Display system and method of screen

Abstract

The invention discloses display system and method of a screen, which are used for controlling on screen display (OSD) of a display and correspondingly displaying screen information, wherein the screen information mainly contains graphical information and character information corresponding to the graphical information; the character information is provided with a plurality of rows of display lines which can display a plurality of character strings consisting of individual characters or degree bar charts; aiming at the display of the character strings, a controller captures individual character data prestored in a memory to further form the character strings according to character string codes and individual character codes in a code table, and then displays the character strings from the picture of the display; in addition, the colors of the character strings come from the controller without being memorized in a memory, therefore, necessary individual character data are only memorizedin the memory and used for subsequent different character strings to repeatedly download and use and memory resources cannot be wasted due to fully memorizing the data.

Description

technical field [0001] The invention relates to a screen display system and method, in particular to a screen display system and method capable of greatly saving memory resources. Background technique [0002] The display is the best human-machine output interface. A full-color display needs to be adjusted appropriately for parameters such as contrast, brightness, screen size, screen offset, chromaticity, etc. Generally speaking, it has been pre-adjusted before leaving the factory All right. But in order to allow the user to adjust according to the current situation after leaving the factory, the On Screen Display (OSD) will come in handy at this time. [0003] The screen function display will display the control object and background of the adjustment parameters (hereinafter referred to as screen information) on the screen of the display for the operator to understand the status of the parameter setting, and then perform adjustments by other input devices. [0004] The sc...

Problems solved by technology

[0005] This method has a large amount of data and consumes a lot of memory, which makes the cost structure or response speed of the hardware unfavorable for subsequent commercial competition

Especially for medical monitors, because the cause of disease must be clearly found in the display screen of the X-ray film, a very high resolution is required. The consumption of memory resources is even more considerable

[0006]In addition, if the display needs to be turned, for example, the medical display will turn according to the direction of the X-ray film or editing documents, and the entire screen information will also need to turn accordingly; generally The main requirement is the 90-degree two-way steering. In order to cope with the correct display of the two directions, the traditional method needs to pre-store twice the amount of original data to meet this demand.

In this way, not only the memory resources are excessively wasted, but also the burden on the processor to process data will be increased. It is an uneconomical solution to expand the hardware capacity to meet this demand.
