In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The component names used in the following description may be selected in consideration of ease of specification, and may be different from the component names of the organic light emitting display devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

The organic light emitting display according to the embodiment of the present invention will be described in detail. 2A, a signal transfer film 33 connected to the first substrate 11 on a side surface of the first substrate 11 for applying a signal and / or a power required for display implementation is formed . A seating part SS for positioning at least a part of the signal transfer film 33 is formed on the second substrate 22.

Although not shown, a pixel portion (not shown) for implementing a display is formed on the first substrate 11, a thin film transistor (not shown) for driving each of the pixel portions is formed, An organic light emitting layer (not shown) for light emission is formed. In general, the circuit portion of the organic light emitting display device may include a driving transistor (not shown) for driving the organic light emitting layer, and a switching transistor (not shown) for controlling the driving transistor. In addition, additional transistors (not shown) and capacitors (not shown) may be additionally formed to carry out appropriate signal transmission and compensation of the driving transistor. In order to control the pixel portion, a data signal line (not shown) for applying a data signal, a scan signal line (not shown) for applying a scan signal and a specific power source are applied to each pixel portion on the first substrate 11 (Not shown). At this time, since a plurality of transistors, capacitors, and the like are included in each pixel portion formed on the first substrate 11, a plurality of power sources having different voltages are required. In general, a high potential voltage, a low potential voltage, and a reference voltage Vref may be applied to the panel, and different power lines may be formed on the first substrate 11 to supply the different voltages. have.

In addition, the organic light emitting layer (not shown) may be formed between a first electrode (not shown) and a second electrode (not shown) formed on the first substrate 11. A protective layer (not shown) may be additionally formed on the organic light emitting layer to protect the organic material from moisture and oxygen. The organic light emitting layer may include a hole injection layer, a hole transporting layer, a light emitting layer, an electron transporting layer, and an electron injection layer. The organic light emitting layer may further include a functional layer for improving the luminous efficiency and / have. The organic light emitting layer may have a single layer of a light emitting material layer emitting a specific color, but may be formed by stacking a plurality of light emitting layers emitting a specific color. When a light emitting layer is formed by stacking several layers, generally, the light emitting layer emits white light, and a separate color filter is further formed around the first substrate 11 or the second substrate 22 to display a color Can be reproduced.

The second substrate 22 of the OLED display according to the embodiment of the present invention may be formed of glass, metal, or plastic. At this time, the second substrate 22 physically and chemically protects the organic light emitting layer and the protective layer formed on the first substrate 11. In general, when the first substrate 11 and the second substrate 22 are formed of glass, they have the same properties as each other because they are made of the same material. In addition, when formed of metal, the second substrate 22 can be thinner and lighter than the glass, and the second substrate 22 can be formed at a lower cost than glass. When the first substrate 11 is formed of glass, the second substrate 22 may be formed of an alloy having a thermal expansion coefficient substantially equal to that of the first substrate 11. When the first substrate 11 and the second substrate 22 are formed of plastic, the organic light emitting display device itself has flexibility and a flexible display can be realized. At this time, the second substrate 22 should generally be formed smaller than the first substrate 11. This is because the signal transmission pad (not shown) and / or the power application unit (not shown) formed on the first substrate 11 must be electrically connected to the signal transfer film 33. Since the signal transmission pad for connection with the signal transfer film 33 is formed on the periphery of the display region or at least the non-display region on the first substrate 11, the region must be opened, The second substrate 22 should be formed smaller than the substrate 11. [

2A and 2B, signal transmission pads are formed on the first substrate 11 on the periphery of the display area or on the non-display area. At least one end of the signal transmission pad is electrically connected to the signal transmission film 33. At this time, an end region of at least one surface of the second substrate 22 is formed to be stepped with the central region of the second substrate 22 to form a seating portion SS. At least one end region of the second substrate 22 may be formed as a side groove to form a seating part SS. At this time, at least a part of the signal transfer film 33 can be stably positioned at the seating part SS and can be stably placed in the seating part SS.

The second substrate 22 of the OLED display according to the embodiment of the present invention may include a seating part SS. The seating part SS accommodates at least a part of the signal transmission film 33 to help the signal transmission film 33 to be fixed. In addition, it facilitates alignment or alignment of the signal transmission film 33 required in the manufacturing process of the OLED display according to the present embodiment. The seating part SS provides an internal space for positioning the signal transfer film 33 so that the signal transfer film 33 is not exposed above the second substrate 22, Do not cause physical interference with parts.

2A shows a seating part SS formed on the left and right (or upper and lower) areas of the second substrate 22 in the embodiment of FIG. 2A. However, in the upper and lower areas, the seating part SS is formed It can be. Generally, in the case where the display is of a horizontally elongated shape, a signal transfer film 33 for applying a gate signal and / or a power source is formed in left and right regions. Further, a signal transfer film 33 for applying a data signal and / or a power source is formed in the upper and lower regions. At this time, if the seating part SS is required in the upper and lower areas of the second substrate 22, the seating part SS can be formed at appropriate positions on the upper and lower sides of the second substrate 22.

Referring to FIG. 2B, an OLED display according to an embodiment of the present invention will be described. 2B is a view schematically showing a cross section taken along line B-B 'of 2a. At this time, the signal transmission film 33 is connected in a reverse bonding manner on the first substrate 11. The reverse bonding type means bonding in reverse to the conventional bonding method. In other words, conventionally, when one end of the signal transfer film 33 is connected to the first substrate 11, the other end of the signal transfer film 33 is placed outside the first substrate 11, ) And the like. The signal transfer film 33 and the printed circuit board PB are formed so as to be seated in the first substrate 11 by bending the signal transfer film 33 to be bent into the first substrate 11. In this case, there is a disadvantage in that the signal transmitting film 33 has to be bent, and there is inevitably a portion protruding to the outer periphery of the first substrate 11. In order to overcome this disadvantage, the signal transmission film 33 can be connected to the first substrate 11 by a reverse bonding method.

The signal transfer film 33 of the organic light emitting display according to the embodiment of the present invention is formed to be directed to the inside of the first substrate 11, but a bent region may be generated. That is, since the adhesive layer AD and the second substrate 22 are formed on the first substrate 11, there is a step difference from the upper surface of the first substrate 11 on which the signal transmission pad is formed. Therefore, a part of the signal transmission film 33 is bent. However, in the OLED display according to the embodiment of the present invention, since the seating part SS is formed on the second substrate 22, (33) may be less stepped than in the prior art.

The seating part SS is formed on at least one end of the upper portion or the lower portion of the second substrate 22 of the organic light emitting diode display according to the embodiment of the present invention. At this time, the seating portion SS may be formed to be smaller than the thickness of the central region of the second substrate 22. That is, the thickness of the central region of the second substrate 22 and the seating portion SS of the second substrate 22 may be stepped. One end of the signal transmission film 33 is connected to a signal transmission pad (not shown) formed on the first substrate 11 and the other end of the signal transmission film 33 is formed on the second substrate 22 It can be positioned on the seat portion SS.

The signal transmission film 33 of the organic light emitting diode display according to the embodiment of the present invention will be described with reference to FIG. At least one driver IC (DC) may be formed on the signal transfer film 33. The driver IC (DC) serves to supply necessary power to the panel or to transmit signals for displaying an image on the panel. However, the signal transmission film 33 of the organic light emitting display according to the embodiment of the present invention does not necessarily include the driver IC (DC). Sometimes a signal transfer film 33 that does not require a driver IC (DC) may be formed, and therefore it is not necessary to include a driver IC (DC).

At this time, the signal transfer film 33 may serve to transfer power required for driving the panel of the organic light emitting display device from a power supply unit (not shown), or to provide a path for transmitting power. In addition, it may serve to transmit a gate signal to reproduce an image. Of course, it may also transmit or apply a data signal for image reproduction. It may also serve to convey the necessary voltages or signals to other panels, but is not limited thereto. The signal transmission film 33 of the OLED display according to the embodiment of the present invention may be formed in the form of COF (Chip On Film) or TCP (Tape Carrier Package).

2A, a seating part SS serving as a guide can be formed on the second substrate 22 so that the signal transmitting film 33 can be seated at an appropriate position. At this time, the seating part SS formed on the second substrate 22 may accommodate at least a part of the signal transfer film 33 so that the other end of the signal transfer film 33 can be fixed. In addition, although the seating part SS may be formed exactly in conformity with the size of the signal transfer film 33, it may be formed slightly larger than the size of the signal transfer film 33 so that a slight gap may be generated.

In addition, the size and shape of the seating part SS can be formed in consideration of design and process margins. In particular, the design and process margins of the signal transfer film 33 should be considered. That is, there may be process errors different from the actually required specifications of the signal transmitting film 33. Also, consideration should be given to the design and process margins of the seated part (SS) itself. This is because the design size of the seat part SS and the actual size of the seat part SS may differ from each other in terms of process errors. It is also necessary to consider alignment margins that may occur when the signal transfer film 33 is connected to the first substrate 11 or placed on the seating portion SS.

Referring to FIG. 2B, a signal transmission pad is formed on the first substrate 11 on the periphery of the display region or on the non-display region. At least one end of the signal transmission pad is electrically connected to the signal transmission film 33. At this time, one end of the signal transfer film 33 is electrically connected to the first substrate 11, but the other end may not be connected. That is, when one end of the signal transfer film 33 is electrically connected to the first substrate 11, and only one end portion thereof is utilized as a signal transfer portion and an input / output portion of a power supply, none. The signal transmission film 33 may be connected to the first substrate 11 and the other end may be connected to the printed circuit board PB. However, as in the embodiment of the present invention, The other end of the signal transfer film 33 may not need to be connected to another printed circuit board PB or other part.

Referring to FIG. 2B, an adhesive layer AD may be formed for attaching the first substrate 11 and the second substrate 22 together. The adhesive layer AD may be formed to be equal to or slightly smaller than the size of the second substrate 22 so that the first substrate 11 and the second substrate 22 may be bonded together. Further, since the organic light emitting layer formed on the first substrate 11 may be vulnerable to moisture or oxygen, the adhesive layer AD functions to block moisture or oxygen that may occur outside or inside the organic light emitting display device .

Referring to FIG. 2C, an organic light emitting display according to an embodiment of the present invention will be described. 2C is a schematic view showing a section C-C 'of 2a. Particularly, FIG. 2C shows in cross section that at least a part of the signal transmitting film 33 is located on the seating part SS formed on the second substrate 22. In FIG. At this time, the signal transmission film 33 may be in direct contact with the lower surface or the upper surface of the seating portion SS, but may be positioned apart at a proper distance.

3A, an organic light emitting display according to an embodiment of the present invention will be described. FIG. 3A schematically shows a partial cross-section of a portion of the second substrate 22 on which the seating portion SS is formed. At this time, the lower surface (or the upper surface) in the inner space of the seating part SS may be formed to be parallel to the upper surface or lower surface of the second substrate 22. As described above, the seating part SS may be formed at at least one end of the second substrate 22, and may have a thickness smaller than the central area of the second substrate 22.

Referring to FIG. 3B, an organic light emitting display according to an embodiment of the present invention will be described. FIG. 3A schematically shows a partial cross-section of a portion of the second substrate 22 on which the seating portion SS is formed. At this time, at least a part of the lower surface or the upper surface in the inner space of the seating part SS may be formed so as not to be parallel to the upper surface or the lower surface of the second substrate 22. That is, at least a part of the upper surface of the seating part SS located at a position close to one end of the signal transfer film 33 connected to the first substrate 11 is inclined, Can be stably positioned at the seat portion SS. Hereinafter, the same features as those described above will be omitted.

Referring to FIG. 4A, there is schematically shown another cross section of a seating part SS formed on a second substrate 22 of an OLED display according to an embodiment of the present invention. At this time, the seating part SS can form the shape of the seating part SS differently from the shape of the seating part SS described above so that the signal transmitting film 33 can be stably mounted. That is, the signal transfer film 33 may further include a driver IC (DC) on the signal transfer film 33, and the signal transfer film 33 may include a driver IC (DC) The inner cross section may be formed such that its diameter is not constant. That is, when the driver IC (DC) is formed on the signal transfer film 33, the shape of the seating part SS may be formed so as to be similar to the overall shape of the signal transfer film 33. Referring to the cross section of the seating part SS shown in FIG. 4A, the width of the upper space and the lower space of the seating part SS can be formed differently. That is, the driver IC (DC) formed on the upper portion of the signal transfer film 33 is positioned above the seat portion SS and the width thereof is formed as D1. Further, the signal transmission film 33 is positioned below the seating part SS, and its width is D2. At this time, since the width of the driver IC (DC) is smaller than the width of the signal transfer film 33 itself, the length of D1 may be shorter than D2.

Referring to FIG. 4B, there is schematically shown another cross section of a seating part SS formed on a second substrate 22 of an OLED display according to an embodiment of the present invention. At this time, the bottom surface of the seating part SS may have at least a bottom surface having a stepped shape with a step in the lower space. By doing so, it becomes possible to secure a heat releasable space that can be generated in the signal transmission film 33.

Referring to FIG. 4C, another cross section of a seating part SS formed on a second substrate 22 of an OLED display according to an embodiment of the present invention is schematically shown. At this time, the inner cross section of the seat portion SS may be formed in a closed shape except for the entrance where the signal transmission film 33 enters. That is, the seating part SS can be formed in the form of a hole in the upper surface or the lower surface of the second substrate 22. Alternatively, the seating part SS may be formed in the form of a side surface of the second substrate 22. In the case of forming the seating part SS in the form of a side groove, interference between each other can be minimized since there is no direct contact between the signal transmitting film 33 and other parts to be formed on the second substrate 22.

Referring to FIG. 4D, another cross-sectional view of the seating part SS formed on the second substrate 22 of the OLED display according to the embodiment of the present invention shown in FIG. 4C is schematically shown. That is, the cross section of the seat SS is formed so as to resemble the shape of the signal transfer film 33 on which the driver IC (DC) is formed, so that the signal transfer film 33 is positioned more stably on the seat SS .

Referring to FIG. 4E, a cross section of a seating part SS formed on a second substrate 22 of an OLED display according to an embodiment of the present invention is schematically shown. The first substrate 11 may further include an adhesive layer AD formed between the first substrate 11 and the second substrate 22. The second substrate 22 may have a seating portion SS closer to the contact layer / RTI > That is, if the space of the seating part SS formed on the second substrate 22 is formed in a region close to the adhesive layer AD, as in the embodiment of the present invention described with reference to FIG. 4C or 4D, It is possible to minimize the interference between the signal transmitting film 33 and other parts to be formed on the second substrate 22 without forming the seating part SS having a groove shape. That is, since the lower surface of the seating part SS is positioned between the signal transfer film 33 and other parts to be formed on the second substrate 22, there is no direct physical contact with each other.

Referring to FIG. 5, the seating part SS formed on the second substrate 22 of the organic light emitting diode display according to the embodiment of the present invention will be described with reference to FIG. 5. In the upper and lower and left and right end regions of the second substrate 22, And shows the formed seating part SS.
