Abstract

The illumination and extinguishing of the background lighting (20) behind the picture screen (14) are controllable in time intervals with such frequency that the required short picture exposure times are obtained. The screen is coupled to a computer (12) which according to a programme generates the pictures for presentation on the screen (14). The control of background lighting illumination and extinguishing occurs via the computer (12). The background lighting (20) is by cold cathode tube or electro-fluorescent plates.

Description

15 20 25 500 370 Det nya arrangemanget lämpar sig väl för uppkoppling av bildskärmen till en dator på konventionellt sätt. Härvid blir det möjligt att generera de för presentation på bildskärmen avsedda bildema via till datom hörande programvara, varvid även styming av bakgrundsbelysningens tändning och släckning kan ske via datom. 15 20 25 500 370 The new arrangement is well suited for connecting the monitor to a computer in a conventional manner. In this way, it becomes possible to generate the images intended for presentation on the screen via software belonging to the computer, whereby control of the backlight on and off can also be controlled via the computer.

Uppfinningen kommer nu att presenteras i form av ett enkelt utföringsexempel under hänvisning till den bifogade ritningen, som upptar endast en figur.The invention will now be presented in the form of a simple embodiment with reference to the accompanying drawing, which takes up only one figure.

Ritningsfiguren visar i förenklad form ett tangentbord 10, som är sammankopplat med en datorenhet 12 jämte därtill hörande bildskärm 14. Bildskärmen 14 visas partiellt i sprängskiss.The drawing shows in simplified form a keyboard 10, which is connected to a computer unit 12 together with the associated display 14. The display 14 is shown partly in an exploded view.

Såsom framgår av ritningsñguren innefattar den till datorenheten 12 kopplade bildskärmen 14 en främre och en bakre huvuddel 16 resp. 18, varvid en belysnings- anordning 20 är placerad däremellan. Belysningsanordningen 20 utgörs i föreliggande fall av två likadana kallkatodrör, vars tändning och släckning är styrbar via datorenheten 12.As can be seen from the drawing, the screen 14 connected to the computer unit 12 comprises a front and a rear main part 16 and 16, respectively. 18, with a lighting device 20 located therebetween. The lighting device 20 in the present case consists of two identical cold cathode tubes, the ignition and extinguishing of which can be controlled via the computer unit 12.

De medelst datorenheten 12 genererade bildema är synliga pä bildskärmen 14, som är av flytkristalltyp, varvid kallkatodrören sålunda på i och fór sig känt sätt är belägna bakom bildskärmen 14 för ästadkommande av avsedd bakgrundsbelysning. Ett ljusfilter 22 är placerat mellan de båda kallkatodrören och bildskännen 14. Härigenom erhålles en likformig lj usfördelning över hela skärmen. Genom tändning och släckning av kallkatodrören erhålls följaktligen den önskade bildpresentationsfrekvensen. Bildema presenteras under korta bildexponeringstider och med önskade tidsluckor. Allt styrs med hjälp av datorn, varvid det är möjligt att utnyttja både programvara och tangentbord enligt önskan.The images generated by the computer unit 12 are visible on the screen 14, which is of the liquid crystal type, the cold cathode tubes thus being located in a manner known per se behind the screen 14 to provide the intended backlight. A light filter 22 is placed between the two cold cathode tubes and the display bar 14. This results in a uniform light distribution over the entire screen. Consequently, by switching the cold cathode tubes on and off, the desired image presentation frequency is obtained. The images are presented during short image exposure times and with desired time slots. Everything is controlled with the help of the computer, whereby it is possible to use both software and keyboard as desired.

Det år naturligtvis möjligt att använda annan bakgrundsbelysning än kallkatodrör.It is of course possible to use other backlights than cold cathode tubes.

Sålunda kan med fördel också exempelvis fluorescerande plattor utnyttjas.Thus, for example, fluorescent plates, for example, can also be used to advantage.
