Description

A kind of display type keyboard of portable computer

Technical field

The present invention relates to a kind of keyboard structure of portable computer, be specifically related to a kind of touch-screen and flat-panel screens structure and method as portable computer keyboard.

Background technology

Portable computer comprises concrete forms such as notebook computer, the super mobile computer of hand-held, and the input media that it is main---keyboard adopts mechanical type for a long time always, only can composition notebook typing work.In portable use, the mechanical keyboard of this type of simple function has been monopolized whole man-machine interaction breadth, and the space resources utilization is extremely unreasonable.

With regard to development trend, portable computer just develops towards the thin direction of ultralight, its original display screen (primary display screen) can't be done too greatly, be difficult to satisfy slip-stick artist's coding or picture need of work, in general, if integrated 2 display screens of notebook then can satisfy slip-stick artist's work requirements preferably, while make it can check that drawing does figure or coding.

At present some portable computers are furnished with touch-screen, can use screen soft keyboard input thereon, but this screen soft keyboard is positioned on the primary display screen, and appearance forrns is single uninteresting, only arranges out qwerty keyboard with the form of 2D.

Summary of the invention

In order to overcome the deficiency of above-mentioned portable computer conventional keyboard, promote the space availability ratio of man-machine interaction breadth, the present invention proposes a kind of display type keyboard of portable computer.

The technical solution adopted in the present invention is: propose a kind of display type keyboard of portable computer, be made of keyboard display screen, keyboard touch-screen, internal circuit and interface.The keyboard touch screen layer is stacked on the keyboard display screen, be positioned at the traditional mechanical keyboard planimetric position of portable computer, and be connected with interface with the notebook computer internal circuit, when computer enables, show 2D or 3D keyboard figure by the keyboard display screen, import by finger manipulation keyboard touch-screen.Folding angle between keyboard display screen and the primary display screen can change between 0 to 360 degree, two display screens can be expanded or clone relation and be shown, when two display screens become the expansion demonstration to concern, and can be with the edge-on placement of notebook computer, only make double-display screen and use external mouse-keyboard.When two display screens become clone's demonstration to concern, the double screen display surface can be converted into the above folding angle of 180 degree, be placed on the desktop to erect the isoceles triangle form, watch from front and back simultaneously for a plurality of users.

Described keyboard display screen and primary display screen, can adopt LCDs or organic light-emitting diode (OLED) display screen, also stackable primary touch-screen on the primary display screen, described keyboard touch-screen and primary touch-screen can adopt multi-layer capacity type touch-screen, or multilayer resistor-type touch-screen, support two to eightfold touch control.

Described internal circuit and interface comprise CPU, north bridge chips, graphic presentation chip, figure bridging chip, South Bridge chip, IO chip, embedded controller chip, BIOS chip and two VESA interfaces, and this VESA interface specifically can be one or both in LVDS interface, VGA interface, HDMI interface, the DVI interface.

Show the software switch icon on the described keyboard display screen, be furnished with hardware switch near the screen, the user can adjust enabling or displaying contents of display type keyboard by software switch under S0, S3 state, also can under S0, S3, S4, S5 state, adjust enabling or displaying contents of display type keyboard by hardware switch, the keyboard display screen can be shown as the keyboard of 2D or 3D, or other text, image, graph data.

When described keyboard display screen touches the text input the user, can remedy the feedback disappearance that no mechanical button sense of touch is brought by variable color, distortion, the sound feedback effect of button display interface, and can attach one deck flexible clear materials on its surface to relax the keystroke sense of touch.

Described BIOS chip internal is integrated with the VGA BIOS driver module of keyboard display screen, it shows that mode of operation can be text interface pattern or graphical interfaces pattern, start shooting to entering operating system between the stage videotex information or keyboard figure on display type keyboard by BIOS chip internal program module and VGA BIOS driver module at this notebook computer.Described embedded controller chip internal is integrated with the keyboard touch-screen and drives and the encoding and decoding program module, is responsible for the keyboard touch-screen is carried out turntable driving and keyboard-coding detection after start.

The invention has the beneficial effects as follows: a kind of display type keyboard of portable computer that is proposed, possess the dual-use function of keyboard and display screen, can improve the space availability ratio of the man-machine interaction breadth of portable computer greatly.This display screen keyboard works in two when showing the expansion display mode, display data on one side, show and do figure or encoding software interface on one side, benefit user's need of work.When this display screen keyboard works in the two clone's of showing display mode, can also turn down to erect and place, watch screen simultaneously for the user on two sides, front and back.When this display screen keyboard works in keyboard mode, can show the plane or the three-dimensional keyboard icon of various patterns, mutual effect is more lively.
