Abstract
An assistant PC LCD display screen with a cursor lockable small screen is provided. A multi-functional and rotary small display screen is secured on the top edge of a desktop PC keyboard, so that the user can view the small screen directly without raising his/her head when the user manipulates the keys. The utility model solves the problem of fatigable, erroneous, and inefficient work in mass data input, accurate data input, and verification for users who are incapable of ''touch type'' and works embarking on statistics, accountant, and market analysis jobs. The assistant PC LCD display screen provides separate display of calculator or video content, etc., and is favorable for working and can alleviate fatigue. The assistant display screen can be upgraded or expanded at any time. The cursor locking technique makes the editing work on the small screen very convenient. The user can edit in full screen or display an enlarged image of the content around the cursor on the main screen. With the ''multi-window'' function provided by the system, the assistant display screen can display associated documents or auxiliary tools different to the content on the main screen, so as to facilitate comparison, reference and transcription between documents. The utility model can improve the working efficiency greatly and is economical and practical.
Description
Affiliated technical field:
The utility model relates to a kind of computer peripheral, both has been installed on small-sized, multi-usage, the lockable computing machine liquid crystal of cursor auxiliary display screen on the desktop computer keyboards.
Background technology:
Though the known main frame of computer market can drive many display screens simultaneously, main frame output be single display mode, main and auxiliaryly help display screen (claim: former machine display screen be a main display, and other display screens are auxiliary display screen.Down together) shown window, form, content are identical.Since shown amount of bytes big and dwindle after visibility poor, be difficult to realize the miniaturization of auxiliary display screen;
During computer operation, often have access to the relevance file continually, or use subsidiary function (as: the long counter of opening, video etc.) at any time.And under present all synchro display mode, no matter whether use auxiliary display screen, can only be on same display screen continuous mapping window, very inconvenient;
Though Windows operating system provides " magnifier " annex at present, though have the tracking editting function.But in order to put " magnifier ", the shown document file page of window is reduced.The result is: the space of a whole page is crowded, poor visual effect.Problem was then more outstanding when the small screen showed.
Summary of the invention:
The purpose of this utility model provides a kind of cursor lockable formula area of computer aided display screen.Main and auxiliary display screen can be synchronously, also can show different document respectively.
Under display mode respectively, the part of the cursor locking of display screen, main display document is tracked in auxiliary display screen, be exaggerated, the main and auxiliary display screen of computing machine is complete to show the inconvenience that causes synchronously to overcome.Also make auxiliary display screen can dwindle area significantly.
In the documents editing process, cursor is locked in appointed position, a place in the auxiliary display screen curtain always.During characters such as (one group) word of every typing, speech, numeral, display screen brush screen, the character reach, cursor visual geometric position in auxiliary display screen is motionless, has avoided cursor to move about and seeks the inconvenience that cursor, adjustment cursor position bring.
The utility model is installed on the coboundary of desktop computer keyboards, by " split screen device " and the shared display adapter of main display (video card).Can significantly improve documents editing efficient, improve visual fatigue.
When multi-display showed, " magnifier " difference that this function and known Windows operating system provide is: main and auxiliary display screen can show different document respectively.
As option, but yet full screen display of auxiliary display screen, cursor are not locked.Make main display, auxiliary display screen show different associated withs or aid respectively, very convenient.
The technical scheme that its technical matters that solves the utility model adopts is:
One, augments, revises computer source program and set up corresponding routine, registration table, order set etc.Content objective is:
(1), sets up the source program pattern that main and auxiliary demonstration output shows respectively.
1, when main and auxiliary display screen shows same document:
(1), the main output default setting that shows is: startup " magnifier " function also minimizes; " magnifier " function setting is " following mouse pointer " and " following the copy editor ";
(2), the auxiliary output default setting that shows is: " magnifier " function and maximization, full screen display; But lock behind the assigned address.By USB interface to the main frame input instruction.
2, when main and auxiliary display screen shows different document:
(1), demonstration is output as normal displaying mode respectively;
(2), when auxiliary demonstration output default setting is " showing synchronously with main display ", shows dialog box prompting selection by basic display unit, or select " cursor locking " (seeing below) by the auxiliary display screen options button.
(2), auxiliary apparent setting of not shielding:
Except that the display function key of standard, set up: the cursor position key is cursor lock definiteness allocation, and imports " message " such as assigned address, conversion windows by USB interface to CPU.
Two, increase when repairing source program uncommitted, as interim measure, can be by other high-level [computers design forms such as C++, interface, and with the content dynamic link of the Word document of main display operation, Excel document to the window of language such as C++ establishment.Wherein:
(1), the document of window shows that the option default setting is: " single file left-justify demonstration " pattern.Realize the amplification of the fixing and single file of cursor.
(2), when main and auxiliary display screen shows different document, the multiwindow tiling function of using Windows to provide, different document, window that main and auxiliary display screen will be shown tile, by high-level [computer two windows of two parts of documents are distinguished default settings again and be maximization, both: main and auxiliary display screen is hidden one of them window after the tiling respectively, another window of full screen display is finished demonstration respectively.Main display dialog box or auxiliary display screen options button are controlled.
With the foregoing is the target coding, and sets up corresponding class library function, Dynamic Link Library Function, multiple document interface and be provided with etc.
Three, as one of multiselect item of supporting technology scheme, can adopt mode to corresponding program, HardwareUpgring in the video card, in video card, press above-mentioned target, CPU is flowed in the data stream of video card that the cursor control code is separated, revised, upgrading, realize locking, do not lock dual mode, be respectively applied for main and auxiliary display screen.The same, discern, selected by auxiliary display screen;
Four, as one of multiselect item of supporting technology scheme, also cursor control code in the video card data stream can be separated, revised, solidify the back as individual devices, post and be loaded within split screen device or the auxiliary display screen.
This screen is designed to can 90 ° of rotations, but accumbency or vertical type clamp.Both: document can horizontal, vertical two kinds of display modes show.Because screen is little, the word table of some character input method shows the problem that goes out screen when long to solve.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1: when adopting software to support, computing machine and peripherals and auxiliary display screen continue and concern synoptic diagram
Fig. 2: adopt video card upgrading or increase curing device to continue and concern synoptic diagram with the hardware mode that locks cursor
