Problems solved by technology

And because the new generation of wide-screen LCD displays are wider left and right, narrower at the top and bottom, and adopt high resolution, the pitch between pixels is narrower than that of ordinary LCD displays, making the fonts displayed exquisite but small, which makes users feel more comfortable. When browsing or editing text, the eyes are easily uncomfortable because the font is too small, which affects browsing files or text editing

Abstract

The invention provides a local display picture magnification method. The method comprises the following steps: defining part of area of the display picture as a magnification area and the other area as a non-magnification area; capturing video data to be displayed in the non-magnification area of the display, and storing the video data into a non-magnification data storage block of a video memorycorresponding to the non-magnification area; capturing video data to be displayed in the magnification area and magnifying the video data, storing the video data into a magnification data storage block of the video memory corresponding to the magnification area; and reading the video data stored in the non-magnification data storage block and the magnification data storage block of the video memory, and sending the video data to the display for displaying.

Description

technical field [0001] The invention relates to a method for displaying a display screen, in particular to a method for partially enlarging a display screen. Background technique [0002] The new generation of notebook computers adopts different liquid crystal display sizes and different resolution methods from existing notebook computers. Most of the liquid crystal display resolutions used in existing notebook computers are 1024×768 pixels, while new notebook computers will use wide-screen displays, such as liquid crystal displays with a resolution of 1600×600 pixels, and provide users with new How to use it. And because the new generation of wide-screen LCD displays are wider left and right, narrower at the top and bottom, and adopt high resolution, the pitch between pixels is narrower than that of ordinary LCD displays, making the fonts displayed exquisite but small, which makes users feel more comfortable. When browsing or editing text, the eyes are easy to feel uncomf...
