In addition, the display device 100 of the embodiment of the present application can also be used as a display screen of an electronic device for displaying patterns, characters, and the like.

Referring to fig. 1 and fig. 2, an embodiment of the present application provides a display device 100, which includes a display layer 10 and a plurality of light emitting units 30, where the display layer 10 includes a plurality of display units 11; a plurality of light emitting cells 30 disposed around the periphery of the display layer 10, the plurality of light emitting cells 30 for emitting light signals to the display layer 10; when the plurality of display units 11 are loaded with the control signal and at least a part of the light emitting units 30 emit light signals to the display layer 10, at least a part of the light emitting units 30 cooperate with the plurality of display units 11 to perform display.

"plurality" means greater than or equal to 2.

The form of the display device 100 of the present application may be, but is not limited to, a film, a sheet, a plate, and the like, and it is to be understood that the form of the display device 100 does not limit the display device 100 provided in the present application.

In some embodiments, the plurality of display units 11 of the display layer 10 are arranged in an array. Each display unit 11 can be independently controlled to perform display in cooperation with the light emitting unit 30.

The light emitting units 30 are used for emitting light signals to the display layer 10, and it can be understood that the light emitting surfaces of the light emitting units 30 are disposed towards the display layer 10 to emit the light signals towards the display layer 10. It can be understood that the light emitting surfaces of the light emitting units 30 face the side surface of the display layer 10, so that the light signals emitted from the light emitting units 30 enter the display layer 10 from the side surface of the display layer 10. "side of the display layer 10" refers to a surface that is connected to the display surface of the display layer 10 and is disposed around the outer periphery of the display surface. In one embodiment, the light signal emitted from the light emitting unit 30 is parallel to the extending direction of the display layer 10. In other embodiments, the light signal emitted from the light emitting unit 30 may also be at a predetermined angle with respect to the display layer 10, and should not be construed as a limitation to the display device 100 of the embodiment.

Alternatively, the light signal emitted from the light emitting unit 30 may be a light signal generated by the light emitting unit 30 itself emitting light, or may also be a light signal emitted from another light emitting device and transmitted to the display layer 10 by the light emitting unit 30.

The plurality of light emitting units 30 are disposed around the periphery of the display layer 10, and the plurality of light emitting units 30 may be disposed closely to the outer periphery of the display layer 10, or the plurality of light emitting units 30 may be disposed at intervals around the periphery of the display layer 10. Alternatively, the plurality of light emitting cells 30 are uniformly or equally spaced around the periphery of the display layer 10.

Alternatively, the color of the light signal may include, but is not limited to, including at least one of red, green, blue, yellow, white, black, orange, cyan, violet, pink, gray, and the like. "at least one" means greater than or equal to one. Alternatively, the optical signal may be, but is not limited to, a laser.

Alternatively, the control signal may be, but is not limited to, a voltage signal, a current signal, an electric field signal, an electrostatic force, a charge signal, and the like. In the following embodiments of the present application, the voltage signal is taken as an example for detailed description, and should not be construed as limiting the display device 100 of the present application.

At least some of the light emitting cells 30 emit light signals toward the display layer 10, and it is understood that a plurality of light emitting cells 30 may emit light signals toward the display layer 10 at the same time when displaying; it is also possible that a part of the light emitting cells 30 emit light signals toward the display layer 10 and another part of the light emitting cells 30 stops operating, in other words, a part of the light emitting cells 30 operates and another part of the light emitting cells 30 does not operate. Therefore, the light signals emitted by the light emitting units 30 at different positions can be controlled to match the control signals loaded by the plurality of display units 11, so as to control the content displayed by the display device 100.

The colors of the light signals emitted from the plurality of light emitting units 30 may be the same or different. When the light signals emitted by the plurality of light emitting units 30 are different in color, the light signals emitted by the light emitting units 30 of different colors can be controlled, so that the color of the content displayed by the display device 100 can be controlled, and the display of the content such as colored characters or patterns can be realized.

In some embodiments, when the plurality of display units 11 are loaded with the control signal and at least a portion of the light emitting units 30 emit the light signal to the display layer 10, at least a portion of the plurality of display units 11 reflects the light signal to expose a trace of the reflected light signal on the display layer 10, thereby implementing the display of the display device 100. Through the reflection principle of light, reflect the light signal that gets into display layer 10, the orbit that the light signal passed through can reveal luminous pattern on display layer 10, through the design to the light signal orbit, can realize the design to showing pattern on display layer 10, makes display device 100's structure stack more simple like this, and thickness can be done thinly, when being applied to electronic equipment, can be better satisfy the requirement that electronic equipment is frivolous.

It should be noted that, during displaying, the control signal may control a part of the display units 11 to participate in the reflection of the light signal, and another part of the display units 11 does not participate in the reflection of the light signal; in some cases, the control signal may also control all display elements 11 to participate in the reflection of the light signal. It is thus possible to design a pattern displayed by the display device 100 by controlling the position at which the light signal is incident, the color of the light signal, the position of the display unit 11 participating in reflection, and the like, and to actively control the display of the light-emitting pattern according to the preference of the user, and to display the pattern even in a dark environment.

The display device 100 of the embodiment of the application includes a display layer 10 and a light-emitting unit 30, the display layer 10 includes a plurality of display units 11, the light-emitting unit 30 is disposed at the periphery of the display layer 10 and is configured to emit a light signal to the display layer 10, when the plurality of display units 11 load a control signal and at least a part of the light-emitting units 30 emit the light signal to the display layer 10, at least a part of the light-emitting units 30 is matched with the plurality of display units 11 to control a path of the light signal in the display layer 10, and a corresponding trace line is displayed on a path through which the light signal passes, so that the light-emitting and display functions are realized. By controlling the light emitting units 30 at different positions to emit light signals and the colors of the light emitting signals of the light emitting units 30 and matching the display unit 11, dynamic display effects of various colored patterns can be realized, and when the light emitting units are applied to electronic equipment shell assemblies, aesthetic fatigue of users can be reduced, and the appearance expressive force of electronic equipment is improved. In addition, the display screen can also be used as a display screen of the electronic equipment.

Referring to fig. 2 again, in some embodiments, the display unit 11 includes a first conductive member 111 and a second conductive member 113 disposed opposite to each other and spaced apart from each other; the display unit 11 further includes a reflective element 112, the reflective element 112 is configured to reflect the optical signal, the reflective element 112 is disposed between the first conductive element 111 and the second conductive element 113, and the reflective element 112 is movable in a stacking direction of the first conductive element 111 and the second conductive element 113; the second conductive member 113 is disposed closer to the plurality of light emitting units 30 than the first conductive member 111, and when the first conductive member 111 and the second conductive member 113 are applied with the control signal, at least a part of the reflective member 112 is close to the second conductive member 113 to reflect the light signal, so as to realize the display of the display device 100. When the first conductive member 111 and the second conductive member 113 are loaded with the control signal, at least a part of the reflective member 112 moves toward the second conductive member 113 to be close to the second conductive member 113, and after the optical signal is incident on the display layer 10, the reflective member 112 close to the second conductive member 113 reflects the optical signal so that the optical signal passes along a predetermined route to expose a track of the optical signal on the display layer 10, thereby implementing the display function.

It should be noted that, when the display device 100 is horizontally placed and the second conductive member 113 is located above the first conductive member 111 (as shown in the orientation of fig. 2), if the display unit 11 is in the off state, the reflective member 112 moves close to the first conductive member 111 under the action of gravity. At this time, if the light emitting unit 30 is turned on to emit light signals to the display layer 10, the light signals directly penetrate the entire display layer 10, and a bright line appears on the display layer 10 without any reflection phenomenon. In other embodiments, when the display device 100 is horizontally disposed and the first conductive member 111 is located above the second conductive member 113, if the display unit 11 is in the off state, the reflective member 112 moves close to the second conductive member 113 under the action of gravity. At this time, if the light emitting unit 30 is turned on to emit a light signal to the display layer 10, the light signal is continuously reflected by the reflective member 112, and a pattern composed of a path through which the light passes is displayed on the display layer 10.

It should be noted that the reflective element 112 described herein is close to the second conductive element 113, which means that the reflective element 112 is disposed closer to the second conductive element 113 than the first conductive element 111. The reflective member 112 described herein is located close to the first conductive member 111, which means that the reflective member 112 is located closer to the first conductive member 111 than the second conductive member 113.

In some embodiments, when one part of the reflective member 112 is close to the second conductive member 113 and the other part of the reflective member 112 is close to the first conductive member 111, the control signal controls one part of the reflective member 112 to move towards the second conductive member 113 and the other part of the reflective member 112 to move towards the first conductive member 111. In other embodiments, all of the reflective elements 112 are close to the second conductive element 113, and the control signal controls the reflective elements 112 to move toward the second conductive element 113.

Referring to fig. 3, in some embodiments, the plurality of display units 11 include a first partial display unit 115 and a second partial display unit 117, when the first partial display unit 115 loads the first control signal and the second partial display unit 117 loads the second control signal, the reflective element 112 of the first partial display unit 115 is close to the first conductive element 111, the reflective element 112 of the second partial display unit 117 is close to the second conductive element 113, and the reflective element 112 of the second partial display unit 117 reflects the light signal to realize the display of the display device 100; the control signal comprises a first control signal and a second control signal. When the first partial display unit 115 loads the first control signal and the second partial display unit 117 loads the second control signal, the first control signal controls the reflective member 112 of the first partial display unit 115 to move toward the first conductive member 111, the second control signal controls the reflective member 112 of the second partial display unit 117 to move toward the second conductive member 113, and since the light emitting unit 30 is disposed closer to the second conductive member 113 than the first conductive member 111, according to the linear propagation of light and the reflection of light, the light signal emitted from the light emitting unit 30 is incident to the reflective member 112 of the second partial display unit 117 and is reflected by the reflective member 112 of the second partial display unit 117 along a predetermined trajectory, so as to achieve the display of the predetermined pattern.

In one embodiment, the plurality of reflective elements 112 have polarities such that when the first portion of the display unit 115 is loaded with the first control signal and the second portion of the display unit 117 is loaded with the second control signal, the first control signal controls the reflective element 112 of the first portion of the display unit 115 to be close to the first conductive element 111, the second control signal controls the reflective element 112 of the second portion of the display unit 117 to be close to the second conductive element 113, and the reflective element 112 of the second portion of the display unit 117 reflects the light signal to realize the display of the display device 100; the direction of the electric field generated by the first control signal is opposite to that of the electric field generated by the second control signal. In other words, the plurality of reflective elements 112 have a polarity, the first control signal is a first voltage, the first voltage generates a first electric field, the second control signal is a second voltage, the second voltage generates a second electric field, when the first partial display unit 115 loads the first voltage and the second partial display unit 117 loads the second voltage, the first electric field controls the reflective element 112 of the first partial display unit 115 to move towards the first conductive element 111, the second electric field controls the reflective element 112 of the second partial display unit 117 to move towards the second conductive element 113, and the reflective element 112 of the second partial display unit 117 reflects the light signal to realize the display of the display device 100; wherein the first electric field and the second electric field are opposite in direction. Therefore, the displayed pattern can be adjusted by controlling the direction of the electric field loaded on the display unit 11 and the position of the light emitting signal of the light emitting unit 30, and the control method is simple and convenient and has low preparation cost.

Optionally, the plurality of reflectors 112 have a polarity, which may be a positive polarity for the reflectors 112 or a negative polarity for the reflectors 112. In one embodiment, the reflective element 112 has a polarity that can positively charge the reflective element 112. In another embodiment, the reflector 112 has a polarity that can negatively charge the reflector 112.

As shown in fig. 3, in an embodiment, the reflective element 112 is negatively charged, and when the first conductive element 111 of the first partial display unit 115 is applied with a positive voltage, the second conductive element 113 of the first partial display unit 115 is applied with a negative voltage as the first control signal, the first conductive element 111 of the second partial display unit 117 is applied with a negative voltage, and the second conductive element 113 of the second partial display unit 117 is applied with a positive voltage as the second control signal, an electric field generated by the first control signal causes the reflective element 112 of the first partial display unit 115 to be subjected to an electrostatic force toward the first conductive element 111, so that the reflective element 112 of the first partial display unit 115 moves toward the first conductive element 111 and approaches the first conductive element 111; the electric field generated by the second control signal causes the reflective element 112 of the second partial display unit 117 to be subjected to an electrostatic force toward the second conductive element 113, thereby moving the reflective element 112 of the second partial display unit 117 toward the second conductive element 113 and approaching the second conductive element 113.

Referring to fig. 4, in another embodiment, the reflective element 112 has a positive charge, when the first conductive element 111 of the first display unit 115 is loaded with a negative voltage, the second conductive element 113 of the first display unit 115 is loaded with a positive voltage as the first control signal, the first conductive element 111 of the second display unit 117 is loaded with a positive voltage, and the second conductive element 113 of the second display unit 117 is loaded with a negative voltage as the second control signal, the reflective element 112 of the first display unit 115 is subjected to an electrostatic force toward the first conductive element 111 by an electric field generated by the first control signal, so that the reflective element 112 of the first display unit 115 moves toward the first conductive element 111 and approaches the first conductive element 111; the electric field generated by the second control signal causes the reflective element 112 of the second partial display unit 117 to be subjected to an electrostatic force toward the second conductive element 113, thereby moving the reflective element 112 of the second partial display unit 117 toward the second conductive element 113 and approaching the second conductive element 113.

Referring to fig. 5, in some embodiments, the display layer 10 has a plurality of display portions 101, each display portion 101 includes a plurality of adjacent display units 11, and the reflection directions of the light signals by the reflection members 112 of the same display portion 101 are different from each other. In this way, the light signals can be reflected by controlling different reflectors 112 on the display portion 101, so that the light signals incident on the display portion 101 at the same angle can be reflected to different directions, the light signal path can be changed, and the content of characters, patterns and the like displayed on the display device 100 can be changed.

Alternatively, a plurality of display portions 101 are arranged in an array.

Each display portion 101 includes a plurality of adjacent display units 11, and each display portion 101 may include 2, 3, 4, 5, 6, 7, 8, and so on display units 11, and the greater the number of reflection directions of the light signal by the reflection member 112 of the same display portion 101, the more precisely the path of the light signal may be controlled, so that a finer pattern display may be realized. When the number of the reflection directions of the light signals by the reflection member 112 of the same display portion 101 reaches a certain value, the light signals can be reflected to any angle, so that any pattern can be displayed. In the embodiment of fig. 5, each display section 101 includes four display units 11.

In some embodiments, the reflective members 112 have reflective surfaces 1121, the reflective surfaces 1121 are used for reflecting optical signals, the reflective surfaces 1121 of each reflective member 112 of the same display portion 101 are oriented differently, and the reflective surfaces 1121 extend along a direction perpendicular to the display layer 10.

Optionally, the reflection surface 1121 is a plane, in other words, the reflection surface 1121 is a mirror surface. In an embodiment, the reflective surface 1121 has a total reflection function, so as to better reflect the light signal, thereby better avoiding the loss of light, and making the pattern displayed by the display layer 10 brighter and clearer.

In one embodiment, each display portion 101 has 4 display units 11, and the orientations of the reflective surfaces 1121 of the reflective members 112 of the 4 display units 11 are different from each other. For example, in the embodiment of fig. 5, the angles between the reflection surfaces 1121 of the reflection members 112 of 4 display units 11 and the extending direction (as shown by the arrow B in fig. 5) of the display layer 10 are 0 °, 45 °, 90 °, 135 °, and the like, respectively. When the number of the display units 11 per display portion 101 is more, the reflection surfaces 1121 of the same display portion 101 may have more directions. The more the directions of the reflection surfaces 1121 of the same display section 101 are, the more precisely the path of the optical signal can be controlled, so that a finer pattern can be displayed. When the number of the reflection directions of the reflection surfaces 1121 of the same display portion 101 reaches a certain value, it is possible to reflect an optical signal to an arbitrary angle, thereby realizing display of an arbitrary pattern.
