Abstract
The utility model relates to an OLED (Organic Light Emitting Diode) image source. The OLED image source adopts a high-brightness OLED display device, and the high-brightness OLED display device is not provided with Polaroids and comprises a glass substrate, a transparent anode located on the glass substrate, at least one group of organic functional material layer and light emitting layer located on the transparent anode and a metal cathode located on the organic functional material layer and the light emitting layer. The utility model has the advantages that a projection system of the OLED image source is the high-brightness OLED display device without an additional lighting system; meanwhile, the OLED display device does not need Polaroids to eliminate ambient light, and thus, the projection system is simplified, the brightness of the OLED is increased, and the cost of projection display products is effectively reduced.
Description
Technical field
The utility model relates to projection display technique, especially relates to the OLED image source of Projection Display product.
Background technology
The Projection Display product is a kind of display unit of image source being amplified imaging behind the several times with projection lens.Image source is the critical component of Projection Display product, and image source can be passive luminous, also can be active illuminating.The image source of existing Projection Display product adopts self luminous CRT or passive luminous micro-display device usually, self luminous CRT volume is very big, progressively withdraw from the market, passive luminous micro-display device needs expensive light source, life-span is short, and micro-display device is made difficulty, and needs illuminator, the optical projection system complexity, the cost height.
The utility model content
Technical problem to be solved by this invention provides a kind of OLED image source, reduces the cost of Projection Display product, enhances product performance simultaneously.
The technical solution adopted in the present invention is: a kind of OLED image source, adopt a high brightness OLED display device, it is characterized in that, described high brightness OLED display device is not with polaroid, comprises glass substrate, is positioned at transparent anode on the glass substrate, is positioned at least one group of organic functional material layer and luminescent layer on the transparent anode, is positioned at the metallic cathode on organic functional material layer and the luminescent layer.
The organic functional material layer of above-mentioned OLED display device has the P type and mixes or N type dopant.
The invention has the beneficial effects as follows: because optical projection system of the present utility model adopts the OLED display device of high brightness, do not need extra illuminator, the OLED display device that the present invention simultaneously adopts, also needn't adopt polaroid to eliminate surround lighting, like this, it is simple not only to have simplified optical projection system, and has improved the brightness of OLED, has effectively reduced the cost of Projection Display product.
Description of drawings
Fig. 1 is the structure and the operation principle schematic diagram thereof of OLED image source described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, OLED image source described in the utility model, adopt a high brightness OLED display device, this high brightness OLED display device is not with polaroid, comprises glass substrate 4, is positioned at transparent anode 3 on the glass substrate 4, is positioned at least one group of organic functional material layer and luminescent layer 2 on the transparent anode 3, is positioned at the metallic cathode 1 on organic functional material layer and the luminescent layer 2.The number of organic functional material layer and luminescent layer 2 can be set at one group, two groups or n (n is a natural number) group as required, and purpose is in order to improve the brightness of OLED display device, to adopt a plurality of luminescent layers to become multiple ground to improve the display brightness of OLED.In order to reduce the driving voltage of OLED display device, can carry out the P type to the organic function layer of this OLED display device and mix or N type doping treatment, add the P type and mix or N type dopant.
The light that this high brightness OLED display device sends sees through projection lens 5 and launches.
Those of ordinary skill in the art will appreciate that embodiment described here is in order to help reader understanding's principle of the present utility model, should to be understood that protection range of the present utility model is not limited to such special statement and embodiment.Everyly make various possible being equal to according to foregoing description and replace or change, all be considered to belong to the protection range of claim of the present utility model.
