Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
Example one
An embodiment of the present invention provides a display unit, and a structure of the display unit, as shown in fig. 1, includes: a light emitting assembly 10, a lens assembly 11 and a diaphragm 12; wherein,
the light emitting assembly 10 is used for outputting a first projected light beam.
In one embodiment, the light emitting assembly 10 is an OLED or LED; taking the light emitting assembly 10 as an example of an OLED, the composition structure of the OLED, as shown in fig. 2, includes a metal cathode 111 and a metal anode 112; between the metal cathode 111 and the metal anode 112, further comprising: an electron injection layer 113, an electron transport layer 114, a light emitting layer 115, a hole transport layer 116, and a hole injection layer 117.
Under the drive of a certain voltage, the light-emitting component 10 transfers electrons from the metal cathode 111 to the light-emitting layer 115 through the electron injection layer 113 and the electron transport layer 114; holes migrate from the metal anode 112 through the hole injection layer 117 and the hole transport layer 116 to the light emitting layer 115; the electrons and the holes meet at the light emitting layer 115 to form excitons, so that light emitting molecules of the light emitting layer 115 are excited, and visible light is emitted in a corresponding direction of the metal anode 112 after radiation relaxation; of course, after the light-emitting molecules of the light-emitting layer 115 are excited, visible light is also emitted in the direction facing the metal cathode 111; the metal cathode 111 reflects the visible light and emits the visible light in the corresponding direction of the metal anode 112.

The diaphragm 12 is provided with a light-passing hole 118, and is used for the first outgoing light beam 14 to exit at the position of the light-passing hole 118, so as to form a visible light beam of the display unit.
In a preferred embodiment, the diaphragm 12 is further configured to absorb an incident light beam from outside the display unit; in particular, this can be achieved by selecting the color of the material from which the diaphragm 12 is made to be black; in this way, the ambient light can be prevented from entering the light emitting assembly 10 as much as possible, so that the problem of high display unit reflectivity caused by the reflection of the ambient light by the metal cathode 111 can be reduced, and the power consumption of the display unit can be reduced.

The diaphragm 12 is provided with a light-passing hole 118, and is used for the first outgoing light beam 14 to exit at the position of the light-passing hole 118, so as to form a visible light beam of the display unit.
In a preferred embodiment, the diaphragm 11 is further configured to absorb an incident light beam from outside the display unit; in particular, this can be achieved by selecting the color of the material from which the diaphragm 12 is made to be black; in this way, the ambient light can be reduced as much as possible from entering the inside of the light emitting element 10, so that the problem of high display unit reflectivity due to reflection of the ambient light can be reduced, and the power consumption of the display unit can be reduced.

in particular, the lens assembly acts on the first projected light beam output by the light-emitting assembly so that the divergence angle of the first projected light beam is reduced, in a preferred embodiment, so that the first projected light beam is focused on the plane of the diaphragm.
When the first projected light beam output by the light-emitting component is divergent light, the lens component comprises a first lens and a second lens; a first plane carrying the first lens is parallel to a second plane carrying the second lens; the light through hole of the diaphragm corresponding to the lens assembly is positioned on the focal plane of the first lens; and a third plane of the light-emitting component corresponding to the lens component is positioned on the focal plane of the second lens, and the third plane is the output surface of the first projection light beam. The first projection light beam output by the light-emitting component forms a first parallel light beam after passing through the first lens, and the first parallel light beam is output to the second lens, then is acted by the second lens and is converged at the focus of the second lens; namely, the first parallel light beams are converged and output at the through light hole of the diaphragm.
And step S103, the first emergent light beam is emergent through the position of the light through hole of the diaphragm corresponding to the lens assembly to form a visible light beam of the display unit.
Here, when ambient light from outside the display unit enters a structure other than the light-passing hole of the diaphragm, the diaphragm absorbs the incident ambient light.
Specifically, the method can be realized by selecting the color of the material for manufacturing the diaphragm to be black; therefore, the ambient light can be reduced to enter the light-emitting assembly as much as possible, the problem of high display unit reflectivity caused by the reflection of the ambient light is reduced, and the power consumption of the display unit is reduced.

step S201, the at least one light-emitting component outputs a light beam;
specifically, the light emitting component is an OLED or an LED; the number of the light-emitting assemblies is one or more, and when the number of the light-emitting assemblies is multiple, the number of the light-emitting assemblies and the number of the diaphragms are the same as the number of the light-emitting assemblies; and, one light emitting component corresponds to one lens component, and one lens component corresponds to one diaphragm.
Step S202, converging the light beams output by the light-emitting component through the converging component to form a first projected light beam;
specifically, the convergence assembly is arranged between the light emitting assembly and the lens assembly, and the convergence assembly is a prism film or a prism sheet; the light beams output by the light emitting component are converged by the converging component, so that the divergence angle of the first projection light beam output by the light emitting component is small, for example, the light beams output by the light emitting component are focused to output the first projection light beam radiated by a point light source or the emergent area of the parallel light beam output by the light emitting component is reduced, so that light rays in the first projection light beam can be projected to the lens component to act, the utilization rate of the light beams output by the light emitting component can be improved, the display brightness of the display unit is improved, and the display power consumption is reduced.
Step S203, the first projection beam is acted by a corresponding lens assembly to form a first emergent beam;
in particular, the lens assembly acts on the first projected light beam output by the light-emitting assembly so that the divergence angle of the first projected light beam is reduced, in a preferred embodiment, so that the first projected light beam is focused on the plane of the diaphragm.
When the first projected light beam output by the light-emitting component is divergent light, the lens component comprises a first lens and a second lens; a first plane carrying the first lens is parallel to a second plane carrying the second lens; the light through hole of the diaphragm corresponding to the lens assembly is positioned on the focal plane of the first lens; and a third plane of the light-emitting component corresponding to the lens component is positioned on the focal plane of the second lens, and the third plane is the output surface of the first projection light beam. The first projection light beam output by the light-emitting component forms a first parallel light beam after passing through the first lens, and the first parallel light beam is output to the second lens, then is acted by the second lens and is converged at the focus of the second lens; namely, the first parallel light beams are converged and output at the through light hole of the diaphragm.
When the first projection light beam output by the light emitting component is parallel light, the lens component comprises a third lens, a light through hole of a diaphragm corresponding to the lens component is located on a focal plane of the third lens, and the first projection light beam is converged at the focal point of the third lens, namely, converged and output at the light through hole of the diaphragm.
And step S204, the first emergent light beam is emergent from the position of the light through hole of the diaphragm corresponding to the lens assembly to form a visible light beam of the display unit.
Here, when ambient light from outside the display unit enters a structure other than the light-passing hole of the diaphragm, the diaphragm absorbs the incident ambient light.
