File display system and method thereof
View Patent ↗A file display system is provided. The file display system includes a MCU ( 10 ), a display control unit ( 20 ) and a display unit ( 30 ). The MCU receives power-on commands and power-off commands from a control unit ( 50 ). According to the preferred embodiment, upon receiving a power-off command, the MCU reads a next page data content of a currently displayed page from a storage apparatus ( 40 ) and stores the next page data content in the display control unit; and upon receiving a following power-on command, the MCU enables the display control unit, and the display control unit controls the next page data content stored therein to be displayed on the display unit, the next page data content therefore becomes a currently displayed page. A related method is also provided.
1. A file display system comprising a microcontroller unit (MCU), a display control unit and a display unit, the MCU receiving power-on commands and power-off commands from a control unit, wherein:
upon receiving a power-off command, the MCU reads a next page data content of a currently displayed page from a storage apparatus and stores the next page data content in the display control unit; and
upon receiving a following power-on command, the MCU enables the display control unit, and the display control unit controls the next page data content stored therein to be displayed on the display unit, the next page data content therefore becomes a currently displayed page.
2. The file display system as claimed in claim 1 , wherein the MCU further stores location information of the next page data content in the storage apparatus in the display control unit upon receiving the power-off command.
3. The file display system as claimed in claim 2 , wherein the MCU further obtains the location information on the next page data content from the display control unit, the location information enabling the MCU to flip pages from said currently displayed page.
4. A file display method executed by a file display system comprising a microcontroller unit (MCU), a display controller and a display unit, the method comprising the steps of:
receiving a power-off command;
reading a next page data content of a currently displayed page from a storage apparatus to the display control unit;
shutting off the file display system;
receiving a power-on command; and
enabling the display control system to control the next page data content stored therein to be displayed on the display unit, the next page data content therefore becoming a currently displayed page.
5. The method as claimed in claim 4 , further comprising the step of storing location information on the next page data content in the storage apparatus to the display control unit.
6. The method as claimed in claim 5 , further comprising the step of obtaining the location information on the next page data content from the display control unit, the location information enabling the MCU to flip pages from said currently displayed page.
