Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic view illustrating a first structure of a display device according to an embodiment of the present disclosure. The display assembly 200 may include a first display area 220 and a second display area 240, and the first display area 220 and the second display area 240 are fixedly connected, for example, by using a connection structure such as a connection adhesive.
In order to increase the stability of the fixed connection between the first display area 220 and the second display area 240, some embodiments of the present disclosure may form a hole and slot structure on the first display area 220 to receive the second display area 240. For example, the first display area 220 is formed with a receiving hole penetrating the first display area 220 in the thickness direction of the first display area 220, and the second display area 240 can be placed in the receiving hole. The receiving hole may be located at an end position of the first display area 220, or may be located at other positions of the first display area 220, such as a middle position. I.e., the second display area 240 may be enclosed by at least a portion of the first display area 220.
It can be understood that the fixed connection manner between the first display area 220 and the second display area 240 is not limited thereto, such as the width of the first display area 220 is the same as the width of the second display area 240, and the first display area 220 and the second display area 240 are directly spliced to form the display assembly 200.
The size of the first display area 220 is larger than that of the second display area 240, the first display area 220 can be used as a main display portion of the display assembly 200, and the second display area 240 can be used as an auxiliary display portion, or a functional display portion, of the display assembly 200. Such as the light transmittance of the second display region 240 may be set to be greater than that of the first display region 220. Therefore, the light transmittance of the second display area 240 can be greatly improved in the non-display state of the second display area 240, so that when the display assembly 200 is matched with a sensor such as a camera sensor, an ambient light sensor and the like, the optical sensor such as the camera sensor, the ambient light sensor and the like can transmit the second display area 240 to realize signal transmission.
It should be noted that the size relationship between the first display area 220 and the second display area 240 is not limited to this, such as the first display area 220 and the second display area 240 have the same size, and the second display area 240 has a size larger than the first display area 220.
The first display area 220 and the second display area 240 may jointly display a screen to form a display area of the display assembly 200. It should be noted that, in some cases, one of the first display area 220 and the second display area 240 may display a screen. Such as when the display assembly 200 is not manipulated by a user, the second display area 240 may display a screen while the first display area 220 does not display a screen. The off-screen display can be realized, and in the off-screen display state, the display is realized only by the second display area 240, so that compared with the common display of the first display area 220 and the second display area 240, the power consumption can be saved.
Referring to FIG. 2, FIG. 2 is a first schematic view of the display device shown in FIG. 1 taken along a cross-section taken along the line P2-P2. The first display region 220 may include a light emitting layer such as a first light emitting layer 221, an anode layer such as a first anode layer 222, a cathode layer such as a first cathode layer 223, and a circuit layer such as a first circuit layer 224. The first cathode layer 223, the first light emitting layer 221, the first anode layer 222, and the first circuit layer 224 may be sequentially stacked.
The first light emitting layer 221 may include a first electron transport layer, a first organic material layer, and a first hole transport layer, which are sequentially stacked. The first electron transport layer may be disposed to be stacked with the first cathode layer 223, and the first hole transport layer may be disposed to be stacked with the first anode layer 222. The first anode layer 222 and the first cathode layer 223 are energized to drive both electrons in the first electron transport layer and holes in the first hole transport layer toward the first organic material layer, thereby driving the first organic material layer to emit color light signals, such as red, green, and blue light signals.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a layout of a portion of pixels in a display device according to an embodiment of the present disclosure. The first display region 220 may include a plurality of pixels such as a plurality of first pixels 220A, and the plurality of first pixels 220A may include a plurality of first red pixels 2201, a plurality of first green pixels 2202, and a plurality of first blue pixels 2203. One first red pixel 2201, one first green pixel 2202 and one first blue pixel 2203 can form the minimum unit of the display screen of the first display area 220.
Each of the first pixels 220A is formed by a first cathode layer 223, a first light emitting layer 221, and a first anode layer 222. The plurality of first pixels 220A of the embodiment of the present application has a first pixel density (PPI), such as the first pixel is sealed to about 400, such as 400, 403, etc.
The second display region 240 may include a light emitting layer such as a second light emitting layer 241, an anode layer such as a second anode layer 242, a cathode layer such as a second cathode layer 243, a circuit layer such as a second circuit layer 244, and a color filter layer 245. The color filter layer 245, the second cathode layer 243, the second light emitting layer 241, the second anode layer 242, and the second circuit layer 244 may be sequentially stacked.
The second light emitting layer 241 may include a second electron transport layer, a second organic material layer, and a second hole transport layer, which are sequentially stacked. The second electron transport layer may be disposed to be stacked with the second cathode layer 243, and the second hole transport layer may be disposed to be stacked with the second anode layer 242. When the second anode layer 242 and the second cathode layer 243 are powered on, electrons in the second electron transport layer and holes in the second hole transport layer can be driven to move towards the second organic material layer, and then the second organic material layer is driven to emit a white light signal, that is, white light is emitted.
The white light signals emitted from the second light emitting layer 241 may be transmitted to the color filter layer 245, the white light signals emitted from the second light emitting layer 241 may be filtered through the color filter layer 245, and the color filter layer 245 may output color light signals such as red light signals, green light signals, and blue light signals after the white light signals emitted from the second light emitting layer 241 are filtered through the color filter layer 245. Among them, the color filter layer 245 may include a red light signal filtering part, a green light filtering part, and a blue light filtering part. The red light signal filtering section may filter light signals other than the red light signal. The green light filtering part may filter light signals other than the green light signals. The blue light filtering part may filter light signals other than the blue light signal.
It should be noted that, after the color filter layer 245 performs filtering processing on the white light signal emitted by the second light emitting layer 241, the color light signal that can be output is not limited to this, and may also include light signals of other colors. Such as a yellow light signal.
With continued reference to fig. 3, the second display region 240 may include a plurality of pixels such as a plurality of second pixels 220A, and the plurality of second pixels 240A may include a plurality of second red pixels 2401, a plurality of second green pixels 2402 and a plurality of second blue pixels 2403. One second red pixel 2401, one second green pixel 2402 and one second blue pixel 2403 may form a minimum unit of a display screen of the second display region 240.
Each of the second pixels 240A is formed by a second cathode layer 243, a second light emitting layer 241, a second anode layer 242, and a color filter layer 245. The plurality of second pixels 240A of the embodiment of the present application has a second pixel density, such as the second pixel is sealed to be about 400, for example, 400, 403, and so on.
In some embodiments of the present application, the size of the second pixel 240A is smaller than the size of the first pixel 220A. Such as the size of the second red pixel 2401 being smaller than the size of the first red pixel 2201, the size of the second green pixel 2402 being smaller than the size of the first green pixel 2202, and the size of the second blue pixel 2403 being smaller than the size of the first blue pixel 2203. It should be noted that the size of each of the second pixels 240A may be smaller than any of the first pixels 220A.
It should be noted that the size of the first pixel 220A may be understood as the area of the first pixel 220A, or as a cross section along a direction parallel to the first display region 220. The size of the second pixel 240A may be understood as an area of the second pixel 240A or a cross-section along a direction parallel to the second display region 240.
In an actual manufacturing process, the plurality of first pixels 220A may be processed by a plurality of evaporation processes during the forming process. It should be noted that, each time, the evaporation operation can be performed on a single color, the accuracy requirement of the actual operation on the mask plate is higher, and the size of the first pixel 220A is not easily changed in the implementation process. The plurality of second pixels 240A may be processed by a single evaporation process during the forming process, and may be processed by a single planarization process after the evaporation process to remove an overflow portion, so that the size of the pixels may be reduced. Thereby making the size, such as area, of the second pixel 240A smaller than the size, such as area, of the first pixel 220A. Thereby making the light transmittance of the second display region 240 greater than that of the first display region 220. That is, some embodiments of the present application may improve the light transmittance of the second display region 240.
In some embodiments of the present application, the pixel density of the second display area 240 may be substantially the same as the pixel density of the first display area 220. Such as the first display area 220 having a pixel density of 400 and the second display area 240 having a pixel density of 400. For another example, the pixel density of the first display area 220 is 403, and the pixel density of the second display area 240 is 400. Therefore, some embodiments of the present application may further improve the light transmittance of the second display area 240 while maintaining the pixel density of the second display area 240 to be substantially the same as the pixel density of the first display area 220. Therefore, some embodiments of the present disclosure may ensure that the pixel density of the second display area 240 and the pixel density of the first display area 220 have a consistent level, and may maintain the overall display effect of the display assembly 200, and maintain that the display effects of the first display area 220 and the second display area 240 of the display assembly 200 are not significantly different. In some embodiments of the present application, the light transmittance of the second display area 240 can still be improved without reducing the display effect of the second display area 240. The method can be applied to full-screen equipment.
The color filter layer 245 in the embodiment of the application can also attenuate the reflected light signal of the second display area 240, and can function as a polarizer. Therefore, in the second display area 240 of the embodiment of the present application, no polarizer may be additionally disposed, so that the thickness of the second display area 240 may be reduced on the basis of further improving the light transmittance of the second display area 240. Thereby facilitating the thickness uniformity between the first display area 220 and the second display area 240.
In order to ensure the display effect of the first display region 220, the first display region 220 may include a polarization structure.
