The present invention provides a display state switching method and structure of a portable computer, comprising a display screen and its VESA interface, a CPU, a north bridge controller, a south bridge controller, a display chip, a bridge chip, an IO chip, an acceleration sensor, a BIOS chip, and The carrier circuit board constitutes. Wherein, the acceleration sensor is connected with the south bridge controller or the IO chip, and after detecting the side-standing motion state or the placement state of the portable computer, it sends a signal to the south bridge controller or the IO chip, and then under the control of the display core, BIOS or operating system Rotate the screen interface downwards, or switch the displayed content of the screen.
Description
Technical field
The present invention relates to a kind of display status switch method and structure of portable computer, be specifically related to a kind of degree of will speed up sensor application in the edge-on motion detection of computing machine, screen display interface Spin Control, with the method and the structure of double screen content display mode control.
Background technology
Portable computer comprises concrete forms such as notebook computer, the super mobile computer of hand-held, is generally a display screen and the ratio of width to height greater than 1.The double-display screen formula portable computer that substitutes the traditional mechanical keyboard with the display screen keyboard has higher mutual breadth utilization ratio, and it shows that exchange channels can use two screens simultaneously, shows with clone or mode of extension.When showing with mode of extension, this computing machine is edge-on, on one side can check drawing,, can increase work efficiency greatly Yi Bian use developing instrument for the developer.This edge-on use pattern content displayed of following time need be rotated, existing software push buttons control or fuselage hardware button control method all need artificial manually setting, the present invention proposes a kind of acceleration transducer and measures the fuselage laying state, and with this method and structure that control display screen demonstration is rotated and content is switched, more convenient than classic method.
Summary of the invention
The technical solution adopted in the present invention is: the display status switch method and the structure that propose a kind of portable computer, by display screen and VESA interface thereof, CPU, north bridge controller, south bridge controller, display chip, bridging chip, IO chip, acceleration transducer, BIOS chip, and the bearer circuit plate constitutes.Wherein: acceleration transducer links to each other with south bridge controller or IO chip, after detecting the edge-on motion state of portable computer, by GPIO or SMBUS or I2C interface, bridge controller to the south or IO chip send signal, under the control of BIOS or operating system, rotate display screen interface then, or switch the displaying contents of display screen.
Described display screen can be a display screen or two display screens, when being two display screens, wherein a display screen substitutes the traditional mechanical keyboard, it is a kind of touch text input panel, and its display screen can adopt LCDs or organic light-emitting diode (OLED) display screen, adopt multi-layer capacity type touch-screen or multilayer resistor-type touch-screen, support two to eightfold touch control.
The function of described north bridge controller, display chip, bridging chip can integrate, the function of described south bridge controller and IO chip can integrate, and the function of above-mentioned two class chips also can integrate, be independent System on Chip/SoC, described VESA interface comprises one to two LVDS interface, VGA interface, HDMI interface, DVI interface.The inside annexation of above-mentioned device is: CPU links to each other with the north bridge controller, the north bridge controller links to each other with LVDS interface or VGA interface, LVDS interface or VGA interface link to each other with display screen, the north bridge controller also links to each other with the south bridge controller, the south bridge controller links to each other with the IO chip, and the LPC of south bridge controller or spi bus link to each other with the BIOS chip.Above-mentioned annexation also can be CPU and links to each other with System on Chip/SoC, System on Chip/SoC links to each other with LVDS interface or VGA interface, LVDS interface or VGA interface link to each other with display screen, the LPC of System on Chip/SoC or spi bus link to each other with the BIOS chip, the GPIO of System on Chip/SoC or SMBUS or I2C interface link to each other with acceleration transducer, and the BIOS chip links to each other with acceleration transducer.
Described acceleration transducer can adopt two dimension or three-dimensional sensing type, can wrap into the VGABIOS code in the BIOS chip or make it be stored in independent ROM or the FLASH chip.
The edge-on motion state of described portable computer, claim edge-on laying state again, be meant under the portable computer front elevation, when keeping flat, become the motion or the laying state of left surface, right flank, leading flank setting, when above-mentioned edge-on motion takes place, the 3-axis acceleration data that acceleration transducer is gathered will drive the screen view interface and be rotated, and rotation mode can be set to dextrorotation respectively and turn 90 degrees, is rotated counterclockwise 90 degree, clockwise or be rotated counterclockwise 180 degree states.
Described portable computer is as adopting double screen, wherein a screen serves as touch text input panel, then when the computer on-edge motion takes place, the 3-axis acceleration data that acceleration transducer is gathered will drive the screen view content and change, and variation pattern can be set to double screen expansion demonstration or the double screen clone shows.Wherein double screen expansion shows that the single width screen picture that is meant displaing core output fills two display screens simultaneously, two screen display contents general different and common under belong to same graphical interfaces.The double screen clone shows the single width screen picture that refers to displaing core output when filling first display screen, and the clone fills second display screen, and displaying contents is identical with behavior.
The invention has the beneficial effects as follows: the display status switch method of a kind of portable computer that is proposed and structure, can judge the placement state of computing machine automatically, and carry out the screen rotation, the content switching controls benefits the user job needs.
