Embodiment Construction

[0032] see figure 1 , figure 1 It is a flow chart of the image display touch control method of the present invention.

[0033] In step S102, a virtual computer desktop image is generated in memory.

[0034] The virtual computer desktop image is generated according to the content actually required to be displayed, and the internal memory is used as a virtual display device, and the virtual computer desktop image is first temporarily stored in the internal memory. The virtual computer desktop image may include various data contents, such as images, windows, text and so on. The virtual computer desktop image is used to output from the internal memory to display on the actual display screen. Since the virtual computer desktop image is stored in the internal memory, and the internal memory generally has a relatively high storage capacity, the virtual computer desktop image may have a relatively high resolution, such as exceeding 100M pixels. Desktop images are generally used in...

Abstract

The invention provides an image display touch control method and a system thereof, wherein the method comprises the following steps: generating a virtual computer desktop image in an internal memory;outputting the virtual computer desktop image to an external display device to display; generating miniature image of the virtual computer desktop image, outputting the miniature image to one displaymodule having a touch sensing function to display, and recording touch operation information for the miniature image; based on a resolution ratio between the virtual computer desktop image and the miniature image, converting the touch operation information for the miniature image into touch operation information for the virtual computer desktop image; and generating new virtual computer desktop image combined with the touch operation information for the virtual computer desktop image. The image display touch control method and a system thereof are capable of realizing touch control for the image display having a high resolution, and are simple to realize with low cost.

Description

technical field [0001] The invention relates to an image display touch control method, and the invention also relates to an image display touch control system. Background technique [0002] With the development of computer technology, the application of touch control technology for display screens has become more and more extensive. The principle of common touch control technology is: install touch detection components directly in front of the display screen, detect touch operation information (including touch point coordinates, time intervals of touch actions, etc.), and then execute on the computer according to the touch operation information. Corresponding processing is performed, and then the execution result is displayed on the display screen. [0003] However, when the resolution of the image to be displayed is relatively large, in order to display a complete image, the resolution of the display screen will be set correspondingly relatively large. For example, in mul...
