The technical scheme of the utility model the local too high and problem of the display screen colour cast that leads to of display screen temperature among the prior art has been solved effectively.
Description
Technical field
The utility model relates to the technical field of display device, in particular to a kind of LED display.
Background technology
Along with the raising of people's living standard, the requirement of people to the resolution of display display screen is more and more higher.
In order to the resolution improving display screen needs to arrange more intensive lamp point, the driving chip matched with lamp point so also needs increase, and lamp point and driving chip all can distribute heats, and this heat that display screen is distributed increases.Amount of localized heat increase the colour cast that can cause display screen.
Utility model content
Fundamental purpose of the present utility model is to provide a kind of LED display, to solve the too high and problem of display screen colour cast that causes in display screen temperature of the prior art local.
To achieve these goals, the utility model provides a kind of LED display, comprising: backboard; LED lamp panel, is arranged on backboard; Driving chip, is arranged between LED lamp panel and backboard, is provided with Heat Conduction Material between driving chip and backboard.
Further, have gap between driving chip and backboard, Heat Conduction Material is positioned at gap.
Further, driving chip is arranged in LED lamp panel.
Further, backboard comprises framework towards the side of LED lamp panel and holds the groove of driving chip.
Further, Heat Conduction Material is contained in groove.
Further, framework comprises the frame being arranged on backboard surrounding and the inside casing be arranged in the middle of backboard.
Further, framework and LED lamp panel bond together.
Further, framework and LED lamp panel double faced adhesive tape bond together.
Further, backboard is magnesium alloy material.
Further, Heat Conduction Material is heat-conducting silicone grease.
Application the technical solution of the utility model, driving chip is arranged between LED lamp panel and backboard, is provided with Heat Conduction Material between driving chip and backboard, and Heat Conduction Material side contacts with driving chip, and opposite side contacts with backboard.Said structure on the one hand the heat conduction of driving chip and LED lamp panel to backboard, dispelled the heat by backboard; Heat Conduction Material is passed to the lower driving chip of peripheral temperature or LED lamp panel the heat of driving chip higher for local temperature or LED lamp panel on the other hand.Said structure makes the radiating effect of LED display better, efficiently avoid the too high display screen colour cast that causes of local temperature due to LED lamp panel and the easily aging problem of LED lamp panel.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:

Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the LED display of the present embodiment comprises: backboard 10, LED lamp panel 20 and driving chip.LED lamp panel 20 is arranged on backboard 10.Driving chip is arranged between LED lamp panel 20 and backboard 10, is provided with Heat Conduction Material between driving chip and backboard 10.
The technical scheme of application the present embodiment, driving chip is arranged between LED lamp panel 20 and backboard 10, is provided with Heat Conduction Material between driving chip and backboard 10, and Heat Conduction Material side contacts with driving chip, and opposite side contacts with backboard 10.Said structure on the one hand the heat conduction of driving chip and LED lamp panel to backboard, dispelled the heat by backboard; Heat Conduction Material is passed to the lower driving chip of peripheral temperature or LED lamp panel the heat of driving chip higher for local temperature or LED lamp panel on the other hand.Said structure makes the radiating effect of LED display better, efficiently avoid the too high display screen colour cast that causes of local temperature due to LED lamp panel and the easily aging problem of LED lamp panel.
Particularly, Heat Conduction Material is heat-conducting silicone grease, and above-mentioned material good heat conduction effect, cost is lower.
As shown in Figure 1, in the technical scheme of the present embodiment, have gap between driving chip and backboard 10, Heat Conduction Material is positioned at gap.Said structure, while guarantee radiating effect, makes compact conformation, saves the space of LED display.Particularly, in the technical scheme of the present embodiment, driving chip is arranged in LED lamp panel 20.Said structure makes thickness reduce on the one hand, compact conformation, and the integral thickness of LED display can be reduced to 11mm particularly, saves material on the other hand, alleviates the weight of LED display, saved cost.
As shown in Figure 1 to Figure 3, in the technical scheme of the present embodiment, backboard comprises framework 11 towards the side of LED lamp panel and holds the groove 12 of driving chip.Particularly, arranging of groove 12 can carry out empty avoiding setting according to driving chip in the position of LED lamp panel 20 projection and shape, and such as groove 12 is multiple, and groove 12 comprises big groove, arranges little groove in big groove.The setting of said structure further mitigates the weight of LED lamp panel, makes structure compacter.
As shown in Figures 2 to 4, in the technical scheme of the present embodiment, Heat Conduction Material is contained in groove 12.Particularly, driving chip and have certain gap between groove bottom wall and sidewall, Heat Conduction Material is arranged in these gaps, and the back side of backboard 10 is provided with reinforcement, and the Total Product compact conformation of said structure, intensity are high, safe and reliable.
Preferably, backboard 10 is magnesium alloy material, and this material weight is light, and hardness is high, and heat-transfer effect is good.The heat of such golf calorific value driving chip can be led away rapidly by Heat Conduction Material very soon.Because overall thermal conductivity can be good, the inner institute of such LED display temperature a little reaches unanimity, and avoids the colour cast that lamp point causes because temperature is different.It also avoid the problem appearance occurring that local temperature is too high simultaneously.The service life reduction above configuration reducing LED and the control device caused because temperature is too high is dangerous.
As shown in Figure 1, in the technical scheme of the present embodiment, framework 11 comprises the frame being arranged on backboard 10 surrounding and the inside casing be arranged in the middle of backboard 10.Framework 11 the intensity strengthening on the one hand backboard 10 is set, preferably, LED lamp panel 20 has the structure matched with framework 11, and framework 11 and LED lamp panel 20 are bonded together, and said structure is compact, arranges simple.Further preferably, framework 11 and LED lamp panel 20 double faced adhesive tape 30 bond together.Said structure easily operates, and installation effectiveness is higher.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
