Scope of the invention The present invention relates to organic light-emitting devices (n0LEDs); and more specifically, to multi-color organic light-emitting devices having a polymer hole transport layer and containing small molecule materials to provide low leakage and high efficiency. Exciton blocking and electron transport layer. The OLED of the present invention is suitable for single-color, multi-color and full-color, passive or active matrix displays. BACKGROUND OF THE INVENTION Organic light-emitting devices (OLEDs) are promising technologies for next-generation flat-panel displays. OLED-generally consists of a small molecule or polymer layer placed between the anode and cathode. The polymer can be self-emissive or doped with dye molecules. When a current is applied, the electrons and holes from the respective electrodes Injected, and then combined to form radiation decay and excitons that emit light. The color of light emission is determined by the energy level of the emitting species. The active full-color OLED display requires individual RGB pixels to emit the correct color, with low Leakage current and high yield. Because the conventional lithography method used in the semiconductor industry destroys organic substances, it produces full-color OL One of the main challenges of ED displays is to deposit RGB OLED pixels on the same substrate. The small paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) 550971 A7 B7 V. Description of the invention (2 ) _ " ~ Thermal vacuum deposition of molecular materials through orifices is a standard practice adopted in the industry, but it has poor material utilization, low output, and cannot be easily scaled up to large substrates. There are two types of pattern formation methods that are particularly suitable for high-speed, large-area manufacturing of polymer OLEDs: inkjet deposition of emissive polymers or dopants and thermal dye transfer (T · R.

However, these pattern-deposited polymers Oled have problems of low efficiency and high leakage current due to the surface morphology of the resulting thin film, and require additional processing. One reason for the low efficiency in these OLEDs is the high hole mobility in the polymer layer compared to the electron mobility. As a result, many holes penetrate the entire device without recombining with electrons to form excitons. Alternatively, the exciton can be formed near the metal cathode and quenched by the cathode before it can emit light. Figure 1 shows a conventional OLED with a single polymer layer. A glass substrate 10 forming the bottom layer of the device is first provided. A transparent indium tin oxide (ΓITO) anode 15 is then deposited on the glass substrate 10. An organic polymer layer 20 is deposited on the ITO anode 15 and a cathode 140 is deposited on the polymer 20. As shown in Figure 2a As shown, a dye dopant can be selectively deposited on the polymer 20 to produce sub-pixel elements, such as red, green, and blue light-emitting elements.

However, as far as I know, in all of these devices, The light emission system is from Alq, which is green, so individual RGB pixels cannot be obtained. It would be advantageous to provide a multi-color OLED array with exciton blocking and electron transport layers to provide low leakage and high efficiency, but currently No such multicolor OLED array Therefore, an object of the present invention is to improve a polymer layer having a pattern deposited polymer layer by depositing a small molecule barrier layer such as disclosed in U.S. Published Patent Application Nos. 2001 / 0,043,044 and 2001 / 0,052,751 on a polymer layer.

One or more additional layers of small molecular materials can be deposited on the polymeric layer to Manufacturing of OLEDs with improved external quantum efficiency. This method can use virtually any method known in the art to pattern emissive polymerized regions in a multi-color array of pixels.

Description of the invention (10) A transparent conductive oxide, such as indium tin oxide (ITO), zinc indium tin oxide, or the like is preferred. The cathode is a low work function electron injection material, such as a metal layer. Cathodes such as LiF / Al or Mg: Ag can also be used. The latter can be used in combination with ITO as a compound cathode. In another specific embodiment of the present invention, the polymer hole injection layer (HIL) may exist between the anode layer and the polymer hole transport layer, or between the anode layer and the emission layer. The hole injection material of the present invention may be characterized by planarizing or wetting the surface of the anode to provide an efficient hole injection from the anode into the hole injection material. The hole injection material of the present invention is generally characterized by having a HOMO energy level that favorably cooperates with an adjacent anode layer on one side of the HIL layer and an HTL or an emission layer on the opposite side of the HIL. Therefore, a preferred property of the HIL material is that holes can be efficiently injected from the anode into the HIL material. Although HIL materials are still hole-transporting materials, they are generally different from the conventional hole-transporting materials typically used in the hole-transporting layers of OLEDs. Among them, this HIL material has substantially more holes than conventional ones. The hole mobility of the material being transported is low. Preferred HIL materials include polymeric materials such as poly-3,4-ethylenedioxy-4-phene (πPEDOT ") or poly (ethylene-dioxane): poly (styrenesulfonic acid) (PEDOT: PSS), It can effectively promote the injection of holes from the anode into the HIL material, and then into the HTL or EL. Polyaniline (PANI) can also be used as the HIL material. The polymer layer used can be deposited by methods known in the art One of the preferred methods for polymer deposition is by spin-coating the polymer with a suitable solvent. Small molecule materials can be vacuum deposited using techniques known in the art.

Introduction of the invention (15) into the organic layer 120 'The barrier layer 130 is deposited on the organic polymer layer 120. The barrier layer 130 restricts the exciton to the organic polymer layer ι20, but still allows electrons to pass through. This form can ensure the emission of the organic polymer layer 120. Dopants 122a-122c control the development of OLED If there is no barrier layer 13, the excitons generated in the organic polymer layer 120 can be removed from the layer 120, which causes the OLED to have the problem of distorted color emission. One of the present invention is preferred and specific In the embodiment, the barrier layer 130 is a 2,9-dimethyl · 4,7-diphenyl _: [10_ phenoline (BCP) 6 nm thick layer, but other materials and dimensions are also considered to be Within the scope of the present invention, the barrier layer 13 has a sufficiently low electronic barrier to allow electrons to pass through and enter the organic polymer layer 120. In addition, the barrier layer 130 has a sufficiently low HOMO characteristic and can block The hole enters the layer above it (ie, the electron transport layer 135, which is described in more detail below). Figure 3c shows further manufacturing steps of the invention. The electron transporting layer 135 is deposited on the barrier layer 130 to reduce the reverse leakage current of the LED, and to remove the cathode of the OLED from the organic polymer layer 120 which is also a hole transporting and emitting layer. By removing the cathode from the organic polymer layer 120, the electron transport layer 135 reduces the cathodic quenching effect of the exciton via the dipole-metal interaction, and balances the transport of electrons and holes, thereby improving the efficiency of the LED. . In a preferred embodiment of the present invention, the electron transporting layer 135 is a 40 nm thick layer of aluminum quinolinol (Alq). However, other materials and sizes can be used in accordance with the present invention. The electron transport layer 135 may be deposited on the barrier layer 130 using continuous thermal evaporation, or other deposition techniques known in the art. Finally, as shown in FIG. 3d, a cathode 14 is deposited on the transport layer 135. The cathode 140 is 150 nanometers thick and consists of 50 nanometers of Mg: Ag (l0: 1) / 100 nanometers of Ag-18.

Description of the invention (16) is better 'but other materials and other dimensions known in the art are also considered to be within the scope of the present invention. The fully produced OLED generates light in the organic polymer hole transport and emission layer 120 and transmits the light through the layers 110 and 115 in the general direction indicated by arrow a. The important point is that the barrier layer 130 and the transport layer 135 can ensure that the light emission system is limited to the organic layer 120, and especially the doped regions 122a-122c, to provide a variety of colors. Figures 4a-4b are band diagrams comparing an OLED of the present invention with a conventional OLED without an electron transport or barrier layer. The figure shows the leakage current due to holes and electron tunneling of the two devices. Fig. 4a is a reverse bias energy band diagram of the LED of the present invention. Figure 4b is a reverse bias band diagram of a conventional 101ED without an electron transport or blocking layer. As can be seen from the figure, the presence of the barrier layer 13 and the transport layer 135 of the present invention increases the hole with the penetration from 1.84 electron volts (eV) to 2.1 electron volts, thereby greatly suppressing the reverse leakage current of the device and providing increased effectiveness.

As mentioned earlier, the glass substrate 110 forms the bottom layer of the OLED, and an ITO anode 115, an organic polymer layer 120, a barrier layer 130, an electron transport layer 135, and a cathode 140 are deposited thereon. During the operation of the OLED, the electrons 150 of the cathode 14 move through the layers 135 and 130 of the device, and enter the organic polymer layer 120. At the same time, the holes 152 of the 'anode Π5' move into the organic polymer layer 120. When the electrons 150 and the holes 152 meet in the organic layer 120, excitons 154 are formed, and they are recombined in the polymer layer 120 to emit visible radiation 156. The emitting dopant in the organic polymer layer 120 controls the color of the visible radiation 156, and produces light of different colors (i.e., red, green, and blue to form a multi-color display). -19 · This paper standard is applicable to 0 S family standard (CNS) A4 specification (21G X 297 public love) '-550971 A7 B7 V. Description of the invention (17 The resist layer 130 importantly prevents excitons 154 from moving into the device In the layer outside the organic polymer layer 120. In addition, the low homo (the highest occupied molecular orbital) of the barrier layer n0 prevents holes from reaching the layer 13 or 35. This can be ensured at the layer 3 or 1 3 5 The exciton is not formed in the layer, so that the emitting dopant in layer i 20 controls the emission color. In addition, 'the exciton's cathode quenching is eliminated because no exciton is formed in layer 135 or no exciton reaches layer 135'. Therefore, the efficiency of OLED is improved. In addition, the electron transporting layer 135 suppresses tunneling of the hole and reduces the reverse leakage current. Visible radiation 156-once formed, it can be seen through the anode 5 and the substrate 110 'Thus, 〇LED can efficiently generate and emit polychromatic light. Figure 6 is a graph showing exciton formation, emission properties, and sample energy levels of the oled of the present invention. As can be seen in the figure, when the electrons are 150 And holes 152 travel toward the organic polymer layer 120, they each experience different energy levels For example, when initially introduced from the electron source 160 (ie, the cathode of the OLED), the electron 150 initially has an energy level that is 3.7 electron volts lower than the vacuum value of the Mg: Ag cathode. When the electron 150 moves through the electron transport When the layer 135 and the barrier layer 13 o, the energy levels drop to 3.1 electron volts and 2.9 electron volts below the vacuum value, respectively. When the electrons finally enter the organic polymer layer 120, they have about 2.5 electron volts below the vacuum value. When the hole 152 is introduced through the hole source 162 (ie, the anode of the OLED), the hole 152-begins to occupy an energy level of 5.0 electron volts below the vacuum value (electron energy).

Description of the invention (18) Combined with the emission of visible radiation 156. The doped region 122 significantly controls the color of the visible radiation 156. The barrier layer 130 and the electron transport layer 135 ensure that the exciton 154 stays in the organic polymer layer 120, and prevent cathode quenching and hole tunneling. 7a-7d are diagrams showing the optical and electrical properties of the multilayer OLED of the present invention. Figure 7a shows the OLED current density, detection photocurrent density, and voltage characteristics of OLEDs with and without the electron transport layer of the present invention. As can be seen from the figure, an OLED with an electron transport layer has a much lower leakage current in a reverse bias mode than an OLED without an electron transport layer. In addition, the addition of an electron transport layer does not increase the operating voltage of the OLED. Therefore, there is an electron transport layer to suppress the leakage current without increasing the operating current of the OLED. Fig. 7b shows the electroluminescence spectrum of an OLED (having three different emissive dopants; blue, green, and red) according to the present invention. Measure the normalized intensity in arbitrary units (a.u ·) and plot it against the blue, green, and red wavelengths emitted by the OLED. The device emits blue, green, and red with sharp wavelengths of 436 nm, 500 nm, and 590 nm, respectively. Such a device can be formed by adding emissive dopants white mann (blue), coumarin 6 (green), and Nile red to the polymer layer 120 of the present invention. Figure 7c shows the current density (V) and voltage (V) characteristics of OLEDs fabricated using barrier layers (BCP) with different thicknesses. As can be seen from the figure, BCP layers of different thicknesses do not cause a significant increase in the operating voltage of the OLED. Therefore, the presence of the BCP layer increases the optical efficiency of the OLED without adversely affecting the operating voltage.
