Abstract
The utility model provides a kind of outdoor LCD display, it is characterized in that, fitted on the display screen panel permeability improvement device, the permeability improvement device is fitted AR glass, adiabatic gum and sensor on display screen panel successively, heat abstractor is installed in the display screen left and right sides, and the heat abstractor is formed by connecting by some metal fins on the outside of display screen and the fin on the inside of display screen.The beneficial effect for implementing the technical solution of the utility model is the characteristics of being separated with anti-reflection heat-insulated, thermoelectricity.
Description
Technical field
The utility model is related to a kind of outdoor display screen, refers in particular to a kind of dynamic backlight open air LCD display heat conduction dress
Put.
Background technology
In the prior art, outdoor display screen technology, can simultaneously play more ad contents, and ad content is changed every time
When only need to change computer on video pictures, the video information on computer is sent on display screen.Meet outdoor rolling
The dynamic requirement for playing advertisement, substantially round-the-clock uninterrupted broadcasting, under such pattern, particularly sun-drenched open air,
Need LCD display there is brightness higher, it is necessary to bigger electric current drives, so the display screen heating problem of open air, if not
Handle well, the life-span of display screen can be badly influenced, heat dissipation problem is a problem, and most common method is dissipated with natural wind
Heat, such scheme needs louvre, such as runs into strong wind and heavy rain weather, and rainwater is easily flowed into from louvre and caused inside display screen
Short circuit.
The content of the invention
In consideration of it, a kind of outdoor LCD display that the utility model is provided, separates with anti-reflection heat-insulated, thermoelectricity, family is solved
The light transmission and heat dispersion of outer LCD display, are achieved through the following technical solutions.
Outdoor LCD display, permeability improvement device of being fitted on the display screen panel, the permeability improvement device is successively in display panel
Heat abstractor is installed in laminating AR glass, adiabatic gum and sensor on plate, the display screen left and right sides, and the heat abstractor is by positioned at aobvious
Some metal fins on the outside of display screen and the fin on the inside of display screen are formed by connecting.
LCD display uses the one of which of metal substrate, copper base or aluminium base, if the metal substrate front is laid
Dry LED lamp bead, substrate back brush insulating barrier, circuit layer, insulating barrier successively, the aluminium base is abundant with the fin of heat abstractor
Contact.
Further, each LED lamp bead installs astigmatism prism additional.
Metal substrate sets diffusion layer, and the diffusion layer includes stacking gradually the brightness enhancement film of 0 ° of arrangement, 90 ° of brightness enhancement films, expansions
Film is dissipated, liquid-crystalline glasses closing in surface is installed.
The beneficial effect for implementing the technical solution of the utility model is the characteristics of being separated with anti-reflection heat-insulated, thermoelectricity.
Brief description of the drawings
Fig. 1 is the side generalized section of the utility model open air LCD display.
Fig. 2 is the heat abstractor schematic cross-section of LCD display of the present utility model.
Specific embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Multitude of different ways with covering is implemented.
As shown in Figures 1 and 2, a kind of lockback support 2 of outdoor LCD display, including supporting display screen, it is arranged on support
On display screen 1, by the power supply 3 powered to display screen and 4 groups of circuit board being connected with power supply and reality screen inside display screen
Into the setting aluminium base 7 on the inside of display screen, it is also possible to replaced with copper base, but high cost, radiating effect will get well, on aluminium base 7
Some LED lamp beads 8 are set, and the light source for providing outdoor display screen, each LED lamp bead installs astigmatism prism 11 additional.This practicality is new
Laminating permeability improvement device 20 on the display screen panel of type, laminating has printing opacity work(high to the permeability improvement device on display screen panel successively
The AR glassy layers 21 of energy, then apply one layer of adiabatic gum 22 again, then install sensing layer 23, and outermost layer is the liquid crystal glass for protecting screen
Glass 24.The sensing layer 23 is capacitance touch layer, can be used for touch control and shows.Heat abstractor 30 is installed in display screen side,
The heat abstractor 30 by some metal fins 31 on the outside of display screen and on the inside of display screen fin connection and
Into.Metal fins are stacked in display screen side, and space, the radiating 32 inside one end of fin and display screen are left between fin
Integrally connected, coupling part is embedded in display screen side housing 33.
LCD display uses the one of which of metal substrate 7, copper base or aluminium base, the metal substrate front laying
Some LED lamp beads 8, substrate back brush insulating barrier, circuit layer, insulating barrier successively, the fin of the aluminium base and heat abstractor
32 are fully contacted, and produced heat energy is carried out by the metal fins on the outside of fin conductive to display screen by cross-ventilation
Radiating, scribbles heat conductive silica gel 9 between fin and aluminium base.
With continued reference to Fig. 1, to strengthen the brightness of display screen, metal substrate sets diffuser plate 13, on the diffuser plate successively
15,90 ° of brightness enhancement films 14 of the brightness enhancement film that 0 ° of stacked arrangement, the surface liquid-crystalline glasses closing of diffusion barrier 16 are installed, and diffuser plate back is installed
Reflectance coating 17 fixed by reflecting membrane support 18, even if installing low power LED lamp bead, also can guarantee that enough brightness, together
When also have reduce heat generation function.
Preferred embodiment of the present utility model is these are only, the utility model is not limited to, for this area
Technical staff for, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle within,
Any modification, equivalent substitution and improvements made etc., should be included within protection domain of the present utility model.
