Title: Portable electronic full screen system equipped with computer processing function

Description:
FIELD OF THE INVENTION 
     The present invention relates to a portable electronic full screen system and particularly to a portable electronic full screen system equipped with computer processing function. 
     BACKGROUND OF THE INVENTION 
     To make mobile devices that have a large screen, thin and light, consume less power and can be produced at lower costs to equip with notebook computer capability, or notebook computers to equip with features of mobile devices such as thin and light, energy-saving and lower costs are development directions heavily pursued by the industry in recent years. However, the mobile device equipped with a large screen and also is thin and light and lower cost and consumes less power generally cannot provide computer function to support the commonly adopted platforms of Windows XP, Windows 7 or MAC. The notebook computer capable of executing a large operation system such as Windows XP, Windows 7 or MAC requires a huge amount of resource, thus cannot be made thin and light at a lower cost and energy-saving like the mobile device equipped with a large screen such as iPAD or E-book. These products can be grouped in two types: 1. Mobile devices that are power-saving and portable to facilitate carrying, but not equipped with full personal computer functions such as large storage, PC MS Office, PC Outlook or PC compatibility; 2. Mobile devices compatible with personal computer but are heavier, bulkier, large power-consuming and insufficient power life. The characteristics of these two types of products contradict against each other. How to provide a simple and effective solution that maintains the characteristics of a large screen mobile device of thin and light and power-saving, and also are fully compatible with personal computer is a thorny issue not yet overcome to date. To meet the aforesaid user&#39;s requirements, huge amount of investments and efforts have to be constantly devoted to innovation of hardware manufacturing process to make large screen mobile devices thin and light with a longer power life and also compatible with the personal computer. 
     Moreover, the conventional mobile devices not supporting PC MS Windows or Apple MAC platform mostly do not have a common user and operation interface. That difference in various products requires users more time in understanding and learning, and creates an extra burden to the unskillful users. Nowadays MS Windows or Apple MAC personal computers are the most popular and well-accepted information devices, they need least amount of education and training, and minimum marketing cost, market acceptance is highest and promotion is easiest. 
     SUMMARY OF THE INVENTION 
     The primary object of the present invention is to provide a portable electronic full screen system equipped with comprehensive computer processing function that also includes features such as a large screen, portable, longer power life, thin and light, energy-saving and lower cost. 
     Another object of the present invention is to provide a portable electronic full screen system with a transmission and user interface compatible with the personal computer of PC MS Windows or Apple MAC. 
     To achieve the foregoing objects the portable electronic full screen system according to the present invention includes a portable electronic full screen module and a remote host. The portable electronic full screen module includes a human machine control unit, a first communication unit connecting to the human machine control unit, a full screen simulation unit connecting to the first communication unit, and an output unit connecting to the full screen simulation unit. The human machine control unit receives a control command which is sent through the first communication unit through a public network to the remote host. The remote host receives the control command and performs a corresponding process, then sends processed data through the public network back to the portable electronic full screen module. The first communication unit receives the processed data which is further processed by the full screen simulation unit for a full screen simulation of signals, then is sent to the output unit which outputs a multimedia information. 
     As described above, the present invention enables the portable electronic full screen simulation module which is linked to the remote host via the public network to have comprehensive processing ability in applications. The processed data is delivered through the output unit in a multimedia information fashion and presented on the portable electronic full screen module. Although the portable electronic full screen module is simpler in structure, by linking to the public network it can perform more complicated processes. Moreover, it does not need too many hardware elements and maintains the feature of longer power life for portable device, and also keeps the advantages of thin and light and provides powerful processing ability. In addition, the full screen simulation unit can execute a full screen simulation similar to high definition to support system operation of the remote host. 
     The foregoing, as well as additional objects, features and advantages of the present invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

The human machine control unit  11  is selectively a keyboard, a mouse, a touch control interface, a voice control interface or combinations thereof that allows a user to control input and converts the input to the control command. 
     The remote host  20  receives the control command and performs a corresponding process, then sends processed data through the public network  30  back to the portable electronic full screen module  10 . 
     The first communication unit  12  receives the processed data which is further processed by the full screen simulation unit  16  for full screen simulation of signals, then is sent to the output unit  13  which outputs a multimedia information. The multimedia information can be voice signals, video signals, screen pictures or combinations thereof. The full screen simulation unit  16  performs the full screen simulation of the pictures output from the remote host  20  to enhance application usability. The public network  30  is connected to the first communication unit  12  and a second communication unit  21 . In this embodiment the connection is a wireless network connection, such as Wi-Fi, WiMAX, mobile communication network, Bluetooth communication or infrared communication or the like. 
     In this embodiment the remote host  20  includes the second communication unit  21  to receive the control command through the public network  30 , a control simulation unit  22  connecting to the second communication unit  21 , a central processing unit  23  connecting to the control simulation unit  22  and a signal interception unit  24  connecting to the central processing unit  23  and second communication unit  21 . The control simulation unit  22  receives the control command and simulates the control interface of the human machine control unit  11  to perform a corresponding control to the central processing unit  23 . The signal interception unit  24  intercepts the processed data processed by the central processing unit  23  and sends the processed data to the public network  30  through the second communication unit  21 . 
     Furthermore, the portable electronic full screen module  10  may also be equipped with encryption security function for transmitting the control command through the public network  30  to the remote host  20 . The portable electronic full screen module  10  may include a first encryption unit  14 , and the remote host  20  may include a first decryption unit  25  corresponding to the first encryption unit  14 .

The first communication unit  12  is connected to the output unit  13  through the second decryption unit  15  which decrypts the encrypted processed data before it is sent to the output unit  13 . 
     The portable electronic full screen module  10  may also be attached to a large screen mobile device (not shown in the drawing) which may be an E-book, Smart book, or Net book. A great portion of functions of the portable electronic full screen module  10  are provided by the remote host  20  through the public network  30 , hence hardware requirement can be greatly reduced to meet other requirements such as thin and light, energy-saving and low cost. On the other hand, the conventional non-cell phone large screen mobile device (such as E-book) does not have capability to support MS Windows or Apple MAC platform, hence, in the case of E-book, can only provide reading function; to perform media play requires a hard disk of huge capacity to store files, and also needs chip sets of image processing capability and audio processing capability, as a result, the size increases and the cost is higher, and consumer&#39;s purchase desire is lower. Through the portable electronic full screen module  10  of the present invention, the remote host  20  can be linked to the portable electronic full screen module  10  through the human machine control unit  11  and first communication unit  12  via the public network  30 , and a corresponding control simulation can be performed through the control simulation unit  22  resided on the remote host  20 , and the central processing unit  23  in the remote host  20  can perform corresponding computer processes, such as document process, images and audio process of media playing and the like. Finally the process result can be sent back to the portable electronic full screen module  10  and image and audio can be output through the output unit  13 . Usability improves, computer function is enhanced on the E-book to the PC level, most important, the cost does not increase significantly, and consumer&#39;s purchase desire can be boosted. 
     As a conclusion, the present invention provides the portable electronic full screen module  10  and remote host  20  that are linked via the public network  30 , hence the portable electronic full screen module  10  can get more comprehensive processing ability through the remote host  20  to perform applications; and the processed data can be output in a multimedia information fashion through the output unit  13 . Therefore, some power consuming tasks can be transferred to the remote host  20  for processing, and some existing devices (such as 2.5-inch hard disk or the like) can be dispensed with to reduce the weight and power consumption of the mobile device. Format support issue of the conventional mobile devices (such as E-book) can be standardized through image and audio signal conversion at the remote host  20  and sent back to the portable electronic full screen module  10  through the network without too much hardware. The mobile device can be used for a longer duration and also maintain the advantages of thin and light, lower cost and powerful performance. In addition, through the full screen simulation unit  16  a full screen simulation similar to high definition can be performed to support system operation of the remote host  20 .
