DEVICE AND METHOD FOR REDUCING DISPLAY OUTPUT LAG OF TOUCH INPUT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18149304 titled 'DEVICE AND METHOD FOR REDUCING DISPLAY OUTPUT LAG OF TOUCH INPUT

Simplified Explanation

The patent application describes a device and method for reducing the delay in displaying touch inputs on a screen. Here is a simplified explanation of the abstract:

  • The method starts by receiving a touch event as a touch input.
  • It then obtains the input coordinates and touch characteristics of the touch event.
  • Based on this information, it predicts the coordinates of the touch event after at least one frame.
  • It also calculates the output coordinates of an image to be displayed on the screen.
  • Using the input coordinates, predicted coordinates, and touch characteristics, it generates an output image.
  • The method creates a rendering layer in a buffer that is being scanned by the display.
  • Finally, it renders the output image onto the display by placing it on the rendering layer.

Potential applications of this technology:

  • Mobile devices: Reducing display output delay can improve the user experience on smartphones and tablets.
  • Gaming consoles: Minimizing touch input delay can enhance the responsiveness of gaming controllers.
  • Interactive displays: This technology can be used in public displays or kiosks to ensure quick and accurate touch responses.

Problems solved by this technology:

  • Display output delay: The method addresses the issue of delays between touch inputs and their corresponding display outputs, improving the real-time interaction experience.
  • Inaccurate touch responses: By predicting the touch event coordinates, the method aims to provide more accurate touch responses on the display.

Benefits of this technology:

  • Improved user experience: Reducing display output delay enhances the responsiveness of touch inputs, making interactions feel more immediate and natural.
  • Accurate touch responses: By predicting the touch event coordinates, the method aims to minimize any discrepancies between the user's intended input and the displayed output.


Original Abstract Submitted

A device and a method for reducing a display output delay of a touch input are provided. The method includes receiving a touch event as a touch input, obtaining input coordinates corresponding to position coordinates where the touch event occurs and touch characteristics corresponding to touch information of the touch event, based on the touch input, obtaining predicted coordinates of a touch event after at least one frame, based on the input coordinates and the touch characteristics, obtaining output coordinates of an image to be displayed on the display based on the input coordinates and the predicted coordinates, obtaining an output image based on the output coordinates and the touch characteristics, generating a rendering layer in a buffer being scanned by the display, and outputting the output image onto the display by rendering the output image on the rendering layer.
