Problems solved by technology

[0003] At present, TV manufacturers have higher and higher requirements for TV OSD software, and the graphics of TV OSD are becoming more and more complex, which makes the font library of TV OSD larger and larger, and the TV chip can store the font library of TV OSD. Regions have limited capacity, which limits TV manufacturers to develop TVs with more powerful TV OSD software

Embodiment Construction

[0016] Figure 1A ~ 1C It is a schematic diagram of the running result of the TV OSD software displayed on the TV screen when the TV is turned on according to an embodiment of the present invention. The image of the tree displayed on the TV screen 100 among the figures is the TV image signal content 105, Figure 1A Graphics in 110, Figure 1B Graphics in 120, Figure 1C The graphics 130 in are all TV OSD graphics, and these graphics are overlaid on the TV image signal content 105 .

[0017] When the TV is turned on, the TV OSD software starts to run, and the TV OSD graphics change from graphic 110 to graphic 120, and then to graphic 130. From the effect, it seems that the TV image content is gradually displayed like opening a blind, thereby reducing the momentary Show the visual impact of TV image content on human eyes, and achieve the effect of protecting eyesight. When the TV is turned off, similarly, the TV OSD graphics change from graphic 130 to graphic 120, and then to...

Abstract

Method of character pattern information for generating characters in instancy at running time of TV OSD software directly is adopted in the invention. In procedure of running TV OSD software, needed characters can be obtained from TV RAM chip written by character pattern information for generating characters created from TV OSD software directly. Thus TV OSD software does not read character library stored in specific area in TV chip so as to reduce dependence on character library. Advantages are: solving deficient space of ROM area in TV chip, increasing flexibility of space for developing TV OSD software.

Description

Background technique [0001] The invention relates to a TV set, in particular to a TV set with TV On Screen Display (hereinafter referred to as "TV OSD") graphics. [0002] TV OSD is all content displayed on the TV screen except TV program content, and is an important function for TV users. The existing TV OSD software and its font library are solidified in different locations in the read-only memory (ROM) of the TV chip after the development is completed. When the TV OSD software is running, the software reads the font information of characters from the ROM area where the font library is stored. Put it in the random access memory (RAM) of the TV chip, and the characters and the graphics they form are displayed on the TV screen, which is called TV OSD. [0003] At present, TV manufacturers have higher and higher requirements for TV OSD software, and the graphics of TV OSD are becoming more and more complex, which makes the font library of TV OSD larger and larger, and the TV c...
