DISPLAY APPARATUS AND METHOD OF DRIVING DISPLAY PANEL USING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17990130 titled 'DISPLAY APPARATUS AND METHOD OF DRIVING DISPLAY PANEL USING THE SAME

Simplified Explanation

The abstract describes a display apparatus that includes a display panel, a driving controller, and a data driver. The driving controller divides input image data into partial image data corresponding to different display areas of the panel, calculates local loads for each partial image data, determines a scale factor based on the local loads, and applies the scale factor to the input image data to generate a data signal. The data driver converts the data signal to a data voltage and outputs it to the display panel. The scale factor for the center display area is determined differently from the scale factor for the edge display area.

  • The display apparatus includes a display panel, driving controller, and data driver.
  • The driving controller divides input image data into partial image data for different display areas.
  • Local loads corresponding to the partial image data are calculated.
  • A scale factor is determined based on the local loads.
  • The scale factor is applied to the input image data to generate a data signal.
  • The data driver converts the data signal to a data voltage and outputs it to the display panel.
  • The scale factor for the center display area is determined differently from the scale factor for the edge display area.

Potential Applications

This technology can be applied in various display devices, such as televisions, computer monitors, smartphones, and tablets.

Problems Solved

1. Uneven distribution of image data load across different display areas. 2. Inefficient utilization of display panel resources. 3. Inconsistent image quality across the display panel.

Benefits

1. Improved image quality by applying different scale factors based on local loads. 2. Efficient utilization of display panel resources by optimizing the distribution of image data. 3. Consistent image quality across the entire display panel.


Original Abstract Submitted

A display apparatus includes a display panel, a driving controller and a data driver. The driving controller divides input image data into a plurality of partial image data corresponding to a plurality of display areas of the display panel, calculates local loads corresponding to the plurality of partial image data, determines a scale factor based on the local loads, and applies the scale factor to the input image data to generate a data signal. The data driver converts the data signal to a data voltage and outputs the data voltage to the display panel. The scale factor for a center display area corresponding to a center of the display panel among the plurality of display areas is determined differently from the scale factor for an edge display area corresponding to an edge of the display panel among the plurality of display areas.
