Be equipped with camera 60 in the electronic equipment 10, camera 60 includes the camera lens, and the camera lens of camera 60 sets up towards first display area 220, and camera 60 is used for acquireing the external light signal who passes through first display area 220 and forms images. It can also be understood that the camera 60 is disposed below the first display area 220 of the display device 20, and the camera 60 is configured to acquire an ambient light signal transmitted through the first display area 220 of the display device 20 and form an image according to the acquired ambient light signal. The display area of the display device 20 is complete, a light transmission channel which cannot be displayed is not arranged due to the camera 60, the screen ratio of the display device 20 is improved, a real full-screen can be provided, and images can be displayed in a full screen mode. The camera 60 may be a front camera 60 of the electronic device 10, and the camera 60 may be used to obtain images of a user, such as a self-photograph, through the first display area 220 of the display device 20.

In order to more fully understand the display device of the embodiments of the present application. The display device will be described in detail below. Referring to fig. 2, fig. 2 is a schematic structural diagram of a display device of the electronic apparatus shown in fig. 1. The display device 20 in the embodiment of the present application may include a first display area 220 and a second display area 240 that are adjacent. Both the first display area 220 and the second display area 240 may be used to display text or images, and the first display area 220 and the second display area 240 may collectively display the same image. For example, the first display area 220 displays a portion of the preset image, and the second display area 240 displays the remaining portion of the preset image. The first display area 220 and the second display area 240 may also display different images. For example, the first display area 220 displays a taskbar image and the second display area 240 displays a preset image. Both the first display area 220 and the second display area 240 can display contents, the display area is complete, and the screen occupation ratio of the display device 20 is high. The second display area 240 may surround the first display area 220, and the periphery of the first display area 220 may be adjacent to the second display area 240, that is, the first display area 220 is located in the middle of the second display area 240. The second display area 240 may also partially surround the first display area 220, and a part of the edge of the first display area 220 is adjacent to the second display area 240, for example, the first display area 220 is located at a corner of the display device 20 or located in the middle of the top end of the display device 20.

Referring to fig. 3, fig. 3 is a schematic partial cross-sectional view of the display device shown in fig. 2 along the direction AA. The second display area 240 includes a thin film transistor 260, and the thin film transistor 260 is used for driving the pixels of the display device 20 to display an image. Illustratively, the thin film crystal may be used to drive the second pixels of the second display region to display an image.

The first display area 220 is for allowing the camera 60 to obtain more external light signals, the overall transmittance of the first display area 220 is higher, the external light signals can enter the electronic device through the first display area 220, and when the external light signals penetrate through the first display area 220, a part of the external light signals can irradiate on the thin film transistor 260 of the second display area 240 through the first display area 220 due to the angle of the external light signals and other reasons. In addition, when the first display area 220 displays an image, the light signal emitted by the first pixel 2262 of the first display area 220 is scattered in all directions, and a portion of the light signal is irradiated onto the thin film transistor 260 of the second display area 240. The tft 260 in the second display area 240 is exposed to light and affects the photoelectric effect of the tft 260, which causes the leakage current of the tft 260 to change, and thus non-uniform (mura) stripes are generated when the tft 260 controls the display of the second pixel.

To solve the above problem, a light shielding portion may be disposed between the first display area and the second display area, specifically please refer to fig. 4 to 6, fig. 4 is a second structural schematic diagram of the electronic device according to the embodiment of the present application, fig. 5 is a first partial structural schematic diagram of the display device of the electronic device shown in fig. 4, and fig. 6 is a first partial cross-sectional schematic diagram of the display device shown in fig. 5 along the BB direction. The light shielding portion 280 is disposed between the first display region 220 and the second display region 240, and disposed around the first display region 220, for shielding the optical signal irradiated from the first display region 220 to the thin film transistor 260 of the second display region 240, so as to reduce the influence on the photoelectric characteristic of the thin film transistor 260 of the second display region 240, thereby ensuring the display effect of the display region driven by the thin film transistor 260. The light shielding portion may shield the external light signal from being irradiated from the first display region 220 to the thin film transistor 260 of the second display region 240 during the external light signal is transmitted through the first display region 220. When the first pixel of the first display region 220 emits the optical signal, the light shielding portion may also shield the optical signal from the first display region 220 to the thin film transistor 260 of the second display region 240. Therefore, the influence of the first display area 220 on the photoelectric effect of the thin film transistor 260 is reduced, and the leakage current of the thin film transistor 260 is not changed due to the first display area 220, so that mura stripes are not generated in the first display area 220 when the thin film transistor 260 controls the second pixel display of the second display area 240.

Here, when the second display area 240 surrounds the first display area 220, the light shielding portion 280 surrounds the entire first display area 220. When the second display area 240 partially surrounds the first display area 220, a partial edge of the first display area 220 is adjacent to the second display area 240, for example, the first display area 220 is located at a corner of the display device 20 or at the middle of the top end of the display device 20, and the light shielding portion 280 may surround a portion of the first display area 220 adjacent to the second display area, or may surround the entire first display area.

It should be noted that, if there is no light shielding portion, since the external light signal is irregular, the light signal emitted by the first pixel in the first display area is also irregular, and the external light signal or the light signal emitted by the first pixel may undergo multiple refractions and/or reflections in the display device during the process of being irradiated onto the thin film transistor, that is, the light signal of the first pixel irradiated onto the thin film transistor is also irregular. And the first pixel also comprises three sub-pixels of RGB, the change after the three sub-pixels of RGB are irradiated to ambient light is different, the light signal that three kinds of sub-pixels of RGB send out is also different, cause the correspondent mura stripe that produces of TFT to be irregular and extremely complicated dynamic change, can't clear away the stripe of this mura effectively through the demura way of the software. Therefore, the display device can be prevented from generating the irregular mura stripes by the light shielding portion.

It is understood that the second display area may generate mura stripes due to the distribution of the second pixels, etc., but because the arrangement of the second pixels is regular, the corresponding mura stripes are also regular, and the mura stripes can be eliminated by using the demura method of the software.

Referring to FIG. 7, FIG. 7 is a second partial cross-sectional view of the display device shown in FIG. 5 along the direction BB. The display device 20 may include an anode layer 224 and a pixel layer 226 adjacent to each other, and it is understood that since both the first display area 220 and the second display area 240 are displayable, both the anode layer 224 and the pixel layer 226 are laid on the first display area 220 and the second display area 240. The light shielding portion 280 may be disposed on a side of the anode layer 224 facing away from the pixel layer 226. Since the thin film transistors 260 are generally disposed under the anode layer 224, i.e., on the side of the anode layer 224 away from the pixel layer 226, the light shielding portion 280 is correspondingly disposed under the anode layer 224 for shielding the light signals from the first display area 220 to the thin film transistors 260 of the second display area 240.

It should be noted that the anode layer 224 includes a reflective anode disposed below the corresponding pixel, the reflective anode is used to reflect the optical signal emitted by the pixel out of the display device 20, so as to improve the brightness of the display device 20, and the reflective anode is generally made of an opaque material, such as a metal or an alloy, so that the light shielding portion 280 can be disposed below the anode layer 224 including the reflective anode, i.e., the electrical connection between the anode layer 224 and the pixel layer 226 is not affected, and the light signal irradiated from the first display area 220 into the second display area 240 is not affected.

With reference to fig. 7, the display device 20 may further include a first substrate 221 and an intermediate layer 222, the first substrate 221 is connected to the anode layer 224 through the intermediate layer 222, and it can also be understood that the display device 20 sequentially includes the first substrate 221, the intermediate layer 222, the anode layer 224 and the pixel layer 226, wherein the light shielding portion 280 is disposed on the intermediate layer 222, that is, the light shielding portion 280 is disposed between the first substrate 221 and the anode layer 224.

The light shielding portion 280 may completely penetrate the intermediate layer 222. That is, one end of the light shielding portion 280 abuts the first substrate 221, and the other end of the light shielding portion 280 abuts the anode layer 224 or the pixel layer 226. For example, the intermediate layer 222 may be disposed on the first substrate 221, and then a gap communicating with the first substrate 221 is etched on the intermediate layer 222, and then the light shielding portion 280 is disposed in the gap.

The light shielding portion may be provided in the middle of the intermediate layer. Illustratively, referring to fig. 8, fig. 8 is a third partial cross-sectional view of the display device shown in fig. 5 along the BB direction.

The intermediate layer 222 is first disposed on the first substrate 221, then a receiving groove with an opening facing the anode layer 224 is etched in the intermediate layer 222, then the light shielding portion 280 is disposed in the receiving groove, but the light shielding portion 280 does not fill the groove 2212, and then the same material as the intermediate layer 222 is disposed on the light shielding portion 280, so that the light shielding portion 280 is completely disposed inside the intermediate layer 222.

The light shielding portion may partially penetrate the intermediate layer. If the middle layer is provided with a containing groove, the opening of the containing groove can face the first base material and also can face the anode layer, and the shading part is arranged in the containing groove. For example, the light shielding portion may be disposed on the first substrate, and then the intermediate layer may be disposed, and the intermediate layer covers the first substrate, thereby forming the accommodating groove with the opening facing the first substrate. The first substrate may be provided with an intermediate layer, the intermediate layer is etched to form an accommodating groove with an opening facing the anode layer, and the accommodating groove is provided with a light-shielding portion.

The shading part and the first base material can also have other matching structures. Referring to fig. 9, fig. 9 is a fourth partial cross-sectional view of the display device shown in fig. 5 along the BB direction. The first substrate 221 is provided with a groove 2212, and the light shielding portion 280 is partially disposed in the groove 2212. Since the first substrate 221 is generally made of a highly light-transmitting material, such as glass, resin, etc., a part of the optical signal may also enter the second display area 240 from the first display area 220 through the first substrate 221, and irradiate the thin film transistor 260 of the second display area 240 through refraction, reflection, etc. Accordingly, the light shielding portion 280 is partially disposed in the groove 2212 of the first base material 221, thereby shielding more optical signals. It will be appreciated that the end of the light shield facing away from the first substrate may be located within the intermediate layer or may abut the anode layer.

The light shielding portion 280 in the embodiment of the present application may be perpendicular to the first substrate 221, so as to better shield the light signal incident from the first display area 220 toward the second display area 240. Of course, the light shielding portion may be disposed not perpendicular to the first base material. Illustratively, one end of the light shielding portion is adjacent to the anode layer in the second display and the other end is adjacent to the first substrate of the first display region, or one end of the light shielding portion is adjacent to the first substrate of the first display region and the other end is adjacent to the anode layer in the second display.

The light shielding part can be partially positioned in the first display area and partially positioned in the second display area, or can be positioned in the first display area or the second display area as a whole. For example, referring to fig. 10, fig. 10 is a schematic partial cross-sectional view of the display device shown in fig. 5 along the BB direction. The light shielding portion 280 may also be disposed in the second display area 240 and adjacent to the first display area 220, or the light shielding portion may also be disposed in the second display area but not adjacent to the first display area. For example, please refer to fig. 11, fig. 11 is a schematic partial cross-sectional view of a display device of an electronic apparatus according to an embodiment of the present disclosure. The light shielding portion 280 is disposed in the first display region 220 and adjacent to the second display region 240, or the light shielding portion is disposed in the first display region but not adjacent to the second display region.

The position of the shading part can be reasonably arranged according to the requirement, so that the manufacturing process is convenient. The thickness of the light shielding portion may be set as needed, and for example, the light shielding portion may penetrate through the intermediate layer or may be set in the intermediate layer, and the thickness of the light shielding portion is not limited herein.

The display device further includes a first driving unit for driving the plurality of first pixels in the first display region, and the first driving unit may be disposed in the first display region, thereby more conveniently driving the first pixels. The first driving unit may also be disposed outside the first display region to improve light transmittance of the first display region.

When the first driving unit may also be disposed outside the first display region, the first driving unit may be disposed in the second display region or the non-display region of the display device. Referring to fig. 12 and 13, fig. 12 is a second partial structure diagram of the display device of the electronic apparatus shown in fig. 4, and fig. 13 is an enlarged diagram of an X portion of the display device shown in fig. 12. The first driving unit 2264 is disposed in the second display area 240, and the first driving unit 2264 can drive the first pixel 2262.

It should be noted that, the first driving unit also includes a thin film transistor, and if the thin film transistor of the first driving unit is irradiated by the optical signal from the first display area, the mura stripe of the first display area is also caused, and the mura stripe is also irregular and very complicated dynamic mura stripe, and the light shielding portion can also eliminate the mura stripe.

It should be noted that the first driving unit 2264 also includes the thin film transistor 260, and if the thin film transistor 260 of the first driving unit 2264 is irradiated by the light signal from the first display area 220, the mura stripe of the first display area 220 is also caused, and is also an irregular very complex dynamic mura stripe, and the light shielding portion 280 can also eliminate the portion of the mura stripe.

Specifically, the pixel layer 226 of the first display region includes a plurality of first pixels 2262. The first pixel 2262 is an organic light emitting unit, the first pixel 2262 may include a plurality of sub-pixels (not shown), and the first pixel 2262 may display a plurality of colors by cooperation between the plurality of sub-pixels. The first pixel 2262 may include three subpixels of red, green and blue or other subpixels. The first pixel 2262 includes different numbers of sub-pixels according to the arrangement of the sub-pixels. For example, the first pixel 2262 may include three sub-pixels of red, green and blue, four sub-pixels of red, green and blue, etc., and the number and arrangement of the sub-pixels included in the first pixel 2262 are not limited herein.

Referring to fig. 14, fig. 14 is a schematic structural diagram of a first pixel and a reflective anode in a first display area of a display device according to an embodiment of the present disclosure. The anode layer 224 of the first display region includes a plurality of reflective anodes 2242, and the plurality of reflective anodes 2242 are electrically connected to the plurality of first pixels 2262, which can also be understood as that each reflective anode 2242 is electrically connected to one first pixel 2262. The reflective anode 2242 may be used to drive the first pixel 2262 to emit light, and may also emit a light signal emitted by the first pixel 2262, so as to improve the light emitting efficiency of the first display area 220. It will be appreciated that the emitting anode is formed of a material that is opaque to light, for example the emitting anode is formed of a metal material that is opaque to light.

The first pixel 2262 is made of an organic material, and the first pixel 2262 has a better light transmittance, i.e., an external light signal can transmit through the first pixel 2262. However, in order to increase the display brightness of the first display area 220, the reflective anode 2242 may be disposed directly below the first pixel 2262 and has a size greater than or equal to that of the first pixel 2262, and it is also understood that the orthographic projection of each first pixel 2262 on the anode layer 224 is located in one reflective anode 2242, so that the light signal emitted by the first pixel 2262 is emitted as far as possible, and a better display brightness is obtained. In addition, the first pixel 2262 includes a plurality of sub-pixels with different colors, and the optical parameters of the sub-pixels with different colors are different, so that if the camera 60 obtains an external light signal passing through the first pixel 2262 to form an image, it is difficult to process the light signal passing through the sub-pixels with different colors, and it is also necessary to process the light signal not passing through the first pixel 2262. Therefore, the orthographic projection of each first pixel 2262 on the anode layer 224 is located in a reflective anode 2242, so that the uniformity of the light transmitted through the first display area 220 can be improved, and the imaging quality through the first display area 220 can be improved.

Referring to fig. 15, fig. 15 is a schematic partial cross-sectional view of the display device shown in fig. 5 along the BB direction. The first driving unit 2264 is connected to the anode layer 224 via the connection lines 2224 to drive the first pixels 2262. The connection line 2224 may be disposed at the anode layer 224 and between the light shielding portion and the pixel layer 226. The connection line 2224 is disposed at the anode layer 224, and may facilitate wiring in the first display region 220.

Referring to fig. 16, fig. 16 is a schematic partial cross-sectional view of the sixth display device shown in fig. 5 along the BB direction. The connecting lines 2224 may also be disposed between the first substrate 221 and the intermediate layer 222, and between the light shielding portion and the first substrate 221. Because the gate lines and the data lines for driving the second pixels 242 are disposed in the second display region 240 and the gate lines and the data lines are disposed corresponding to each of the second pixels 242, the control lines corresponding to each of the first pixels 2262 may be disposed in the first display region 220 and correspond to the corresponding first driving units 2264, the intermediate layer 222 in the first display region 220 may have a via hole corresponding to each of the first pixels 2262 and is connected to the control lines through the conductive lines in the via holes, and the control lines and the conductive lines form the connection lines 2224 for connecting the anode layer 224 of the first display region 220 and the first driving units 2264. The connection line 2224 may be formed of a conductive material with high light transmittance, such as an Indium Tin Oxide (ITO) material.

When the first driving units are disposed in the second display region, each of the first driving units may be disposed between a plurality of the second driving units. In order to better dispose the first driving unit in the second display region, the first driving unit may employ a simplified driving circuit. For example, the first driving unit may adopt a driving circuit of 2T1C or 5T1C and the second driving unit adopts a driving circuit, so as to obtain better driving effect.

In order to more easily dispose the first driving units in the second display region, the total number of the first driving units may be reduced. Specifically, a plurality of first pixels may be arranged in parallel, that is, one first driving unit may drive a plurality of first pixels, thereby reducing the number of first driving units and facilitating the first driving unit to be arranged in the second display region.

The intermediate layer 222 of the second display region 240 includes a plurality of layer structures, for example, the intermediate layer 222 may include an insulating layer 225 in addition to the driving layer 223. In other embodiments, the intermediate layer may further include a gate line layer, a data line layer, a plurality of insulating layers, and the like. The light shielding portion 280 may be disposed at the driving layer 223 without affecting other layer structures.

If the first driving unit is not disposed in the first display region, the first display region may be filled with a material with high light transmittance without disposing a driving layer.

In some embodiments, please refer to fig. 18, fig. 18 is a schematic cross-sectional view of a second portion of a second display area of a display device according to an embodiment of the present disclosure. A light-shielding layer 227 may be disposed between the driving layer 223 and the pixel layer 226 of the second display region 240 so that an external light signal or a light signal emitted from the second pixel 242 does not irradiate the second driving unit 244, and when the light-shielding portion 280 is disposed in the second display region 240, the light-shielding portion 280 may be adjacent to the light-shielding layer 227. The light-shielding layer 227 may be made of an insulating material that can shield light, and the light-shielding layer 227 may achieve both a light-shielding effect and an insulating effect, and the light-shielding layer may directly adjoin the anode layer. In some other embodiments, an insulating layer may be disposed between the light-shielding layer and the pixel layer in addition to the anode layer. Of course, the light-shielding portion may penetrate the light-shielding layer or be partially provided in the light-shielding layer. It is understood that the first display region may not be provided with the light-shielding layer to improve light transmittance.

The light transmittance of the second display region is less than that of the first display region and can be realized by various structures. Wherein, can be realized by the structure of the pixel distribution density. Specifically, the distribution density of the plurality of second pixels in the second display area is greater than the distribution density of the plurality of first pixels in the first display area. Referring to fig. 19, fig. 19 is a second enlarged view of a portion X of the display device shown in fig. 12. The size of the second pixels 242 may be the same as that of the first pixels 2262, and the spacing between the first pixels 2262 of the first display region 220 is larger, which may improve the light transmittance of the first display region 220. For example, the distribution density of the first pixels 2262 in the first display area 220 is 200ppi, and the distribution density of the second pixels 242 in the second display area 240 may reach 400ppi or more. In another example, please refer to fig. 20, and fig. 20 is a third enlarged schematic view of a portion X of the display device shown in fig. 12. The size of the first pixels 2262 of the first display area 220 may be larger than the size of the second pixels 242 of the second display area 240, and the pitch between the first pixels 2262 is positively correlated with the size of the first pixels 2262, that is, the larger the size of the first pixels 2262 is, the larger the spacing distance between the first pixels 2262 is, and therefore, the distribution density of the first pixels 2262 of the first display area 220 is larger than the distribution density of the second pixels 242 of the second display area 240.

It can be understood that the distribution density of the first pixels of the first display area is less than the distribution density of the second pixels of the second display area, and the smaller the distribution density of the first pixels, the larger the area ratio of the first pixels with higher light transmittance is, so as to realize that the light transmittance of the first display area is greater than that of the second display area. And the first driving unit for driving the first display area is arranged in the first display area, and the second driving unit for driving the second pixel is arranged in the second display area, so that the light transmittance of the first display area is more greater than that of the second display area.
