The display panel 1 is one of organic light emitting diodes, the display panel 1 includes a light emitting surface, the light emitting surface of the display panel 1 can emit light when the display panel is powered on, the brightness of the light emitting surface of the display panel 1 depends on the magnitude of current, the higher the current is, the higher the brightness is, and conversely, the higher the current is, the lower the brightness is.
The display panel 1 may include an ITO (Indium tin oxide) anode, a metal cathode, an electron transport layer, an organic light emitting layer, and a hole transport layer. The metal cathode can be formed by ink-jet printing, organic vapor deposition or vacuum thermal evaporation, and the electron transport layer, the organic light-emitting layer and the hole transport layer are arranged between the semiconductor oxide layer and the metal cathode. In a possible implementation manner, the working principle of the display panel 1 may be: when a direct current voltage of +2V to +10V is applied to the anode, the metal cathode generates electrons, the ITO anode generates holes, the electrons pass through the electron transport layer under the action of an electric field force, and the holes pass through the hole transport layer and meet at the organic light emitting layer. The electrons and holes are negatively and positively charged, respectively, and they attract each other to excite the organic light-emitting layer to emit light. Since the ITO anode is transparent, light emitted from the organic light emitting layer can be seen.
The reflective layer 2 is located on one side of the light-emitting surface of the display panel 1, and the reflective layer 2 covers the display area 11 of the display panel 1. The reflective layer 2 covers the display region 11 of the display panel 1, the reflective layer 2 of the display region 11 of the display panel 1 has a first opening region 21, and the first opening region 21 corresponds to a pixel region of the display panel 1. Specifically, the first opening region 21 may include a plurality of light-transmitting holes arranged in a manner determined according to the transmittance of the pixel region such that light of the display region 11 of the display panel 1 can pass through the first opening region 21. The plurality of light holes can be arranged according to a certain rule, so that the reflecting layer 2 becomes a metal film similar to a net structure, and the reflecting piece can be integrated on any film layer of the display panel 1. The opening ratio m of the first opening region 21 satisfies: m is more than or equal to 8 percent and less than or equal to 20 percent. In this way, since the first opening area 21 of the reflector corresponds to the pixel area of the display panel 1, when the reflective layer 2 covers the display area 11 of the display panel 1, direct display can be performed in the pixel area, and total reflection display can be performed in the non-display area 12, and the aperture ratio m of the first opening area 21 satisfies: m is more than or equal to 8% and less than or equal to 20%, therefore, reflection stratum 2 can not cause the influence to display area 11 of display panel 1 for display area 11 can carry out the light-emitting through first opening district 21, and then can not influence the transmissivity of display area 11, and then improves display panel 1's contrast, improves the formation of image effect, makes user's practical experience obtain improving.

Optionally, the reflective layer 2 is integrated on the encapsulation layer 13 of the display panel 1.
Specifically, the substrate of the display panel 1 may include an IGZO (indium gallium zinc oxide) back plate; an LTPS (Low Temperature Poly-Silicon) backboard, wherein the IGZO backboard is finished by adopting 8-9 Mask process methods and corresponds to a large-size display panel 1 for displaying, such as a display screen of a battery; the LTPS backplane is completed by adopting 9 Mask process methods and corresponds to the small-size display panel 1, such as a display screen with a painted screen. In the embodiment of the present invention, the reflective layer 2 may be formed on the encapsulation layer 13 of the display panel 1 through a metal process such as warm exposure and wet etching, so that the display device may not only display but also function as a mirror.
Optionally, the reflective layer 2 is a metal patterned reflective layer 2, wherein a high refractive index polymer is mixed in the metal patterned reflective layer 2.
Specifically, in a possible implementation manner, the metal patterned reflective layer 2 may be one or more of a molybdenum film layer, an aluminum film layer, a titanium film layer, a molybdenum-aluminum alloy film layer, a titanium-aluminum alloy film layer, a silver film layer, an indium-tin-oxide semiconductor transparent conductive film, and the like, because the film layer has a high reflectivity and is easy to etch, the reflective layer 2 has a high reflectivity, and different first opening regions 21 may be etched according to characteristics of a pixel region of the display panel 1. In another possible implementation, the metal patterned reflective layer 2 is mixed with a high refractive index polymer, which may include at least one of a polymer of an aromatic monomer and a polymer of a brominated aromatic monomer. For example, a high polymer such as poly (pentabromophenyl methacrylate), etc., and this is not particularly limited in the embodiments of the present invention. In specific applications, the high refractive index polymer may be a polymer of monomers with excellent light transparency (light transparency > 95%), good hardness and scratch resistance (hardness > 2H), and the transmittance of the reflective layer 2 may be adjusted by selecting functional monomers of the high refractive index polymer.
It should be noted that the process flow of the display device provided by the present invention is as follows: before the thin film packaging, the IGZO back plate is manufactured by adopting 8-9 Mask process methods when manufacturing a large-size display panel, and the LTPS back plate is manufactured by adopting 9 Mask process methods when manufacturing a small-size display panel. And then, performing thin film packaging on the back plate, and finally, forming the metal patterned reflecting layer 2 by adopting a low-temperature exposure and wet etching metal process, wherein the metal patterned reflecting layer 2 can be directly integrated on the packaging layer 13.
Optionally, the reflective layer 2 covers the non-display area 12 of the display panel 1, wherein the non-display area 12 of the display panel 1 is located at the periphery of the display area 11 of the display panel 1.
Specifically, the non-display region 12 may be formed on the periphery of the display region 11 of the display panel 1, such as two end positions in the length direction and two end positions in the width direction of the display panel, and further, other functional devices may be disposed in the non-display region, so that the display device has more functions.
Optionally, the reflective layer 2 of the non-display area 12 of the display panel 1 has a second opening area 22 thereon, and the electronic element 3 is disposed in the second opening area 22, wherein an opening ratio n of the second opening area satisfies: n is more than 20 percent and less than or equal to 40 percent; as shown in fig. 3, the display device further includes a circuit board assembly 4, the circuit board assembly 4 is located on a side of the backlight surface of the display panel, and the electronic component 3 is electrically connected to the circuit board assembly 4.
The aperture ratio is a ratio between an area of a light-passing portion where a wiring portion or a transistor portion (normally hidden by a black matrix) of each sub-pixel is removed and an area of the entire sub-pixel. The higher the aperture ratio, the higher the light transmittance. In the embodiment of the present application, the aperture ratio of the first opening region 21 is determined according to the light transmittance of the display region 11 of the display panel 1, and the aperture ratio of the second opening region 22 is determined according to the light transmittance of the electronic element 3, in the present application, when the electronic element 3 includes an infrared sensor, the aperture ratio of the first opening region 21 is greater than the aperture ratio of the second opening region 22. Specifically, the aperture ratio m of the first aperture region 21 satisfies: m is more than or equal to 8% and less than or equal to 20%, and the opening rate n of the second opening area 22 satisfies: n is more than 20% and less than or equal to 40%, so that the non-display area 12 can be compatible with the infrared sensor, and the signal generated by the infrared sensor can be emitted through the second open area 22. In addition, the first opening region 21 in the display region 11 and the second opening region 22 in the non-display region 12 may be completed using the same Mask process. The display device further comprises a circuit board assembly 4, the circuit board assembly 4 is located on one side where the backlight surface of the display panel is located, and the circuit board assembly 4 can be a flexible circuit board, so that the circuit board assembly 4 has the advantages of high wiring density, light weight, thin thickness and good bending property, and can be adapted to a complex installation environment in the display area 11 of the display panel. The circuit board assembly 4 is electrically connected with the electronic element 3, so that the circuit board assembly 4 can control the electronic element 3 to execute corresponding operations, different functions are realized, and the functionality of the display module is enhanced.
Optionally, the electronic component 3 may include one or more of a sensing module, a camera module, and a voice recognition module.
Specifically, when the electronic component 3 includes the sensing module, the temperature can be detected by the electronic component 3.

That is when electronic component 3 includes one or more in response module, camera module, the speech recognition module, can make display device's function diversified, improves the experience that the user used display device.
It should be noted that, in the embodiment of the present application, the sensing module may be an infrared sensor. Since the second opening region 22 is provided on the reflective layer 2 of the non-display region 12 of the display panel 1, the opening ratio n of the second opening region satisfies: n is more than 20% and less than or equal to 40%, so that the non-display area 12 can be compatible with an infrared sensor, and the signal transmission of the infrared sensor is convenient.
In addition, in the embodiment of the present application, when the forms of the display panels 1 are different, the positional relationship between the display panels 1 and the reflective layers 2 may also be different, and specifically, there may be the following three ways:
(1) The reflecting layer 2 is connected with the display panel 1 in a sliding mode, and the reflecting layer 2 and the display panel 1 are switched among a plurality of states; in the first state, the first opening area 21 of the reflective layer 2 coincides with the pixel area of the display panel 1; in the second state, the reflective layer 2 slides away from the display area 11 of the display panel 1.
Since the reflective layer 2 is slidably connected to the display panel 1, the emissive layer and the display surface can be switched between a plurality of states during sliding of the reflective layer 2 with respect to the display panel 1, or sliding of the display panel 1 with respect to the reflective layer 2. When in the first state, the first opening region 21 of the reflective layer 2 coincides with the pixel region of the display panel 1, and at this time, the reflective layer 2 may block the pixel region of the display panel 1, so that a user may reflect light through the display device, that is, the user may use the display device as a mirror. When in the second state, the reflective layer 2 slides away from the display area 11 of the display panel 1, and at this time, the display area 11 may display a picture, and a user may display an image or a picture to be displayed through the display device. That is, by providing one display panel 1, providing the reflective layer 2 on the display panel 1, and slidably connecting the reflective layer 2 to the display panel 1, the display device can have a function of displaying images and a function of reflecting light. In addition, only one display panel 1 needs to be arranged, so that the cost can be saved.
(2) As shown in fig. 5, the display device may further include a folder assembly, and the display panel 1 may include a first display panel 14 and a second display panel 15; the first display panel 14 and the second display panel 15 are hinged by a folding assembly, and the reflective layer 2 covers the display area 11 of the first display panel 14.
Since the first display panel 14 and the second display panel 15 are hinged by the folding assembly, the first display panel 14 and the second display panel 15 can be close to or far away from each other by the folding assembly. When the first display panel 14 and the second display panel 15 are close to each other, the display apparatus may be in a folded state. When the first display panel 14 and the second display panel 15 are distant from each other, the display apparatus may be in an unfolded state. Since the reflective layer 2 covers the display area 11 of the first display panel 14, when the display device is in the unfolded state, light can be reflected by the reflective layer 2, that is, the first display panel 14 can be used as a mirror, and an image or a picture can be displayed by the second display panel 15. By providing the folding member between the first display surface and the second display panel 15, the display device can be in different states, and the user's interest in using the display device can also be improved. It should be noted that the reflective layer 2 also covers the non-display area 12 of the first display panel 14, and the aperture ratio of the second opening area 22 in the non-display area 12 is greater than the aperture ratio of the first opening area 21 in the display area 11, so that the non-display area 12 is compatible with the infrared sensor, and the signal generated by the infrared sensor can be emitted through the second opening area 22.
Optionally, the folding assembly may include a first movable arm, a second movable arm, and a rotation shaft; the first movable arm is arranged on the first display panel 14 and the second movable arm is arranged on the second display panel 15, both the first movable arm and the second movable arm being hinged on the rotation shaft.
Since the first movable arm is disposed on the first display panel 14, and the first movable arm is hinged to the rotation shaft, the first movable arm can drive the first display panel 14 to move around the rotation shaft in the process of moving around the rotation shaft. Since the second movable arm is disposed on the second display panel 15 and the second movable arm is hinged to the rotation shaft, the second movable arm can drive the second display panel 15 to move around the rotation shaft in the process that the second movable arm moves around the rotation shaft. Further, when the first and second movable arms are simultaneously moved about the rotation axis, the first and second display panels 14 and 15 may be simultaneously moved about the rotation axis such that the first and second display panels 14 and 15 are close to or away from each other, such that the display device is in a folded state or an unfolded state. That is, by providing the folding assembly as the first movable arm, the second movable arm, and the rotation shaft, it is possible to facilitate the change of the state of the display apparatus.
(3) As shown in fig. 6 to 8, the display device may further include a sliding assembly, and the display panel 1 may include a third display panel 16 and a fourth display panel 17; the third display panel 16 and the fourth display panel 17 are connected by a sliding component in a sliding way, and the reflecting layer 2 covers the display area 11 of the third display panel 16.
Since the third display panel 16 and the fourth display panel 17 are slidably connected by the sliding assembly, the third display panel 16 can slide relative to the fourth display panel 17, so that the third display panel 16 shields the fourth display panel 17, or the third display panel 16 releases the shielding of the fourth display panel 17. When the third display panel 16 blocks the fourth display panel 17, the third display panel 16 and the fourth display panel 17 may be stacked. When the third display panel 16 releases the shielding of the fourth display panel 17, at this time, the third display panel 16 and the fourth display panel 17 may be in an extended state, that is, it may be considered that the third display panel 16 and the fourth display panel 17 are simultaneously located in one plane. Since the reflective layer 2 covers the display region 11 of the third display panel 16, when the third display panel 16 blocks the fourth display panel 17, a user can see the reflective layer 2 and reflect light through the reflective layer 2. When the third display panel 16 releases the shielding of the fourth display panel 17, the user can see the reflective layer 2 and the fourth display panel 17 at the same time, and at this time, the user can reflect light through the reflective layer 2 and display an image or a picture through the fourth display panel 17. That is, by providing the sliding member between the third display panel 16 and the fourth display panel 17 and covering the third display panel 16 with the reflective layer 2, the usage of the display device can be more diversified and the user experience can be improved. Similarly, the reflective layer 2 also covers the non-display area 12 of the third display panel 16, and the aperture ratio of the second opening area 22 in the non-display area 12 is greater than the aperture ratio of the first opening area 21 in the display area 11, so that the non-display area 12 is compatible with the infrared sensor, and a signal generated by the infrared sensor can be emitted through the second opening area 22.
Specifically, the sliding assembly may include a sliding rail and a slider; the slide block is arranged on the third display panel 16, and the slide rail is arranged on the fourth display panel 17; in the case where the third display panel 16 and the fourth display panel 17 are slidably connected by the sliding assembly, the slider slides along the length direction of the slide rail, the length direction of the slide rail coincides with the sliding direction of the third display panel 16, and the sliding direction coincides with the direction indicated by a in fig. 6 and 7.
Because the slider is arranged on the third display panel 16 and the slide rail is arranged on the fourth display panel 17, when the slider slides in the slide rail, the slider can drive the third display panel 16 to slide relative to the fourth display panel 17, so that the third display panel 16 shields the fourth display panel 17, or the third display panel 16 releases shielding of the fourth display panel 17. That is, the sliding assembly is set as the sliding block and the sliding rail, so that the third display panel 16 can slide relative to the fourth display panel 17, and the third display panel 16 can shield or not shield the fourth display panel 17, so that the display device is more diversified in use.
Optionally, the display device may further include a bracket, and the display panel 1 is clipped on the bracket.
When display device includes the support, when display panel 1 joint was on the support, in the in-process of using display device, the support can play the supporting role to display panel 1 for can directly place display device on the plane, later through display panel 1 display image or picture. That is, when the display device includes the stand, the display device can be made convenient to use, increasing the range of use of the display device.
It should be noted that, a card slot may be disposed on the bracket, and the display panel 1 may be clamped in the card slot.
Further, the reflective layer 2 where the second opening region 22 is located is a transflective film; the transflective film faces the light emitting surface of the display panel 1, and the transflective film is used for transmitting incident light.
Specifically, the reflective layer 2 in which the second opening region 22 is located is a transflective film for transmitting incident light, so that the usage requirement of the electronic element 3 requiring light to enter in the second opening region 22 can be satisfied.
Optionally, as shown in fig. 4, the reflective layer 2 further includes a frame 5 extending outside the periphery of the display panel 1.
Specifically, because the reflection stratum 2 still includes and expands in display panel 1 outlying frame 5 outward, like this, in standby state, display area 11 and non-display area 12 all are in the state that can reflect, and then make display area 11 and non-display area 12 be the mirror surface, when display device standby state, can regard as a mirror practicality jointly, and because display area 11 and non-display area 12 are unanimous at standby state's display state, consequently make whole display panel 1 not have obvious frame 5, and then make display device better at standby state's display effect, further promotion user's impression experience.
It should be noted that, in a possible implementation manner, the bezel 5 may include a metal frame, a middle portion of the metal frame is a receiving area, a portion of the reflection layer 2 that extends outside the periphery of the display panel 1 is located in the receiving area, and further, mirror reflection may also be formed in the metal frame, so that the uniformity of the appearance of the display device is higher.
Optionally, in another possible implementation manner, the display panel 1 may be an OLED, an edge area of the display panel 1 is bent towards a direction away from the light exit surface, and the edge area of the display panel 1 is an arc surface.
