BACKLIGHT APPARATUS AND OPERATING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240127764 titled 'BACKLIGHT APPARATUS AND OPERATING METHOD THEREOF

Simplified Explanation

The abstract describes a patent application for a backlight apparatus that includes a master driving circuit and multiple slave driving circuits in a daisy chain structure to control light emitting elements.

• Master driving circuit generates a transmission frame with training and data periods.
• Slave driving circuits correspond to blocks, receive transmission frame, recover clock, and drive light emitting elements based on data packets.

Potential Applications

The technology can be applied in various display devices such as LCD screens, LED panels, and backlight systems for TVs, monitors, and signage.

Problems Solved

1. Efficient control of light emitting elements in backlight systems. 2. Synchronization of clock signals for accurate display performance.

Benefits

1. Improved display quality with synchronized lighting. 2. Energy efficiency through precise control of light elements. 3. Simplified wiring and connectivity with daisy chain structure.

Potential Commercial Applications

"Backlight Apparatus for Display Devices: Innovations in Light Control Technology"

Possible Prior Art

Prior art may include patents related to backlight control systems, daisy chain configurations for electronic devices, and clock signal recovery in display technologies.

How does this technology impact energy consumption in display devices?

The abstract mentions energy efficiency as a benefit, but specific details on power savings or consumption reduction are not provided.

Are there any limitations to the number of slave driving circuits that can be connected in the daisy chain structure?

The abstract describes a plurality of slave driving circuits, but it does not specify if there is a maximum limit to the number of circuits that can be connected in the chain.

Original Abstract Submitted

in a backlight apparatus, a master driving circuit generates a transmission frame including a training period including a clock training pattern and a data period including a plurality of data packets respectively corresponding to the plurality of blocks. a plurality of slave driving circuits correspond to the plurality of blocks, respectively, and are connected to the master driving circuit in a daisy chain structure. each slave driving circuit receives the transmission frame through the daisy chain structure, recovers a clock based on the clock training pattern, and drives the plurality of light emitting elements included in a corresponding block among the plurality of blocks based on its own data packet among a plurality of data packets.
