Description

Electronic display screen

The utility model relates to image display apparatus, particularly a kind of electronic display.

Desirable display device is be subjected to ambient light when high, can be with an automatic light meter, and in the dark will be luminous automatically, and can at random demonstrate colour, also can go to observe simultaneously, all require to have fine resolution, the response time of existing microsecond level from all angles, keep image in indefinite duration when needed again, have contrast ratio and 64 grades the gray scale and the requirements such as low power consumption of operating on low voltage of 50:1.Although present display device in the world is of a great variety, yet to all reach the display device of above-mentioned technical performance, not come out as yet.Therefore, people have only according to different application requirements and optimization, promptly according to display parameter such as the size of character or figure, marginal bright acutance, contrast ratio, color and forms, also have viewing distance, angle and illumination etc. to observe the selection of reference number.Then to carry out the development of various new display spares on the other hand energetically, in the hope of being able to comparatively desirable display device.

In digitalisation, in the informationalized epoch, information display technology seems and becomes more and more important.Relevant department drops into a large amount of human and material resources and fund Information of Development technique of display both at home and abroad at present.From cathode ray tube (CRT) is that the beginning development is very rapid.Only manage CRT and still be in upward period at present; Still be full of vitality.Yet, because the CRT size is big, heavy, frangible, power consumption is big etc. problem.The appearance of a kind of slab construction, low power consumption, light and handy flat-panel display device, to CRT strong challenge has been proposed, grow up with surprising rapidity, for example: () photoluminescence (ELD), light-emitting diode (LED), vacuum fluorescent display (VFD), plasma (PDP), liquid crystal display (LCD), electrophoresis showed (EPID) and electrochromism (ECD) etc., used widely in departments such as military affairs, industry, communications and transportation.

The purpose of this utility model: be according to the display device specific (special) requirements in the electronic display meter system that is applied in indoor or the operator'ies compartment such as automobile, aviation and locomotive, and be chosen in the compound-material in a kind of III-V main group that visible light is provided in the periodic table of chemical element, as GaP.And directly use it on the inside face of electronic display (8), full content sign Butut according to instrument demonstration in the operator's compartment, be that the good various figures of cloth, character and lines etc. are formed on the inside face of electronic display (8), and after it adds scattering film, can obtain the former effect of face light.To solve above-mentioned specific (special) requirements.

In order to realize this purpose, invention scheme of the present utility model is: in Figure of description, Fig. 1 provides the electronic display meter system chart.It changes (4), CPU8031(5 by sensor (1), data acquisition interface (2), specification of signals circuit (3), A/D), display interface (6), display driver (7) and electronic display (8) part institute form.The different analog quantity electric signal that sensor (1) reflected by the decision circuit of host computer control data acquisition interface, take out successively by the electronic switch pointwise, gather by data acquisition interface (2), after the specification of signals circuit (3) of output carries out standard, change (4) circuit to singlechip CPU 8031(5 through A/D again) convert analog quantity to eight road binary digit/bit amounts, read in internal memory, and data are carried out operational analysis, instruct electronic display (8) to show after the judgement again or order control system is controlled.About architectural feature and concrete enforcement of electronic display (8) and Fig. 2, in the Figure of description explanation, described.

Advantage of the present utility model:

Simple for structure: a kind of electronic display (6) is to be used for the electronic display meter system, its selects speed of response is that 50mm luminous electron energy value is at 1.72eV(720nm)≤Eg≤2.28eV(550nm) between, compound-material such as GaP in the periodic table of chemical element in a kind of III-V main group that visible light is provided directly use it on the inside face of electronic display (8), full content sign Butut according to instrument demonstration in the operator's compartment, be the good various figures of cloth, character and lines etc. are formed on the inside face of electronic display (8), and after it adds scattering film, can obtain the area source effect.Solved the specific (special) requirements of the display device in the electronic display meter system that is applied in indoor or the operator'ies compartment such as automobile, aviation and locomotive.Have that speed of response is fast, clear image, wish that the rink corner is big, polychrome, resolution height, drive simple, low pressure low power consumption, the life-span is long, easy to use, cost is low and characteristics such as easy to implement.

Below in conjunction with Figure of description, the utility model is done further to implement to describe.

Fig. 1 provides the electronic display meter system chart.It changes (4), CPU8031(5 by sensor (1), data acquisition interface (2), specification of signals circuit (3), A/D), display interface (6), display driver (7) and electronic display (8) part institute form.Wherein select the compound-material in a kind of III-V main group that visible light is provided in the periodic table of chemical element on read-out (8) inside face, as GaP, directly with it on the inside face of electronic display according to operator's compartment in the full content sign Butut that shows of instrument, be that the good various figures of cloth, character and lines etc. are formed on the inside face of electronic display (8), as shown in Figures 2 and 3.For fear of the degeneration of compound-material, reduce reflection and sorption and obtain than the uniform surface light source effect, will be with the inside face of the packaged electronic display of one deck scattering film (8).Scattering film is to select materials such as bead formula or vesicular film for use.

The full content sign schematic appearance that shows in the sign schematic appearance of the whole lamps of the electronic display that Fig. 2 provides (8) demonstration and the electronic display meter system, wherein: (9), (10), (12) are the sign of signal lamp, (9), (10) be again that the sign of front and back lamp and (12) be the sign of stoplight stop lamp, (11) are that power supply sign, (13) are warning mark.(14) be water temperature display mark, (23) for oil pressure display mark, (20) for charging or discharging current display mark, (21) for air pressure (air bottle and brake) display mark, (19) for engine speed display mark, (15) be voltage display mark, (16) for turn round about being display mark, (18) of speed of a motor vehicle display mark, (17)) for oil mass display mark, (24) be to dispatch from the factory to add up the milimeter number display mark for milimeter number display mark and (24).

The utility model is applicable to the requirement of the display device in the interior electronic display meter system of operator'ies compartment such as automobile, aviation and locomotive, as require that speed of response is fast, illumination is that 500Lux or the contrast when night still can be greater than 5:1 greater than 1200, in the car for polychrome, field of view angle, distance can be seen picture clearly at 60cm, the low pressure low power consumption, drive simple, the life-span is long, the specific (special) requirements of lightning protection and anti electromagnetic wave interference etc., therefore, the display device of the utility model in a kind of comparatively desirable electronic display meter system that can be called at present in indoor or the operator's compartment.

Promptly constitute the utility model-a kind of electronic display according to above-mentioned making.
