Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A method of manufacturing an organic light emitting display device may include:
referring to fig. 1, first, a substrate 11 is prepared. The substrate 11 has a first sub-pixel region, a second sub-pixel region, and a third sub-pixel region. A set of the first sub-pixel region, the second sub-pixel region, and the third sub-pixel region may constitute one pixel region. The substrate 11 may have a plurality of pixel regions. In one embodiment, the first sub-pixel region may be a sub-pixel region emitting red light. The second sub-pixel region may be a sub-pixel region emitting green light. The third sub-pixel region may be a sub-pixel region emitting blue light.
The substrate 11 may be formed of a suitable material such as a glass material, a metal material, or a plastic material including polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide, or the like. A Thin-film transistor (TFT) may be disposed on the substrate 11. In one embodiment, additional layers such as buffer layer 12 may be formed on substrate 11 prior to forming the TFTs. The buffer layer 12 may be formed on the entire surface of the substrate 11, or may be formed by being patterned.
The TFTs may control the emission of each subpixel, or may control the amount of emission when each subpixel emits light. The TFT may include a semiconductor layer 21, a gate electrode 22, a source electrode 23, and a drain electrode 24.
The semiconductor layer 21 may be formed of an amorphous silicon layer, a silicon oxide layer, a metal oxide layer, or a polysilicon layer, or may be formed of an organic semiconductor material. In one embodiment, the semiconductor layer 21 includes a channel region and source and drain regions doped with a dopant.
The semiconductor layer 21 may be covered with a gate insulating layer 25. The gate electrode 22 may be disposed on the gate insulating layer 25. In general, the gate insulating layer 25 may cover the entire surface of the substrate 11. In one embodiment, the gate insulating layer 25 may be formed by patterning. The gate insulating layer 25 may be formed of silicon oxide, silicon nitride, or other insulating organic or inorganic materials in consideration of adhesion to adjacent layers, formability of a stack target layer, and surface flatness. The gate electrode 22 may be covered by an interlayer insulating layer 26 formed of silicon oxide, silicon nitride, and/or other suitable insulating organic or inorganic materials. A portion of the gate insulating layer 25 and the interlayer insulating layer 26 may be removed, and a contact hole may be formed after the removal to expose a predetermined region of the semiconductor layer 21. The source electrode 23 and the drain electrode 24 may contact the semiconductor layer 21 via the contact hole. The source electrode 23 and the drain electrode 24 may be formed of a single material layer or a composite material layer including at least one material of aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), lithium (Li), calcium (Ca), molybdenum (Mo), titanium (Ti), tungsten (W), and copper (Cu) or other suitable alloys in consideration of conductivity.
A protective layer 27 formed of silicon oxide, silicon nitride and/or other suitable insulating organic or inorganic material may cover the TFT. The protective layer 27 covers all or part of the substrate 11. Since the TFT having a complicated layer structure is disposed under the protective layer 27. The top surface of the protective layer 27 may not be sufficiently flat. It is therefore necessary to form a planarization layer 28 on the protective layer 27 in order to form a sufficiently flat top surface.
After the planarization layer 28 is formed, a via hole may be formed in the protection layer 27 and the planarization layer 28 to expose the source electrode 23 and the drain electrode 24 of the TFT.
Then, the first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33 are formed on the planarization layer 28. The first subpixel electrode 31 is formed in the first pixel region. The second subpixel electrode 32 is formed in the second subpixel region. The third subpixel electrode 33 is formed in the third subpixel region. Here, the first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33 may be simultaneously or synchronously formed. Each of the first, second, and third sub-pixel electrodes 31, 32, and 33 may be electrically connected to the TFT through a via hole. The first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33 are generally referred to as anodes.
Each of the first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33 may form a transparent electrode (transflective) or a reflective electrode. When the first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33 form transparent electrodes (transflective type), Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), zinc oxide (ZnO), indium oxide (In)2O3) Indium Gallium Oxide (IGO) or Aluminum Zinc Oxide (AZO).
When the first, second, and third sub-pixel electrodes 31, 32, and 33 form a reflective electrode, a reflective layer, which may be formed of silver (Ag), magnesium (Mg), aluminum (Al), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), or a mixture of any of these materials, and an auxiliary layer, which may be formed of a transparent electrode material such as Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), zinc oxide (ZnO), and indium oxide (In2O3), are stacked to form a reflective electrode layer. Here, the structure and material of the first, second, and third subpixel electrodes 31, 32, and 33 are not limited thereto and may vary.
After the first, second, and third sub-pixel electrodes 31, 32, and 33 are formed, as shown in fig. 1, a pixel defining layer 41(PDL) may be formed. The PDL is formed to cover the first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33 at the same time. The PDL may be used to define the sub-pixels by having an opening corresponding to each sub-pixel (i.e., a central portion opening exposing each sub-pixel). The PDL may be formed of a single material layer or a composite material layer including a suitable inorganic material or a suitable organic material among materials such as polyacrylate and polyimide.
The PDL may be formed in such a manner that a layer for the PDL is formed by using a material suitable for the PDL on the entire surface of the substrate 11 to cover the first subpixel electrode 31, the second subpixel electrode 32, and the third subpixel electrode 33. Then, the PDL layer is patterned to expose central portions of the first, second, and third subpixel electrodes 31, 32, and 33.
The light emitting layer 51 may be formed by evaporating a light emitting material. The evaporation material covers a portion of the first subpixel electrode 31 not covered by the PDL layer, a portion of the second subpixel electrode 32 not covered by the PDL layer, a portion of the third subpixel electrode 33 not covered by the PDL layer, and the top surface of the PDL layer.
A precision metal mask plate may be used to evaporate the light emitting materials that emit red, green, and blue light.
Then, the counter electrode 61 covering the first sub-pixel region, the second sub-pixel region, and the third sub-pixel region is formed by vapor deposition. The counter electrode 61 may be integrally formed with respect to the plurality of sub-pixels so as to cover the entire display area. The counter electrode 61 is commonly referred to as a cathode.
The counter electrode 61 contacts the electrode supply line outside the display area so that the electrode supply line can receive an electric signal. The counter electrode 61 may be formed as a transparent electrode or a reflective electrode. When the counter electrode 61 is formed as a transparent electrode, the counter electrode 61 may include a layer formed by depositing Li, Ca, LiF/Al, Mg, or a mixed material of any of these materials In a direction toward the light emitting layer and a layer formed of a material including ITO, IZO, ZnO, or In2O3An auxiliary electrode or a bus electrode line formed of a transparent (transflective) material. When the counter electrode 61 is formed as a reflective electrode, the counter electrode 61 may have a layer including one or more materials selected from Li, Ca, LiF/Al, Ag, and Mg. However, the configuration and material of the counter electrode 61 are not limited thereto, and thus may be changed.
Referring to fig. 2, a display screen provided by the present application includes: the display device comprises a first display area, a second display area adjacent to the first display area, and a third display area adjacent to the second display area and located on the opposite side of one side, adjacent to the first display area, of the second display area;

the sub-pixel density of the second display area is smaller than that of the third display area.
An Active Matrix Organic Light Emitting Diode (AMOLED) is a display technology in which Organic Light Emitting Diode (OLED) pixels are deposited or integrated on a TFT array, and the current flowing into each OLED pixel is controlled by the TFT array, so as to determine the intensity of Light emitted by each pixel.
The display screen in the embodiment provided by the application can be prepared by adopting the AMOLED technology. The preparation method refers to the method of the organic light-emitting display device. Wherein the sub-pixel density of the first display area 100 is less than the sub-pixel density of the second display area 200. A particular implementation may be to define openings with PDL layers for the deposition of sub-pixels. Then, sub-pixels are evaporated in the openings defined by the PDL layer by using an evaporation process, so that the sub-pixel density of the first display area 100 is lower than that of the second display area 200. It will be appreciated that control of the sub-pixel density may be achieved by the number of openings or aperture ratio defined by the PDL layer. Of course, the same method may be used so that the sub-pixel density of the second display region 200 is less than that of the third display region 300.
In one particular application of a display, such as a cell phone display. A conventional display screen of a mobile phone may include a first display area 100 where a camera is provided and a third display area 300 mainly for displaying an image. In the embodiment shown in fig. 2, the third display area 300 is distributed in the middle of the display screen as the main display area of the display screen. The first display area 100 is distributed on the upper side of the display screen as an auxiliary display area of the display screen. It should be noted that the positional relationship between the first display area 100 and the third display area 300 here may be adjusted according to actual situations. For example, the first display area 100 may be located at the left, right, or lower side of the third display area 300. Alternatively, the first display area 100 is distributed around the third display area 300, and surrounds the third display area 300 in the middle. As long as there are two opposite regions of the display screen that require different illumination intensities, it should be understood that the scope of the present application is not to be substantially excluded. Meanwhile, a transitional second display area 200 is provided between the first display area 100 and the third display area 300.
Referring to fig. 3, another embodiment of the present disclosure is also shown, in the embodiment shown in fig. 3, a third display area 300 is distributed in the middle of the display screen as a main display area of the display screen. The first display area 100 is distributed on the upper side of the display screen as an auxiliary display area of the display screen. It should be noted that the positional relationship between the first display area 100 and the third display area 300 here may be adjusted according to actual situations. For example, the first display area 100 may be located at the left, right, or lower side of the third display area 300. Alternatively, the first display area 100 is distributed around the third display area 300, and surrounds the third display area 300 in the middle. As long as there are two opposite regions of the display screen that require different illumination intensities, it should be understood that the scope of the present application is not to be substantially excluded. Meanwhile, a transitional second display area 200 is provided between the first display area 100 and the third display area 300.
The sub-pixel density of the camera is set through adjusting the display screen, the requirement of normal display of the camera is met, the requirement that the camera needs to keep higher light transmittance is also met, the position does not need to be reserved for the front camera, so that a non-display area above the effective display area can be saved, the screen occupation ratio is enlarged, the use experience is optimized, and therefore the technical problem that the use experience of a user is poor due to the existence of the non-display area can be solved.
Further, in an embodiment provided by the present application, in the first display region, a first type light emitting unit is formed by sharing sub-pixels in a first manner;
