Abstract
The utility model discloses a direct type backlight panel, which comprises a substrate, wherein an LED lamp is arranged on the substrate, the substrate is fixedly provided with a diffusion plate which is provided with a groove for containing the LED lamp, one side of the diffusion plate, which is far away from the LED lamp, is provided with an anti-reflection film, and the outer side of the anti-reflection film is provided with an LCD panel. In the utility model, the LED lamp is directly embedded in the groove on the diffusion plate, simultaneously omits a light guide plate and an air layer commonly used in the prior art, greatly reduces the thickness of the backlight panel, reduces the cost, reduces light loss due to the omission of the air layer, and increases the utilization ratio of light emitted by the LED lamp.
Description
Technical field
The utility model relates to a kind of LED-backlit panel, relates in particular to a kind of direct-light type LED backlight panel.
Background technology
The passive display device reflection of LCD or absorbing environmental daylight or room light are with display image on the LCD panel, so the user needs environment daylight or room light to watch shown image.But the undercapacity of environment daylight or room light with the situation that illuminates display panel under, exist the user can't see the problem of the shown image of LCD clearly.As the replacement scheme of this problem, use the backlight panel that display panel is carried out back lighting usually.
Backlight panel comprises for example light source of incandescent lamp, fluorescent light or light emitting diode.From the bright LCD panel of the illumination of light emitted, and therefore realized image.Simultaneously, because LED has good reproduction, the back light of doing commonly used.
Be to use light emitting diode (LED) LCD panel 17 to be carried out the partial section of the conventional backlight panel of back lighting as shown in Figure 1.
Referring to shown in Figure 1, LED lamp 3 arrayed are on printed circuit board (PCB).LED lamp 3 is red, green, blue arrays of arranging with predetermined space.LED lamp 3 is arranged on the printed circuit board (PCB) with rule sequence and constitutes led module, and uses a plurality of led modules that the LCD panel is carried out back lighting.
The light that reflector plate 5 is positioned at LED lamp 3 leaves lower face.Reflector plate 5 is upwards reflecting from the light of LED lamp 3 reflections upward.
Diffuser plate 11 is positioned at light guide plate 7 tops and is spaced from.Diffuser plate 11 separates each other predetermined space to define second gap 10 (it is an air layer) with light guide plate 7.
The anaclasis that prismatic lens 13 and dual prismatic lens 15 will be launched with bigger displaying angle from diffuser plate 11 is the light with less displaying angle, makes light can incide on the LCD panel 17.Therefore, the luminosity of LCD panel 17 increases.
Because the existence of the air layer in first gap 6 and second gap 10 is arranged, can cause the thickness of backlight panel to increase, when light mixes, lost a part of light in the air layer in first gap 6 and second gap 10, the utilization factor of light is reduced.
The utility model content
Technical problem to be solved in the utility model provides the luminous utilization factor of a kind of raising LED, and can reduce the downward back optic panel of backlight panel thickness.
For solving the problems of the technologies described above, the technical solution of the utility model is: the downward back optic panel, comprise substrate, the LED lamp is installed on the described substrate, be installed with diffuser plate on the described substrate, described diffuser plate is provided with the groove that holds described LED lamp, and the side away from described LED lamp on the described diffuser plate is provided with anti-reflection film, and the outside of described anti-reflection film is provided with the LCD panel.
As a kind of improvement, described anti-reflection film comprises prismatic lens that contacts with described diffuser plate surface and the dual prismatic lens that is arranged on the described prismatic lens outside.
As further improvement, the installed surface that described LED lamp is installed on the described substrate is provided with the reflection horizon.
As further improvement, described substrate is an aluminum-based circuit board.
As further improvement, described reflection horizon is the nanometer reflection horizon.
As further improvement, described LED lamp is a white LED lamp.
Owing to adopted technique scheme, the downward back optic panel, comprise substrate, the LED lamp is installed on the described substrate, be installed with diffuser plate on the described substrate, described diffuser plate is provided with the groove that holds described LED lamp, and the side away from described LED lamp on the described diffuser plate is provided with anti-reflection film, and the outside of described anti-reflection film is provided with the LCD panel; The beneficial effects of the utility model are: the LED lamp directly is embedded in the groove on the diffuser plate, normally used light guide plate and air layer in the prior art have been saved simultaneously, greatly reduce the thickness of backlight panel, reduced cost, the omission of air layer has also reduced the loss of light, has improved the utilization factor that the LED lamp sends light.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram;
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 2, the downward back optic panel comprises substrate 1, and described substrate 1 is a metal circuit board, is preferred with the aluminum-based circuit board, and aluminum-based circuit board can well be distributed the heat that the LED lamp produces.
The surface of described aluminum-based circuit board is provided with diffuser plate 5.
On the described substrate 1 and with surface of contact that described diffuser plate 5 contacts on white LED lamp 4 is installed, LED lamp 4 can be installed on the aluminum-based circuit board by array way, the setting of white LED lamp 4 need not to reduce the thickness of backlight panel with the air layer that ruddiness, green glow, blue light are mixed with each other.
On the described diffuser plate 5 and the surface of contact that contacts with described substrate 4 be provided with the groove 2 that holds described LED lamp 4, the LED lamp 4 that is installed on the aluminum-based circuit board just in time is positioned at groove 2, thereby LED lamp 4 is embedded in the described diffuser plate 5, saved the space, reduced the thickness of present embodiment, simultaneously can omit light guide plate, when simplifying technology and save cost, thereby further reduce the thickness of downward back optic panel.
The installed surface that LED lamp 4 is installed on the described substrate 1 is provided with the reflection horizon, reflection horizon in the present embodiment is for directly being plated in the nanometer reflection horizon 3 on the substrate 1, and the general independent reflector plate that is set in reflection horizon of the prior art, compared with prior art nanometer reflection horizon 3 is thinner, and saved the mounting process that reflector plate is installed, by the setting of nanometer reflection horizon 3 replacement reflector plates, further reduced the thickness of downward back optic panel.
Side away from described LED lamp 4 on the described diffuser plate 5 is provided with anti-reflection film, and the outside of described anti-reflection film is provided with LCD panel 8.Described anti-reflection film comprises prismatic lens 6 that contacts with described diffuser plate 5 surfaces and the double-deck prismatic lens 7 that is arranged on described prismatic lens 6 outsides, LCD panel 8 is installed in the outside surface of double-deck prismatic lens 7, anti-reflection film is to be used for being collected in the light that comes out from diffuser plate 5 in a certain displaying angle, to increase the luminosity of light.
The utility model has saved light guide plate and the air layer in the traditional structure, thereby reduced backlight panel thickness, when having simplified manufacture craft, has also improved the utilization factor that LED sends light.
