Problems solved by technology

Therefore, if the touch area is constantly changing in real time with the position of the touch point, it will bring great inconvenience to reading
[0006] When the electronic ink touch screen is used as the display screen, the above-mentioned real-time zoom-in inconvenience to reading is particularly prominent.

Embodiment Construction

[0045] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] figure 1 is a structural block diagram of a portable electronic device according to a specific embodiment of the present invention.

[0047] see figure 1 The portable electronic device 1 of this specific embodiment includes a touch screen 11, a touch detection and positioning device 12, an enlarged display control device 13, a touch movement detection device 14, and an insertion mark position judgment device 15, and the insertion mark position judgment device 15 further includes a judgment module 151 and refresh module 152 . The touch detection and positioning device 12 is used to detect a contact position in contact with the surface of the touch screen 11 and display an insertion mark at the contact position. The enlarged display control device 13 is used to enlarge the display area where the contact position is located and display ...

Abstract

The invention provides a portable electronic device and a display method thereof, belonging to the field of touch screen display. The portable electronic device provided by the invention comprises a touch screen, a touch detection positioning device, a magnifying display control device, a touch movement detecting device and an insertion tag position judging device. The display method comprises the touch detection positioning process, the amplifying display process, the touch movement detecting process and the insertion tag position judging process. If the insertion tag still stays within the display region of the original touch position, the position of the predetermined amplifying display region is unchanged, and the content in the predetermined amplifying display region is unchanged. If the insertion tag goes beyond the display region of the original touch position, the position of the predetermined amplifying display region is changed, and the content in the predetermined amplifying display region is refreshed. With the portable electronic device and the display method provided by the invention, the accurate positioning of the insertion tag is realized on the touch screen, and meanwhile, the refreshing times and the refreshing area of the amplifying region are greatly reduced.

Description

technical field [0001] The invention relates to the field of touch screen display, in particular to a portable electronic device and a display method thereof. Background technique [0002] When positioning the insertion point on a touch screen, usually only an approximate position can be determined, so multiple touches are often required to accurately position. [0003] Therefore, there is a technology of real-time zooming in on the display content in the touch area to facilitate the user to accurately locate the insertion point. [0004] However, in an application field where the touch screen is simultaneously used as a display screen and the screen refresh rate is low, the "real-time" nature of the above-mentioned real-time magnification and positioning technology is not an advantage, but becomes a burden. [0005] Especially in the world of e-readers, the screen only refreshes when you turn a page or pop up a menu. Therefore, if the touch area constantly changes in real...
