Problems solved by technology

However, the existing electronic devices with GUI often need to refresh the entire display unit when part of the screen changes, and the touch controller needs to scan the entire touch panel to detect whether there is a touch and the position of the touch. The above problems lead to increased power consumption of touch screen electronics

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] see figure 1 , is a functional block diagram of the electronic device 100 in an embodiment of the present invention. The electronic device 100 may be a terminal device such as an electronic reader, a PDA, or a smart phone.

[0025] The electronic device 100 includes a display unit 10 , a display controller 20 , a touch panel 30 , a touch controller 40 , and a processor 50 .

[0026] In this embodiment, the display unit 10 is a steady state display unit, for example, an electronic paper display screen. In other implementation manners, the display unit 10 can be a non-stable display unit, such as a liquid crystal display (liquid crystal display, LCD). In this embodiment, the touch panel 30 is a transparent touch panel, located directly above the display unit 10 , and forms a touch screen together with the display unit 10 .

Abstract

An electronic device comprises a display unit, a display controller, a touch panel, a touch controller and a processor, wherein, the display controller is used for displaying a graphical user interface on the display unit. The electronic device is characterized in that the display unit is divided into at least two areas, and different areas respectively display a function icon with a preset refresh frequency and a user operation frequency; the touch panel is divided into at least two subsidiary touch panels corresponding to at least two areas of the display unit; and the touch controller detects touch positions of each subsidiary touch panel by adopting corresponding inspection frequency according to the user operation frequency of each area of the display unit.

Description

technical field [0001] The present invention relates to an electronic device with a touch panel. Background technique [0002] Nowadays, all kinds of terminal equipment including mobile phone communication products, computer operating platforms, PDA products, digital products, e-books, etc., all use a Graphical User Interface (GUI) as the operating user interface. [0003] The application of GUI greatly facilitates the use of non-professional users. With the input of the touch panel, people only need to operate through windows, menus, and buttons. However, the existing electronic devices with GUI often need to refresh the entire display unit when part of the screen changes, and the touch controller needs to scan the entire touch panel to detect whether there is a touch and the position of the touch. The above problems lead to increased power consumption of touch screen electronic devices. Contents of the invention [0004] In view of this, it is necessary to provide a mo...
