Mobile electronic device

Abstract

The invention provides a mobile electronic device, comprising a locating pen and a locating module. The locating pen had at least a supersonic converter near the pen point; the locating module has a processing unit, an output communication unit connected with the processing unit and at least two supersonic converters; the supersonic converter is associated with the supersonic converter is the locating pen to supersonically locate the locating pen and send the locating signal; the processing unit processes the locating signal and outputs the position signal of the locating pen through the output communication unit. The mobile electronic device further has a bistable display module; the bistable display module has a display screen drive unit, a bistable display screen connected with the display screen drive unit, an image buffer caching unit and an input communication unit; the input communication unit receives the position signal of the locating pen output by the locating output module and transmits to the display screen drive unit; the display screen drive unit processes the position signal of the locating pen and stores in the image buffer caching unit or displays on the bistable display screen.

Description

Technical field [0001] The invention relates to a mobile electronic device, in particular to a handheld wireless mobile communication device, which uses a handwriting module to display handwritten information on a bistable display screen. Background technique [0002] At present, mobile electronic devices have been widely used in daily life, such as mobile phones, personal digital assistants, multimedia playback devices, handheld satellite navigation devices, and so on. These mobile electronic devices can be controlled through man-machine communication methods such as natural voice, keyboard device, multi-function key or handwriting module. [0003] Since the natural voice is most in line with the habit of human beings to communicate, among these man-machine communication methods, the most convenient one is the natural voice mode of controlling the mobile electronic device by voice commands. However, the human-computer communication method using natural speech is not yet ma...

figure 1 The screen 11' of the mobile electronic device 10' shown is both a display screen and a touch screen. When the user writes directly on the screen with the stylus 12', he can directly input text and images, because the touch screen is a resistor The type touch screen is attached to the display screen, so it cannot be used separately. If the user accidentally damages any screen, it needs to be replaced as a whole, and because the power consumption of the display screen is large, and the backlight board is required to supply the light source, so this Mobile electronic devices need to be charged frequently to maintain usability, and when the power is turned off, the display screen is turned off, so it does not meet the traditional document reading and writing habits of users
