Abstract
This invention discloses an organic luminescent diode display with lens reflection conversion function, which comprises one metal electrode layer, one organic luminescent diode layer, one phase conversion board and one deflection board, wherein, the phase conversion board has one quarter of wavelength phase difference of relay status with zero phase difference. Through the matching between the phase conversion board and the deflection board, it can eliminate the reflection interference when the diode layer reflects and can provide lens image when the diode doesn' t reflect.
Description
Technical field
The present invention relates to a kind of organic light emitting diode display, relate in particular to a kind of organic light emitting diode display with the minute surface translation function.
Background technology
General organic light emitting diode display, in order to eliminate the reflective of metal electrode layer, one quarter-wave wave plate (1/4 λ film) can be installed above the Organic Light Emitting Diode layer in regular turn, reach a Polarizer, it utilizes the optical characteristics of quarter-wave wave plate and Polarizer, can eliminate the reflective of metal electrode layer.
General mirror display is based on LCD (Liquid Crystals Display), attaches liquid crystal panel (Twist Nematic Cell) thereon, and brightening piece (DBEF is used in collocation; Dual Brightness Enhancement Film), have the display of mirror effect with formation, but, cost is increased, and its final penetrance still can't solve the problem of briliancy deficiency still below 9% because its light utilization is not good.
Summary of the invention
Fundamental purpose of the present invention is to address the aforementioned drawbacks, and for avoiding the existence of this defective, the invention provides a kind of antireflection light and has the high brightness indicator of mirror effect.
The present invention utilizes the Organic Light Emitting Diode layer to have the characteristic of high brightness, be furnished with a phase transition plate, a Polarizer thereon in regular turn, the arranged beneath of Organic Light Emitting Diode has metal electrode layer, in order to service voltage, and its phase transition plate has the delaying state of quarter-wave phase differential, and be convertible into the delaying state of zero phase difference, in view of the above when the Organic Light Emitting Diode layer is luminous, the phase transition plate is in the delaying state of quarter-wave phase differential, in order to eliminate the reflective of metal electrode layer; When the Organic Light Emitting Diode layer was not luminous, the phase transition plate was in the delaying state of zero phase difference, utilized the reflecting effect of metal electrode layer, made display have the effect of minute surface.

Embodiment
For to feature of the present invention, purpose, and effect can more in depth understand and approval, now enumerate preferred embodiment and conjunction with figs. is described as follows:
See also Fig. 1, Organic Light Emitting Diode layer 10 arranged beneath have metal electrode layer 20 in order to service voltage, luminous to drive Organic Light Emitting Diode layer 10, therefore when external environment is injected incident light 30, it can be because the reflecting surface 201 of metal electrode layer 20, cause Ambient 31, form serious reflective interference, and then have influence on the demonstration light 36 of display itself.
See also Fig. 2, it is an organigram of the present invention, the present invention includes a metal electrode layer 20, is used for service voltage, and has a reflecting surface 201; One Organic Light Emitting Diode layer 10 is positioned at the top of this metal electrode layer 20, behind these metal electrode layer 20 service voltages, but self-lighting; One phase transition plate 40 is positioned at the top of this Organic Light Emitting Diode layer 10, and this phase transition plate 40 has the delaying state of quarter-wave phase differential, and is convertible into the delaying state of zero phase difference, and a Polarizer 50 is positioned on this phase transition plate 40.
When Organic Light Emitting Diode layer 10 is luminous, phase transition plate 40 is in the delaying state of quarter-wave phase differential, see also Fig. 3, environment incident light 30 is during by extraneous incident, it is earlier through Polarizer 50, form the line polarisation, the state of this moment is referred to as A, and this environment incident light 30 is through phase transition plate 40 time, it is by the line polarisation of state A, convert left-handed polarization to, it passes Organic Light Emitting Diode layer 10, via the reflection of metal electrode layer 20, form the dextrorotation polarisation, be Ambient 31 this moment, and the dextrorotation polarisation is at process phase transition plate 40, and it can be transformed into the line polarisation of state B, the line polarisation of this state B and the line polarisation of state A are compared, its polarization angle differs 90 °, so the line polarisation of state B can block by Polarizer 50, in view of the above to eliminate Ambient 31.
When Organic Light Emitting Diode layer 10 is not luminous, phase transition plate 40 is in the delaying state of zero phase difference, see also Fig. 4, environment incident light 30 is during by extraneous incident, it is earlier through Polarizer 50, form the line polarisation, through phase transition plate 40 time, do not change its polarization state, it passes Organic Light Emitting Diode layer 10, reflecting surface 201 reflections via metal electrode layer 20, form the line polarisation of identical polarization direction, be referred to as Ambient 31, the line polarisation can pass through Polarizer 50, utilize the reflecting effect of Ambient 31 in view of the above, can form display with mirror effect.
Please consult Fig. 5 again, it is for the making flow process of organic light emitting diode display of the present invention, as shown in the figure, step 5A is an electrode of making specific pattern on an electro-conductive glass, then step 5B makes the patterning shelves wall that ink jet printing is used thereon, behind step 5C printing light-emitting component (Organic Light Emitting Diode layer 10), and toasted to solidify, pass through step 5D evaporation metal electrode layer 20 again, and encapsulated, final step 5E makes guiding device at the transparent surface of display, via step 5F element test, promptly finishes making again.
Please consult Fig. 6 again, for the present invention adopts the making process flow diagram of liquid crystal panel as phase transition plate 40, step 6A is an electrode of making specific pattern respectively at an electro-conductive glass, and step 6B is for being coated with the orientation agent thereon respectively, and brushing orientation (rubbing), step 6C is for to combine it in twos, and toasted being solidified togather, step 6D injects liquid crystal again, and in addition directed, step 6E is with its encapsulation and carry out electrical measurement, promptly finishes the making of phase transition plate 40.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
