Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The invention provides a method for displaying an ultra-high-definition OSD menu.

[0047] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for displaying an ultra-high-definition OSD menu in the present invention.

[0048] In the first embodiment, the display method of the ultra-high-definition OSD menu includes:

[0049] Step S10, when starting the ultra-high-definition application, allocate processing memory from the video memory of the graphics processor;

[0050] In this embodiment, when an ultra-high-definition application is started, the processing memory is directly allocated from the memory of the Graphics Processing Unit (GPU), that is, the video memory, instead of applying for the processing memory from the system memory, and the processing memory allo...

Abstract

Disclosed is a method for displaying an ultra-high-definition OSD menu, comprising the following steps: when starting an ultra-high-definition application, allocating a processing memory from a video memory of a graphics processing unit; conducting model rendering on a graphic of the ultra-high-definition application by the graphics processing unit in the allocated processing memory to acquire an ultra-high-definition application image layer; and blending and overlapping the ultra-high-definition application image layer with a preset application image layer to acquire a menu image layer, and displaying the menu image layer via an OSD menu. Also disclosed is a device for displaying the ultra-high-definition OSD menu. Since existing hardware platforms have limitations and a bandwidth of a system memory has a bottleneck, the present invention improves a display frame rate of an ultra-high-definition OSD menu, and improves smoothness of user operation and user experience for the ultra-high-definition OSD menu.

Description

technical field [0001] The invention relates to the technical field of menu display, in particular to a method and device for displaying an ultra-high-definition OSD menu. Background technique [0002] With the development of display technology, ultra-high-definition TVs such as 4K2K TVs have gradually entered the mainstream TV market, but most 4K2K TVs can basically only play 4K2K ultra-high-definition videos or pictures, and the OSD (on-screen display , screen menu adjustment method) the menu is still displayed by stretching the resolution of 1080p, which will greatly affect the clarity of the OSD menu display, so that the OSD menu cannot Achieve 4K2K ultra-high-definition resolution visual effects. Although there are 4K2K TVs that can display 4K2K ultra-high-definition resolution OSD menus, the display frame rate of 4K2K TVs when displaying 4K2K ultra-high-definition resolution OSD menus is very low due to limited hardware platforms and bottlenecks in system memory bandw...
