Method and device for displaying screen menu on TV and TV

Abstract

The invention discloses a method and apparatus for displaying a screen menu in a TV, and the TV. The method comprises the following steps: when a screen menu display instruction is received, inhibiting a DMA module to read display data of the screen menu from a frame buffer area of a DDR after a current reading period; and if the display data of the screen menu are completely written in the frame buffer area of the DDR, enabling the DMA module to read the display data of the screen menu from frame buffer area of the DDR. By adoption of the method and apparatus for displaying the screen menu in the TV, and the TV disclosed by the invention, the problem that a user sees a refreshing process of the screen menu is effectively prevented, and thus the display effect of the screen menu is improved.

Description

technical field [0001] The present application relates to the field of displaying screen menus, in particular to a method and device for displaying screen menus on a TV, and the TV. Background technique [0002] In the process of intelligent TV development, on-screen menus have played an important role due to the diversification of their pictures and functions. At the same time, the requirements for displaying on-screen menus on smart TV screens have increased accordingly. [0003] figure 1 , is a structural schematic diagram of a television display system in the prior art. like figure 1 As shown, the TV display system includes a remote control signal receiving module electrically connected to the bus, a flash memory, a processor, a graphics processor, a DDR (Double Data Rate, double-rate synchronous random access memory) memory, a DMA (Direct Memory Access, direct memory Reader) controller and display screen, in which DDR memory allocates frame buffer for screen menu, DM...

AI Technical Summary

Problems solved by technology

[0005] The present application provides a method, device and television equipment for displaying screen menus in a TV, so as to solve the problem that if the processing speed of the processor or the graphics processor is slow, the processor and the graphics processor cannot resolve and process in the DMA read cycle Complete the display data of a frame of screen menu, and send the display data to the frame buffer, causing the DMA module to fail to send the display data to the display within the read cycle, so that the user can see the process of refreshing the screen menu on the display , the problem of reducing the user's use effect
