As shown in Figure 2, portable computer with two liquid crystal displays and no keyboard of the present invention, a LCD (LCD) module 2 and the main frame module 3 that comprise mutual pivot joint, LCD module 2 has a LCD20, it is second LCD, reaching main frame module 3 and also be provided with a LCD30 at relative LCD20 face, is first LCD.That is, computer of the present invention comprises first and second LCD LCD30, LCD20 and a switching device shifter 4 (figure does not show) that is connected, and switching device shifter 4 is that first and second LCD LCD30, LCD20 can be switched between general modfel and reading model; In general modfel, the first LCD LCD30 is a touch simulating keyboard, and the second LCD LCD20 is a display screen, and in reading model, first and second LCD LCD30, LCD20 are display screen.
When computation of the present invention during in general modfel, the LCD20 of LCD module 2 is a horizontal type display screen, the LCD30 of main frame module 3 then shows a touch simulating keyboard 300, and the user just can reach the mode of importing as the keyboard of portable computer with touch simulating keyboard 300 and operate.
Switching device shifter 4 is located at LCD module 2 or main frame module 3 inside (figure does not show), and its interlock circuit calcspar as shown in Figure 3, switching device shifter 4 comprises a pair of display controller (dualview/displaycontroller) 40, SiliconMotion for example, Inc. SM810 of Sheng Chaning and SM811IC, have two digital video clip,, be electrically connected on LCD20 and LCD30 respectively for first and second digital video interface.One CPU (central processing unit) 42 is electrically connected on two display controllers 40, and CPU42 also is electrically connected on a storage device 44, and also being electrically connected to a LCD30 and a voice device 48 respectively by an I/O treating apparatus 46, voice device 48 converts the analog voice signal of input to CPU42 receptible audio digital signals.
CPU42 can be with the video signal vision signal of output, the video signal vision signal of two display controller 40 acquisition central processor CPUs 42 outputs, be presented at LCD20 and/or LCD30 respectively through the control of two display controllers 40, and has a control program in the CPU42 at least, and the operating process of control program as shown in Figure 4, at first CPU42 can produce a touch button area 420, I/O treating apparatus 46 through Fig. 3, be presented on the LCD30, touch button area 420 comprises that at least one can produce the model selection button area of mode select signal, and the model selection button area comprises a general modfel button and a reading model button.
Then, CPU42 detects touch button area 420 at any time, if the general modfel button is pressed, then makes the computation of computation such as general modfel, and if the reading model button is pressed, then makes computation at reading model.And, CPU42 also can detect the voice signal from 48 inputs of the voice device among Fig. 3, if be the voice signal that an expression switches to general modfel, then makes computation in general modfel, if and be that an expression switches to the voice signal of reading model, then make computation at reading model.
Fig. 5 is the alternate embodiment of Fig. 4, in this alternate embodiment, CPU42 at first sets computation in general modfel (or reading model), produce a touch button area 420 ' then, I/O treating apparatus 46 through Fig. 3, be presented at LCD30, touch button area 420 ' comprises a switching push button at least.Switching push button is equally also in the model selection button area.
Then, whether the switching push button that CPU42 detects touch button area 420 ' at any time is pressed, if, then make computation in reading model (or general modfel), just switch to reading model from general modfel, or switch to general modfel from reading model, and, CPU42 also can detect the voice signal from 48 inputs of the voice device among Fig. 3, if the voice signal of an expression switch mode, in like manner, then computer will switch to reading model from general modfel, or switch to general modfel from reading model.
When computation during in general modfel, promptly through two display controllers 40, set LCD30 is a touch simulating keyboard to CPU42, and LCD20 is a horizontal type display screen.And when computation during at reading model, CPU42 is then through two display controllers 40, sets LCD20 and LCD30 all for behind the formula display screen always, and CPU42 can produce the touch button 422 that skips, through the I/O treating apparatus 46 of Fig. 3, and be presented at LCD30 (as shown in Figure 6).
As shown in Figure 6, when the state of computer work of the present invention at reading model, the user can be by networking tie line 5 or via the storage device 44 of Fig. 3, tell certain two pages or other data of an e-book by CPU42, be presented at LCD20 and LCD30 respectively, because of LCD20 and LCD30 can be used for showing respectively different data or carry out different programs, and when it is used for reading an e-book, LCD30 can show the i page or leaf of e-book, and LCD20 can show the i+1 page or leaf of e-book, and, CPU42 skips button 422 when being pressed when detecting touch, LCD30 can be converted to the i+2 page or leaf that shows e-book, reach and convert LCD20 to show e-book i+3 page or leaf, just as reading books.
In addition, I/O treating apparatus 46 also can be used to be electrically connected CPU42 and LCD20 (figure does not show), make touch button area 420,420 ' or the touch button 422 that skips be presented on the LCD20.
In sum, portable computer with two liquid crystal displays and no keyboard of the present invention has to increase and reads comfortableness and add The advantage of big windows area.
