Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a display screen according to a first embodiment of the present invention, the display screen includes:
a calibration mesh 1, a plurality of LED units 2, and a substrate 3;
a substrate 3 for mounting a plurality of LED units 2;
the correction net 1 corrects the arrangement positions of the plurality of LED units 2 mounted on the substrate 3 so that the pitches of the plurality of LED units after correction are the same.
The substrate 3 in this embodiment is a Copper Clad Laminate, and in manufacturing the single-sided and double-sided printed boards, hole machining, chemical Copper plating, electrolytic Copper plating, etching and other machining are selectively performed on a substrate material-Copper Clad Laminate (CCL) to obtain a desired circuit pattern; the other type of multilayer printed board is also manufactured by taking an inner core thin copper clad laminate as a base, and alternately laminating and bonding a conductive pattern layer and a prepreg (Pregpr' eg) together at one time to form interconnection among more than 3 conductive pattern layers; it has the functions of conducting, insulating and supporting; the performance, quality, workability in manufacturing, manufacturing cost, manufacturing level, and the like of the printed board greatly depend on the substrate material. It is understood that the substrate 3 may be made of PET (thermoplastic polyester), PI (Polyimide), or other materials.
It should be clear that the substrate 3 in this embodiment is used for mounting a plurality of LED units 2, wherein a plurality means two or more; in practical application, the number of the LED units 2 mounted on the substrate 3 can be flexibly adjusted according to specific application scenes; it should be noted that the LED unit 2 mounted on the substrate 3 is an already packaged LED unit 2.
The LED unit 2 in this embodiment is made of a compound containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), or the like, and radiates visible light when electrons and holes recombine, and thus can be used to make a light emitting diode; wherein the gallium arsenide diode emits red light, the gallium phosphide diode emits green light, the silicon carbide diode emits yellow light, and the gallium nitride diode emits blue light; organic light emitting diodes OLED and inorganic light emitting diodes LED are classified by their chemical properties. It can be understood that the LED unit 2 is a commonly used light emitting device, emits light by energy released by recombination of electrons and holes, and is widely used in the field of illumination; the LED unit 2 can efficiently convert electric energy into light energy, and has wide applications in modern society, such as illumination, flat panel display, medical devices, and the like.
In some examples, referring to fig. 3-1, a plurality of LED units 2 may be mounted on a substrate 3 in only a lateral arrangement.
In some examples, as shown in fig. 3-2, a plurality of LED units 2 may be mounted on the substrate 3 in a longitudinal arrangement only.
In some examples, as shown in fig. 3-3, a plurality of LED units 2 may be mounted on a substrate 3 in a lateral and longitudinal arrangement.
In some examples, as shown in fig. 3-4, a plurality of LED units 2 may be mounted on the substrate 3 in a laterally and longitudinally staggered arrangement with respect to each other.
It should be noted that, in practical applications, the arrangement of the plurality of LED units 2 mounted on the substrate 3 may be adjusted according to specific application scenarios.
The setting position of the correction net 1 in this embodiment is shown as a dotted line in fig. 2, that is, the gap position between the LED units 2 may be set in a part or all of the gap position, or a part or all of the gap position beyond the gap position, and in practical application, the setting position may be adjusted according to a specific application scenario.
The manufacturing material of the correction net 1 in this embodiment may be the same as the material of the packaged LED unit 2, wherein the material of the packaged LED unit 2 may be LED lens filled silica gel, LED module mold top packaging glue, LED cofferdam glue, LED phosphor glue, and the like. Because the correction net 1 is made of the same material as the packaged LED unit 2, the refractive index of light emitted by the LED is higher, the light path is more divergent, and the display effect of the display screen can be improved to a certain extent. Of course, in some examples, the calibration mesh 1 may be made of a material similar to that of the packaged LED unit 2, or a material different from that of the packaged LED unit 2; in practical application, the manufacturing material of the correction net 1 can be flexibly adjusted according to specific application scenes.
It should be clear that the calibration net 3 in the present embodiment is used to calibrate the arrangement positions of the LED units 2 mounted on the substrate 3, so that the corrected intervals between the LED units 2 are the same, i.e. the LED units 2 are arranged in order; therefore, the phenomenon of poor display effect caused by the fact that the LED units 2 are not arranged uniformly in the related art can be avoided, and the display effect of the display screen is improved.
In some examples, please refer to fig. 4-1, in order to correct the arrangement position of the plurality of LED units 2 mounted on the substrate in the transverse arrangement by using the correction net 3, the corrected intervals between the plurality of LED units 2 in the transverse arrangement are the same.
In some examples, please refer to fig. 4-2, in order to correct the arrangement position of the plurality of LED units 2 mounted on the substrate in the longitudinal arrangement by using the correction net 3, the corrected intervals between the plurality of LED units 2 in the longitudinal arrangement are the same.
In some examples, please refer to fig. 4-3, in order to correct the arrangement position of the plurality of LED units 2 arranged on the substrate in the transverse and longitudinal directions by using the correction net 3, the corrected intervals between the plurality of LED units 2 arranged in the transverse and longitudinal directions are the same.
In some examples, please refer to fig. 4-4, in order to correct the arrangement position of the plurality of LED units 2 mounted on the substrate in the lateral and longitudinal misalignment arrangement by using the correction net 3, the corrected intervals between the plurality of LED units 2 in the lateral and longitudinal misalignment arrangement are the same.
The correction net 1 in this embodiment may include a supporting net 11 and a correction component 12 disposed on the supporting net, wherein the supporting net 11 is used for supporting a plurality of LED units 2 mounted on the substrate 1, and the correction component 12 is a component that really plays a role of correction, i.e., light emitted from the side edge of the encapsulated LED unit enters the correction component 12, and then the light is refracted by the correction component 12, so as to increase the refraction angle of light emitted from the LED unit 2, and to implement the compensation of the side viewing angle color cast.
It should be understood that if the plurality of LED units 2 mounted on the substrate 3 are arranged in the lateral direction and the support net 11 is a horizontal bar support net, each of the correction members 12 is disposed on the horizontal bar support net corresponding to the pitch position of the plurality of LED units 2; and/or, if the plurality of LED units 2 mounted on the substrate 3 are arranged in the longitudinal direction and the support net 11 is a vertical bar support net, each of the correction members 12 is provided on the vertical bar support net corresponding to the pitch position of the plurality of LED units 2.
For better understanding, please refer to fig. 5, which is an example of a horizontal bar support net and a vertical bar support net, each blank area is a mounting position of a plurality of LED units, wherein the support net 11 and the calibration component 12 may be an integrated structure, which facilitates simultaneous calibration of a plurality of LED units 2, reduces calibration time, and reduces workload of related calibration personnel. Of course, in some examples, the supporting net 11 and the calibration component 12 may not be integrally formed, which can reduce the difficulty of manufacturing the calibration net 1, reduce the time length of manufacturing the calibration net 1, and reduce the workload of related calibration net manufacturers.
It should be clear that, in general, the pitch positions of the plurality of LED units 2 are generally small; therefore, the correction component 12 in this embodiment may be configured to be an inverted triangle, which is more convenient to realize the correction of the plurality of LED units 2, and avoids the problem of difficult correction caused by the small distance between the plurality of LED units 2. As shown in fig. 6-1, the correcting member 12 is provided in an inverted triangular shape in a sectional view in a position of a gap between the plurality of LED units 2; meanwhile, please refer to fig. 6-2, which is a schematic diagram of light paths after light emitted from the side of the packaged LED unit 2 enters the inverse triangular correction component 12 and is further refracted by the inverse triangular correction component 12, wherein the light paths on the left and right sides are the same, thereby avoiding color cast at different viewing angles.
In some examples, the refractive index of the correction component 12 may be 1.2-1.8, and it can be understood that the higher the refractive index of the correction component 12 is, the light emitted from the side edge of the packaged LED unit 2 enters the correction component 12, and is further refracted by the correction component 12 in the shape of an inverted triangle, and then the corresponding light path is more divergent, so that the display effect of the display screen is improved; in practical applications, the refractive index of the correcting element 12 can be flexibly adjusted according to specific application scenarios.
In some examples, the apex angle of the inverted triangle shape of the correcting member 12 may be 20 ° to 60 °, wherein in fig. 6 the apex angle of the inverted triangle shape is 25 °; in practical application, the vertex angle of the inverse triangle of the correction component 12 can be flexibly adjusted according to a specific application scene.
It should be noted that the shape of the correction component 12 may also be other shapes, such as an ellipse, a rectangle, etc., and in practical applications, the shape of the correction component 12 may be adjusted according to specific application scenarios.
In this embodiment, the display screen includes a correction screen, a plurality of LED units, and a substrate, where the substrate is used to mount the plurality of LED units, and the correction screen is used to correct the arrangement positions of the plurality of LED units mounted on the substrate, so that the corrected intervals between the plurality of LED units are the same; the problem of the display effect of display screen among the correlation technique is poor is solved.
That is, in the embodiment, the arrangement positions of the plurality of LED units mounted on the substrate are corrected by the correction net, so that the plurality of LED units are arranged neatly, a series of phenomena such as color mixing, saw teeth, granular sensation and the like caused by the uneven arrangement of the plurality of LED units in the related art are avoided, and the display effect of the display screen is improved; and the correction net adopts the correction part in the shape of the inverted triangle, so that the correction difficulty that the distance positions of the LED units are slightly small and difficult to correct is reduced, the phenomenon of color cast of different side visual angles is avoided, and the display effect of the display screen is further improved.
