Embodiment Construction

[0020] see figure 1 , which is a functional block diagram of the electronic reader 100 according to an embodiment of the present invention. The electronic reader 100 includes a processor 10 , a page turning control unit 20 , a switch unit 30 , a display screen 40 , a memory 50 , an input unit 60 and a register 70 . In this embodiment, the input unit 60 is used to generate corresponding instructions in response to user operations, and the register 70 is a synchronous dynamic random access memory (SDRAM, Synchronous Dynamic Random Access Memory). The memory 50 stores a plurality of documents that can be displayed by the e-reader 100. When the e-reader 100 enters a reading mode in response to a user clicking to open a document, the processor 10 changes the page content of the set page range from After being retrieved from the memory 50, it is stored in the register 70, and a signal is transmitted to the page turning control unit 20, and then enters a sleep mode to save power.

Abstract

The invention relates to an electronic reader which comprises a processor, a display screen, a page turning control unit, a switching unit and a buffering memory, wherein the switching unit is used for switching on the connection of the processor or the page turning control unit with the display screen and the buffering memory; the processor responses to a user operation of opening a file and display the file on the display screen; the page content in a set page range is memorized in the buffering memory; the processor also controls the switching unit to the connection between the page turning control unit and the display screen and the connection between the page turning control unit and the buffering memory, and the processor automatically enters a sleep mode; and the page turning control unit receives a page turning command and carries out page turning control. The invention also provides an electricity-saving control method of the electronic reader. Because the processor is in a discontinuous sleep mode and the page turning control unit with relatively less electricity consumption is adopted for receiving and executing the page turning command in place of the processor when the processor is in the sleep mode, thus the electricity energy is saved.

Description

technical field [0001] The invention relates to an electronic reader and a power saving control method thereof. Background technique [0002] When a user uses an existing e-reader to read, usually the processor controls the content to be displayed and stores it in the synchronous dynamic random access memory (SDRAM: Synchronous Dynamic Random Access Memory) of the e-reader. After receiving the signal, the processor retrieves data from the SDRAM and displays the retrieved data content on the electronic paper display screen. Therefore, when the user uses the electronic reader to read, the processor must always be in the working state, so the power consumption is relatively large. Contents of the invention [0003] In view of this, it is necessary to provide a relatively power-saving electronic reader to solve the above problems. [0004] In view of this, it is also necessary to provide a power saving control method for an electronic reader to solve the above problems. [...
