Therefore, the data lines arranged in the transparent area TA and the opaque area OA must be electrically connected to the common source driver 800 all together.

9 is a diagram showing a case where the common source driver 800 is disposed in the display device 100 according to the present embodiment and the sub pixels and data in the transparent area TA and opaque area OA of the display panel 110, Fig.

Referring to FIG. 9, one subpixel column in the transparent area TA may correspond to one subpixel column in the opaque area OA.

As described above, one subpixel line in the transparent area TA and one subpixel line in the opaque area OA are associated with each other, so that the patterning for the signal lines such as the subpixels, the data lines, and the like in the display panel 110 Can be relaxed.

9, when one subpixel column in the transparent area TA corresponds to one subpixel column in the opaque area OA, each subpixel column and opaque area OA , Each subpixel column can receive a data voltage from the same data lines DL2r1, DL2g1, DL2b1, DL2r2, DL2g2, DL2b2, ... arranged from the transparent area TA to the opaque area OA.

For example, the red subpixel lines in the transparent area TA and the red subpixel lines in the opaque area OA are connected to the same data lines DL2r1, DL2r2, ..., which are arranged from the transparent area TA to the opaque area OA. The data voltage can be supplied from the data line.

The green subpixel column in the transparent area TA and the green subpixel column in the opaque area OA are connected to the data line DL2g1, DL2g2, ... from the transparent area TA to the opaque area OA, Can be supplied.

As described above, by receiving the data voltages from the same data lines in each of the sub-pixel columns and the opaque regions OA in the transparent regions TA corresponding to each other, not only the formation of the data lines is easy, Since it is not necessary to change the data driving method, data driving for the transparent area TA and opaque area OA can be facilitated.

On the other hand, one subpixel column in the transparent area TA may correspond to two or more subpixel columns in the opaque area OA. Such a case will be described with reference to Figs. 10 and 11. Fig.

As described above, one subpixel column in the transparent area TA corresponds to two or more subpixel columns in the opaque area OA, thereby reducing the number of structures such as a black matrix and a bank formed at subpixel boundary points, The transparent area of the area TA can be widened and the transparency can be increased.

10 is a diagram showing a case where the common source driver 800 is disposed in the display device 100 according to the present embodiment and the subpixels and data in the transparent area TA and opaque area OA of the display panel 110, Figure 5 is another example layout for a line.

Referring to FIG. 10, one subpixel column SPC1r1 in the transparent area TA may correspond to two subpixel columns SPC2r1 and SPC2g1 in the opaque area OA.

In this case, out of the plurality of data lines DL2r1, DL2g1, DL2b1, DL2r2, DL2g2, DL2b2, ... supplying the data voltages to the plurality of sub-pixel lines in the opaque area OA, (DL2r1, DL2g1, DL2b1, ...) are arranged from the opaque area OA to the transparent area TA and the other half of the data lines DL2r2, DL2g2, DL2b2, OA).

According to the above description, the transparent area TA is provided with a smaller number of data lines than the opaque area OA, that is, by disposing half of the data lines compared to the opaque area OA, I can raise it.

Referring to FIG. 10, each subpixel column in the transparent area TA can receive a data voltage from the same data line as the subpixel column of the closest same color among the plurality of subpixel columns in the opaque area OA.

For example, the red subpixel column SPC1r1 in the transparent area TA is shifted from the data line DL2r1, which is the same as the nearest red subpixel column SPC2r1 in the opaque area OA, . The green subpixel column SPC1g1 in the transparent area TA is supplied with the data voltage from the data line DL2g1 which is the same as the nearest green subpixel column SPC2g1 among the plurality of subpixel columns in the opaque area OA. The blue subpixel column SPC1b1 in the transparent area TA is supplied with the data voltage from the same data line DL2b1 as the closest blue subpixel column SPC2b1 among the plurality of subpixel columns in the opaque area OA.

The length of the data lines DL2r1, DL2g1, DL2b1,... Arranged from the opaque area OA to the transparent area TA can be minimized, thereby reducing the data voltage transmission delay You can give.

11 shows the relationship between the subpixels and the data in the transparent area TA and the opaque area OA of the display panel 110 when the common source driver 800 is disposed in the display device 100 according to the present embodiments. Figure 5 is another exemplary layout for the line.

11, one subpixel column SPC1r1 in the transparent area TA may correspond to three subpixel columns SPC2r1, SPC2g1, and SPC2b1 in the opaque area OA.

In this case, among the plurality of data lines DL2r1, DL2g1, DL2b1, DL2r2, DL2g2, DL2b2,... Supplying data voltages to the plurality of subpixel lines in the opaque area OA, 1/3 data lines DL2r1, The data lines DL2g1, DL2b1, DL2r2, DL2b2, ... may be disposed only in the opaque area OA, while the data lines DL2g1, DL2g2, ... are arranged from the opaque area OA to the transparent area TA, .

According to the above description, a smaller number of data lines are arranged in the transparent area TA than in the opaque area OA, that is, 1/3 of the data lines are arranged in comparison with the opaque area OA, And transparency can be further increased.

Referring to FIG. 11, each subpixel column in the transparent area TA can receive a data voltage from the same data line as the subpixel column of the closest same color among the plurality of subpixel columns in the opaque area OA.

For example, the red subpixel column SPC1r1 in the transparent area TA is shifted from the data line DL2r1, which is the same as the nearest red subpixel column SPC2r1 in the opaque area OA, . The green subpixel column SPC1g1 in the transparent area TA is supplied with the data voltage from the same data line DL2g2 as the nearest green subpixel column SPC2g2 among the plurality of subpixel columns in the opaque area OA.

The length of the data lines DL2r1, DL2g2,... Arranged from the opaque area OA to the transparent area TA can be minimized, thereby reducing the data voltage transmission delay have.

The display panel 110 according to the above-described embodiments will be briefly described below.

The display panel 110 according to the present exemplary embodiment includes a transparent portion 211 and a first light emitting portion 212 disposed on a side surface of the transparent portion 211, A plurality of subpixels including a first circuit part 213 located under the first light emitting part 212 and a second light emitting part 222 disposed in the opaque area OA, And a second circuit portion 223 that is located on the first sub-pixel 223.

Here, a plurality of sub-pixels arranged in the transparent area TA can be arranged in the outer area within the display area A / A.

Therefore, by arranging at least one of the camera module 121 and the sensing module 122 or the like below the transparent area TA, the transparency of the transparent area TA can be used to capture the front side of the camera module 121, It is possible to detect the front of the vehicle 122 and the like.

In this case, since the camera module 121, the sensing module 122, and the like are not disposed outside the display panel 110, the ratio of the screen size to the device size can be maximized.

Accordingly, when the device size is constant, the bezel of the display apparatus 100 can be made smaller, and the screen can be enlarged as the bezel becomes smaller. Since the bezel of the display device 100 can be made smaller when the screen size is constant, the size of the device can be reduced.

On the other hand, in the display panel 110 according to the present embodiments, one subpixel column disposed in the transparent area TA may correspond to one subpixel column disposed in the opaque area OA.

As described above, one subpixel line in the transparent area TA and one subpixel line in the opaque area OA are associated with each other, so that the patterning for the signal lines such as the subpixels, the data lines, and the like in the display panel 110 Can be relaxed.

On the other hand, in the display panel 110 according to the present embodiment, all of the plurality of data lines arranged in the opaque area OA can be extended to the transparent area TA.

When all of the plurality of data lines arranged in the opaque area OA are extended to the transparent area TA, the data line formation can be made easier.

In addition, since each sub-pixel column in each of the sub-pixel columns and the opaque area OA in the transparent area TA corresponding to each other can receive the data voltage from the same data line, It is possible to easily provide data driving for the area TA and the opaque area OA.

On the other hand, in the display panel 110 according to the present embodiments, one subpixel column disposed in the transparent area TA may correspond to two or more subpixel columns disposed in the opaque area OA.

As described above, since one sub-pixel column in the transparent area TA corresponds to two or more sub-pixel columns in the opaque area OA, structures such as a black matrix and a bank formed at sub-pixel boundary points are reduced, The transparent area of the area TA can be widened and the transparency can be increased.

Meanwhile, in the display panel 110 according to the present embodiment, a plurality of data lines may be separately arranged in the transparent area TA and the opaque area OA.

As described above, by disposing the data lines separately in the transparent area TA and the opaque area OA, it is possible to provide independent data driving for the transparent area TA and opaque area OA.

On the other hand, in the display panel 110 according to the present embodiment, a part of the plurality of data lines arranged in the opaque area OA may be extended to the transparent area TA.

Therefore, a smaller number of data lines can be arranged in the transparent area TA than in the opaque area OA. Accordingly, the aperture ratio and transparency of the display panel 110 can be further increased.

For example, when one sub-pixel column disposed in the transparent area TA corresponds to two sub-pixel columns disposed in the opaque area OA, One half of the plurality of data lines supplying the data can be arranged from the opaque area OA to the transparent area TA and the remaining half can be arranged only in the opaque area OA.

In this case, in the transparent region TA, only half of the data lines can be arranged, compared to the opaque region OA. Accordingly, the aperture ratio and transparency of the display panel 110 can be increased.

In another example, when one subpixel row disposed in the transparent area TA corresponds to three subpixel columns disposed in the opaque area OA, data is divided into a plurality of subpixel rows arranged in the transparent area TA One third of the plurality of data lines supplying the voltage may be arranged from the opaque area OA to the transparent area TA and the remaining two thirds may be disposed only in the opaque area OA.

In this case, in the transparent area TA, only 1/3 of the data lines can be arranged as opposed to the opaque area OA. Accordingly, the aperture ratio and transparency of the display panel 110 can be further increased.

12, at least one of the camera module 121 and the sensing module 122 is disposed below the transparent area TA in the display area A / A of the display panel 110, , It is possible to photograph the front side of the camera module 121 or to detect the front side of the sensor module 122, for example.

In this case, since the camera module 121, the sensing module 122, and the like are not disposed outside the display panel 110, the ratio of the screen size to the device size can be maximized.

As shown in FIG. 12, when the device size S is constant, the bezel of the display device 100 can be made smaller and the size of the display area A / A can be increased as the bezel becomes smaller (H1 - > H2, H2 > H1).

Therefore, when the device size S is constant, the ratio of the screen size to the device size (H 1 / S -> H 2 / S, H 1 / S <H 2 / S) I can do it.

13 is a diagram for explaining a device size reduction effect according to the present embodiments.

12, at least one of the camera module 121 and the sensing module 122 is disposed below the transparent area TA in the display area A / A of the display panel 110, , It is possible to photograph the front side of the camera module 121 or to detect the front side of the sensor module 122, for example.

In this case, since the camera module 121, the sensing module 122, and the like are not disposed outside the display panel 110, the ratio of the screen size to the device size can be maximized.

13, when the size of the display area A / A, that is, the screen size H, is constant, the camera module 121, the sensing module 122, The bezel of the display device 100 can be made smaller and the size of the device can be made smaller as the bezel is smaller (S1 - > S2, S1 > S2).

Therefore, when the size of the display area A / A, that is, the screen size H is constant, the ratio of the screen size to the device size (H / S1-> H / S2, H / ), But the device size can be reduced (S1 &gt; S2).
