It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
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.
Buffer layer 12 may be of any suitable material including PET, PEN, polyacrylate and/or polyimide, in a layered structure in a single layer or a multi-layer stack. The buffer layer 12 may also be formed of silicon oxide or silicon nitride, or may include a composite layer of an organic material and/or an inorganic material.
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 the 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 is formed of a transparent electrode material such as Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), zinc oxide (ZnO), indium oxide (In2O3), are stacked to form the reflective electrode layer, where the structures and materials of the first, second, and third sub-pixel electrodes 31, 32, and 33 are not limited thereto and may be varied.
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 includes: a first area 100 and a second area 200;
wherein the sub-pixel density of the first region 100 is lower than the sub-pixel density of the second region 200.
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 region 100 is lower than the sub-pixel density of the second region 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 region 100 is lower than that of the second region 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.
In one particular application of a display, such as a cell phone display. A conventional display screen of a cellular phone may include a first area 100 where a camera is provided and a second area 200 mainly for displaying an image.

The first 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 area 100 and the second area 200 here may be adjusted according to actual situations. For example, the first area 100 may be located on the left, right, or lower side of the second area 200. Alternatively, the first regions 100 are distributed on the periphery of the second region 200, and surround the second region 200 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.
In the present application, the first area 100 and the second area 200 are formed on the display screen of the mobile phone by controlling the sub-pixel density, and both the first area 100 and the second area 200 can be used for displaying images, that is, the whole display screen can be displayed when the whole display screen is observed by naked eyes, that is, the whole display screen is a so-called full screen. Because need not be for leading camera reservation position, consequently can save the non-display area of effective display area top, enlarge the screen and account for the ratio, optimize and use the impression to, can solve the existence of non-display area and lead to user's the not good technical problem of use impression. Moreover, the density of the pixel units in the first area 100 is relatively low, so that the requirement of the illumination intensity of the photosensitive module under the screen of the mobile phone can be met.
Referring to fig. 2 and 3, in another embodiment provided in the present application, first type light emitting units are distributed in the first area;
the first type of light emitting unit comprises 1 first sub-pixel, 2 second sub-pixels and 1 third sub-pixel;
the sub-pixels of the first type of light-emitting unit are distributed in a shape of a pair of triangles sharing a common side;
the first sub-pixel and the third sub-pixel are located on a common edge, and the second sub-pixel is located on the other two vertexes.
In the embodiment provided by the application, on the basis of the main display area of the conventional display screen, no change is made, that is, the second area 200 is not changed, and the sub-pixels of the auxiliary display area of the conventional display screen are changed, that is, the sub-pixels of the first area 100 are changed, so that the first type of light-emitting units in the first area are different from the light-emitting units in the second area, and thus, light can penetrate from the sub-pixel gaps of the first area to realize higher light transmittance, so that full-screen or full-screen display is realized, and meanwhile, the work of the photosensitive module under the screen is not influenced. Specifically, the number of at least one of the red, green, and blue sub-pixels is made different from the number of the other two sub-pixels. Or it will be understood that white balance will be achieved by sharing at least one of the red, green and blue sub-pixels while providing a gap through which light passes.
Referring to fig. 4 and 5, in another embodiment provided in the present application, the second type of light emitting units are distributed in the first area;
the second type of light-emitting unit comprises 1 first sub-pixel, 2 second sub-pixels and 2 third sub-pixels;
the sub-pixels of the second type of light-emitting unit are distributed in a pair of triangular shapes sharing a vertex;
the first sub-pixel is located at a common vertex, and the second sub-pixel and the third sub-pixel are located at the other two vertices.
Referring to fig. 4 and 5, the second type of light emitting units are disposed in the first region 100. The second type of light-emitting units are distributed in the shape of a pair of triangles sharing a vertex. The specific structure or minimal repeating unit of the second type of light-emitting unit is shown in fig. 5 in detail, and comprises 1 red sub-pixel, 2 green sub-pixels and 2 blue sub-pixels, wherein the red sub-pixels are located at a common vertex, and the green sub-pixels and the blue sub-pixels are located at two other vertices.
It is to be understood that the red, green and blue sub-pixels are only exemplified by the most common red, green and blue sub-pixels, and that the red, green and blue sub-pixels can be replaced by sub-pixels of other colors.
Referring to fig. 2 and 4, the common red sub-pixel, the blue sub-pixel and the common red sub-pixel are used to realize white balance and provide a gap for light to pass through, so as to meet the requirement of the illumination intensity or the light sensing amount of the photosensitive module under the screen. It is understood that the white balance is realized in a sub-pixel sharing manner while providing a gap for light to pass through, and the technical solution that meets the requirements of the illumination intensity or the light sensing quantity of the photosensitive module under the screen should be understood as not departing from the scope of the substantial protection of the present application.
Referring to fig. 2 and 4, in another embodiment provided in the present application, a third type of light emitting unit is distributed in the second area;
the third type of light emitting unit comprises 1 first sub-pixel, 1 second sub-pixel and 1 third sub-pixel;
the sub-pixels of the third type of light-emitting unit are distributed in a triangular shape.
As can be seen from fig. 2 or fig. 4, the light emitting units of the third type in the second region may be considered as three sub-pixels which are alternately distributed in a triangular shape.
In yet another embodiment provided herein, the first sub-pixel, the second sub-pixel, and the third sub-pixel are red, green, and blue, respectively.
The first sub-pixel, the second sub-pixel and the third sub-pixel may emit color lights of different colors, for example, three colors of red (R), green (G) and blue (B). The color of the color light emitted by the three sub-pixels is different from each other.
Referring to fig. 6, in particular, a driving method of a display panel includes:
s100, receiving a driving signal;
s200, judging whether the sub-pixels driven by the driving signals correspondingly are in a first area or a second area of the display screen;
s301, when the sub-pixel driven by the driving signal is in a first area, correcting the driving signal according to a preset mode;
s302, driving the corresponding sub-pixels of the first area by using the corrected driving signals;
and S311, when the pixel unit driven by the driving signal correspondingly is in a second area, driving the sub-pixel of the corresponding second area by using the driving signal.
As known from the AMOLED technology, the current flowing into each OLED pixel is controlled by the TFT array, so that the light intensity of each pixel point can be determined. In the embodiments provided by the present application, the light emitting intensity of the pixel unit can be controlled by the driving algorithm to improve the problem of brightness reduction caused by the blank area.
Specifically, the driving signal is received first. Then, the corresponding address information is looked up in the driving signal. Based on the address information, it is determined whether the sub-pixel driven by the driving signal is in the first area 100 or the second area 200. When the sub-pixel driven by the driving signal is in the first area 100, it is shown that the display brightness of the area may be low if the area is displayed normally. When the sub-pixel driven by the driving signal is in the second area 200, it is indicated that if the area is displayed normally, the display brightness may be normal, and no additional correction is needed. When the driving signal corresponds to the driven pixel unit or sub-pixel in the first area 100, the driving signal is modified according to a predetermined manner to generate a modified driving signal, and then the sub-pixel is driven to operate by using the modified driving signal. When the sub-pixel driven by the driving signal is in the second region 200, the driving signal is not modified, and the driving signal is directly used to drive the corresponding sub-pixel to operate.
Further, in another embodiment provided by the present application, the drive signal is modified in an arithmetic average or a weighted average.
Specifically, in the embodiments provided in the present application, since the sub-pixel sharing manner is adopted, the driving signals may not be processed for the non-shared sub-pixels, and one of the driving signals may be directly ignored for the shared sub-pixels, or may be directly superimposed in the summation manner, or may be superimposed in the arithmetic average manner after the summation, or may be superimposed in the weighted average manner according to a certain weight value. After the drive signal is corrected, the reduction of the display luminance due to the sub-pixel sharing can be reduced to some extent.
The present application also provides a driving algorithm, the first driving algorithm being a 1:2 algorithm and the other algorithm being a 3:4 algorithm. Specifically, referring to fig. 2 and 3, the subpixels shared in a common edge form, it can be seen that two subpixels are absent. Then, the driving signals of the remaining sub-pixels are calculated in units of 2 pixel units. For example, in fig. 3, the drive signal of one default blue subpixel and the drive signal of a non-default blue subpixel are calculated, and the drive signal corrected is calculated according to an algorithm, and then the common blue subpixel is driven to operate.
For a 3:4 drive algorithm, specifically, referring to fig. 4 and 5, the subpixels that are shared in a common vertex fashion, one subpixel can be seen by default. Then, the driving signals of the remaining sub-pixels are calculated in units of 4 pixel units. For example, in fig. 5, the drive signal of one default red subpixel and the drive signal of a red subpixel not default are calculated, and the drive signal corrected is calculated according to an algorithm, and then the common red subpixel is driven to operate. Here, the number of pixel units involved in the operation is 4.
Further, in an embodiment provided by the present application, there is also provided a display device including:
a display screen;
an under-screen light sensitive module capable of sensing light impinging through the display screen;
