Problems solved by technology

Due to insufficient bandwidth when transferring huge image data at the interface between the data generator and the display, displaying an image with high resolution based on a large amount of image data cannot be easily realized sometimes because the large amount of image data may not be efficiently transferred from the image to The processing unit (GPU) passed to the display panel to satisfy the need to display image frames with ultra-fast scan rates, causing tearing effects in the displayed image

Embodiment Construction

[0029] The present disclosure will now be described in more detail with reference to the following examples. Note that the following description of some embodiments is presented here for illustration and description purposes only. It is not intended to be exhaustive or limited to the precise form disclosed.

[0030] In the foveal region of the human eye, there is a high density of cones and the best visual acuity. As the cone density decreases from the center to a specific angle, the ability to recognize and perceive decreases accordingly. Therefore, during screen display, the human eye is only sensitive to the foveal field of view, in which a small high-definition (HD) area with high resolution is required, and the peripheral area outside the field of view , which can be rendered in a blurry manner without affecting the true visual effect relative to a human viewer. As the viewer's eyeballs turn, the gaze or gaze point changes greatly on the display screen or display panel...

Abstract

A method of processing image data with reduced transmission bandwidth is provided. The method includes receiving a first data set of images of a first resolution and receiving center coordinates. The method also includes determining a high-definition region centered on the center coordinates, including a region and a boundary. Additionally, the method includes rendering a first data set based on the center coordinates and the region of the high definition zone to obtain a first data subset. Additionally, the method includes rendering the data set compressed from the first data set to obtain a second data subset beyond the boundary. Additionally, the method includes transmitting a second set of image data to the display panel, the second set of image data combining the first subset of data for displaying the first resolution image and the second subset of data for displaying the second resolution image The second data subset of .

Description

technical field [0001] The present invention relates to display technology, and more particularly, to a method and display device for processing image data with reduced transmission bandwidth. Background technique [0002] With the development of virtual reality (VR) imaging technology, the demand for display devices with ultra-high display resolution and ultra-fast scan rate for displaying digital images is gradually increasing. Due to insufficient bandwidth when transferring huge image data at the interface between the data generator and the display, sometimes displaying an image with high resolution based on a large amount of image data cannot be easily achieved because the large amount of image data may not be efficiently extracted from the image The processing unit (GPU) is delivered to the display panel to meet the need to display image frames with ultra-fast scan rates, resulting in tearing effects in the displayed image. SUMMARY OF THE INVENTION [0003] In one as...
