First, functions respectively corresponding to different regions in the display device 100 will be described.

Referring to fig. 1A, in a grand view, in the embodiment, the display device 100 has a display area DR and a non-display area NDR surrounding the display area DR. The non-display region NDR is located outside the display region DR and may also be referred to as a border region br (border region). In the present embodiment, the display area DR is an area for displaying an image in the display device 100, and the non-display area NDR is an area for disposing circuit elements or wires in the display device 100, but not limited thereto. In the embodiment of fig. 1A, the frame region BR surrounds the display region DR, but the invention is not limited thereto, for example, the frame region BR may be adjacent to one side or two sides of the display region DR, in other embodiments, the display region DR may also be circular or irregular, and the frame region BR is adjacent to or located at the periphery of the display region DR.

Referring to fig. 1B, the display device 100 has a display side DS and a back side BS opposite to each other. The display area DR faces the display side DS, and a user can view the image displayed in the display area DR at the display side DS. The rear side BS is the side facing away from the display side BS.

Referring to fig. 1A to fig. 1F, in the present embodiment, the display device 100 includes a substrate 110, a data driving circuit 120, a gate driving circuit 130, a plurality of data lines DL, a plurality of scan lines SL, and a functional module 140. The above elements are described in detail in the following paragraphs.

The substrate 110 is a semiconductor substrate formed by stacking a plurality of semiconductor layers, and is, for example, a pixel array substrate (pixel array substrate). In the embodiment, the substrate 110 is, for example, a Thin Film Transistor (TFT) substrate, but not limited thereto. The substrate 110 includes a plurality of pixels P. The pixels P are used for displaying an image frame in the display area DR of the display device 100. Referring to fig. 1A, fig. 1C and fig. 1D, the pixels P further include a plurality of first pixels P1 and a plurality of second pixels P2. The first pixels P1 are located in the first region DR1, and the second pixels P2 are located in the second region DR 2.

The data driving circuit 120 and the gate driving circuit 130 provide electrical signals to drive the pixels P according to the image data to display an image. Referring to fig. 1C, the data driving circuit 120 and the gate driving circuit 130 are disposed in the non-display region NDR and are disposed on different sides of the substrate 110. In other embodiments of the invention, the positions of the data driving circuit 120 and the gate driving circuit 130 may be adjusted according to different requirements, such as narrow frame, full screen, special display area shape, etc., for example, the data driving circuit is disposed on the same side of the display area DR or located in the display area DR, which is not limited thereto.

The data lines DL and the scan lines SL are respectively used for transmitting the electrical signals output by the data driving circuit 120 and the gate driving circuit 130 to the pixels P. Referring to fig. 1C, the data lines DL extend from the data driving circuit 120 to the display region DR, and the scan lines SL extend from the gate driving circuit 130 to the display region DR. According to different arrangement regions, the data lines DL and the scan lines SL can be divided into different groups of data lines and different groups of scan lines, and the grouping manner will be described in the following paragraphs.

Referring to fig. 1C and 1D, the data lines DL can be divided into a first group of data lines DL1 and a second group of data lines DL 2. In the present embodiment, the first group of data lines DL1 passes through the first region DR1 and the second region DR 2. The second group data line DL2 passes through the second region DR 2. It should be noted that, for clarity of illustration, fig. 1D omits the active device for controlling the pixel P, and only the data line and the scan line are connected to the pixel P or pass through the pixel P to briefly show the electrical connection relationship.

Similarly, the scan lines SL can be divided into a first group of scan lines SL1 and a second group of scan lines SL 2. In the present embodiment, the first group of scan lines SL1 passes through the first region DR1 and the second region DR 2. The second group scan lines SL2 pass through the second region DR 2.

In the embodiment, the functional module 140 is a module component capable of implementing various functions, and may be a camera module, a light intensity sensing module, an acoustic transceiver module, or other modules with different functions. The camera module is, for example, a module having an image pickup function. The light intensity sensing module is, for example, an optical sensing module for sensing the light intensity of the external light beam. The acoustic wave transceiver module is, for example, a module capable of transmitting an acoustic wave or sensing an acoustic wave. Referring to fig. 1B, in the embodiment, the function module 140 is embodied as a camera module 140 a. The camera module 140 includes an imaging module Len and an image sensor IS. The imaging module Len IS, for example, configured to receive an external light beam and form an image on a sensing surface of the image sensor IS by the external light beam. In an embodiment, the imaging module Len may be an optical imaging lens composed of a plurality of lenses with different diopters. In another embodiment, the imaging module Len may also be a lens array composed of a plurality of optical lenses arranged in an array. The invention is not so limited.

In the following paragraphs, the arrangement of the first pixels P1 and the second pixels P2, the circuit layout among the pixels P, the specific structure of each pixel P and the circuit layout in each pixel P, and the arrangement relationship between the first pixels P1 and the camera module 140a will be described in detail.

First, the arrangement of the first pixels P1 and the second pixels P2 is described.

In the present embodiment, the pixels P of the substrate 110 have different arrangement modes in different arrangement regions. Referring to fig. 1D, in the first region DR1 of the display region DR, the first pixels P1 are arranged in a ring shape. More specifically, the first region DR1 has a center point C1. The first pixels P1 radiate outward from the center point C1. More specifically, the first pixels P1 of different portions are substantially disposed along different directions D1, D2, D3 and D4 with the center point C1 as the center. The directions D1 to D4 are different from each other.

On the other hand, referring to fig. 1C and fig. 1D, in the second region DR2 of the display region DR, the second pixels P2 are arranged in a matrix manner.

Therefore, in the present embodiment, the first pixels P1 are arranged in the first region DR1 in a ring-shaped arrangement, and the second pixels P2 are arranged in the second region DR2 in a matrix. The circular arrangement is such that the number of pixels in the first region DR1 is less than the number of pixels in the second region DR2 in area density, which is defined as the number of pixels P in the region divided by the region area (i.e., the number of pixels P/the region area), as compared to the matrix arrangement. That is, according to the different arrangement of the pixels P, the resolution of the display image viewed by the user in the first region DR1 is low, and the resolution of the display image viewed in the second region DR2 is high. Therefore, the display image in the first region DR1 may display an image with low resolution requirement, for example, a pattern of battery power, network signal strength or time. The display in the second region DR2 can display images with higher resolution requirements.

Next, a circuit layout manner between the pixels P in the first region DR1 and the second region DR2 is described.

Referring to fig. 1C, fig. 1C shows a circuit layout of a second group of data lines DL2 and a second group of scan lines SL 2. Each of the second group data lines DL2 extends in the direction D1. Each second group of scan lines SL2 extends in the direction D2. In the embodiment, the direction D1 is substantially perpendicular to the direction D2, but the invention is not limited thereto, and in another modification, the direction D1 and the direction D2 may intersect at an angle greater than 180 degrees or less than 180 degrees, for example, the direction D2 may be horizontal as shown in fig. 1D, and the angle between the direction D1 and the direction D2 may be 150 degrees, so that the direction D1 is inclined by 30 degrees clockwise (the direction D1 in fig. 1D can be regarded as the vertical direction), and thus, the arrangement of the second pixels P2 may be varied. Each second group of data lines DL2 is electrically connected to the data driving circuit 120 and is electrically connected to a corresponding second pixel P2. Each second group of scan lines SL2 is electrically connected to the gate driving circuit 130 and to a corresponding second pixel P2.

Referring to fig. 1D, fig. 1D shows a circuit layout of the first group of data lines DL1 and the first group of scan lines SL 1.

In the present embodiment, each of the first group of data lines DL1 is electrically connected to the data driving circuit 120 and the corresponding at least one first pixel P1. In the following paragraphs, the first pixels P1 located at the upper left corner of the first region DR1_x～P1_wAn example of the electrical connection is illustrated.

In the first region DR1, the first group of data lines DL1 are connected to the first pixels P1, for example, one-to-one. The electrical connection relationship of the other first group of data lines DL1 is similar, and will not be described herein.

In the present embodiment, the first group of scan lines SL1 are electrically connected to at least one corresponding first pixel P1 and the gate driving circuit 130. The following paragraphs also refer to the first pixels P1 located at the upper left corner of the first region DR1_x～P1_wAn example of the electrical connection is illustrated.

In the first region DR1, a first group of scan lines SL1 is, for exampleAre connected one-to-many to the first pixels P1 arranged along the direction D4 and located at the upper left corner_x～P1_w. That is, the first pixels P1x, P1y, P1z, P1w share a single first group scan line SL 1. The electrical connection relationship of the other first group of scan lines SL1 is similar, and will not be described herein. In other words, in the embodiment of fig. 1D, the first pixels P1 located in the first region DR1 are arranged in a radial manner, and the plurality of first pixels P1 arranged in the same extending direction are electrically connected to the same scan line, such as the first pixel P1x, the first pixel P1y, the first pixel P1z and the first pixel P1w are arranged in the same extending direction (direction D4), and the same scan line (scan line SL1) is electrically connected to the first pixel P1x, the first pixel P1y, the first pixel P1z and the first pixel P1w, so that the first pixel P1x, the first pixel P1y, the first pixel P1z and the first pixel P1w are controlled by the same scan line. In addition, the first pixel P1x, the first pixel P1y, the first pixel P1z and the first pixel P1w are respectively driven by different data lines (DL1), so that the first pixel P1x, the first pixel P1y, the first pixel P1z and the first pixel P1w can be respectively driven by different voltage data, thereby generating different images. In this embodiment, the plurality of first pixels P1 may be arranged in a line, and each line extends toward the second region DR2 along different directions (e.g., the direction D1, the direction D2, the direction D3, and the direction D4 in fig. 1D) based on the center point C1 (the virtual center point C1), thereby forming a plurality of first pixels P1 radially arranged in the first region DR 1. In addition, the center point C1 of the first region DR1 may be the center of the actual first region DR1, but the present invention is not limited thereto, and the center point C1 may also be regarded as a virtual center, that is, only one position of the first region DR1 is not the actual center point, and the center point C1 is used as the position of the radial arrangement.

Therefore, in the display device 100 of the present embodiment, the data driving circuit 120 and the gate driving circuit 130 can control the first pixels P1 and the second pixels P2 in the first region DR1 and the second region DR2 by the circuit layout of the first group and the second group of data lines DL1 and DL2 and the first group and the second group of scan lines SL1 and SL2, so as to display an image.

Referring to fig. 1D again, the first pixels P1 in the first region DR1 are driven by the same scan line (a single first group scan line SL1) and data lines (a plurality of first group data lines DL 1). In other embodiments, the driving can be performed by the same data line (a single first group of data lines) and the plurality of scan lines (a plurality of first group of scan lines). In addition, in the embodiment, the data lines (the first group of data lines DL1) and the scan lines (the first group of scan lines SL1) of the first pixels P1 for controlling the first region DR1 are different from the data lines (the second group of data lines DL2) and the scan lines (the second group of scan lines SL2) of the second pixels P2 for controlling the second region DR2, i.e., the first pixels P1 and the second pixels P2 do not share the data lines and the scan lines, so that the advantage of independently driving the display in different regions (the first region DR1 or the second region DR2) can be realized by such a circuit design. In other embodiments, the first scan line SL1 and the first data line DL1 may also be electrically connected to at least part of the second pixels P2 in the second region DR, that is, the first pixels P1 and the second pixels P2 share data lines and scan lines, which is not limited by the disclosure.

Next, the specific structure of each pixel P will be described.

In the present embodiment, the architecture of the first pixel P1 disposed in the first region DR1 is different from the architecture of the second pixel P2 disposed in the second region DR 2. The difference between the first pixel P1 and the second pixel P2 will be described in the following paragraphs.

Referring to fig. 1D and 1E, the first pixel P1 includes a plurality of Sub-pixels SP1 (three for example) and a penetration region TR. The second pixel P2 includes a plurality of second sub-pixels SP2 (three for example). Since the first pixel P1 has a more transmissive region TR than the second pixel P2, the transmittance of the first pixel P1 is higher than that of the second pixel P2. In addition, the area of the first pixel P1 is larger than that of the second pixel P2 in terms of size.

Referring to fig. 1E, each of the first and second sub-pixels SP1 and SP2 includes a plurality of active devices T (as switching devices) and a plurality of light emitting devices E. The first sub-pixels SP1 respectively include a plurality of light emitting elements R1, G1, B1 with different light emitting colors, and the light emitting elements R1, G1, B1 are electrically connected to the active elements T1 to T3, respectively. The second sub-pixels SP2 also include a plurality of light emitting devices R2, G2, B2 with different colors, and the light emitting devices R2, G2, B2 are electrically connected to the active devices T4 to T6, respectively. In detail, in the present embodiment, the first sub-pixel SP1R and the second sub-pixel SP2R respectively include red light emitting devices R1 and R2 with red light emitting color. The first sub-pixel SP1G and the second sub-pixel SP2G include green light emitting elements G1 and G2, respectively, which emit green light. The first sub-pixel SP1B and the second sub-pixel SP2B include blue light emitting elements B1 and B2, respectively, which emit blue light. In other embodiments, the first and second sub-pixels SP1, SP2 may also have other light emitting elements with different light emitting colors according to different requirements, which is not limited in the present invention.

Referring to fig. 1F, in order to illustrate the specific structure of the first pixel P1 of the substrate 110, only the first sub-pixel SP1 of the first pixel P1 is taken as an example, and the rest of the second sub-pixel SP2, the third sub-pixel SP3 and so on.

The first sub-pixel SP1R is disposed on the substrate SB, and the first sub-pixel SP1R includes an active device T1, a red light emitting device R1, insulating layers I1, I2, and a pixel defining layer PDL.

In the present embodiment, the active device T1 is, for example, a Thin Film Transistor (TFT) including a channel layer CH, a gate G, a source D and a drain S. The channel layer CH, the gate G, the source D and the drain S are stacked on the substrate SB. The gate G is electrically connected to the corresponding scan line SL, and is electrically connected to the gate driving circuit 130 through the scan line SL. The gate G overlaps the channel layer CH, and a gate insulating layer GI is sandwiched between the gate G and the channel layer CH. The source S and the drain D are located on the channel layer CH and electrically connected to the channel layer CH. The source S is electrically connected to the corresponding data line DL, and is electrically connected to the data driving circuit 120 through the corresponding data line DL.

The active device T is a bottom gate thin film transistor, but the invention is not limited thereto. In other embodiments, the active device T may also be a top gate type or other type of thin film transistor.

In the present embodiment, the Light Emitting element provided in the first sub-pixel SP1 is, for example, an Organic Light Emitting Diode (OLED). Specifically, the red light emitting element R1 includes a light emitting layer EL, an electrode layer a1, and an electrode layer a 2. The light emitting layer EL is sandwiched between the electrode layer a1 and the electrode layer a2, and the electrode layers a1 and a2 are electrically connected, wherein the electrode layer a1 is, for example, a Cathode (Cathode), and the electrode layer a2 is, for example, an Anode (Anode), but not limited thereto. The material of the light emitting layer EL is, for example, an organic light emitting material, and is, for example, an organic light emitting material which can emit red light after being electroluminescence.

The insulating layers I1 and I2 are disposed between the red light emitting device R1 and the active device T1. A conductive via hole penetrates through the insulating layers I1, I2, one end of the via hole is connected to the electrode layer a2, and the other end is connected to the drain D.

The pixel defining layer PDL, which may also be referred to as a pixel defining layer, covers the active element T1 of the first sub-pixel SP1R and exposes the region of the first sub-pixel SP1R where the light emitting layer EL is formed. The pixel defining layer PDL is further used to separate the light emitting layers in the other first sub-pixels SP 1.

Further, a penetration region TR is provided beside the first subpixel SP 1. In the present embodiment, the transparent region TR is disposed therein, and is made of a transparent material, such as air or glass, but not limited thereto. In fig. 1F, the penetration region TR is provided with the substrate SB and no other layer. In other embodiments, one or more insulating layers or light-emitting layers may be selectively disposed according to the process requirements. It should be noted that the transmission region TR is not provided with a layer for reducing the light transmittance, for example, the transmission region TR is not provided with a metal layer (for example, a cathode of an organic light emitting diode). Specifically, in the embodiment of fig. 1F, each layer, such as the insulating layer, the light emitting layer, the metal layer, etc., forms an opening in the transmissive region TR to increase the transmittance of the transmissive region TR (compared to other regions), but the invention is not limited thereto, and in other variations, a portion of the insulating layer is still disposed in the transmissive region TR, and the light emitting layer and the metal layer are formed with openings in the transmissive region TR to make the transmissive region TR include the substrate SB and the insulating layer (such as the gate insulating layer GI, the insulating layer I1, or the insulating layer I2, etc.).

Thus, the structure of the first sub-pixel SP1R and the transmission region TR is roughly described. The difference between the architectures of the first sub-pixel SP1G, the first sub-pixel SP1B, and so on is that: the material of the corresponding light emitting layer EL is an organic light emitting material capable of emitting green light and blue light after electroluminescence.

The second sub-pixel SP2R of the second pixel P2 of the substrate 110 is similar to the first sub-pixel SP1R in structure, and the difference is that: the transmissive region TR is not disposed in the second sub-pixel SP2R, and thus will not be described in detail. The second sub-pixels SP2G and SP2B are similar to the second sub-pixel SP2R, and the difference is: the material of the corresponding light emitting layer EL is an organic light emitting material capable of emitting green light and blue light after electroluminescence.

In addition, in the above embodiments, the light emitting device is implemented by taking an organic light emitting diode as an example, but the invention is not limited thereto. In other embodiments, the light emitting device can be replaced by a submillimeter light emitting diode (Mini LED) or a Micro LED (Micro LED), wherein the submillimeter light emitting diode has a size falling within a range of 100 micrometers to 200 micrometers, and the Micro LED has a size in a micrometer scale, for example, the size is smaller than 100 micrometers and larger than 0 micrometer, which is not limited by the disclosure. The size of the led is defined by the length of the diagonal line of the top view of the led, for example, but the invention is not limited thereto.

Next, a circuit layout manner in each pixel P (the first pixel P1, the second pixel P2) will be described.

Referring to fig. 1D, the first pixel P1x is taken as an example for illustrating the circuit layout. Referring to fig. 1E, before entering the first pixel P1x, the first group of data lines DL1 is divided into three sub-data lines, which are electrically connected to the active devices T1 to T3, respectively. The first group of scan lines SL1 are electrically connected to the active devices T1-T3.

Similarly, the circuit layout of the second pixel P2 is similar to that of the first pixel P1, and the description thereof is omitted, except that: the second group of scan lines SL2 and the second group of data lines DL2 are used.

It should be noted that the circuit layout method described above is only an exemplary circuit layout method. In other embodiments, different circuit layouts may be designed according to different pixel arrangement manners, and the present invention is not limited to the above-mentioned circuit layouts as long as the layout manners are such that the first pixels P1 and the second pixels P2 are electrically connected to the data lines DL and the scan lines SL.

Finally, the configuration relationship between these first pixels P1 and the camera module 140a is described.

Referring to fig. 1B and 1D, in the present embodiment, the camera module 140a may be disposed on the back side BS of the display device 100 and correspondingly disposed on the substrate 110 on the back side of the first region DR 1. In the present embodiment, the display device 100 is arranged in a ring arrangement by the first pixels P1 of the first region DR1 disposed in the display region DR, and thus the transmittance of the first region DR1 is higher than that of the second region DR 2. If the camera module 140a of the display device 100 is disposed in the first region DR1 and on the back side BS, the camera module 140a can capture an external light beam to sense an image. Meanwhile, the display device 100 may control the first pixels P1 located in the first region DR1 and the second pixels P2 located in the second region DR2 to display an image together. Therefore, the display device 100 of the present embodiment can realize a high screen ratio design.

Further, in the present embodiment, the camera module 140a and the arrangement of the first pixels P1 have a corresponding relationship. Referring to fig. 1B and fig. 1D, for example, the center point C2 of the orthogonal projection OP of the camera module 140a on the substrate 110 overlaps the center point C1 of the first pixels P1 arranged in a ring shape. In this way, the optical acquisition quality of the camera module 140a at the rear end of the substrate 110 can be further improved by the annularly arranged pixel arrangement.

In other embodiments, the camera module 140a can be replaced with a functional module having other functions, which is not limited in the disclosure.

It should be noted that the following embodiments follow the reference numerals and parts of the contents of the above embodiments, wherein the same or similar reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted. For the description of the omitted parts, reference may be made to the foregoing embodiments, which are not repeated herein.

Fig. 2 to 5 are enlarged schematic views of different embodiments of the region B in fig. 1A. It should be noted that the data lines and the scan lines are not shown in fig. 2 to 4 for clarity.

Referring to fig. 2, the arrangement of the first pixels P1 in the first region DR1 in the display device 100 of fig. 1A and 1B may be different from that of fig. 1D, and fig. 2 shows a possible arrangement, which is mainly different from that of fig. 1D: in fig. 2, the first pixels P1 are arranged in a plurality of concentric circles CC centered on the center point C1, and are arranged in a sequence of three concentric circles CC1, CC2, and CC3 from the center point C1 along the radial direction outwards.

Referring to fig. 3, the arrangement of the first pixels P1 in the first region DR1 in the display device 100 of fig. 1A and 1B may be different from that of fig. 1D and 2, and fig. 3 shows another possible arrangement, which is mainly different from that of fig. 3, 2 and 1D: in fig. 3, the first pixels P1 are arranged in a plurality of concentric circles CC 'with the center point C1 as the center, and are arranged in three concentric circles CC 1', CC2 'and CC 3' from the center point C1 outwards in sequence along the radial direction. Also, two adjacent first pixels P1 in each concentric circle CC' have a pitch DS. The concentric circles CC1 ', CC2 ', CC3 ' have spacings DS1, DS2, DS3, respectively. These spacings DS1, DS2, DS3 increase radially outward from the center point C1.

From another perspective, each of the concentric circles CC ' in fig. 3 has a different linear density of the number of pixels, and the concentric circles CC ' respectively have a linear density of the number of pixels decreasing from the center point C1 radially outward, wherein the linear density of the number of pixels is defined as the number of pixels used by the concentric circles CC ' divided by the circumference of the concentric circles CC ' (i.e., the number of first pixels P1 used by each concentric circle CC/the circumference of the corresponding concentric circle CC ').

Referring to fig. 4, the pixel arrangement of fig. 4 is substantially similar to that of fig. 1D, and the main differences are: in fig. 4, the pixels P further include a plurality of compensation pixels SP. The compensation pixels SP are disposed in the first region DR1, and the area occupied by the compensation pixels SP in the first region DR1 does not overlap the area occupied by the first pixels P1 in the first region DR 1. In other words, the compensation pixels SP are located between the first pixels P1 and the second pixels P2, so that the image resolution of the image displayed in the first region DR1 can be further improved. The structure of the compensation pixel SP is similar to that of the first pixel P1 and will not be described herein.

Referring to fig. 5, the pixel arrangement of fig. 5 is substantially similar to that of fig. 1D, and the main difference is the circuit layout: in fig. 5, the active devices T are not disposed in the first pixels P1, but are disposed outside the first pixels P1. These first pixels, which are arranged along the direction D4 and located at the upper left corner, are illustrated. After the first data line DL1 and the first scan line SL1 are electrically connected to the active device T, the first data line DL1 and the first scan line SL1 are electrically connected to the first pixels at the upper left corner by wires, respectively. In the present embodiment, the penetration degree of the first region DR1 can be further increased by the above arrangement. Therefore, when the functional module 140 (e.g., camera module, photo-detection module, etc.) is applied to the display device having the circuit layout shown in fig. 5, the light-receiving amount and the detection performance can be improved.

In summary, in the display device of the embodiment of the invention, the first pixels arranged in a ring shape are disposed in the first area of the display area, so that the required functional modules can be correspondingly disposed, and the functional design can have more flexibility in adjustment. Besides, the display device can execute the function of the function module, and can display the picture by controlling the plurality of first pixels in the first area and the plurality of second pixels in the second area together, so that the functions of displaying the picture and executing the function module are realized simultaneously, and the display device has the advantages of high screen occupation ratio and multi-function application.

For example, the functional module may be a camera module, and the camera module is disposed on the back side of the display device and correspondingly disposed in the first region. Accordingly, the display device can display a picture, and can realize the image pickup function of the camera module through the high transmittance of the first area. Further, the camera module can be matched with the annular arrangement mode of the first pixels to improve the optical acquisition quality.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
