Abstract

The utility model relates to a computer keyboard with display function, which belongs to the external device of a computer. The computer keyboard with display function comprises character keys, function keys, additional keys and an additional display. The additional display device is positioned at the front end of an existing computer keyboard and is positioned on the same plane with the keyboard; the length of the additional display is equal to the length of the screen of the display prepared for the computer, and is exclusively used to display the information of current line and status line. The utility model just need to be improved on the basis of existing computer keyboards, the computer keyboard with display function can effectively overcome the hands and eyes matched difficulty during the information input of the computer, and can decrease error rate and enhance the input speed of characters. The computer keyboard with display function is in particular suitable for the computer processing of Chinese character information.

Description

Computer keyboard with display function

The utility model belongs to the computer external unit.

Keyboard is an external input device the most frequently used in the computer hardware system.Domestic employed computor-keyboard follows external import style basically now.If the operator is without long training, then trick cooperates and will compare difficulty, and the operator will cause loading error because of being easy to that useless labor takes place, and particularly when using computer to handle Chinese character information, this situation is particularly general.

The purpose of this utility model is traditional keyboard is improved, and designs a kind of computor-keyboard with Presentation Function, makes it to be more suitable for Chinese character information processing.

Main points of the present utility model are to increase an additional display on the basis of common computer keyboard, additional display and Computer key all are in same plane, utilize the current line and the statusline of additional display display screen, the operation of operator's hand and the observation of eye can organically be taken into account, thereby the purpose of this utility model is achieved.

Below in conjunction with accompanying drawing the utility model is further described:

The utility model comprises button commonly used and additional display ［ 1 ］ such as character keys, function key, additional key, and described additional display ［ 1 ］ is in the same plane with keyboard disk ［ 2 ］, and is positioned at the front end of keyboard.The length of additional display ［ 1 ］ can be laterally isometric with the regular display screen, its vertical width should guarantee to show two line characters, the current line of the first row display screen information wherein, the statusline of the second row display screen information, the information that bottom line shows on the screen in the promptly common hanzi system about duty.For simplifying the computer hardware system, the utility model is designed to the liquid crystal monochrome display with additional display ［ 1 ］ simultaneously.Like this, just only need in the hardware circuit of common computer keyboard, to increase the liquid crystal display signal processing logic, a small amount of integrated circuit (IC) chip such as display driver and LCD or device, in the monochromatic character display adapter of host computer or color character graphic presentation adapter, increase row address decoding, analog-driven switch chip etc.The utility model is connected with the signal of host computer, can adopt serial output mode, therefore only needs to get final product than transmission line of line increase of common computer keyboard and host computer.For example the original 5 core cable connection of using of Chang Yong 101 keyboards and host computer now change 6 core cable connection into.

Adopt the utility model to replace the common computer keyboard, following advantage is arranged: when 1. giving computer from keyboard input information, people's eyesight main attention current line, if input Chinese character, then to take into account statusline, the utility model concentrates on this two row information on the additional display ［ 1 ］, is conducive to the user to showing the supervision of information, reduces errors. 2. as advantage 1. as described in, the utility model can alleviate user's asthenopia. 3. people are when the common computer keyboard operates, the operating position of hand and eyes to watch the position attentively almost vertical. Not at grade, the two is not taken into account and need to training over a long time cultivate. The utility model allows the frequent information of observation that needs with the position device of operation, and is in the same plane, is conducive to user's trick and cooperates, and further reduces operate miss. 4. as advantage 3. as described in, the utility model is conducive to just that upper machine person skillfully grasps keyboard input technology, thereby is conducive to popularizing of computer technology. 5. the utility model is presented at statusline on the additional display ［ 1 ］, thereby it is capable to need not show state on the common display, thereby demonstration has more delegation's information than usual, has enlarged the capacity of display. When 6. operating the utility model, the user mainly watches additional display ［ 1 ］ and keyboard disk ［ 2 ］ attentively, thereby is conducive to reduce the electron radiation of common display to the harm of human eye.

The utility model is changed few to the common computer keyboard, increase cost seldom, goes into operation easily, and very strong commodity competitiveness is arranged.
