Abstract
The utility model discloses a projection virtual keyboard which comprises a liquid crystal screen, a touch screen frame, a keyboard projection module, a parallel light module and a camera module, wherein the touch screen frame is arranged around the liquid crystal screen, and the parallel light module is arranged in the touch screen frame under the liquid crystal screen; and the camera module and the keyboard projection module are arranged in the touch screen frame above the liquid crystal screen. The projection virtual keyboard has a simple and convenient structure, and the inputting of characters can be quickly realized in the mode of the projection keyboard.
Description
Technical field
The utility model relates to a kind of dummy keyboard, relates in particular to the dummy keyboard that a kind of projection forms.
Background technology
At present, the keyboard of products such as panel computer, mobile phone, MP4, palm PC generally all is to show on liquid crystal display, and finishes corresponding input service by the touch-screen of touch liquid crystal screen top.This mode will constantly touch these equipment when in use, because the area of these product display screens is limited, the keyboard area of demonstration is smaller, and LCD screen is when display keyboard, and the area of other guide has also significantly reduced, and uses very inconvenient.Another mode solves for needing external keyboard in kind, carries and uses all very inconvenient.
Summary of the invention
The purpose of this utility model is that a kind of dummy keyboard of realizing a projection on products such as panel computer, mobile phone, MP4, palm PC is provided at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme:
A kind of projection dummy keyboard comprises liquid crystal display, touch-screen frame, keyboard projection module, directional light module, camera module, is the touch-screen frame around the liquid crystal display, is provided with the directional light module in the touch-screen frame of liquid crystal display below; Be provided with camera module and keyboard projection module in the touch-screen frame of liquid crystal display top.
The light of described directional light module emission can be Infrared, luminous ray or ultraviolet light.
Described camera module is CMOS camera or CCD camera.
The keyboard pattern that the plane parallel light of described directional light module emission and keyboard projection module are launched is parallel and the 1-5 mm distance arranged.
When in use: keyboard projection module on desk or other media project a keyboard pattern, directional light module below liquid crystal display is launched a planar light, this planar light is parallel with keyboard pattern and the 1-5 mm distance arranged, this planar light is for adopting the planar light of specific wavelength, perhaps the planar light of several specific wavelengths combines, at this moment finger can beat literal on keyboard pattern, the camera module picked-up finger that is positioned at liquid crystal display top is reflective planar light, pass through panel computer, mobile phone, MP4, the software filtering algorithm of primary processor or by camera front end or inner the placement and the optical filter of lower, planar light source co-wavelength in the products such as palm PC, filtering environmental light, pass through the location determination algorithm of primary processor again, calculate the position that finger is pressed, finish the input of keyboard character.
The utility model is simple in structure, convenient, can realize the input of literal fast by the mode of projected keyboard.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure 1, liquid crystal display, 2, the touch-screen frame, 3, keyboard projection module, 4, the directional light module, 5, the camera module, 6, keyboard pattern, 7, planar light.
Embodiment
Embodiment 1:
