Abstract
The invention relates to an OLED device of a high-mounted stop lamp. An original light source light-guide panel of a stop lamp has the defects that the requirement for machining precision is very high, cost is also high, light uniformity is poor and glare can be easily caused to lead to traffic accidents. The OLED device is characterized in that the OLED device comprises a circuit board (1), an OLED film (2) is installed on the circuit board, a face cover (3) is installed above the OLED film, and two radiation films (4) are arranged at the two ends of the face cover. The OLED device is used in the high-mounted stop lamp.
Description
technical field:
the present invention relates to a kind of OLED device of high-mount stop lamp.
background technology:
along with the development of automobile industry, and the requirement of people to car light Visual Aesthetics, increasing automaker starts to pay close attention to the application of area source on vehicle light shape.Yet, brake lamp light source is generally bulb or light emitting diode (LED), want to realize uniform banded effect, the most frequently used method is to adjust the distance of the lens of LED and secondary optics, along with the increase of its distance, banded effect is more obvious, but meanwhile, wasted a lot of energy, the utilization rate of the LED light source that light efficiency is not high is originally reduced more, due to lambert's LED body characteristics of luminescence, cause light-emitting area limited.Also have a kind of method to utilize exactly backlight assembly, but this method is very high to the requirement on machining accuracy of light guide panel, cost is also high, and the uniformity of light is not fine, easily causes dazzle, causes the generation of traffic accident.
although compare LED with bulb, improved energy-saving effect, heat-resisting very poor due to LED, will inevitably bring the problem in chip life-span.The design of existing LED lamp is often dispelled the heat and is difficult to reach requirement, a heat radiation, require very harsh field, so that some light fixtures will add plastic bushing to increase the reliability of insulation between drive plate and aluminium radiator fin, also need to fill with thermal grease to improve heat-sinking capability.Secondly, the LED wick life-span is index reduction with the rising of temperature; The every rising ten of electrochemical capacitor temperature is spent the life-span and is reduced half; MOS temperature raises, and internal resistance increases, and loss increases, and temperature can raise again (constant current mode), finally burns.The light decay of LED is very serious in addition, so the life-span of light fixture should also will be considered visual experience, through how long, the brightness of light fixture is reduced to the degree of visually feeling dark exactly.
oLED is brighter than LED.OLED organic layer is than in LED, corresponding mineral crystal layer is thin a lot of with it, thereby the conductive layer of OLED and emission layer can adopt sandwich construction.
oLED illumination and Display Technique are different from traditional lighting mode, without backlight, adopt very thin coating of organic material and glass substrate; when having electric current to pass through; these organic materials will be luminous, is secondly that this kind of high-mount brake lamp can significantly be saved electric energy, protection of the environment.It is the novel energy-saving light fixture that replaces traditional automobile lamp light source.
summary of the invention:
the object of the present invention is to provide a kind of OLED device of high-mount stop lamp.
the object of the present invention is achieved like this:
an OLED device for high-mount stop lamp, its composition comprises: circuit board, OLED film is arranged on described circuit board, and described OLED film top is provided with face shield, is provided with two radiation films at described face shield two ends.
the OLED device of described high-mount stop lamp, the thickness of described OLED film is less than 1 millimeter.
the OLED device of described high-mount stop lamp, described face shield is made by the plastics with light diffusion effect, and described face shield has optical patterns.
the OLED device of described high-mount stop lamp, described OLED film is solid-state anti-shock mechanism, wide visual angle picture is undistorted; Response time is short, low-temperature characteristics good, converges the reflectance coating of the light sending OLED side, makes being utilized of Energy Efficient, improves the utilization rate of luminous energy; The simple drive circuit of OLED reaches luminous, supports simple; Adopt active type of drive, without dutycycle problem, the redness of brightness and blue pixel are independently carried out to gray scale and regulate and drive, favourablely realize with OLED colorize, what make that high-mount stop lamp independently shows becomes a reality; OLED relies on current drives, and its brightness is directly proportional to the magnitude of current, drives the restriction that is not subject to scan electrode number, realizes high brightness.The drive circuit of active matrix is hidden in display screen, realizes integrated and miniaturization, solves the connectivity problem of peripheral drive circuit and screen, has improved whole lamp reliability.
beneficial effect:
1. the present invention combines brake lamp with car-mounted display, can release motor state now or car owner's mood or advertisement, improved car and extraneous communicative channel, realize the intellectuality of car with personalized, be easy to be designed to various modeling structures, safety is attractive in appearance, long service life.
2.OLED self self-luminous does not need backlight, contrast is high, visual angle is wide, reaction speed is fast, can realize function Ads on Vehicles and information issue, OLED itself is a kind of of area source, and its circuit is simple, so can be made into the structure of certain decorative pattern.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
the specific embodiment:
embodiment 1:
an OLED device for high-mount stop lamp, its composition comprises: circuit board 1, OLED film 2 is arranged on described circuit board, and described OLED film top is provided with face shield 3, is provided with two radiation films 4 at described face shield two ends.
embodiment 2:
according to the OLED device of the high-mount stop lamp described in embodiment 1, the thickness of described OLED film is less than 1 millimeter.
embodiment 3:
according to the OLED device of the high-mount stop lamp described in embodiment 1, described face shield is made by the plastics with light diffusion effect, and described face shield has optical patterns.
embodiment 4:
according to the OLED device of the high-mount stop lamp described in embodiment 1, described OLED film is solid-state mechanism, there is no liquid substance, therefore anti-seismic performance is better, is not afraid of and falls, and almost there is no the problem of visible angle, even watch under very large visual angle, picture is still undistorted; Response time is short, shows that motion picture absolutely not has the phenomenon of smear; Low-temperature characteristics is good, when 40 degrees below zero, still can normally show; The effect of reflectance coating is existing in order to converge the light sending OLED side, and being utilized of Energy Efficient, realizes the good utilization of luminous energy; OLED only needs simple drive circuit can reach luminous, supports simple.This patent adopts active type of drive, and active driving is without dutycycle problem, can independently carry out gray scale to the redness of brightness and blue pixel and regulate and drive, and favourablely realizes with OLED colorize, and what make that high-mount stop lamp independently shows becomes a reality; OLED relies on current drives, and its brightness is directly proportional to the magnitude of current, and active driving, without dutycycle problem, drives the restriction that is not subject to scan electrode number, easily realizes high brightness.The drive circuit of active matrix is hidden in display screen, is easier to realize integrated and miniaturization, and owing to solving the connectivity problem of peripheral drive circuit and screen, this has improved whole lamp reliability to a certain extent.
