Description

Organic light emitting display device and manufacturing method thereof

The present invention relates to a display device and a manufacturing method thereof.

With the development of electronic technology, various display technologies for displaying visual information as images are being developed. As one of these display technologies, many electroluminescent displays are used.

An electroluminescent display refers to a technology for displaying an image using a light emitting device that generates light by recombination of electrons and holes. The electroluminescent display may be implemented as an organic light emitting display (OLED), a quantum dot display, a micro light emitting diode (μ-LED) display device, and the like.

Among them, the organic light emitting display device uses a light emitting element that emits light, so it is possible to express a low gray scale, provides a fast response speed, and can be implemented flexibly. .

However, since organic compounds are used in such an organic light emitting display, when used for heat and long-term screen exposure, there is a problem in that the lifetime of the organic compound is adversely affected, that is, burn-in occurs.

In particular, when such organic light emitting displays are used in industrial fields such as public displays that must be used outdoors or slot machine game machines that require sharper and higher brightness, there is a problem in that burn-in is more easily induced and durability is lowered. .

An organic light emitting display device 100 according to an embodiment of the present invention disclosed below is a display used in an industrial field, for example, a public display used outdoors or a field requiring high luminance such as a slot machine game machine. used in

Accordingly, a reflection blocking layer that blocks reflection by an external light source is required, but in the organic light emitting display device 100 according to an embodiment of the present invention, such a reflection blocking layer is not included in the organic light emitting display panel, and the glass module form it This is because the brightness of the organic light emitting display panel decreases when the reflection blocking layer is formed on the organic light emitting display panel, and thus the driving current applied to the organic light emitting display panel increases. Therefore, the organic light emitting display panel of the organic light emitting display device 100 according to an embodiment of the present invention does not include the antireflection layer, but also lowers the driving current for driving the organic light emitting display panel below the standard range, so that organic light emitting A current load of the display panel may be reduced, thereby preventing burn-in of the organic light emitting display panel.

This will be described in more detail below with reference to FIGS. 1 to 5 .

1 is a perspective view illustrating an example of an organic light emitting display device according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of an example of the organic light emitting display device illustrated in FIG. 1 .

Referring to FIGS. 1 and 2 , the organic light emitting display device 100 may include a glass module 110 , an organic light emitting display panel 130 and a back cover 150 .

A glass module 110 is provided on the front of the organic light emitting display device 100 . The glass module 110 includes tempered glass and can provide durability and stability required in an industrial display use environment.

The glass module 110 may be positioned on the front surface of the organic light emitting display panel 130 and may include a reflection blocking layer blocking reflection by an external light source.

In one embodiment, a touch sensor may be attached to the glass module 110 to provide a touch function. A touch sensor may be attached to an inner surface of the glass module 110, that is, one surface of the back cover 150 to provide a touch function.

In one embodiment, the touch sensor included in the glass module 110 may provide a reflection blocking function to block reflection by the external light source. For example, the touch sensor is formed using a unidirectional light absorbing film as a substrate, so that light from an external light source can be blocked while light generated from an internal display module can be transmitted.

In one embodiment, the glass module 110 may include a polarizing film and a touch sensor, and may prevent reflection of light by an external light source through the polarizing film and the touch sensor.

The organic light emitting display panel 130 displays an image based on organic light emitting diodes emitting light with brightness corresponding to the magnitude of a driving current. The organic light emitting display panel 130 does not include an optical film for blocking reflection by an external light source.

For example, the organic light emitting display panel 130 includes a polarizing film for blocking reflection, but the optical film for blocking reflection is removed through a separate process and may not include the optical film for blocking reflection.

As another example, the organic light emitting display panel 130 may be produced without a polarizing film for blocking reflection in the manufacturing process.

The back cover 150 constitutes a rear portion of the organic light emitting display device 100 and contains the organic light emitting display panel 130 therein. Although not shown, in the space between the glass module 110 and the back cover 150, not only the organic light emitting display panel 130 but also the organic light emitting display panel 130 and other elements (eg, a touch sensor) are driven. A circuit structure or the like to do so may be fixed.

FIG. 3 is a diagram illustrating an example of an organic light emitting display device according to an embodiment of the present invention, and the organic light emitting display device 100 will be described with reference to FIG. 3 .

Referring to FIG. 3 , the organic light emitting display device 100 includes a glass module 110 including a touch module, an organic light emitting display panel 130 , a touch controller 120 and a display controller 140 .

The glass module 110 may include a touch sensor TM. Various conductive films may be used as the touch sensor TM, and the type of the touch sensor TM is not limited to a specific type in the present invention. For example, a transparent conductive layer such as indium tin oxide (ITO) may be used. As another example, a metal conductive film having opacity in some regions, such as a metal mesh, may be used.

The touch controller 120 may calculate the occurrence of a touch event and the touch location using the touch sensor TM. The touch controller 120 may provide detected touch information, eg, touch event generation information and touch location information to an industrial device, eg, a game machine.

The display controller 140 controls the operation of the organic light emitting display panel 130 .

The display controller 140 may control image display of the organic light emitting display by applying a driving current to the organic light emitting display panel 130 .

In one embodiment, the display controller 140 may lower the driving current range of the organic light emitting display panel from the standard range. For example, the display controller 140 may lower the output range of the driving current so that the driving current is output 30% to 50% lower than the standard range of the driving current range for the organic light emitting display panel. This is because the organic light emitting display panel does not include an optical film for blocking reflection, so that the brightness of the organic light emitting display panel is not reduced even when the output range of the driving current is lowered. In this way, by setting the output range of the driving current of the organic light emitting display panel downward, it is possible to prevent burn-in of the organic light emitting device and improve the lifespan.

In one embodiment of the present invention, an anti-reflection layer is formed on the glass module. Hereinafter, exemplary embodiments of the glass module will be described with reference to FIGS. 4 and 5 .

Referring to FIG. 4 , the glass module 110 may include a tempered glass 111 , a polarizing film 112 , and a touch sensor 113 .

The tempered glass 111 is formed on the front surface of the organic light emitting display device 100, and the polarizing film 112 is attached to the inner surface of the tempered glass.

The polarizing film 112 performs polarization by passing light from an external light source input through the tempered glass in only one direction.

One surface of the polarizing film 112 may be attached to an inner surface of the tempered glass 111 , and the touch sensor 113 may be attached to the other surface of the polarizing film 110 .

The touch sensor 113 delays the phase of light passing through the polarizing film, and through this, the light passing through the touch sensor 113 may be blocked by the polarizing film 112 due to the phase delay.

FIG. 5 is a diagram illustrating a process of blocking reflection by an external light source by a glass module according to an embodiment of the present invention. This process of blocking reflection will be described with further reference to FIG. 5 .

Referring to FIG. 5 , a polarizing film 112 , a touch sensor 113 and an organic light emitting display panel 130 are shown.

The polarizing film 112 and the touch sensor 113 are provided on the glass module 110, and the organic light emitting display panel 130 is positioned on the rear surface of the glass module.

When light generated from an external light source passes through the polarizing film 112, only light in one direction is transmitted through the polarizing film. That is, in the illustrated example, only vertical light passes through the polarizing film 112 .

The touch sensor 113 may provide a phase delay function.

For example, since the electrode patterns are continuously arranged in the touch sensor 113, a partial phase change occurs by itself due to the continuous arrangement of the electrode patterns. Accordingly, a phase retardation occurs by the touch sensor 113 without using a separate phase retardation film.

As another example, a phase retardation film may be used as a base film of the touch sensor 113, and a sensor electrode may be formed on the base film. For example, the touch sensor 113 may be a phase retardation film (Quarter Wave Plate) that delays 1/4 of a wavelength. This example is applicable when it is desired to ensure a more reliable phase delay.

Light passing through the polarization film 112 is phase delayed while passing through the touch sensor 113 , and the phase delayed light is reflected by the organic light emitting display panel 130 . The phase of the reflected light is delayed while passing through the touch sensor 113 again. Accordingly, since the light that has passed through the touch sensor 113 again has a different phase from the light that initially passed through the polarizing film 112 , it does not pass through the polarizing film 112 and is blocked.

As described above, even if light from an external light source is reflected by the organic light emitting display panel 130 , the reflection blocking function is performed as described above, so that the reflection from the external light source is not displayed to the user. Accordingly, convenient visibility can be provided to the user.

In FIGS. 4 to 5, an example using a touch sensor as a polarizing film and a retardation film has been described, but is not limited thereto.

As another example, the touch sensor itself may provide a reflection blocking function to block reflection by an external light source.

The organic light emitting display device described above with reference to FIGS. 1 to 5 has been described by exemplifying a flat-panel display device, but is not limited thereto. For example, the organic light emitting display device may be a curved display device as illustrated in FIG. 11 .

This is because the organic light emitting display panel 130 has flexibility and can be fixed in a curved shape. In addition, a curved glass module may be formed by mounting the tempered glass on a curved frame and exposing it to a high temperature, and by laminating curved films on the curved tempered glass. To this end, the back cover may have a configuration for fixing the organic light emitting display panel in a curved shape, for example, a slide, a fastening frame, a fastening bolt structure, and the like. In addition, it may have a structure that is not fixed to the curved glass module from the front, for example, a slide structure, a fastening frame, an adhesive structure, and the like.

In the above, the organic light emitting display device according to an exemplary embodiment of the present invention has been described. Hereinafter, a method of manufacturing an organic light emitting display device according to an exemplary embodiment of the present invention will be described with reference to FIGS. 6 to 10 .

Referring to FIG. 6 , in order to manufacture an organic light emitting display device, an organic light emitting display panel is prepared (S610). 7 shows an example of such an organic light emitting display panel. Here, the organic light emitting display panel is a panel that emits light with brightness corresponding to the magnitude of the driving current, as described above.

A step of removing the optical film from the prepared organic light emitting display panel may be performed (S620). 8 illustrates an example of removing an optical film from a prepared organic light emitting display panel. Here, the removal of the optical film may be performed in various ways, such as being performed through a film peeling device or performed by a worker.

A glass module may be created by forming a reflection blocking layer on the tempered glass to block reflection by an external light source (S630). FIG. 9 illustrates an example of forming an anti-reflection layer by laminating the reinforced glass as an example of S630.

In one embodiment, in order to form the antireflection layer, a polarizing film may be attached to an inner surface of the tempered glass, and a touch sensor may be attached on the attached polarizing film. Here, it is as described above that the touch sensor provides an effect of delaying the phase of light passing through the polarizing film.

In another embodiment, a touch sensor may be attached to the inner surface of the tempered glass to form the antireflection layer. In this case, the touch sensor itself may provide a reflection blocking function to block reflection by an external light source. To this end, the touch sensor is formed using a unidirectional light absorbing film as a base material to block light from an external light source and transmit light generated from an internal display module.

Thereafter, the organic light emitting display panel from which the polarizing film is removed may be fixed to the back cover, and the tempered glass having the reflection blocking layer formed thereon may be fixed in front of the organic light emitting display panel (S640).

Therefore, the tempered glass may be fixed to the front portion of the back cover, and the organic light emitting display panel may be mounted in a space between the tempered glass and the back cover.

In addition, the driving current range for the organic light emitting display panel may be set lower than the standard range (S650).

In the above, an example of a method for manufacturing an organic light emitting display device has been described with reference to FIGS. 6 to 9 .

Referring to FIG. 10 , in order to manufacture an organic light emitting display device, an organic light emitting display panel is prepared (S1010).

Thereafter, a step of removing the optical film from the prepared organic light emitting display panel may be performed (S1020).

In order to create a curved glass module, a curved tempered glass may be prepared (S1030).

For example, when the organic light emitting display panel is fixed to the back cover, it may be fixed to have a predetermined curvature, and the tempered glass may be curved to have a curvature corresponding to the curvature of the organic light emitting display panel.

Thereafter, a step of forming a curved tempered glass module may be performed by laminating a reflection blocking layer on the curved tempered glass to the curved surface (S1040).

In addition, the organic light emitting display panel may be fixed to the back cover to have a predetermined curvature (S1050), and a step of fixing the curved tempered glass module to the corresponding back cover may be performed (S1060).
