Display device and display method thereof

#This application is based on and claims priority to the Chinese Patent Application No. 202110164334.2, filed on Feb. 5, 2021 and entitled “DISPLAY DEVICE AND DISPLAY METHOD THEREOF,” the disclosure of which is herein incorporated by reference in its entirety.

#The present disclosure relates to the field of display technologies, and in particular relates to a display device and a display method thereof.

#In some scenarios in the display field, some display devices process images by two processing units. One processing unit is configured to render some interface images and to transmit the interface images to the other processing unit for processing the interface images, for example, superimposing the interface images onto other input images.

#For clearer descriptions of the technical solutions in the present disclosure or the related art, the following briefly introduces the accompanying drawings required for describing the embodiments or the related art. Apparently, the accompanying drawings in the following description only show some embodiments of the present disclosure, and those of ordinary skilled in the art can still derive other drawings from these accompanying drawings without creative efforts.

#FIG. 1 illustrates a schematic diagram of a display system according to some embodiments of the present disclosure;

#FIG. 2 illustrates a schematic diagram of another display system according to some embodiments of the present disclosure;

#For clearer descriptions of the objectives, technical solutions, and advantages of the present disclosure, embodiments of the present disclosure are described in detail hereinafter referring to the accompanying drawings.

#It should be noted that, unless otherwise defined, the technical or scientific terms used in the present disclosure should be given the ordinary meanings as understood by those with ordinary skill in the art to which this disclosure belongs. The terms “first,” “second,” and the like in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. The words “include,” “comprise,” and derivatives thereof mean that the element or item appearing in front of the word covers the element or item listed behind the word and its equivalents, but does not exclude other elements or items. The words “coupled,” “connected,” and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The words “up,” “down,” “left,” “right,” and the like are only used to indicate the relative position relationship. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

#FIG. 1 illustrates a schematic diagram of a display system 100. The display system 100 may be an ultra-high resolution display system. As shown in FIG. 1, the display system 100 includes a system-on-chip (SoC) 102 and a field-programmable gate array (FPGA) 104. In the ultra-high resolution display system 100, the FPGA 104 is typically applicable to image input, output, and processing, the SoC 102 is applicable to rendering the User Interface(UI) of the on-screen-display (OSD) images. An OSD image 106 drawn by the SoC 102 is transmitted to the FPGA 104 through the Low-Voltage Differential Signaling(LVDS) or other video interfaces. The FPGA 104 acquires an output image 110 by superimposing the OSD image 106 onto an input image 108, and then outputs the output image 110 to a display screen (not shown) for display.
