Problems solved by technology

[0003] However, for the convenience of portability and cost considerations, portable electronic products are small in size and limited in screen area, but display content is varied, so that sometimes a lot of content on the touch screen is too small to be clearly seen, or it is difficult to use The image of the button for touch operation is too small and inconvenient to operate, and sometimes because the proportion of the displayed image is too large, the user needs to view the screen through the up and down and left and right sliding bars, which is very inconvenient to operate

Abstract

A touch screen device comprises a video providing unit for providing a video image and a display unit for displaying the video image; the touch screen device also comprises a touch sensing unit for sensing the touch action of a user and generating a corresponding touch signal; an area analysis unit for calculating the touch area value according to the touch signal; and a video processing unit for regulating the display proportion of the image in the display unit according to the ratio of the touch area value to a preset area value. The user can determine the scaling of the image by controlling the touch area of a finger or other touch control objects on the touch sensing unit, thereby leading the user to control the size of the image at will. The invention also provides an image display method of the touch screen device.

Description

technical field [0001] The invention relates to a display device, in particular to a touch screen device with adjustable image display ratio and an image display method thereof. Background technique [0002] Now, many portable video electronic products, such as mobile phones, PDAs, game consoles, etc., are equipped with touch screens, which bring a lot of convenience to users' operations. Since the touch screen can replace many key operations, many keys can be saved, so that the area of ​​the display screen can be further enlarged by using the touch screen. [0003] However, for the convenience of portability and cost considerations, portable electronic products are small in size and limited in screen area, but display content is varied, so that sometimes a lot of content on the touch screen is too small to be clearly seen, or it is difficult to use The image of the button for touch operation is too small to be inconvenient to operate, and sometimes because the proportion o...
