[0030] With the increasing development of technology, smart devices are becoming more and more popular, and the public loves smart devices more and more, and the public also has an increasing demand for more portable smart devices.

[0031] Therefore, the display devices of some current smart devices are small in size and narrow in space. For example, in watches, due to space limitations, the gap between the light-emitting element and the light guide plate is too small, and the light emitted by the light-emitting element as a point source cannot be evenly mixed into a surface light source through the light guide plate for emission.

[0032] The present application provides a display device, which may include but is not limited to mobile phones, tablets, laptop computers, desktop computers, terminal machines, interactive displays, digital audio and video devices, Internet of Things devices, etc. Among them, the interactive display may include an interactive whiteboard, a digital advertising interactive screen, a game interactive display, etc., and the Internet of Things device may include smart home devices and smart wearable devices, etc. Among them, the smart wearable device may include a smart watch, etc.

[0033] Please refer to Figures 1-4 , Figure 1 is a schematic structural diagram of a display device according to one or more embodiments; Figure 2 is according to Figure 1Partial enlarged schematic view of the display device shown; Figure 3 is based on Figure 1 Sectional view of the display device shown along the A-A direction; Figure 4 is based on Figure 1 Sectional view of the display device shown along the B-B direction.

[0034] The display device 1 includes a display panel 10, a light-emitting element 20, a light mixing element 30, and a light guide element 40. The light-emitting element 20 is configured to emit an initial light beam 21. The light mixing element 30 is disposed on the optical path of the initial light beam 21. The light mixing element 30 is configured to receive the initial light beam 21 and mix and emit the initial light beam 21. The light guide element 40 is disposed on the light-emitting side of the light mixing element 30. The light guide element 40 is configured to guide the light beam emitted by the light mixing element 30 to the display panel 10.

[0035] The display device 1 can be a common mobile phone, a feature phone, or a smart phone. The smart phone can be a flat-screen phone, a curved-screen phone, a foldable phone, etc. The display device 1 is provided with a display panel 10. The display panel 10 can be disposed at the head, middle, or tail of the display device 1. The display panel 10 can be used for information display of the display device 1. For example, the display panel 10 can serve as the visual information display part of the display device 1. The display panel 10 can also serve as a touch information input part, which is used to facilitate the user to operate the display device 1 by touching the display panel 10. For example, it is used for the display and input requirements during the interface navigation and function switching of the display device 1. The display panel 10 can include, but is not limited to, a liquid crystal display panel 10. The display device 1 can provide a display interface and touch input through the display panel 10 to implement corresponding functions.

[0036] The light-emitting element 20 is used to emit an initial light beam 21. The light-emitting element 20 may include, but is not limited to, an LED, etc. Among them, the LED may include a red LED, a green LED, and a blue LED. The color temperature of the initial light beam 21 can be changed by changing the proportion of the light emitted by the red LED, the green LED, and the blue LED. Exemplarily, by changing the current input to the LED, if it is necessary to increase the color temperature, the proportion of the blue LED light can be increased or the proportion of the red and green LED lights can be decreased. If it is necessary to decrease the color temperature, the proportion of the red and green LED lights can be increased or the proportion of the blue LED light can be decreased. The light-emitting element 20 may be a plurality of point light sources. The light mixing element 30 is disposed on the optical path of the initial light beam 21. After the initial light beam 21 enters the light mixing element 30, it can be reflected, refracted, and scattered multiple times within the light mixing element 30, etc., and exits from the light-emitting side of the light mixing element 30. The light guiding element 40 is disposed on the light-emitting side of the light mixing element 30, and can guide the light beam exiting from the light mixing element 30 to the display panel 10, so that the light beam exiting from the light mixing element 30 provides a surface light source for the display panel 10. Thus, the initial light beam 21 emitted by the light-emitting element 20 is uniformly mixed after being reflected, refracted, and scattered multiple times by the light mixing element 30, and the point light source can be converted into a surface light source, and is guided to the display panel 10 by the light guiding element 40 located on the light-emitting side of the light mixing element 30, which is convenient for the display panel 10 to display an image, thereby reducing the risk that the initial light beam 21 cannot be fully mixed due to the too small space between the light-emitting element 20 and the light guiding element 40, and further, light mixing can be performed in a smaller space, saving space.

[0037] In some embodiments, the light mixing element 30 includes a light-transmitting layer 31 and scattering particles 32, and a plurality of scattering particles 32 are dispersed in the light-transmitting layer 31. The light-transmitting layer 31 is a light-transmitting material that allows the initial light beam 21 to enter and propagate within the light-transmitting layer 31. The material of the light-transmitting layer 31 may include, but is not limited to, polycarbonate, etc. The refractive index of the scattering particles 32 is different from that of the material of the light-transmitting layer 31. After the initial light beam 21 enters the light-transmitting layer 31, since the refractive index of the scattering particles 32 is different from that of the light-transmitting layer 31, the initial light beam 21 will be continuously reflected, refracted, and scattered between the material of the light-transmitting layer 31 and the scattering particles 32, and then uniformly mixed. Exemplarily, the scattering particles 32 may be vacuum holes, the light-emitting element 20 is a blue LED, a red LED, and a green LED, and the blue, red, and green initial light beams 21 emitted by the light-emitting element 20 are continuously reflected, refracted, and scattered in the light-transmitting layer 31 and the scattering particles 32, and then uniformly mixed into white light of different color temperatures.

[0038] In some embodiments, the light mixing element 30 has a first surface 33 and a second surface 34 arranged opposite to each other. The light guiding element 40 is disposed on the first surface 33, and the light emitting element 20 is disposed on the second surface 34. The light transmissive layer 31 may be disposed between the first surface 33 and the second surface 34, and the scattering particles 32 may also be located between the first surface 33 and the second surface 34. The initial light beam 21 enters the light mixing element 30 through the second surface 34, and after being mixed in the light mixing element 30, it enters the light guiding element 40 through the first surface 33. Thus, it is convenient for the initial light beam 21 to be emitted and mixed and then directly enter the light guiding element 40, thereby reducing the gap between the light emitting element 20 and the light guiding element 40, and further saving space.

[0039] Further, the first surface 33 and the second surface 34 are connected by a connecting surface 35. The area of the first surface 33 is larger than the area of the second surface 34. The connecting surface 35 is inclined with respect to the first surface 33 and the second surface 34, and the inclination angle x of the connecting surface 35 is greater than the light emitting angle y of the light emitting element 20. The area of the first surface 33 is larger than the area of the second surface 34 and they are connected by the connecting surface 35. The connecting surface 35 is inclined with respect to the first surface 33 and the second surface 34, and the inclination angle is greater than or equal to the light emitting angle y of the light emitting element 20. Exemplarily, when the light emitting angle y of the light emitting element 20 is 120 degrees, the inclination angle of the connecting surface 35 with respect to the first surface 33 and the second surface 34 can be 120 degrees, 130 degrees, 135 degrees, etc. Thus, all of the initial light beam 21 emitted by the light emitting element 20 can enter the light mixing element 30, reducing the risk of loss of the initial light beam 21 that does not enter the light mixing element 30.

[0040] Optionally, the light mixing element 30 further includes a reflective layer 36. The reflective layer 36 surrounds the light emitting element 20 and covers the second surface 34 and the connecting surface 35. The material of the reflective layer 36 may have a high reflectivity, and may include but is not limited to white ink. The reflective layer 36 surrounds the light emitting element 20 and covers the second surface 34 and the connecting surface 35. When the initial light beam 21 is continuously refracted, reflected and scattered in the light mixing element 30, there may be a risk of exiting through the second surface 34 and the connecting surface 35. Thus, the reflective layer 36 can reflect the light beam about to exit through the second surface 34 and the connecting surface 35 back into the light mixing element 30, so that the mixed light beam exits from the light emitting side of the light mixing element 30, reducing the risk of the light beam exiting through the second surface 34 and the connecting surface 35.

[0041] In some embodiments, the light guiding element 40 includes a reflector 41, a light guide plate 42, and an optical thin film 43. The light guide plate 42 is disposed on the light emitting side of the light mixing element 30. The reflector 41 is disposed on the side of the light guide plate 42 away from the display panel 10. The optical thin film 43 is disposed on the side of the light guide plate 42 close to the display panel 10. The light guide plate 42 is disposed on the light emitting side of the light mixing element 30 and can receive the mixed light beam emitted from the light mixing element 30. The reflector 41 is disposed on the side of the light guide plate 42 away from the display panel 10. The reflector 41 can have a high reflectivity, facilitating reflecting the light beam about to be emitted from the side of the light guide plate 42 away from the display panel 10 back into the light guide plate 42, so that the light guide plate 42 guides the light beam emitted from the light mixing element 30 to the optical thin film 43. The optical thin film 43 can further concentrate and guide the light beam on the light emitting side of the light guide plate 42 to the display panel 10. The optical thin film 43 can cooperate with the light guide plate 42 to make the light beam evenly distributed on the display panel 10, thereby making the displayed image have better brightness uniformity and visual effect. Thus, it is convenient for the light guiding element 40 to better guide the light beam emitted from the light mixing element 30 to the display panel 10.

[0042] In some embodiments, the display device 1 further includes a dimming component 50 disposed around the light guide plate 42. The dimming component 50 can include dimming glass. Exemplarily, the dimming glass includes electrochromic glass, which has adjustable light transmission performance and can change the amount of transmitted light through the control of an external electric field to achieve transparent, semi-transparent, or opaque states. When the periphery of the light guide plate 42 is too dark, the dimming glass turns white to provide supplementary white light and compensate for the over-dark phenomenon at the periphery of the light guide plate 42. When the periphery of the light guide plate 42 is too bright, the dimming glass turns black, thereby absorbing a certain amount of light. Thus, by means of the dimming component 50 disposed around the light guide plate 42, the brightness of the light guide plate 42 can be flexibly balanced, and further the risk of uneven brightness of the display panel 10 caused by uneven light emission of the light guide plate 42 can be reduced.

[0043] Furthermore, the display device 1 further includes a backplane 60. The backplane 60 includes a main body portion 61 and a support portion 62. An accommodation space 611 is formed in the main body portion 61. The display panel 10, the light-emitting element 20, the light guide element 40, and the light mixing element 30 are disposed in the accommodation space 611. The support portion 62 is disposed on the side wall of the accommodation space 611, and the display panel 10 is disposed on the support portion 62. The material of the backplane 60 may include, but is not limited to, metal or plastic, etc. The shape of the backplane 60 may match the shape of the light guide element 40. The main body portion 61 forms the accommodation space 611 to accommodate the display panel 10, the light-emitting element 20, the light guide element 40, and the light mixing element 30. The support portion 62 is disposed on the side wall of the accommodation space 611. Exemplarily, the shape of the light guide plate 42 is circular, the main body portion 61 of the backplane 60 is cylindrical, and the support portion 62 protrudes into the accommodation space 611 relative to the side wall of the accommodation space 611. When observed in a direction perpendicular to the light-emitting side of the light guide plate 42, the support portion 62 may be a circular ring surrounding the side wall of the accommodation space 611. Thus, the backplane 60 can provide structural support and protection for the display panel 10, the light-emitting element 20, the light guide element 40, and the light mixing element 30, and reduce the risk of damage to parts such as the display panel 10 due to factors such as impact.

[0044] In some embodiments, the display device 1 further includes a buffer member 70. The buffer member 70 includes a first buffer portion 71 and a second buffer portion 72. The first buffer portion 71 is located between the support portion 62 and the display panel 10, and the second buffer portion 72 is located between the main body portion 61 and the display panel 10. The buffer member 70 may be elastic, and the material of the buffer member 70 may include, but is not limited to, rubber, etc. The first buffer portion 71 located between the support portion 62 and the display panel 10 can be used to reduce the risk of the display panel 10 being broken due to a collision between the display panel 10 and the support portion 62. The second buffer portion 72 located between the main body portion 61 and the display panel 10 can be used to reduce the risk of the display panel 10 being broken due to a collision between the display panel 10 and the main body portion 61. Thus, the stability of the display panel 10 is further improved, and the risk of damage to the display panel 10 due to factors such as impact is reduced.

[0045] In some embodiments, the display device 1 further includes a packaging glass 80 and a sealant 90. The sealant 90 is disposed on a side of the display panel 10 and the second buffer portion 72 away from the first buffer portion 71, and the packaging glass 80 is located on a side of the sealant 90 away from the display panel 10. The sealant 90 has adhesiveness. The sealant 90 is disposed on a side of the display panel 10 and the second buffer portion 72 away from the first buffer portion 71. Thus, the packaging glass 80 can be bonded to the display panel 10 and the second buffer portion 72 through the sealant 90, so as to cooperate with the backplane 60 to package and protect the display panel 10, the light-emitting element 20, the light mixing element 30, the light guiding element 40, etc., improve the stability of the display panel 10, reduce the risk of damage to the display panel 10, and at the same time, the user can observe the image displayed on the display panel 10 through the packaging glass 80.

[0046] In summary, the display device 1 of the present application includes a display panel 10, a light-emitting element 20, a light mixing element 30, and a light guiding element 40. The light-emitting element 20 is configured to emit an initial light beam 21. The light mixing element 30 is disposed on the optical path of the initial light beam 21. The light mixing element 30 is configured to receive the initial light beam 21 and mix and emit the initial light beam 21. The light guiding element 40 is disposed on the light-emitting side of the light mixing element 30. The light guiding element 40 is configured to guide the light beam emitted from the light mixing element 30 to the display panel 10. Through the above-described embodiments, the initial light beam 21 emitted by the light-emitting element 20 can be mixed and emitted by the light mixing element 30, and the light guiding element 40 can receive the light beam emitted from the light mixing element 30 and guide it to the display panel 10. Thus, the light mixing is performed between the light-emitting element 20 and the light guiding element 40 through the light mixing element 30, reducing the gap, thereby saving space and facilitating the mixing of point light sources into surface light sources in a narrow space. Compared with other display devices, the display device 1 provided by the present application can perform light mixing in a smaller space, saving space.
