The method includes: turning on the electronic apparatus to enter a full-screen display mode; switching the full-screen display mode to a block display mode when a mode-switching signal is triggered; and enabling a corresponding operation interface in the block display mode according to an execution state of an operation system of the electronic apparatus in the full-screen display mode and displaying the operation interface in the designated block of the display unit. ## Claims ### Claim 1 An electronic apparatus, comprising: a display unit, having a full-screen display mode and a block display mode, wherein in the full-screen display mode, the whole display unit serves as a displaying frame; in the block display mode, a designated block on the display unit serves as the displaying frame; a switching unit, coupled to the display unit and switching the full-screen display mode to the block display mode according to a mode-switching signal; and a processing unit, coupled to the display unit, wherein upon receiving the mode-switching signal, the processing unit enables a corresponding operation interface according to an execution state of an operation system of the electronic apparatus in the full-screen display mode and displays the operation interface in the designated block, wherein the execution state in the full-screen display mode is an application executing in the full-screen display mode, the operation interface displayed in the designated block corresponds to the application executing in the full-screen display mode, the operation interface is different from an interface of the application executing in the full-screen display mode, a size of the operation interface matches a size of the designated block, the operation interface provides a simple operation function corresponding to the application executing in the full-screen display mode, and the simple operation function is a part of functions provided by the application executing in the full-screen mode. ### Claim 2 (depends on 1) The electronic apparatus as claimed in claim 1, comprising: a first body, comprising the display unit; and a second body, pivoted to the first body and comprising the processing unit and the switching unit; wherein when the second body is parallel to the display unit side of the first body to present a folded state, the second body covers the display unit. ### Claim 3 (depends on 2) The electronic apparatus as claimed in claim 2, wherein the second body further comprises: a sensing element, configured for detecting a relative movement between the second body and the first body; and a judging unit, coupled to the sensing element and the processing unit, wherein when the relative movement is to expose only the designated block of the display unit, the judging unit triggers the mode-switching signal. ### Claim 4 (depends on 3) The electronic apparatus as claimed in claim 3, wherein the sensing element detects a relative position between the second body and the first body, and based on the relative position, the judging unit decides whether to trigger the mode-switching signal. ### Claim 5 (depends on 3) The electronic apparatus as claimed in claim 3, wherein the relative movement is a relative sliding between the second body and the first body. ### Claim 6 (depends on 1) The electronic apparatus as claimed in claim 1, further comprising: a cradle, configured to carry the first body and the second body when the first body and the second body are in the folded state; wherein placing the first body and the second body on the cradle triggers the mode-switching signal. ### Claim 7 (depends on 2) The electronic apparatus as claimed in claim 2, wherein when the first body and the second body are in the folded state, the electronic apparatus enters a hibernation state; wherein when the mode-switching signal is triggered, the electronic apparatus is awaked by the mode-switching signal. ### Claim 8 (depends on 7) The electronic apparatus as claimed in claim 7, wherein before the electronic apparatus enters the hibernation state, the processing unit records the execution state of the operation system in the full-screen display mode. ### Claim 9 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the execution state of the operation system comprises one of a desktop display state, a music playing state and an email browsing state. ### Claim 10 A method for switching a display mode, for an electronic apparatus with a display unit; the method comprising: turning on the electronic apparatus to enter a full-screen display mode, wherein in the full-screen display mode, the whole display unit serves as a displaying frame; switching the full-screen display mode to a block display mode when a mode-switching signal is triggered, wherein in the block display mode, a designated block on the display unit serves as the displaying frame; and in the block display mode, enabling a corresponding operation interface according to an execution state of an operation system of the electronic apparatus in the full-screen display mode and displaying the operation interface in the designated block, wherein the execution state in the full-screen display mode is an application executing in the full-screen display mode, the operation interface displayed in the designated block corresponds to the application executing in the full-screen display mode, the operation interface is different from an interface of the application executing in the full-screen display mode, a size of the operation interface matches a size of the designated block, the operation interface provides a simple operation function corresponding to the application executing in the full-screen display mode, and the simple operation function is a part of functions provided by the application executing in the full-screen mode. ### Claim 11 (depends on 10) The method as claimed in claim 10, wherein after the step of turning on the electronic apparatus to enter the full-screen display mode, the method further comprises: making the electronic apparatus enter a hibernation state when a first body with the display unit and a second body are in a folded state, wherein the electronic apparatus has the first body and the second body, and the folded state is corresponding to that the second body is parallel to the display unit side of the first body and the second body covers the display unit; and awakening the electronic apparatus when the mode-switching signal is triggered. ### Claim 12 (depends on 11) The method as claimed in claim 11, further comprising: recording the execution state of the operation system in the full-screen display mode before the step of making he electronic apparatus enter the hibernation state. ### Claim 13 (depends on 11) The method as claimed in claim 11, wherein when the first body and the second body are in the folded state, the method further comprises: detecting a relative movement between the second body and the first body; and triggering the mode-switching signal when the relative movement is to expose only the designated block of the display unit. ### Claim 14 (depends on 13) The method as claimed in claim 13, wherein the relative movement is a relative sliding between the second body and the first body. ### Claim 15 (depends on 11) The method as claimed in claim 11, wherein when the first body and the second body are in the folded state, the method further comprises: detecting a relative position between the second body and the first body; and deciding whether to trigger the mode-switching signal based on the relative position. ### Claim 16 (depends on 11) The method as claimed in claim 11, wherein when the first body and the second body are in the folded state, the method further comprises: triggering the mode-switching signal when the electronic apparatus is placed on a cradle.
