Description
Technical field
The present invention relates to a kind of black and white to highlight amber backing structure, belongs to display technology field.
Background technology
Amber backlight, which is usually used in air-conditioning remote control, washing machine, household appliances and indoor and outdoor, the equipment of particular/special requirement.
High brightness designs, and normal design method is increase LED, and in the market high brightness lamp is rarer, increases LED quantity, exists
The problem of two aspects, first, cost aggravates, in the market high-brightness LED lamp is on the high side；Second, the limitation of structure.It is amber
The different color screens of backlight membrane material collocation, color screen can be according to glass self-views, and the angle adjusted between bright enhancement film and diffusion is arranged in pairs or groups,
Angle collocation can also suitably lift brightness.Amber highlighted module often uses high diffusion barrier, DBEF, ESR reflector plate thoroughly,
It is costly, and the high easy folding line of diffusion barrier thoroughly, backlight foreign matter, the shortcomings of little particle is high-visible.Simultaneously because LED
Light efficiency is relatively low, can produce substantial amounts of heat during work, if not solving heat dissipation problem, can cause LED luminosity decay and
The shortening of service life.In order to suppress the briliancy of heat influence backlight module caused by LED and colourity it is necessary to be dissipated to LED
Thermal design, radiated from aluminum-based copper-clad plate, it is possible to achieve the highlighted design of amber backlight.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of black and white to highlight amber backing structure, it is used
A kind of new aluminum-based copper-clad plate material, can solve the LED heat dissipation problem for highlighting amber backing structure, there is provided the stabilization of brightness
Property.
The purpose of the present invention is achieved through the following technical solutions：
A kind of black and white highlights amber backing structure, including：
LED light source, it is amber LED light bar；
Aluminum-based copper-clad plate, the LED light source are arranged on the one side or the multi-lateral of the aluminum-based copper-clad plate；
The bottom of the aluminum-based copper-clad plate is provided with FPC plates, be sequentially provided with above the aluminum-based copper-clad plate white emission piece,
Light guide plate, diffusion barrier.
Further, the aluminum-based copper-clad plate is as LED backlight plate.
Further, the aluminum-based copper-clad plate is covered with insulating materials, copper foil paving using aluminium sheet as substrate above the aluminium sheet
Above insulating materials.
Further, the upper surface of the copper foil scribbles Impedance Membrane.
Further, the LED light source on the aluminum-based copper-clad plate is provided with backlight interface.
Further, backing structure is superimposed as by the diffusion barrier to FPC plates successively, the backing structure periphery is provided with glue
Framework.
Further, the top surface of the backing structure is provided with black and white double faced adhesive tape.
Beneficial effects of the present invention are：
The present invention fully solves LED heat dissipation problem, ensure that LED normal table work.LED is in the course of the work
A large amount of heat energy can be sent so that own temperature raises, and can not such as radiate in time, it is easy to cause the damage of device.LED bottom
There will be metal conducting strip, it can conduct heat well with LED chip, only need the heat on metal conducting strip to shed.
Existing backing structure, all it is that metal conducting strip is arranged on FPC plates, and common FPC plate main materials are FR-4, it is led
Hot property is bad, it is impossible to reaches requirement.The present invention is had from heat conduction and the more preferable aluminum-based copper-clad plate of toughness, aluminum-based copper-clad plate
High-cooling property, high-fire resistance, electromagnetic wave shielding, high mechanical strength, processing characteristics are excellent.Carried on the back using aluminum-based copper-clad plate as LED
Tabula rasa, aluminum-based copper-clad plate are using aluminium sheet as substrate, then cover last layer heat-conducting insulation material, and copper foil is laid on above insulating materials,
Finally Impedance Membrane is coated on the surface of copper foil to reach the purpose of insulation.Present invention is designed such that the brightness of amber backlight is not
Decay occurs, permanent retention highlights phenomenon.
Brief description of the drawings
Fig. 1 is traditional highlighted amber backing structure；
Fig. 2 is that black and white of the present invention highlights amber backing structure；
Wherein, 1- black and white double faced adhesive tapes, 2- diffusion barriers, 3- light guide plates, 4- white reflective pieces, the amber LEDs of 5-, 6- aluminium bases
