Abstract

The invention relates to a touch screen device which comprises a video providing unit and a display unit; the video providing unit is used for providing video images; the display unit is used for displaying video images. The touch screen device also comprises: a touch sensing unit used for sensing the touch movement of a user successively by a certain time interval and generating a corresponding touch signal each time when sensing the touch; a position analyzing unit used for generating a coordinate signal representing the corresponding touched position according to each touch signal; a video processing unit used for regulating the display scale of the image of the area corresponding to the coordinate signal in the display unit; and a regulating button used for turning on and turning off the scale regulating function of the video processing unit. The touch screen device can determine the image display scale by controlling the touch time of a finger. The invention also provides an image display method corresponding to 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 electronic products are equipped with display screens, such as mobile phones, game consoles, etc., for the convenience of operation, many portable electronic products are equipped with touch screens, which brings 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 o...
