Description

[0001] This application is a divisional application of the invention patent application filed on October 12, 2016, with application number "201610890130.6" and invention title "Organic Light Emitting Display Device". Technical Field

[0002] Exemplary embodiments of the present invention relate to an organic light-emitting display device and a method for manufacturing the organic light-emitting display device. More specifically, exemplary embodiments relate to an organic light-emitting display device having a mirror function and a touch function, and a method for manufacturing the organic light-emitting display device. Background Technology

[0003] Flat panel display (“FPD”) devices are widely used as display devices in electronic devices due to their lighter weight and thinner profile compared to cathode ray tube (“CRT”) display devices. Typical examples of flat panel display devices include liquid crystal display (“LCD”) devices and organic light-emitting diode (“OLED”) display devices. Compared to LCDs, OLEDs offer many advantages such as higher brightness and wider viewing angles. Furthermore, because OLED displays do not require backlighting, they can be manufactured to be thinner than LCDs. In OLED displays, electrons and holes are injected into a thin organic layer through the cathode and anode, where they recombine to generate excitons, thereby emitting light of a specific wavelength.

[0004] Recently, mirror-finish OLED devices have been developed, which reflect images of objects (or targets) located in front of the OLED device by including reflective components. In addition, OLEDs with both mirror and touch functions have been developed. Summary of the Invention

[0140] The invention will be explained in detail below with reference to the accompanying drawings. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals throughout denote the same elements.

[0141] What will be understood is that when a component is referred to as being "on" another component, the component can be directly on the other component, or there can be intermediate components in between. Conversely, when a component is referred to as being "directly on" another component, there are no intermediate components.

[0142] It will be understood that while the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, without departing from the teaching herein, the terms “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be designated as a second element, second component, second region, second layer, or second part.

[0143] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” (including “at least one”) are intended to include the plural forms. “Or” means “and / or”. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will also be understood that the terms “comprising” or “including” as used in this specification indicate the presence of the stated features, regions, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, regions, integrals, steps, operations, elements, components, and / or groups thereof.

[0144] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used here to describe the relationship between one element and another, as shown in the figures. It will be understood that relative terms are intended to include different orientations besides those depicted in the figures. In an exemplary embodiment, when the device in a figure is flipped, an element described as being “below” the other element will then be positioned “above” the other element. Depending on the specific orientation of the figure, the exemplary term “down” can therefore include both “below” and “up” orientations. Similarly, when the device in a figure is flipped, an element described as being “below” or “under” the other element will then be positioned “above” the other element. The exemplary terms “below” or “under” can therefore include both “above” and “below” orientations.

[0145] As used herein, “approximately” includes the stated value and means: within an acceptable range of deviation from the specific value as determined by one of ordinary skill in the art, taking into account the measurement being discussed and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, “approximately” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value.

[0146] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will also be understood that, unless expressly defined herein, terms (such as those defined in a common dictionary) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and in this invention, and not as having an idealized or overly formal meaning.

[0147] Exemplary embodiments are described herein with reference to cross-sectional views, which are schematic representations of idealized embodiments. Thus, variations in the illustrated shape are expected, for example, due to manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but will include, for example, deviations in shape due to manufacturing processes. In exemplary embodiments, regions shown or described as flat generally have rough and / or non-linear characteristics. Furthermore, acute angles shown may be rounded. Therefore, the regions shown in the figures are purely schematic, and their shapes are not intended to represent the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0148] Figure 1 This is a plan view illustrating an organic light-emitting display device according to an exemplary embodiment of the present invention. Figure 2 It is along Figure 1 The sectional view taken from line II′.

[0149] Reference Figure 1 and Figure 2 An organic light-emitting display device according to an exemplary embodiment of the present invention may include a light-emitting region II and a reflective region III. Pixels 60, 70, and 80 may be located in the light-emitting region II, and a transparent window may be located in the reflective region III. In an exemplary embodiment, for example, pixel 60 may be a pixel emitting red, pixel 70 may be a pixel emitting green, and pixel 80 may be a pixel emitting blue.

[0150] A reflective member may be disposed in the light-emitting region II and the reflective region III. The reflective member may include a first reflective member disposed in the reflective region III and a second reflective member disposed in both the light-emitting region II and the reflective region III. The first reflective member may have a different reflectivity than the second reflective member. When the reflective member only includes the first reflective member, scattered reflection occurs at the edge of the first reflective member. However, the organic light-emitting display device according to an exemplary embodiment of the present invention includes a second reflective member disposed in both the light-emitting region II and the reflective region III. Therefore, scattered reflection occurring at the edge of the first reflective member can be reduced. In other exemplary embodiments, the first reflective member may be superimposed on a portion of pixels 60, 70, and 80. The first reflective member is disposed outside pixels 60, 70, and 80, such that the first reflective member can be superimposed on a portion of pixels 60, 70, and 80.

[0151] According to an exemplary embodiment of the present invention, the first reflective member may be a first sensing electrode 370 comprising a material having a predetermined reflectivity. Additionally, according to an exemplary embodiment of the present invention, the second reflective member may be a second sensing electrode 390 comprising a material having a predetermined reflectivity and sensing a touch position. The first sensing electrode 370 may be stacked with the second sensing electrode 390.

[0152] The first sensing electrode 370 and the second sensing electrode 390 can be implemented as sensing electrodes of a mutual capacitance type touchscreen panel. In an exemplary embodiment, for example, when an electrical conductor is touched, the capacitance of the first sensing electrode 370 and the second sensing electrode 390 around the intersection point of the touch position changes. Therefore, the touch panel sensor (not shown) can determine the touch position based on the capacitance sensing signal corresponding to the change in capacitance.

[0153] The first sensing electrode 370 may have a different thickness than the second sensing electrode 390. In an exemplary embodiment, the thickness of the first sensing electrode 370, measured along the cross-sectional direction, may be, for example, approximately 1000 angstroms. When the thickness of the first sensing electrode 370 is approximately At this time, the transmittance of the first sensing electrode 370 can be approximately 0% (0%), and the reflectance of the first sensing electrode 370 can be greater than approximately 95%. Additionally, the thickness of the second sensing electrode 390, measured along the cross-sectional direction, can be approximately... When the thickness of the second sensing electrode 390 is approximately At this time, the transmittance of the second sensing electrode 390 can be greater than about 50% and less than about 95%. When the organic light-emitting display device emits light, light is emitted through the second sensing electrode 390 in the light-emitting region II. When the organic light-emitting display device does not emit light, the second sensing electrode 390 can perform a mirror function.

[0154] An organic light-emitting display device according to an exemplary embodiment of the present invention includes a first substrate 110, a buffer layer 115, a first insulating layer 150, a second insulating layer 190, a third insulating layer 270, a light-emitting structure, a pixel defining layer 310, a first sensing electrode 370, a second sensing electrode 390, and a second substrate 350. Here, the light-emitting structure includes a semiconductor element 250, a first electrode 290, a light-emitting layer 330, and a second electrode 340. The semiconductor element 250 includes an active pattern (active layer) 130, a gate electrode 170, a source electrode 210, and a drain electrode 230. An opening 380 is defined in the first sensing electrode 370.

[0155] Organic light-emitting display device 100 may include multiple pixel regions Px (refer to...) Figure 12 A pixel region may include a light-emitting region II and a reflective region III. The reflective region III may substantially surround the light-emitting region II. A portion of the semiconductor element 250, the first electrode 290, the light-emitting layer 330, and the second electrode 340 may be disposed in the light-emitting region II. However, the invention is not limited thereto, and the semiconductor element 250 may also be disposed in the reflective region III. Additionally, the first sensing electrode 370 may be disposed in the reflective region III and outside the light-emitting region II, and the second sensing electrode 390 may be disposed in both the light-emitting region II and the reflective region III.

[0156] The image can be displayed in the luminescent area II. The image of an object located in front of the organic light-emitting display device 100 can be reflected in the reflective area III.

[0157] A light-emitting structure can be disposed on a first substrate 110. The first substrate 110 may include a transparent material. In an exemplary embodiment, the first substrate 110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 110 may include a flexible transparent resin substrate. Here, the flexible transparent resin substrate for the first substrate 110 may include a polyimide substrate. In an exemplary embodiment, the polyimide substrate may include, for example, a first polyimide layer, a barrier film layer, a second polyimide layer, etc. When the polyimide substrate is thin and flexible, the polyimide substrate may be disposed on a rigid glass substrate to help support the formation of the light-emitting structure. That is, in an exemplary embodiment, the first substrate 110 may have a structure in which a first polyimide layer, a barrier film layer, and a second polyimide layer are stacked on a glass substrate.

[0158] After the light-emitting structure is disposed on the insulating layer, the glass substrate can be removed. Because the polyimide substrate is thin and flexible, it may be difficult to directly dispose of the light-emitting structure on it. Therefore, the light-emitting structure is disposed on a rigid glass substrate, and then, after removing the glass substrate, the polyimide substrate can be used as the first substrate 110. Because the organic light-emitting display device 100 includes a light-emitting region II and a reflective region III, the first substrate 110 may also include a light-emitting region II and a reflective region III.

[0159] A buffer layer 115 may be disposed on the first substrate 110. The buffer layer 115 may extend from the light-emitting region II into the reflective region III. The buffer layer 115 may prevent metal atoms and / or impurities from diffusing from the first substrate 110 (e.g., venting). In addition, the buffer layer 115 may control the heat transfer rate in the crystallization process used to form the active pattern 130, thereby obtaining a substantially uniform active pattern 130. Furthermore, when the surface of the first substrate 110 is relatively irregular, the buffer layer 115 may improve the surface flatness of the first substrate 110. Depending on the type of the first substrate 110, at least two buffer layers may be disposed on the first substrate 110, or no buffer layer may be disposed.

[0179] Reference Figure 3 A buffer layer 115 is disposed on the first substrate 110. Then, an active pattern 130 and a first insulating layer 150 are disposed on the buffer layer 115.

[0180] In an exemplary embodiment, the first substrate 110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc.

[0181] A light-emitting structure can be formed on a first substrate 110. The first substrate 110 may include a transparent material. In an exemplary embodiment, the first substrate 110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 110 may include a flexible transparent resin substrate. Here, the flexible transparent resin substrate for the first substrate 110 may include a polyimide substrate. In an exemplary embodiment, the polyimide substrate may include, for example, a first polyimide layer, a barrier film layer, a second polyimide layer, etc. When the polyimide substrate is thin and flexible, a polyimide substrate may be formed on a rigid glass substrate to help support the formation of the light-emitting structure.

The buffer layer 115 can prevent metal atoms and / or impurities from diffusing from the first substrate 110 (e.g., venting). In addition, the buffer layer 115 can control the heat transfer rate in the crystallization process used to form the active pattern 130, thereby obtaining a substantially uniform active pattern 130. Furthermore, when the surface of the first substrate 110 is relatively irregular, the buffer layer 115 can improve the surface flatness of the first substrate 110.

[0246] Figures 27 to 33 It shows the manufacturing process. Figure 26 A cross-sectional view of a method for developing an organic light-emitting display device.

[0247] Reference Figure 27A buffer layer 1115 is disposed on the first substrate 1110. Then, an active pattern 1130 and a first insulating layer 1150 are disposed on the buffer layer 1115.

[0248] In an exemplary embodiment, the first substrate 1110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc.

[0249] A light-emitting structure can be formed on a first substrate 1110. The first substrate 1110 may include a transparent material. In an exemplary embodiment, the first substrate 1110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 1110 may include a flexible transparent resin substrate. Here, the flexible transparent resin substrate for the first substrate 1110 may include a polyimide substrate. In an exemplary embodiment, the polyimide substrate may include, for example, a first polyimide layer, a barrier film layer, a second polyimide layer, etc. When the polyimide substrate is thin and flexible, a polyimide substrate may be formed on a rigid glass substrate to help support the formation of the light-emitting structure. That is, in an exemplary embodiment, the first substrate 1110 may have a structure in which a first polyimide layer, a barrier film layer, and a second polyimide layer are stacked on a glass substrate. Here, after the insulating layer is provided on the second polyimide layer, a light-emitting structure (e.g., semiconductor element 1250, capacitor, first electrode 1290, light-emitting layer 1330, second electrode 1340, etc.) can be provided on the insulating layer.

[0250] After the light-emitting structure is formed on the insulating layer, the glass substrate can be removed. Because the polyimide substrate is thin and flexible, it may be difficult to form the light-emitting structure directly on the polyimide substrate. Therefore, the light-emitting structure is formed on a rigid glass substrate, and then the polyimide substrate can be used as the first substrate 1110 after the glass substrate is removed. Because the organic light-emitting display device 1100 includes a light-emitting region II and a reflective region III, the first substrate 1110 can also include a light-emitting region II and a reflective region III.

[0251] A buffer layer 1115 can be disposed on the first substrate 1110. The buffer layer 1115 can extend from the light-emitting region II into the reflective region III. The buffer layer 1115 can prevent metal atoms and / or impurities from diffusing from the first substrate 1110 (e.g., venting). In addition, the buffer layer 1115 can control the heat transfer rate in the crystallization process used to form the active pattern 1130, thereby obtaining a substantially uniform active pattern 1130. Furthermore, when the surface of the first substrate 1110 is relatively irregular, the buffer layer 1115 can improve the surface flatness of the first substrate 1110. Depending on the type of the first substrate 1110, at least two buffer layers can be disposed on the first substrate 1110, or no buffer layer may be disposed.

[0316] Reference Figure 51 A buffer layer 2115 is disposed on the first substrate 2110. Then, an active pattern 2130 and a first insulating layer 2150 are disposed on the buffer layer 2115.

[0317] In an exemplary embodiment, the first substrate 2110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc.

[0318] A light-emitting structure can be formed on a first substrate 2110. The first substrate 2110 may include a transparent material. In an exemplary embodiment, the first substrate 2110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 2110 may include a flexible transparent resin substrate. Here, the flexible transparent resin substrate for the first substrate 2110 may include a polyimide substrate. In an exemplary embodiment, the polyimide substrate may include, for example, a first polyimide layer, a barrier film layer, a second polyimide layer, etc. When the polyimide substrate is thin and flexible, a polyimide substrate may be formed on a rigid glass substrate to help support the formation of the light-emitting structure. That is, in an exemplary embodiment, the first substrate 2110 may have a structure in which a first polyimide layer, a barrier film layer, and a second polyimide layer are stacked on a glass substrate.

[0319] After the light-emitting structure is formed on the insulating layer, the glass substrate can be removed. Because the polyimide substrate is thin and flexible, it may be difficult to form the light-emitting structure directly on the polyimide substrate. Therefore, the light-emitting structure is formed on a rigid glass substrate, and then the polyimide substrate can be used as the first substrate 2110 after the glass substrate is removed. Because the organic light-emitting display device 2100 includes a light-emitting region II and a reflective region III, the first substrate 2110 can also include a light-emitting region II and a reflective region III.

The buffer layer 2115 can prevent metal atoms and / or impurities from diffusing from the first substrate 2110 (e.g., venting). In addition, the buffer layer 2115 can control the heat transfer rate in the crystallization process used to form the active pattern 2130, thereby obtaining a substantially uniform active pattern 2130. Furthermore, when the surface of the first substrate 2110 is relatively irregular, the buffer layer 2115 can improve the surface flatness of the first substrate 2110. Depending on the type of the first substrate 2110, at least two buffer layers can be disposed on the first substrate 2110, or no buffer layer may be disposed.

[0386] Reference Figure 76 A buffer layer 3115 is disposed on the first substrate 3110. Then, an active pattern 3130 and a first insulating layer 3150 are disposed on the buffer layer 3115.

[0387] In an exemplary embodiment, the first substrate 3110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc.

[0388] A light-emitting structure can be formed on a first substrate 3110. The first substrate 3110 may include a transparent material. In an exemplary embodiment, the first substrate 3110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 3110 may include a flexible transparent resin substrate. Here, the flexible transparent resin substrate for the first substrate 3110 may include a polyimide substrate. In an exemplary embodiment, the polyimide substrate may include, for example, a first polyimide layer, a barrier film layer, a second polyimide layer, etc. When the polyimide substrate is thin and flexible, a polyimide substrate may be formed on a rigid glass substrate to help support the formation of the light-emitting structure. That is, in an exemplary embodiment, the first substrate 3110 may have a structure in which a first polyimide layer, a barrier film layer, and a second polyimide layer are stacked on a glass substrate.

[0389] After the light-emitting structure is formed on the insulating layer, the glass substrate can be removed. Because the polyimide substrate is thin and flexible, it may be difficult to form the light-emitting structure directly on the polyimide substrate. Therefore, the light-emitting structure is formed on a rigid glass substrate, and then the polyimide substrate can be used as the first substrate 3110 after the glass substrate is removed. Because the organic light-emitting display device 3100 includes a light-emitting region II and a reflective region III, the first substrate 3110 can also include a light-emitting region II and a reflective region III.

[0390] A buffer layer 3115 can be disposed on the first substrate 3110. The buffer layer 3115 can extend from the light-emitting region II into the reflective region III. The buffer layer 3115 can prevent metal atoms and / or impurities from diffusing from the first substrate 3110 (e.g., venting). In addition, the buffer layer 3115 can control the heat transfer rate in the crystallization process used to form the active pattern 3130, thereby obtaining a substantially uniform active pattern 3130. Furthermore, when the surface of the first substrate 3110 is relatively irregular, the buffer layer 3115 can improve the surface flatness of the first substrate 3110. Depending on the type of the first substrate 3110, at least two buffer layers can be disposed on the first substrate 3110, or no buffer layer may be disposed.

[0460] Figures 101 to 108 It shows the manufacturing process. Figure 100 A cross-sectional view of a method for developing an organic light-emitting display device.

[0461] Reference Figure 101 A buffer layer 4115 is disposed on the first substrate 4110. Then, an active pattern 4130 and a first insulating layer 4150 are disposed on the buffer layer 4115.

[0462] In an exemplary embodiment, the first substrate 4110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc.

[0463] A light-emitting structure can be formed on a first substrate 4110. The first substrate 4110 may include a transparent material. In an exemplary embodiment, the first substrate 4110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 4110 may include a flexible transparent resin substrate. Here, the flexible transparent resin substrate for the first substrate 4110 may include a polyimide substrate. In an exemplary embodiment, the polyimide substrate may include, for example, a first polyimide layer, a barrier film layer, a second polyimide layer, etc. When the polyimide substrate is thin and flexible, a polyimide substrate may be formed on a rigid glass substrate to help support the formation of the light-emitting structure. That is, in an exemplary embodiment, the first substrate 4110 may have a structure in which a first polyimide layer, a barrier film layer, and a second polyimide layer are stacked on a glass substrate. Here, after the insulating layer is provided on the second polyimide layer, a light-emitting structure (e.g., semiconductor element 4250, capacitor, first electrode 4290, light-emitting layer 4330, second electrode 4340, etc.) can be provided on the insulating layer.

[0464] After the light-emitting structure is formed on the insulating layer, the glass substrate can be removed. Because the polyimide substrate is thin and flexible, it may be difficult to form the light-emitting structure directly on the polyimide substrate. Therefore, the light-emitting structure is formed on a rigid glass substrate, and then the polyimide substrate can be used as the first substrate 4110 after the glass substrate is removed. Because the organic light-emitting display device 4100 includes a light-emitting region II and a reflective region III, the first substrate 4110 can also include a light-emitting region II and a reflective region III.

[0465] A buffer layer 4115 can be disposed on the first substrate 4110. The buffer layer 4115 can extend from the light-emitting region II into the reflective region III. The buffer layer 4115 can prevent metal atoms and / or impurities from diffusing from the first substrate 4110 (e.g., venting). In addition, the buffer layer 4115 can control the heat transfer rate in the crystallization process used to form the active pattern 4130, thereby obtaining a substantially uniform active pattern 4130. Furthermore, when the surface of the first substrate 4110 is relatively irregular, the buffer layer 4115 can improve the surface flatness of the first substrate 4110. Depending on the type of the first substrate 4110, at least two buffer layers can be disposed on the first substrate 4110, or no buffer layer may be disposed.

[0540] In an exemplary embodiment, the first substrate 5110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc.

[0541] A light-emitting structure can be formed on a first substrate 5110. The first substrate 5110 may include a transparent material. In an exemplary embodiment, the first substrate 5110 may include, for example, quartz, artificial quartz, calcium fluoride, fluorine-doped quartz, soda-lime glass, alkali-free glass, etc. In an alternative exemplary embodiment, the first substrate 5110 may include a flexible transparent resin substrate.
