DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18133998 titled 'DISPLAY DEVICE AND METHOD OF DRIVING THE SAME

Simplified Explanation

The abstract describes a display device that includes a grayscale converter, a data driver, a plurality of pixels, and a current sensor.

• The grayscale converter converts input grayscales into output grayscales using a scale factor.
• The data driver converts the output grayscales into data voltages.
• The pixels receive the data voltages and display an image.
• The current sensor provides a sensing current by sensing the power current supplied to the pixels.
• When the load corresponding to the input grayscales is greater than a minimum load, the grayscale converter adjusts the scale factor based on the difference between a target current and the sensing current.

Potential applications of this technology:

• Display devices such as televisions, computer monitors, and mobile devices.
• Medical imaging devices.
• Automotive displays.

Problems solved by this technology:

• Ensures accurate grayscale conversion and display of images.
• Allows for adjustment of the scale factor based on the load, improving image quality.

Benefits of this technology:

• Improved image quality and accuracy.
• Efficient power management.
• Enhanced user experience.

Original Abstract Submitted

A display device of the disclosure includes a grayscale converter which converts input grayscales into output grayscales based on a scale factor, a data driver which converts the output grayscales into data voltages, a plurality of pixels which receives the data voltages and displays an image based on the data voltages, and a current sensor which provides a sensing current by sensing a first power current supplied to the plurality of pixels to display the image. When a load corresponding to the input grayscales is greater than a minimum load, the grayscale converter adjusts a change amount of the scale factor based on a current difference between a target current corresponding to the load and the sensing current.
