1 is a diagram showing an exemplary configuration of a display device as an example of a product to which the present invention can be applied.

An alignment part 55 for aligning the camera and the display device is disposed in some areas of the display device, and an opening 53 inside which the camera lens is aligned is disposed. The display device 10 outputs image data provided from the outside to the outside using various light sources. In this process, image data is displayed on the display panel 100 by emitting red light (R), green light (G), and blue light (B), and can optionally emit white light (W).

In the display panel 100 that displays an image on the display device 10, the camera 5 may be disposed in a non-display area where the image is not displayed, that is, the peripheral area 100n. To this end, one or more coupling parts for lens alignment are disposed in the peripheral area 100n, which is a non-display area of the display panel, and the display device 10 inserts a camera lens or an alignment pin placed on the camera into these coupling parts. Contains one or more cameras that The coupling portion may be configured in the form of an opening or groove. In one embodiment, one or more coupling portions, for example, openings or grooves, for lens alignment are disposed on the display panel of the display device, and the one or plurality of coupling portions include lenses or aligners of one or more cameras. The in pin is inserted. Accordingly, components protruding from the camera may be inserted and aligned within the coupling portion, and some components of the camera may be fastened to the coupling portion. Figure 1 shows an example in which one camera is placed, and Figure 8 shows an example in which multiple cameras are placed.

In order for a camera placed in the peripheral area of the display panel to easily receive light containing an external image, it is advantageous not to place pixels and a circuit structure for driving them in the area of the display panel where the camera lens is placed.

In this situation, in order to maximize the display area of the display panel where the camera is placed, it is necessary to devise a fastening structure to minimize the opening area on the display panel for light to enter the camera lens. Accordingly, this specification presents a structure that implements a coupling part for arranging a camera lens disposed on a display panel with the minimum size or number.

An alignment pin, which is a separate structure, may be formed on the upper part of the camera for precise alignment with the opening or groove of the display panel. The opening refers to a structure that is completely open, and the groove refers to a structure in which part of the display panel is dug out and the remaining portion is blocked. All openings or grooves are collectively referred to as joints. The camera can be fastened so that the lens area of the camera is precisely aligned with the opening where the lens of the display panel is disposed, using an alignment pin (alignment structure) inserted into a coupling portion of a display panel that displays an image.

Let's look at detailed fastening structures in the embodiments of FIGS. 2 to 11. Additionally, a camera lens may be inserted or placed in the coupling portions 160a, 160b, and AM. In one embodiment, an alignment pin for aligning the camera and the display panel may be formed on the upper part of the camera barrel including the camera alignment portion 55 and the external case 57, and the alignment pin of this camera barrel may be displayed as a display panel. It may be arranged in such a way that it is inserted into a coupling part formed in the form of a groove or an opening of the panel. This will be discussed in Figures 12 and 13.

FIG. 2 is an enlarged view of the 100n area of FIG. 1 and is a front view of a camera on which an alignment pin described in an embodiment of the present invention is disposed. 20a is a view showing the camera 5 structure from the front, and 20b is a view showing the camera 5 structure arranged below the display panel 100. In one embodiment, two alignment pins 60a and 60b are arranged at symmetrical positions based on the lens 51 of the camera.

Correspondingly, two alignment grooves in the display panel where two alignment pins 60a and 60b are coupled may be disposed at symmetrical positions with respect to the lens. In one example, the two coupling parts indicated by AM in FIG. 5 were arranged symmetrically.

The uppermost lens 51 of the camera and an opening 53 corresponding to the maximum angle area through which light can sufficiently enter the lens 51 are shown. Additionally, alignment pins 60a and 60b are disposed around the lens for alignment when fastened to the display panel 100. One or more alignment pins 60a and 60b may be placed on the camera 5. Additionally, the camera 5 includes an alignment portion 55 surrounding the lens of the camera and an external case 57.

The alignment pins 60a and 60b are used to accurately connect the lens 51 and the display panel 100. Depending on the fastening method and the type of alignment pin, there may be one or more. Alternatively, when two or more cameras are placed, alignment pins may be placed only on some of the cameras.

20b shows a structure in which the camera 20a is placed at the bottom of the display panel 100. The display panel 100 includes coupling portions 160a and 160b in the form of alignment grooves into which the alignment pins 60a and 60b can be fastened. The coupling portions 160a and 160b are arranged in a non-display area. Additionally, the opening 151 corresponding to the lens is also disposed in the non-display area.

The coupling portions or openings of 160a, 160b, and 151 may be formed on the substrate of an organic light emitting display panel (OLED), and the coupling portions or openings may not exist in the cover glass thereon. The detailed structure of the camera and the connection points of the alignment pins are examined in Figure 5.

To examine in more detail the fastening structures of the camera 5 and the display panel 100, the cross section K-K' and the cross section L-L' are examined.

Figure 3 is a diagram showing a cross section of a camera and a display panel connected according to an embodiment of the present invention. Figure 2 shows the K-K' cross section.

3 shows the display panel 100 in more detail. In the structure of FIG. 3, the display panel 100 is an organic light emitting display panel as an example. A/A indicates the display area where the image is displayed. The display panel 100 in FIG. 3 uses POLED (Plastic OLED) as an example. POLED refers to OLED that uses a flexible plastic substrate. POLED is a process of placing TFT and OLED on a plastic substrate. In one embodiment, a PI (poly-imide) solution is coated on a glass substrate, cured, and the coated PI solution is turned into a film. do. In Figure 3, you can see the difference in the area of the non-display area between the case where the alignment pin is applied (21a) and the case where the alignment pin is not applied (21b).

In FIG. 3, 111 represents an OLED substrate as an example. 112 is a polarizer, and 113 is a light blocking layer, and may be patterned and disposed on the back of the cover glass. And 90 coupled to the display panel 100 indicates the cover glass. A case 80 may be placed on the side of the display panel 100. The case 80 protects the back or side of the display panel 100 and may also provide a function of fixing the cameras. However, the present invention is not limited to the case 80.

Looking at the detailed configuration of the camera 5 according to the application of the present invention, 21a in Figure 3 shows the arrangement of the first lens 51a, the second lens 51b, the third lens 51c, and the fourth lens 51d. do. The number of lenses can be increased or decreased depending on the configuration of the camera 5, and a component 52 for image capturing is disposed under the lowest lens, which is an example of a CMOS image sensor.

And opening areas, including a portion corresponding to the opening 53 of the alignment unit 55, are disposed in areas 111, 112, and 113 of the display panel 100. That is, an OLED substrate in which the open areas of the alignment portion 55 in the layers 111, 112, and 113 of the display panel 100 are each component of the display panel 100, that is, the opening areas are arranged in a line in the opening 53. (111), the polarizing part 112, and the light blocking layer 113. The opening area refers to an open area through which light can pass through the substrate (eg, PI film), polarization part, light blocking layer, etc. In the configuration of FIG. 3, the polarizing portion 112 may be selectively removed or disposed.

21a in FIG. 3 corresponds to the opening 53 and has a mechanical tolerance (A), a poly-imide (PI) margin (B), an encap margin (C), and a camera hole margin (D) as manufacturing tolerances and margins. These margins mean a wider opening in case the opening area does not exactly match the lens, or a margin that occurs due to mechanical tolerance (A). Each component has a specific margin, and when components accumulate, the size of the margin can increase. When a camera is fastened to a display panel based on this structure, the loss of the display area at the camera fastening portion of the display panel corresponds to the lens diameter (R1) and the manufacturing tolerances and margins described above. For example, the loss of the display area may correspond to the area of a circle with a diameter of R1+2*(B+C+D).

Meanwhile, 21b is a configuration without an alignment pin, and shows that it is formed as a coupling portion on the OLED substrate 111 of the display panel equal to the size of the alignment portion 55 constituting the lens barrel. As a result, it can be seen that the size of the open areas 112, 113, etc. of the display panel 100 increases compared to 21a. That is, the open area of 21a has a size (R1) corresponding to the size of the lens. On the other hand, the open area of 21b has a size (R2) corresponding to the size of the alignment portion 55 constituting the barrel. It can be confirmed that in the structure of 21b, which cannot accurately align the lens and the display panel 100, a larger area is opened in the OLED substrate 111 beyond the size of the lens, which means an increase in the non-display area. . That is, in the case of a structure without an alignment pin, the upper part of the alignment unit 55 may be coupled to the OLED substrate 111 in order to accurately align the lens to the opening area of the OLED substrate 111. When a camera is fastened to a display panel based on this structure, the loss of the display area at the camera fastening portion of the display panel includes the diameter R2 of the alignment portion 55 constituting the lens barrel with a lens diameter R1 or more, and R2+2* It corresponds to the area of a circle with a diameter of (A+B+C). Here, as can be seen in FIG. 3 21b, the size R2 of the opening area at 21b of the OLED substrate 111 of FIG. 3 is always larger than the size R1+2*D of the opening area of 21a of the OLED substrate 111 of FIG. 3. It has length. R1 has a smaller value than R2, and R2 includes the camera hole margin (D). Therefore, in the case of the configuration with the alignment pin proposed in the present invention, the loss of the display area is always less than the configuration without the alignment pin.

As a result, it can be confirmed that the sizes of the display areas (Active Area, AA) of the display panel 100 are also different between 21a and 21b. This is because 21a has a separate alignment pin, so the open area corresponding to the lens size can be formed as a coupling portion.

That is, in the case of the existing fastening structure, the outer corner of the camera alignment part 55 is accurately aligned with the opening area of the display panel 100 as shown in 21b to align the set module including the camera, display panel, and case 80. Therefore, various tolerances are accumulated, and the reduction in the light emitting area of the display panel is very large. This can be confirmed by comparing the sizes of the open areas of the OLED panel 111.

On the other hand, the fastening structure 21a in which the alignment pin is combined according to the embodiment of the present invention uses the alignment pins 60a and 60b of the camera alignment unit 55 to connect the lens of the camera and the display panel 100. It can be adjusted to align the opening area. Based on this, the required tolerances during production can be reduced and the light emitting area of the display panel can be maximized. Let’s look at this in more detail.

Figure 4 is a diagram showing a case where a camera according to another embodiment of the present invention is placed in close contact with the case 80. As seen in Figure 2 or Figure 3, the camera is in close contact with the case 80.

As shown, the case 80 fixes the display panel 100 and other components. When a camera is placed closely to the case 80, the display area occupied by the display panel 100 may be placed on one side without being divided. Accordingly, the position between the position of the camera 5 and the display panel 100 can be selected according to the characteristics of the display device 10 to be implemented.

3 and 4, an opening for lens alignment is disposed on one side of the display area of the display panel and in a non-display area where no image is displayed.

FIG. 5 is a diagram showing a cross section taken along line L-L' of FIG. 2 according to an embodiment of the present invention. As seen above, when combined with the display panel 110, the camera 5 may include a separate align pin to match the position of the lens with the opening area of the display panel 110 to expand the display area. there is.

The configuration of the camera 5 in FIG. 5 is the same as previously discussed. Alignment pins 60a and 60b are placed on the top of the camera.

Alignment pins can be one or multiple. If the alignment pin is arranged long in a specific direction or can be fixedly connected in a cross shape, one alignment pin may be disposed when coupled to the display panel 100 without tolerance. Alternatively, two alignment pins may be placed on the camera 5 to increase the strength of the coupling.

Alternatively, when more than one camera is coupled to the display panel 100, one alignment pin may be placed on each of the two cameras and these cameras may be connected as one unit.

In FIG. 5 , when the display panel 100 is an organic light emitting display panel, alignment pins 60a and 60b are disposed at the upper part of the camera 5. Additionally, the organic light emitting display panel includes an engaging portion (AM) where the camera's alignment pin is placed and an opening (RC) where the camera lens is placed.

In FIG. 5 , the coupling portion disposed on the display panel 100 is opened in the same shape as the alignment pin disposed on the camera. This means that the coupling portion is arranged in an open shape in the opening area so that the alignment pin can be inserted. For example, if the alignment pin is square, the shape of the coupling portion is also square.

Corresponding to the cross-shaped alignment pin as shown in FIG. 6, which will be described later, the shape of the coupling part of the display panel is also cross-shaped, forming a groove or opening. In response to the bent alignment pin as shown in FIG. 7, which will be described later, the shape of the coupling portion of the display panel also becomes bent.

Figure 6 is a diagram illustrating a case where one alignment pin according to an embodiment of the present invention is arranged in a cross shape. For convenience of explanation, only the upper part of the camera unit is shown. It can be compared with Figure 2.

The alignment pin 60c is configured in a cross shape, thereby increasing the coupling force between the camera unit 5 and the display panel 100.

Figure 7 is a diagram showing the configuration of an alignment pin in a bent shape according to an embodiment of the present invention. The alignment pin 60d has a bent shape to surround the opening of the lens, thereby increasing the coupling force between the camera unit 5 and the display panel 100.

When applying a complex alignment pin shape, it may be placed only on one side of the lens. Alternatively, if a simple alignment pin is used, it can be placed on both sides of the lens.

As shown in Figure 2 or Figure 6, where the alignment pin is placed on the top of the camera or in what form can be selected in various ways depending on the number of cameras, characteristics of the cameras, size of the alignment pin, etc. The present invention is not limited to this.

Figure 8 is a diagram showing the configuration of a compound camera according to an embodiment of the present invention. This has the effect of reducing the size of the camera to expand the display area of the display panel.

Additionally, two or more cameras can be placed on the display device to increase the amount of light received while reducing the size of the camera and correspondingly reducing the size of the lens. Figure 8 is a diagram showing a configuration in which a complex camera including six cameras is arranged in a display device.

The boundary between the non-display area (100n) and the active area in FIG. 1 is enlarged as shown in FIG. 8. Although only one camera 5 is disposed in FIG. 1, six cameras (5a, 5b, 5c, 5d, 5e, 5f) are disposed in FIG. 8, and they operate as composite cameras.

When using a composite camera consisting of two or more cameras, the size of the individual cameras is reduced compared to using a single camera. As a result, the size of the opening area placed on the display panel where the camera is combined to receive light is also reduced for one camera, and as a result, the size of the distance indicated by dist is reduced. For example, in the case of OLED, it can be reduced to 2.3mm or less. In the case of LCD, it can be reduced to 3mm or less. This increases the size of the display area within the display panel.

Additionally, when connecting multiple cameras, the align pin may be placed on individual cameras or only on some cameras.

Figure 9 is a diagram showing an alignment pin disposed in a complex camera according to an embodiment of the present invention. In the configuration of FIG. 8, for convenience, only the portion where the composite camera 205 consists of three individual cameras (unit cameras) 5a, 5b, and 5c is shown.

22a is a configuration in which alignment pins 260a, 260b, ..., 260f are placed on each individual camera. 22b is a configuration in which alignment pins 260a and 260f are placed on only some of the individual cameras. When individual cameras are coupled to each other, alignment pins can only be placed on some cameras. Even if alignment pins are placed only on some cameras, the entire composite camera can be aligned because the individual cameras are connected to each other.

When a complex camera is applied as shown in FIG. 9, the effect of reducing the size of the non-display area (100n) shown in FIG. 1 increases. For example, when multiple cameras are deployed, each camera receives light, so the aperture area for the lens of an individual camera is smaller than the aperture area when only one camera is used. That is, in an embodiment of a composite camera in which the lens size is reduced and a plurality of open areas are arranged, the size of the open area corresponding to each camera is reduced, thereby increasing the size of the display area of the display panel 100. Figure 10 is a diagram showing a cross section when a complex camera according to an embodiment of the present invention is arranged. When an organic light emitting display panel is configured as shown in FIG. 8 as an example, the N-N' cross section is examined. The alignment pin of the composite camera is based on an embodiment configured as shown at 22a in FIG. 9.

The display panel 100 includes an opening RC for a lens and an engaging portion AM into which the alignment pins 260c, 260d, 260e, and 260f are fastened or inserted. The two cameras can be combined by a separate device, or the alignment part 55 that forms the camera barrel can be attached without any gaps. For example, two cameras can be placed fixed to a case. Additionally, the alignment pins are inserted into the coupling portion (AM) but may have a certain tolerance.

Figure 11 is a diagram showing a configuration in which a camera is disposed on the outer portion of an OLED display panel according to an embodiment of the present invention. Figure 11 is a diagram showing a structure in which the display area of the display panel ends and the coupling portion is disposed outside the area where the sealant is disposed. The sealing agent seals the area where the organic light emitting devices and the transistors that control their light emission have been placed, preventing air or moisture from permeating.

123 is an area where pixels are placed and the OLED layer, pixel electrodes, transistors, etc. are placed accordingly. Configure the display area. 122 is an area where the spacer 122s and the passivation layer 122p are disposed. And 121 is an area where various lines that provide signals to the active area are arranged.

According to one embodiment of the present invention, the sealant 130 is disposed from the middle area of 123 to the end of area 121. The coupling portion is disposed in an area of the display panel 100 where the sealant 130 is not disposed. In Figure 10, a single camera 5 is arranged, but as previously seen in Figure 9, multiple cameras may be arranged in a row.

However, since each camera of the composite camera is arranged at regular intervals as shown in FIG. 11 in relation to the display panel 100, the areas 121, 122, and 123, which are directly related to the ratio of the actual display area, are maintained. That is, the cross section MM' of FIG. 8 may also be configured as shown in FIG. 11. Of course, the cross section K-K' in FIG. 2 can also be configured as in FIG. 11.

The area where the circuit is placed by applying an alignment pin in the combination of the camera and the display panel and reducing the open area (or area consisting of grooves) that provides the function of the coupling part on the display panel by applying a composite camera. A camera can be placed on the outside of (121). As a result, the reliability of elements arranged in the display area of the display panel can be improved, and the size of the display area can be secured, thereby improving the quality of the output image.

Figure 12 is a diagram showing the configuration of a camera coupled to a liquid crystal display panel according to another embodiment of the present invention. In a configuration in which the upper glass (top glass) 310, lower glass (lower glass) 320, and backlight unit 330 of the liquid crystal display panel 300 are arranged, the camera 5 opens a portion of the lower glass. combined into one area.

In one embodiment, a part of the barrel including the lens of the camera 5 (for example, the alignment part 55) is inserted into the coupling part of the lower glass and coupled to the display panel 300. In this case, the camera 5 The entire upper part becomes an alignment pin.

In the case of a liquid crystal display panel, the upper glass 310 and lower glass 320 have thicknesses, so they can be combined with OLED in a different way. It can also be configured in such a way that the upper part of the camera becomes a kind of alignment pin and is coupled to the coupling part created by opening some areas of the display panel. And the coupling portion is disposed only on the lower glass of the display panel.

Additionally, the lens of the camera and the barrel surrounding it can be inserted into the coupling portion of the lower glass using an alignment pin.

Figure 13 is a cross-sectional view showing the configuration of a complex camera according to an embodiment of the present invention. When the liquid crystal display panel is configured as shown in FIG. 8 as an example, the N-N' cross section is examined. It can be confirmed that the alignment pin of the composite camera is the upper surface of each camera (5b, 5c).

The two cameras can be combined by a separate device, or the camera barrel can be configured to be attached without any gaps. For example, two cameras can be placed fixed to a case.

In the embodiments of FIGS. 10 and 13 , the display device may include two or more cameras. And according to this, the coupling portion for each camera can be arranged.

In the embodiment of FIG. 10, the first coupling portion for lens alignment of the first camera 5b and the second coupling portion for lens alignment of the second camera 5c are displayed as AM on the display panel 100.

Hereinafter, description will be made with reference to FIGS. 15 to 17.

FIG. 15 is a diagram showing a configuration in which a complex camera including five cameras is arranged in a display device. The number of cameras of a composite camera can be set in various ways. Hereinafter, overlapping descriptions will be omitted simply for convenience of explanation.

In Figure 15, five individual cameras (405a, 405b, 405c, 405d, 405e) are arranged, and they operate as composite cameras. Piezoelectric transducer elements (470aa, 470ab, 470ba, 470bb, 470ca) of the composite camera arranged adjacent to the alignment pins (460aa, 460ab, 460ba, 460bb, 460ca, 460cb, 460da, 460db, 460ea, 460eb) of the composite camera. , 470cb, 470da, 470db, 470ea, 470eb) are provided. Each piezoelectric transduction element is configured to receive a control signal. When a control signal is supplied to each of the piezoelectric transduction elements (470aa, 470ab, 470ba, 470bb, 470ca, 470cb, 470da, 470db, 470ea, 470eb) of the composite camera, the individual cameras (405a, 405b, 405c, 405d, 405e) of the composite camera ) You can tilt the camera's angle of view by independently controlling the angle. That is, the individual cameras (405a, 405b, 405c, 405d, 405e) are configured according to the control signals supplied to the piezoelectric conversion elements (470aa, 470ab, 470ba, 470bb, 470ca, 470cb, 470da, 470db, 470ea, 470eb). It has the effect of changing the field of vision.

Each individual camera is configured to include at least a piezoelectric transduction element corresponding to an alignment pin of the individual camera. For example, the first camera 405a includes a first align pin 460aa and a second align pin 460ab, and the first piezoelectric transducer 470aa and the second piezoelectric transducer 470ab are It is placed on the corresponding alignment pin. According to the above-described configuration, since the camera is fixed by an alignment pin, even if the camera's angle of view is tilted due to the operation of the piezoelectric transducer, the camera's angle of view can be adjusted precisely.

Referring to FIG. 16, an example is shown in which the field of view of the individual cameras 405a, 405b, 405c, 405d, and 405e can be individually adjusted to more effectively photograph the subject 1. The first camera 405a has a first angle of view 415a. The second camera 405b has a second angle of view 415b. The third camera 405c has a third angle of view 415c. The fourth camera 405d has a fourth angle of view 415d. The fifth camera 405e has a fifth angle of view 415e. According to the above-described configuration, when the composite camera takes a close-up shot, all the individual cameras 405a, 405b, 405c, 405d, and 405e have the effect of being able to photograph the subject (1). To elaborate, the angle of view adjustment of the third camera 405c or the camera disposed in the center of the composite camera can be minimized. And the farther away you are from the center, the greater the degree of angle of view adjustment can be. Therefore, there is an effect of making macro photography easier. Additionally, the closer the subject is to the composite camera, the greater the degree of angle of view adjustment can be. Therefore, it is possible to effectively photograph closer subjects.

Referring to FIG. 17, the first camera 5a has a first angle of view 15a. The second camera 5b has a second angle of view 15b. The third camera 5c has a third angle of view 15c. The fourth camera 5d has a fourth angle of view 15d. The fifth camera 5e has a fifth angle of view 15e. In the case of individual cameras (5a, 5b, 5c, 5d, 5e) without a piezoelectric transducer, a problem may occur in which cameras (5a, 5e) placed on the outside cannot photograph the subject (1) when taking close-up shots.

That is, the display device has a display panel that displays an image and one or more coupling parts for lens alignment in the non-display area of the display panel, and a camera into which a lens of the camera or an alignment pin arranged on the camera is inserted into the coupling part. It may contain more than one. The camera is a composite camera in which a plurality of cameras are arranged to be spaced apart at specific intervals, and may further include each piezoelectric transduction element disposed between each camera and the display panel. Each piezoelectric transduction element may be disposed adjacent to the corresponding alignment pin. The angle of view of each camera can be configured to be adjusted by each piezoelectric transduction element.

That is, the display device includes a display panel that displays an image, a plurality of coupling parts provided for lens alignment in a non-display area of the display panel, a plurality of cameras including alignment pins fastened to the plurality of coupling parts, and an aligner. It may include a plurality of piezoelectric transduction elements configured to control the angle of view of a plurality of cameras in response to the pin. The piezoelectric transduction element may be configured to expand or contract according to an applied control signal. The angles of view of the plurality of cameras can be adjusted in response to the macro mode.

In addition, the angle of view is adjusted using an alignment pin corresponding to the piezoelectric conversion element of each of the plurality of cameras included in the display device, and the display device adjusts the piezoelectric conversion element according to the distance from the surrounding cameras based on the central camera. Movement can be controlled. For example, as shown in FIG. 15, the control signal applied to the piezoelectric transduction element of the cameras 405b and 405d adjacent to the central camera 405c and the resulting angle adjustment are determined by the camera 405a and 405e on the boundary side. It can be configured to be smaller than the control signal applied to the piezoelectric transducer and the angle adjustment size resulting therefrom.

Although the above description focuses on the embodiments of the present invention, various changes and modifications can be made at the level of those skilled in the art. Accordingly, it will be understood that such changes and modifications are included within the scope of the present invention as long as they do not depart from the scope of the present invention.
