In describing the components of the present invention, the terms first, second, A, B, (a), (b), and the like can be used. These terms are intended to distinguish the components from other components, and the terms do not limit the nature, order, order, or number of the components. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to the other component, Quot; intervening "or that each component may be" connected, "" coupled, "or " connected" through other components. An element or layer is referred to as being another element or layer "on ", including both intervening layers or other elements directly on or in between. The sizes and thicknesses of the respective components shown in the drawings are shown for convenience of explanation and the present invention is not limited to the sizes and thicknesses of the components shown.

An " organic light emitting device " which may be referred to herein as a " display device " is used as a general term for an organic light emitting diode panel and a display device employing such an organic light emitting diode panel. In general, there are two different types of organic light emitting display, white organic light emitting type and RGB organic light emitting type. In a white organic light emitting type, each subpixel of a pixel is configured to emit white light, and a set of color filters are used to filter the white light to produce red light, green light, and blue light in the corresponding subpixel. The white organic light emitting type may also include subpixels configured without a color filter to form subpixels for generating white light. In the RGB organic light emitting type, the organic light emitting layer in each subpixel is configured to emit light of a specified color. For example, one pixel includes a red subpixel having an organic light emitting layer emitting red light, a green subpixel having an organic light emitting layer emitting green light, and a blue subpixel having an organic light emitting layer emitting blue light .

It is to be understood that each of the features of the various embodiments of the present invention may be combined or combined with each other partially or totally and may be technically variously interlocked and driven by those skilled in the art and each embodiment may be implemented independently of one another, .

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

1A and 1B are conceptual diagrams illustrating a pixel repair method applied to an organic light emitting display panel.

The organic light emitting display device may include a plurality of pixels of the type shown in FIG. 1A. Here, one pixel 100 or 200 may have different colors (red (R), green (G), blue (B), and white (W), respectively.

In this case, when any one pixel or sub-pixel, for example, an R-sub-pixel 210 is defective due to a TFT (Thin Film Transistor) or a foreign object, a corresponding sub- , The TFT or anode electrode is cut and connected to the anode of the adjacent sub-pixel 110 to be repaired. In particular, in the large-area organic light-emitting display panel, anode or TFT wiring cutting and welding as described above are used for repairing the dark spot / bright spot. The cutting and welding method for repairing defective pixels can be performed because subpixels representing the same color are adjacent to each other.

Here, the repair may be performed during the panel manufacturing process before shipment of the product, or may be performed according to an after-sales service request from the customer after shipment of the product.

2A and 2B are a plan view and a sectional view showing the structure of a transparent pixel.

In the case of a pixel (hereinafter referred to as a transparent pixel) applied to a transparent organic light emitting display device, rendering is performed for ensuring transparency and reducing haze, or a case where subpixels of the same color are not disposed adjacent to each other It is common. For example, as shown in FIG. 2A, a pixel of a transparent organic light emitting display uses a structure in which a light emitting portion is gathered on one side of a pixel in order to maximize transmittance (transparency). That is, as shown in FIG. 2A, subpixels are arranged on one side (e.g., the left side) of the pixel and transparent regions are arranged on the other side (e.g., right side) of the pixel. In the case of such a pixel, although the pixels of the same structure are adjacent to each other, subpixels of the same color are not located adjacent to each other. In addition, due to the presence of the transparent region, the arrangement direction of the subpixels is different from the arrangement direction of the driving circuit for controlling each subpixel. 2A, the arrangement direction (vertical direction) of the subpixels 110, 120, and 130 and the arrangement direction (horizontal direction) of the driving circuits 115, 125, and 135 controlling each subpixel are different from each other Can be seen. Accordingly, it becomes very difficult to apply the pixel repair method described in Fig. 1 to the transparent pixel. That is, due to the structure of the transparent pixel, since the subpixels to be welded after cutting are not located close to each other, when a transistor or pixel electrode formed in any one of the subpixels has a problem, A constraint that can not be processed occurs.

The cross-sectional structure of the transparent pixel is shown in FIG. A buffer Buf, a TFT array, an insulating layer (PAS), a planarization layer (PAC 1, PAC 2) are stacked in this order on a substrate, and an anode electrode is formed on the planarization layer. The TFT array layer includes a source / drain electrode SD, a gate electrode Gate, a gate insulating film GI, and an active (ACT). An electrode may be positioned between the planarization layers and is used to connect the anode and the transistor electrode.

In the case where an auxiliary electrode is added to a transparent pixel, it is common to place another planarization layer for the convenience of arrangement of the auxiliary electrode and the conventional electrode (TFT electrode and anode electrode). Through this structure, design difficulties due to wiring crossing in the same plane are avoided. As a result, in order to form a transparent pixel including the auxiliary electrode, a TFT structure in which a planarization layer is applied twice is used.

3A and 3B are diagrams showing a pixel structure and a circuit configuration according to an embodiment of the present invention.

An organic light emitting display according to an embodiment of the present invention includes a pixel having a structure described below. The OLED display includes a display panel having a plurality of data lines, a plurality of gate lines, and a plurality of pixels; A data driver for outputting a data voltage to a plurality of data lines to drive the data lines; A gate driver for sequentially outputting scan signals to a plurality of gate lines to drive gate lines; A timing controller for outputting various control signals and controlling the data driver and the gate driver; And the like.

The data driver may include a plurality of data driver integrated circuits (also referred to as source driver integrated circuits), which may be a tape automated bonding (TAB) or a chip on glass (COG) (Bonding Pad) of the display panel, or may be directly formed on the display panel 110, or may be integrated on the display panel, as the case may be.

The gate driver may be located on only one side of the display panel according to the driving method, or may be located on both sides of the display panel divided into two. The gate driving unit may include a plurality of gate driving integrated circuits. The gate driving integrated circuits may be formed by bonding a display panel by using a tape automated bonding (TAB) method or a chip on glass (COG) A pad (Bonding Pad), or a GIP (Gate In Panel) type, and may be formed directly on the display panel, or may be integrated on the display panel as the case may be.

The embodiments of the present invention described below can be effectively applied to a top emission type organic light emitting display.

3A is a plan view illustrating a pixel structure according to an embodiment of the present invention. For convenience of explanation, it is assumed that the pixel is a transparent pixel including a transparent region. However, embodiments of the present disclosure may be applied to general pixels that do not include a transparent region.

The pixel 100 according to an embodiment of the present disclosure includes a plurality of sub-pixels, and the sub-pixels may be arranged in a specific direction on one side of the pixel. Although the plurality of subpixels 110, 120, 130, and 140 are illustrated as being arranged in the x and y directions in FIG. 3A, the subpixels may be arranged in order along the y direction.

The subpixels 110, 120, 130, and 140 may include a first region and a second region that emit light of the same color. For example, the red subpixel 110 is composed of two regions R (1/2) and R (2/2) as shown in FIG. 3A, and the blue subpixel 120 is composed of two regions of B 1/2) and B (2/2), and the green sub-pixel 130 is composed of two areas of G (1/2) and G (2/2) white) subpixel 140 is composed of two regions of W (1/2) and W (2/2).

That is, each subpixel has a structure divided into two (or more) regions. At this time, the separated regions (the first region and the second region) are arranged in a predetermined direction (first direction, y direction in FIG. 3A) in one subpixel. On the other hand, the transparent region in the pixel may be arranged in a second direction (e.g., a vertical direction, x direction in FIG. 3A) different from the first direction with respect to the subpixel.

The first region and the second region include a first driving circuit and a second driving circuit, respectively. In other words, the first driving circuit is connected to the first region to control the operation thereof, and the second driving circuit is connected to the second region to control the operation thereof. This connection relationship is conceptually shown in FIG. 3B. For example, two regions (R (1/2) and R (2/2)) of the red subpixel 110 are individually connected to the driving circuit. The other sub-pixels (G, B, W) are also the same.

The first driving circuit and the second driving circuit corresponding to the first region and the second region of a specific subpixel share a data line, a scan line, and a power supply voltage line. Although only the power supply voltage line VDD is shown in FIG. 3B, since the first region and the second region of a specific subpixel must exhibit the same color at the same timing, it is natural that the data line and the scan line must be shared .

If one of the subpixels separated into the first region and the second region occurs in bad (for example, a dark spot or a bad spot defect), the subpixel in this specification can interrupt the operation of the bad region through cutting. In this case, the subpixel in this specification is driven to be brighter in the normally driving region, so that the entire operation can be normalized. This process does not require welding, and will be described with reference to FIG. 3B.

For example, when a foreign object is present in the second region B (2/2) and the anode and the cathode are short-circuited to generate a dark spot, the C portion is cut and the luminance of the first region B (1/2) So that the total luminance can be made the same as before cutting. The C portion is between the driving circuit and the anode electrode, and may be, for example, between the source electrode of the driving transistor (n-type) and the anode electrode.

As another example, when a defective spot occurs due to an abnormality of the TFT corresponding to the first area W (1/2), the portion D is cut off and the brightness of the second area W (2/2) The luminance can be made the same as before cutting. The portion D may be between the power supply voltage line and the driving circuit, for example, between the power supply voltage line VDD and the drain electrode of the driving transistor (n-type).

A vision check may be used to detect the defective pixel (area). That is, the coordinates of the defective pixel (area) are detected through the vision inspection equipment. The detected defective pixels (regions) can be cut using laser equipment (laser cutting). The laser does not affect the organic / inorganic layer, but only the metal is subjected to thermal shock to cut the circuit.

4A and 4B are diagrams illustrating a pixel structure and a circuit configuration according to an embodiment of the present invention.

4A is a plan view illustrating a pixel structure according to an embodiment of the present invention. In FIG. 4A, unlike FIG. 3A, pixels in which R, G, and W subpixels 110, 130, and 140 are disposed are shown.

The subpixels 110, 130, and 140 may include a first region and a second region that emit light of the same color. For example, the red subpixel 110 is composed of two regions R (1/2) and R (2/2) as shown in FIG. 4A, and the green subpixel 130 is composed of two regions of G 1/2) and G (2/2), and the white sub-pixel 140 is composed of two regions of W (1/2) and W (2/2).

The first region and the second region include a first driving circuit and a second driving circuit, respectively. In this case, the first driving circuit and the second driving circuit may be located in an area occupied by the first area and the second area, respectively. That is, the first driving circuit is configured to be equal to or smaller than the horizontal area occupied by the first region R (1/2) of the red subpixel as shown in FIG. 4A, and is located above or below the first region . The driving circuit corresponding to the second region R (2/2) of the red subpixel may be arranged in the same manner, and the same applies to the driving circuits corresponding to the respective regions of the green subpixel and the white subpixel.

4B shows an example of the first driving circuit and the second driving circuit of the driving circuit. The first driving circuit may include a driving transistor DR-R-1, a switching transistor SW-R-1, and a capacitor C-R-1. The second driving circuit may include a driving transistor DR-R-2, a switching transistor SW-R-2, and a capacitor C-R-2. Each driving circuit is connected to an organic light emitting diode. The first driving circuit and the second driving circuit share the data line Data, the scan line Scan, and the power source voltage line VDD as shown in FIG. 4B, and are connected to the power source voltage line VDD in a cut-off manner.

When a defect (for example, a dark spot or a bright spot defect) occurs in one of the subpixels divided into the first area and the second area, the driving circuit of FIG. 4B can interrupt the operation of the defective area through cutting of the dotted line part . In this case, the uncut circuit can be controlled so that an increased amount of current flows before the other circuit is cut (that is, when all the drive circuits are normally connected). For example, after one of the driving circuits (for example, the second driving circuit) is cut, the value of the data (for example, Vdata) input through the data line to another circuit ), A larger amount of current flows to the other circuit (for example, the first driving circuit) than before the cutting. The operation adjustment of the other region according to the cut-off of one region described above can be performed by the data driver (for example, the data driver IC). That is, if the data driver detects that one of the subpixel regions (e.g., the second region) has been cut, It is possible to determine the operating condition (e.g., the amount of light emission) of the first region in which the subpixel can maintain the luminance before cutting by only the operation of another region (e.g., the first region) where the connection is maintained. Next, the data driver determines a data value (e.g., Vdata) corresponding to an operation condition of another area (e.g., a first area) where the connection is maintained; And transmit the determined data value to another area (e.g., a first area) where the connection is maintained. As a result, the data driver can control the subpixels so that the brightness of the entire subpixels becomes the same as before the cutting, because the other area (e.g., the first area) in which the connection is maintained emits brighter.

As a result, the amount of light emitted from the region (for example, the first region) corresponding to the other circuit (for example, the first driving circuit) increases, and as a result, the entire luminance of the subpixel can be kept constant before and after the cutting. The first driver circuit and the second driver circuit may be constituted by circuits (for example, 3T (transistor) + 1C (capacitor), 4T + 2C, etc.) . Such sensing (cutting of the specific driving circuit and / or anode voltage change) may also be performed in a data driver having a sensing circuit.

5 is a diagram illustrating the operation of subpixels according to an embodiment of the present invention.

In FIG. 5A, both the first region and the second region of the subpixel R normally operate. At this time, if a defect occurs in any one region (for example, the second region) as shown in FIG. 5 (b) and an abnormal operation is performed, the corresponding driving circuit is cut off and the luminance of the other region The overall operation of the subpixel can be normalized.

6A and 6B are views showing the structure of a pixel and an auxiliary wiring according to an embodiment of the present invention.

A pixel according to an embodiment of the present invention may further include an auxiliary electrode. The display device is required to have a uniform luminance over the entire panel, so that the variation of the power supply voltage (e.g., Vss) supplied to each pixel must be minimized. To this end, a structure in which an auxiliary electrode (Vss auxiliary electrode) is added to a pixel is often used. In the case of adding the auxiliary electrode to the transparent organic light emitting display, a further planarization layer is required for adding the auxiliary electrode due to restrictions on the arrangement of the subpixel and the transparent region, as described in FIG. 2B. However, in the pixel structure according to the embodiment of the present invention, an additional planarization layer for forming the auxiliary electrode is unnecessary. This will be described below.

The planar structure of a pixel according to an embodiment of the present invention is shown in FIG. The subpixels 110, 130, 140 are disposed on one side of the pixel 100. At this time, each sub-pixel is divided into two or more regions (for example, R (1/2) and R (2/2)) representing the same color. The regions are arranged in a first direction (e.g., the longitudinal direction in Fig. 6A) within one subpixel. The two or more regions may each include a corresponding drive circuit. The driving circuits may be located within an area (space) occupied by the corresponding area. That is, the driving circuit corresponding to R (1/2) (i.e., driving the R (1/2) region) has one region R (1/2) of the red subpixel 110 (The vertical direction in Fig. 6A) of the corresponding region

Also, the pixel 100 may have a transparent region on the other side. At this time, the transparent region is disposed in a remaining portion of the one pixel excluding the portion occupied by the subpixels. For example, with respect to the position of the subpixels, the transparent region is different from the direction (first direction) in which two or more regions are arranged in the subpixel And may be arranged in a second direction (e.g., the lateral direction in Fig. 6A).

While the auxiliary electrode may be arranged in the first direction on the plane. In FIG. 6A, the auxiliary electrode is shown as being located between subpixels and a transparent region, but may be located to the left of the subpixels 110, 130, 140 or to the right of the transparent region, according to an embodiment.

The stacked structure of pixels according to the embodiment of the present invention is shown in FIG.

A substrate is located at the bottom, and a buffer (Buf) is stacked on the substrate. A TFT array including the first driving circuit and a second driving circuit is formed on the buffer, and an insulating layer (PAS) is formed on the TFT array. A planarization layer (PAC) is formed on the passivation layer, and an anode electrode is formed on the planarization layer. The anode electrode is connected to a TFT (source or drain electrode). In such a laminated structure, a further planarizing layer for the arrangement of the auxiliary electrodes is unnecessary. As described above with reference to Fig. 6A, the anode electrode and the driving circuit (TFT or the like) constituting the specific region within the subpixel do not intersect with each other in the same layer as the auxiliary electrode because they are located within the horizontal area occupied by the specific region. Therefore, the auxiliary electrode can be formed on the same layer as the driving circuit, and a description thereof will be given below.

7 is a diagram illustrating embodiments of a pixel and an auxiliary electrode structure in accordance with embodiments of the present disclosure.

In the pixel structure according to the present specification, the auxiliary electrode (Vss auxiliary electrode) can be formed as shown in Figs. 7A to 7C. 7A and 7B illustrate a stacked structure of a pixel and a Vss auxiliary electrode. FIGS. 7B and 7C illustrate a pixel structure overlapping with FIG. 7A, Fig.

 The Vss auxiliary electrode may be formed on the same layer as the source-drain SD as shown in Fig. 7 (a), on the same layer as the anode as shown in Fig. 7 (b) drain (SD) and an anode as shown in FIG.

The first region and the second region represent the same color. To this end, the first driving circuit and the second driving circuit share a data line, a scan line, and a power supply voltage line. On the other hand, the first driving circuit and the second driving circuit are connected to the power supply voltage line so as to be capable of cutting. The first driving circuit may be configured such that when the second driving circuit is disconnected from the power supply voltage line, an increased current flows as compared to when the second driving circuit is connected to the power supply voltage line. As a result, the subpixel of the present invention can operate such that, if a defect occurs in one region, the corresponding region is disconnected in a circuit, and the other region compensates the defective region.
