Mobile communication device and method for switching keyboard functions and displayed pictures

Abstract

The invention relates to a mobile communication device and a method for switching keyboard functions and displayed pictures. The mobile communication device comprises a display, a display controlling unit, a key board, a light source unit, a direction sensing unit and a central processing unit, wherein the keyboard comprises a plurality of keys; the surfaces of each keys are provided with first key symbols and second key symbols; the light source unit comprises a first light source and a second light source; when the direction sensing unit senses that the mobile communication device is in a first direction, the central processing unit controls the light source unit to provide the first light source and makes the keyboard correspond to a first keyboard mode, and allows the display to display a picture in the first direction; and when the direction sensing unit senses that the mobile communication device is in a second direction, the central processing unit controls the light source unit to provide the second light source, makes the keyboard correspond to a second keyboard mode and allows the display to display a picture in the same direction as the second direction, wherein the difference between the first direction and the second direction is 180 DEG or 90 DEG. By taking advantage of the different use directions of the mobile communication device, the invention can easily switch the keyboard use modes, and is convenient for the user to input letters with one hand holding the mobile communication device.

Description

technical field [0001] The present invention relates to a mobile communication device and a method for switching keyboard functions and display screens thereof, in particular to a mobile communication device capable of changing the use position of the keyboard and switching the keyboard function of the mobile communication device according to the use direction of the mobile communication device and how to display the screen. Background technique [0002] see figure 1 As shown, it is a schematic diagram of holding a traditional mobile phone with a hand. Users are often used to inputting characters with the keyboard 10 of the mobile phone 1 to send text messages or store data. , so that when the user holds the mobile phone while inputting text through the keyboard, in order to allow the thumb to press the keyboard smoothly, the user must allow the palm to be held on the lower half of the mobile phone 1 and cannot fully grasp the mobile phone 1, or In the case of fully grasp...

Problems solved by technology

Users are often used to inputting characters with the keyboard 10 of the mobile phone 1 to send text messages or store data. , so that when the user holds the mobile phone while inputting text through the keyboard, in order to allow the thumb to press the keyboard smoothly, the user must allow the palm to be held on the lower half of the mobile phone 1 and cannot fully grasp the mobile phone 1, or In the case of fully grasping the mobile phone 1 with the palm of the hand, it is necessary to move the thumb down to successfully press all the keys on the keyboard, which makes the actual input operation of the mobile phone 1 inconvenient and brings users poor keyboard operation experience

[0003] This shows that above-mentioned existing mobile communication device and button method obviously still have inconvenience and defect in product structure, button method and use, and urgently need to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
