Description
Technical Field
The invention relates to the technical field of display, in particular to an organic light emitting diode display device and a manufacturing method thereof.
Background
With the rapid progress of display technology, semiconductor device technology, which is the core of display devices, has also been dramatically advanced. For the conventional display device, an Organic Light Emitting Diode (OLED), as a current type Light emitting device, is increasingly applied to the field of high performance display due to its characteristics of self-luminescence, fast response, wide viewing angle, and convenience for manufacturing on a flexible substrate.
In the design of the OLED display device, in order to reduce the visual quality reduction caused by reflection under strong light conditions, the prior art generally uses a circular polarizer attached to the display end, and external light passes through the circular polarizer to form polarized light. The polarized light is reflected by the reflecting electrode of the OLED to form reverse polarization, so that the polarized light cannot penetrate out of the circular polarizing plate and enter human eyes. Therefore, the reflectivity can be greatly reduced, and the display performance under indoor and outdoor strong light is further ensured. Meanwhile, in order to have a Touch control function, in the prior art, a package of a Touch Sensor Panel (TSP) is generally packaged in a device, so as to achieve the purpose of the Touch control function.
However, the transmittance of the conventional circular polarizer is only about 42%, which means that nearly 60% of the light emitted from the OLED is blocked by the circular polarizer, and this problem causes the power consumption of the OLED to be too high. Meanwhile, the OLED needs to emit required light intensity with a current density 2.5 times, which may cause too short lifetime of the OLED, and also may cause side effects such as excessive heating of Integrated Circuit (IC) current, and easy damage of components. In addition, the external touch screen has great influence on the lightness and thinness of the display screen, and the display effect can be influenced to a certain extent.

Detailed Description
Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The invention provides an organic light emitting diode display device and a manufacturing method thereof, which can realize dual functions of polarization and an externally-hung touch screen by improving a process of packaging glass on the basis of the prior art, thereby reducing the manufacturing cost to a certain extent and further realizing the light and thin function.
Example one
Embodiments of the present invention provide a method for manufacturing an organic light emitting diode display device, including, for example, an active organic light emitting diode display device. Referring to fig. 1, the method includes the steps of:
step S100, providing a substrate, and forming a first conductive layer on one side of a light-emitting surface of the substrate;
in this step, a substrate is provided first, and a first conductive layer is formed above the substrate (on the light emitting surface side), where the first conductive layer may be, for example, a patterned metal layer or an ITO layer. The above-mentioned "above the substrate" includes a case of directly contacting the substrate, and also includes a case of being located above the substrate but not contacting the substrate, for example, contacting a functional layer above the substrate.
The first conductive layer is formed by forming a first conductive material layer on one side of the light-emitting surface of the substrate and forming a patterned first conductive layer through a patterning process.
For example, referring to fig. 2, the step of providing a substrate and forming a first conductive layer on the substrate includes:
in the substep S101, a substrate is provided, and a first conductive material layer is formed on one side of the light emitting surface of the substrate.
In this step, a conductive material may be deposited over the substrate, for example by depositing a first layer of conductive material on the substrate.
In the sub-step S102, a first conductive layer including a first specific pattern is formed on the first conductive material layer through a patterning process.
The patterning process generally includes processes such as photoresist coating, exposure, development, etching, and photoresist stripping.
Specifically, for the sub-steps, the substrate is, for example, a package glass, the first conductive material layer is, for example, a metal layer or an ITO (indium tin oxide) layer, and after the first conductive material layer is deposited on the package glass, a trace (a first specific pattern) is formed in the pixel region of the first conductive material layer through a photolithography and etching process. This process is responsible for designing the pattern, i.e., in short, leaving a useful conductive layer and removing a useless conductive layer to obtain a pattern in accordance with the design pattern. The photolithography and etching process is one of the key processes in the manufacturing process of the liquid crystal display. For example, in the case of an ITO layer, photolithography is to coat a photosensitive resist on a conductive glass, expose the conductive glass, and then selectively chemically etch the ITO layer by using the protective effect of the photosensitive resist, thereby obtaining a pattern corresponding to the mask on the ITO layer.
In addition, the etching technique is a technique of selectively etching or peeling a surface of a semiconductor substrate or a surface coating film according to a mask pattern or design requirements. For the ITO layer, for example, after the photoetching process is finished, the etching is to etch off the ITO film on the glass which is not protected by the photoresist by using a certain proportion of acid liquor, and to preserve the ITO film protected by the photoresist, so as to finally form an ITO pattern. The selected corrosive liquid must be capable of corroding the ITO film and not damaging the glass surface and the photoresist, low-temperature ITO is generally selected, and a certain proportion of HNO is adopted as the corrosive liquid3、H3PO4And water. Since the wet etching utilizes a chemical reaction to remove the thin film, the chemical reaction itself is not directional, and thus the wet etching process is isotropic. The wet etching adopted in the microelectronic manufacturing process has the advantages of low cost, high reliability, high yield, excellent etching selection ratio and the like.
In practical application, after the photolithography and etching process is finished, the method further comprises the steps of removing photoresist and cleaning. Specifically, photoresist removal is to remove the residual photoresist on the etched ITO conductive glass, and cleaning is to wash the residual photoresist, impurities and the like on the surface of the glass. The stripping solution is prepared by using alkali solution, and the alkali concentration of the stripping solution is higher than the developing concentration. The cleaning is to wash residual alkali liquor on the glass with high-purity water and wash residual glue at the same time.
After the photolithography and etching steps, the first conductive layer is formed as a patterned conductive layer. The first conductive layer may include a first alignment mark thereon for aligning with a subsequent conductive layer.
Step S200, forming an insulating polarization layer on one side, far away from the substrate, of the first conductive layer, wherein the insulating polarization layer comprises particles with polarization characteristics.
For the above steps, the insulating polarizing layer is, for example, an organic polymer layer having particles of polarizing characteristics, and the insulating polarizing layer may adjust the polarizing characteristics of the insulating layer by adjusting the size, density, and the like of the added nanoparticles. The practical application comprises the following two implementation modes for different process levels:
the first mode adopts the idea of taking the nano particles as a layer to be independently arranged, and specifically comprises the following steps:
step S201a, forming a first insulating layer on a side of the first conductive layer away from the substrate;
step S201b, arranging a polarization layer on one side of the first insulating layer far away from the first conductive layer, wherein the polarization layer comprises particles with polarization characteristics;
step S201c, forming a second insulating layer on a side of the polarizing layer away from the first insulating layer.
For the above steps, a layer of organic polymer is formed on the first conductive layer, and then a layer of particles with polarization characteristics, such as nanoparticles, specifically, iodine particles or graphene particles, is disposed on the first conductive layer; then forming a layer of organic polymer on the nano particles; wherein the process of disposing the nanoparticle layer may form the polarizing layer by coating the particles having the polarizing property on the first insulating layer by, for example, injection or spraying.
By adopting the mode, the requirement on the process control level is not high, and the implementation mode is relatively intuitive; in addition, the polarization characteristics of the insulating layer are adjusted by adjusting the size, density, etc. of the added nanoparticles during the process of injecting or spraying the nanoparticles.
The second way includes:
step S202a, mixing the particles with polarization characteristic with insulating material to form an insulating polarization composition;
step S202b, disposing the insulating polarizing composition on a side of the first conductive layer away from the substrate to form an insulating polarizing layer.
For example, before forming the organic polymer, the nanoparticles are directly mixed into the organic polymer to prepare a mixed organic polymer mixed with the nanoparticles, and then the mixed organic polymer is coated on the first conductive layer as a coating; the second implementation has higher requirements on the stability of the process control of the mixed organic polymer and the nanoparticles, but once the mixing is successful, the coating process is simple and can be completed in one step; in addition, the mode can realize the adjustment of the polarization characteristic of the insulating layer by adjusting the size, the density and the like of the added nano particles in the mixing process.
For an insulating polarizing layer formed of an organic polymer, the step of forming an insulating polarizing layer on the first conductive layer is divided into two steps, i.e., coating and curing. Before the next operation, namely coating the second conductive layer, of the insulating polarizing layer made of the organic polymer, a certain time is needed for curing to enable the hardness of the insulating polarizing layer to meet the process requirement, so that the problem of subsequent process errors caused by insufficient hardness of the insulating polarizing layer is solved.
Step S300, forming a second conductive layer on one side of the insulating polarization layer far away from the first conductive layer.
The step of forming a second conductive layer on the insulating polarizing layer includes:
substep S301, forming a second conductive material layer on a side of the insulating polarization layer away from the first conductive layer;
in the substep S302, a second conductive layer including a second specific pattern is formed on the second conductive material layer through a patterning process.
The substeps described above may refer to substeps S101 to S102, which are not described herein again.
Similarly, after the photolithography and etching steps, the second conductive layer is formed as a patterned conductive layer, that is, another trace (a second specific pattern) different from the trace in the first conductive layer is formed in the pixel region of the second conductive material layer. The second conductive layer may include a second alignment mark thereon for aligning with other conductive layers.
Notably, the first specific pattern and the second specific pattern form a network, and the network is used for determining the coordinates of a specific position; the first conductive layer comprises a first set of electrodes and the second conductive layer comprises a second set of electrodes such that when a voltage is applied to an electrode, a voltage gradient is formed across the network. Wherein, the electrode is made of material with excellent conductivity (such as silver powder ink), and the conductivity of the electrode is about 1000 times of that of ITO.
In this way, the network formed by the traces on the first and second conductive layers implements the touch function, and the specific implementation process includes: when the touch screen works, the upper conductor layer and the lower conductor layer are equivalent to a resistor network, and when a voltage is applied to one electrode, a voltage gradient is formed on the network. If an external force causes the first conductive layer to contact the second conductive layer at a certain point, the voltage at the contact point can be measured at another layer to which no voltage is applied to the electrodes, so that the coordinates at the contact point can be known. For example, when a voltage is applied to the first group of electrodes of the second conductive layer, a voltage gradient is formed on the second conductive layer, when an external force is applied, the first and second conductive layers are in contact at a certain point, the voltage at the contact point can be measured on the first conductive layer, and then the coordinate of the first direction at the point is obtained according to the direct distance relationship between the voltage and the electrodes. The voltage is then switched to the first set of electrodes and the voltage at the point of contact is measured at the second conductive layer, thereby obtaining the coordinates of the second direction. In the rectangular plane coordinate system, the specific position of the contact point can be determined by the coordinates in the first direction and the coordinates in the second direction.
It should be noted that there are many ways to implement the touch screen structure in the art, and the above is only one embodiment, which is used for illustration and is not particularly limited.
In addition, the OLED can be classified into a PMOLED (Passive Matrix Driving OLED) and an AMOLED (Active Matrix Driving OLED/Active organic light emitting diode) according to a Driving method. Therefore, the method of fabricating the organic light emitting diode display device may be applied to at least an active organic light emitting diode display device.

Next, polarizing particles are added to the insulating layer and the particles are cured, for example, particles of nano-iodine, graphene, etc. are added to the polymer insulating layer, nanoparticles are cured in the polymer insulating layer by, for example, coating-curing, and the polarizing ability is adjusted by the size, density, etc. of the added nanoparticles.
Third, a first insulating layer (a layer of organic polymer) is provided on the first conductive layer, a polarizing layer (nanoparticles having a polarizing property such as iodine or graphene) is formed thereon by an injection or spray process, and a second insulating layer (another layer of organic polymer) is formed on the polarizing layer. In the process of forming the insulating layer by layers, the nanoparticles are sprayed or injected into the formed insulating layer as a layer, and then the insulating layer is continuously formed on the upper part of the nanoparticle layer. The realization process has low requirements on the process and low cost.
In addition, the method for directly coating the organic polymer layer by mixing the nano particles into the organic polymer layer has high requirement on the stability of process control, but the coating process is simple and convenient to operate.
