DISPLAY DEVICE WITH VARIABLE EMISSION LUMINANCE FOR INDIVIDUAL DIVISION AREAS OF BACKLIGHT, CONTROL METHOD OF A DISPLAY DEVICE, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18358319 titled 'DISPLAY DEVICE WITH VARIABLE EMISSION LUMINANCE FOR INDIVIDUAL DIVISION AREAS OF BACKLIGHT, CONTROL METHOD OF A DISPLAY DEVICE, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
Simplified Explanation
The patent application describes a display device with a backlight consisting of multiple division areas and a display panel. The device calculates emission luminance for each division area based on input image data, calculates a correction value to correct the input image data based on the emission luminance, corrects the input image data using the calculated correction value, controls the transmittance of the display panel based on the corrected image data, and controls the light emission of each division area based on the calculated emission luminance. The process of calculating the correction value is divided into multiple partial processes, which are sequentially performed in each subframe period of one frame period of the input image.
- The display device includes a backlight with multiple division areas and a display panel.
- Emission luminance for each division area is calculated based on input image data.
- A correction value is calculated to correct the input image data based on the emission luminance.
- The input image data is corrected using the calculated correction value.

A display device includes a backlight consisting of a plurality of division areas and a display panel. Emission luminance for each division area is calculated based on input image data, a correction value for correcting the input image data is calculated based on the emission luminance, the input image data is corrected based on the calculated correction value, the transmittance of the display panel is controlled based on the corrected image data, and light emission of each division area is controlled based on the calculated emission luminance. One frame period of the input image consists of a plurality of subframe periods, and a process of calculating the correction value for correcting the input image data based on the emission luminance is divided into a plurality of partial processes, which are sequentially performed by executing each partial process in each subframe period.
