixel lines connected to a first group of pixels and a second group of pixel lines connected to a second group of pixels in a display panel.
  • The IC includes a master gray scale voltage generation circuit that divides a reference voltage to generate tap voltages.
  • The master gray scale voltage generation circuit also generates a first low-power mode gray scale voltage based on at least one of the tap voltages.
  • The IC also includes a first low-power mode amplifier that drives the first group of pixel lines based on the first low-power mode gray scale voltage.

Potential Applications

  • This technology can be used in various display panels, such as LCD screens, OLED displays, and LED screens.
  • It can be applied in devices like smartphones, tablets, televisions, computer monitors, and other electronic devices with display panels.

Problems Solved

  • The column driver IC addresses the need for efficient driving of pixel lines in a display panel.
  • It solves the problem of reducing power consumption in the driving circuitry.
  • It provides a solution for generating low-power mode gray scale voltages for improved energy efficiency.

Benefits

  • The IC allows for efficient driving of pixel lines in a display panel, resulting in improved image quality.
  • It reduces power consumption, leading to longer battery life in portable devices.
  • The low-power mode gray scale voltage generation circuitry enables energy-efficient operation, reducing overall power consumption.
