Abstract
The utility model relates to an electroluminescent luminous device capable of changing a figure for many times, which comprises a display screen 2 which is composed of a plurality of luminous devices 1. The luminous devices 1 can be randomly arranged and are overspread to form the display screen. By using the photoisomerization physical characteristics of the luminous devices, an image is irradiated on each device of the display screen 2 by laser to enable the irradiated parts of the devices 1 to form a synform molecular structure. The brightness is enhanced, and the non-irradiated parts are in an antiform structure; the brightness is weak, and the image is formed by brightness difference; the image is clear without intermittent phenomenon. The utility model is particularly suitable for the images with complex shapes or images which are frequently changed.
Description
The utility model relates to a kind of el light emitting device, particularly a kind of el light emitting device that can repeatedly change figure.
Existing el light emitting device for example display screen arranges that by several luminescent devices interrupted the arrangement forms, its image area partly is made up of different luminescent devices or different electrical wirings with substrate, as Fig. 3 is existing display screen synoptic diagram, 1A forms display screen 2 by several luminescent devices, when electrified light emitting, image area 3 is different with the luminescent device of substrate part 4, so that brightness or the different images that form of color; Or by different mode of connection controls, when for example making image part electrified light emitting, substrate is 4 outages partly, are dark-coloured, and the two luminance brightness difference forms visual.The advantage of this dot matrix arrangement mode is bright and lustrous, color category is more, but on showing, certain shortcoming is arranged, by the display screen that the luminescent device 1A that arranges anyhow constitutes, discontinuous between each device, can be when showing because device is discontinuous, and image is clear inadequately, when particularly showing oblique line, as " people " word, what then form is intermittently more serious, very not attractive in appearance.Often change the display screen of image for need, when need are changed image, the electric wiring of image must be changed, or luminescent device is changed, increased investment and prolonged the duration, make troubles to use.In addition, for the complicated again image of out-of-shape, be difficult to make with prior art.
The utility model purpose provides a kind of el light emitting device that can repeatedly change figure, when it changes at image, need not to change the electroluminescent device on the display screen, also need not to change the electric wiring of the image on this display screen, saved construction investment greatly and accelerated to change visual progress; Simultaneously when showing, this el light emitting device be to show continuously, thus not interrupted splicing partly for oblique line, but continuous whole is vivid attractive in appearance.For the demonstration of complicated shape image, particularly suitable especially.
The utility model is realized by following technical scheme.It comprises several electroluminescent devices, and this device comprises glassy layer, transparent electrode layer, luminescence activity layer and the metal electrode layer of lamination successively; This luminescent device can be arranged arbitrarily and be covered with the formation display screen.Between transparent electrode layer and luminescence activity layer, also has the carrier mobility layer.The material of this luminescent layer can be selected for use and contain the material with photoisomerization character, as trans pyridine styrene.The electroluminescent device that is positioned at position of image is identical with the luminescent device that is positioned at substrate location.Each luminescent device can be arranged the formation display screen anyhow continuously.The device of position of image and the electroluminescent device of substrate location are switched on or switched off it by switch simultaneously by same power supply.Principle of the present utility model is to utilize the physical characteristics of the photoisomerization of this electroluminescent device, make this luminescent device Stimulated Light irradiation, its luminescence activity layer molecular structure becomes cis-structure by transconfiguration at illuminated position, transconfiguration is sent out faint light after energising, and high light is sent out in cis-structure energising back, and the two brightness differs tens times and even tens times.The effect of carrier mobility layer is stability and the efficient that improves device, so can keep clear image.And after device handles by high light or higher temperature, can restore.Shine once more with laser by new image again, then show the image that makes new advances on the display screen of energising back.Therefore the utility model only needs each luminescent device is rearranged display screen, and continuous installation does not interspace between each device.When showing,,, do not have interrupted phenomenon even the oblique line image is also very attractive in appearance owing to arrange continuously between the device.Because use with a kind of device, circuit is simple, it is easy that distribution is installed.
In sum, the utility model adopts with the arrangement that do not interspace continuously of a kind of device, can arrange arbitrarily, employing has the electroluminescent device of photoisomerization physical characteristics, use laser radiation on display screen in image, make its energising back form the different demonstration of brightness, form visual.When image changes, need not to change the luminescent device on the display screen, also need not to change the electric wiring of the image on the display screen, save construction investment greatly and accelerate the progress that image is changed, show attractive in appearancely continuously, do not have interrupted phenomenon, particularly complete attractive in appearance for the demonstration of oblique line image.The utility model both had been suitable for the demonstration of general pattern, and the image demonstration that also is suitable for irregular, complicated image and often needs to change is as billboard, indicator board etc.
Do concrete introduction with embodiment below.
Fig. 1 is a synoptic diagram of the present utility model,
Fig. 2 be A among Fig. 1 to view, the connection diagram of this electroluminescent device 1 is shown,
Fig. 3 is the display screen synoptic diagram of prior art.
As Fig. 1, shown in 2, the utility model comprises the display screen 2 that is made of several same electroluminescent device 1, each luminescent device 1 comprises the glassy layer 11 of stacked arrangement successively, transparent electrode layer 12, luminescence activity layer 13 and metal electrode layer 14, between transparent electrode layer 12 and luminescence activity layer 13, also has carrier mobility layer 15, metal electrode layer 14 connects power cathode, transparent electrode layer 12 connects positive source, transparent electrode layer 12 is made by ITO (indium-Xi-oxide), contain trans pyridine styrene in the material of luminescence activity layer 13, metal electrode layer 14 is made from aluminum.When passing to voltage between positive and negative electrode, glass can be sent out faint light.In the present embodiment, this luminescent device 1 is continuously arranged anyhow, is example with image area 3 for " people " word, by laser display screen 2 was shone 5 minutes, make and contain cinnamic photoactive layer 13 exposures of trans pyridine and partly form cis-structure, and the inner structure of illuminated portion still is not a transconfiguration, and the two luminous difference in brightness is very big, forms image.And " people " word among Fig. 3 shows, luminescent device is arranged very close, but can not show the image of calligraphy art.Positive pole as Fig. 2 power supply E links to each other with the transparent electrode layer 12 of each device 1, and negative pole links to each other with metal level, when K switch is closed, each device is switched on simultaneously, and then image area 3 has tangible luminance difference than substrate part 4 among Fig. 1, forms image, and the oblique line part can show not have interrupted phenomenon continuously.Circuit is simple and reliable.
