DISPLAY DEVICE AND LOCAL METHOD OF CONTROLLING LOCAL DIMMING THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18150318 titled 'DISPLAY DEVICE AND LOCAL METHOD OF CONTROLLING LOCAL DIMMING THEREOF

Simplified Explanation

The abstract describes a display device that includes a display panel and a backlight unit with multiple blocks of light emitting diodes (LEDs). The device also has a controller that can adjust the duty ratio and current flowing in a block during a frame cycle based on backlight control information.

  • The display device has a display panel and a backlight unit with multiple blocks of LEDs.
  • A controller is included to adjust the duty ratio and current flowing in a block during a frame cycle.
  • The adjustment is based on backlight control information obtained by the controller.
  • The duty ratio control function is activated when a low current condition is met.

Potential Applications

  • This technology can be used in various display devices such as televisions, computer monitors, and mobile devices.
  • It can improve the efficiency and performance of backlight units in these devices.

Problems Solved

  • The technology addresses the issue of power consumption in display devices.
  • By adjusting the duty ratio and current flowing in the backlight blocks, the device can operate more efficiently and reduce power consumption.

Benefits

  • The technology allows for better control and optimization of backlight units, resulting in improved energy efficiency.
  • It can extend the battery life of mobile devices and reduce electricity costs for larger display devices.
  • The adjustable duty ratio and current control can enhance the overall image quality and brightness of the display.


Original Abstract Submitted

A display device may include a display panel, a backlight unit including a plurality of blocks for providing light to the display panel, each of the plurality of blocks comprising a plurality of light emitting diodes (LEDs), and a controller configured to obtain backlight control information and to activate a duty ratio control function for controlling a duty ratio and current flowing in a block during a cycle of one frame, when a low current condition is satisfied based on the obtained backlight control information.
