In this type of portable electronic product, it is not a large device, if too much operation is displayed by the display wire, the potential = 曰 consumes a lot of power. For example, when programming, it is often necessary to operate the Nagasaki time, and the display screen should be kept open during this time.曰 and the portable e-book product touches the BTNLCD 'BistableTwistedNematieLCD' The memory characteristics are only updated, no page_power consumption, no power maintenance is required after display, so power can be saved significantly. However, if you frequently update the data, the LCD screen will lose the power saving effect, and it will consume power compared with the general LCD. The bistable LCD screen also has a slow update speed. In addition, we often check the system status information such as time, power, and schedule during the use of portable electronic products. If the main screen of the portable electronic product is always used, the power consumption will be large and the display information will affect each other. Waiting for the situation. SUMMARY OF THE INVENTION _ There is a cloud here, it is necessary to provide a dual screen display device, which can display the system status information in time, and can quickly update the displayed edited face while saving power. The above dual-screen display device also solves the problem that the update speed of the stable liquid crystal display screen is slow when the display screen is mostly a steady-state liquid crystal display screen. It is also necessary to provide a dual screen display method that not only displays system status information in time, but also quickly updates the displayed edited picture while saving power. 6 1310531 The dual screen display device comprises a first display, an editing operation unit and a processing open.谂鯓 _ _ first, 4 no screen, received the edit operation signal generated by the editing operation unit when the data entered in the series is displayed on the second display screen.

The screen, for example, a bistable liquid crystal display screen, a multi-stable liquid crystal display screen SSCT LCD (Surface-Stabilized Cholesterol Texture Liquid Crystal Display), and an electronic ink (E-Ink) display screen. The second display screen 11 is smaller than the first display screen 10 and is an unsteady display screen, for example, Twisted Nematic Liquid Crystal Display (TN).

The second display screen 11 is configured to display the data input during the first display screen 10 when the power is turned off or during the editing operation. The information that needs to be displayed in time may be system status information, such as: time, power, current first Display information such as chapters and page numbers corresponding to the data displayed on the screen. The volatile memory 13 may be a random access memory ram (Rand() m Aeeess Memory)' for temporarily storing data required or generated during operation. The non-volatile memory μ can be a read only memory (ROM) or a flash memory F!ash. In the present embodiment, the operation unit 15 includes an editing operation unit, a confirmation operation unit, and other operation units, such as a query operation unit and the like. When the user operates the unit 15, the corresponding operation signal is generated. The processing unit 12 receives the operation signal ' and performs corresponding processing according to the operation signal. For example, when the operation signal corresponds to the editing operation, the processing list & 12 is displayed on the second display screen u=displaying the edited input data; when the operation is to confirm the operation, the private 12 screen K) is processed and The first display screen 1G is updated to display the edited data, and when the data update on the screen W is finished, the processing unit 12_the first display «other operations, the material 12 is in the second, no operation Operation, for example, when the processing unit is reading the money. Therefore, the borrowing of the money screen device can be used to play the _D-Show screen 1Q Wei, call him _ side can be in the first = thus improving the response speed of the entire device, and greatly saving the power screen , silk - real money type towel double screen shows the flow of the law.
