Page 5 45415 V. Description of the invention (3) The touch-sensitive analog keyboard 300 can be operated like the keyboard input of a traditional portable computer. A switching device 4 is provided inside the LCD module 2 or the host module 3 (not shown). The relevant circuit block diagram is shown in the third figure, and includes a dual view controller (display controller) 40. For example, The SM810 and SM811 ICs produced by Silicon Motion, Inc. have two digital image interfaces, which are electrically connected to the above LCD 20 and LCD 30 respectively; — 〇Ρϋ 42 'is electrically connected to the above dual display controller 40, and the CPU 42 is more electrically Connected to a storage device 44, and electrically connected to the LCD 20 and a voice device 48 through an input / output processing device 46. The voice device 48 converts the input analog voice signal into a digital voice signal that the CPU 42 can accept. . The CPU 42 will display the output video image signals on the LCD 20 and / or the LCD 30 'under the control of the dual display controller 40, and the CPU 42 has at least one control program, wherein the control program For the operation flow, please refer to the fourth figure. First, the CPU 42 will generate a touch button area 420, which will be displayed on the LCD 30 through the input / output processing device 46 in the third figure. 420 includes at least a general mode button and a reading mode button. Then 'CPU 42 detects the touch button area 42 at any time. If the normal mode button is pressed, the computer is operated in the normal mode; if the reading mode button is pressed, the computer is operated in the reading mode. . In addition, the CPU 42 can also painfully detect the voice signal from the voice device 48 in the third picture. If the voice signal indicates switching to the normal mode, the computer is operated in the general mode; if it is one, it switches to reading. Mode voice signal,

44541 5 V. Description of the invention (4) The brain operates in reading mode. The fifth diagram is a modified embodiment of the fourth diagram. In this modified embodiment, the CPU 42 first sets the computer to operate in the general mode (or reading mode), and then generates a touch-sensitive button area 420 '. The input / output processing device 46 is displayed on the LCD 30 'the touch-sensitive button area 420' includes at least one switch button la. Then the CPU 42 detects the touch button area 420 at any time, whether the switch button is pressed, and if so, causes the computer to operate in the reading mode (or general mode), that is, switches from the general mode to the reading mode, or from the reading mode. The mode is switched to the normal mode. In addition, the CPU 42 can also detect the voice signal input from the voice device 48 in the third figure. If it is a voice signal indicating the switching mode, the computer will switch from the normal mode to the reading mode, or from the reading mode. Switch to normal mode. When the computer is operating in the general mode, the CPU 42 sets the LCD 30 as a touch-sensitive analog keyboard and the LCD 20 as a horizontal display screen via the dual display controller 40; and when the computer is operating in the reading mode When the CPU 42 passes the dual display controller 40 to set the LCD 20 and the LCD 30 to be a straight display screen, the CPU 42 will generate a touch-style page feed button 422, and after the input of the third figure The output processing device 46 is displayed on the LCD 30 as shown in the sixth figure. The sixth figure is a three-dimensional schematic diagram of a preferred embodiment of a keyboardless dual liquid crystal display portable computer operating in a reading mode.
