− | + | This report presents a brief introduction to OLED (organic light emitting diode) and technologies available for top emission OLED. A detailed taxonomy for OLED is presented covering parts of the type of OLED, material used, manufacturing, applications among others. A detailed landscape analysis of patent and non-patent literature is done with a focus on Top Emission OLED (TEOLED). The product information of major players in the market is also captured for OLED. The final section of the report covers the existing and future market predictions for OLED. | |

+ | =Introduction= | ||
+ | *OLED technology was firstly developed in 1987 at Eastman Kodak Company by Tang and Van Slyke using small-molecule (sm-OLED). In 1990 Richard Friend, Jeremy Burroughes and Donal Bradley discovered electroluminescence capabilities from conjugated polymers so laying down the foundations for a new generation of flat panel displays. | ||
+ | *The growing number of electronic devices using organic light emitting diode displays shows that after years of promise, the technology is increasingly finding place in many products. But while OLED displays might challenge LCDs as the screens of choice for smaller gadgets, the technology may not become mainstream for notebook PCs or TVs within this decade. | ||
+ | *OLED displays use organic compounds that emit light when exposed to an electric current. They are brighter, have better contrast, offer wider viewing angles, use less power, and provide faster response times than liquid crystal displays. OLED screens' thickness is a third of that of LCDs, since they don't need a back-light, and that makes them a good fit for portable electronics devices. | ||

− | + | Traditional light bulbs were invented more than 130 years ago. Since then the basic principle of creating light remains the same, although the design has been tweaked.An electric current passing through a tungsten wire causes it to heat up and glow white hot.Today, more than 20% of electricity used in US buildings is eaten up by lights and nearly half that amount is used by traditional, incandescent light bulbs. It has been a long-term goal of scientists to come up with something that would reduce this mammoth energy demand. | |
− | + | The OLEDs do not heat up like today's light bulbs and so are far more energy efficient and last longer.They also produce a light that is more akin to natural daylight than traditional bulbs. The new polymer uses a fluorescent blue material instead which lasts much longer and uses less energy. | |

+ | | style="background-color:#DCE6F1;padding:0.079cm;"| In the conventional top-emitting organic light emitting device, each pixel electrode is designed to have a minimum width, and neighboring pixel electrodes are designed to be widely spaced apart from each other by as much as 17 .mu.m. Therefore, the wide space between the pixel electrodes leaks emitted light, thereby deteriorating the voltage-current characteristics of the thin film transistors i.e., increasing photo-leakage. | ||
+ | | style="background-color:#DCE6F1;padding:0.079cm;"| In this patent the top-emitting organic light emitting device has maximized the width of a pixel electrode , thereby enhancing aperture ratio. Furthermore, the pixel electrode is arranged to overlap all thin film transistors, so that light is prevented from leaking through a space between neighboring pixel electrodes, thereby reducing photo-leakage of the thin film transistor. | ||

+ | | style="padding:0.079cm;"| Organic electroluminescence panel obtains white light by synthesizing two lights each having complementary color to the other, and the three primary colors differ in luminous intensity. Therefore it is difficult to set chromaticity of white light to desired level. And even after color-filter transmission, red light and blue light will have stronger luminous intensity than green light. | ||
+ | | style="padding:0.079cm;"| The present invention objective provide a light emitting display apparatus having excellent color reproducibility. Organic light emitting layer that synthesizes two or more complementary colors of light that are complementary to each other thereby producing white light. It has a resonant structure by which a resonant wavelength is set to a predetermined wavelength, and outputs the white light via the resonant structure where the predetermined wavelength substantially coincides with a wavelength corresponding to a primary color whose luminous intensity is uniform.With the stated construction, non-uniformity in luminous intensity among three primary colors is alleviated by means of amplified luminous intensity due to resonance. This will help obtain white light in which the primary colors are balanced well. | ||

+ | | style="background-color:#DCE6F1;padding:0.079cm;"| In organic luminescence device, the transparent electrode is formed by a material of a refractive index higher than that of air or nitrogen, constituting the external environment of the organic luminescence device. Therefore, the light emitted from the light emitting layer is reflected at a light emitting surface of the transparent electrode , namely at the interface between the transparent electrode and the air constituting the external environment in FIG. 1. For this reason, such organic luminescence device has been associated with a low efficiency of light emission to the exterior. | ||

+ | | style="background-color:#DCE6F1;padding:0.079cm;"| The disadvantage of oxygen and moisture penetration into the interior of the organic light emitting device is the potential to form metal oxides at the metal-organic interface. These metal oxide impurities may allow separation of the cathode or anode and the organic in a matrix . This can result in the formation of dark non-emitting spots (i.e., no illumination).Edge shorting between the cathode and anode layers is a current problem affecting most conventional organic light emitting display devices. This edge shorting reduces the illuminating potential of the display devices. | ||

+ | | style="background-color:#DCE6F1;padding:0.079cm;"| For manufacture of certain flat panel display devices, such as LCDs or OLED displays, various thin film patterns are formed on panel substrates of the devices, typically using photolithography processes. However, as displays become larger, the amount of material that must be deposited on substrates to form the thin film patterns also becomes larger, inturn increases the manufacturing costs of the panels. | ||
+ | | style="background-color:#DCE6F1;padding:0.079cm;"| Inkjet printing systems have been developed for forming the thin film patterns on the substrates by depositing them on the substrates in the form of special inks. These systems deposit the ink on the substrate through an inkjet head. However, the inkjet head includes a plurality of nozzles, and if only one of these nozzles becomes dysfunctional, the number of passes that the inkjet printing head must make increases. As a result, processing time and costs are substantially increased. | ||

Introduction
- OLED technology was firstly developed in 1987 at Eastman Kodak Company by Tang and Van Slyke using small-molecule (sm-OLED). In 1990 Richard Friend, Jeremy Burroughes and Donal Bradley discovered electroluminescence capabilities from conjugated polymers so laying down the foundations for a new generation of flat panel displays.
- The growing number of electronic devices using organic light emitting diode displays shows that after years of promise, the technology is increasingly finding place in many products. But while OLED displays might challenge LCDs as the screens of choice for smaller gadgets, the technology may not become mainstream for notebook PCs or TVs within this decade.
- OLED displays use organic compounds that emit light when exposed to an electric current. They are brighter, have better contrast, offer wider viewing angles, use less power, and provide faster response times than liquid crystal displays. OLED screens' thickness is a third of that of LCDs, since they don't need a back-light, and that makes them a good fit for portable electronics devices.

Traditional light bulbs were invented more than 130 years ago. Since then the basic principle of creating light remains the same, although the design has been tweaked.An electric current passing through a tungsten wire causes it to heat up and glow white hot.Today, more than 20% of electricity used in US buildings is eaten up by lights and nearly half that amount is used by traditional, incandescent light bulbs. It has been a long-term goal of scientists to come up with something that would reduce this mammoth energy demand.
The OLEDs do not heat up like today's light bulbs and so are far more energy efficient and last longer.They also produce a light that is more akin to natural daylight than traditional bulbs. The new polymer uses a fluorescent blue material instead which lasts much longer and uses less energy.

Samsung Mobile Display Co., Ltd. | Top-emitting organic light emitting device | In the conventional top-emitting organic light emitting device, each pixel electrode is designed to have a minimum width, and neighboring pixel electrodes are designed to be widely spaced apart from each other by as much as 17 .mu.m. Therefore, the wide space between the pixel electrodes leaks emitted light, thereby deteriorating the voltage-current characteristics of the thin film transistors i.e., increasing photo-leakage. | In this patent the top-emitting organic light emitting device has maximized the width of a pixel electrode , thereby enhancing aperture ratio. Furthermore, the pixel electrode is arranged to overlap all thin film transistors, so that light is prevented from leaking through a space between neighboring pixel electrodes, thereby reducing photo-leakage of the thin film transistor. | |||||||

Sanyo Electric Co., Ltd. | Light emitting display apparatus having excellent color reproducibility | Organic electroluminescence panel obtains white light by synthesizing two lights each having complementary color to the other, and the three primary colors differ in luminous intensity. Therefore it is difficult to set chromaticity of white light to desired level. And even after color-filter transmission, red light and blue light will have stronger luminous intensity than green light. | The present invention objective provide a light emitting display apparatus having excellent color reproducibility. Organic light emitting layer that synthesizes two or more complementary colors of light that are complementary to each other thereby producing white light. It has a resonant structure by which a resonant wavelength is set to a predetermined wavelength, and outputs the white light via the resonant structure where the predetermined wavelength substantially coincides with a wavelength corresponding to a primary color whose luminous intensity is uniform.With the stated construction, non-uniformity in luminous intensity among three primary colors is alleviated by means of amplified luminous intensity due to resonance. This will help obtain white light in which the primary colors are balanced well. | |||||||

Canon Kabushiki Kaisha | Organic luminescence device with anti-reflection layer and organic luminescence device package | In organic luminescence device, the transparent electrode is formed by a material of a refractive index higher than that of air or nitrogen, constituting the external environment of the organic luminescence device. Therefore, the light emitted from the light emitting layer is reflected at a light emitting surface of the transparent electrode , namely at the interface between the transparent electrode and the air constituting the external environment in FIG. 1. For this reason, such organic luminescence device has been associated with a low efficiency of light emission to the exterior. | The present invention is to provide an organic luminescence device of a high light-emitting efficiency to the exterior and an organic luminescence device of a satisfactory contrast. A case holding the organic luminescence device in an internal holding space, in which a light emitted from the organic luminescence device, is emitted to the exterior through a light emitting side of the case; wherein anti-reflection means is provided on a light-emitting face on the light-emitting side among faces constituting the internal holding space of the case | |||||||

Eastman Kodak Company | Integrated touch screen and OLED flat-panel display | It has the problem of multiple external electrical connections by employing a flat-panel display having a substrate that extends beyond the substrate of the resistive touch screen. | The present invention has the advantage that it reduces the costs and improves the reliability and performance of a touch screen that is used with an OLED flat-panel display by integrating cable connections on a single substrate and providing touch screen signal processing on the display substrate. | |||||||

FED Corporation | Passive matrix OLED display | The disadvantage of oxygen and moisture penetration into the interior of the organic light emitting device is the potential to form metal oxides at the metal-organic interface. These metal oxide impurities may allow separation of the cathode or anode and the organic in a matrix . This can result in the formation of dark non-emitting spots (i.e., no illumination).Edge shorting between the cathode and anode layers is a current problem affecting most conventional organic light emitting display devices. This edge shorting reduces the illuminating potential of the display devices. | The present invention to provide an insulator layer to minimize edge shorts between lines by separating the OLED layer and the electrode elements. It also provides a sealing structure to isolate the OLED layer from moisture and other contaminants. | |||||||

None | ORGANIC LIGHT EMITTING DIODE DISPLAY AND METHOD OF MANUFACTURING THE SAME | In the organic light emitting layer, as it is easy to transfer energy in an interface between a light emitting layer and a hole transfer layer, a light emitting efficiency and lifetime of the OLED display are reduced because of an energy loss of triplet inside the OLED display. | An interface of the light emitting layer can be improved by forming the inorganic oxide layer between the hole transport layer and the light emitting layer. Further, an energy loss of triplet can be prevented, and the emission efficiency and lifetime can be improved. | |||||||

Samsung Electronics Co., Ltd. | Manufacturing flat panel displays with inkjet printing systems | For manufacture of certain flat panel display devices, such as LCDs or OLED displays, various thin film patterns are formed on panel substrates of the devices, typically using photolithography processes. However, as displays become larger, the amount of material that must be deposited on substrates to form the thin film patterns also becomes larger, inturn increases the manufacturing costs of the panels. | Inkjet printing systems have been developed for forming the thin film patterns on the substrates by depositing them on the substrates in the form of special inks. These systems deposit the ink on the substrate through an inkjet head. However, the inkjet head includes a plurality of nozzles, and if only one of these nozzles becomes dysfunctional, the number of passes that the inkjet printing head must make increases. As a result, processing time and costs are substantially increased. | |||||||

Eastman Kodak Company | Device for depositing patterned layers in OLED displays | To achieve color pixelation in OLED imaging panels, fabrication of a multicolor OLED imaging panel using a shadow masking method is used. A multicolor organic electroluminescent ("EL") medium is vapor deposited and patterned by controlling an angular position of a substrate with respect to a deposition vapor stream. The positioning an element in direct contact with a surface of a substrate can invite problems of abrasion, distortion, or partial lifting, this may cause abrasion, distortion, or partial lifting of the first-color pattern. | The present invention is that a pattern of vaporized material, such as organic material, can be deposited without the use of shadow mask.Another feature is that a plurality of devices can be used for simultaneously depositing different organic materials. Such organic materials can emit light in different ranges of the spectrum. | |||||||

AU Optronics Corp. | Driving method for active matrix OLED display | In one display frame, the current received by the OLED is fixed.The driving method used previously accumulates carriers inside the OLED which reduce the life of the OLEDs. Moreover, the voltage across the OLED gradually increases over timewhich inturn increases power. This effects the OLED over time. | The present invention uses a driving method to neutralize carrier accumulation in the OLED, thereby reducing the increase in voltage and minimizing the increase in power consumption across both ends of the OLED over time, further increasing the life of the OLED. | |||||||

The positioning an element in direct contact with a surface of a substrate can invite problems of abrasion, distortion, or partial lifting, this may cause abrasion, distortion, or partial lifting of the first-color pattern. | The present invention is that the method of color pixelating an organic layer includes providing a plurality of vapor sources disposed outside of a deposition chamber for generating vapors of organic materials, and connecting such vapor sources to a manifold disposed in the chamber. By using vapor deposition method, we can eliminate precision shadow masks. |

Technology Mapping
- In OLED devices not all internally generated light is coupled out of the device (only 20%-50%), which reduces the device efficiency and lifetime.
- Modification in structures are applied to improve outcouple efficiency in order to enhance the efficiency and lifetime of top emission OLEDs.
- Below is a snapshot of how various organizations are using different design structures, using the same principle of internal reflection, to achieve higher out-coupling efficiencies.
Comparison of out coupling of waveguiding light in top-emission polyLED stack
- Some light is reflected out of the OLED at stray angles in typical cases. By using a barrier material (form of microparticles) in the cathode layer, this light at stray angles hits the barrier material, and some of it is reflected back and guided out at the right angles, reducing light loss.
- Microparticles are incorporated in the substrate, which prevents light loss by reflecting light emitted at stray angles.
- A highly reflective anode is provided made of Aluminium or Silver, with a mirror like finish, to reflect light.
- A shielding layer is provided below the anode, across its entire surface, thus increasing the surface area from which light can be reflected outside.
- The reflective layer, anode, is made of a highly reflective surface like Aluminium alloy or silver.
Conclusion
The innovation is towards:
- Incorporating micro-particles structure over the substrate that provide a reflective surface.
- Highly reflective materials using metals like Molybdenum etc.
